A class of sixty students voted for class president. 30% voted for Brad and 70% voted for Jane. How many votes did the winner get
The winner got a total of 42 votes.
What is Percentage?
This can be defined as a number or ratio expressed as a fraction of 100. It is usually calculated by parts/whole × 100.
In this scenario, Jane was the winner as she got a higher percentage of votes. To calculate the exact number of vote we have to do the following:
70%/100% × 60 = 42 votes.
Therefore, the total number votes the winner got is 42.

6y + 4 – 3y = -5 + y + 17
Answer:
Step-by-step explanation:
6y+4-3y=-5+y+17
6y-3y-y= -5+17-4
2y=8
y=4
Answer:
y = 4
Step-by-step explanation:
6y + 4 - 3y = -5 + y + 17
First, we have to combine like terms on each side of the equation:
3y + 4 = y + 12
Then, we have to combine the terms from both sides of the equation:
3y + 4 = y + 12
-4 -4
3y = y + 8
-y -y
2y = 8
Then, we divide so we only have y on the left side:
2y = 8
/2 /2
y = 4

Suppose a city with population 500,000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 21 years?
Answer:
2,070,281
Step-by-step explanation:
let x = number of years
let y = population
Given:
initial population = 500000rate of increase = 7%y = 500000 × 1.07^x
when x = 21:
y = 500000 × 1.07^(21) = 2070281.187... = 2,070,281

a) On January 1st Mary weighed 92 pounds. Over the next 6 months, she gained (g) pounds, then lost (x) pounds. Her new weight can be represented by the equation w = 92+ g -1. If g = 15 and x =8 , what is mary's new weight?
Answer:
w = 99 pounds
Step-by-step explanation:
The problem states that Mary's weight is given by the equation:
w = 92 + g - 1
I believe the "-1" should be "-x." -1 would mean that Mary lost 1 pound. But we know that Mary lost 8 pounds, which is designated as x.
The correct equation is:
w = 92 + g - x
============
Using the correct equation, and g=15 and x=8, Mary's new weight is:
w = 92 + 15 - 8
w = 99 pounds
im givin away myy last of points here is my question anyone can answer dis even people who just want points: Charise is buying 6 packets of seeds to plant in her garden. Each packet of seeds is $2.19. Estimate her total cost by rounding. Is the estimate an underestimate or an overestimate?
$12; underestimate
$18; underestimate
$12; overestimate
$18; overestimate
Answer:
It would be $12 overestimate
Step-by-step explanation:
$2.19 rounded to one significant figure would be $2.00
$2.00 multiplied by 6 would be $12
However since 19 cents is over $2, this means it's a definite overestimate

A farmer is placing fencing material around her triangular garden. The vertices of her garden are located at the points (−1, 5), (4, 2), and (9, −4) on a coordinate grid. If each unit on the grid represents a foot and the material costs $8 per foot, how much will she pay for the material on the side between points (−1, 5) and (4, 2)?
Answer:
[tex]Cost= \$47[/tex]
Step-by-step explanation:
Given
Vertices: (−1, 5), (4, 2), and (9, −4)
Cost per foot = $8
Required
Determine the cost of fencing (-1, 5) and (4, 2)
First, we need to determine the distance between (-1, 5) and (4, 2)
Distance, d is calculated as follows:
[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]
Where
[tex](x_1,y_1) = (-1, 5)[/tex]
[tex](x_2,y_2) =(4, 2)[/tex]
So, we have:
[tex]d = \sqrt{(4 - (-1))^2 + (2 - 5)^2}[/tex]
[tex]d = \sqrt{(4 +1))^2 + -3^2}[/tex]
[tex]d = \sqrt{5^2 + -3^2}[/tex]
[tex]d = \sqrt{25 + 9}[/tex]
[tex]d = \sqrt{34}[/tex]
[tex]d = 5.83095189485[/tex]
[tex]d = 5.831[/tex] -- Approximated;
If the cost of 1 foot is $8.
5.831 feet will cost:
[tex]Cost= 5.831 * \$8[/tex]
[tex]Cost= \$46.648[/tex]
[tex]Cost= \$47[/tex] -- Approximated
PLEASE HELP! WILL MARK BRAINLIEST - What is 2(n+1)?
Answer:
2n + 2
Step-by-step explanation:
To get the answer you must do distributive. This means you have to multiply 2 and N and 2 and 1. Next, after you multiply these answers you put them together with whatever operation sign is there. In this case, the operation sign here is an addition. Therefore the answer would be 2n + 2.

The first error Jayden made in teh proof is: D. the sine ratio, sin(X) = h/x is incorrect, its should be sin(Z) = h/x.
What is the Sine Ratio?Whn solving a right triangle, the sine ratio can be used which is expressed as, sin ∅ = opposite side/hypotenuse, given that ∅ is the refrence angle.
In the proof of Jayden, the area of the triangle is correct, which is 1/2(base × height).
However, the sine ratio is wrong.
Therefore, the first error Jayden made in teh proof is: D. the sine ratio, sin(X) = h/x is incorrect, its should be sin(Z) = h/x.

Louie drove 50 1/8 miles and used 2.5 gallons of gas. Find the number of miles driven per gallon of gas.
Hey there!
=> 50 1/8 {improper fraction}
=> 401/8 {proper fraction}
=> 401/8 ÷ 2.5
=> 50.125 ÷ 2.5 { Divide}
=> 20.05
Convert [tex]20.05[/tex] to fraction
Rewrite the decimal number as a fraction with 1 in the denominator
20.05=20.05/1
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 102 = 100
20.05/1×100/=2005/100
Find the Greatest Common Factor (GCF) of 2005 and 100, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,
