Hello! answer: 544

Hope this helps!

The surface area of the given triangular prism is 544 units³

What is a triangular prism?

A triangular prism is a polyhedron made up of two triangular bases and three rectangular sides.

Given that are the dimensions of a triangular prism, we are asked to find its surface area,

Surface area = (perimeter × length)+(base area)

Surface area = [(10+10+12)×14]+(8×12)

= 32×14+96

= 448+96

= 544

Hence, the surface area of the given triangular prism is 544 units³

Javier estimates the square root of 18 in the following way:

18−−√=29–√=2∗3=6
18=29=2∗3=6



Explain why her reasoning is incorrect.

Without using a calculator, the square root of 18 will be between what two values (remember to look for perfect squares/perfect square roots)? Show your reasoning. You do not need to find the decimal equivalent of the root.

Answers

Answer:

The square root will be about 4 because the formula for square root is √(x^2) = x

Step-by-step explanation:

Answer:

√18 = √(2x9) = 3√2. so they pulled the 2 out of the square root incorrectly.

4x4 = 16

5x5 = 25

so √18 is between 4 and 5. closer to 4

Step-by-step explanation:

- 4(y-2) = 12

What’s the value of x?

Explain

Answers

Answer:

There is no x, so I’ll find y

Step-by-step explanation:

-4(y-2)=12

Multiply -4 with y and -2

-4y+8=12

Then subtract 8 with its self and 12

-4y = 4

now divide both numbers with 4

y= -1

Step 1. Multiply -4 by y.... you get -4y
Step 2. Multiply -4 by -2.... you get 8
Step 3. Equation will be -4y+8=12
Step 4. Subtract 8 from 8 and 12
Step 5. Equation will be -4y=4
Step 6. Divide 4 by both sides
Step 7. Answer is y=-1

Question 5: The missing term her is r²

Question 6: The missing term here is 3.

Step-by-step explanation:

Question 5:

Let's write the equation and then solve it for the missing term. We will call this term x.

[tex](6r^{4}+4r)+(x-2r^{4}+3r)=4r^{4}+r^{2}+7r[/tex]

First, we simplify the letf term adding the similar terms.

[tex]x+4r^{4}+7r=4r^{4}+r^{2}+7r[/tex]

Now, we substract 4r⁴ and 7r in both sides.

[tex]x=r^{2}[/tex]

Therefore, the missing term her is r²

Question 6:

Here, we will call the missing term y. Now, let's solve it for y.

[tex](y-8x-x^{2})-(4x^{2}-7+6x)=-5x^{2}-14x+10[/tex]

Let's first distribute the minus sign into the parentehsis.

[tex]y-8x-x^{2}-4x^{2}+7-6x=-5x^{2}-14x+10[/tex]

Now simplify the left side by adding similar terms.

[tex]y-14x-5x^{2}+7=-5x^{2}-14x+10[/tex]

Now, let's add 14x and 5x² on both sides, then subtract 7 on both sides.

[tex]y=10-7[/tex]

[tex]y=3[/tex]

Therefore, the missing term here is 3.

A family has two cars. The first car has a fuel efficiency of 20 miles per gallon of gas and the second has a fuel efficiency of 40 miles per gallon of gas. During one particular week, the two cars went a combined total of 1100 miles, for a total gas consumption of 35 gallons. How many gallons were consumed by each of the two cars that week?

Answers

Answer:

Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.

Step-by-step explanation:

fuel efficiency = distance in miles/gallons of gas

fuel efficiency * gallons of gas = distance in miles

Car 1: 20 mpg

Car 2: 40 mpg

Total miles: 1100

Miles of Car 1: x

Miles of Car 2: 1100 - x

Total gallons: 35

Gallons for Car 1: y

Gallons for Car 2: 35 - y

Car 1:

fuel efficiency * gallons of gas = distance in miles

20 * y = x

Car 2:

fuel efficiency * gallons of gas = distance in miles

40 * (35 - y) = 1100 - x

20y = x

1400 - 40y = 1100 - x

20y = x

x = 40y - 300

40y - 300 = 20y

20y = 300

y = 15

35 - y = 35 - 15 = 20

Car 1 consumed 15 gallons, and Car 2 consumed 20 gallons.

A cylindrical pipe is 25 ft long and has a volume of 900ft3 find it's approximate diameter to the nearest hundredth of a foot

Answers

Answer:

Diameter of the pipe ≈ 6.77 ft

Step-by-step explanation:

Volume of a cylinder = πr²h

Here, r = Radius of the cylindrical pipe

h = Length of the pipe

Volume of the pipe = 900 ft³

Length of the pipe = 25 ft

By substituting the given values in the formula,

900 = π(r)²(25)

r² = [tex]\frac{900}{25\pi}[/tex]

r = √11.459

r = 3.385

Diameter = 2(radius)

                = 2(3.385)

                = 6.77 ft

The diameter of the cylinderi is 6.77ft

Volume of a cylinder

the formula for calculating thevolume of a cylinder is given as

V = pi d²/4 × h

Given the following

V = 900ft³

h = 25ft

Substitute the given parameters

900 = 3.14 × d²/4 × 25

900 = 19.625d²

d² = 45.859

d = 6.77ft

Hence the diameter of the cylinderi is 6.77ft

A car that is purchased got 24000 is expected to depreciate at a rate of 7% per year. If the function f(x)=ab^x models this situation, which function could be used to find the value of the car after 10 years?

Answers

Answer:

FV= 24,000*(1.07^-10)

Step-by-step explanation:

Giving the following information:

Present Value (PV)= $24,000

Decrease rate (d)= 7%

Number of periods (n)= 10 years

To calculate the value of the car after 10 years, we need to use the following formula:

FV= PV*(1+d)^-n

FV= 24,000*(1.07^-10)

FV= $12,200.38
