706.5

1000-706.5=293.5 cm²

Answer:

the answer is 30,20,35 in that order

Step-by-step explanation:

Step-by-step explanation:

y=mx +b

b= 5

12.5= 10m+5

10m = 7.5

m= 0.75

y=0.75x +5

..........

at x= 20 , y= 20

at y= 27.5 , x= 30

at x= 40 , y= 35

Answer: the least number of deliveries that Ben must make is 14.

Step-by-step explanation:  Given that Ben earns $9 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday.

We are to find the least number of deliveries he must make to reach his goal.

Let x be the least number of deliveries that Ben must make to reach his goal.

Then, according to the given information, we have

Thus, the least number of deliveries that Ben must make is 14.

Answer:

f = 5/4

Step-by-step explanation:

f/2 = 5/8

Multiply both sides by 2.

f = 10/8 = 5/4

Answer:

f=1.25

Step-by-step explanation:

f/2=5/8

To get 8, you must multiply 2 by 4.

So

You must do the same to the numerators -

4 times x = 5

5/4=1.25

Answer:

choice 2) x = 60°

Step-by-step explanation:

the complement of an angle is an angle that when added to the original angle = 90°

so:

x + 0.5x = 90°

1.5x = 90°

x = 90/1.5 = 60°

Answer:

X > (whatever the symbol is) 0

The figure can be composed in to one triangle and one rectangle and the area is 30 square feet.

Area of a two dimensional shape is the total region which is bounded by the object's shape.

Given is a figure.

We can divide the figure in to one triangle and one rectangle by drawing a vertical line.

Area of a rectangle = Length × Width

Here, length = 8 feet and width = 3 feet

Area of rectangle = 8 × 3 = 24 feet²

Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height

Base = 12 - 8 = 4 feet and height = 3 feet

Area of triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 feet²

Total area = 24 feet² + 6 feet² = 30 feet²

Hence the area is 30 feet².

Answer:

C

Step-by-step explanation:

If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.

A 4 + 3 ≥ 1   True, it's greater, but it can't be equal to.

B 3(4) ≥ 1     It's greater once again, can't be equal to.

C 4 - 3 ≥ 1     If x can also be greater than 4, then it works both ways. Equal and greater than.

Answer:

D is correct

Step-by-step explanation:

The opposite of a negative number is the positive version of it which is 3.5 and the absolute value of a number is always the positive version of a number which would make it also 3.5.  For example absolute value of -4 is 4 and absolute value of 5 is 5.

The data that is true is:

The range is 14.

Option C is the correct answer.

The range is the difference between the highest value and the lowest value of a given set of data.

We have,

The range of a set of data is the difference between the maximum and minimum values in the set.

In this case, the extreme values are 5 and 19, so the range would be:

19 - 5 = 14.

Therefore,

The correct statement is "The range is 14".

                B" (4, 6)

                C" (4, 2)

                D" (10, 2)          

Step-by-step explanation:

A(−5,3),B(−2,3),C(−2,1),D(−5,1)

To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:

                   A' (5, 3)

                  B' (2, 3)

                  C' (2, 1)

                  D' (5, 1)

To dialate by a scale factor of 2 you multiple everything by 2 and you should get:           A"(10, 6)

               B" (4, 6)

               C" (4, 2)
