Answer:

Perimeter of rectangle = 30 cm

Step-by-step explanation:

Perimeter of rectangle = (length + width) x 2

-- width or breadth --

Perimeter

= (10 + 5) * 2  

= 15 * 2

= 30 cm

Answer:

(-840/13,0) I think? I'm honestly not sure about this one

Step-by-step explanation:

(-30-(-45))/(48-61)=15/-13

(y-y1)=m(x-x1)

y-(-30)=-15/13(x-(-30))

y+30=-15/13(x+30)

y+30=-15/13x+-450/13

y=-15/13x+-840/13

Answer:

x = 11

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~

(7, 1)

(x, 4)

m = [tex]\frac{3}{4}[/tex]

[tex]\frac{4-1}{x-7}[/tex] = [tex]\frac{3}{4}[/tex]

x - 7 = 4

x = 11

Answer:

[tex]\frac{1}{3^{4} }[/tex]

Step-by-step explanation:

You can rewrite 3⁻⁴ as 1/(3⁴) or 1/81 without negative exponents.

The product rule is an exponent rule that states that when you multiply similar bases, the add exponents.

For example, (a²)·(a³) = a²⁺³ = a⁵

You can rewrite 3⁻⁴ as 1/(3⁴) because any number raised to a negative exponent is equal to 1 divided by that number raised to the opposite positive exponent.

So 3⁻⁴ = 1/(3⁴) = 1/81

Another way, you can think of it as "flipping" the base, i.e. (1/3)⁴ = 1/81

Step-by-step explanation:

There are 6 marbles that are either red or green out of 12 total marbles, so you have:

6/12 = 1/2

Answer:

1/2

Step-by-step explanation:

To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:

[tex]\frac{5+1}{12}[/tex] or [tex]\frac{6}{12}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex].

Answer:

15,600 Gallons

Step-by-step explanation:

The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Last used of water = 12000

30% of 12000 = (30/100)12000 = 3600

Water used in the current year = 12000 + 3600 = 15600 gallons.

Hence "The 30% of 12000 is 3600 thus, Jessica's family used 15600 gallons of water".

Answer:

83.96 (approximately)

Step-by-step explanation:

I am not completely sure what the problem is asking, just like the last one, but I believe that you are just supposed to take the inverse of cosine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then cosine. You use the inverse of cosine when two sides are given, but you are not given the angle.

It should look like:

[tex]cos^{-1}(\frac{4}{38})[/tex], which is approximately 83.96.

Hopefully this is right, if not, please let me know. Good luck.

Answer:

Step-by-step explanation:

to prove that, that is a right triangle you use the theorem that the two shorter sides square added equals the longest side squared

so if its a right triangle then 10^2+12^2 will equal 15^2

10^2+12^2=244

15^2=225

225 does not equal 224 so that is not a right angle

Answer:

m= 3/7

Step-by-step explanation:

I'm assuming the question is solve for the variable, m.

First step is to isolate the variable

In other words, let's move everything (but m) from the left side to the right side

To move 7 to the right side, we can either divide both sides by 7 or multiply both sides by 1/7 (both equal the same thing)

7/3m × 1/7 = 1 × 1/7

1/3m = 1/7

Now we must move 1/3 from the left to the right side

We can use the reciprocal, 3/1, to do this

1/3m × 3/1 = 1/7 × 3/1

m = 3/7

Answer:

7

Step-by-step explanation:

The new expression would be: 2(10) / 5 + 3. Using PEMDAS, first multiply 2(10) to get 20. Now you get: 20 / 5 + 3. Using PEMDAS, now divide 20 / 5 to get 4. The new expression is 4 + 3. Now, add to get 7 as your answer.

Answer:

C.

was right on edge 2021

The correct option is (C)

An equation is a mathematical expression that contains an equals symbol.

Given:

Sound travels= 1100 feet per second

Stations are 2 miles apart from each other, i.e., 10560 feet.

Using,

x²/a² + y²/b²=1

So, 2c= 10560

c=5280

and, 2c-2a +3300 = 10560

2a= 3300

a= 1650

So, b²= c² - a²= 25155900

x²/2722500 + y²/25155900=1

Answer:

192 cm^3

Step-by-step explanation:

V = 8 * 6 * 12   =   192 cm^3

Answer:

60 cm ( squared )

Step-by-step explanation:

you can find the area of the trapezoid ( by decomposing it into other shapes ) by separating two triangles, and using the formula to find the area of triangles, which is A= 1/2 ( b x h ) and add the answer to those together ( 16 cm squared and 4 cm squared ), and after that, you can find the area to the rectangle by multiplying the l x w, which is 10 x 4 ( after separating the triangles.). That equals 40, and when you add them all together ( 16 + 4 + 40 ) it equals 60 cm (squared).
