Question:
Ellen mixed ¼ kg of flour with ²/9 kg of sugar.
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. However, question that are likely to be asked are.
- What's the weight of the total mixture in grams
- What percentage of the mixture is sugar
To solve (1);
We simply add both weights together
But first, the units must be converted to grams.
1kg = 1000 grams
So,
¼kg = ¼ * 1000 g
¼kg = 250 g
²/9kg = ²/9 * 1000
²/9kg = 2000/9
²/9kg = 222.2 g
Add these results
Total = 250g + 222.2g
Total = 472 g
The result can be written in different ways
1. 472 grams
2. About 500 grams
If converted back to kg
472 grams = 472/1000 kg
472 grams = 0.472 kg.
So, the result can also be written as
3. 0.472 kg
4. About 0.5kg (½kg)
To solve (2)
What percentage of the mixture is sugar
To do this, we simply divide the size of sugar by the total size of the mixture.
From (1) above
Sugar = 250g
Total = 472g
Percentage of sugar = 250/472
Percentage of sugar = 0.5297
Percentage of sugar = 0.5297 * 100%
Percentage of sugar = 52.97%

Answer:
C. Translation 5 units left and 2 units down
Step-by-step explanation:
Let's take a look at A', which is (0, 0). This is the result of A, which is (5, 2) being transformed somehow. Notice that the x-coordinate moved 5 units to the left (from 5 to 0, which means we subtract 5 from 5). And, notice that the y-coordinate moved 2 units down (from 2 to 0, so we subtract 2 from 2).
Look to see if this works for the other two points:
B(6, 1): if we subtract 5 from the x-coordinate 6, we get 6 - 5 = 1, which matches the x-coordinate of the image B'. If we subtract 2 from the y-coordinate of B, which is 1, we get 1 - 2 = -1, which also matches the y-coordinate of B'. So, this works.
C(4, 5): if we subtract 5 from the x-coordinate 4, we get 4 - 5 = -1, which matches the x-coordinate of the image C'. If we subtract 2 from the y-coordinate of C, which is 5, we get 5 - 2 = 3, which also matches the y-coordinate of C'. So, this again works.
Therefore, we know that the transformation is a translation 5 units left and 2 units down, or C.
A picture will be shown below of a graph with the points in the table.
We only need to use (5, 2) and (0, 0) to solve this problem.
We take both points and see what it took for the old point to get to where the new point is (Shown in picture below).
Therefore, the answer is [ C. Translation 5 units left and 2 units down ]

2) Shawn's cat is currently stuck in a tree. Shawn has a ladder that is 15 feet long and he places the ladder 10 feet from the base of the tree. At what angle of depression is Shawn's cat looking at him?
Answer:
48.19°
Step-by-step explanation:
Check the attachment for the diagram.
The set up is a right angled triangle
Using the SOH, CAH, TOA trigonometry ratio to get the angle of depression theta.
The length of the ladder will be the hypotenuse of the triangle.
If he places the ladder 10 feet from the base of the tree, the adjacent of the triangle will be the base of the triangle.
Given Hypotenuse = 15feet
Adjacently = 10feet
According to CAH;
cos(theta) = Adjacent/Hypotenuse
cos(theta) = 10/15
cos(theta) = 2/3
theta = arccos(2/3)
theta = 48.19°
Shawn cat is looking at him at an angle of depression of 48.19°
The carrying capacity of a biological species in an environment is the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment. Why is a population that overshoots the carrying capacity can only do so for a limited amount of time?
Answer:
A population that overshoots the carrying capacity can only do so for a limited amount of time because: since the ecosystem already has the maximum number it can take for a given specie, overshooting the ecosystem will not last long as:
1. Competitions for the limited available space and resources will result to increase death rate and emigration from the environment.
2. Birth rate would be controlled as the rate resources are used is greater than they are replenished. This limits productivity among species.
Step-by-step explanation:
The carrying capacity of an environment, in simple terms is the amount of a given specie that the environment can sustain without depleting or degrading the available resources. Population size of an environment increases if birth rate increases and death rate decreases, and if the environment also experience an increase in species coming to live there than they are leaving the environment. In other words, when resources are limited it affects the population size of an environment.

Can adjacent angles be complementary?
Give a brief explanation as to why or why not.
Answer:
Two adjacent angles can be complementary
Step-by-step explanation:
if they add up to 90°. For example, a diagonal of a square will split the right angle into two equal angles; 45°+45°. In a right triangle, the altitude from a right angled vertex will split the right angle into two adjacent angles; 30°+60°, 40°+50°, etc.

