Elliott has some yarn that she wants to use to make hats and scarves. Each hat uses 0.2, point, 2 kilograms of yarn and each scarf uses 0.1, point, 1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats, and she wants to make a total of 20 items. Let h be the number of hats Elliott makes and s be the number of scarves she makes. Which system of equations represents this situation?
Answer:
Step-by-step explanation:
Let h be the number of hats Elliott makes and s be the number of scarves she makes.
Each hat uses 0.2 kilograms of yarn and each scarf uses 0.1 kilograms of yarn. Elliott wants to use twice as much yarn for scarves as for hats. This is expressed as
h = 2s
The total number of hats and scarves that she wants to make is 20. This is expressed as
h + s = 20
Therefore, the system of equations that represents this situation are
h = 2s
h + s = 20

Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
Answer:
2p + 2d = 39 ____________(1)
8p + 10d = 174.50 _________(2)
Price of one drink is $9.25
Step-by-step explanation:
Let the price of a bag of popcorn be p.
Let the price of a drink be d.
Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:
2p + 2d = 39 ____________(1)
Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:
8p + 10d = 174.50 _________(2)
We now have two system of equations which we can use to find the price of a bag of popcorn and drink:
2p + 2d = 39 ____________(1)
8p + 10d = 174.50 _________(2)
Multiply (1) by 4 subtract from (2):
8p + 10d = 174.50 _______(2)
- 8p + 8d = 156 __________(1)
2d = 18.50
=> d = $9.25
The price of one drink is $9.25

53 students are going on a field trip to the museum of modern art. Each bus holds 40 people. How many buses must be used to transport all the students
Answer:
2
Step-by-step explanation:
If you take 1 bus then that means leaving 13 peoplee brhind(53-40=13), so you have to take 2 buses.
53 students are going on a field trip to the museum of modern art.
Each bus holds 40 people. we need 2 buses to hold the all students.
What is addition?The addition is one of the mathematical operations. The addition of two numbers results in the total amount of the combined value.
53 students are going on a field trip to the museum of modern art.
Each bus holds 40 people.
Total students left = 53 - 40
= 13
one bus can hold a number of students = 40
but we have 13 more students which are less than 40.
So, we need one more bus to hold the leftover.

Answer:
x=30
Step-by-step explanation:
Sin 60 = ((√3)/2), so x=90-60. x=30.
The required value of x for function sin(90°– x)= - √3/2 is x =150°.
A function is given as sin(90°– x)= - √3/2, Value of x for the function is to be determined.
What are trigonometric equations?The equation contains trigonometric operators such as sin, cos.. etc. In algebraic operation.
sin(90°– x)= - √3/2
sin(90°– x) = -sin60
90°-x = sin(-60°)
90°-x = -60°
-x = -60°-90°
x = 150°
Thus, the required value of x for function sin(90°– x)= - √3/2 is x =150°.

Priya asked each of five friends to attempt to throw a ball in a trash can until they succeeded. She recorded the number of unsuccessful attempts made by each friend as: 1, 8, 6, 2, 4. PRIYA MADE A MISTAKE: The 8 in the data set should have been 18. How would changing the 8 to 18 affect the MEDIAN of the data set? *
Answer:
1,2,4,6,8
And the median can be calculated from the value in the position 3th and we got 4
[tex] Median =4[/tex]
And now using the correct dataset is: 1, 18, 6, 2, 4. And if we order the dataset we got:
1,2,4,6,18
And the median for this case again would be the value in the 3th position and we got:
[tex] Median =4[/tex]
So then we can conclude that the median is unaffected by the change of 18 instead of 8
Step-by-step explanation:
For this case we have the original dataset given:
1, 8, 6, 2, 4
And the median for this dataset can be calculated with the following dataset ordered:
1,2,4,6,8
And the median can be calculated from the value in the position 3th and we got 4

James has a lot of games. Samuel, his friend, has 4 times as many games as James. Write an algebraic expression to represent how many games James has and how many games Samuel has in terms of g.
Answer: The answer is given below
Step-by-step explanation:
From the question, James has a lot of games while his friend Samuel, has 4 times as many games as James.
Let the number of games James has be represented by g.
Since Samuel has 4 times as many games as James, then Samuel's game will be:
= 4 × g
= 4g
The expression for James is g.
The expression for Samuel is 4g.

