The correct choice is [tex]a^2+15^2=17^2[/tex]

Step-by-step explanation:

We will apply the Pythagoras formula to calculate the perpendicular length (a).

Pythagoras formula [tex]=(base)^2+(perpendicular)^2=(Hypotenuse)^2[/tex]

The right angle is formed between [tex]a[/tex] and [tex]15\ m[/tex] length.

So [tex]17\ m[/tex] is the hypotenuse opposite to right angle is the longest side and called the hypotenuse.

So

[tex](a)^2+(15)^2=17^2[/tex]

[tex]a=\sqrt{17^2-15^2}= 8\ m[/tex]

So the measure of side length [tex]a[/tex] is [tex]8\ m[/tex].

That can be calculated from the option A that is [tex](a)^2+(15)^2=17^2[/tex].

Answer: The perimeter of the scale drawing is [tex]30[/tex].

Step-by-step explanation:

You need to analize the information provided in the exercise.

You know that the perimeter of rectangle is [tex]450[/tex] and the scale factor Natalie used to create the scale drawing, was:

[tex]scale\ factor=\frac{1}{15}[/tex]

From this you can identify that, in order to find the perimeter of the scale drawing of the triangle (Which can be represented with [tex]P_2[/tex]), you must multiply the original perimeter ((Which can be represented with [tex]P_1[/tex]), by the scale factor Natalie used.

Therefore, you get that the perimeter is:

[tex]P_{2}=\frac{1}{15}P_1\\\\P_2(\frac{1}{15})(450)\\\\P_2=30[/tex]

Answer: Janessa has 10 Amari has 34

The number of blue berries with Janessa and Amari are 10 and 34 respectively.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Robert who has 20 blueberries such that he has 10 more blueberries than Janessa and 14 fewer blueberries than Amari.

Assume that the number of blue berries with Janessa and Amari are x and y respectively. We can write the following modelled equations as -

20 = x + 10

20 = y - 14

Solving, we get -

x = 10

y = 34

Therefore, the number of blue berries with Janessa and Amari are 10 and 34 respectively.

Answer:

The number of number of bags of snacks = m  = 176

The number of beverages supplied = m + 19  = 176 +9 = 185

Step-by-step explanation:

Let us assume the number of bags of snacks = m

So, the number of beverages supplied = m + 19

Total number of items supplied  =  371

⇒ Number of (snacks + beverages) supplied=  371

⇒   m + (m +19)  = 371

or, 2 m = 371 - 19 =  352

or, m =  352 / 2 = 176  

⇒  m  = 176

Hence the number of number of bags of snacks = m  = 176

So, the number of beverages supplied = m + 19  = 176 +9 = 185

Answer:

2. A

Step-by-step explanation:

1. The terms seem to be increasing by a constant of 7.

11+7=18

18+7=25

25+7=32

Therefore, the next two terms should be 32+7 and 32+7+7. This equals 39 and 46.

2. The terms in this pattern are being divided by 6

180/6=30

30/6=5

In order to find the missing number before 180, we need to multiply 180 by 6. 180 times 6 is equal to 1080.

The area swept by the minute hand in 12 minutes is 181.58 cm²

Step-by-step explanation:

In the circle clock

∵ The minute hand is swept by 12 minutes

∵ The central angle between each two consecutive minutes = 6°

∴ The central angle when the minute hand swept 12 minutes =

   6 × 12 = 72°

∵ The area of a sector of a circle = [tex]\frac{x}{360}*\pi r^{2}[/tex] ,

   where r is the radius of the circle and x is the central angle of

   the sector

∵ The radius of the circle is the length of the minute hand

∵ The minute hand in a clock is 17 cm long

∴ r = 17 cm

∵ The measure of the central angle is 72°

∴ x = 72°

- Substitute these values in the rule of the area of a sector

∵ Area = [tex]\frac{72}{360}*\pi (17)^{2}[/tex]

∴ Area = 181.58 cm²

The area swept by the minute hand in 12 minutes is 181.58 cm²

Answer:

The remaining wood will be 1.25 inches shorter.

Step-by-step explanation:

Only 10 cuts are required to cut the board into 11 equally sized lengths.  Thus, the length of the board after these cuts have been made will be

10(0.125 inches), or 1.25 inches, shorter.

By making 10 cuts, the total length of the board will be reduced by 1.25 inches due to the saw blade reduction. After converting this to feet, Michael will have approximately 15.896 feet of board left.

Michael has a 16-foot board that he plans on cutting into 11 equal lengths. This means he will need to make 10 cuts (as the 11th 'cut' is actually the end of the board not actually needing a cut). The saw blade will decrease the length of the board by -0.125 inches for each cut. To solve this, we multiply the number of cuts by the length that will be reduced by the saw blade. That gives us 10 x -0.125 = -1.25 inches. That means that the total usable length of the board will be reduced by 1.25 inches. We need to convert this to feet since the original length of the board is in feet. There are 12 inches in foot, so -1.25 inches is about -0.104 feet. Thus, the total length of the board after all the cuts will be 16 - 0.104, or approximately 15.896 feet.

