if each of the following quadrilaterals are trapezoids find the missing measures. show your work.

Answer:

1/3a - 8

Step-by-step explanation:

Distribute negative sign:

2/3a - 5 + -1 (1/3a + 3)

2/3a + -5 + -1 (1/3a) + (-1)(3)

2/3a + -5 + -1/3a + -3

Combine like terms:

2/3a + -5 + -1/3a + -3

(2/3a + -1/3a) + (-5 + -3)

= 1/3a - 8

The charity should collect 600 cans of food

Number of families that the charity asked to donate food = 150

80% of the families donated 5 cans of food

Number of families that actually donated 5 cans of food = (80/100) x 150

Number of families that actually donated 5 cans of food = 0.8 x 150

Number of families that actually donated 5 cans of food  = 120

Number of cans donated by each family = 5

Number of cans donated by 120 families = 5 x 120

Number of cans donated by 120 families = 600

The charity should collect 600 cans of food

Answer:

$84.40

Step-by-step explanation:

mowing: $9.40/hour

babysitting: $7.80/hour

4 hours mowing + 6 hours babysitting =

= 4 × $9.40 + 6 × $7.80

= $37.6 + $46.8

= $84.40

Answer:

$84.40

Step-by-step explanation:

$9.40 · 4 + $7.80 · 6 = ?

9.4 · 4 = 37.60

7.8 · 6 = 46.80

37.60 + 46.80 = $84.4

Question 1.  38.6 %   2.  61.4%

Step-by-step explanation:

(New Cost - Old Cost) ÷ old Cost × 100

    (305 - 220) ÷ 220 x 100

    =   85/220 x 100

    = 38.6 %

2.  New Cost 305 + 50 = $355    

(Now new cost - old cost) ÷ old cost ×  100

    (355 - 220)  ÷ 220 × 100  

    =  135/220 × 100

        61.4%

Answer:

252, 1 1/4, 308, 1 1/2

Step-by-step explanation:

5. The kitchen is 2 1/4 in by 1 3/4 in. 2 1/4in = 9/4in = 18ft. 1 3/4in = 7/4in = 14ft.

So we have 18ft by 14ft. The area is one side multiplied by the other side:

18 × 14 = 252ft^2.

6. 10/2 = 5. 5/4 in = 1 1/4in.

7. Bedroom 2 is 1 3/4in by 2 3/4in. 1 3/4in = 7/4in = 14ft. 2 3/4in = 11/4in = 22ft.

14ft × 22ft = 308ft^2 of carpet.

8. 12ft/2 = 6. 6/4 = 1 2/4 = 1 1/2 in.

Hope that helps!

Answer in the picture.

Answer:

To determine if the difference of two numbers is less or greater than the first number, check the value of the first number, and the value of the second number.

(greater) - (lesser) = (positive)

(lesser) - (greater) = (negative)

(neg lesser) - (neg greater) = (positive)

(neg greater) - (neg lesser) = (negative)

For Example:

10 - 5 = 5

5 - 10 = -5

(-5) - (-10) = 5

(-10) - (-5) = -5

Please correct me if I’m wrong, I may have misunderstood the question.

Answer:

∡a has a vertical angle sibling of 40°, and vertical angles are always congruent.

∡b is the 3rd angle in a triangle, the other two are 40° and 90°, recall all interior angles in a triangle add up to 180°.

∡c is a linear angle, namely an angle on the same flat-line as another, and linear angles always add up to 180°.

Total Area = 235cm^2

Step-by-step explanation:

Step 1 ) we have our lengths 11 and 20 so we need to separate the into 2 shapes  Step 2)   Label and draw new shape 20-11 = 9  to show (Shape square  1) = measuring 9 *9 and   another  (Shape Rectangle 2) = 11* 14  Step 3) Show how you do the multiplication of Square shape 9* 9 = 81cm^2  and Area Rectangle 11 * 14 = 154 cm^2   Total Area = 81+154 = 235cm^2    You can if you like in table multiplication show 11*14 by adding a zero underneath the 14 = 140 +14 = 154 then add and show +81 = 235cm^2 It is always easier to retain a shape if subtracting to get a 2nd shape this way it saves time with subtraction and in my example only needed to subtract 20-11 = 9 then 9*9 = 81cm^2 to retain the 14 *11 = 154cm^2 area for the rectangle

Answer:

Step-by-step explanation

full rectangle area (see figure) - small rectangle area
