Answer:
89/160
Step-by-step explanation:
Total number of students= 320
Total number of students=x+y=320
Let x= number of boys
Let y= number of girls
If there are 36 more boys than girls:
36+y=x
x+y=320 ( given x= 36+y)
36+y+y=320
36+2y=320
2y=320-36
2y=284
y=284/2
y=142
Therefore number of girls=142
Since 36+y=x
36+142=x
x=178
Therefore number of boys =178
Fraction of students that are boys=
178/320
89/160

Nolan rides his bike 63 miles in 270 minutes. What is his average speed in miles per hour?
miles per hour
Time = 270 mins = 4 hr. 30 mins = 4½ hr.
distance = 63 miles
thus, speed = distance travelled / time taken
speed = 63/(4½) miles per hr
speed = 14 miles per hr.

Write an algebraic expression to model the given context. Give your answer in simplest form. the price p of a coat reduced by a 5% discount
Answer:
We conclude that the expression of the price p of a coat reduced by a 5% discount will be: 0.95 p
Step-by-step explanation:
Let 'p' be the original price
Discount = 5% = 0.05
The discount amount can be calculated by multiplying the original price by 5% or 0.05
Discount Amount = 5% × p
= 0.05 × p
= 0.05 p
Given that the price p of a coat reduced by a 5% discount.
Thus, the price after 5% discount can be calculated by subtracting the discount amount i.e. 0.05 p from the original price p.
Thus,
The expression of the price p after 5% discount = p - 0.05 p
= 0.95 p
Therefore, we conclude that the expression of the price p of a coat reduced by a 5% discount will be: 0.95 p

Find the value of x and measure of <) W.
7x+12
9x-6
Answer:
x = 9; ∡W = 75°
Step-by-step explanation:
in a parallelogram, opposite angles are congruent
7x + 12 = 9x - 6
-2x = -18
x = 9
Find ∡W by substituting 9 for 'x': 7(9) + 12 = 63 + 12 = 75
Two triangles are similar.The the smaller triangle has side 10,20 and 15 units the larger triangles longest side is 52 units.What is the perimeter of the largest triangle?
Answer: The perimeter of the largest triangle = 117 units.
Step-by-step explanation:
Sides of smaller triangle = 10,20 and 15 units
Longest side = 20 units
Longest side of larger triangle = 52 units
Sides of two similar triangles are proportional.
Let k be proportionality constant.
[tex]k=\dfrac{\text{Length in larger triangle}}{\text{Length in smaller triangle}}[/tex]
[tex]k=\dfrac{52}{20}\\\\\Rightarrow\ k=\dfrac{13}{5}[/tex]
Length of other two sides,
[tex]10\times\dfrac{13}{5}, 15\times\dfrac{13}{5}\ i.e.\ 26\text{ units}, 39\text{ units.}[/tex]
So sides of larger triangle = 52 units, 26 units , 39 units
Perimeter of largest triangle = 52 +26+39 = 117 units
Hence, the perimeter of the largest triangle = 117 units.

know vey hard. but need help. humanity
Answer:
a. AB = 17 m
b. AC = 19.2
Step-by-step explanation:
✔️Length of AB:
Apply pythagorean theorem
AB² = (25 - 10)² + 8² = 15² + 8²
AB² = 289
AB = √289
AB = 17 m
✔️Length of AC:
Apply pythagorean theorem
AC² = AB² + BC²
AC² = 17² + 9²
AC² = 370
AC = √370
AC = 19.2 (to 1 d.p)

Hello! :)
[tex]\large\boxed{x = 4}[/tex]
In order for the figure to be a kite, each pair of opposite sides must be congruent. Therefore:
GL ≅ GT, and LO ≅ TO
We can solve for x by setting GL and GT equal to each other:
4x + 1 = 17
Subtract 1 from both sides:
4x = 16
Divide both sides by 4:
x = 4.
Verify that it satisfies LO ≅ TO:
6(4) - 3 = 21
24 - 3 = 21
21 = 21.
Therefore, x = 4.
Answer:
[tex]\huge\boxed{x=4}[/tex]
Step-by-step explanation:
Kites are quadrilaterals that have two pairs of two sides that are the exact same length. These sides will be adjacent to one another and therefore they will be the same value.
Looking at the question, we can see that the sides [tex]4x+1[/tex] and [tex]17[/tex] will be two pairs of equal length sides. Therefore, we can solve for x by setting the two equal to each other (as they both will be the same value)
[tex]4x+1= 17[/tex]
Now we can solve for x.
[tex]4x+1=17[/tex] [tex]4x=16[/tex] [tex]x=4[/tex]We can double check this by testing in the same way with the second pair of equal sides, [tex]6x-3[/tex] and [tex]21[/tex].
[tex]6x-3= 21[/tex] [tex]6x=24[/tex] [tex]x=4[/tex]Therefore, to make this figure a kite, x=4.
Hope this helped!

Cynthia was paid 20 cents pr board for painting the fence. If she was paid $10 for painting half the boards, how many boards were there?
Answer:
100 boards
Step-by-step explanation:
Step one:
Given data
We are told that Cynthia was paid 20 cents per board for painting the fence
that is for 1 board painted she gets $0.2
If she was paid $10
let us find the number of boards she painted for $10
= 10/0.2
=50 boards
This means that the total boards were 50*2= 100 boards

Which is a correct classification for the triangle?
O equiangular triangle
O right triangle
O acute triangle
O obtuse triangle
Answer:
right angle
Step-by-step explanation:
180-(31+59)= 90
The correct classification of the triangle should be considered as the right triangle.
What is the right triangle?A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangled triangle, is a triangle in which one angle is a right angle, i.e., in which two sides are perpendicular. The relation between the sides and other angles of the right triangle is the basis for trigonometry.
here, we have,
given that,
In the case when the sum the two given angles is 90,
so, the other angle will be 90
so, its a right triangle.
A right angled triangle is a triangle in which one of the angles is 90°. A 90-degree angle is called a right angle, and hence the triangle with a right angle is called a right triangle. Further, based on the other angle values, the right triangles are classified as isosceles right triangles and scalene right triangles.
Hence, The correct classification of the triangle should be considered as the right triangle.

What is the product of 3x+4 and 6x2-4x+2
Answer:
18x³ + 36x² + 22x + 8
Step-by-step explanation:
Multiply 3x + 4 times each term in the latter equation. 6x² times 3x + 4 is 18x³ + 24x².
3x + 4 times 4x is 12x² + 16x.
3x + 4 times 2 is 6x + 8.
Combine like terms to get 18x³ + 36x² + 22x + 8
It costs $3.75 to buy 3/4 of a pound of walnuts how many pounds of walnuts can you purchase with 11.25
Answer: 2.25 or 2 1/4 pound of walnut
Step-by-step explanation: So here you need to figure out how many pound of walnut can you purchase with 1 dollar first. To do that, you need to -- 3.75 ÷ 3/4 which you can convert to 3.75 ÷ 0.75 and the answer would be 5.
Now if you do this -- 11.25 ÷ 5 = 2.25
So the answer is 2.25 or 2 and 1/4 pound of walnut
