Answer:

x = 51

Step-by-step explanation:

The figure shown is a pentagon

The angles in a pentagon add up to equal 540

Which means that 77 + 107 + 156 + 149 + x = 540

^ ( note that we just created an equation that we can

use to solve for x )

We then solve for x using that equation

77 + 107 + 156 + 149 + x = 540

step 1 combine like terms

77 + 107 + 156 + 149 = 489

we now have 489 + x = 540

step 2 subtract 489 from each side

489 - 489 cancels out

540 - 489 = 51

we're left with x = 51

ivanzaharov [21]

Answer:

1a. p0= 0.714

1b The result is not reasonably close to the value of 3/4 that was expected

Step-by-step explanation:

1a.Since One sample of offspring contained 376 green peas and 150 yellow peas therefore the probability of getting an offspring pea that is green will be:

Green pea/(Green pea+ Yellow pea)

p0= 376 /(376+150)

p0=376/526

Probability of getting Green pea = 0.714

1b.The result is not reasonably close to the value of 3/4 that was expected.

The dimensions of a trapezoid are shown below. Which equation could you use to find the Area of the Trapezoid?

Contact [7]

Answer:

See Explanation

Step-by-step explanation:

No trapezoid is attached; so, I will solve on a general note

The area of a trapezoid is:

$Area = \frac{1}{2}(Sum\ of\ parallel\ sides) * Height$

Using the attached image as a point of reference;

The parallel sides are: AD (6cm) and BD (12cm)

The height is 4cm

So, the area is:

$Area = \frac{1}{2} * (6cm + 12cm) * 4cm$

$Area = 18cm * 2cm$

$Area = 36cm^2$

50 people plan to attend the dance and each person will eat 2 slices of cake. If each cake contains 20 slices, how many cakes sh

Naya [18.7K]

Answer:

Step-by-step explanation:

You multiply the number of people by the number of each slices each person gets. Which is 100; 50x2.

Each cake has 20 slices so you divide 100 by 20. Which equals 5.

It would take 5 cakes to feed all 50 people 2 slices each.

Hope this helps. :)
