25% there are 8 sections and there are two you are trying to land on making it 2/8=25%

what is the smallest whole number larger than the perimeter of any triangle with a side of length 5 and a side of length 15?

Pachacha [2.7K]

If it is perimeter add 15+15 and 5+5 and if it is area then just do 15 times 5 and if it is perimeter 15 plus 15 is 30 and 5 plus 5 is 10 so 30 plus 10 is 40 and if you are doing 15 times 5 is 75 depends if it is perimeter or area

What is the perimeter of rhombus WXYZ?

oksian1 [2.3K]

<u>Answer</u>:

The perimeter of rhombus WXYZ is $4 \sqrt{13}$

<u>Step-by-step explanation:</u>

Step 1 :Finding length of XY

Distance formula = $\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}$

here

$x_1$ = 5

$x_2$ =3

$y_1$ = -1

$y_2$ =2

XY = $\sqrt{(3-5)^2 +(2 -(-1))^2}$

XY = $\sqrt{(3-5)^2 +(2 +1))^2}$

XY = $\sqrt{(-2)^2 +(3))^2}$

XY = $\sqrt{4 +9}$

XY = $\sqrt{(13)}$

Step 2 :Finding length of YZ

Distance formula = $\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}$

here

$x_1$ = 3

$x_2$ =5

$y_1$ = 2

$y_2$ =5

YZ = $\sqrt{(5-3)^2 +(5-2)^2}$

YZ = $\sqrt{(2)^2 +(3)^2}$

YZ = $\sqrt{4 +9}$

YZ = $\sqrt{(13)}$

Step 3 : :Finding length of ZW

Distance formula = $\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}$

here

$x_1$ = 5

$x_2$ =7

$y_1$ = 5

$y_2$ =2

ZW = $\sqrt{(7-5)^2 +(5-2)^2}$

ZW = $\sqrt{(2)^2 +(3)^2}$

ZW = $\sqrt{4 +9}$

ZW = $\sqrt{(13)}$

Step 4 :Finding length of WX

Distance formula = $\sqrt{(x_2-x_1)^2 +(y_2-y_1)^2}$

here

$x_1$ = 7

$x_2$ =5

$y_1$ = 2

$y_2$ = -1

WX = $\sqrt{(7-5)^2 +((-1)-2)^2}$

WX = $\sqrt{(2)^2 +(-3)^2}$

WX = $\sqrt{4 +9}$

WX = $\sqrt{(13)}$

Step 5: finding the perimeter of the rhombus

Perimeter= 4 X side

=> $4 \times \sqrt{13}$

=> $4 \sqrt{13}$

A family eats dinner and the cost of the meal totals $50, before tax. The tax rate is 10% They also want to tip 20% of the bill,

Butoxors [25]

Answer:

66.00

Step-by-step explanation:

Convert 10% to a decimal by moving the point from 10. to 0.10 (back two places) and multiply it by 50 which gives you $5, which equals the tax they payed. Now they want to tip 20% of the entire bill including tax, so convert 20% to a decimal 20. to 0.20. Now multiply .20 * 55(55 is the $50 payed in meals and the $5 payed in taxes added) And you get $11 for the tip. Add 55 +11 and there's your answer

4. Mrs. Kreger created the expression

Charra [1.4K]

Here, we are required to find how many hours per week does Lindsey need to study if she wants to have an average of at least 90

Lindsey needs to study for at least 15.25 hours to have an average of 90

Given expression:

4(h + 11) – 15

Where,

h = number of hours

For Lindsay to have at least 90

4(h + 11) – 15 = 90

open parenthesis

4h + 44 - 15 = 90

4h + 29 = 90

4h = 90 - 29

4h = 61

Divide both sides by 4

h = 61/4

h = 15.25 hours

Therefore,

Lindsey needs to study for at least 15.25 hours to have an average of 90
