Question

One angle of a pair of complementary angles is given which is 45Â°

Solution 1

Hey there!

The correct answer would be 45.

A complementary angle always equals 90 degrees so 90 - 45 = 45. There for the missing angle is 45.

Hope this helps!

The correct answer would be 45.

A complementary angle always equals 90 degrees so 90 - 45 = 45. There for the missing angle is 45.

Question

3 times as much as the sum of 3/4 and 2/6

Solution 1

The **result** of *3 times as much as the sum of 3/4 and 2/6** *is; **1****3****/****4**

First, we must evaluate the sum of **3**/4 and **2/6**; we have;

- 3/4 + 2/6

Using the lowest common multiple; **12**

We** **have; (9 +4)/12 = **13/12****.**

Therefore, 3 times 13/12 = 39/12 = **13/4**

Solution 2

3.25 is your answer. First, I added 3/4 and 2/6 and then I multiplied the sum by 3.

Question

A number tripled and tripled again is 891 what is the number?

Solution 1

Let the number be x.

Tripled the number = 3x

Tripled the number again = 9x

9x = 891

x = 99

**Answer: 99**

Tripled the number = 3x

Tripled the number again = 9x

9x = 891

x = 99

Solution 2

The number that is tripled and tripled again to get 891 would be 99 because 99

Question

Zachary used the calculations shown to find how much he would spend on 16 ounces of pistachios. 6 ounces of pistachios cost $7.50 mc022-1.jpg Unit price = $0.80 per ounce mc022-2.jpg What was his first error? The price per ounce should have been $45.00 per ounce. The price per ounce should have been $1.25 per ounce. The final cost should have been $20.00. The final cost should have been $16.80.

Solution 1

The price per ounce should have been 1.25 per ounce

Solution 2

**Answer: B**

**Step-by-step explanation: The price per ounce should have been $1.25 per ounce.**

Question

Grace has one $10 bill and three $5 bills she spends 9.30 on a belt and $4.20 on snack how much money does grace have left

Solution 1

Total amount = 1 x 10 + 3 x 5 = $25

Amount spent = $9.30 + $4.20 = $13.50

Amount left = $25 - $13.50 = $11.50

**Answer: $11.50**

Amount spent = $9.30 + $4.20 = $13.50

Amount left = $25 - $13.50 = $11.50

Solution 2

The correct answer is 11.50. 25-9.30-4.20=

11.50

Question

What is the following product of sqrt 10 times sqrt 10

Solution 1

Whenever we have been given to find the product of two square roots, the two roots cancel out each other. This is because

The power of two and the square root cancel out each other

In the given problem we have to multiply the square root 10 by itself, we have

Now, the next step will be

Now the square root and the power of 2 cancel each other an d the result will be 10

**Answer : 10**

Solution 2

Question

A ball is thrown upward from the top of a building. The function below shows the height of the ball in relation to sea level, f(t), in feet, at different times, t, in seconds: f(t) = âˆ’16t2 + 48t + 100
The average rate of change of f(t) from t = 3 seconds to t = 5 seconds is _____ feet per second.

Solution 1

Given that a ball which has been thrown up can be modeled by the function:

f(t)=-16t^2+48t+100

the rate of change will be:

f'(t)=-32t+48

thus:

when t=3

f(3)=-32(3)+48=-48

when t=5

f(5)=-32(5)+48=-112

thus the rate of change will be:

[f(5)-f(3)]/(5-3)

=(-112-(-48))/(5-3)

=(-64/2)

=-32 ft/sec

f(t)=-16t^2+48t+100

the rate of change will be:

f'(t)=-32t+48

thus:

when t=3

f(3)=-32(3)+48=-48

when t=5

f(5)=-32(5)+48=-112

thus the rate of change will be:

[f(5)-f(3)]/(5-3)

=(-112-(-48))/(5-3)

=(-64/2)

=-32 ft/sec

Question

The value of (a-1)+a^2-b^2/1-ab+2(a-b)/2b when a=2 and b=-1 is ?

Solution 1

The value of (a-1)+a^2-b^2/1-ab+2(a-b)/2b when a=2 and b=-1 will be evaluated as follows:

substituting the values in the expression we obtain:

(2-1)+2^2-(-1)^2/1-(2*(-1))+2(2-(-1))/(2(-1))

simplifying the above we get:

1+4-1/1-(-2)+2(2+1)/(-2)

=1+4-1+2(3)/(-2)

=1+4-1-3

=5-4

=1

Answer: 1

substituting the values in the expression we obtain:

(2-1)+2^2-(-1)^2/1-(2*(-1))+2(2-(-1))/(2(-1))

simplifying the above we get:

1+4-1/1-(-2)+2(2+1)/(-2)

=1+4-1+2(3)/(-2)

=1+4-1-3

=5-4

=1
