Answer:
See below.
Step-by-step explanation:
To find the surface area, find the area of the square base and add it to the area of each triangle face. Find the area of the base by multiplying base length by base length. Find the area of each triangle face by multiplying 1/2 * b*h.
Example:
For a base which is 12 by 12. The area is 12 x 12 = 144.
For the triangle face, the area is 1/2 * 12 * 15 = 90. Since there are 4 faces, the total area is 4 * 90 = 360.
Together the surface area is 360 + 144 = 504.
Answer:
<u>Josie will earn $13.75 and her brother Sean will earn $16.25</u>
Step-by-step explanation:
Given that For every $5.50 that Josie earns, her brother earns $6.50.
Tuesday, they earned $30.00
Using the ratio and the proportional
Josie : Sean : Total
5.5 : 6.5 : 12
x : y : 30
So, x = 5.5 * 30/12 = 13.75
And y = 6.5 *30/12 = 16.25
<u>So, Josie will earn $13.75 and her brother Sean will earn $16.25</u>
Given
Gina has 6 yards of ribbon.
She cuts the ribbon into pieces that each measures three fourths yard.
Find out how many pieces of three fourths yard does Gina have
To proof
let the number of pieces of the ribbon be x.
As given in the question
Gina has of ribbon = 6 yards
She cuts the ribbon into pieces that each measures three fourths yard
Than the equation becomes


solving the above equation
we get
x = 2 × 4
x = 8
Gina have 8 pieces of three fourths yard
Hence proved
