A picture measuring 2.5" high by 6" wide is to be enlarged so that the width is now 18 inches. How tall will the picture be?

Answers

Answer 1

7.5
2.5 to 6 so if 6 is raised to 18 thats times 3 so just times 2.5 by 3 and you would 7.5

Answer 2

Let t = height of picture

2.5" long/6" wide = t/18 " wide

6t = 18*2.5

6t = 45

t = 45/6

t = 7.5 inches

The area of rectangle A is 11/12 square meters.The area of rectangle B is 8/12 square meters.How much larger is rectangle A?

Answers

Answer:
Rectangle A is 1/4 m² larger than rectangle B

Explanation:
We are given that:
Area of triangle A = 11/12 m²
Area of rectangle B = 8/12 m²

To know how much larger is rectangle A than rectangle B, all we have to do is subtract the area of rectangle B from rectangle A as follows:
Difference in area = 11/12 - 8/12 = 3/12 = 1/4 m²

This means that rectangle A is 1/4 m² larger than rectangle B.

Definition of classic probability

Answers

Classical probability is the statistical concept that measures the likelihood of something happening, but in aclassic sense, it also means that every statistical experiment will contain elements that are equally likely to happen.

Final answer:

Probability is the likelihood, or chance, that a certain event will occur. The easiest way to understand probability is with coin tosses. Probability can also be applied in various fields such as medicine and stock market.

Explanation:

Probability is the likelihood, or chance, that a certain event will occur. The easiest way to understand probability is with coin tosses.

When you toss a coin, the chance of a head turning up is 50 percent. This is because a coin has only two sides, so there is an equal chance of a head or tail turning up on any given toss.

Probability can also be applied in various fields. For example, doctors use probability to determine the chance of a vaccination causing the disease the vaccination is supposed to prevent.

Stockbrokers use probability to determine the rate of return on a client's investments. In statistics, we study populations and use a sample to gain information about the larger population. Data are the result of sampling from a population.

~Nonportrit

The expression equal to 5p is Option A: p + p + p + p + p. Other options do not correctly represent the sum of five instances of p.

The correct expression that is equal to 5p is A. p + p + p + p + p. Let's break it down:

A. p + p + p + p + p adds the variable p five times, which by definition equals 5p.

B. 4p + 1 simplifies to 4p + 1, which is not equal to 5p because it includes an additional constant term.

C. p + 5 represents the variable p plus the number 5, which is not the same as multiplying p by 5.

D. p3 + p2 is a polynomial with different powers of p and does not simplify to 5p.

Therefore, option A is the correct answer.

Which expression is equal to 5p?

A. p + p + p + p + p

B. 4p + 1

C. p + 5

D. p3 + p2

3 + d < 3 – d. Solve

Answers

For the sake of solving, temporarily replace the < sign with an = sign. Solve as you normally would.
3 + d = 3 - d
add d to both sides
3 + 2d = 3
Subtract 3 from both sides
2d = 0
Now replace the = sign with the < sign again.
2d < 0
Divide both sides by 2 to get your final answer.
d < 0
If you are ever uncertain with an answer to an inequality, the best thing to do is plug in a random number! (In this case, make sure the number is less than 0)
3 + (-1) < 3 - (-1)
3 - 1 < 3 + 1
2 < 4
(-1) is less than zero, and when plugged into the inequality the values of the left side is less than the value of the right side. This shows that d IS < 0.

how to solve this cause I was gone for 1/2 of my class and missed stuff.

Answers

the answer is 58°

a triangle can only have 180 degrees

we already know the measure of two angles

28+30= 58

because the third angle (let's call it x) for a a straight line (180°) with y, we know that
x + y =180

180-58 = 122°
x = 122°
180 - 122 = 58
y = 58°

The interior angles of all triangles add to equal 180 degrees (triangle angle sum theorem)Supplementary angles add to equal 180 degrees

To find y, first find the measure of the third interior angle. We'll call it x.

The triangle angle sum theorem allows us to create an equation to find x. Set the interior angle values equal to 180 and solve.

180 = 28 + 30 + x

Add the constants.

180 = 58 + x

Subtract 58 from both sides.

122 = x

Now, ∠x (which we now know measures 122°) is supplementary to ∠y. Set them equal to 180 and solve for y.

180 = 122 + y

Subtract 122 from both sides.

58 = y

Answer:

m∠y = 58°

Answer:

This was the correct answer, I even provided proof from my own test. Hope this helps!

