Final answer:

The areas of the parallelograms are calculated by multiplying the base by the height. The first parallelogram's area is 32 m², and the second parallelogram's area is 140 in².

Explanation:

Natalia is calculating the areas of parallelograms using the formula Area = base × height. For the first parallelogram with a base (b) of 8 meters and a height (h) of 4 meters, the area will be:

Area = base × height = 8 m × 4 m = 32 m².

For the second parallelogram given by her friend, with a base (b) of 14 inches and a height (h) of 10 inches, the area will be:

Area = base × height = 14 in. × 10 in. = 140 in².

This formula is essential for understanding the relation between the dimensions of a parallelogram and its surface area.

Answer:

A = 36 pi in^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

A = pi (6)^2

A = 36 pi in^2

Answer:

36pi in²

Step-by-step explanation:

Area = pi × r²

= pi × 6²

= 36pi

Answer:

3.07% probability that the​ newspaper's sample will lead it to predict​ defeat

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

For a proportion p with n voters, we use [tex]\mu = p, \sigma = \sqrt{\frac{p(1-p)}{n}}}[/tex]

In this problem, we have that:

[tex]p = 0.55, n = 354[/tex]

So

[tex]\mu = 0.55, \sigma = \sqrt{\frac{0.55*0.45}{345}}} = 0.0268[/tex]

What is the probability that the​ newspaper's sample will lead it to predict​ defeat?

That is, a percentage of 50% or less, which is the pvalue of Z when X = 0.5. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0.5 - 0.55}{0.0268}[/tex]

[tex]Z = -1.87[/tex]

[tex]Z = -1.87[/tex] has a pvalue of 0.0307.

3.07% probability that the​ newspaper's sample will lead it to predict​ defeat

Therefore, Tylers height is 144.78 centimeters.

Best of Luck!

The toy's height after 0-4 seconds can be found by substituting different values of t into the given equation.

The equation given to model the toy's height is h = -2t^2 + 7t + 4, where h is the height in feet and t is the time in seconds. To find the height of the toy after 0-4 seconds, we substitute different values of t into the equation.

For t = 0, h = -2(0)^2 + 7(0) + 4 = 4 feet.

For t = 1, h = -2(1)^2 + 7(1) + 4 = 9 feet.

For t = 2, h = -2(2)^2 + 7(2) + 4 = 12 feet.

For t = 3, h = -2(3)^2 + 7(3) + 4 = 11 feet.

For t = 4, h = -2(4)^2 + 7(4) + 4 = 4 feet.

Student council's savings reduced by [tex]\$56[/tex]

Step-by-step explanation:

Given:

Volunteers buy 8 backpacks for $4 each and fill each backpack with paper and pens that cost $3

To find:

Change in student council's savings

Solution:

Cost of paper and pens in each backpack = [tex]\$3[/tex]

Total cost of paper and pens in 8 backpacks = [tex]\$8[/tex]× [tex]\$3[/tex] =[tex]\$24[/tex]

Cost of each backpack = [tex]\$4[/tex]

Total cost of 8 backpacks = [tex]8[/tex]×[tex]\$4[/tex] = [tex]\$32[/tex]

So,  student council's savings reduced by [tex]\$32+\$24=\$56[/tex]

Step-by-step explanation:

The sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

5 m, 7 m, and 11 m do not form a right triangle.

A triangle is said to be right-angled if one of its angles is exactly 90 degrees. The total of the other two angles is 90 degrees. Perpendicular and the triangle's base are the sides that make up the right angle. The longest of the three sides, the third side is known as the hypotenuse.

To determine whether 5 m, 7 m, and 11 m form a right triangle, we need to use the Pythagorean theorem.

The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. That is:

c² = a² + b²

Where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

So, let's check if the Pythagorean theorem holds true for the lengths of 5 m, 7 m, and 11 m:

11² = 5² + 7²

121 = 25 + 49

121 = 74

This is not true, so 5 m, 7 m, and 11 m do not form a right triangle.

Answer:

7/25

Step-by-step explanation:

Probability is the likelihood or chance that an event will occur.

