Answer:
B
Step-by-step explanation:
A right triangle is formed by the ground, the side of the house and the ladder.
The hypotenuse is the ladder
let the side of the house be h
Using the sine ratio in the right triangle formed, then
sin77° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{22}[/tex] ( multiply both sides by 22 )
22 × sin77° = h , then
h ≈ 21.44 ( to the nearest hundredth )
The ladder reaches 21.44 ft up the side of the house

you have a bag of 10 marbles. three of them are red ,five are blue, and two are green.what is the probability of not picking a green marble out of the randomly
Answer:
Not probabillity of picking a green marble is 80%
Step-by-step explanation:
Answer:
.80 or 4/5
Step-by-step explanation:
Probability is all about figuring out what you are or not going to get.
One good trick of figuring this out is taking what you don't want, (here its green marbles) take them out, then add all the marbles (G,B,R) and divide. Here you are dividing 8 by 10 which comes out to .80
The only other thing to do is simplify if needed. .80 turns into 8/10 and the only thing that 8 and 10 are divisible by is 2 so it would turn into 4/5
Hope this info can help ;)
one class of 28 students has a ratio of 3 girls to 4 boys. if this ratio holds true for the entire 6th grade of 140 students, how many girls are there
Answer: 105 girls because the ratio from girls to boys is 3:4 and that means that 3/4 are girls so 3/4 times 140 is 105

Milton took an elevator to the top of the Empire State Building in New York City and decided to walk down the steps to the bottom level. The building is 103 levels tall, and it takes Milton exactly 5 seconds to make his way from one level to the next. The equation below shows the level (l) that Milton is on after s seconds. `l\ =\ -\frac{1}{5}s\ +\ 103`

Winona leaves her home at 4:15 and arrives at the theatre one fourth hour later. What time does she arrive at the theatre?
Answer:
4:30
Step-by-step explanation: if she arrives one fourth hour later its......
When Winona leaves her home at 4:15 and arrives at the theatre after one-fourth hour i.e. 15 minutes so the time when she arrived is 4:30.
Calculation of the time;Since at the time when Winona leaves her home at 4:15 and arrives at the theatre after 15 minutes
So, she arrived at the time
= 4: 15 + 15 minutes
= 4:30
Hence, When Winona leaves her home at 4:15 and arrives at the theatre after one-fourth hour i.e. 15 minutes so the time when she arrived is 4:30.

A rectangle is 6 feet long and 4 feet wide. If each dimension is increased by the same number of feet, a new rectangle is formed whose area is 39 square feet more than the area of the original rectangle. By how many feet was each dimension increased?
Answer:
Each dimension increased by 3 ft.
Step-by-step explanation:
Area of the original rectangle = 4 * 6 = 24 square feet
Increased dimension = x ft
New length = 6 + x
New width = 4 +x
New area = (6 + x)(4 +x) {Use FOIL method}
= 6*4 + 6*x + x*4 + x*x
= 24 + 6x + 4x + x²
= x² + 10x + 24
New area = 24 + 39
x² + 10x + 24 = 63
x² +10x + 24 - 63 = 0
x² + 10x - 39 = 0
x² + 13x - 3x - 3*13 = 0
x (x + 13) - 3(x + 13) = 0
(x + 13)(x -3) = 0 {Ignore x + 13, as it gives negative value}
x - 3 = 0
x = 3

Answer:
X= - 2
Step-by-step explanation:
-3 (5x+6) - 3x = 6-6x
Remove the parentheses
-15x-18-3x=6-6x
Collect the like terms
-18x-18=6-6x
Move the variable to the left-hand side and change its sign
18x+6x=6+18
Collect the like terms
-12x=24
Divide both sides
X=-2

Find the gradient of the line segment between the points (-2,3) and (-4,-2).
Give your answer in its simplest form.
Given:
The two points are (-2,3) and (-4,-2).
To find:
The gradient of the line segment between the given points.
Solution:
The gradient is also known as slope.
The slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The endpoints of the line segment are (-2,3) and (-4,-2). So, the gradient of the line is
[tex]m=\dfrac{-2-3}{-4-(-2)}[/tex]
[tex]m=\dfrac{-5}{-4+2}[/tex]
[tex]m=\dfrac{-5}{-2}[/tex]
[tex]m=\dfrac{5}{2}[/tex]
Therefore, the gradient of the given line segment is [tex]m=\dfrac{5}{2}[/tex].
Alejandro bought 6 notebooks and 2 binders for $23.52. Cassie bought 3 notebooks and 4 binders for $25.53. What was the cost, in dollars, of 1 notebook?
Answer:
1 notebook $2.39
Step-by-step explanation:
n=notebook b= binder
6n +2b =23.52
3n +4b = 25.53
MULTIPLY THE FIRST BY -2 AND ADD BOTH
-12n -4b = -47.04
3n + 4b = 25.53
(b is eliminated since 4b -4b=0)
-9n = -21.51
9n = 21.51
n = 2.39

There is 5 yellow 3 red 4 green 2 blue and 2 white what is the probability of picking white then green
Answer:
2 (I think)
Step-by-step explanation:
4-2=2
Answer:
1/30
Step-by-step explanation:
the probability of picking white is 2/16 simplified to 1/8
the probability of picking a green would equal to 4/15
notice that it is not 4/16, because you already picked out one of the colours, and you are not replacing it, so if you take it out, then there is 15 left to pick from.
you would then multiply
1/8 x 4/15
= 4/120
simplified to
1/30
Simplify
-36 + x < 8
Step-by-step explanation:
add 36 to both sides to cancell out -36
-36+36=0
8+36=44
x<44
so all values for x are less than 44
