Answer:
$5.80
Step-by-step explanation:
To answer, we must first subtract the toal cost Joe paid by the amount he paid for his drink, because ha paid for his drink separately. so:
3.20 - 1.75 = 1.45
And because there were a total of 4 friends, we mulitply the answer by 4:
1.45 * 4 = 5.8
So, the bag of donuts costed $5.80

here is an example jy26903
Answer:
I meant an example for a problem like the one you posted.
Either way, I'll try to help.
in the example, you're finding out what percentage of 352 is 226.6.
So divide 226.6 (The number that you're using to find what percentage it is of 352) by 352( the number you're finding the percentage of.)
226.6/352= 0.64375, and multiply the quotient by 100 to get 64.375. You're rounding up by the nearest hundredth, so the 7 turns to 8. (5 or more means rounding up.)
your final answer for the example is 64.38%. So Try that with your next problem.
For the one you're working on, divide 110.9 by 100 and then multiply it by 419.
You'll get 464.671.

(a) Find an angle between 0° and 360° that is coterminal with 1020
Answer:
300°
Step-by-step explanation:
Subtract 360° from 1020° and repeat until angle is in required range
1020° - 360° = 660°, then
660° - 360° = 300°
300° is coterminal with 1020°
An angle between 0° and 360° that is coterminal with 1020° is 300°.
What are Coterminal angles?Coterminal angles are defined as the angles which has the same terminal side with the initial side on the positive side of X axis.
We have to find an angle between ° and 360° that is coterminal with 1020°.
Subtract 360° from the given angle until the angle obtained is between 0° and 360°.
1020 - 360 = 660
660 - 360 = 300
So 300° is a coterminal angle with 1020.
Hence the coterminal angle is 300°.

What is the solution to the system of equations
Answer:
(2, - 5 )
Step-by-step explanation:
Given the 2 equations
y = - 3x + 1 → (1)
4x + y = 3 → (2)
Substitute y = - 3x + 1 into (2)
4x - 3x + 1 = 3
x + 1 = 3 ( subtract 1 from both sides )
x = 2
Substitute x = 2 into (1) for corresponding value of y
y = - 3(2) + 1 = - 6 + 1 = - 5
solution is (2, - 5 )

Express each rate as a unit rate.
a. 32 teams in 4 divisions
b. $2.70 for 15 ounce
Answer:
To solve for the unit rate, know that the final answer must be out of 1. Or it is the quantity or amount of something per unit of measurement.
For instance in the above question, the unit rate for 32 teams in 4 divisions would be 8 teams per division.
Likewise for the other question it would be 270/15.

B.)x=1 and y=2 or (2,1)
C.)x=10 and y=20 or (10,20)
D.)x=2 and y=4 or (2,4)
Answer:
D) x = 2 and y = 4 or (2, 4)
Step-by-step explanation:
Given system of equations:
[tex]\begin{cases}3x+y=10\\-4x+2y=0\end{cases}[/tex]
Multiply Equation 1 by -2:
[tex]\implies -6x-2y=-20[/tex]
Add this to Equation 2 and solve for x:
[tex]\implies (-4x+(-6x))+(2y-2y)=(0+(-20))[/tex]
[tex]\implies -10x=-20[/tex]
[tex]\implies x=2[/tex]
Substitute the found value of x into Equation 1 and solve for y:
[tex]\implies 3(2)+y=10[/tex]
[tex]\implies 6+y=10[/tex]
[tex]\implies y=10-6[/tex]
[tex]\implies y=4[/tex]
Therefore, the pair on numbers (x, y) that satisfies both equations is (2, 4)

What expressions are equivalent to y4 - 625?
Answer:
option D
Step-by-step explanation:
a² - b² = (a + b) (a - b)
625 = 5 * 5 * 5 * 5 = 5⁴
y⁴ - 625 = y⁴ - 5⁴
= (y²)² - (5²)² {a = y² ; b = 5²}
= (y² + 5²)(y² - 5²)
= (y² + 25)(y² - 5²)
= (y² + 25)(y + 5)(y - 5)

A plant is 3 inches tall when you purchase it and grows 2 inches per month. Write an equation in slope intercept form that represents the height y(in inches) of the plant after x months.
Answer:
y = 3 + 2x
Step-by-step explanation:
In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.
y = 3 + 2x

How can you see that a reflection could work without knowing where the line of reflection is? If you get the answer right I'll paypal, venmo or cash app you $50. So drop your paypal, venmo or cash app along with your answer.
Note how going from R to S to T to U has us going counterclockwise. In contrast, going from R' to S' to T' to U' has us going the opposite direction going clockwise. This change in orientation strongly implies that a reflection has been done. Reflections always flip orientation.
-----------------------------------------
Here's how we can find the line of reflection.
Draw a line segment from point R to point R'. Mark the midpoint of the segment as point A
Repeat this process to form a segment from S to S'. Mark the midpoint as point B.
The line of reflection will pass through points A and B. This is because the line of reflection is equally distant between the original point (such as point R) and its reflected point (such as R'). This must mean that the line of reflection goes through the midpoint of segment UU' and also segment TT'.
Refer to the diagram below.

Last year the depth of the river was 4.2 feet deep. This year it dropped 25%. Find the depth of the river this year to cross it.
Answer:
The river is 3.15 feet deep.
Step-by-step explanation:
First let's recognize what we need to find: the depth of the river
We know last year the river was 4.2 feet deep, but it dropped 25%. This means we also need to find how much it dropped. To find this, we need to know what 25% of 4.2 is. Write an equation for this.
y = 25% of 4.2
y = 0.25 • 4.2
y = 1.05
This means that the river dropped 1.05 feet. To know its depth now, we need to subtract 1.05 from 4.2. Write an equation for this.
d = 4.2 - 1.05
d = 3.15
The river is 3.15 feet deep.
Hope this helps!

Jane sold a house for $160,000 that she listed. Her broker charges a % commission and she receives 60% of the commission. How much did Jane receive?
Jane gets 5,760.
What is commission?Commissions are a form of variable-pay remuneration for services rendered or products sold.
Given:
House sold for $160,000 with a listing commission of 6%
So, full commission
=160,000*0.06
= 9, 600
And, jane's share will be