Probability = expected outcome/total outcome

If the box contains 3 black pens, 7 blue pens, and 5 red pens, the total number of pens in the box is 3+7+5 = 15pens

Probability of pulling a red pen and replacing = 5/15 = 1/3

Probability of pulling a blue pen and replacing = 7/15

Probability of pulling a black pen and not replacing(using it) = 3/15

{Note that the total number of outcome used will still be 15 since the black pen was pulled out last even though it wasn't replaced.}

P(red, then blue, then black) = 1/3×7/15×3/15

= 63/225

= 7/25

Answer:

No

Step-by-step explanation:

First, convert all dimensions to be uniform.

1ft=0.08333 ft

90ft=90*0.0833=7.5ft

40 ft=40*0.0833=3.33 ft

The diagonal of the vehicle will be

[tex]\sqrt 7.5^{2}+3.33^{2}=8.20738150149675\ approx 8.2 ft[/tex]

Since the diagonal of vehicle is smaller than 12 ft, the pipe can't fit unless divided into two equal parts.

Final answer:

The 12-foot pipe can fit inside the van due to its dimensions.

Explanation:

The pipe is 12 feet long, which is equivalent to 144 inches. The interior dimensions of the van are 90 inches in length, which is shorter than the length of the pipe,

40 inches in width, and 40 inches in height, providing enough width and height for the pipe to fit. Therefore, the pipe will fit inside the plumber's van comfortably.

When 5 is subtracted from the square of a number can be represented as follows;

The result is 4 times the number. The remaining part of the equation can be represented as follows:

Lets find the negative solution below

x²- 5 - 4x = 0

x² - 4x - 5 = 0

x² + x - 5x - 5 = 0

x(x + 1) -5(x + 1)

(x-5)(x + 1)

x = 5 or -1

By solving the quadratic equation x^2 - 5 = 4x, we get two solutions: x = 5 and x = -1. The negative solution to this equation is x = -1.

Let's denote the unknown number as x. The problem statement translates to the equation x2 - 5 = 4x. To find the negative solution, we must solve this quadratic equation.

First, we move all terms to one side to get x2 - 4x - 5 = 0.

We then factor this quadratic if possible or use the quadratic formula. In this case,

(x - 5)(x + 1) = 0.

Setting each factor equal to zero gives us the solutions x = 5 and x = -1.

The question asks for the negative solution, so x = -1.

Step-by-step explanation:

2x - 3(x + 6) = -3(x - 2)

Distribute

2x -3x -18 = -3x +6

Combine like terms

-x -18 = -3x+6

Add 3x from each side

-x+3x -18 = -3x+3x +6

2x -18 = 6

Add 18 to each side

2x-18+18 = 6+18

2x = 24

Divide each side by 2

2x/2 = 24/2

x = 12

Answer:

[tex]x = 12[/tex]

Step-by-step explanation:

[tex]2x - 3(x + 6) = - 3(x - 2) \\ 2x - 3x - 18 = - 3x + 6 \\ 2x - 3x + 3x = 18 + 6 \\ 2x = 24 \\ \\ x = \frac{24}{2} \\ \\ x = 12[/tex]

Answer:ABCD

Step-by-step explanation:

Alternate interior angles are congruent if two lines are parallel, leading to the similarity of triangles through the Angle Angle Angle theorem.

Alternate interior angles are congruent only if the two other lines are parallel. If the two other lines are not parallel, the angles will still be alternate interior angles but they will not have the same measure, that is, they will not be congruent. Two triangles are similar if all three corresponding angles are congruent, established by the Angle Angle Angle (AAA) theorem.

Answer:

All corresponding sides and angles will be congruent

Balls: 6,12,18

Step-by-step explanation:

The completed ratio table is:

Dolls     4      4      12

Balls     6      12      6

Equivalent ratios: Dolls 1:3, Balls 1:2.

To find the missing values in the ratio table, we can set up proportions using the given ratios:

For Dolls:

4 dolls correspond to 12 dolls, so the missing value can be found using the proportion:

[tex]\(\frac{4}{12} = \frac{x}{12}\)[/tex]

[tex]\(x = \frac{4 \times 12}{12}\)[/tex]

x = 4

For Balls:

6 balls correspond to 12 balls, so the missing value can be found using the proportion:

[tex]\(\frac{6}{12} = \frac{y}{12}\)[/tex]

[tex]\(y = \frac{6 \times 12}{12}\)[/tex]

y = 6

The completed ratio table is:

Dolls     4      4      12

Balls     6      12      6
