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.

The area of AXYZ is žyh
by the definition of the area of a triangle. Using the sine ratio, sin(x) = . Also, asin(x) = h is true by the
multiplication property of equality. So, by the substitution property of equality, the area of AXYZ is 2xysin(x).
Where did Jayden make his first error in the proof?
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.

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.

which of the following equation is true?
How are the areas of the smaller squares related to the area of the biggest square? Do you notice something?
If a = the side of one small square and b = the side of the other small square and c = the side of the biggest square, then how could you write an equation using a, b, and c with exponents?
This is the Pythagorean Theorem for all Right Triangles. ____________________
Answer:
The sum of area of two smaller squares is equal to the area of bigger square
An equation using a, b, and c with exponents is [tex]c^2=a^2+b^2[/tex]
Step-by-step explanation:
Let a be the side of the smallest square , b be the side of other smaller square and c be the side of biggest square
Area of square with side a = [tex]Side^2 = a^2[/tex]
Area of square with side b = [tex]Side^2 = b^2[/tex]
Area of square with side c =[tex]Side^2 = c^2[/tex]
Refer the attached figure
In triangle ABC
[tex]\angle A = 90^{\circ}[/tex]
So, We can use Pythagoras theorem over here
AB = a = Base
AC = b = Perpendicular
BC = c = Hypotenuse
[tex]Hypotenuse^2=Perpendicular^2+Base^2\\c^2=a^2+b^2[/tex]
So, The sum of area of two smaller squares is equal to the area of bigger square
An equation using a, b, and c with exponents is [tex]c^2=a^2+b^2[/tex]
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

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,
2005÷5/100÷5=40/120
Simplify the improper fraction,
=20 1/20
Or, 401/20

1. Second option. Value of the first column is less than the second column's value
2. Right by 4 units
3. (-1, -6)
4. Function 1 and 2 have the same maximum

1. look at the photo
2. look at the photo
3. look at the photo
4. I used the formula -b/2a to find the x-value of the vertex. I got 0 (there is no b) and then I subbed it into the function and y = 9. Hence the vertex of the first function is (0,9) which is the same as the second function
5. The vertex of the f(x) is (-3, -3) and the vertex of g(x) is (3, 12). To find the difference you would do 12 - (-3), which would become 12 + 3 = 15
