Which equation represents this situation?

Charlie worked 1.5 hours less than Dirk. Together, they worked a total of 25 hours. Dirk worked h hours.

A. h + (h + 1.5) = 25
B. h − 1.5 = 25
C. h + (h − 1.5) = 25
D. h − 2.5 = 25

Answers

Answer 1

Answer:

A. h+(h+1.5)=25

Step-by-step explanation:

I just answered another question like this, I don't understand how i explain but hope this helps :)

Answer 2
C. h+ (h-1.5)=25

h-1.5 would equal 1.5 hours LESS than what Dirk worked. Add that to h, or the number of hours Dirk worked, and that would equal 25.

An image of a rocket is shown. The rocket is made up of a triangle, a rectangle, and a trapezoid. The triangle at the top of the rocket has a base of length 3 inches and a height of 4 inches. The rectangle in the middle of the rocket has a height of 10 inches and a length of 3 inches. The trapezoid at the bottom of the rocket has one base of length 3 inches at the top, another base of length 5 inches at the bottom, and a height of 2 inches.

Answers

Answer

the area of the entire rocket is  44

area of the triangle=6

area of the rectangle=30

area of the trapezoid=8

Step-by-step explanation:

triangle= bxh/2 so 4x3= 12/2= 6

rectangle= bxh so 3x10=30

trapizoid= A=a+b2h so 3+5= 8/2= 4x2= 8

6+30+8=44

This table shows a linear relationship. x: 6 12 18 24 30 y: 252 504 756 1008 1260 Based on the information in this table, which equation can be used to model the relationship between x and y​

Answers

Answer:

The difference between value of y at x=11 is 385, the correct option is third.

Step-by-step explanation:

The difference between value of y at x=11 is 385, the correct option is third.

The equation of a line which passing through two points is given below,

The two points from the table are (3,240) and (4,320), the equation is,

Put x=11

Therefore according to the table the value of y is 880 at x=11.

The two points from the table are (2,90) and (4,180), the equation is,

Put x=11,

Therefore according to the table the value of y is 495 at x=11.

The difference between the values of y at x=11 is,

Therefore third option is correct.

Answer:

1st is 30 and 16. 2nd is reduction. 3rd is scale factor of 2/3

Step-by-step explanation:

#1 you dilate by a scale factor of 2 so you just multiply all the sides by 2 to get your answer. 15x2=30 and 8x2= 16.

#2 it is a reduction because m', s', and v' are smaller then m, s, and v

#3 the scale factor is 2/3 because you do the image over the pre-image so -2,2 / -3,3 is 2/3 same is 4,2 / 6,3 and 2,-2 / 3, -3

Answer:

6.32[tex]cm^{2}[/tex]

Step-by-step explanation:

The area of a triangle is the base multiplied by the height, divided by 2. So take the base of 8 cm, then multiply by the height of 1.58 cm, and divide by 2.

[tex]\frac{8*1.58}{2} =6.32 cm^2[/tex]

Answer:

Area = 632mm^2

Step-by-step explanation:

Area of a triangle is

1/2 × base × height

OR

= (base × height)/2

There is a tiny trick tho' because the measurement is given in cm but they asked for the answer in mm. Well, there are 10 millimeters in a centimeter.

So the base given as 8cm is 80mm. And the height given 1.58cm is 15.8mm

Area = 1/2(80)(15.8)

= 40(15.8)

= 632 mm^2