A spinner with seven equal sized sections was used to play a game It was used 250 times in the first game Of those 250 the arrow landed on section 7 a total of 35 times The same spinner was used 150 times in the second game How many times did the spinner most likely land on section 7 in the second game A. 14 B. 21 C. 30 D. 35
Answer: 21
Step-by-step explanation:
From the question, a spinner with seven equal sized sections was used in playing a game. The spinner was used 250 times in the first game and the arrow landed on section 7 a total of 35 times. This can be expressed as:
= 35/250
= 0.14
The same spinner was also used 150 times in the second game. The number of times the spinner will most likely land on section 7 in the second game will be:
= 0.14 × 150
= 21
The spinner most likely land on section 7 in the second game for 21 times.
How do I solve this problem? I need to find the volume of this composite figure.
Step-by-step explanation:
V = (12*4*5) + (2*3*5) + (5*3*5) + (12*4*5)
V = 240 + 30 + 75 + 240
V = 585 cm^3
What is the volume, in cubic in, of a rectangular prism with a height of 6in, a width of 10in, and a length of 2in?
The answer is 120
do 6 times 10 = 60
then 60 x 2 = 120 cubic in
120 cubic in is the volume of the rectangular prism.
What is volume?Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m³), a derived unit, is the SI unit of volume. Volume is another word for capacity.
The volume of a rectangular prism is given by the formula:
V = lwh,
where l is the length, w is the width, and h is the height.
Plugging in the given values, we get:
V = (2 in) x (10 in) x (6 in)
V = 120 cubic in
Therefore, the volume of the rectangular prism is 120 cubic in.

A missing data value from a set of data has a z-score of –2.1. Fred already calculated the mean and standard deviation to be Mu = 43 and Sigma = 2. What was the missing data value? Round the answer to the nearest whole number. 39 41 45 47
Answer:
39
Step-by-step explanation:
i just did it on usa test prep
Using the normal distribution, it is found that the missing data value was of 39.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.In this problem, we have that:
[tex]\mu = 43, \sigma = 2, Z = -2.1[/tex]
The missing data value is X, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]-2.1 = \frac{X - 43}{2}[/tex]
[tex]X - 43 = -4.2[/tex]
[tex]X = 38.8[/tex]
Rounding up, the missing data value was of 39.

The perimeter of quadrilateral ABCD is 640. The perimeter of quadrilateral LMNO is 144. What is LM
Answer:
LM = 36
Step-by-step explanation:
A quadrilateral is a shape with 4sides. There are different type of quadrilateral such as square, rectangle, trapezium, parallelogram, kite and rhombus.
Perimeter of a quadrilateral is the addition of all 4 sides.
Since the shape is not specified neither is there a diagram, let's assume the quadrilateral is a square.
See attachment for diagram used in solving the question.
Perimeter of square = length+ length+ length+ length
= 4× length
Perimeter of quadrilateral ABCD:
640 = 4×length
Length = 640/4
Length = 160
Perimeter of quadrilateral LMNO:
144 = addition of all 4 lengths
144 = LM + MN + NO +OL
Since we are considering a square all the sides are equal.
LM = MN = NO = OL
144 = 4×LM
LM = 144/4
LM = 36

22 miles
4 miles
31 miles
17 miles
Answer:
4 miles
Step-by-step explanation:
Suppose we have two points:
[tex]A = (x_{1}, y_{1})[/tex]
[tex]B = (x_{2}, y_{2})[/tex]
The distance between these points is:
[tex]D = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
In this question:
Points (-8, -9) and (-4, -10).
So the distance is:
[tex]D = \sqrt{(-8 - (-4))^{2} + (-9 - (-10))^{2}} = \sqrt{17} = 4.12[/tex]
The distance is 4.12 miles.
Rounding to the nearest mile, 4 miles.

The owner of a coffee shop compared the amount of hot coffee per day, in fluid ounces, sold and the daily high temperature, in degrees Fahrenheit, per day. Her data are shown in the scatter plot below. If these data are modeled by the line y = -5.9x + 850, which statement best describes a valid prediction the owner could make?
Picture of the question is attached below.
Answer: B.) For each temperature decrease of 10°F, the shop can expect to sell about 6 fluid ounces more of hot coffee.
Step-by-step explanation:
The model depicted by the line equation:
y = -5.9x + 850 shows a strong negative linear relationship between the amount of hot coffee per day, in fluid ounces, sold and the daily high temperature, in degrees Fahrenheit, per day. This means that the sale of hit coffee decreases with increasing temperature daily, which makes sense. From the plot and line model equation, the shop can expect to sell about 6 fluid ounces less of hot coffee for each temperature ruse of 10F.
-5.9x approximately -6x decrease for every 10F temperature increase.
