Answer:
500 students
Step-by-step explanation:
In Jonesville Louisiana 125 students attend last Friday high school football game. This about 25% of the students currently enrolled at the school. How many students are enrolled at the high school?
Let the number of students enrolled at the high school be represented as x
Hence:
25% of x = 125
25/100 × x = 125
25x /100 = 125
Cross Multiply
25x = 125 × 100
x = 125× 100/25
x = 500 students
When Vlad moved to his new home a few years ago, there was a young oak tree in his backyard. He measured it once a year and found that it grew by 26 centimeters each year. 4.5, years after he moved into the house, the tree was 29 centimeters tall.
How tall was the tree when Vlad moved into the house?
centimeters
How many years passed from the time Vlad moved in until the tree was 357 centimeters tall?
Answer:
Step-by-step explanation:
I dont really know but somekne wil lask in the comments so you can find the answer.
find the slope of the line
Answer:
Undefined
Step-by-step explanation:
The graph shows a vertical line. All vertical lines have a undefined slope.
This is because that while using the slope formula you will end of with the denominator being 0. You cannot divide by zero.
Hope this helps!

A right-angled triangle has sides of lengths (x+5)cm, (x-3)cm and 9cm. Calculate the value of x. Give your answer to 3 significant figures. (Quadratic Formula)
Answer:
x = (3.95 and -5.95)
Step-by-step explanation:
Given:
Hypotenuse = 9 cm
Perpendicular = (x+5) cm
Base = (x-3) cm
Find:
Value of x
Computation:
Using Pythagoras theorem
Hypotenuse² = Perpendicular² + Base²
9² = (x+5)² + (x-3)²
81 = x² + 25 + 10x + x² + 9 - 6x
2x² + 4x - 47 = 0
Quadratic Formula
x = [-b±√b²-4ac] / 2a
x = [-4±√16+376] / 2(2)
x = (3.95 and -5.95)

Answer:
h=(3v)/(pi r^2)
Step-by-step explanation:
you simply have to move everything to one side.
Answer:
h = [tex]\frac{3V}{\pi r^2}[/tex]
Step-by-step explanation:
Given
V = [tex]\frac{1}{3}[/tex]πr²h ( multiply both sides by 3 to clear the fraction )
3V = πr²h ( isolate h by dividing both sides by πr² )
[tex]\frac{3V}{\pi r^2}[/tex] = h

p + 4 < -24
p<-20
p < 28
p<-28
p < 20
Answer:
p < -28
Step-by-step explanation:
This is a simple solve - all we have to do is treat it like a normal equation and solve for p. This involves only one step - subtract 4 from both sides. We now end up with p < -28. And there you are!
Answer:
C
Step-by-step explanation:
P+4< - 24
P< - 24 - 4........collection of like terms
P< - 28

What is the value of x for the equation 4x – 2y = 6 if y= -3?
Answer:
x = 0
Step-by-step explanation:
Let's divid both sides of the equation by 2 first, so we don't have as much work to do in the next step:
[tex]4x-2y=6\\2x-y=3[/tex]
Substituting -3 for y:
[tex]2x-(-3)=3\\2x+3=3\\2x=0\\x=0[/tex]
Lin runs 2 3/4 miles in 2/5 of an hour. Tlyer runs 8 2/3 miles in 4/3 of an hour. How long does it take for each of them to run 10 miles
Answer:
Lin 1.454 h
Noah 1.54h
Step-by-step explanation:
From the above, we were given that;
Lin ran 2 3/4 miles in 2/5 an hour. Then, Noah ran 8 2/3 miles in 4/3 an hour
Speed of Lin
V = [(2 3/4)/(2/5)] mph
V = [(11/4)/(2/5)] mph
V = 6.875mph
Speed of Noah
V = [(8 2/3)/(4/3)] mph
V = [26/3)/(4/3))] mph
V = 6.5mph
The time taken by Lin to cover 10 miles
t = 10/6.875
t = 1.454h
The time taken by Noah to cover 10 miles
t = 10/6.5
t = 1.54h
In the following figure, find the value of x
Answer:
18
Step-by-step explanation:
All the angles added up will equal 180 degrees (recall a straight line has an angle of 180 degrees).
Therefore, you can create the following equation and solve for x:
[tex]2x+3x+2x+3x=180\\10x=180\\x=\frac{180}{10}\\x=18[/tex]
Answer:
x=18

