Answer: Her daughter received 480 books
Step-by-step explanation:
Total collection of books =1,200
Total collection of books divided into 10 equal parts =1,200/10 = 120
Number of books given to her husband= 3 portions which means
120 x 3 =360books
Number of books given to her daughter=4 portions which means
120 x 4 =480books
The remaining which equals 3 portions were given to her three nieces.
An extended family is trying to plan a reunion and needs to find out where everyone would like to attend. Jill decides to send an e-mail to one person from each of the different families to get their opinion. She then follows up with those that she doesn't hear from. Is this a good way to collect data?
Answer:
I don't think so. Because what if that specific family member never checks their email. I think a good way would have been to email more than one or every person in that family (now since its extended you might not know everyone so just as many as you know of)

Answer:
C
Step-by-step explanation:
You have 2 totals so the number of males + females = 127 so x + y = 127
Then there are 23 more males than females, it did not say 23 times more so B is out, so the female number + 23 = male number so y + 23 = x
Therefore letter C is the answer.
Dalton built a linear model to show the height of a meteor falling to the Earth. The meteor starts at 100 km above the Earth's surface and falls at a rate of 20km per second. The x values represent the time in seconds and the y values represent the height of the meteor. What does the domain represent in context of the model?
Answer:
The domain represents the time of motion of the meteor as it falls from 100 km height above the Earth's surface at a speed of 20 km
Step-by-step explanation:
The given parameters from the question are;
The elevation of the meteor above the Earth's surface = 100 km
The rate at which the meteor falls = 20 km per second
The 'x' values represent the time in seconds and the 'y' values represent the meteor's height
Therefore, we have;
y = 100 - 20·x
The domain of a function is the set of inputs to the function
Therefore, the domain represent the time it takes the meteor to reach the given 100 km height above the Earth's surface
At the start x = 0 seconds
On the Earth's surface, y = 0, therefore;
0 = 100 - 20·x
x = 100/20 = 5
When the meteor just touches the Earth's surface x = 5 seconds
Therefore, the domain is 0 ≤ x ≤ 5.

The measure of the angle θ from the given triangle is 17.9°.
What are trigonometric ratios?The sides and angles of a right-angled triangle are dealt with in Trigonometry. The ratios of acute angles are called trigonometric ratios of angles. The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).
From the given triangle, AC=13 and BC=4 units.
We know that, sinθ=Opposite/Hypotenuse
sinθ= 4/13
sinθ= 0.3076
θ=17.9°
Therefore, the measure of the angle θ from the given triangle is 17.9°.

b+g=708
15b+10g=8640
Answer:
b=312
g=396
you can use substitution or elimination
Step-by-step explanation:
(b+g=708)10
(15b+10g=8640)1
(10b+10g=7080)-
(15b+10g=8640)
10b-15b=-1560
-5b=-1560
divide both sides by -5
b=312
then substitute
b+g=708
312+g=708
g=708-312
g=396
so b=312
g=396

Translate the following sentence into an equation using n for the unknown number. Then solve for n.
when 15 is decreased by three times a number, the result is 21
a.
15 - 372 = 21
n = -2
b.
312 - 15 = 21
n = -2
C.
31 - 15 = 21
n = 12
d.
15 - 3n2 = 21
n-2
Given:
15 is decreased by three times a number, the result is 21.
To find:
The equation for the given statement and solve it.
Solution:
Let n be the unknown number. Then,
Three times of a number = [tex]3n[/tex]
15 is decreased by three times a number = [tex]15-3n[/tex]
It is given given that the result after subtraction is 21. So,
[tex]15-3n=21[/tex]
[tex]-3n=21-15[/tex]
[tex]-3n=6[/tex]
Divide both sides by -3.
[tex]n=\dfrac{6}{-3}[/tex]
[tex]n=-2[/tex]
Therefore, the required equation is [tex]15-3n=21[/tex] and its solution is [tex]n=-2[/tex]. Hence, the correct option is (a).

Step-by-step explanation:
A model rocket is launched straight upward. The solid fuel propellant pushes the rocket off the ground at an initial velocity of 50 feet per second.
s(t)= -4t2 + 50t - 84. Show work to get credit
a. What is the maximum height reached by the rocket?
b. What time will it reach the maximum height?
c. You forgot to put the parachute in the rocket. When will the rocket hit the ground?
Answer:
a) 72.25sec
b) 6.25secs
c) after 10.5secs and 2 secs
Step-by-step explanation:
Given the height reached by the rocket expressed as;
s(t)= -4t^2 + 50t - 84
At maximum height, the velocity of the rocket is zero i.e ds/dt = 0
ds/dt = -8t + 50
0 = -8t + 50
8t = 50
t = 50/8
t = 6.25secs
Hence it will reach the maximum height after 6.25secs
To get the maximum height, you will substitute t - 6.25s into the given expression
s(t)= -4t^2 + 50t - 84
s(6.25) = -4(6.25)^2 + 50(6.25) - 84
s(6.25) = -156.25 + 312.5 - 84
s(6.25) = 72.25feet
Hence the maximum height reached by the rocket is 72.25feet
The rocket will reach the ground when s(t) = 0
Substitute into the expression
s(t)= -4t^2 + 50t - 84
0 = -4t^2 + 50t - 84
4t^2 - 50t + 84 = 0
2t^2 - 25t + 42 = 0
2t^2 - 4t - 21t + 42 = 0
2t(t-2)-21(t-2) = 0
(2t - 21) (t - 2) = 0
2t - 21 = 0 and t - 2 = 0
2t = 21 and t = 2
t = 10.5 and 2
Hence the time the rocket will reach the ground are after 10.5secs and 2 secs
