Terri will replace the tile and carpet in her apartment. How many total square feet of tile and carpet must Terri purchase in or

lana66690 [7]

Answer:Terry need to purchase $195\ ft^{2}$ of tile and $663\ ft^{2}$ of carpet for a total area of $858\ ft^{2}$

Step-by-step explanation:

step 1

Find the square feet of tile

The area of the tile is equal to

$A=(15)(26-13)=195\ ft^{2}$

step 2

Find the square feet of carpet

Remember that

$38\frac{1}{2}\ ft=38.5\ ft$

The area of the carpet is equal to

$A=(38.5)(26)-195-(11)(13)\\A= 1,001-195-143\\A=663\ ft^{2}$

a school netball team won ten matches , lost four and drew 1/8 of the total played . how many matches were drawn and what fracti

defon

The school net ball team drew 2 matches. The team won $\frac{5}{8}$ of total matches played

<h3><u>Solution:</u></h3>

Given, A school netball team won ten matches, lost four and drew $\frac{1}{8}$ of the total played

Let the total number of matches played be "n"

Number of matches drawn = $\frac{1}{8}$ of n

<em>Total matches played = number of won matches + number of lost matches + number of drawn matches</em>

$\begin{array}{l}{n=10+4+\frac{1}{8} n} \\\\ {n-\frac{1}{8} n=10+4}\end{array}$

Taking "n" as common from left hand side,

$\begin{array}{l}{\mathrm{n}\left(1-\frac{1}{8}\right)=14} \\\\ {\mathrm{n} \times \frac{8-1}{8} \quad 14} \\\\ {\mathrm{n} \times \frac{7}{8}=14} \\\\ {\mathrm{n}=16}\end{array}$

So, they played 16 matches in total

Number of matches drawn = $\frac{1}{8}$ of n = $\frac{1}{8} \times 16 = 2$ $\text { Fraction of won matches }=\frac{\text { number of matches won }}{\text { number of matches played }}=\frac{10}{16}=\frac{5}{8}$

$\text { Hence, the team drew } 2 \text { matches and won } \frac{5}{8} \text { of total played matches. }$

Answer:

45°

Step-by-step explanation:

This is an isosceles right triangle as two legs are congruent.

<u>The angle measure of both acute angles (B and C) is same:</u>

A.)23<br> B.)60<br> C.)53<br> D.)30

olga_2 [115]

Answer:

ABC = 30

Step-by-step explanation:

The two angles are complementary so they add to 90 degrees

2x+14 + x+7 = 90

Combine like terms

3x+21 = 90

Subtract 21 from each side

3x+21-21 = 90-21

3x = 69

Divide by 3

3x/3 = 69/3

x = 23

ABC = x+7 = 23+7 = 30