Answer:
B. 16.9
Step-by-step explanation:
Reverse Pythagoreans theorem C^2 - B^2 = A^2 so
7^2 - 5^2 = c^2 and it comes out to
49-25 = 24 the square root of that is 4.9 (rounded)
But we are lookign for the perimeter so
4.9 + 7 + 5 = 16.9

Answer:
AB is 104
Step-by-step explanation:
In the given figure
∵ CE bisects the segment AB
→ That means CE intersects AB at the midpoint of AB
∵ CE ∩ AB at point F
∴ F is the midpoint of AB
→ The midpoint of a segment divides it into two equal parts
∵ The point F divides AB to FA and FB
∴ FA = FB
∵ FA = 7x + 10
∵ FB = 9x - 2
→ Equate them
∴ 9x - 2 = 7x + 10
→ Add 2 to both sides
∵ 9x - 2 + 2 = 7x + 10 + 2
∴ 9x = 7x + 12
→ Subtract 7x from both sides
∵ 9x - 7x = 7x - 7x + 12
∴ 2x = 12
→ Divide both sides by 2
∴ x = 6
→ Substitute the value of x in FA and FB
∵ FA = 7(6) + 10 = 42 + 10 = 52
∵ FB = 9(6) - 2 = 54 - 2 = 52
∵ AB = FA + FB
∴ AB = 52 + 52 = 104
∴ AB = 104

If you can't read my writing, this is the questions:
'Calculate the perimeter of this sector.
Give your answer in terms of pi.'
Answer:
Perimeter of the sector = (36 + 8π) cm.
Step-by-step explanation:
Formula to find the of an arc of the circle is,
Length of the arc = [tex]\frac{\theta}{360}(2\pi r)[/tex]
Here, θ = central angle formed by the arc
r = radius of the circle
Therefore, length of the arc given in the picture = [tex]\frac{80}{360}(2\pi) (18)[/tex]
= 8π cm
Perimeter of the sector = Sum of all sides of the sector
= Length of radius + length of the arc + length of radius
= 18 + 8π + 18
= (36 + 8π) cm
Perimeter of the sector is (36 + 8π) cm.
Let x denote the number of broken pencils in a randomly selected 50-count box from a local office supply store. The variable x has the
following probability distribution:
a)
0.82; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.82 from the
mean
b)
0.31; if we were to select many boxes of pencils randomly, we would expect about 0.31, on average, to contain broken pencils
c)
0.65; if we were to select many boxes of pencils randomly, the number of broken pencils would typically vary about 0.65 from the
mean
d)
0.52; if we were to select many boxes of pencils randomly, we would expect about 0.52 to have no broken pencils
e)0.13; if we were to select many boxes of pencils randomly, we would expect about 0.13, on average, to contain broken pencils
Answer:
0.82

Answer:
x = 4
Step-by-step explanation:
Since the rectangles are similar, use a ratio.
15/6 = 10/x
or
6/15 = x/10
I will use 15/6 = 10/x to solve this problem, but both ratios should work to solve this problem.
15/6 = 10/x
Cross Multiply:
6(10) = 15x
Solve:
60 = 15x
x = 4

m25 =
Answer/Step-by-step explanation:
✔️m<1 + 52° = 180° (consecutive angles angle)
m<1 = 180 - 52
m<1 = 128°
✔️m<2 = 52° (alternate interior angles are congruent)
✔️m<3 = 47° (alternate interior angles are always equal)
✔️m<4 + 47° = 180° (consecutive angles)
m<7 = 180 - 47
m<7 = 133°
✔️m<5 = 180 - (52 + 47)
m<5 = 180 - 99
m<5 = 81°
