Mathematics
1 answer:
Advocard [28]3 years ago
8 0

Answer:

148.5 sq. ft.

Step-by-step explanation:

Since Jan wants to lay sod on it, Sod required will be equal to area of the lot.

Lot is in trapezium shape

area of trapezium is given by = 1/2(sum of parallel sides) height

parallel sides has length 15 and 18 feet

sum of parallel sides = (15+18) = 33

height = 9 feet

thus area of lot = 1/2(33)9 = 148.5

Thus, Jan will need 148.5 sq. ft of sod.

What’s the answer to 3\4(8x + 12) = 3
Artemon [7]

Answer:

x = - 1

Step-by-step explanation:

\frac{3}{4} (8x + 12) = 3 ( multiply both sides by 4 to clear the fraction )

3(8x + 12) = 12 ( divide both sides by 3 )

8x + 12 = 4 ( subtract 12 from both sides )

8x = - 8 ( divide both sides by 8 )

x = - 1

In a certain Algebra 2 class of 29 students, 7 of them play basketball and 14 of them
Mariulka [41]

Answer:

<em>Two possible answers below</em>

Step-by-step explanation:

<u>Probability and Sets</u>

We are given two sets: Students that play basketball and students that play baseball.

It's given there are 29 students in certain Algebra 2 class, 10 of which don't play any of the mentioned sports.

This leaves only 29-10=19 players of either baseball, basketball, or both sports. If one student is randomly selected, then the propability that they play basketball or baseball is:

\displaystyle P=\frac{19}{29}

P = 0.66

Note: if we are to calculate the probability to choose one student who plays only one of the sports, then we proceed as follows:

We also know 7 students play basketball and 14 play baseball. Since 14+7 =21, the difference of 21-19=2 students corresponds to those who play both sports.

Thus, there 19-2=17 students who play only one of the sports. The probability is:

\displaystyle P=\frac{17}{29}

P = 0.59

Anyone help me please,find the area of each figure.​
Morgarella [4.7K]

Hey there! :)

Answer:

170 cm².

Step-by-step explanation:

This is an example of a composite figure, so find the areas of each shape separately:

Begin by finding the area of the smaller square. A = s²

A = 7² = 49 cm².

Find the area of the larger square:

A = 11² = 121 cm².

Add up the two areas:

49 + 121 = 170 cm².
