Answer:

10,990 legs

Step-by-step explanation:

There are 7 girls in the bus

= 7 × 2 = 14 legs

Each bag pack there are 7 big cats

= 7 × 7 × 7 × 4= 1372 legs

For every big cats there are 7 small cars

= 7×7×7×7×4= 9,604 cats

Therefore the total legs in the bus can be calculated as follows

= 14 +1372+9604

= 10,990 legs

Hence there are 10,990 legs in the bus

Answer:

it equals 6k but an equivalent expression could be 2k + 4k

Step-by-step explanation:

2k + 4k = 4k + 2k

Answer:

6k

Step-by-step explanation:

You can combine both of these terms because they both have the same variable (k). We know that 4+2=6, and the variable stays the same, 6k.

Answer:

272/-13 or −20.923

Step-by-step explanation:

To solve this equation you need to isolate the variable.

First, add 71 to both sides

-13x-71+71=201+71

-13x=272

Then, divide both sides by -13

-13x/-13=272/-13

So, x=272/-13 or −20.923

Answer:

x = 10

Step-by-step explanation:

Okay the two sides are going to equal the same measure soo...

4x + 9 = 11x - 61 (Subtract 4x on both sides)

9 = 7x - 61 ( add 61 on both sides)

70 = 7x (divide both sides by 7)

10 = x

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180 °.

In triangles ΔJMK and ΔLMK, then we have

∠JMK = ∠LMK = 90°          (Right angle)

∠JKM = ∠LKM                    (Given)

KM = KM                             (Common side)

The triangles ΔJMK and ΔLMK are congruent with each other. Then the sides JK and KL will be equal. Then the value of 'x' will be given as,

KL = JK

11x - 61 = 4x + 9

11x - 4x = 61 + 9

7x = 70

x = 70 / 7

x = 10

The triangles ΔJMK and ΔLMK are congruent. Then the value of the variable 'x' will be 10.

Answer:

Last week, Clay had a beginning balance of $60 in his account. He wrote 4 checks for $20 each from his checking account, withdrew another $30, and finally made a deposit of $96.

Part A: Write an expression and your answer to show his final account balance at the end of the week.

Answer:

<1 =100 (check explanation for why)

<2 = 80 (check explanation for why)

<3 = 100 (check explanation for why)

Step-by-step explanation:

You can get <1 from the given angle being a linear pair  to <1, so:

180= 80+ <1

100= <1

You can get <2 from being a linear pair to <1, so:

180 = 100 + <2

80 = <2

You can get <3 from being a linear pair to <2

180 = 80 + <3

100= <3

Answer:

m<1= corresponding

m<2=vertical angle

Answer:

The expression that gives the length of the pool is [tex]\sqrt{A}[/tex] - 5

Step-by-step explanation:

Assume that the length of the pool is x feet

∵ The length of the pool is x feet

∵ The wide of the walkway around the pool is 5 feet

∴ The total length of the pool with the walkway = (x + 5) feet

∵ The area of the entire plot, including the walkway, is A square feet

∴ The area of the entire plot, including the walkway = A feet²

∵ The area of the square = (length)²

→ Substitute the length by (x + 5)

∴ The area of the entire plot, including the walkway = (x + 5)² feet²

→ Equate it by A

∴ A = (x + 5)²

→ To find x take square root for both sides

∵ [tex]\sqrt{A}[/tex] = [tex]\sqrt{(x+5)^{2}}[/tex]

→ Cancel the square root of the right side by power 2

∴ [tex]\sqrt{A}[/tex] = x + 5

→ Subtract 5 from both sides

∵ [tex]\sqrt{A}[/tex] - 5 = x + 5 - 5

∴  [tex]\sqrt{A}[/tex] - 5 = x

→ x represents the length of the pool

∴ The length of the pool is  [tex]\sqrt{A}[/tex] - 5 feet

∴ The expression that gives the length of the pool is [tex]\sqrt{A}[/tex] - 5

The length of the pool will be √A-10.

Area is defined as the total space taken up by a flat surface or shape of an object.

Given that, A square plot of land will be fully used for a square swimming pool with a 5-foot wide walkway around it. The area of the entire plot, including the walkway, is A square foot.

The area of a square is side².

