Writing a check takes money out of the bank account. Subtract the amount of the check from the amount in the account:
64 - 87 = -23
They would have -$23 in the account
A diving board is 10 feet above the surface of the water. At time t = 0, the board propels Chris upward at a rate of 12 feet per second and he enters the water feet first. The equation h = –16t^2 + 12t + 10 can be used to find Chris's height after t seconds. How long will it take Chris to return to his starting height of 10 feet?
Answer:
Chris will take 0.75 seconds to return to his starting height of 10 feet.
Step-by-step explanation:
Let the height of Chris be represented by [tex]h(t) = -16\cdot t^{2}+12\cdot t +10[/tex], where [tex]h(t)[/tex] is the height in feet and [tex]t[/tex], the time in seconds. First, we equalize the formula to a height of 10 feet and simplify the resulting expression, that is:
[tex]-16\cdot t^{2}+12\cdot t +10 = 10[/tex]
[tex]-16\cdot t^{2}+12\cdot t = 0[/tex]
Then, we simplify the expression by algebraic means:
[tex]-16\cdot t\cdot \left(t-\frac{3}{4} \right) = 0[/tex]
Roots of the polynomial are, respectively:
[tex]t = 0\,s\,\lor \,t = 0.75\,s[/tex]
First root represents the initial height of Chris, whereas the second one represents the instant when Christ returns to the same height above the surface of the water. Hence, Chris will take 0.75 seconds to return to his starting height of 10 feet.

The Davis family is going to reseed the grass in the backyard. Their yard is irregularly shaped with a cement patio and rectangular garden as shown below.
Given that the family will not need grass seed for the patio or the garden areas, what is the total area of the land will they be reseeding?
Answer:
1,482 square feet
Step-by-step explanation:
Find total area - 37 x 46 = 1,702
Find area of patio and garden - 16 x 10 = 160 for the patio, 12 x 5 = 60 for the garden
Subtract from total area - 1702 - 160 = 1542, 1542 - 60 = 1,482 sq ft

Kayla and Josh are watching marathons of their favorite TV show. Episodes of Kayla's show are 120 minutes long, while episodes of Josh's show are 135 minutes long. If they start their TV binge at the same time, how many minutes will it be before they start another episode at the same time?
9514 1404 393
Answer:
1080 minutes
Step-by-step explanation:
The greatest common factor (GCF) of the two times is 15 minutes, so their least common multiple is (120×135)/15 = 1080 minutes.
In that time, Kayla will have watched 9 shows, and Josh will have watched 8.
It will be 1080 minutes before they start again at the same time.

Jonah took out a four year loan for $22,000 to help pay for college. He has to pay 5% simple interest on the loan. How much will he have to pay back at the end of the four years?
Answer:
26,400
Step-by-step explanation:
1) Find 5% of 22,000 by multiplying 22,000 by .05. You should get 1100.
2) Multiply that by 4. (4400)
3) Now add that to the original.
From a boat ont he lake, the angle of elevation to the top of a cliff is 11° 50'. If the base of the cliff is 1568 feet from the boat, how high is the cliff (to the nearest foot)
Answer:
328 feet
Step-by-step explanation:
From a boat ont he lake, the angle of elevation to the top of a cliff is 11° 50'. If the base of the cliff is 1568 feet from the boat, how high is the cliff (to the nearest foot)
Step 1
Note that
that 11°50' is just 11 degrees and 50 minutes
60 minutes = 1 degree,
thus 50 minutes = x degree
50/60 degrees
= 0.83°
Hence: 11°50' = 11.83°.
Step 2
We solve using Trigonometric function of tan
tan theta = Opposite/Adjacent
theta = 11.83°
Adjacent = 1568 feet
Opposite = Height of the cliff = x
tan 11.83° = x/1568
Cross Multiply
x = tan 11.83 × 1568
x = 328.429195 feet
Approximately = 328 feet
The height of the cliff is 328 feet
What is the area of polygon ABCDE?
Need answers ASAP!
Will give brainliest if possible!!
Answer:
66 cm
Step-by-step explanation:
You can find the area of the rectangle by simply multiplying the sides that are complete and don't touch the triangle. That is equal to 60 cm.
To find the area of the triangle, you first have to find the sides. You can find the first side by subtract the top side of the rectangle from the bottom, which gets us 3 (12-9). Then subtract the left side (5) from the right side (9) (9-5), which gets us 4. That would mean that 3*4*1/2 is equal to 6. 6+60 is equal to 66 cm.
Hope that this helps!
A contest gives out prizes for first, second, and third place. First place is $500 more than double third place. Second place is $400 less than first place. All together, $1850 is given out in prizes. How much is each prize worth?
9514 1404 393
Answer:
$1000$600$250Step-by-step explanation:
Let t represent the third-place prize value. Then the first place prize has a value of 2t+500, and the second-place prize is 2t+100. The total value of the three prizes is ...
t +(2t+500) +(2t+100) = 1850
5t +600 = 1850
5t = 1250
t = 250 . . . . . . . . . . . third place prize
2t +500 = 1000 . . . . first place prize
1000 -400 = 600 . . .second place prize
The prizes for 1st, 2nd, and 3rd places are $1000, $600, and $250, respectively.

Determine the length of the rectangle if the area is 800 cm² and the breadth is 20 cm
Answer:
40 cm
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lb ( l is the length and b the breadth )
Here b = 20 and A = 800 , then
l × 20 = 800 ( divide both sides by 20 )
l = 40 cm
Solve
−2(x+8)+6=7(x−3) for x algebraically. If your answer is a fraction, write it in reduced, fractional form. Do NOT convert the answer to a decimal.
Answer:
x = 11/5
Step-by-step explanation:
-2x - 16 + 6 = 7x - 21
5x - 21 = -10
5x = 11
x = 11/5
Answer:
x = 11/9
Step-by-step explanation:
-2(x + 8 ) + 6 = 7(x - 3) {Use distributive property: a(b +c)= a*b +a*c) }
-2x + 8*(-2) + 6 = 7*x - 3*7
-2x - 16 +6 = 7x - 21 {add 2x to both sides}
-10 = 7x + 2x - 21
-10 = 9x - 21 {add 21 to both sides}
-10 + 21 = 9x
11 = 9x {divide both sides by 9)
11/9 = x

Answer:
y = -2/3x + 1
Step-by-step explanation:
( -3, 3) and (0,1)
m=(y2-y1)/(x2-x1)
m=( 1 - 3)/(0+3)
m = (-2)/3
m = -2/3
y - y1 = m(x - x1)
y - 3 = -2/3(x + 3)
y - 3 = -2/3x - 2
y = -2/3x + 1
Answer:
y = -2/3x + 1
Step-by-step explanation:
(-3,3) and (0,1)
slope= y2-y1/x2-x1
1-3 / 0+3
-2/3
y = mx + b
y = -2/3x + b
1 = 0 + b
b = 1
y = -2/3x + 1
