Answer:

l = 104/3

w = 40/3

Step-by-step explanation:

l = 2*w + 8

P = 2(l + w) = 96

48 = l + w

2w + 8 + w = 48

3w = 40

w = 40/3

l = 2*40/3 + 8

= 80/3 + 8

= 80 + 24 / 3

= 104/3

The teachers had to transport 165 students by bus on a field trip. Each bus holds 64 students. How many buses do they need to order?

Answers

Answer:

Step-by-step explanation:

Divide the number of students by the capacity of each bus

. 165 / 64 = 2 (busses) + 37/64 (remainder)

given:

165 students

each bus= 64 students

to find:

how many buses they need to order in order to take 165 students.

solution:

[tex] \frac{165}{64} [/tex]

[tex] = 2.578125[/tex]

[tex] = 2 \frac{37}{64} [/tex]

hence, the correct answer is option B.

Give your answer correct to 2 decimal places

Answers

Answer:

A=density=1.42g/cm^3

mass=9.94g

volume=7cm^3

B=density =?

mass=128.66g

volume=125cm^3

C=density=108g/cm^3

mass=138.6g

volume=132cm^3

massA 1.42×7=9.94g

massB 138.6-9.94=128.66g

massC 132×1.05=138.6g

Density of B =mass/ volume

=126.66÷ 125

A pool with a square bottom is to have a volume of 2000 cubic feet. The owners plan to use a fancy tile to complete the pool. The sides of the pool will cost $80 per square foot and the bottom of the pool will cost $40 per square foot. Find the pool dimensions that will minimize the cost of construction.

Answers

Considering the given conditions in the question, the dimensions that will minimize the cost of construction of the pool are:

base length = 10 feet

base width = 10 feet

pool depth = 20 feet

Volume of a material implies the maximum amount of substance that it can contain.

From the given question, it is expected that the pool would have the shape of a cuboid, thus its volume can be determined by:

volume of the pool = length x width x height

= base area x height

Thus, given that the volume of the pool is 2000 cubic feet, then;

2000 = base area x height

i. Let the dimensions of the square base be 10 feet, and its height 20 feet, so that;

volume = 10 x 10 x 20

= 2000 cubic feet

The cost of constructing the pool of the assumed dimensions would be:

Total area of its sides = 4 x 200

= 800 square feet

The cost of tiling the sides of the pool = $80 x 800

= $ 6400.0

Area of the base of the pool = 10 x 10

= 100 square feet

The cost of tiling the base of the pool = $40 x 100

= $4000

Total cost = $6400 + $4000

= $10400

Total cost of constructing the pool with the assumed dimensions is $10400.

ii. Let the dimensions of the square base be 20 feet, and its height 5 feet, so that;

volume = 20 x 20 x 5

= 2000 cubic feet

The cost of constructing the pool of the assumed dimensions would be:

Total area of its sides = 4 x 100

= 400 square feet

The cost of tiling the sides of the pool = $80 x 400

= $ 32000

Area of the base of the pool = 20 x 20

= 400 square feet

The cost of tiling the base of the pool = $40 x 400

= $16000

Total cost = $16000 + $32000

= $48000

Total cost of constructing the pool with the assumed dimensions is $48000.

Therefore, the dimensions that will minimize the cost of construction of the pool are:

base length = 10 feet

base width = 10 feet

pool depth = 20 feet

Find the perimeter.simplify your answer.

Answers

The perimeter of a shape is the sum of its side lengths.

The perimeter of the shape is 24z - 18

Represent the length with l and the width with w.

The dimensions are given as:

[tex]l = 10z[/tex]

[tex]w = 2z - 9[/tex]

So, we have:

[tex]P =2 \times (l + w)[/tex] --- the formula of perimeter

The above equation becomes

[tex]P = 2 \times (10z + 2z - 9)[/tex]

Evaluate like terms

[tex]P = 2 \times (12z - 9)[/tex]

Open brackets

[tex]P = 24z - 18[/tex]

Hence, the perimeter of the shape is 24z - 18

A line passing through the point(-10,-5) and has a slope of -1/2

Answers

y = -1/2x - 10

ex : -10 is x, -5 is y, -1/2 is slope

y = mx + b, m is slope, solving for b (y-intercept)

-5 = -1/2(-10)+b
-5 = 5 + b

try to get b by itself, so minus the positive 5

-5-5 = b, so -10 = b

which leads to y = -1/2x - 10

Answer:

<AMC=75°

Step-by-step explanation:

if <C=90 and <B = 30, then <A=60 (because <A+<B+<C=180, as ABC is a triangle)

if CM is a angle bisector then it divides <C in half, so <ACM=<MCB=45

since <ACM=45;

<A = 60;

then <AMC = 180-(45+60),

<AMC = 180-105,

<AMC = 75.
