whats the domain of y=-3x+7?

Answer:

Step-by-step explanation:

∠BEF = ∠ABE   {Alternate interior angle}

∠BEF = 60

∠EQR = ∠ BEF         {Corresponding angles}

∠EQR = 60

In ΔEQR

∠QER + ∠EQR + ∠ERQ = 180 {angle sum property}

80 + 60 +x = 180

140 + x = 180

          x = 180- 140

x = 40

Answer:

13.7

Step-by-step explanation:

The computation of the volume of toy A is shown below:

7 × k^2=9

k^2= 9 ÷ 7

k=√9 ÷ 7

k = 1.133893419

Now

= 20 ÷ 1.133893419³

=13.7

Answer:

isabel saves the most of their salary each month

Step-by-step explanation:

Let us assume the Salary of Gavin, Harry & Isabel be $100

Since

Gavin saves 28%

So his saving amount is Gavin

= 28% of $100

= $28

As harry spends 3 ÷ 4 of his salary

So Harry Spenings is

= (3  ÷ 4) of $100

= $75

Now

Harry Saving is

= $100 - $75  

= $25

Also the ratio between isabel saves, and spend is 3:7

3k + 7k = 10k = 100S

 k = $10

Now

the amount of salary isabel saves

= 3k

= 3 × $10

= $30

Now

$30 > $28 > $25

i.e.

isabel Saving >  Gavin Savings > Harry Savings

Hence, isabel saves the most of their salary each month

Answer:

CE = 36

Step-by-step explanation:

The opposite sides of a parallelogram are congruent , then

AS = CE , substitute values

2x + 10 = x + 23 ( subtract x from both sides )

x + 10 = 23 ( subtract 10 from both sides )

x = 13

Then

CE = x + 23 = 13 + 23 = 36

Answer:

[tex]1\%[/tex]

Step-by-step explanation:

Simple interest (I) = $160

Principal amount (P) = $2000

Time period (t) = 8 months

Let R denotes rate of interest.

Relation between simple interest, principal amount, time and rate of interest  is given by [tex]I=\frac{PRT}{100}[/tex]

[tex]160=\frac{2000(R)(8)}{100} \\\\160=160R\\R=1\%[/tex]

Answer:

12

Step-by-step explanation:

It would be: r = I * 100 / P * R

r = 160.67 * 100 / 2000 * 2/3

r = 16067*3 / 4000

r = 48201 / 4000

r = 12

Answer:

25.12

Step-by-step explanation:

c = 2 pi r

d = 8 so r = 4

c = 2 * 3.14 * 4

c = 25.12

Answer:

Step-by-step explanation:

Given

Diameter (d) = 8 yd

radius (r) = d/2 = 8/2 = 4

Now

Area = π * r²

        = 3.14 * 4²

        = 50.24 yd²

Circumference

= π * d

= 3.14 * 8

= 25.12 yd

Answer:

45 and 50

Step-by-step explanation:

each large square is 5 minutes.

for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)

15 x 3 = 45

for 40 < t < 60 there is two columns of 25 minutes (5 x 5)

25 x 2 = 50

From the given histogram we have the values of the empty box are 45 and 50.

We have given that,

the incomplete histogram and table give some information about the waiting time in minutes, experienced by patients at a dental surgery.

We have to complete the given table.

A histogram is an approximate representation of the distribution of numerical data. The term was first introduced by Karl Pearson.

each large square is 5 minutes.

for 0 < t < 30, there are three columns of 15 minutes ( 3 x 5)

15 x 3 = 45

for 40 < t < 60 there is two columns of 25 minutes (5 x 5)

25 x 2 = 50

Therefore the values of the empty box are 45 and 50.
