Answer:
7. 86.25 8. 18.75
Step-by-step explanation:
Answer:
7. Answer is 1236.25$
8. Answer is 143.75$
9. Answer is 16.485$
10. Answer is 6.825$
11. Answer is 31.25%
12. Answer is 0.125 for the decimal section and 12.5% for the percent section.
Step-by-step explanation:
7. 7.5 percent of 1150 is 86.25 and 86.25 + 1150 is 1236.25.
8. 15 percent of 125 is 18.75 therefore 125 + 18.75 is equal to 143.75.
9. 3.50 + 2.25 + 9.95 + 15.7 and 5 percent of 15.7 is 0.785 and 15.7 + 0.785 is 16.485.
10. 4.25 plus 2.25 is 6.50 and 5% of 6.50 is 0.325 and 6.50 plus 3.25 is 6.825.
11. 63 plus 25 is 88 so 88 is 68.75 percent of 128 and 100 minus 68.75 is 31.25 so 31.25 is the answer.
12. 1/8 is 12.5 percent so for the percent section it is 12.5 and for the decimal section 0.125

change the inequality sign]
or, 2m>14

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
Answers
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Step-by-step explanation:
Corresponding angles are angles that you can follow down the transversal and they will land in the same spot on the other parallel line. Look at angle 8. It is the bottom left angle in the group of 4 angles around it. If you slide it to the left it would land right on top of angle 4 which is also in the bottom left of its group of 4 angles.
You can do the same thing taking angle 8 down to angle 12.

The length of the line segment QU diagram containing three right triangles is 3 centimeters.
How find a missing length in a triangle system by similarity propertiesIn the figure given below we have a system of three distinct right triangles connected by three colinear segments. Given that the three triangles are similar, we can make of geometry properties for similarity to determine the length of the missing line segment.
In this question we must find a missing length by similarity properties, which is represented mathematically by proportions. From the figure we have the following relationship:
5/y = (5 - x)/(5 - y) = x/1 (1)
From (1) we have the following two formulas:
x = 5/y (2)
x = (5 - x)/(5-y) (3)

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

The weight of Micheal's and Brittney's new puppies are shown in the table and graph. Whose dog gains more weight more quickly? Explain.
Answers
Answer:
Brittney's Puppy
Step-by-step explanation:
Michael's puppy gains 8.6 pounds in 1 month while Brittney's puppy gains 155 ounces in 1 month
Rate of increase in weight of Micheal's puppy is less than Rate of increase in weight of Brittney's, Brittney's puppy gains weight more quickly.
What is rate of change?Rate of change is the measure of how one quantity changes in respect to change in another quantity .
let when a quantity x changes from x₁ to x₂ then the quantity y changes with respect to x from y₁ to y₂
The Rate of Change of y w. r. t. x = ( y₂ - y₁ )/ ( x₂ - x₁)
For Micheal's puppy
Rate of change in weight when age is increased from 1 to 2 months = (17.2-8.6)/(2-1)=8.6 pounds per month
Rate of change in weight when age is increased from 2 to 3 months = (25.8-17.2)/(3-2)=8.6 pounds per month
∴ Rate of increase in weight of Micheal's puppy with age is 8.6 pounds per month
For Brittney's puppy
From graph it can be seen than
At age = 1 month , weight = 155 ounces = 9.6875 pounds
At age = 2 month , weight = 310 ounces = 19.375 pounds
At age = 3 month , weight = 465 ounces = 29.0625 pounds
Rate of change in weight when age is increased from 1 to 2 months = (19.375-9.6875)/(2-1)= 9.6875 pounds per month
Rate of change in weight when age is increased from 2 to 3 months = (29.0625-19.375)/(3-2)=9.6875 pounds per month
∴ Rate of increase in weight of Brittney's puppy with age is 9.6875 pounds per month
Thus rate of increase of weight is more for Brittney's puppy.
Therefore, Brittney's puppy gains more quickly weight.
