Answer:

8) 10 15/16 ft³

9) 20 5/6 ft³

Step-by-step explanation:

Volume of a rectangular prism is

l * b * h,

Question 8

We're given the area

Area = l * b

So we substitute the area for length and breadth.

Volume = Area * height

Volume = 4 3/8 * 2 1/2

Volume = 35/8 * 5/2

Volume = 175/16

Volume = 10 15/16 ft³

Question 9

Volume = 5 * 1 2/3 * 2 1/2

Volume = 5 * 5/3 * 5/2

Volume = 5 * 25/6

Volume = 125/6

Volume = 20 5/6 ft³

Answer:

-1.5 L/h

Step-by-step explanation:

The volume of water in a reservoir decreased from 24.000L to 18.000L between 06.00 and 10.00.

We need to find the average rate of decrease in volume of water. It can be solved as follows :

[tex]Rate=\dfrac{18-24}{10-6}\\\\=-1.5\ L/h[/tex]

The negative sign shows the decrease in volume. Hence, the rate of decrease in volume of water is 1.5 L/h.

Answer:

100 is going to be the denominator or whole.

Step-by-step explanation:

A percent is basically equally to a number x/100

Answer:

1 < x < 12

Step-by-step explanation:

The triangles satisfy the Converse Hi nge Theorem Condition the two triangles have two corresponding equal sides. Thus, the included angle of the triangle that has the largest length of the third side is greater than the included angle of the other triangle with a lesser third side length.

Thus,

33 > 3x - 3

Solve for x

33 + 3 > 3x - 3 + 3

36 > 3x

36/3 > 3x/3

12 > x

To ensure the angle is not 0 or negative, thus:

3x - 3 > 0

Solve for x

3x - 3 + 3 > 0 + 3

3x > 3

3x/3 > 3/3

x > 1

Possible range of values of x would be:

1 < x < 12

Answer:

b^-6

Step-by-step explanation:

(b^-2) / (b^4) = b^(-2 - 4)

Answer:

Step-by-step explanation:

140

Answer:

19° = m∠B

73° = m∠T

88° = m∠R

Step-by-step explanation:

Let x = measure of angle B

then 4x - 3 = measure of angle T

 and 31 + 3x = measure of angle R

x + 4x - 3 + 31 + 3x = 180

8x + 28 = 180

8x = 152

x = 19° = m∠B

4(19) - 3 = 73° = m∠T

31 + 3(19) = 88° = m∠R

Explanation:

Multiply the fractions 9/10 and 2/5 to get

(9/10)*(2/5)

(9*2)/(10*5)

18/50

9/25

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

Here's a visual way to see what's going on. Start by drawing a rectangle of any size or shape. Cut the rectangle vertically into 10 equal slices. Then shade 9 of those slices to represent the fraction 9/10, which is how far (in miles) Lewis walked. See the diagram below. Specifically, refer to figure 1.

The friend walked 2/5 of this shaded amount. Draw 4 horizontal lines to split each vertical bar into 5 equal pieces. So we'll be forming a grid of smaller rectangles. For any given column, you'll shade exactly 2 smaller rectangles out of the 5 total. Hence the 2/5. This is shown in yellow in figure 2. The yellow region is 2 units tall by 9 units across, so we have 2*9 = 18 yellow rectangles in all. This is out of 5*10 = 50 smaller rectangles overall.

That's how we get to the fraction 18/50 which reduces to 9/25 when you divide both parts by the GCF 2.

Answer:

A

Step-by-step explanation:

This is the same as ((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2))*((2^3)/(4^2)) which is equal to (2^(3+3+3+3+3)/4^(2+2+2+2+2)), so its (2^15/4^10)

Answer:

80.5π cm

Step-by-step explanation:

We want to find the area where the label should go onto the can. If we were to take the label and flatten it onto a 2D surface, we would multiply 11.5 cm by the width, which is equivalent to the circumference of the circle. The circumference of the circle can be calculated using the equation 2πr. The radius is 3.5 cm, so the circumference of the circle is 7π. We multiply 7π by 11.5 to get 80.5π cm.

Step-by-step explanation:

The normalcdf means the normal cumulative density function, it can be accessed from the TI Calculators from the DIST section which also includes the normalcdf, invNorm, tpdf and other distribution functions.

The syntax is as follows :

normalcdf (lower bound, upper bound, mean, standard deviation)

Hence, to Obtian the probability that a value is between a and b, with mean, x and standard deviation, s

The normalcdf is written as normalcdf(a, b, x, s)

Answer:

[tex](x - 5)^2 + (y - (-3))^2 = 16[/tex]

Answer:

(x - 5)² + (y + 3)² = 16

Step-by-step explanation:

(x - h)² + (y - k)² = r²

(h, k) is the center = (5, -3)

r is the radius = 4

r² = 4² = 16

The experimental and theoretical probabilities for the given experiment are:

i) The experimental probability of rolling a 2 is equal to the quotient between the number of times that the outcome was a 2 and the total number of times that the number cube was rolled, so the probability is:

P = 8/50 = 0.16

ii) The theoretical probability assumes that all the numbers (6) have the same probability of rolling up.

Then all the numbers have a probability of 1/6.

This means that the theoretical probability of rolling a 2 is:

P(2) = 1/6 = 0.167

iii) The experimental probability of NOT rolling a 2 is computed in a similar way than the first one, if out of 50 rolls, in 8 we rolled a 2, then in 42 we did not rolled a 2.

So the probability is:

P = 42/50 = 0.84

iv) The theoretical probability of not rolling a 2 is equal to 1 minus the theoretical probability of rolling a 2.

P = 1 - 1/6 = 5/6 = 0.833...

v) For the experimental probability of getting a 1, we see that out of 50 rolls, in 10 we rolled a 1, so the probability is:

P = 10/50 = 1/5 = 0.2

Answer:

Step-by-step explanation:

value is decreasing so rate should be <1

f(x)=Pr^x

=1250 (0.8)^x

if x=1

f(1)=1250(0.8)^1=1000 $

if x=2

f(2)=1250(0.8)^2=800 $

if x=3

f(3)=1250(0.8)^3=640  $

so D is the correct answer.

Answer:

y-9=4/5(x+7)

Step-by-step explanation:

Point slope for is y-y1=m(x-x1). In this case, y1 is 9, x1 is -7, and m is 4/5. Therefore, we can fill in this equation. The equation will be y-9=4/5(x--7) This is equal to y-9=4/5(x+7).
