Find the surface area of the cylinder.
9 cm
19 cm​

Answer:

192 in³

Step-by-step explanation:

A trapezoidal prism is a three dimensional solid that has two similar trapezoids at its top and base.The two similar trapezoids are connected by four rectangles connecting the corresponding sides of the two bases.

The Area of the trapezoid at the top or base = 1/2 (a + b)h

Where a and b are the lengths =  7 inches and 5 inches and the height (h) = 4 inches.

Therefore Area of the trapezoid at the top or base = 1/2 (a + b)h = 1/2(7 + 5)4 = 24 in²

The volume of gift box = Area of the trapezoid at the top or base × height of gift box = 24 × 8 = 192 in³

Answer:

x = -67

Step-by-step explanation:

Answer:

x^2 - 10x + 25

Step-by-step explanation:

I'm hoping that the 2 means squared.

x^2 - 10x + 25

Answer:

x^2 -10x+25

Step-by-step explanation:

(x-5)^2

(x-5)(x-5)

FOIL

first = x*x = x^2

outer:-5x

inner: -5x

last: -5*-5 = 25

Add them together

x^2 -5x-5x+25

Combine like terms

x^2 -10x+25

Standard form is ax^2 +bx +c so this is standard form

Answer:

It should be red or green 125 times

Step-by-step explanation:

The first thing to do here is to calculate the probability of selecting a red or a green marble

Total number of marbles = 7 + 3 + 2 + 8 = 20

Probability of selecting a red marble is 7/20

Probability of selecting a green marble is 3/20

The probability of selecting a red or a green marble = Probability of selecting a red marble + Probability of selecting a green marble = 7/20 + 3/20 = 10/20 = 1/2

Now our selection spans 250 times, the number of times it should have been a green or a red marble = The probability of selecting a green or a red marble * number of selection times = 1/2 * 250 = 125 times

Answer: 42/11 = 21/5.5

Step-by-step explanation:

1) Since the hypotenuse is 42 for one of the triangles it must be similar to the other triangles hypotenuse, 11.

2) Therefore, the ratio is 42/11.

3)The adjacent sides to the right angle are 21 and 5.5.

4)Therefore, the ratio is 21/5.5

The best estimate for my answer is 410 to the nearest ten

Answer: 88 square inches

If we want to wrap the box, we need to work out its surface area - the area that will need to be covered by the giftwrap.

This box is a cuboid, so there will be six faces, with only three different areas (each face has an identical pair).

Let's say the height is 2 in, the length is 6 in and the depth 4 in.

height = 2

length = 6

depth = 4

Let's find the area of the faces that measure height x length:

2 x 6 = 12 square in

Now let's do the same thing for height x depth:

2 x 4 = 8 square in

And finally for length x depth:

6 x 4 = 24

There are two of each of these faces, so let's multiply each result by two.

12 x 2 = 24

8 x 2 = 16

24 x 2 = 48

Finally, all that's left to do is add these numbers together to find the total surface area of the cuboid.

24 + 16 + 48 = 

88 square inches

Step-by-step explanation:

837 are females as 52.5 percent of 1800 equals 837.

Answer:

Females = 100 - percent of males = 100 - 53.5 = 46.5%

Number of females = 46.5/100 × 1800 = 837

Answer:

A.

Step-by-step explanation:

in A. your q is 3 so: a1=1 a2= a1*q=3 a3=a2*q=9 and so on.

i C. its almost the right answer too,but notice that a1 is 0. so 0*2 is still 0 so though it looks almost perfect the first number ruins it

Answer:

1) a30=96

2) 30(-20+96)/2

3) 1140

Step-by-step explanation:

I just did on Edg 2020

The solution is, the 30th term of the sequence a_30 = 96.

An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.

For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2.

The nth term of AP : a_n = a + (n – 1) × d

here, we have,

the given sequence is,

-20,-16, -12,-8,-4, ...

so, here, we have,

a = -20

d = 4

so, the 30th term of the sequence is,

a_30 = a + (30-1) d

         = -20 + 29*4

         = 96

Hence, The solution is, the 30th term of the sequence a_30 = 96.

Step-by-step explanation:

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. Since q may be equal to 1, every integer is a rational number.

Answer:

A rational number can be written as the ratio of two integers.

Step-by-step explanation:

Fractions (1/2), whole numbers (7 7/1), terminating decimals (2.33) repeating decimals (.222 repeating) square root of a perfect square (V-25 = 5/1) Integers (1 -2)

Answer:

See Explanation

Step-by-step explanation:

The text of the question is incomplete. However, the likely question that can be asked may imply that; "what number of corn package did she use?"

Given that

1 package of corn = 8 cups

1 serving = 1 cup

Total individual = 11

Servings per individual = 2

If there are 2 servings per individual then 1 package of corn will serve the following number of people.

1 package of corn = 8 / 2 individuals

1 package of corn = 4 individuals

Divide both sides by 4.

1 package of corn / 4 = 4 individuals / 4

¼ package of corn = 1 individual.

Re-arrange

1 individual = ¼ package of corn.

So, this means that 11 individuals will get;

[Multiply both sides by 11]

11 * 1 individual = ¼ * 11 package of corn

11 individuals = 11/4 package of corn

11 individuals = 2.75 packages of corn.

Hence, Ron will need 2.75 packages of corn for 11 individuals

Answer: C) H0 : μ = 250 , Ha: μ < 250

Step-by-step explanation:

The questions is incomplete. The correct question is

A restaurant advertises that its burritos weigh 250 g. A consumer advocacy group doubts this claim, and they obtain a random sample of these burritos to test if the mean weight is significantly lower than 250 g. Let u be the mean weight of the burritos at this restaurant and ĉ be the mean weight of the burritos in the sample. Which of the following is an appropriate set of hypotheses for their significance test? Choose 1 answer:

A) H0 : x = 250 , Ha : x < 250

B) H0 : x = 250 , Ha : x > 250

C) H0 : μ = 250 , Ha: μ < 250

C) H0 : μ = 250 , Ha: μ > 250

Solution:

The null hypothesis is the hypothesis that is assumed to be true. The restaurant advertises that its burritos weigh 250. This is the null hypothesis. 250 is the population mean,μ . Thus, the null hypothesis is

H0 : μ = 250

The alternative hypothesis is what the researcher expects or predicts. The consumer advocacy group tests if the mean weight is significantly lower than 250g. This is the alternative hypothesis. It is expressed as

H0 : μ < 250

Answer:

The Equation that represents these inverse variation is:

Speed is inversely proportional to Time

Speed (S) ∝ 1/ Time(T)

And the constant of proportionality = Distance(D)

Therefore, Speed = Distance/ Time

Step-by-step explanation:

For an inverse variation, one element increases while the other element decreases. In this question, the element or variable that increases is the speed while the element or variable that decreases is the time.

We can see from the question that

a) If he runs at an average speed of 15 feet/second, he can finish the race in 6 seconds.

b) If he runs at an average speed of 18 feet/second, he can finish the race in 5 seconds

Speed is inversely proportional to Time because the higher the speed, the lesser the time it takes to go or move in a particular direction or to go in a particular distance.

Hence, the Equation that represents these inverse variation is:

Speed is inversely proportional to Time

Speed (S) ∝ 1/ Time(T)

For inverse variation or proportionality, a constant is always needed

And the constant of variation or proportionality = Distance(D)

Therefore, Speed = Distance/ Time
