Scott wants to cover his patio with concrete pavers. If the patio is shaped like a trapezoid whose bases are 11 feet and 13 feet

GenaCL600 [577]

Answer:

Scott will need 168 ft² of pavers to cover his patio

Explanation:

Scott wants to cover a trapezoid-shaped patio

This means that:

To get the number of square feet of pavers he'll need, we need to get the area of his patio

Area of trapezium id calculated as follows:

$Area = \frac{base_{1}+base_{2}}{2} * height$

We are given that:

base₁ = 11 ft

base₂ = 13 ft

height = 14 ft

We now substitute with the givens to get the area as follows:

$Area = \frac{11+13}{2} * 14 = 168ft^2$

This means that:

Scott will need 168 ft² of pavers to cover his patio

Hope this helps :)

Add. 4.29 + 97.2 + 0.687 = 102.177 140.787 1,407.87 1,021.77

nordsb [41]

4.29 + 97.2 + 0.687 = 102.177

In adding decimal numbers, make sure that the decimal points are aligned. Since each number has different counts of numbers after the decimal point, use 0 to pad the missing places.

4.290
97.200
 0.687
 102.177

The count of numbers after the decimal point is the same count of number of the decimal who has the greatest count of number after the decimal point.

4.29 only has 2 counts of places after the decimal point
97.2 only has 1 count of place after the decimal point
0.687 has 3 counts of places after the decimal point.

The sum of the decimals must also have 3 counts of places after the decimal point.

in preparation for a party, brant is putting desserts onto platters. the chocolate cake is cut into 15 pieces and the cheesecake

marishachu [46]

Answer:

The greatest number of platters he can prepare is 3.

Step-by-step explanation:

Given : In preparation for a party, brant is putting desserts onto platters. the chocolate cake is cut into 15 pieces and the cheesecake is cut into 6 pieces. if he wants to prepare identical platters without having any cake left over.

To find : What is the greatest number of platters he can prepare?

Solution :

The greatest number of platters he can prepare is given by finding the GCF of 15 and 6.

Factoring the numbers,

$6=2\times 3$

$15=3\times 5$

The GCF is the greatest common factor.

$GCF(6,15)=3$

Therefore, the greatest number of platters he can prepare is 3.
