She spent $10.50 on all bags of candy

Answer:

$10.50

Step-by-step explanation:

So we know that Olivia not only bought 7 bags of candy but that each bag of candy costs $1.50 :

With this information, we can multiply the cost of the bags by the amount Olivia bought, therefore :

[tex]7 * 1.50[/tex]

[tex]= 10.5[/tex]

This means that the amount Olivia bought was $10.50

Answer:

I believe x = 34

Step-by-step explanation:

3 × 34 = 102

102 - 6 = 96

2 × 34 = 68

96 + 68 + 88 + 108 = 360

complimentary angles equal 90 degrees so 1 and 2, 3 and 4, 9 and 10, 11 and 12 would be complimentary

supplementary angles equal 180 degrees so 6 and 5, 5 and 7, 7 and 8, and 8 and 6 would be supplementary

First, a complementary angle are two angles that add up to 90. while supplementary add up to 180.

Complementary angles; 1 & 2, 3 & 4, 9 & 10, 11 & 12. (these all make one line which equals 180.)

Supplementary angles; 7 & 8, 5 & 7, 6 & 5, 8 & 6. (these all make up a 90 degree angle.)

Marbles:

5 red

4 yellow

Total marbles = 5 + 3 + 4 = 12.  

The probability of picking a green marble is 3/12, since there are 3 green marbles possible to grab and 12 total.  3/12 can be reduced to 1/4, or .25.  Devon has a 25% chance of picking a green marble.

Answer:

[tex]y = -\frac{1}{4}x - 2[/tex]

Step-by-step explanation:

i'm not sure if you're trying to find the equation of the line ?? but i'll assume that's the case and find the slope-intercept form equation of the line.

slope intercept form is [tex]y = mx + b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. since the slope is already identified, you can plug in [tex]-\frac{1}{4}[/tex] for [tex]m[/tex].

plug in the [tex]x[/tex] and [tex]y[/tex] values from the coordinate pair that passes through the line, which is (-4, -1). you can start with either [tex]x[/tex] or [tex]y[/tex], but i'm going to start with [tex]x[/tex].

first, plug in [tex]-4[/tex] for [tex]x[/tex].

now plug in [tex]-1[/tex] for [tex]y[/tex].

after plugging in all of the given values, the equation is now [tex]-1 = -\frac{1}{4}(-4)+b[/tex], in which you need to solve for [tex]b[/tex].

now it's time to solve! begin by multiplying [tex]-\frac{1}{4}(-4)[/tex] in order to simplify the right side of the equation.

you now have [tex]-1 = 1 + b[/tex]. subtract 1 from both sides of the equation. on the right side, it cancels itself out, leaving you with [tex]b[/tex]. on the left side of the equation, you now have [tex]-1 - 1[/tex], which equals [tex]-2[/tex].

therefore [tex]-2 = b[/tex], or [tex]b = -2[/tex].

now that you've solved for your [tex]b[/tex] value, plug it into your initial slope-intercept form equation!

if you want to check to make sure that the values are correct, plug (-4, -1) into your completed slope-intercept form equation. as you did in the beginning, plug in [tex]-4[/tex] for [tex]x[/tex] and [tex]-1[/tex] for [tex]y[/tex].

begin simplifying by multiplying [tex]-\frac{1}{4}(-4)[/tex].

subtract [tex]1 - 2[/tex].

since both sides of the equation are equal, that means your [tex]b[/tex] value of [tex]-2[/tex] is correct because it makes the equation true!

aaaand there you go! i hope this helps. have a great day! <3

Step-by-step explanation:

Given:

The equation is

[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]

To find:

The value of [tex]b^2[/tex].

Solution:

We have,

[tex]\dfrac{a}{b}=\dfrac{b}{c}[/tex]

On cross multiplication, we get

[tex]a\times c=b\times b[/tex]

[tex]ac=b^2[/tex]

[tex]b^2=ac[/tex]

Therefore, the value of [tex]b^2[/tex] is [tex]ac[/tex].

Answer:

x = 36

Step-by-step explanation:

Length of a rectangle, x+7

Width = 3

Area of the rectangle, A = 129 units²

The area of a rectangle is given by :

A = lb

So,

[tex](x+7)\times 3=129\\\\(x+7)=43\\\\x=43-7\\\\x=36[/tex]

So, the value of x is equal to 36.

Answer:

$10.5

Step-by-step explanation:

Given data

P=$150

T= 1year

R= 7%

The simple interest formula will give the accurate amount at the end of each year

A=P(1+rt)

A=150(1+0.07*1)

A=150*1.07

A=$160.5

The withdrawal = 160.5-150= $10.5

Hence the  withdrawal will be  $10.5

Answer:

whats the question? I don't see anything.

there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6.

What is the combination?

In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.

There are a total of 6 players in the round-robin racquetball tournament, which means that each player will play a set against each of the other 5 players.

To determine the total number of sets that need to be played, we can use the combination formula:

nC₂ = (n*(n-1))/2

where n is the number of players.

In this case, n = 6, so:

6C₂ = (6*(6-1))/2 = 15

Hence, there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6:
