Write the ratios 20:40:60 in its simplest form?

Answer:

£2380.23

Step-by-step explanation:

The increase will be 8.5% of £2193.76 added to £2193.76

That’s

8.5% of £2193.76

8.5% /100% x £2193.76

0.085 x £2193.76

£186.47

Increase = £2193.76 + £186.47

= £2380.23

Answer: 29

Step-by-step explanation:

23 + √36

Square root of 36 means two same numbers that will give you 36 when multiplied which is 6

23 + √36

= 23+6

= 29

Answer:

29, -17.

Step-by-step explanation:

√36 = 6 , -6

So 23 + 6 = 29 and

23 - 6 = -17.

Final answer:

By solving the system of equations step by step, we find that Erin took 18 minutes to wash the car.

Explanation:

The question involves solving a system of linear equations to find out how many minutes it took Erin to wash the car. We have two equations, x = 1/2y - 4 and x + y = 62, representing the time it took Erin (x) and Tad (y) to complete their tasks. To find the value of x, we can substitute the expression for x from the first equation into the second equation.

Let's solve the system step by step:

Finally, Erin took 18 minutes to wash the car.

Answer:

No.

Step-by-step explanation:

Given inequality:

[tex]$5h>-15; h=-5$[/tex]

[tex]5(-5)>-15\\-15>-15[/tex]

-15 is not greater than -15, it is equal.

If the inequality symbol were [tex]\leq or \geq[/tex], it would be true.

Answer:

39/160

Step-by-step explanation:

Final answer:

The experimental probability that the next person will be a woman taking the elevator up is calculated by dividing the number of women who took the elevator up (39) by the total number of people who went up (75), resulting in a simplified probability of 13/25.

Explanation:

The question asks for the experimental probability that the next person will be a woman taking the elevator up. To find this, we look at the number of women who previously took the elevator up and divide it by the total number of people taking the elevator up. In the table provided, 39 women took the elevator up, and the total number of people taking the elevator up is the sum of both men and women who did so, which is 36 (men) + 39 (women) = 75 (total).

The experimental probability is therefore calculated as follows:

Probability = Number of Women Going Up / Total Number Going Up
Probability = 39 / 75

The simplified fraction for the probability is 13/25 after dividing both the numerator and the denominator by 3.

Answer:

Perimeter is 30

Explanation:

short leg = h - 8

longer leg = h -1

(h-8)^2 + (h -1)^2 = h^2

h^2 - 16h + 64 + h^2 - 2h + 1 = h^2

h^2 - 16h + 64 + h^2 - 2h + 1 - h^2 = 0

h^2 - 18h + 65 = 0

(h  -   13 )(h    -   5  ) = 0

h-13 = 0 --->  h = 13  ---> short leg is 5 and long leg is 12 ---> perimeter is 30

h-5 = 0 ---> h = 5 --> short leg is -3 and long leg is 4 <--- disqualified because leg measure cannot be negative

short leg is 5, long leg is 12, hypotneuse is 13

5^2 + 12^2 = 25 + 144 = 169 = 13^2 <--- pythagorean check

perimeter is 5 + 12 + 13 = 30

Answer:

13

Step-by-step explanation:

5+4+3+1=13

The mileage was recorded for 13 runners.

Answer:

Width of Frame = 1.5 inches

Step-by-step explanation:

The area of the picture is 4 by 6, or

4 * 6 = 24

The frame is same width all sides, let that width of frame each side be "x".

So,

Width of frame (and pic) = 4 + x + x = 4 + 2x

Height of frame (and pic) = 6 + x + x = 6 + 2x

Total area of frame and pic is 63, so we can write:

[tex](4+2x)(6+2x)=63[/tex]

Now, we multiply and solve for "x":

[tex](4+2x)(6+2x)=63\\24+8x+12x+4x^2=63\\4x^2+20x+24=63\\4x^2+20x-39=0\\x=-6.5,1.5[/tex]

We disregard -6.5 since width can't be negative. So, we conclude:

Width of Frame = 1.5 inches

Answer:

1.5 is right

Work Shown:

cos(angle) = adjacent/hypotenuse

cos(20) = x/11

11*cos(20) = x

x = 11*cos(20)

x = 10.336618828645

x = 10.3

Step-by-step explanation:

adding a positive will lower the negative number

Answer:

monomial

Step-by-step explanation:

If it's on the Cartesian plane, you find the difference between the x coordinates (let's call that value a), and you find the difference between the y coordinates (let's call that value b)

You square a and b, and add them together (to get [tex]a^2 + b^2[/tex])

You find the square root of the sum you attained and get:

[tex]\sqrt{a^2 + b^2}[/tex]= EF

Answer:

$229

Step-by-step explanation:

Pay check = P

so

Total spent movie  T = $13.74

T = 0.4 *0.15* P = $13.74

The 40% on the Movie Theatre spending is part of the 15% spending at the mall.

So 40% of 15% of the Pay Check = $13.74

P = $13.74 / (0.4*0.15)  =  34.35/0.15 = 229

Answer:

A:

The perimeter of the parking lot is 302 yards.

The area of the parking lot is 5,544 yards squared.

B: Perimeter

C: Area

Step-by-step explanation:

A:

To find the perimeter of the parking lot, we add all the sides up. 2L + 2W = Perimeter.

2(63) + 2 (88) = 302

To find the area, we multiply the length by the width. 63 × 88 = 5,544.

B: We need to know the amount of chain needed to surround the parking lot. In other words, we need to line the perimeter with a chain.

C: We would be paving the entire area of the parking lot.

Answer:

- the value of 3.915 is the initial number of water lilies

- it is approximately 4, which matches the data

- the value 1.106 is the growth rate

- the rate represents growth for each day

- the percentage growth each day is 10.6%

The value of 3.915 is the initial number of water lilies and the value of 1.106 is the growth rate.

A regression line is a graph that illustrates the pattern of a group of statistics. In other words, it shows the data's best pattern.

We have a regression line:

y = 3.915(1.106)×

Plug x = 0

y = 3.915

The value of 3.915 is the initial number of water lilies

The value of 1.106 is the growth rate and the rate represents growth for each day.

Thus, the value of 3.915 is the initial number of water lilies and the value of 1.106 is the growth rate.

61.68

Step-by-step explanation:

Answer:

the solution to the problem is that Frannie listened to  1/6 of her entire music collection while on vacation.

Step-by-step explanation:

Fraction of the music collection on the MP3 player: 1/3

​

Fraction of the music on the MP3 player listened to: 1/2

​

Fraction of the entire music collection listened to: 1/6

​

Frannie listened to [tex]\(\frac{1}{6}\)[/tex] of her music collection while on vacation.

To solve this problem, we need to calculate the fraction of Frannie's total music collection that she listened to on vacation.

Firstly, Frannie put [tex]\(\frac{1}{3}\)[/tex] of her music collection onto her mp3 player. This means that the music on the mp3 player represents [tex]\(\frac{1}{3}\)[/tex] of the whole collection.

While on vacation, she listened to [tex]\(\frac{1}{2}\)[/tex] of the music on the player. So, she listened to [tex]\(\frac{1}{2}\) of \(\frac{1}{3}\)[/tex] of her total collection.

To find out how much of the entire collection this is, we multiply the two fractions together:

[tex]\[ \frac{1}{2} \times \frac{1}{3} = \frac{1}{6} \][/tex]

This multiplication is justified because she listened to half of a third of her collection, which is the same as saying she listened to a sixth of her collection.

Therefore, Frannie listened to [tex]\(\frac{1}{6}\)[/tex] of her music collection while on vacation."
