d. false

Answer 2

Answer:

a. False

b. True

c. True

d. False

Step-by-step explanation:

A

The formula for the area of a trapezoid treats the distance between the parallel sides as the height. Doing this lists the height as 4m.

B

You can separate a trapezoid into a rectangle with a width of 3 and a height of 4, as well as a right triangle with a width of 2 and a height of 4.

C

This expression is the written out portion of separating the trapezoid into a triangle and rectangle.

(3 * 4) represents the rectangle and (1/2 * 2 * 4) represents the triangle.

D

The area as found by the accurate expression in part C is 16.

Answer:

67.5

Step-by-step explanation:

Im pretty sure this is the answer. A triangle is 180º so you do 180-45 and divide it by 2.

Answer:

67.5°

Step-by-step explanation:

The given angle is 45°, so the remaining to angles must collectively make up the rest of the 180°. In this situation, the opposite sides are congruent, and therefore the angles are identical. So, from the remaining 135° that need to be accounted for, we would simply divide by 2, and get 67.5°.

Answers

Answer:

x = 2

Step-by-step explanation:

3(x - 1) = 23 - 5(x + 2) ← distribute parenthesis on both sides

3x - 3 = 23 - 5x - 10

3x - 3 = 13 - 5x ( add 5x to both sides )

8x - 3 = 13 ( add 3 to both sides )

8x = 16 ( divide both sides by 8 )

The original price of a shirt is $16.00. The price of the shirt is discounted by 20%, then a 4% sales tax is added. What is the final price of the shirt after the discount is taken off and sales tax added?

Answers

Answer:

$13.31

Step-by-step explanation:

blehn  b;eoj

Answer:

$13.31

Step-by-step explanation:

First, take the original price and apply the discount of 20% by converting the percentage into a decimal (0.2)

16 x 0.2

= 3.2

Next, take away that amount from the original price

16 - 3.2

= 12.8

Now calculate the tax with the new price by converting the percentage into a decimal (0.04)

12.8 x 0.04

= 0.512

Finally, add the tax to the new amount

12.8 + 0.512

= 13.312

Round if necessary.

Step-by-step explanation:

The given expression is :

Taking LHS of the above expression

[tex]\dfrac{2-\sqrt5}{2+3\sqrt5}[/tex]

Rationalizing both denominator and numerator.

[tex]\dfrac{2-\sqrt5}{2+3\sqrt5}\times \dfrac{2-3\sqrt5}{2-3\sqrt5}=\dfrac{4-6\sqrt5-2\sqrt5+15}{2^2-(3\sqrt5)^2}\\\\=\dfrac{19-8\sqrt5}{4-45}\\\\=\dfrac{19-8\sqrt5}{-41}\\\\=\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})[/tex]

Equation (1) becomes,

[tex]\dfrac{\sqrt5 \times 8}{41}+(\dfrac{-19}{41})=\sqrt 5\ x+y[/tex]

Equating both sides,

[tex]x=\dfrac{8}{41}[/tex] and [tex]y=\dfrac{-19}{41}[/tex]

Hence, this is the required solution.

Now I can not be 100% sure since I can not see the chart, but I can go off of logic. So let´s get started

First we can eliminate answer B. Answer B does not make ANY sense. Why would the number 3 make a difference.

Now answer A and D. These answers are basically the same. So if one is true, the other is as well. For D, if it were the same number, just negative and positive, the sum would be 0.

So this makes A and D true

Answer C is backed up by answer D as well. They can only be the same distance if one is positive and the other is negative

Help please will give you points

Answers

Answer:

16

Step-by-step explanation:

From the question given above, the following data were obtained:

Sum of N term (Sₙ) = 292

2nd term (T₂) = 8.5

5th term (T₅) = 13

Number of terms (N) =?

Next, we shall determine the first term (a) and the common difference (d) of the series. This can be obtained as follow:

T₂ = a + d

8.5 = a + d ........ 1

T₅ = a + 4d

13 = a + 4d ........ 2

Subtract equation 1 from equation 2 i.e

(2) – (1)

.. 13 = a + 4d

– 8.5 = a + d

¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯

4.5 = 3d

Divide both side by 3

d = 4.5 / 3

d = 1.5

Substitute the value of d into any of the equation to obtain the value of a. Here, we shall use equation 1.

