Answer:

[tex]\text{C. }156\:\mathrm{cm^3}[/tex]

Step-by-step explanation:

The surface area of the triangular prism consists of three rectangles and two triangles.

Rectangle One - 5 x 12 = 60 cm^2

Rectangle Two - 4 x 12 = 48 cm^2

Rectangle Three - 3 x 12 = 36 cm^2

Triangles - 2 x 1/2 x 3 x 4 = 12 cm^2

Thus, the total surface area of the solid is [tex]60+48+36+12=\boxed{\text{C. }156\:\mathrm{cm^3}}[/tex]

Answer:

1)9/3 yint 9 2)3/1 yint 7 3)1/1 yint 5

Answer:

[tex]volume \ of \ sphere = \frac{4}{3} \pi r^3 \\\\1 =\frac{4}{3} \pi r^3\\\\r^ 3 = \frac{3}{4\pi} \\\\r = (\frac{3}{4\pi })^{\frac{1}{3} } \\\\r = 0.62ft\\\\diameter = 2 * 0.62 = 1.24ft[/tex]

Answer:

1.24 ft

Step-by-step explanation:

the volume of sphere = 4/3π.r³ = 1

=> r³ = 3/(4π)= 3/(12.56) = 0.239

r = ³√0.239

r = 0.62

d = 2×0.62 = 1.24 ft

Answer:

Step-by-step explanation:

solution:

            Data,

                      driving speed of car intially velocity at = Vi = 60km/h

                      the speed was then raised to final velocity at = Vf = 70km/h

                       the total period of speed raised = t = 5 sec

            Req,    acceleration = ?

                     put the formulae :  a =  Vf - Vi/t

                            a = 70 - 60/5

                             a =  2 m/sec2 ans

Answer:

GARDEN = 9 years

TREE = 99 years

Step-by-step explanation:

the following equation can be derived from the question

age of oak tree = 11x

age of garden = x

11x + x = 108

12x = 108

x = 9

oak tree = 11 x 9 = 99

Answer:

70.8°

Step-by-step explanation:

From the triangle,

We are given the hypotenus and the angle opposite θ

Using Trigonometry:

Hypotenus and opposite are related by :

Sinθ = opposite / hypotenus

Sinθ = 17 / 18

θ = sin^-1(17/18)

θ = 70.811°

θ = 70.8°

Answer:

Mean = 4.7

Mode = 5

Median = 5

Step-by-step explanation:

Mean = Σfx / Σf

Σfx = (3*4) + (4*5) + (5*7) + (6*2) + (7*2) = 93

Σf = (4+5+7+2+2) = 20

Mean = 93 / 20

= 4.65

= 4.7

Mode = highest occurring = vlaue with highest frequency = 5

Median :

20 / 2 = 10

Value corresponding to the 10th term = 5

Answer:

960cm³

Step-by-step explanation:

Find the base of the triangle (use phytagoras theorem)

c²= a²+b²

20²= 16²+b²

400=256+b²

b²=400-256

b²= 144

b=

[tex] \sqrt{144} [/tex]

base= 12

Volume: (1/2×b×h)×l

= (1/2×12×16)×10

=(6×16)×10

=96×10

=960cm³

Answer:

[tex]A) x+y=100 \\ ..\ 5x + y = 420[/tex]

Step-by-step explanation:

From the question we are told that:

Five-dollar bill  x

One-dollar bill  y

Total number of bills [tex]N=100[/tex]

Worth of bills [tex]w=420[/tex]

Generally the equation for Total number of bills  is mathematically given by

Since it is made up of five and one dollar bills

Therefore

  [tex]x+y=100[/tex]

Hence the Equation for Total worth of bills is

 [tex]5x+y=420[/tex]

The System of equations used is

[tex]A) x+y=100 \\ ..\ 5x + y = 420[/tex]

Answer:

The website ends in gov, the purpose of the webpage is to educate and not make money

Step-by-step explanation:

Hi kiri ☺️

Credible websites are those which are not biased and supposed to help the people without the intention of making money.

Answer: I’m pretty sure it’s A but I could be wrong

Step-by-step explanation:

Numerator is the top and there are 12 fruit and 7 apple so the top number should be 7 and the bottom should be 12

Answer:

Option A. –2 – 2√2

Step-by-step explanation:

√8 / √2 – 2

The above expression can be simplified as follow.

√8 / (√2 – 2)

Rationalise by multiplying the numerator and denominator with the conjugate of (√2 – 2) i.e (√2 + 2). This is illustrated below:

√8 / (√2 – 2) × (√2 + 2)/(√2 + 2)

√8(√2 + 2) / (√2 – 2)(√2 + 2)

√16 + 2√8 / 2 + 2√2 – 2√2 – 4

√16 + 2√8 / 2 – 4

√16 + 2√8 / –2

Recall

√16 = 4

√8 = √(4×2) = √4 × √2 = 2√2

Thus,

√16 + 2√8 / –2 = 4 + 2×2√2 / –2

= (4 + 4√2) / –2

= 4/–2 + 4√2/–2

= –2 – 2√2

Therefore,

√8 / (√2 – 2) = –2 – 2√2

Thus, option A gives the correct answer to the question.

Answer:

A. 10 km/h

B. 6 kilometers into the race

Step-by-step explanation:

Read from the graph.

The x-axis (along the bottom) is the distance in kilometers.

The y-axis (going up) is the speed in km/h.

A. Reading from the x-axis at 8, go up until you reach the line. Read to the left and we get 10 km/h.

B. Look at which point is the highest. Which is at 12 km/h where he was 6 km into the race.

Answer:

(D) H_0H0​: The direction of the ball and whether it results in a hit or an out are independent.

Step-by-step explanation:

Given that

There is 300 balls random sample is taken

We need to find out the appropriate null hypothesis that lies between the ball direction and lead to a hit or an out

So

Based on the given options, the option d is correct as the ball direction and its results either be hit or on out would represent that they are independent

Therefore the option d is correct

Answer:

sum of money(principal)=rs5000

amount=rs8750

rate=15%

to find interest use forrmula,

amount=principal+interest

rs8750=rs5000+interest

rs8750-rs5000=interest

rs3750=interest

to find time use formula,

interest=p*t*r/100

rs3750=rs5000*t*15/100

rs3750*100=rs75000*t

rs375000/rs75000=t

5=t

Step-by-step explanation:

therefore the sum of money rs5000 amount to rs8750 at the rate of 15% after 5 years

Answer:

Answer:

[tex]P = (2,-3)[/tex]

Step-by-step explanation:

Given

[tex]m : n = 3 : 2[/tex]

[tex]A = (8,6)[/tex]

[tex]B = (-2,-9)[/tex]

Required

The coordinate of {

This is calculated as:

[tex]P = (\frac{mx_2 + nx_1}{m + n},\frac{my_2 + ny_1}{m + n})[/tex]

So, we have:

[tex]P = (\frac{3*-2 + 2*8}{3 + 2},\frac{3*-9 + 2*6}{3 + 2})[/tex]

[tex]P = (\frac{10}{5},\frac{-15}{5})[/tex]

[tex]P = (2,-3)[/tex]