Step-by-step explanation:

A hair company makes three batches of scented shampoo using the recipe shown. Each batch contains a different total amount of shampoo. 1/2 is pineapple, 1/5 is banana, 3/10 is coconut.
Batch 1:
Pineapple
Banana
Coconut is 2 1/10

Batch 2:
Pineapple
Banana is 3 1/5
Coconut

Batch 3:
Pineapple is 2 1/2
Banana
Coconut

Answers

Answer:

Batch 1: Pineapple = 3 1/2; Banana = 1 2/5

Batch 2: Pineapple = 8; Coconut = 4 4/5

Batch 3: Banana = 1; Coconut = 1 1/2

Step-by-step explanation:

For Batch 1:

We know that coconut is 3/10 of the mixture, and we have 2 1/10 coconut:

3/10x = 2 1/10

Converting 2 1/10 to an improper fraction, we have

3/10x = 21/10

Divide both sides by 3/10:

3/10x ÷ 3/10 = 21/10 ÷ 3/10

To divide fractions, flip the second one and multiply:

x = 21/10 × 10/3 = 210/30 = 7

This means we have 7 total of the mixture.

1/2 of this is pineapple: 1/2(7) = 7/2 = 3 1/2

1/5 is banana: 1/5(7) = 7/5 = 1 2/5

For Batch 2:

1/5 of the total is banana; we have 3 1/5 banana:

1/5x = 3 1/5

Convert the second fraction to an improper fraction:

1/5x = 16/5

Divide both sides by 1/5:

1/5x÷1/5 = 16/5÷1/5

Flip the second fraction and multiply:

x = 16/5×5/1 = 80/5 = 16

We have 16 of the total shampoo.

Pineapple is 1/2 of this:

1/2(16) = 8

Coconut is 3/10 of the total:

3/10(16) = 48/10 = 4 8/10 = 4 4/5

For Batch 3:

Pineapple is 1/2 of the total. We have 2 1/2 pineapple:

1/2x = 2 1/2

Convert the fraction on the right to improper:

1/2x = 5/2

Divide both sides by 1/2:

1/2x÷1/2 = 5/2÷1/2

Flip the second fraction and multiply:

x = 5/2×2/1 = 10/2 = 5

We have 5 total shampoo.

Banana is 1/5 of this:

1/5(5) = 1

Coconut is 3/10 of this:

3/10(5) = 15/10 = 1 5/10 = 1 1/2

Kevin has 23 dimes and quarters in his piggy bank. If the value of these coins is $4.55, how many dimes and quarters does he have? Set up and solve a system of equations to solve the problem

Answers

Final answer:

To solve the coin problem, two equations are set up, one for the total number of coins and another for the total value in dollars. By using the elimination method, we find that Kevin has 8 dimes and 15 quarters in his piggy bank.

Explanation:

To solve this problem, we assign variables to represent the number of each coin type: let 'd' be the number of dimes, and 'q' be the number of quarters.

Now, we can set up our two equations. The first equation represents the total number of coins:

d + q = 23.

The second equation derives from the total value of the coins:

0.10d + 0.25q = 4.55.

Multiplying the second equation by 100 to clear the decimals gives us;

10d + 25q = 455.

To solve the system, we can use either substitution or elimination. Here, we will use elimination.

If we multiply the first equation by 10 (giving 10d + 10q = 230), we can subtract it from the modified second equation to eliminate 'd':

(10d + 25q) - (10d + 10q) = 455 - 230, simplifying to 15q = 225.

Dividing both sides by 15 gives us q = 15, which indicates Kevin has 15 quarters.

Substituting 'q = 15' into the first equation gives us d + 15 = 23, which simplifies to d = 8.

Therefore, Kevin has 8 dimes and 15 quarters.

a line with a slope of 1/8 passes through the points (u, -9) and (6, -8). what is the value of u?

Answers

Answer:
u = -2

Explanation:
Slope of the line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)

We are given :
slope = 1/8
point (u,-9) represent (x1,y1)
point (6,-8) represent (x2,y2)

Substitute with the givens in the above equation and solve for u as follows:
slope = (y2-y1) / (x2-x1)
1/8 = (-8--9) / (6-u)
1/8 = (1) / (6-u)
1* (6-u) = 1*8
6-u = 8
u = 6-8
u = -2

Explanation:

To solve the equation 8n + 2 - 6n = 9 + 2n - 13, we need to simplify both sides and combine like terms.
Starting with the left side of the equation, 8n - 6n can be simplified to 2n. And on the right side, 9 - 13 is -4.
So, we have 2n + 2 = -4. We can now subtract 2 from both sides to isolate the variable n. This gives us 2n = -6. To solve for n, divide both sides of the equation by 2: n = -3.

Therefore, the equation 8n + 2 - 6n = 9 + 2n - 13 has only one solution, n = -3.
