Answer:
There are 40 books total
Step-by-step explanation:
you need to set a proportion
The first fraction is 55/100 it's over 100 because it's percent
the other fraction is 22/x the 22 is out of a total number so that's why it's on top and x because you don't know the total number of books
then you multiply diagonally
55×x= 22×100
55x=2,200
Then you solve it like a regular equation by dividing both sides by 55
x=40
Answer:
There are a total of 40 books in the box.
work out the percentage change to 2 decimal places when a price of 200 is increased to 210.99
Answer:
105.5%
Step-by-step explanation:
The percentage change can be calculated as follows
= 210.99/200
= 1.05495 × 100
= 105.5%
Hence the percentage change is 105.5%

Answer:
Area of sector ≈ 15.6π (nearest tenth)
Step-by-step explanation:
Given:
radius = 5 cm
Central angle in radians = ∅ = 5π/4
Required:
Area of the sector
Solution:
Area of sector = ½*r²*∅
Plug in the values into the formula
Area of sector = ½*5²*5π/4
= ½*25*5π/4
= 12.5*5π/4
= (12.5*5π)/4
Area of sector = 15.625π ≈ 15.6π (nearest tenth)

What is the value of X
Answer:
11=x
Step-by-step explanation:
since the lines are parallel the distances between each section of line is proportional to each other.
5/6=(x-1)/12
multiply both sides by 12
12(5/6)=(x-1)12/12
10=(x-1)
add 1 to both sides
10+1=x-1+1
11=x

Solve the following system of equations algebraically using the ELIMINATION METHOD. Show all work.
x-3y=1
3x-5y=11
Answer:
(7,2)
Step-by-step explanation:
Multiply the first equation by -3
(x-3y=1) = -3x+9y=-3
Combine like terms with the new equation and the second equation
(-3x+9y=-3) + (3x-5y=11) = 4y=8
Divide each side by 4
4y/4=8/4
y=2
Plug in 2 for y in any equation. It doesn’t matter which one
x-3(2)=1
Distribute
x-6=1
Add 6 to both sides
x-6=1
+6 +6
x=7
Answer: x = 7 y = 2
(7, 2)
Step-by-step explanation:
Multiply the first equation by -3 and the second by 1:
-3(x - 3y = 1)
1(3x - 5y = 11)
Becomes:
-3x + 9y = -3
3x - 5y = 11
Add the equations to eliminate x:
-3x + 9y = -3
3x - 5y = 11
4y = 8
Solve for y by dividing by 4:
4y/4 = 8/4
y = 2
Now we plug in y to the first equation:
x - 3 ( 2 ) = 1
x - 6 = 1
Add 6 to both sides:
x - 6 + 6 = 1 + 6
x = 7

Trapezoid: b1 =3m; b2 = 4m
A= 7m 2 What the next missing dimension?
9514 1404 393
Answer:
h = 2m
Step-by-step explanation:
We can put the given values into the area formula and solve for the missing one.
A = (1/2)(b1 +b2)h
7m²= (1/2)(3m +4m)h
7m² = (7/2)m·h
(7m²)(2/(7m)) = h = 2m
The missing height is 2 m.

Answer:
1) 27.374
2)9.177
Step-by-step explanation:
1) To get the value of x , we use the appropriate trigonometric ratio
From what we are given;
we have the hypotenuse ( the side facing the right angle) and the adjacent
The trigonometric identity to use here is the cos
The cos of an angle is the ratio of the adjacent to the hypotenuse
cos 64 = 12/x
x = 12/cos 64
x = 27.374
2) Here, we are given the hypotenuse and the opposite
The trigonometric ratio to use here is the sine
the sine of an angle is the ratio of the opposite to the hypotenuse
thus, we have it that;
sin 35 = x/16
x = 16 sin 35
x = 9.177
What is the slope of the line that passes through the points (-2,2) and (7,3)
Answer:
Step-by-step explanation:
Given points
let ( x1, y1 ) = ( - 2 , 2) and (x2 , y2 ) = (7, 3)
slope of the line (m)
= ( y2 - y1) / (x2 - x1)
= ( 3 -2 ) / ( 7 + 2)
= 1 / 9

find the area plz and thank u
Answer:
A = 173.82
Step-by-step explanation:
[tex]A = 2 (1 + \sqrt{2}) a^{2}[/tex]
a = 6
substitute 6 for a
A = 2 (1 + [tex]\sqrt{2}[/tex]) [tex]6^{2}[/tex]
solve:
A = 2 (1 + [tex]\sqrt{2}[/tex]) 36
A = 173.82
Answer:
Around 173.8 km (rounded to the nearest tenth of a km
Step-by-step explanation:
The area of an octagon can be found using the expression:
A=2(1+sqrt of 2)a^2
plug your side of 6 in to create the following equation:
A=2(1+sqrt of 2)(6^2)
Solve for A:
A= (2 + 2*sqrt of 2)(36) I multiplied 6 by 6 to get 36 and used distributive property on the other section.
A=72+72sqrt of 2
plug that in a calculator and you get around 173.8 km
Evaluate the following equation for x. 2/5x = −20
What number is exponent?
Answer:
2
Step-by-step explanation:
The base B represents the number you multiply and the exponent "x" tells you how many times you multiply the base, and you write it as "B^ x." For example, 8^3 is 8X8X8=512 where "8" is the base, "3" is the exponent and the whole expression is the power.
