Mr. Williams asks to buy 12 of a pan of brownies that is 23 full.

Answer:

y = 6

Step-by-step explanation:

This is a special right triangle with angle measures 90° 60° 30°

the side length that sees angle measure 30 is represented with x

the side length that sees angle measure 90 is represented with 2x

and the side length that sees angle measure 60 is represented with x√3

the side length that sees angle measure 90 is given as 4√3 which means 2x = 4√3 divide both sides by 2

x = 2√3 now to find y, we need to multiply this value by √3

2√3 × √3 = 2 × 3

Answer: the percentage you would get the number two would be 10% out of 100 I believe. Hope it helped!

Answer:

5. F

6. C

Step-by-step explanation:

5. the mode is all the variables added together which is 100 or 100% divided by the number of them which is 4. 100 divided by 4 is 25 or 25%. The one that's equal to 25% is F which is soccer.

6. The relative frequency from what I can tell is the percentages of each of them. You just have to see how much space each of them takes up. C should be the answer.

Hopefully these are correct.

Answer:

130.25 ft.

Step-by-step explanation:

The semi circle has a length 1/2 of the circumference of the circle with a diameter of 25

C = πd = 3.14(25)

So, the semi circle has a length = 1/2(3.14)25) = 39.25

The distance for the rectangle = 33 + 25 + 33 = 91

Therefore, the total perimeter = 91 + 39.25 = 130.25

ok so I couldn't find what the answer was and there didn't seem to be a virus. Soooo I dunno what that link is. The account that posted it was a bot if you click on the profile it says it deactivated.

Answer:

43°

Step-by-step explanation:

p + 7° + 3p+ 1° = 180° ( Being linear pair)

4p + 8° = 180°

4p = 180° - 8 °

4p = 172°

p = 172° / 4

p = 43°

Answer:

340 liters

Step-by-step explanation:

This means that Tapiwah raked x plus 5% of x leaves. Knowing that Tapiwah actually raked 357 liters, we can find the value of x as follows. So, Adam raked 340 liters of leaves.

289 196 248 379 319 276 198 349

(in order) 196, 198, 248, 276, 289, 319, 349, 379  there are eight numbers.

--------------------------------------------------------------------------------------

196, 198, 248, 276

since the median is between 198 and 248, we must add both numbers together and divide them by two:

(198 + 248) ÷ 2

= 446/2

--------------------------------------------------------------------------------------

289, 319, 349, 379

since the median is between 319 and 349, we must add both numbers together and divide them by two:

(319 + 349) ÷ 2

= 668/2

--------------------------------------------------------------------------------------

Answer:

p-3 is the correct answer

Answer:

p - 3

Step-by-step explanation:

let x = number of pretzels terry ate and p = the amount of pretzels susan ate

If Terry ate 3 less than Susan than

x would equal p - 3

so your answer would be p - 3

Answer:

x = 120

The < sign means less than.

38 is less than 25, but it is less than 40 and 120.

Carbon-14 will take 19,035 years to decay to 10 per cent.

A radioactive half-life refers to the amount of time it takes for half of the original isotope to decay.

An exponential decay can be described by the following formula:

[tex]N(t)=N_oe^{-\lambda t}[/tex]

Where:

No  = The quantity of the substance that will decay.

N(t) = The quantity that still remains and has not yet decayed after a time t

[tex]\lambda[/tex]    = The decay constant.

One important parameter related to radioactive decay is the half-life:

[tex]t_{1/2}=\dfrac{Ln(2)}{\lambda}[/tex]

If we know the value of the half-life, we can calculate the decay constant:

[tex]\lambda =\dfrac{ln(2)}{t_{1/2}}[/tex]

Carbon-14 has a half-life of 5,730 years, thus:

[tex]\lambda =\dfrac{ln(2)}{5730}[/tex]

[tex]\lambda[/tex] = 0.00012097

The equation of the remaining quantity of Carbon-14 is:

[tex]N(t)=N_oe^{-0.00012097t}[/tex]

We need to calculate the time required for the original amount to reach 10%, thus N(t)=0.10No

[tex]0.10N_o=-N_oe^{-0.00012097t}[/tex]

Simplifying:

[tex]0.10=e^{0.00012097t}[/tex]

Taking logarithms:

ln(0.10) = -0.00012097t

Solving for t:

[tex]t=\dfrac{Log0.10}{-0.00012097}[/tex]

t = 19035 years

Carbon-14 will take 19,035 years to decay to 10 per cent.

Answer:

327

Step-by-step explanation:

Answer:

Step-by-step explanation:

25% of a hundred is one-fourth and because there are six students in a fourth of the whole we are multiplying four and six. 6x 4 is 24.

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

25% = 6 students

100% = 24 students

The total number of students in Mr. Foster's class is 24.

The percentage is calculated by dividing the required value by the total

value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of students who chose an amber background = 6

25% of Mr. Foster's class chose an amber background for their school picture.

This means,

25% = 6

The total number of students = 100%

Now,

25% = 6 students

Multiply 4 on both sides.

4 x 25% = 4 x 6 students

100% = 24 students

Thus,

The total number of students in Mr. Foster's class is 24.

Step-by-step explanation:

Don't use 0 (or any other number) to replace θ. Use a letter variable such as x.

tan(x) = 7/24

sin(x)/cos(x) = 7/24

sin(x) = 7/√(7²+24²) = 7/√625 = 7/25

Answer:

the future value is $5,750.01

Step-by-step explanation:

The computation of the future value is shown below;

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $5,000 × (1 + 0.035 ÷ 12)^4 × 12

= $5,000 × (1 + 0.2916%)^48

= $5,750.01

Hence, the future value is $5,750.01
