Answer:
The formula would be a squared + b squared = c squared
Step-by-step explanation:
The a and b would be the legs of the triangle (the two shorter sides). The c would be the hypotenuse (The longest side). You would need to plug in the numbers that you have to solve for the missing one.

Answer: 56° and 34°
Step-by-step explanation: Well we know this is a complementary angle and if two angles are complementary, then the sum of their measures is 90 degrees.
If these two angles have to add together to be 90 degrees, we can use that fact to set up our equation. We can say that 4x + (2x + 6) = 90.
Simplifying from here, we have 6x + 6 = 90.
Subtracting 6 from both sides, we have 6x = 84.
Dividing both sides by 6, we find that x = 14.
Now, remember that these should add up to 90 degrees.
We can check by substituting the value that we just found back in for x to check our angles. If they add to 90 degrees, we did it correctly.
So for the first one we have 4(14) which is 56 and for the next one we have 2(14) + 6 or 28 + 6 which simplifies to 34.
Now adding, 56 + 34 gives us 90.
So, we know that these are the correct measures.
The price of a cup of coffee was $2.35 yesterday. Today, the price fell to $2.10. Find the percentage decrease. Round your answer to the nearest tenth of a percent.
Answer:
10.6% decrease
Step-by-step explanation:
The percentage change in a quantity is computed using ...
percentage change = ((new value)/(old value) -1) × 100%
= (2.10/2.35 -1) × 100%
= (0.8936 -1) × 100%
= -.1064 × 100%
= -10.64%
The percentage decrease was about 10.6%.

Which statement about liters and milliliters is true?
Answer:
Lesson Summary
A milliliter is a metric unit used to measure capacity that's equal to one-thousandth of a liter. Capacity is the amount of liquid a container can hold. One liter contains 1,000 milliliters, so to convert liters to milliliters you multiply the number of liters times 1,000.
Look at the equivalent metric units of capacity. When converting from a larger unit to a smaller unit, multiply by 1,000. When converting from a smaller unit to a larger unit, divide by 1,000. Liters are larger than milliliters, so multiply by 1,000.

Since two of the eight ads are by a local retailer, the probability of picking either one once is 2/8=1/4. However, the second time, since on of the ads has already been used and there are a total of 7 left, the new probability is 1/7. Multiplying these two together, you get 1/4*1/7=1/28.
4.
To find the probability, you need to find the area of the smaller triangle and the rest. The formula for the area of an equilateral triangle is [tex]\frac{\sqrt{3}}{4}a^2[/tex], meaning that the area of the big triangle is [tex]56.25\sqrt{3}[/tex] and the area of the little triangle is [tex]4\sqrt{3}[/tex]. [tex]\frac{4\sqrt{3}}{56.25\sqrt{3}}\approx 7.11\%[/tex]. Hope this helps!

D. 2/16
Answer:
the correct answer is 2/200
Step-by-step explanation:

What is probability?The probability of an event is a number that indicates how likely the event is to occur.
It is expressed as a number in the range from 0 and 1, or, using percentage notation, in the range from 0% to 100%.
The more likely it is that the event will occur, the higher its probability.
Given that, the result of a survey of 200 adults are shown in the table,
We need to find the probability that a randomly chosen person from the survey is female and at least 6 feet tall,
P(E) = favorable outcomes / total outcomes
= 2 / 200
Hence, the probability that a randomly chosen person from the survey is female and at least 6 feet tall is 2/200

I would appreciate it Brainly7532 Question 1 of 7 The equation 4x – 45 = y is used to find your profit, y, in dollars from buying $45 of supplies and washing cars for $4 each. What does the x stand for?
Answer:
x stands for the number of cars washed with the supplies.
Step-by-step explanation:
Given;
Profit equation; y = 4x - 45
Price of supplies = $45
Amount received per car wahed = $4
From the equation given, we can notice that the higher the value of x the higher the profit generated.
Since, for washing a car brings $4, 2 car is $8 and so on... So the value of x is the number of cars washed with the supplies.
x stands for the number of cars washed with the supplies.
For example, if we wash 15 cars. x = 15
y = 4(15) - 45 = 60 - 45
y = $15

