Answer:

Step-by-step explanation:

Answer:  C

Step-by-step explanation:

To find the perimeter of a rectangle , you need to use the formula  

P = 2l + 2w   where   P is the perimeter, l is the length, w is the width.

Input the dimensions, for each rectangle and solve for the P

P = 2(3) + 2(9)

P = 6 + 18

P = 24  

P = 2(5) + 2(11)

P = 10 + 22

P = 32

The smaller rectangle has a perimeter of 24 and the large rectangle has a perimeter of 32

The ratio will be    32 : 24  which breaks down to  4: 3

Answer:

the answer is 36

Step-by-step explanation:

So, in order to round properly, anything under 4 goes down to zero and anything 5 or above goes UP to the nearest zero. it all depends on your desired number that you're rounding to.

EX: 69.436

hundredth place-   69.44

tenths place - 69.4

whole #-   69

hope this makes sense, youll get it eventually, i promise

Answer:

14

Step-by-step explanation:

to find area, use the equation A=ab/2

a and b are the sides given. a=7, b=4

next, plug into equation

A=7×4/2

A=14

[tex]= \color{plum}\tt(C) 7 \frac{2}{4} [/tex]

Quantity of water she needs [tex] = \tt \frac{3}{4} \: cup [/tex]

Number of servings she needs = 10

Number of cups of water she will need :

[tex] = \tt \frac{3}{4} \: \times 10[/tex]

[tex] = \tt\frac{30}{4} [/tex]

[tex] =\tt 7\frac{2}{4} \: cups[/tex]

Thus, she needs [tex] \tt 7\frac{2}{4} \: cups [/tex] of water.

Therefore, the correct option is [tex]\color{plum}\tt(C) 7 \frac{2}{4} [/tex]

Answer:

y=5/6x -3

Explanation:

first subtract -5x from both sides, then divide everything by -6, and boom you have your answer.

x = width, y = length

x = 1, y = 5

x = 2, y = 10

x = 3, y = 15

x = 4, y = 20

x = 5, y = 25

Answer:

For radio = $40.43

Television =  $444.73

Player =  $364.73

Step-by-step explanation:

The computation of the each device cost is shown below:

let us assume the following things

radio be x

television x + 10x

player x + 10x - $80

Now the equation is

x + x + 10x + x + 10x - $80 = $850

3x + 20x - $80 = $850

23x = $930

x = $40.43

For radio = $40.43

Television = $40.43 + 10(40.43)

= $40.43 + $404.3

= $444.73

and, the player would be

= $444.73 - $80

= $364.73

Yes. The first step is to set up the equations so that one unknown cancels out: here, the z's will cancel out:

5z+4y=-14

3z+6y=-6

-15z-12y=42

15z+30y=-30

8y=12

y=1.5

3z+6y=-6

3z+6(1.5)=-5-9

z=-14/3

Answer:

mode = 1

median = 2

mean = 3

Step-by-step explanation:

Here in this question, we want to calculate the given measures of central tendencies.

1. Mode

The mode refers to the number that has the highest frequency. The number here is the first number which is 1.

2. Median

This refers to the middle number after the numbers have been arranged in the descending or ascending order. Looking at the numbers, we have the middle number at the 8th term. The number at the 8th term is the number 2

3. Mean

The mean is the average of the numbers. It is calculated by summing up the numbers and dividing by the count of the numbers.

The sum of the numbers is;

1(7) + 2(3) + 3(1) + 5(2) + 8(1) + 11(1) = 45

The count of the numbers is 15

The mean is thus;

45/15 = 3

Step-by-step explanation:

45-45-90

Answer:

$478

Step-by-step explanation:

After 20 years, William will have a total of $3,513.94

After 20 years, Nolan will have a total of $3,991.93

Difference = $478

William:

2300[1 + (.02125 ÷ 4)]^4 · 20

2300 · (1 + .0053125)^80

2300(1.5278)

$3,513.94

Nolan:

2300[1 + (.0275 ÷ 12)]^12 · 20

2300 · (1 + .0023)^240

2300(1.7356)

$3,991.93

After 20 years, $478 more money would Nolan have in his account than William, to the nearest dollar.

Compound interest is when you earn interest on both the money you've saved and the interest you earn.

Formula:

A = P(1 + {r}/{n})^{n.t}

here, we have,

After 20 years, William will have a total of $3,513.94

After 20 years, Nolan will have a total of $3,991.93

Difference = $478

William:

2300[1 + (.02125 ÷ 4)]^4 · 20

=2300 · (1 + .0053125)^80

=2300(1.5278)

=$3,513.94

Nolan:

2300[1 + (.0275 ÷ 12)]^12 · 20

=2300 · (1 + .0023)^240

=2300(1.7356)

=$3,991.93

Hence, After 20 years, $478 more money would Nolan have in his account than William, to the nearest dollar.

#SPJ2

Answer:

y=6*x+101

Step-by-step explanation:

Slope intercept form is y=mx+n, where m is the slope and n is the intercept.

Substituing in that equation the two points we get two different expressions. Now we have to solve a 2x2 system of equations.

I decide to solve it through substraction (literally one expression minus the other). That way we cancel out the n and obtain the value of m.

Now that we have m we plug in the value of m in one of the expressions to obtain the value of n.

To express the final equation we just plug in the values of m and n in the expression y=mx+n!

Answer:

y=6*x+101

Step-by-step explanation:

The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
