Find the difference: 4/5 - 1/3

Answers

Answer 1

Answer:

7/15

A restaurant sells burritos for $8.00 each. To buy supplies, the restaurant pays $1.50 for the meat and $1.00 for the other ingredients in each burrito.

What is the profit the restaurant makes for selling 100 burritos? Does the restaurant make or lose money? Explain your reasoning.

Answers

Answer:

$250

Step-by-step explanation:

Add prices $1.50 for meat and $1.00 for the other ingredients

1.50 + 1.00=2.50

Then multiply that by 100 because it 100 burritos

100*2.50= 250

$250 would be the answer for it

pls help me

Answers

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

A = plane

B = whale

C = sunken ship

Step-by-step explanation:

The given vertical number line is modelling the positions of objects and animals in relation to sea level.

Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.

From inspection of the given number line:

Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.

We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.

We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.

A is plane b is whale c is sunken ship

A company is expanding its building area from 13,500 square feet to 17,010 square feet. What is the percentage increase of the area of the building space?
A.
2.6%
B.
74%
C.
35.1%
D.
26%

Answers

Answer:

I believe it's B but not so sure.

Answer:

The correct answer to your problem is D, 26%.

Step-by-step explanation:

Using the formula: difference/old, the percentage increase in the area of the building space can be evaluated.

By finding the difference in terms of 17,010 and 13,500, result is 3,510.

By finding the quotient of 3,510 (difference) and 13,500 (initial building area), the result is 0.26

The product of 0.26 and 100 (to get a percent) results in 26%

Therefore, D is the correct answer.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.

Answers

Answer:

The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.

Substituting the given values, we get:

V = (1/3) x 3.14 x 9^2 x 16

Calculating this expression gives us:

V = 1810.08 cubic inches

Rounding to the nearest hundredth gives us:

V ≈ 1810.08 cubic inches (rounded to two decimal places)

Therefore, the volume of the cone is approximately 1810.08 cubic inches.

Answer:

1363.04

Step-by-step explanation:

V = (1/3) * 3.14 * 9^2 * 16

Simplifying:

V ≈ 1363.04 cubic inches

The volume of the hexagonal prism is 1257.47units^3

The volume of the cylinder is 265.78

Explanation: Lets start with the hexagonal prism. The equation for a hexagonal prism is 3 times the square root of 3 divided by 2 (2.59807621135) multiplied by the base edge (a) multiplied by the height(h), so your equation would end up being set up like this

(3*(the square root of 3)/2)*a^2*h

Now insert your values,

a= 11
h= 4

After you calculate your answer you'll get 1257.47 cm^3


The equation for a cylinder is 3.14*r^2*h where 3.14 is pie, r is the radius, and h is the height. In the diagram we were given the diameter. We can get the radius by dividing the diameter by 2 (diameter/2 = radius) so we get these values

r= 3
h= 9.4

After putting that into your equation you'll find that the volume is 265.78

Answer:

265.78 cm (for the cylinder)

Step-by-step explanation:

Formula: πr²h ( pi times radius squared times height)

3.14 × 3² × 9.4= 3.14 × 9 × 9.4= 265.78 cm

Find an explicit formula for the geometric sequence 3, 15, 75, 375...

Answers

Answer:

3 * 5 ^ (n-1)

Step-by-step explanation:

3 is the first term and it multiplies by 5

The explicit formula for the geometric sequence is \(T_n = 3(5)^{n-1}\)

The standard explicit formula for  a geometric sequence is expressed as:

\(T_n = ar^{n-1}\\\)

a is the first term

r is the common ratio

n is the number of terms

Given the sequence of numbers 3, 15, 75, 375...

r = 15/3 = 75/15 = 5

a = 3

Substitute the given parameters into the formula to have:

\(T_n = ar^{n-1}\\T_n=3(5)^{n-1}\)

Hence the explicit formula for the geometric sequence is \(T_n = 3(5)^{n-1}\)