x^2+y=3

solve by using substitution
show work please
Answer:
x = 2
y = -1
Step-by-step explanation:
x² + y = 3 --------------------(i)
x² = 3 - y
x² - y = 5 ---------------------(ii)
substitute x² = 3 - y in equation (ii)
x² - y = 5
3 - y -y = 5 {Add like terms}
3 - 2y = 5 {Subtract 3 from both sides}
3 - 2y -3 = 5 - 3
-2y = 2 {divide both sides by -2}
-2y/-2 = 2/-2
y = -1
Substitute the value of y in equation (i)
x² + y = 3
x² - 1= 3 {Add 1 to both sides}
x² - 1 + 1 = 3+ 1
x² = 4
x = √4
x = 2

You roll a six-sided die. What is the probability that it is a 5 or an even number? Write your answer as a decimal rounded to the nearest
thousandth
Answer:
.667
Step-by-step explanation:
4/6 = 2/3 = .667
The probability that it is a 5 or an even number is 5/6 or 0.834 if
you roll a six-sided die.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words, the probability is the number that shows the happening of the event.
Number of total outcomes = 6
P(5) = 1/6
P(even) = 4/6
The probability that it is a 5 or an even number:
P = 1/6 + 4/6 = 5/6
P = 0.834
Thus, the probability that it is a 5 or an even number is 5/6 or 0.834 if
you roll a six-sided die.

The total percentage of all the students who are left handed is 26%.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Ratio of boys to girls = 2 : 3
Number of boys in fractional form = 2/(2 + 3) = 2/5
Number of girls in fractional form = 3/5
Percentage of boys = 2/5 × 100 = 40%
Percentage of girls = 100% - 40% = 60%
Of these 40%, 20% are left handed.
⇒ 40% × 20% = 0.08 = 8%
So 8% of boys of the total students is left handed.
70% of the girls are right handed. Then 30% of girls are left handed.
Of 60% of total girls, 30% are left handed.
30% × 60% = 18%
So 18% of girls of the total students are left handed.
Total percentage = 18% + 8% = 26%
Hence the total percentage of left handed students is 26%.

The sale price of ground beef at a local grocery store is $1.49 for the first pound and $1.09 for each additional pound. Which function rule shows how the cost of ground beef, y depends on the number of pounds, x?
Answer:
y=1.09x+0.4
Step-by-step explanation:
Let's assume that the price of beef stays the same for every pound of beef (the first pound is also $1.09)
Then, the equation would be, it y was the cost, and x was pounds:
y=1.09x
But, the price of beef is not the same for the first pound.
The first pound costs an extra 1.49-1.09=0.4 dollars a pound, so we will add that to the equation.
y=1.09x+0.4
Starting at 1:00 p.M., The temperature changes -4 degrees Fahrenheit per hour. Write and solve an equation to find how many hours (x) it will take to reach -1 °F.
Answer: it will take 5 hours to reach -1 °F.
Step-by-step explanation:
The temperature changes -4 degrees Fahrenheit per hour. This is a linear rate. The rate at which the temperature is decreasing is in arithmetic progression. The formula for determining the nth term of an arithmetic sequence is expressed as
Tn = a + (n - 1)d
Where
a represents the first term of the sequence(the starting point)
d represents the common difference.
n = x = the number of terms in the sequence(number of hours)
From the information given,
a = 0(at 1 pm, number of hours is 0)
d = - 4 degrees (it is decreasing)
Tn = -1 °F.
We want to determine the number of hours, x when Tn = -1 °F
Therefore,
- 1 = 0 + (x - 1)- 4
- 1 = - x + 4
x = 4 + 1
x = 5 hours

Find the area of a circle with a diameter of 56 millimeters.
Answer: 784π mm²
Step-by-step explanation: To find the area of a circle, start with the formula for the area of a circle which is shown below.
Area = πr²
Notice that here, we're given the diameter instead of the radius.
Remember that the radius is equal to half of the diameter. So the radius of this circle will be equal to half 56 millimeters or 28 millimeters.
So plugging into the formula, we have (π)(28 mm)².
A common mistake is to plug 56 millimeters into the formula but remember that we must plug in the radius and not the diameter.
Multiplying, (28 mm)² is equal to (28 mm)(28 mm) or 784 mm².
So we have 784π mm².
So the area of the circle is 784π mm².
