NEED HELP ASAP PLEASE!!!

Answer:

$522.50

Step-by-step explanation:

To find the price, multiply 950 by 0.55

950(0.55)

= 522.5

So, the sale price will be $522.50

Answer:

A

Step-by-step explanation:

In order to multiply a whole number by a fraction, you can write the whole number in fraction form. -12 can also be written as    [tex]\frac{-12}{1}[/tex].

Now you can write out    [tex]\frac{-12}{1}[/tex]  ×  [tex]\frac{20}{21}[/tex]  

Multiply the numerators by each other and the denominators by each other to create one fraction.

-12 × 20 = -240     and 1 × 21 = 21

  [tex]\frac{-12}{1}[/tex]  × [tex]\frac{20}{12}[/tex]   = [tex]\frac{-240}{21}[/tex]      and now you can simplify the fraction by finding the greatest common factor of the denominator and numerator.   -240 and 21 have the greatest common factor of 3. Divide each side by 3 and get the fraction -80/7

Answer:

10 carrots

Step-by-step explanation:

So we have 6:8 which is 3:4, meaning that something needs to be changed

Solve for x assuming that we have 6 cabbages

1/3=6/x

x=18

Now we have 6:18, which is 1:3 simplified

There are already 8 carrots so subtract 8

18-8=10

Answer:2.0%

Step-by-step explanation:

The interest rate required to get a total amount of $33,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 20 years is 2.048% per year.

r = n[(A/P)1/nt - 1]

r = 1 × [(33,000.00/22,000.00)1/(1)(20) - 1]

r = 0.0204802

Then convert r to R as a percentage

R = r * 100

R = 0.0204802 * 100

R = 2.048%/year

The interest rate required to get a total amount of $33,000.00 from compound interest on a principal of $22,000.00 compounded 1 times per year over 20 years is 2.048% per year.

Given:

Some boxes are fully colored.

Each fully colored ten block represents 1 whole.

The number of colored boxes will be divided into 11 equal part.

To find:

The number of squares need to be colored on each of the 10 blocks.

Step-by-step explanation:

From the given figure, it is clear that,

Number of colored box = 55

The number of colored box will be divided into 11.

[tex]\dfrac{55}{11}=5[/tex]

Therefore, 5 squares need to be colored on each of the 10 blocks.

Answer:

A. Multiply 3x−3y=1 by 2, and multiply −2x+4y=2 by 3.

Step-by-step explanation:

Given

[tex]3x - 3y = 1[/tex]

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

Required

A good first step

A good first step is to eliminate x and this is done as follows:

Multiply [tex]3x - 3y = 1[/tex] by 2 (gotten from coefficient of x in the second equation)

Multiply [tex]-2x+ 4y = 2[/tex] by 3 (gotten from coefficient of x in the first equation)

This gives:

[tex]6x - 6y = 2[/tex]

[tex]-6x + 12y = 6[/tex]

Add both equations

[tex]6x - 6x - 6y + 12y = 2 + 6[/tex]

[tex]6y = 8[/tex]

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

Hence (a), is true

Answer:

There are no solutions

Step-by-step explanation:

9x+18−5x=2+4x

Step 1: Simplify both sides of the equation.

9x+18−5x=2+4x

9x+18+−5x=2+4x

(9x+−5x)+(18)=4x+2(Combine Like Terms)

4x+18=4x+2

4x+18=4x+2

Step 2: Subtract 4x from both sides.

4x+18−4x=4x+2−4x

18=2

Step 3: Subtract 18 from both sides.

18−18=2−18

0=−16

Answer:

There aren't any values of x that would make the equation true.

Answer:

sin 15° = 0.2588

Step-by-step explanation:

The half angle formula is:

[tex]\sin{(\frac{x}{2})} = \pm \sqrt{\frac{1 - \cos{x}}{2}}[/tex]

sin 15°

The double of 15º is 30º. First quadrant, so the sine is positive.

[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}}[/tex]

Since [tex]\cos{30} = 0.866[/tex]

[tex]\sin{15} = sqrt{\frac{1 - \cos{30}}{2}} = \sqrt{\frac{1 - 0.866}{2}} = 0.2588[/tex]

sin 15° = 0.2588

Answer:

x = -0.35

Step-by-step explanation:

tep 1 - Multiply 64 and 0.5x. The answer ends up being 32x

Step 2 - You need to get all of the variables on one side and the regular numbers on the other side. To do that, you need to subtract 2.5x from each side so you are left with the equation -10.5 = 29.5x

Step 3 - The final step is to isolate the variable. To do this, you divide each side by 29.5 meaning that x = -0.35

Answer:

The cost of 8 balls is Rs $ 120.

Step-by-step explanation:

Given that 15 balls cost Rs $ 225, to determine the cost of 8 balls it is necessary to perform the following mathematical calculation:

(225/15) x 8 = X

15 x 8 = X

120 = X

Thus, the cost of 8 balls is Rs $ 120.

Answer:

The amplitude = 2b, and the verticle shift = 2, which means it has been shifted down 2 units.

Step-by-step explanation:

The highest point is when y = 0 and the lowest point is when y = -4. The vertical distance between the peak and valley is 4 units, which cuts in half to 2. This is the amplitude. It's the vertical distance from the center to either the peak or valley.
