Hello! answer: D. 180

Step-by-step explanation:

What you do for these is find the surface area for each face separately then add them up so...

for the sides its 18 for the top and bottom it's 48 for the front and back it's 24 so now we add all 6 up so... 18 + 18 + 48 + 48 + 24 + 24 = 180 Hope that helps!

Answer:

180 in²

Step-by-step explanation:

To wrap the given box, we need to find the total surface area of the figure.

TSA of cuboid = 2 (lb + bh + hl)

= 2 { (6*8) + (8*3) + (3*6) }

= 2 ( 48 + 24 + 18 )

= 2 * 90

= 180 in²

260 + 18% = 306.80

Total amount paid by Jamal is $305

Step-by-step explanation:

Given that;

Cost of meal = $250

Local sale tax rate = 4%

Percentage of tip left by Jamal = 18%

Find:

Total amount paid by Jamal

Computation:

Total tax paid by Jamal = 250 × 4%

Total tax paid by Jamal = $10

Total amount of tip left by Jamal = 250 × 18%

Total amount of tip left by Jamal = $45

Total amount paid by Jamal = Cost of meal + Total tax paid by Jamal + Total amount of tip left by Jamal

Total amount paid by Jamal = 10 + 45 + 250

Total amount paid by Jamal = $305

yes because 46 ounces is equal to 2.9 pounds

Answer: Yes

Step-by-step explanation:

Im correct because, 1 pound equals 16 ounces. So to find how much 2 pounds is we just have to multiply 16 by 2. 16 times 2 equals 32 ounces and 46 ounces is more then 32 ounces, so it is greater.

Answer:

28pi, 10pi

Step-by-step explanation:

So, lets go over a few things.

What is circumference?

Circumference is the permiteter of a circle.

The formula for it is 2*r*pi.

Now, lets go over what radius and diamater is.

Diamater is the distance between the two opposite sides of the circle.

The radius is half of the diamater, and is the distance between one side of the circle and the middle.

Problem #1:

The distance from the middle to the side of the circle is 14.

This will be the radius, not the diamater.

Lets plug this into the formula:

2*14*pi

=

28*pi

=

28pi

This is your answer.

Problem #2

The distance from the two opposite sides of the circle is 10.

So the radius will be half of this, being 5.

Now lets plug this in:

2*5*pi

=

10*pi

=

10pi

This is your answer.

Hope this helps!

Answer:

When x = 1, (f◦g)(x) is -2.

Step-by-step explanation:

Composite function:

The composite function of f and g is given by:

[tex](f \circ g)(x) = f(g(x))[/tex]

In this question:

[tex]f(x) = x - 3, g(x) = x^2[/tex]

Composite function:

The composite function is:

[tex]f(g(x)) = f(x^2) = x^2 - 3[/tex]

At x = 1

[tex](f \circ g)(1) = 1^2 - 3 = 1 - 3 = -2[/tex]

So

When x = 1, (f◦g)(x) is -2.

Answer:

1. 3/4 2. -1/3

Step-by-step explanation:

#1:

Given rise/run, the rise is 3, and the run, is 4, so... 3/4

#2:

Given rise/run, the rise is 2, and the run is 6, so... you get 2/6 = 1/3. However, don't forget that the slope is negative, so it'll be -1/3.

Answer:

3. 3/4

4. -1/3

Step-by-step explanation:

Since the rise and run formula is slope = (y1-y2)/(x1-x2),

3. (2 - (-1) ) / (2- (-2) ) = 3/4

4. (-1- (-3) ) / (-2 - (-4) ) = -2/6 = -1/3

Answer:

4 : 7

Step-by-step explanation:

First, you can start by moving all the terms to one side:

14x^2 + 6xy - 8y^2 = 0

Now we can start to factor this equation in order to find the ratio. We can start by factoring out the GCF, which is 2:

2(7x^2 + 3xy - 4y^2) = 0

In order to factor this equation we multiply the coefficients in front of the x^2 and y^2 term to get: 7 * -4 or -28. We are looking for numbers that have a product of -28 and a sum of 3(as the coefficient of the xy term). These two numbers are 7 and -4. We can rewrite the equation as:

2(7x^2 + 7xy - 4xy - 4y^2) = 0

Now, we can start to factor by grouping:

2( 7x[x + y] - 4y[x + y] ) = 0

And we can factor out [x + y]:

2(x + y)(7x - 4y) = 0

So, we can use the zero product property to get two equations:

x + y = 0

and

7x - 4y = 0

You get:

x =  -y

and

7x = 4y

We can get cancel out the first solution because both x and y have to be positive. Rearranging the second equation we can get x : y = 4 : 7

Answer:

Step-by-step explanation:

The original angle of 30° is in a linear pair on a straight angle with ∠1. So since straight angles equal 180 subtract 30 from 180 to find m∠1, which is 150°.

The original angle of 30° is a vertical angle with ∠3, the same goes for ∠1 and ∠2. So those angles will be congruent. ∠1 = 30° and ∠2 = 150°

Lastly use corresponding angles to find out the values of ∠4, ∠5, ∠6, ∠7.

∠4 is corresponding to 30° so ∠4 is 30°

∠5 is corresponding to ∠1 so ∠5 is 150°

∠6 is corresponding to ∠2 so ∠6 is 150°

∠7 is corresponding to ∠3 so ∠7 is 30°

Hope this helps :)
