Sand costs three times as much as rocks per pound. If sand is $9.60 per pound, how much are rocks per pound?
Answer:
Rock costs $3.20 per pound.
Step-by-step explanation:
Because sand costs three times as much as rocks per pound, you can determine the cost of rocks per pound by dividing the cost of sand per pound by three:
[tex]\frac{9.60}{3}[/tex] [tex]= 3.20[/tex]
solve (2x+3) ( x-7)=0
Answer:
Step-by-step explanation:
Either,
2x+3=0
2x=-3
x=-3/2
Or,
( x-7)=0
x=7

Andre types 208 words in 4 minutes. Noah typed 342 words in 6 minutes
A) Who typed faster
B) How many words can andre type in 10 minutes
C)Would you find the unit rate of words per minute or the unit rate of minutes per word to
figure out how long it would take Noah to write 1710 words? Why? (You do not need to
solve, just choose and explain why).
Answer:
Noah types faster because he can type more words per minute.
Step-by-step explanation:
For Andre you would divide 208 words by 4 minutes getting 52 words per minute. Then, for Noah divide 342 words by 6 minutes getting 57 words per minute.
the ratio of girls to boys in an astronomy club was 3:2. there were 30 girls. how many total members were there in the club
Answer:
Explanation: the ratio 2:4 can be reduced to 1:2, where the number of girls corresponds to the 1 and the number of boys corresponds to the 2. If there are 14 girls, then there must be 28 boys (14 x 2 = 28). Now to get the total number we need to add the total number of boys and girls together. So 14 + 28 = 42

Answer D 103,800
Answer:
D. $103800Step-by-step explanation:
Initial value of house:
$184000Yearly increase rate of value:
3.5%Time
13 yearsSince the increase is concerning the current price it would be exponential growth.
The function would be:
V(t) = 184000*(1 + 3.5/100)^t, where V is the value after t yearsFor t= 13 we get:
V(13) = 184000*(1.035)^13 = 287800Profit made would be:
287800 - 184000 = 103800Correct option is D.
Answer:
Cost of Tammy's house =$184000
Rate of interest = 3.5% per annum
After 13years price will be
[tex]P(t) = 184000 {(1 + \frac{3.5}{100}) }^{t} \\ P(t) = 184000 {(1 + 0.035)}^{t} \\ P(13) = 18400 {(1.035)}^{13} \\ P(13) =\$ 287768[/tex]
Total profit= $(287767-184000)= $103768

Three of the vertices of quadrilateral MARY are M (-3,1), A(3,3), and R(5,7). Find the
coordinates of Y, such that, quadrilateral MARY is a parallelogram.
Use coordinate geometry to prove that MARY is a parallelogram.
9514 1404 393
Answer:
Y = (-1, 5)
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, so have the same midpoint. That is ...
(M +R)/2 = (A +Y)/2
Y = M + R - A . . . . . . multiply by 2 and subtract A
Y = (-3, 1) +(5, 7) -(3, 3) = (-3 +5 -3, 1 +7, -3) . . . . . substitute point coordinates
Y = (-1, 5)
Coordinate geometry was used to find Y that makes MARY a parallelogram. The fact that there is a solution is proof enough that MARY is a parallelogram.

showing opposite sides have the same slopeshowing opposite line segments have the same lengthGiven the method used above, both of these are unnecessary. However, in the interest of completeness, we will demonstrate.
Slope and Length of MA
slope = (3 -1)/(3 -(-3)) = 2/6 = 1/3
length = √(2²+6²) = √40
Slope and Length of AR
slope = (7 -3)/(5 -3) = 4/2 = 2
length = √(4² +2²) = √20
Slope and Length of RY
slope = (5 -7)/(-1 -5) = -2/-6 = 1/3 . . . . same as opposite side MA
length = √((-2)²+(-6)²) = √40 . . . . . . . same as opposite side MA
Slope and Length of YM
slope = (1 -5)/(-3 -(-1)) = -4/-2 = 2 . . . . same as opposite side AR
length = √((-4)² +(-2)²) = √20 . . . . . . same as opposite side AR
Opposite sides have the same slopes, so the figure is a parallelogram.
Opposite sides have the same lengths, so the figure is a parallelogram.
a concert is attended by 2500 people. if 47% are adult females
and 32% are
adult males how many children attended?
Answer:
525 children attended the concert.
Step-by-step explanation:
Given that:
Total number of people who attended concert = 2500
Adult females = 47%
Adult males = 32%
Percent of children = (100-47-32)% = 21%
Number of children = 21% of people who attended
Number of children = [tex]\frac{21}{100}*2500[/tex]
Number of children = 0.21*2500 = 525
Hence,
525 children attended the concert.

My wife baked cookies this year. 40% of the cookies she baked were chocolate chip. If she baked 36 chocolate chip cookies, how many total cookies did she bake
Answer:
She baked 90 cookies.
Step-by-step explanation:
From the information given you know that 36 cookies represent 40% of the cookies that were baked. With this information, you can use a rule of three to find the total mount of cookies that she baked:
36 cookies → 40%
x ← 100%
x=(36*100)/40=90
According to this, the answer is that she baked 90 cookies.
By rounding each of 9.85, 3.875 and 6.3 to the nearest whole number work out an estimate for the answer to 9.85^3 / 3.875 + 6.3^2
Answer:
286.
Step-by-step explanation:
9.85^3 /3.875 + 6.3^2
= 10^3/ 4 + 6^2
= 1000/4 + 36
=250 + 36
=286.

What is the average rate change of a function?It is the average amount by which the function is modified per unit throughout that time period. It is calculated using the gradient of the line linking the interval's ends on the graph that represents the function. The average rate of change of the function is given as,
Average rate = [f(x₂) - f(x₁)] / [x₂ - x₁]
The function is given below.
f(x) = x² + 4x - 1
The average rate is calculated as,
Average rate = [f(3.1) - f(3)] / [3.1 - 3]
Average rate = [(3.1² + 4(3.1) - 1) - (3² + 4(3) - 1)] / 0.1
Average rate = (21.01 - 20) / (0.10)
Average rate = 1.01 / 0.10
Average rate = 10.1
Average rate ≈ 10
The approximate change in the value of the function will be 10. Then the correct option is C.

A triangle with angle measures thirty-nine degrees and one hundred two degrees. The third angle has an unknown measure, x degrees.
Answer:
x=39
Step-by-step explanation:
The sum of the measure of all of the interior angles of a triangle is equal to 180 degrees. If a triangle has angle measures known to be 102 and 39 degrees, in order to find the last angle measure an equation can be used such as [tex]x=180-102-39[/tex]. When solving this equation the third angle measure is x, which is revealed to be 39 degrees.
