Answer: 26
We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.
Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.
Hope this helps.
y is inversely proportional to d²
When d = 10, y = 4
d is directly proportional to x²
When x = 2, d = 24
Find a formula for y in terms of x.
Give your answer in its simplest form.
Answers
Answer:
y = 100 / (9x⁴)Step-by-step explanation:
y is inversely proportional to d²
y = k/d²When d = 10, y = 4:
4 = k/10² k = 400y is:
y = 400/d²d is directly proportional to x²
d = mx²When x = 2, d = 24
24 = m*2²m = 24/4m = 6d is:
d = 6x²Find a formula for y in terms of x:
y = 400 / d² = 400 / (6x²)² = 400 / (36x⁴) = 100 / (9x⁴)Solve five times two and one sixth. (2 points)

Step-by-step explanation:
So you just needed help w/ C, right? Measure the bottom rectangle first, 6 * 2 = 12. Then add the area of the triangle on top. The area of a triangle equals half of base times height. In this case, it's half of 6 times 2, or just six. 12 + 6 = 18.

A cube has a side length of 13 millimeters. What is the surface area of the cube?
Answers
1. To find the difference between the temperatures, we simply subtract the smaller temperature from the larger temperature. In this case, the smaller temperature is -4°F and the larger temperature is 6°F. So the difference between the temperatures is:
6°F - (-4°F) = 6°F + 4°F = 10°F
Therefore, the difference between the temperatures is 10°F.
2. If the Suarez family spends 30% of their income on the house payment, then the remaining 70% of their income is used for other expenses. We can set up an equation to solve for their income:
0.7x = income after house payment
x = total income
We know that the house payment is $1,200, so we can substitute that into the equation:
0.7x = x - 1200
Solving for x, we get:
0.3x = 1200
x = 1200 / 0.3
x = $4,000
Therefore, the family's income is $4,000.
3. Simplifying the expression 2a-2b-4a-1b, we can combine like terms:
2a - 4a - 2b - 1b = -2a - 3b
So the simplified expression is -2a - 3b.
4. To produce a random sample of students, Carlin should use a method that gives each student an equal chance of being selected. One such method is simple random sampling, where each student is assigned a number and a random number generator is used to select the desired number of students. Another method is systematic sampling, where every nth student on a list is selected. However, other methods such as convenience sampling or voluntary response sampling may introduce bias and should be avoided if a truly random sample is desired.
1. To find the difference between the temperatures, we subtract the smaller temperature from the larger temperature: 6°F - (-4°F) = 10°F. Therefore, the difference in temperature is 10°F.
2. If the Suarez family spends 30% of their monthly income on the house payment and the payment is $1,200, we can set up the equation:
0.3x = 1200
Solving for x, we get:
x = 1200 / 0.3 = $4,000
Therefore, the family's income is $4,000.
3. Simplifying the expression 2a - 2b - 4a - 1b, we can combine like terms:
2a - 4a - 2b - 1b = -2a - 3b
Therefore, the simplified expression is -2a - 3b.
4. To produce a random sample, we need to select individuals randomly from the population. Option c, surveying every 15th student who enters the cafeteria at lunchtime, is the only method listed that produces a random sample.
5. Evaluating -8 + 8, we can see that the terms cancel each other out, so the result is 0.
6. To find the total amount Mary spent for the jeans and sweater including sales tax, we can calculate:
Total cost = Cost of jeans + Cost of sweater + Sales tax
Total cost = $30 + $35 + 0.06($30 + $35)
Total cost = $30 + $35 + $3.3
Total cost = $68.3
Therefore, Mary spent $68.3 in total for the jeans and sweater.
7. To find the change in stock value after three days, we can add and subtract the values given:
-1/2 + 3/4 - 3/8 = 1/8
Therefore, the change in stock value after three days is 1/8.
8. To factor the expression using the greatest common factor, we can factor out 4x:
4x(3x - 2) - 2(3x - 2)
= (4x - 2)(3x - 2)
= 2(2x - 1)(3x - 2)
Therefore, the factored expression is 2(2x - 1)(3x - 2).
9. To find the total amount that Nigel pays back after one year, we can use the formula:
Total amount = Principal + Simple interest
Simple interest = Principal x Rate x Time
In this case, the principal is $250, the rate is 5.5%, and the time is 1 year.
Simple interest = $250 x 0.055 x 1 = $13.75
Total amount = $250 + $13.75 = $263.75
Therefore, Nigel pays back $263.75 in total.
10. If the fish's depth is -3/4 mile, the turtle's depth is (1/3)(-3/4) = -1/4 mile. Therefore, the turtle's depth is -1/4 mile.
11. To find the difference between the expressions, we can subtract the second expression from the first:
(2x^2 + 3x - 1) - (3x^2 - 2x + 3)
= 2x^2 + 3x - 1 - 3x^2 + 2x - 3
= -x^2 + 5x - 4
Therefore, the difference of the expressions is -x^2 + 5x - 4.
12. The surface area of a cube is given by the formula 6s^2, where s is the length of one side of the cube. In this case, s = 13 mm, so we can calculate:
Surface area = 6(13^2)
Surface area = 6(169)
Surface area = 1014 mm^2
Therefore, the surface area of the cube is 1014 square millimeters.

