Answer:

G:O = 3:10

the ratio of green marbles to orange marbles is 3:10

Step-by-step explanation:

Let G, Y and O represent green, yellow and orange marbles respectively.

Given;

the ratio of green marble to yellow marble is 2 : 5

G:Y = 2:5

G/Y = 2/5

the ratio of yellow arbles to orange marbles is 3 : 4

Y:O = 3:4

Y/O = 3/4

the ratio of green marbles to orange marbles G:O;

G/O = G/Y × Y/O

Substituting the values;

G/O = 2/5 × 3/4

G/O = 3/10

G:O = 3:10

the ratio of green marbles to orange marbles is 3:10

Answer:

D

Step-by-step explanation:

When we divide the entire equation by -1/2 to get rid of the coefficient of n we get n = 16.

Answer:

D.) 16

Step-by-step explanation:

Solve for n:

-n/2 = -8

Multiply both sides of -n/2 = -8 by -2:

(-2 (-n))/2 = -2 (-8)

-2×(-1)/2 = (-2 (-1))/2:

(-2 (-1))/2 n = -2 (-8)

(-2)/2 = (2 (-1))/2 = -1:

--1 n = -2 (-8)

(-1)^2 = 1:

n = -2 (-8)

-2 (-8) = 16:

Answer: n = 16

Answer: m∠1=42°

Step-by-step explanation

For this problem, we can separate the triangle into 2 separate triangles to solve for m∠1.

We know that m∠4 is 106°. ∠2 and ∠4 are supplementary angles. You can see that they make a straight line of 180°. We can use this fo find ∠2.

∠2+∠4=180

∠2+106=180

∠2=74°

Now that we know ∠2 is 74°, we can use that to solve for m∠1.

We know that the measures of the angles in a triangle equal to 180°. For the triangle at the bottom, we see ∠3, ∠2, ∠1. Since we know ∠3 and ∠2, we can find ∠1.

∠3+∠2+∠1=180

64+74+∠1=180

138+∠1=180

∠1=42°

Answer:

3600 m or 3.6 km

Step-by-step explanation:

The first thing is to take into account that the pulse rate is equal to 75 per minute, or what is the same as 75 beats per 60 seconds, then we must know how many seconds would be 15 beats:

15 beats * 60 seconds / 75 beats = 12 seconds

Therefore, we know that the velocity is equal to:

v = d / t

We know the time and the speed, therefore:

d = v * t

replacing

d = 300 * 12

d = 3600

is located at 3600 meters or 3.6 km

Answer:

1_11/20 pounds, or 1.55 pounds.

Step-by-step explanation:

Since at the beginning, he had 5 1/4 pounds and used 3/5, we subtract the amount of pounds. We are then left with 93/20 pounds, which he then splits among 3 containers. Dividing by three, we then get 31/20 pounds in one aquarium, or 1 11/20 pounds in each aquarium or 1.55 pounds.

Answer:

(7, 13/3)

Step-by-step explanation:

[tex]y=\frac{1}{3} x+2\\[/tex]   Line up the equations on top of each other

[tex]y=\frac{4}{3} x-5[/tex]

[tex]-4*[y=\frac{1}{3} x+2][/tex]   Multiply the top equation by [tex]-4[/tex] in order to cancel out the [tex]x[/tex] variable

[tex]-4y=-\frac{4}{3} x-8[/tex]   Switch out the first equation for this one

[tex]-4y=-\frac{4}{3} x-8[/tex]   Line up the equations

    [tex]y=\frac{4}{3} x-5[/tex]

[tex]-3y=-13[/tex]   Add the two equations top to bottom, left to right

    [tex]y=\frac{13}{3}[/tex]

Now that you've found [tex]y[/tex], you need to find [tex]x[/tex]. Just plug in the y-value to either of the equations in Step 1:

The first equation has smaller numbers, so let's use that one.

[tex]\frac{13}{3} =\frac{1}{3} x+2[/tex]

To make it easier you can multiply all the terms in the equation by 3:

[tex]13=x+6[/tex]

 [tex]7=x[/tex]

The [tex]x[/tex]- and [tex]y[/tex]- values together give a solution of ( [tex]7[/tex], [tex]\frac{13}{3}[/tex] )

Answer:

CD = 20 cm

Step-by-step explanation:

Area of Δ = 1/2(Base)(Height)

Where Height = 15, Area = 150

So,

150 = 1/2(CD)(15)

CD = [tex]\frac{150*2}{15}[/tex]

CD = 10*2

CD = 20 cm

Answer:

The difference between city and town is 189m.

Step-by-step explanation:

A city is 138m above sea level and town is 51m below see level.

When finding the differences, you have to take the highest value and subtract the lowest value :

[tex]138 - ( - 51) = 138 + 51 = 189m[/tex]

Answer:

This is true! 1x=1

Step-by-step explanation:

So let's rewrite the question again.

-5(x - 1) = 2x - 7x + 5

So we will solve from left to right.

-5(x-1) <- In here, we cannot add a variable to a whole number. So, we simply multiply -5 by x and -1.

-5(x - 1) = -5x+5

2x - 7x + 5 <- Here, we can subtract 2x-7x. They are both variables. But, we cannot add 5 to a variable.

2x - 7x + 5 = -5x+5

Now, here is the equation that we have so far.

-5x+5 = -5x+5

+5x        +5x

----------------------

5=5

-5 -5

0=0

So in here, we can have anything. 1, 2, 3, 4, 5, 6, 100, anything. So, the answer is:

All Real Numbers

Answer:

5 shifts

Step-by-step explanation:

The pool is open for 7 1/2 hours (15/2 hours) per day.

Each lifeguard shift lasts for 1 1/2 hours (3/2 hours).

To get the number of shifts per day, we divide the total hours that the pool is open by the time of each lifeguard shift:

[tex]\frac{15}{2} / \frac{3}{2} \\\\= \frac{15}{2} / \frac{2}{3} \\\\ = 5[/tex]

There are 5 lifeguard shifts per day.

Answer:

It will take Jake 0 hours and It will take Brianna 15 hours

Step-by-step explanation:

Let x be the no. of hours taken by Brianna to complete work alone

We are given that Jake does a job in 15 hours less time than Brianna

So,Jake work alone in hours =x-15

We are given that  they can do the job together in 10 hours

So, [tex]\frac{1}{x-15}+\frac{1}{x}=\frac{1}{10}\\\frac{x+x-15}{(x-15)x}=\frac{1}{10}\\x=3,15[/tex]

So, Brianna complete work in 15 hours

So, Jake work alone in hours =x-15=15-15=0

So, It will take Jake 0 hours and It will take Brianna 15 hours

Step-by-step explanation:

y + 5 = 3x - 18

y = 3x - 23

The solution is A

Answer:

A. y=3x-23

Step-by-step explanation:

We want to get the equation in slope intercept form, or y=mx +b, where m is the slope and b is the y intercept. Basically, we need to get y isolated.

y+5=3(x-6)

First, let’s distribute the 3 on the right side. Multiply each term inside the parentheses by the number outside the parentheses (3).

y+5=3*x + 3*-6

y+5=3x-18

5 is being added onto y. We need to perform the inverse operation to get y by itself. The opposite of addition is subtraction. Subtract 5 from both sides

y+5-5=3x-18-5

y= 3x-18-5

y=3x-23

Therefore, the correct answer is A. y=3x-23
