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

To find the answer we will add both percentages of Watching TV and Homework. 8% + 13% = 21%. Now we will divide 100 by 21 and we get 4 hours a day.
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.

What is the product?
(9t - 4)(-9 t - 4)
negative 81 t squared minus 16
negative 81 t squared + 16
negative 81 t squared minus 72 t + 16
negative 81 t squared + 72 t + 16
Answer:
The product is -81 t² + 16
Step-by-step explanation:
The product of two binomials (ax + b)(cx + d), where a, b, c, and d are constant
Multiply (ax) by (cx) ⇒ 1st × 1st
Multiply (ax) by (d) and (b) by (cx) ⇒ ext-reams and nears
Add the two products ⇒ like terms
Multiply (b) by (d) ⇒ 2nd × 2nd
Let us find the product of (9 t - 4) and (-9 t - 4)
Multiply the 1st two terms
∵ (9 t)(-9 t) = -81 t²
Multiply the ext-reams
∵ (9 t)(-4) = -36 t
Multiply the nears
∵ (-4)(-9 t) = 36 t
Add the like terms
∵ -36 t + 36 t = 0
Multiply the 2nd two terms
∵ (-4)(-4) = 16
Write the answer
∴ (9 t - 4)(-9 t - 4) = -81 t² + 0 + 16
∴ (9 t - 4)(-9 t - 4) = -81 t² + 16
The product is -81 t² + 16

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.

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

On Thursday Mia ran 1 5/10 miles Rashid ran 2 4/5 miles how many fewer miles did Mia run than Rashid.
Answer:
[tex]1\frac{3}{10}[/tex]
Step-by-step explanation:
We are to determine the difference between the miles ran by Mia and Rashid.
[tex]2\frac{4}{5}[/tex]- [tex]1\frac{5}{10}[/tex]
Subtract the two whole numbers
divide each denominator by the least common multiple and multiply the figures by the numerator
[tex]1\frac{8-5}{10}[/tex] = 1[tex]\frac{3}{10}[/tex]
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
