Answer:  Check out the screenshot below for the answers

==========================================================

Explanation:

For each column, we divide the values by the sum of each column.

The sum of the first column is 6+8 = 14, and the sum of the second column is 7+3 = 10.

Column 1:

  • 6/14 = 0.43
  • 8/14 = 0.57

Those values are approximate to two decimal places.

Column 2:

  • 7/10 = 0.70
  • 3/10 = 0.30

Those values are exact.

The values in bold are then filled in the table as you see below.

A result like 0.43 means that 43% of those who play a sport also play an instrument. The other values are interpreted in a similar fashion.

Answer:

Δ HGI ≅ ΔEDF

Step-by-step explanation:

Given:

Δ DEF ≅ Δ GHI

From the given congruence statement we can figure out the corresponding sides that are congruent.

The arrangement shows:

D\rightarrow G\\E\rightarrow H\\F\rightarrow I

So the rearranged statement can be written as:

ΔEDF ≅ Δ HGI

or

∴ Δ HGI ≅ ΔEDF

Tammy will rent a car for the weekend. She can choose one of two plans. The first plan has no initial fee but costs 0.70 per mil
tensa zangetsu [6.8K]
This problem is about linear equations. We assume Dale drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=38+0.11X
Plan II: Y=49+0.07X
When both plans cost the same, 38+0.11X=49+0.07X. We will get X = 275miles, and Y=$68.25

Allison ate 7 of her 20 apples. What percent of the apples did she eat?
Brrunno [24]

Answer:

 Percentage of apples ate by Alison = 35 %

Explanation:

  Percentage of a process = (Number of process in favor / Total number of processes) x 100

  Total number of apples in the hand of Alison = 20

  Total number of apples ate by  Alison = 7

  Percentage of apples ate by Alison = ( Total number of apples ate by  Alison/Total number of apples in the hand of Alison) x 100

                                =\frac{7}{20} *100=35%

  Percentage of apples ate by Alison = 35 %

4(x+2)=36 please help
MaRussiya [10]
To solve it you have to distribute (multiply) the 4 to the x and the 2.Then you would have to subtract 8 by both sides and which it would cancel on the left side, then after you divide 4 by both sides and then u get you answer.

The sum of the digits of a two digit number is 6z the number with its digits reversed is 18 less than the original number. Find
Debora [2.8K]

Answer:

42

Step-by-step explanation:

Given:-

The Sum of the Digit of a Two Digit number is 6.

On reversing, the number is 18 less than the original number.

To Find:-

The original Number.

Let the Ones digit be "x"

ten's digit be = (6 - x)

Original Number = x + 10(6 - x) = 60 - 9x

Now, Atq.

One's Digit = (6 - x)

Ten's digit = x

New Number = 10 × x + (6 - x) = 9x + 6.

So,

(New Number) - (Original Number) = 18

(9x + 6 ) - (60- 9x) = 18

9x + 6 - 60 + 9x = 18

18x - 54 = 18

18x = 18 + 54.

18x = 72

x = 72/18

x = 4.

Therefore,

One's Digit = x = 4

Ten's digit = 6 - x = 2

Original Number = 42
