Answer:

144 m^3

Step-by-step explanation:

Please find attached the image of the prisms

Volume of a triangular prism = area of the base x height  of the prism

Area of the base = 1/2 ( base x height)

the two prisms are similar, thus, the dimensions of the bigger rectangle can be gotten from the ratio of the base of the smaller and bigger triangle

ratio of their dimensions = 6 / 1.5 = 4

the dimensions of the bigger triangle is 4 times that of the smaller triangle

height of the base of the prism = 1.5 x 4 = 6

Height of the prism = 2 x 4 = 8

Area of the base of the prism = (1/2) x 6 x 6 = 18 m^2

Volume of the prism = 18 x 8 = 144 m^3

D. 144 m^3

Just took the Pre-Test on Edg (2020-2021)!!

Answer:

x = 5 or -1

We reject the second answer of x = -1

This is because upon substituting, it will give a negative number which the logarithm value of a negative number is not obtainable

So our only correct answer here is x = 5

Step-by-step explanation:

From the logarithmic rules;

log a - log b = log (a/b)

Applying this here, we have;

log4(x^2-4/4x+ 1) = 0

(x^2-4)/(4x+ 1) = 4^0

(x^2-4)/(4x + 1) = 1

x^2 -4 = 1(4x + 1)

x^2 -4 = 4x + 1

x^2 - 4x -4-1 = 0

x^2 -4x -5 = 0

x^2+ x -5x -5 = 0

x(x + 1) -5(x + 1) = 0

(x-5)(x + 1) = 0

x = 5 or -1

Answer:

The value of t is 53

Answer: [tex]10\ cm^3[/tex]

Step-by-step explanation:

Given

The surface area of a rectangular prism is [tex]34\ cm^2[/tex]

Width of prism [tex]w=1\ cm[/tex]

Length of prism [tex]l=2\ cm[/tex]

height of prism [tex]h=x\ cm[/tex]

Surface area is given by

[tex]S.A.=2[lw+wh+hl][/tex]

Put values

[tex]34=2[2\times 1+1\times x+2x]\\17=2+3x\\15=3x\\x=5\ cm[/tex]

Now, the volume of Prism is given by

[tex]V=l\times w\times h[/tex]

[tex]\Rightarrow V=2\times1\times 5=10\ cm^3[/tex]

Give Brainllest plz

Answer:

5

Step-by-step explanation:

this can be solved using simultaneous equation

2a + 3b = 19  equation 1

1a + 4b = 17    equation 2

Multiply equation 2 by 2

2a + 8b = 34  equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

Step-by-step explanation:

2a + 3b = 19 equation 1

1a + 4b = 17 equation 2

Multiply equation 2 by 2

2a + 8b = 34 equation 3

Subtract equation 1 from 3

5b = 15

b = 3

Substitute for b in equation 1

2a + 3(3) = 19

2a = 9 = 19

2a = 10

a = 5

Answer:

6000 miles

Step-by-step explanation:

1 in = 1500 miles

4 in = ___ miles

We simply just multiply 1500 and 4

1500 x 4 = 6000

4 in = 6000 miles

Answer:

y=-4.2

Step-by-step explanation:

2.9=7.1+y

2.9-7.1=7.1-7.1 +y

-4.2=y or y= -4.2

y = -4.2

If you substitute that value for y into the equation, you'll get 2.9 = 7.1 + (-4.2)... and that is a correct, valid equation. HOPE THAT HELPS!

Answer:

Step-by-step explanation:

For the first 30 hours, Andrew will earn 4(30) = $120.  For each additional hour beyond 30 that Andrew works, he will earn 5(h - 30).  Therefore, the function that gives Andrew's total wages when he works more than 30 hours is:

w = 120 + 5(h - 30).  

So, if he works 35 hours, he will earn:

120 + 5(35 - 30) = 120 + 5(5) = 120 + 25 = $145.

If he works 42 hours, he will earn:

120 + 5(42 - 30) = 120 + 5(12) = 120 + 60 = $180.

I hope this helps!

Step-by-step explanation:

Given

[tex]ABD = 0.18x +67[/tex]

[tex]CBD = 0.07x + 48[/tex]

Required

Find x

The question is incomplete as the relationship between ABD and CBD is not stated.

Assume ABD = CBD

The solution is:

[tex]0.18x + 67 = 0.07x + 48[/tex]

Collect like terms

[tex]0.18x - 0.07x= - 67 + 48[/tex]

[tex]0.11x= -19[/tex]

Solve for x

[tex]x = -\frac{19}{0.11}[/tex]

[tex]x = -172.72[/tex]

Assume ABD and CBD are supplementary

The solution is:

[tex]ABD + CBD=180[/tex]

[tex]0.18x + 67 + 0.07x + 48 = 180[/tex]

Collect like terms

[tex]0.18x + 0.07x = - 48 - 67 + 180[/tex]

[tex]0.25x = 65[/tex]

Solve for x

[tex]x = \frac{65}{0.25}[/tex]

[tex]x = 260[/tex]

Assume ABD and CBD are complementary

The solution is:

[tex]ABD + CBD=90[/tex]

[tex]0.18x + 67 + 0.07x + 48 = 90[/tex]

Collect like terms

[tex]0.18x + 0.07x = - 48 - 67 + 90[/tex]

[tex]0.25x = -25[/tex]

Solve for x

[tex]x = \frac{-25}{0.25}[/tex]

[tex]x = -100[/tex]

Answer:

162, sorry if this is wrong

Step-by-step explanation:

Answer and Step-by-step explanation:

Yes, all of your calculations are correct!!

The area of one rectangle is 192, and since there are 2 rectangles, we multiply 192 by 2, which results in 384.

The area of a triangle is [tex]A = \frac{(Height)(Base)}{2}[/tex], which you got to be 96.

The Semi Circle would have half of the area of a circle, so you are correct when you multiply the equation by [tex]\frac{1}{2}[/tex].

To find that diameter, we need to use the Pythagorean Theorem.

[tex]12^{2} + 16^{2} = d^{2} \\\\144 + 256 = d^{2} \\\\400 = d^2\\\\d = 20[/tex]

So the diameter is 20, and the radius is 10 (20 divided by 2 = radius).

Plug that into the equation, and you get the answer to be [tex]50\pi[/tex], or 157.0796327.

157.0796327 + 384 + 96 = 637.08 (rounded to the nearest hundredth).

Good job!

Answer:

For every 7 books Ethan read, Sadie read 3 books.

Step-by-step explanation:

For every 21 books Ethan read, Sadie read 9 books.

Unsimplified Ratio = 21:9

21 and 9 have a common factor of 3.

Because 21 and 9 share a common factor we can simplify the ratio

21 / 3 = 7

9 / 3 = 3

The new ratio is 7 to 3

So for every 7 books Ethan read, Sadie read 3 books.

Answer:

A) 30π mi²

Step-by-step explanation:

area of full circle = πr² = (3.14)(6²) = 113.04 mi²

area of 5π/3 segment = (113.04)(5π/3)/2π) = 94.2 mi² = 30π mi²

Answer:

a = 38 degree

b = 54 degree

c = 54 degree

Step-by-step explanation:

a = 180 - 142 = 38 ( angle on a straight line is equal to 180)

To determine the value of b, we have to find the other missing angle in the triangle.

the value of the missing angle is 38

Alternate angles are equal. the missing angle is alternate to angle b which has a value of 38

b = 180 - (38 + 88) = 54

c = 54

Answer:

its C
