Answer:

5pi/3x180grados/piradianes

900/3=300 grados

Step-by-step explanation:

◈ Area of square room :

[tex]:\implies\sf\:A_s=(side)^2[/tex]

[tex]:\implies\sf\:A_s=(12)^2[/tex]

[tex]:\implies\bf\:A_s=144\:m^2[/tex]

◈ Area of triangular carpet :

[tex]:\implies\sf\:A_t=\dfrac{1}{2}\times base\times perpendicular[/tex]

[tex]:\implies\sf\:A_t=\dfrac{1}{2}\times 10\times 8[/tex]

[tex]\:\implies\sf\:A_t=\dfrac{1}{2}\times 80[/tex]

[tex]:\implies\bf\:A_t=40\:m^2[/tex]

◈ Uncovered area of room :

[tex]:\implies\sf\:\Delta A=A_s-A_t[/tex]

[tex]:\implies\sf\:\Delta A=144-40[/tex]

[tex]:\implies\:\boxed{\bf{\blue{\Delta A=104\:m^2}}}[/tex]

Step-by-step explanation:

Answer:x=8

Step-by-step explanation:Reorder the terms:

10x + -2(6 + x) = 52

10x + (6 * -2 + x * -2) = 52

10x + (-12 + -2x) = 52

Reorder the terms:

-12 + 10x + -2x = 52

Combine like terms: 10x + -2x = 8x

-12 + 8x = 52

Solving

-12 + 8x = 52

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '12' to each side of the equation.

-12 + 12 + 8x = 52 + 12

Combine like terms: -12 + 12 = 0

0 + 8x = 52 + 12

8x = 52 + 12

Combine like terms: 52 + 12 = 64

8x = 64

Divide each side by '8'.

x = 8

Simplifying

x = 8

Answer:

x=5

Answer:

3 hours

Step-by-step explanation:

369 divided by (58+65)

The GCF of 45 and 75 is 15.

So, divide both numbers by 15.

45/15 = 3

7515 = 5

Therefore, the simplified version of the ratio is 3 to 5

Step-by-step explanation:

just plug each coordinates

5=x

18=y

if its tru for both then thats the answer

Answer:

5,8

Step-by-step explanation:

y=4x-2-----(i)

y=x+13----(ii)

Equating equation i and ii we get,

[tex]4x - 2 = x + 13[/tex]

[tex]4x - x = 13 + 2[/tex]

[tex]3x = 15[/tex]

[tex]x = 3[/tex]

[tex]substitutin \: the \: value \: of \: x \: in \: equation \: (i)[/tex]

[tex]y = 4x - 2[/tex]

[tex]y = 4 \times 5 - 2[/tex]

[tex]y = 20 - 2[/tex]

[tex]y = 18[/tex]

Answer:

Step-by-step explanation:

Suppose pieces of chocolate pie served at a restaurant average 350 calories with a standard deviation of 20 calories. Calories have a Normal distribution due to inexact cutting of the pies. Which graph represents the proportion of pieces of pie that have more than 375 calories.

Answer: The z score is used to determine how many standard deviations that the raw score is above or below the mean. If the z score is positive then the raw score is above the mean and for a negative z score means the  raw score is below the mean. The z score is given as:

[tex]z=\frac{x-\mu}{\sigma}[/tex]

Given that: μ = 350 calories, σ = 20 calories, x > 375

[tex]z=\frac{x-\mu}{\sigma}\\\\z=\frac{375-350}{20}=1.25[/tex]

From the graph, The shaded area represents the proportion of pieces of pie that have more than 375 calories

From the normal distribution table, P(x > 375) = P(z > 1.25) = 1 - P(z < 1.25)

= 1 - 0.8944 = 0.1056 = 10.56%

Answer:

585 Feet

Step-by-step explanation:

First, you have to consider how much seconds in a minute. 60.

Then, multiply 75 feet to make it match to 60 seconds. So 60/25. You get 2.4. You multiply 2.4 by 75 to get 180 feet per minute.

Finally, you multiply 180 by 3.25, as it is 3.25 minutes.

Hey there! I'm happy to help!

Let's use the variables A and B to represent the number of pounds used of types A and B.

4.10A+5.30B=640.50

A+B=141

Let's rearrange the bottom equation to solve for B.

A+B=141

Subtract A from both sides.

B=141-A

We can put this value of B into the first equation to solve for the number of pounds of type A Omar used.

4.10A+5.30(141-A)=640.5

We use distributive property to undo parentheses.

4.10A+747.3-5.3A=640.5

We combine like terms.

-1.2A+747.3=640.5

Subtract 747.3 from both sides.

-1.2A=-106.8

Divide both sides by -1.2

A=89

Omar used 89 pounds of type A coffee in this month's blend.

Answer:

[tex]-\frac{19}{8}[/tex]

Step-by-step explanation:

[tex]\frac{1}{4}-\frac{21}{8}=\frac{2}{8}-\frac{21}{8}=\frac{2-21}{8}=-\frac{19}{8}[/tex]

The required number line represents 2 whole intervals (16/8) and then 7 more parts (7/8) from 0, and ends up at the point marked 2 3/8.

In math, a number line can be defined as a straight line with numbers arranged at equal segments or intervals throughout. A number line is typically shown horizontally and can be extended indefinitely in any direction.

To add fractions with different denominators, we need to find a common denominator. In this case, we can use 8 as the common denominator:

1/4 + -21/8

1/4 - 21/8

2/8 - 21/8

-19/8

-2 3/8

To represent 19/8 on a number line, we need to divide the interval between 0 and 3 into 8 equal parts, and then count 23 of these parts from 0.

The number line would look something like below as shown.

Thus, the required number line represents 2 whole intervals (16/8) and then 7 more parts (7/8) from 0, and ends up at the point marked 2 3/8.

Answer:

102.2 miles

Step-by-step explanation:

First, convert the minutes to hours:

101.5/60

= 1.69 hours

Multiply this by 60.4 to find how many miles it covered:

= 102.2 miles

Answer:

The answer is 3.

Step-by-step explanation:

The equation would be: x = 14.95 divided by 4.99, rounded to the nearest one:

14.95 divided by 4.99 = 2.99599...

Normally, I would not round the number to the nearest digit in problems like these, but 2.99599 is quite close to 3, so this might be an exception.

Anyways, that's how I got my answer.

Hope this helped.
