Answer:

7abc

24h

63gh

28fg

27deyz

Step-by-step explanation:

7∙a∙b∙c = 7abc

3h ∙ 8 = 3  ∙ 8 ∙ h = 24h

7g ∙ 9h = 7 ∙ 9 ∙ g ∙ h = 63gh

4f ∙ 7g = 4 ∙ 7 ∙ f ∙ g = 28fg

3de ∙ 9yz = 3 ∙ d ∙ e ∙ 9 ∙ y ∙ z = 3 ∙ 9 ∙ d ∙ e ∙ y ∙ z = 27deyz

Lesson Posttest
stepladder [879]

Answer:

1

Step-by-step explanation:

Probability = number of fruit type/total number of fruit. Total number of fruit = 5 + 9 + 5 = 19.

The probability of drawing an apple is P(apple) = number of apples/total number of fruit = 5/19.

The probability of drawing a peach is P(peach) = number of peaches/total number of fruit = 9/19

The probability of drawing an apple is P(orange) = number of oranges/total number of fruit = 5/19

The probability of drawing either an apple, peach or orange at the first draw of fruit from the bag is

P(apple or peach or orange) =  P(apple) + P(peach) + P(orange)

                                               = 5/19 + 9/19 + 5/19

                                               = (5 + 9 + 5)/19

                                               = 19/19

                                               = 1

Write the equation, in slope-intercept form, of a line with an undefined slope and an x-intercept of -7. Type the equation in th
quester [9]
Undefined slope

slope=rise/run
if run=0, we get an undefined slope
means that it does go left or right, only up and down
the equaiton will be x=something
x intercept is -7 so the equation is x=-7

Can u solve the answer
pickupchik [31]

Answer:

She needs 50 ft² of wood to cover the table

Step-by-step explanation:

You need to know the formula for area of a trapezoid, which is

A = (B1 + B2)h/s     (add the bases together, multiply by the height, then divide

                                by 2)

We are given B1 = 12, B2 = 8, and h = 5, so plug them in and simplify

A = (12 + 8)(5)/2

 

    A = (20)(5)/2

       A = 100/2

         A = 50 ft²
