Please help! Also please don’t comment just for points it’s not funny and I need this so I can raise my score back up.
Answer:
x = 8 and x = -3.
Step-by-step explanation:
-x^2 + 5x + 24 = 0 at the x intercepts.
Divide thru by -1:
x^2 - 5x - 24 = 0
(x - 8)(x + 3) = 0
x - 8 = 0 , x + 3 = 0
x = 8 and x = -3.

round 34 1/8 to the nearst whole number
Answer:
34
Step-by-step explanation:
Because it is a mixed fraction, it tells us the whole number already. After that, we need to look at the actual fraction part and decide if it's large enough to round the whole number up. 1/8 is not, so we keep the whole number at 34
Answer:
That would be 34

Step-by-step explanation:
Solve the following equation for x.
3x - 9 = -42
Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11

what percent of 82 is 9.75. Round your answer to the nearest tenth
Hi there!
8 would be the nearest ten of 7.995..
1.Multiply 82 with 0.01:
[tex]82[/tex]·[tex]0.01=0.82[/tex]
2.Multiply the terms:
[tex]0.82[/tex]·[tex]9.75=7.995[/tex]
3.Round the term:
[tex]7.995=8[/tex]
Therefore, 82% of 9.75 in nearest tenth is 8.

100 points ! What is the area of the following composite figure? All angles are right angles.
24 m^ 2
27 m ^2
29 m^ 2
22 m^ 2
Answer:
24m²
Step-by-step explanation:
..,.................
Area = 5*4+2*1+2*1
Area = 20+2+2
Area = 24m²
Answer:
24 m^2
Step-by-step explanation:
We need to study the structure well
We can find the magnitude of the big rectangle. We will need to find the total length and total breadth of the big rectangle
Then we remove the area of the four squared cut out from the big rectangle.
Total length of the rectangle is 5+1+1=7m
Then the length of the breath of the rectangle is 2+1+1=4m
So area of rectangle is given as length × breadth
Area= l×b
Area=7×4=28m²
Area of the big rectangle is 28m²
Then the squared is made of dimension 1m by 1m
Area of a square is s²
Then, a=1m
Area of the square= 1²=1m²
There are four squared side
Then, the total area of the four squared is 4×1=4m²
Then the required area is
Area=Total area - area of four squared side
Area=28m²-4m²
Area =24m²
Area of the figure is 24m²
The correct option is A.
In ΔOPQ, q = 83 inches, p = 80 inches and ∠P=70°. Find all possible values of ∠Q, to the nearest degree
Answer:
77.12°
Step-by-step explanation:
Given that:
In triangle OPQ
∠P=70°
line q = 83 inches
line p = 80 inches
To find ∠Q; we use the since rule:
[tex]\dfrac{Sin \ Q}{q} = \dfrac{Sin \ P}{p}[/tex]
[tex]\dfrac{Sin \ Q}{83} = \dfrac{Sin \ 70}{80}[/tex]
[tex]Sin \ Q= \dfrac{Sin \ 70 \times 83}{80}[/tex]
[tex]\text{Sin \ Q= 0.9749}[/tex]
[tex]Q=Sin ^{-1}( 0.9749)[/tex]
[tex]\mathbf{Q = 77.12^0}[/tex]

Convert the following equation to slope-intercept form:
5x - 15y = 105
Answer:
D
Step-by-step explanation:
You need to solve the equation so that it looks like y = mb + b
So -15y = -5x + 105, then divide both sides by -15 so y = -5/-15 x + 105/-15
y = [tex]\frac{1}{3}[/tex] x - 7

Now, divide 3.50 by 1/4 (or 0.25) to get 14
14 1/4 centimeter cubes will fill the prism
You are in a hurry and I don't think that you really need the explanation so its 224 cubes
3.5(2.25 + x) = 14
x=
Answer:
x = 1.75
Step-by-step explanation:
Given

The number of people who sleep 8-8.9 hr per night is about how many times the number who sleep 6-6.9 hr a night
Answer:
3.75 times
Step-by-step explanation:
From the histogram plot of the data :
The number of people who sleep 8 - 8.9 hour per night is about 375
The number of people who sleep 6 - 6.9 hour per night is about 100
Therefore, to compare how many times the number of people who sleep 6 - 6.9 hrs and 8 - 8.9 hrs :
8 - 8.9hrs = 6 - 6.9 hrs * x
375 = 100x
x = 375 / 100
x = 3.75
Hence, the number of people who sleep 8 - 8. 9 is 3.75 times the number of people who sleep 6 - 6.9
