2.45 + 0.54 + 0.07 =

Correct! Wrong!

Explanation:
2.45 + 0.54 + 0.07 = 3.06

Which of the following represents the smallest value?

Correct! Wrong!

Explanation:
Numbers that are farther to the right of the decimal point are smaller. Since all of the numbers have three zeros in front of them (that is, they are in the ten-thousandths place), look at the first number that is not a zero. The smallest number will represent the smallest value. Since the first number in this choice is 7, the lowest number, this represents the lowest value.

5.36 - 0.78 =

Correct! Wrong!

Explanation:
5.36 - 0.78 = 4.58

Janet makes homemade dolls. Currently, she produces 23 dolls per month. If she increased her production by 18%, how many dolls would Janet produce each month?

Correct! Wrong!

Explanation:
First, calculate 18% of 23.
23 × 0.18 = 4.14
Then, add this value (the increase) to the original value of 23.
23 + 4.14 = 27.14
Rounding off, we get 27.

Two cars are side by side. One is 3.9 meters long. The other is 6% shorter. How long is the second car?

Correct! Wrong!

Explanation:
First, calculate 6% of 3.9.
3.9 × 0.06 = 0.234
Then, subtract this value (the decrease) from the original value of 3.9.
3.9 - 0.234 = 3.666 meters
Rounding off, we get 3.7 meters

A rectangle's width is 23 cm and its length is 9cm. What is its area?

Correct! Wrong!

Explanation:
The formula for the area of a rectangle is length × width.
Therefore, A = l × w
A = 9cm × 23cm
A = 207cm2

Sam's new porch is 50 square feet in size and rectangular. What is the perimeter of the porch if the length of the porch is two times the width?

Correct! Wrong!

Explanation:
The area of a rectangle is calculated using the following formula:
A=Width⋅Length
We know that L=2W and A=50 from the question. As a result, we can insert these numbers into our equation and find W:
50=W⋅L
50=W⋅2W
50=2W2
W2=25
W=5
We know that L=2W, so L=10
Perimeter =2L+2W
Perimeter =2⋅10+2⋅5
Perimeter =30

Solve for x as follows:
3(x+1) = 5(x−2)+7

Correct! Wrong!

Explanation:
The equation can be simplified as follows:
3(x+1) = 5(x−2)+7
3x+3=5x−10+7
3x+3=5x−3
We can add 3 to both sides to get the following:
3x+6=5x
We may solve for x by subtracting 3x from both sides and then dividing the resulting equation by 2:
6 = 2x
3 = x

What is the chance of choosing a man from a group of four males and eight females?

Correct! Wrong!

Explanation:
To calculate the likelihood of choosing a guy, divide the total number of males by the total number of people:
P(Male)= Number of Males⁄Total Number of People
P(Male) = 4⁄12
P(Male) = 1⁄3

If 3t - 7 = 5t, then 6t=

Correct! Wrong!

x^4 - 1 =

Correct! Wrong!

The variables x and y are directly proportional, and y = 2 when x = 3. What is the value of y when x = 9?

Correct! Wrong!

A group of 18 people ordered soup and sandwiches for lunch. Each person in the group had either one soup or one sandwich. The sandwiches cost $7.75 each and the soups cost $4.50 each. If the total cost of all 18 lunches was $113.50, how many sandwiches were ordered?

Correct! Wrong!

(3x^2 y^3 )^3 =

Correct! Wrong!

There are 3x-2 trees planted in each row of a rectangular parcel of land. If there are total of 24x-16 trees planted in the parcel , how many rows of trees are there in the parcel?

Correct! Wrong!

A ball was kicked into the air from a balcony 20 ft above the ground , and the ball's height above the ground, in feet, t seconds after the ball was kicked was h(t) = 20 - 16t^2 + 32t. What was the maximum height, in feet, of the ball above the ground after it was kicked?

Correct! Wrong!