8.5 = a + d

d = 1.5

8.5 = a + 1.5

Collect like terms

8.5 – 1.5 = a

a = 7

Finally, we shall determine the number of terms as follow:

Sum of N term (Sₙ) = 292

Common difference (d) = 1.5

First term (a) = 7

Number of terms (N) =?

Sₙ = n/2[2a + (n – 1)d]

292 × 2 = n[(2 × 7) + (n – 1)1.5]

584 = n[14 + 1.5n – 1.5]

584 = n[12.5 + 1.5n]

584 = 12.5n + 1.5n²

Rearrange

1.5n² + 12.5n – 584 = 0

Using formula method, the value of n can be obtained as follow:

a = 1.5

b = 12.5

c = –584

n = –b ± √(b² – 4ac) / 2a

n = –12.5 ± √(12.5² – 4 × 1.5 × –584) / 2 × 1.5

n = –12.5 ± √(156.25 + 3504) / 3

n = –12.5 ± √(3660.25) / 3

n = –12.5 ± 60.5 / 3

n = –12.5 + 60.5 / 3 or –12.5 – 60.5 / 3

n = 4 /3 or –73 / 3

n = 16 or –73 / 3

Since the number of terms can not be negative, therefore, the number of term is 16

Interior angle is (12x+12)°.
The exterior angle is (5x+15)°

how many sides does the polygon have?​

Answers

Answer: It has 4 sides

Answer:

6 sides

Step-by-step explanation:

The interior angle and exterior angle sum to 180° , then

12x + 12 + 5x + 15 = 180

17x + 27 = 180 ( subtract 27 from both sides )

17x = 153 ( divide both sides by 17 )

x = 9

Then

exterior angle = 5x + 15 = 5(9) + 15 = 45 + 15 = 60°

The sum of the exterior angles of a polygon = 360° , thus number of sides n is

n = 360° ÷ 60° = 6

Peter has a coupon for 15% off the price of any item in a sporting good store he wants to buy a pair of sneakers that are priced at $36.99 about how much will it take sneakers cost after the discount

Answers

Answer:

$31.44

Step-by-step explanation:

According to the word problem, Peter has a coupon for 15% OFF.

This means the price will reduce by 15%.

To solve this, first, change the percentage (15%) to decimal form.

To do this, divide the percentage by 100.

15 / 100 = 0.15.

0.15 is the decimal form of 15%.

Next, multiply the decimal form of the percentage by the price.

36.99 x 0.15 = 5.5485

Lastly, subtract the product from the original price.

36.99 - 5.5485 = 31.4415

In this case, the product goes above the hundredths place.

So we must round 31.4415 to the hundredths place.

31.4415 ≈ 31.44

Therefore, the sneakers are $31.44 after the discount of 15%.

A teacher's grades are normally distributed with a mean of 75 and a standard deviation
of 8.6. What is the probability that a student will score between 56 and 72?

Answers

Answer:

34.9%

Step-by-step explanation:

Z1=[tex]\frac{56-75}{8.6}[/tex] = -2.21

F(Z1) = 0.9861

Z2=[tex]\frac{72-75}{8.6}[/tex] = -0.35

F(Z2) = 0.6367

P(56<X<72)= 0.9862-0.6367= 0.349 = 34.9%

Lila and 11 of her team members were eating pizza after their volleyball game. There were 4 pizzas and each slice of pizza was 1/6 of a whole pizza. How many total slices of pizza were available for the girls to eat? i need help please

Answers

Answer:

24 slices of pizza were available to be eaten

Step-by-step explanation:

Here, we want to get the number of slices of pizza available to be eaten

From the question;

a slice is 1/6 of a pizza

So the number of slices in a full pizza would be 1 divided by 1/6 = 1* 6/1 = 6 slices

In each of the pizzas, there were 6 slices;

So the number of slices in 4 pizzas would be 6 * 4 = 24 slices

So, 24 slices of pizza were available to be eaten by the girls

A pet store donated a percent of every sale to hospitals. The total sales were ​$8,900 so they store donated ​$178. What percent of ​$8,900 was donated to hospitals?

Answers

Answer:

2%

Step-by-step explanation:
