Ciara brought $240 to spend on gifts for her family. She found 8 identical statues at a gift shop. She had $72 leftover. How much did each statue cost?

Answers

each statue costed 21 dollars
Hello! In order to solve this problem, first, you have to subtract the 72 dollars she didn’t spend on statues from 240. 240 - 72 = 168. That’s $168 she spent on statues. She bought 8 of them. Now, divide the total cost by 8. 168/8 = 21. There. Each statue Ciara bought costed $21.

for a class gardening project 1/3 of mrs gordon's students planted marigolds and 1/2 planted tulips what fraction of the class planted either marigolds or tulips

Answers

Get them to have a common denominator so you can add them
(1/3)×2= 2/6 and (1/2)×3= 3/6
Add them together
(2/6)+ (3/6)= 5/6
So 5/6 of the class planted either marigolds or tulips and 1/6 of the class planted neither

Dominique used the inequality below to find the maximum number of sweatshirts she could purchase with her savings.

32 x < 300

What is the greatest number of sweatshirts Dominique can purchase?

Answers

We just have to find the closest number that can be multiplied by 32 and still be under 300. Do this by following this step:

Divide by 32 on both sides.

x < 9.375

We can't buy 9.375 sweatshirts though, and we can't add more decimals or it will go over 300, so you round down to 9.

Dominique can buy 9 sweatshirts without going over $300!

Walter is mixing cement for his new patio. He knows he needs to water-to-cement ratio of 20-30. What percent of his total mixture is water?

Answers

The ratio of water to cement is 20:30 meaning that for every 20 parts of water, we have 30 parts of cement. There are 20+30 = 50 parts total.

Divide the number of parts of water (20) over the total number of parts (50)
20/50 = 2/5 = 0.40
use a calculator or long division to find the decimal form of 2/5 to be 0.40

Then move the decimal point 2 spots to the right to go from 0.40 to 40%

Answer: the percent of water in the mix is 40%

Final answer:

To find the percentage of water in Walter's mixture with a water-to-cement ratio of 20-30, the water part is 20 out of 50 total parts, which equates to 40% of the mixture being water.

Explanation:

Walter needs a water-to-cement ratio of 20-30 for his patio cement mixture. To find out what percent of his total mixture is water, we can interpret the ratio as a fraction and then convert that fraction to a percentage. The fraction for water is 20 parts out of a total of 20 (water) + 30 (cement) parts, which is 20/50. To convert this to a percentage, we multiply by 100%.

Calculating the percentage: (20/50) × 100% = 40%

Therefore, 40% of Walter's total mixture is water.

if h(x)=3^x-7 find h(4) show all work
[tex]h(x) = {3}^{x} - 7[/tex]

Answers

Just substitute 4 for x in the given equation:

h(4) = 3^4 - 7 = 81 - 7 = 74 (answer)
h(x) = (3^x) - 7
h(4) = (3^4) - 7 ... replace every x with 4; then use PEMDAS to simplify
h(4) = 81 - 7 
h(4) = 74

Answer: 74

Side Note: 3^4 means we have four copies of '3' being multiplied together
3^4 = 3*3*3*3 = 9*9 = 81

Prove that triangle ABC must be isosceles

Answers

First let us determine what <ABD is: 180º- 90º - 2nº = 90-2nº (the square represents a 90º angle

Then find <DCB: 180º - 90º - nº = 90-nº

Angle <ACB doesn't change: it is 90-n

but, <ABD is only part of <ABC: if we add <ABD with <DBC then we get 90-2n+n = 90-n

Definition of an isoceles triangle: It has two sides that are congruent or has two angles that are congruent.

Because both <ABC and <ACB equal 90-n the triangle ABC is an isoceles triangle.

find an equivalent expression to 3 (4m-2)-2(m+5). write your answer as an expression with two terms

Answers

12m-6-2m+10 (10m+4) is the simplest it can go

Answer:

10m - 16

Step-by-step explanation:

3 (4m-2) -2(m+5)

The equivalent expression can be simplified as an expression with two terms as follows:

3 (4m-2) -2(m+5)

Open each parenthesis by multiplying the outside value with the values in the parenthesis.

3 (4m-2) = 12m - 6

-2(m + 5) = -2m -10

Bring the value together

12m - 6 -2m  - 10

collecting like terms

12m -2m - 6 - 10

10m - 16

write a linear equation that is parallel to 12x+3y=24 and passes through the point (-2,7)

Answers

In order to write the formula for another line which is parallel, we need the slope (m). Parallel lines never in fact touch or intersect at any one point. They are either the same lines, occupying the same points, or different parallel lines, never occupying the same points, but sharing the same slope (m).
If we put out equation in slope-intercept format: y = mx+b, we can obtain our needed m.
12x+3y=24 ->> 3y = -12x+24
3y/3 = (-12x+24)/3 ->> y = -4x+8, therefore our m = -4
Now we can use our info to make the line in point-slope format: y-y1 = m (x-x1)
So, y-7 = -4 (x--2) or y-7 = -4 (x+2)
You can leave it like that or convert it:
y-7 = -4x -8 ->> y = -4x -8+7 ->> y = -4x-1
or even in this format: 4x+y=-1

The football team lost 4 yards on 2 plays in a row. Which of the following could represent the change in field position?

Answers

Lost (⬅key word) 4 is equal to -4
On 2 plays that is times 2

A negative times a positive is negative
-4×2= -8
Hope this helped you☺
Final answer:

The football team lost 4 yards on 2 plays in a row, resulting in a change in field position of -8 yards.

Explanation:

The football team lost 4 yards on 2 plays in a row. To determine the change in field position, we need to subtract the total yardage lost from the starting field position. Assuming the starting field position was at the 50-yard line, the change in field position would be -4 yards x 2 plays = -8 yards. Since the team lost yardage, the change in field position would be a negative value.

Evaluate 3x + y when x = 1/3 and y = -7/4

Write the answer in simplest form

Answers

Given:
3x + y
Substitute the variables for x = 1/3 and y = -7/4:
3 · 1/3 + -7/4
Multiply 3 by 1/3:
1 + -7/4
Add -7/4 to 1:
-3/4
Final answer:

The expression 3x + y simplifies to -3/4 when x equals 1/3 and y equals -7/4.

Explanation:

To evaluate the expression 3x + y when x = 1/3 and y = -7/4, we simply substitute these values into the expression.

So 3x + y becomes 3*(1/3) - 7/4, which simplifies to 1 - 7/4.

To simplify this further, we convert 1 (which is the same as 4/4) and -7/4 to have the same denominator (which is 4). So, 4/4 - 7/4 equals -3/4.

So, the simplest form of 3x + y when x = 1/3 and y = -7/4 is -3/4.

Convert: y>3/2x-7/2 from point slope to standard form?

Answers

The goal is to get the inequality into the form Ax+By > C or Ax+By < C

First multiply both sides of the inequality by 2 to clear out the fractions
y > (3/2)x - 7/2
2*y > 2*( (3/2)x - 7/2 )
2y > 2*( (3/2)x ) + 2*( -7/2 )
2y > 3x - 7

Now get the x and y terms to one side; move the 7 to its own side
2y > 3x - 7
2y+7 > 3x - 7+7 ... add 7 to both sides
2y+7 > 3x
2y+7-2y > 3x-2y ... subtract 2y from both sides
7 > 3x-2y
3x-2y < 7 ... flip the two sides and the inequality sign

We finally have the inequality into the form Ax+By < C where 
A = 3
B = -2
C = 7

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

The answer is 3x-2y < 7
