Answer:

465 miles

Step-by-step explanation:

So you have the ratio 1 cm: 110 mi, so you can multiply both sides of this ratio by 4.5 to get

4.5 cm: 465 mi

Hi there! :)

If you created 5 circles cut into thirds, you would create 15 1/3 pieces.

You can also use the KCF method to solve this!

Answer:

4.61% increase (round up as needed)

Step-by-step explanation:

Subtract the smaller amount from the larger to find the dollar difference

[tex]68-65=3[/tex]

Then divide the difference by the original amount

[tex]3/65=0.0461[/tex]

Move the decimal point over two spaces (multiply by 100) to get your percentage

0.0461=4.61%

Round up as needed.

Answer:180

Step-by-step explanation:

Since 15% of 400=60 and 40%=160 the total of this combined is 220. 400-220=180 which is the amount of purple marbles

Answer:

140 zombies

Step-by-step explanation:

Since this is a proportions problem and we are given three values and a variable we must solve for which is the number of zombie soldiers she can raise (z) with 10 dark power crystals. Therefore, we can use the rule of three to solve for this, in which we multiply the diagonal values and divide by the last remaining value in order to solve for the variable like so...

1 crystal <===>  14 zombies

10 crystals  <===>   Z zombies

(10 * 14) / 1 = 140 zombies

option third is correct answer

In parallelogram ,opposite sides are equal.

x+3=2x-6

solve the value you will get x=9

Hey again!

The solution to the given system is (0, -10)

To solve using elimination, we have to add the equations together, and the "y"s will cancel out, and then solve the equations:

5x - 10 = 6x - 10

Now solve.

Add "10" to both sides:

5x = 6x

Subtract "5x" from both sides

0 = x

Now, we plug in the solved "x" value in an equation to solve for "y".

5(0) + y = -10

y = -10

We now know that the solution to the given system is (0, -10)

Hope this helps! Have an amazing day, and remember, you've got this!!

The solution to the given system of linear equations is (0, -10) which is determined by the elimination method.

A linear equation is defined as an equation in which the highest power of the variable is always one.

The system of linear equations is given in the question:

-y - 10 = 6x    ....(i)

5x +y = -10    ....(ii)

To solve using elimination, we have to add the equations (i) and (ii) together, and the "y" will be eliminated, and then solve the equations:

⇒ 5x - 10 = 6x - 10

Add "10" to both sides of the above equation

⇒ 5x = 6x

Subtract "5x" from both sides

⇒ 0 = x

⇒  x = 0

Now, substitute the value of x = 0 in equation (ii) to solve for "y".

⇒ 5(0) + y = -10

⇒ y = -10

Therefore, the solution to the given system of linear equations is (0, -10).

Answer:

Step-by-step explanation:

Answer:

If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]

Step-by-step explanation:

We are given the function: [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we need to find the value of f(a+2)

For finding the value of f(a+2) we will put x= a+2

We have [tex]f(x)=3(x+5)+\frac{4}{x}[/tex]

Put x = a+2

[tex]f(a+2)=3(a+2+5)+\frac{4}{a+2}\\Solving:\\f(a+2)=3(a+7)+\frac{4}{a+2}\\Taking\:LCM\\f(a+2)=\frac{3(a+7)(a+2)+4}{a+2}\\f(a+2)=\frac{3(a^2+2a+7a+14)+4}{a+2}\\f(a+2)=\frac{3(a^2+9a+14)+4}{a+2}\\f(a+2)=\frac{3a^2+27a+42+4}{a+2}\\f(a+2)=\frac{3a^2+27a+46}{a+2}[/tex]

So, If [tex]f(x)=3(x+5)+\frac{4}{x}[/tex] we get [tex]\mathbf{f(a+2)=\frac{3a^2+27a+46}{a+2}}[/tex]

Answer:

The love seat cost $117.

Step-by-step explanation:

Given that,

A sofa and a love seat together costs $351.

Let love's seat = x

Sofa's seat = 2x

ATQ,

x+2x = $351

3x = $351

[tex]x=\dfrac{351}{3}\\\\x=\$117[/tex]

So, the love seat cost $117.

Answer:

a) h = 15

b) x = 4

Step-by-step explanation:

a) set up a proportion:

  5 = h

   8     24

cross-multiply:

8h = 120

h = 15

b) x + 5 = x + 5 + 15

   5x + 1    5x + 1 + 35

cross-multiply:

(x + 5)(5x + 36) = (5x + 1)(x + 20)

5[tex]x^{2}[/tex] + 61x + 180 = 5[tex]x^{2}[/tex] + 101x + 20

180 = 40x + 20

160 = 40x

x = 4

Answer choice D

Step-by-step explanation:

So we need to get r to the right side. First we can multiply by 3 to get rid of the fraction:

3V=4[tex]\pi[/tex][tex]r^{3}[/tex]

Then we can divide both sides by 4[tex]\pi[/tex] to get r by itself:

[tex]\frac{3V}{4\pi } = r^{3}[/tex]

Then cube both sides:

[tex]\sqrt[3]{\frac{3V}{4\pi } } =r\\[/tex]

Answer:

Parallel

Step-by-step explanation:

2x + 3y = 15

3y = -2x + 15

y = -2/3x + 5 (slope = -2/3)

4x + 6y = -48

6y = -4x - 48

y = -2/3x - 8 (slope = -2/3)

Since the slopes are the same, they are parallel.

Step-by-step explanation:

Hey there!

Given equations are;

2x+3y = 15...............(i)

4x+6y = -48…………(ii)

From eqaution (i)

2x+3y = 15

Slope (m1) = (-coefficient of x)/(coefficient of y)

Slope (m2) = (-2)/(3)

Therefore, slope (m1) = -2/3.

From eqaution (ii).

4x+6y= -48

Slope (m1) = (-coefficient of x)/(coefficient of y)

Slope (m2) = (-4)/6

Therefore, slope (m2) = -2/3.

Now;

Condition of parallel lines: m1=m2

-2/3 = -2/3

So, they are parallel.

thank you! have a good day ahead

Step-by-step explanation:

Since we know that as the angles are in linear pair then their sum equals to 180°

Given

One angle = 47°

Let the other angle be x then

x + 47° = 180° {being linear pair }

x = 180° - 47°

Therefore x = 133°

The measure of the other angle is 133°

Hope it will help :)❤

Answer:

133°

Step-by-step explanation:

they form 180° together, so 180-47=133°