Answers
Answer:
A = 84 \(ft^{3}\)
Step-by-step explanation:
To find the area of a trapezoid, use this equation:
\(A = \frac{a+b}{2}h\)
a = top base
b = bottom base
h = height
Let's classify all the sides:
a = 4 ft
b = 10 ft
h = 12 ft
Now, let's plug all these into the equation:
\(A = \frac{4+10}{2} (12)\)
\(A = \frac{14}{2}(12)\) Add what's in the numerator
\(A = 7(12)\) Divide 14 by 2
A = 84 \(ft^{3}\) Multiply 7 by 12
So, the area of the trapezoid is 84 \(ft^{3}\).

Angles -
There are 3 types of angles. They are called obtuse, right, and acute angles.
Obtuse angles - Obtuse angles are angles that are more then 90 degrees. So, if you look at your options for the first question you will see that there is only one option that is more than 90 degrees. The answer would be A, 137 degrees since 137 is bigger than 90.
Right angles - Right angles are angles that are exactly 90 degrees. No less and no more. It has to be exactly 90 degrees. If you were looking for the right angle in this question the right answer would be D, 90 degrees.
Acute angles - Acute angles are angles that are strictly less than 90 degrees so anything less than 90 degrees would be called an acute angle. Some examples would be 89 degrees, 51 degrees, 1 degree. If had to choose the acute angle in this problem then the answers would be B, 87 degrees, and C, 75 degrees.

The area of the triangle below is 9/32 square centimetres. .What is the length of the base? Express your answer as a fraction in simplest form.
Answers
From the provided figure and given information,
Area or triangle = \( \sf \dfrac{9}{32}\; cm^2 \)Height of the triangle = \( \sf \dfrac{3}{4}\; cm \)We are asked to calculate the length of base.
As it we know that,
\(\\ \twoheadrightarrow\quad \bf{Area_{(\Delta)} = \dfrac{1}{2} \times b \times h}\\ \)
h denotes height b denotes baseSo,
\(\\ \twoheadrightarrow\quad \sf{\dfrac{9}{32}\; cm^2 = \dfrac{1}{2} \times b \times \dfrac{3}{4}\; cm}\\ \)
\(\\ \twoheadrightarrow\quad \sf{\dfrac{9}{32}\; cm^2 = b \times \dfrac{3}{8}\; cm}\\ \)
\(\\ \twoheadrightarrow\quad \sf{\dfrac{9}{32}\; cm^2\div \dfrac{3}{8}\; cm= b }\\ \)
\(\\ \twoheadrightarrow\quad \sf{\dfrac{\cancel{9} }{\cancel{32} }\times \dfrac{\cancel{8} }{\cancel{3}} \; cm= b }\\ \)
\(\\ \twoheadrightarrow\quad \bf \underline{ \dfrac{3}{4}\; cm= b }\\ \)
