Answer:

112 inches I believe! I hope this helps!

Step-by-step explanation:

Answer:

2004 cubic inches

Step-by-step explanation:

Looking at the figure, there seems to be a chunk missing from the front. Since the overall length is 15 inches, and the length near the missing chunk is 12, then the missing length is 3. If that chunk was filled in, this would have been a 17 * 15 * 8 rectangluar prism. That would have been 2040 cubic inches. (120 * 17) However, a 3 by 8 by 3 triangular prism is missing.

1/2(3 * 8 * 3)

1/2(24 * 3)

1/2(72)

36

Now, subtract 36 from 2040.

2040 - 36

2004 cubic inches

2004 cubic inches of gas will fill this gas can.

90

Step-by-step explanation:

Order of operations is: PEMDAS = parentheses, exponents, multiplication, division, addition, subtraction

1. 56 + 9 x 2

first we multiply:

= 56 + 18

then we add:

=74

-----------------------

2. 100 / 5 x 4

first we multiply:

= 100 / 20

then we divide 100 by 20:

= 5

-----------------------

3. 8 x 12 - 6

first we multiply:

= 96 - 6

then we subtract:

Step-by-step explanation:

Answer:

length = 6 cm

width = 1 cm

Step-by-step explanation:

l = length

w = width

l = 4 + 2w

2(4 + 2w) + 2w = 14

8 + 4w + 2w = 14

8 + 6w = 14

6w = 6

w = 1

find length:

l = 4 + 2(1)

l = 6

Answer:

$767 per month for the next 4 years

Step-by-step explanation

first it’s minus the 2800 they gave him and that’s 9,200 then divided by the amount of months in a year which is 12 you end up with 766.6 but rounded that would be the closest answer and then when you multiply 767x12 it’s 9200 plus the 2800 it’s 12,000 which means it checks out.

Answer: W

Step-by-step explanation:

i took the test

If we have a y intercept of -8, that means that the point falls on the y-axis, therefore x = 0. So, we have a point (0, -8) and we have a slope m = 23.

y = mx + b

y = 23x + b

Now, we can plug in the point values x = 0, y = -8

-8 = 0 + b

b = -8

If we plug b back into our original formula, we get:

y = 23x - 8

Answer: pretty sure it’s $56.25

Step-by-step explanation:

4200-1500= 2700 divided by 48 months (4 years).

Answer:

44

Step-by-step explanation:

Since a triangle has a total of 180 degrees, 62+44=136

180-136=44

Answer:

f (x) = x + 2

We evaluate the value of x = -4

f (-4) = (-4) + 2

f (-4) = -2

f (x) = -2x + 4

We evaluate the value of x = 4

f (4) = -2 (4) +4

f (4) = -8 + 4

f (4) = -4

f (x) = 3x -4

We evaluate the value of x = 0

f (0) = 3 (0) -4

f (0) = 0-4

f (0) = -4

The value of the function at x = 1 is, f(x) = - x - 4 which equals f(1) = - 3.

We know the absolute value function of the modulus function always outputs a positive value irrespective of the sign of the input.

In piecewise terms  | x | = x for x ≥ 0 and | x | = - x for x < 0.

Similarly, A piecewise function can also be in terms of without modulus.

Given, f(x) = - x - 4 for x < 3.

f(x) = x² - 7, for 3 ≤x < 12.

f(x) = (120/x) + 5, for x ≥ 12.

Now, At x = 1, It satisfies,

f(x) = - x - 4 for x < 3.

Therefore, f(1) = - (-1) - 4.

f(1) = - 3.

Answer:

Pat is right

Step-by-step explanation:

first multiply/divide then add/subtract,

Beth: 20 - 15 = 45 => 5 ≠ 45

Pat: 20 - 15 = 5 => 5 = 5

Answer:

Pat

Step-by-step explanation:

There is only one correct answer. To find it, you must follow the correct order of operations.

There is a subtraction and a multiplication. There are no parentheses.

The rule is that you must do the multiplication before the subtraction.

20 - 5 * 3 =

= 20 - 15

= 5

In order to get Beth's answer, you'd have to do the subtraction first. If there were parentheses like this: (20 - 5) * 3, then you'd do the subtraction first getting 15 * 3 which is 45, but the problem has no parentheses, so the correct answer is 5.

The correct answer is 5, and Pat is correct.

Answer:

sin I = 0.244

Step-by-step explanation:

Given that,

Perpendicular, P = 195

Hypotenuse, H = 796

We need to find the value of [tex]\sin(I)[/tex]. We know that,

[tex]\sin\theta=\dfrac{P}{H}[/tex]

Substitute all the values,

[tex]\sin I=\dfrac{195}{796}\\\\\sin(I)=0.244[/tex]

So, the value of sin(I) is equal to 0.244.

Answer:

a) 16 meters ; b) 8 seconds

Step-by-step explanation:

The function can be represent with a parabola whose vertex is its maximum point

for answer the first question we have to find the y of the vertex

first of all we have to find the x

Vertex (x) = -b/2a = -8/-2 = 4

if we substitute t with 4, we can find the y

Vertex (y) = -(4^2) + (8*4) =

= -16 + 32 = 16

so the answer is 16 meters

for answer the second question we have to find where the parabola intercepts the x axis, that means solve the associated equation:

-t^2 + 8t = 0

t^2-8t = 0

t(t-8) = 0

t = 0

t = 8

the parabola intercept the x axis in (0,0) and in (8,0)

if we find the distance between this two points we can answer to the question

8-0 = 8 seconds

Answer:

54.9 meters

Step-by-step explanation:

Given: Avery threw football 60 yards

To find: How high it is in meters

Solution: Simply convert 60 yards to meters, by doing that, find out how many meters are in one yard

                                                   1 = 0.9144

Multiply the result by 60

                                              60 × 0.9144 =  54.86

Then, round it to the nearest tenths;  54.9                                              

Avery threw the football 54.9 meters high

Answer:

No solution

Step-by-step explanation:

The quadratic formula is

[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$.[/tex]

where a is the coefficient of x squared, b is the coefficient of x, and c is a regular number.

Here, we have

a = 1

b = 7

c = 16

Plugging in values, we have

[tex]\frac{-7 +\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]

and

[tex]\frac{-7 -\sqrt{49 - 4(1)(16)}}{2(1)}[/tex]

The first equation solves to an i term, so there is no way that there is an answer.

The second equation is also an i term, meaning there are no solutions to this equation