The sun is 62 degrees above the horizon. A tree casts a shadow that is 12 feet long. How tall is the tree?
Answer:
22.6 feet
Step-by-step explanation:
Let x be the length of tree
tan(62) = x/12
x = 12tan(62)
x = 22.56871758
The height of the given tree is required.
The height of the tree is 22.57 feet.
[tex]\theta[/tex] = Angle of elevation = [tex]62^{\circ}[/tex]
s = Length of shadow = 12 feet
t = Tree height
From the trigonometric ratios we get
[tex]\tan \theta=\dfrac{t}{s}\\\Rightarrow t=s\tan\theta\\\Rightarrow t=12\times \tan62^{\circ}\\\Rightarrow t=22.57\ \text{feet}[/tex]
The height of the tree is 22.57 feet.

1) How many viewers will be there in one year? Use commas. Show your reasoning.
2) Estimate on which day will 640 people see the video? Show your reasoning.
Answer:
Step-by-step explanation:
Given
When video is posted 5 people watched it
Next day number of viewers doubled
Suppose this trend continues i.e. No of viewers doubled each day
So on 2 nd day no of viewers is [tex]2\times 5[/tex]
On 3rd day , viewers [tex]2^2\times 5[/tex]
on n th day , viewers is [tex]2^{n-1}\times 5[/tex]

The correct question is;
You spin the spinner, flip a coin, then spin the spinner again. Find the probability of the compound event. Write your answer as a fraction or percent. If necessary round your answer to the nearest hundredth. Find the probability of spinning an odd number, flipping heads, then spinning another odd number? Write your answer as a fraction in simplest form.
Answer:
If the spinner has an even number of spaces, the probability of spinning an odd number, flipping heads, then spinning a yellow is = 1/8
Whereas, if the spinner has an odd number of spaces, more information is needed
Step-by-step explanation:
The answer will depend on whether the spinner has an odd or even number of spaces.
Now, if we suppose that the spinner has an even amount of numbers on it, there will be an equal number of odd and even numbers.
Thus the probability of spinning an odd number is ½.
Also, the probability of flipping heads on a coin is ½.
Thus, the probability of spinning an odd number, flipping heads, then spinning another odd number is;
= ½ × ½ × ½ = ⅛
Similarly,
If the spinner has an odd amount of numbers on it, the probability of spinning an odd number will vary. For instance, if there are 5 spaces on the spinner, the probability of spinning an odd number will be
3
However, if there are 9 spaces, the probability will be 5/9
So,we can conclude that;
If the spinner has an even number of spaces, the probability of spinning an odd number, flipping heads, then spinning a yellow is = 1/8
Whereas, if the spinner has an odd number of spaces, more information is needed.

Solve x^2 -24 = -80 by completing the square.
What is the solution set of the equation?
A.(2,40)
B.(4,20)
C.(5,16)
D.(8,10)
Answer:
B.(4,20)
Step-by-step explanation:
Given: [tex]x^2 -24x = -80[/tex]
To solve the quadratic equation by completing the square, we follow these steps.
Step 1: Divide the coefficient of x by 2
[tex]-\dfrac{24}{2}=-12[/tex]
Step 2: Square your result fro Step 1
[tex](-12)^2[/tex]
Step 3: Add the result form step 2 to both sides of the equation
[tex]x^2 -24x+(-12)^2 = -80+(-12)^2[/tex]
Step 4: Rewrite the Left hand side in the form [tex](x+k)^2[/tex]
[tex](x-12)^2=-80+144\\(x-12)^2=64[/tex]
Step 5: Take square roots of both sides
[tex]x-12=\pm \sqrt{64}[/tex]
Step 6: Solve for x
[tex]x=12\pm \sqrt{64}\\=12\pm8\\x=12+8$ or x=12-8\\x=20 or x=4.[/tex]
Therefore, the solution set of the equation is (4,20).
