Answer:

Distance of Tunnel is 500 meters + Train travel rate is 20 meters per second = 25 seconds to pass through the tunnel only therefore the outstanding balance of 35 seconds x 20 meters per second =600 meters Train

Step-by-step explanation:

Total of length of train 600 meters and tunnel (500 meters) is 1,200 meters +30 seconds = TR of 20 meters per second

Answer:

V≈83.78

Step-by-step explanation:

The formula to find the volume of a cone is V=πr(squared) h/3

Steps

V= π (4)^2  5/3

V= π (16)  1.66666666667

V = 50.2654824574 * 1.66666666667

v= 83.7758040958

Round

V = 83.78

Answer:

The volume of cone is 83.73m³.

Step-by-step explanation:

To find the volume of the cone we use Formula:

[tex] \sf V = \frac{1}{3} \pi {r}^{2} h \\ \\ \implies \: \frac{1}{3} \times 3.14 \times {4}^{2} \times 5 \\ \\ \implies \frac{1}{3} \times 15.70\times 16 \\ \\ \implies \: \frac{1}{ \cancel3} \times \cancel{251.20} \\ \\ \implies \sf \pink{83.73 {m}^{3} }[/tex]

Hence, the volume of cone is 83.73m³.

Answer:

22

Step-by-step explanation:

You can just use the previous terms to derive the 4th term.

3rd term: 4(2) + 2 = 10

4th term: 10(2) + 2 = 22

The 4th number in the pattern is 22 .

A pattern is a repeated arrangement of numbers, shapes, colors and so on. The Pattern can be related to any type of event or object. If the set of numbers are related to each other in a specific rule, then the rule or manner is called a pattern. Sometimes, patterns are also known as a sequence.

According to the question

Mrs. Johnson asked to form a number pattern using these rules.

rule1: Use the number 1 as the first term.

rule2:To find any other term, double the previous term and add 2

and The first two numbers in the pattern are 1 and 4

therefore ,

First term : 1

Second term : 4  (1*2+2)

Third term :   10    (4*2+2)

Fourth term :  22   (10*2+2)

Hence, the 4th number in the pattern is 22 .

Answer:

  (b)  y = 4x +15; y = 10x -2

Step-by-step explanation:

It is often sufficient to check for reasonableness in the offered answers. That is the case here.

__

The offered answer choices differ in the combinations of slope. The offered slopes (x-coefficients) are 4 or 1/4, 10 or 1/10, so it is sufficient to determine if the slope is greater than 1 in each case.

The slope is the ratio of the change in y to the change in x. It will be greater than 1 if y changes by a larger number than x does.

x-values in this table change by 4-2 = 2. y-values change by 31 -23 = 8, which is more than 2. The slope is greater than 1 for the first equation. (It is 8/2 = 4.)

The first two x-values in this table differ by 0-(-1) = 1. The first two y-values differ by -2-(-12) = 10, which is more than 1. The slope is also greater than 1 for the second equation. (It is 10/1 = 10.)

The x-coefficients in the answer choices are ...

  a) 1/14, 1/10 . . . incorrect

  b) 4, 10 . . . . correct

  c) 1/4, 10 . . . . partly correct

  d) 4, 1/10 . . . . partly correct

Answer:

The trapezoids and the irregular figures at the top left.

Step-by-step explanation:

Congruent means "in agreement or harmony." So that means in math congruent means "the same" and the trapeziods were both the same and so were the irregular figures.

Answer:

1/12

Step-by-step equation

Since your spinning a spinner twice which has a chance of landing on any number with a 1/6 chance spinning a number than q would give you a 1/12 chance. Another equation would be 1/6 * 2

If each side of the case is three times longer than the width of the pyramid that means we would do (wx3)^3 as to find the volume of a perfect cube we do to the power of 3.

Answer:

199.51$

Step-by-step explanation:

10 x 12 = 120$

25 x 5 = 125$

5 x 8 = 40¢

1 x 11 = 11¢

30 + 50 = 80$

120$ + 125$ + 40¢ + 11¢ + 80$ = 325.51$

325.51$ - 44$ = 281.51$ - 25$ = 256.51$ - 12$ = 244.51$ - 15$ = 229.51$ - 30$ = 199.51$

Answer:

12x - 14y cubic yards

Step-by-step explanation:

a keyword in this is... difference

it also asks you to compare the first truck to the second truck not the second to the first

x = the amount of mulch the first truck can deliver

y = the amount of mulch the second truck can deliver

the first truck takes 12 trips so 12 trips multiplied by x (the amount of mulch the first truck can deliver) is 12x because it doesn't give us x

the second truck takes 14 trips so 14 trips multiplied by y (the amount of mulch the second truck can deliver) is 14y because it doesn't give us y

The question asks for the difference between the total number of cubic yards that the first truck carries through their 12 trips and the total number of cubic yards that the second truck carries through their 14 trips.

This gives us, 12x - 14y cubic yards

hopefully, this makes sense :)

Answer: x^2+5

Step-by-step explanation:

x is the unknown variable which is representing the number squared and then you add 5 to complete expresssion.

Answer:

x² + 5

Step-by-step explanation:

Given statement:

We know the following:

    1. "number squared" ⇒ A number multiplied to the same number.

    Let the number be known as "x". Then;

        [tex]\implies x \times x[/tex]

        [tex]\implies \underline{x^{2}}[/tex]

   2. "added to 5" ⇒ Addition between number, squared and 5.

   Let the number be known as "x". Then;

        [tex]\implies (x)^{2} + 5[/tex]  [tex](\text{number, squared} \implies x^{2} )[/tex]

        [tex]\implies \boxed{x^{2} + 5}[/tex]

Therefore, the expression that represents the statement is x² + 5.

Answer:

84 months

Step-by-step explanation:

Maria is 7 years old, there are 12 months in a year, multiply 12 by 7.

12 * 7 = 84

Maria is 84 months old

Answer:

Maria is 84 months old.

Multiply the years(y) by every 12 months that pass(m).

[tex]y * m = 84[/tex]

note that y is 7, and m is 12, because we count every 12 months that pass for 7 years.