The answer is 11

Step-by-step explanation:

Final answer:

The distance between the top of the escalator and the ground floor is approximately 12 feet.

Explanation:

To find the distance between the top of the escalator and the ground floor, we can use trigonometry. We have the length of the escalator (16 feet) and the angle of depression (42.51 degrees). The distance we need to find is the opposite side of the right triangle formed by the top of the escalator, the floor, and the length of the escalator. We can use the sine function to find this distance.

The formula is sin(angle) = opposite/hypotenuse. Plugging in the values, we get sin(42.51) = opposite/16. Solving for opposite, we have opposite = sin(42.51) * 16.

Using a calculator, we find that opposite ≈ 12.014 feet. Rounding to the nearest foot, the distance between the top of the escalator and the ground floor is approximately 12 feet.

Answer:

y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{5}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{1}{2}[/tex], thus

y = - [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (- 3, 4) into the partial equation

4 = [tex]\frac{3}{2}[/tex] + c ⇒ c = 4 - [tex]\frac{3}{2}[/tex] = [tex]\frac{5}{2}[/tex]

y = - [tex]\frac{1}{2}[/tex] x + [tex]\frac{5}{2}[/tex] ← equation of line

Step-by-step explanation:

Mrs. Bailey had a 75% decrease in the number of candies she had after giving away 9 out of the original 12 pieces.

To calculate the percent decrease of candy Mrs. Bailey had, we begin by identifying the initial amount and the final amount of candy. Mrs. Bailey started with 12 pieces and ended with 3 pieces, which means she gave away 12 - 3 = 9 pieces of candy. To find the percent decrease, we use the formula: “part over total, times one hundred, equals percent.” Here, the “part” is the amount of candy she gave away (9), and the “total” is the original amount she had (12).

The formula for the percent decrease is:

9 / 12 × 100 = 75%

So, the percent decrease in the number of candies Mrs. Bailey had is 75%.

Step-by-step explanation:

Monica makes $550 and Phil makes $275 per week

Step-by-step explanation:

Monica and Phil each have part-time jobs

We need to find how much each person make​s

Assume that Phil makes $x in a week

∵ Phil makes $x per week

∵ Monica makes twice as much money in a week as Phil

∴ Monica makes = $2x per week

∵ The total of their weekly earnings is 825

- Add their weekly earnings

∴ x + 2x = 825

- Add the like terms

∴ 3x = 825

- Divide both sides by 3

∴ x = 275

- Find 2x

∴ 2x = 2(275) = 550

Monica makes $550 and Phil makes $275 per week

Step-by-step explanation:

An expression can be written in rational number by writing 1 in the denominator then it will become a fraction and  a rational number

Answer:

A rational numbers can be defined as numbers that can be expressed as the quotient between two integers.

This means that a whole number can be expressed as a rational number by just adding 1 into its denominator

[tex]2 \implies \frac{2}{1}[/tex]

That way the whole number would be a rational number, becase 2 and 1 are integers.

Therefore, an expression can be written in rational form by  writing it as a fraction with a denominator of 1.

Answer:

Charlie used 4 20-cent stamps and 8 32-cent stamps.

Step-by-step explanation:

Let the number of 20 cents stamps be [tex]x[/tex]. Then, as per question, Chalie used twice as many 32-сent stamps as 20 cent stamps.

Therefore, number of 32-cent stamps is [tex]2x[/tex].

Now, total cost of the stamps is $ 3.36 = 336 cents

Cost of 1 20-cent stamp is 20 cents. So, cost of [tex]x[/tex] 20-cent stamps is [tex]20x[/tex]. Similarly, cost of [tex]2x[/tex] 32-cent stamps is [tex]32(2x)=64x[/tex]

Total cost = [tex]20x+64x=84x[/tex]

As per question,

[tex]84x=336\\x=\frac{336}{84}=4[/tex]

Number of 20-cent stamps = [tex]x = 4[/tex]

Number of 32-cent stamps = [tex]2x=2\times 4=8[/tex]

So, Charlie used 4 20-cent stamps and 8 32-cent stamps.

Answer:

No. of 32 cent stamps = 8

and that of 20 cent stamps = 4

Explanation:

Let no. of 32 cent stamps used be x and the number of 20 cent stamps used be y.

We are given that total postage on a package put by Charlie by using only 32 and 20 cent stamps is equal to $3.36.

So, since 100 cents make one dollar, $3.36 = 336 cents.

So,

32x + 20y = 336

Also we are given that Charlie used twice as many 32 cent stamps as 20 cent stamps which can be written as,

x = 2y

Substituting this equation in previous equation we get

32 [tex]\times[/tex]2y + 20y = 336

=> 64y + 20y = 336

=> 84y = 336

=>y = 4

Putting the value of y in x = 2y we get x = 2*4 = 8

So, no. of 32 cent stamps = 8 and that of 20 cent stamps = 4