Let the side of the walkway be (x+10)

A =  (x+10)²

√A = x+10

x = √A-10

Hence, The length of the pool will be √A-10.

Step-by-step explanation:

5y-4 has to equal 81 in order for the two triangles to be congruent.

The sum of the interior angles of a triangle is always 180 degrees.

180-132=48

x+4=48

x=48-4

x=44 degrees

Answer:

45 feet

Step-by-step explanation:

Area of a rectangle = length × width

Area of the rectangle = 1,125 square feet

Length of the rectangle = x feet

Width of the rectangle = 25 feet.

What is the length of the parcel of land?

Area of a rectangle = length × width

1,125 = x * 25

1,125 = 25x

Divide both sides by 25

x = 1,125 / 25

= 45

x = 45 feet

The length of the parcel of land is 45 feet

When you multiply two negative numbers or two positive numbers then the product is always positive. 3 times 4 equals 12. Since there is one positive and one negative number, the product is negative 12.

Answer:

0.3

Step-by-step explanation:

Given that:

Probability of growing into a healthy plant = probability of success (p) = 75% = 0.75

Number of seeds planted(n) = 9

Probability that exactly 2 don't grow is equivalent to having 7 that grows (9 - 2) = 7 = r

Using binomial distribution formula :

nCr * p^r * (1 - p)^(n-r)

9C7 * 0.75^7 * (1 - 0.75)^(9 - 7)

9C7 * 0.75^7 * 0.25^2

36 * 0.13348 * 0.0625

= 0.3003387

= 0.3

Hence, probability that exactly 2 don't grow is 0.3

Answer:

50 ribbons

Step-by-step explanation:

To find how many ribbons she can make, divide 32 by 0.64:

32/0.64

= 50

So, she can make 50 ribbons from her roll

56

20/35 = 35/x

20x = 32(35)

Divide both sides by 20 to solve for x

X = 1120/20

X = 56

The missing side length of the given image is 56 so x = 56 will be the correct answer.

A line section that can connect two places is referred to as a segment.

Lines are very useful and common in geometry we daily use them.

The line is here! It extends endlessly in both directions and has no beginning or conclusion.

In other words, the line is a straight figure which has zero width and infinite length but if we take a segment then it is called a line segment which will be finite.

Given in the image 3 lines are parallel and intersect two lines that are randomly inclined.

Let's say the missing length is x

By geometrical similarity rule

x/32 = 35/20

x = 32 × 35/20

x = 56 hence 56 will be the missing side length of the given figure.

Answer:

C. Chanterelle mushrooms cost less by $0.90 is correct.

Step-by-step explanation:

1. For the Cremini mushrooms, we know it costs $11.25 for 2/3 lb. So, let's divide this amount by 2 to get the amount of money per 1/3 lb of Cremini mushrooms.

11.25 ÷ 2 = 5.63 when rounded to the nearest cent.

Now, let's multiply this by 3 to get the price of 1 lb of Cremini mushrooms.

5.63 x 3 = 16.89

Therefore, 1 pound of Cremini mushroom is $16.89.

2. For the Chanterelle mushrooms, we know that it cost $7.99 for 1/2 lb. So, let's multiply this amount by 2 to get the price per pound.

7.99 x 2 = $15.98

Therefore, 1 pound of Chanterelle mushroom is $15.98.

3. To find the difference between two prices, subtract the price of the smaller quantity (Chanterelle mushroom) from the larger quantity (Cremini mushroom.)

16.89 - 15.98 = $0.91

Even though this answer doesn't match with the exact answer, because we rounded to the nearest cent, we can agree that C. is correct.

Answer:

Please read the explanied answer below.

Step-by-step explanation:

We also know that a regular polygon has all the angles equal and all sides have the same length.

As we know:

When the number of sides changes, the angle also changes. Therefore, we would get different integers as answer.

For example:

In terms of a triangle:

Exterior angle = 360° ÷ No. of sides

                        = 360° ÷ 3 = 120°

In terms of a rectangle:

Exterior angle = 360° ÷ No. of sides

                        = 360° ÷ 4 = 90°

and in the same way

360° ÷ 5 = 72 °

360° ÷ 6 = 60 °

360° ÷ 8 = 45 °

360° ÷ 9 = 40°

and so on.
