Tasya [4]3 years ago
8 0

Answer:

14 -2i

Step-by-step explanation:

9 + sqrt(-4) - ( -5 + sqrt(-16))

We know the sqrt of a negative number is i * sqrt(number)

9 + isqrt(4) - ( -5 + isqrt(16))

9 + 2i - (-5 + 4i)

Distribute the negative sign

9+2i +5 -4i

Combine like terms

14 -2i

The workers at Cameron's Flower shop are putting 1,323 flowers into vases for a party .Each base must hold exactly 8 flowers .Wh
Alika [10]

Answer:

165

Step-by-step explanation:

How many complete vases can Cameron's Flower shop fill with 8 flowers each, considering they have a total of 1,323 flowers in total.

All you have to do is divide 1,323 by 8 to get = 165.375 or 165 and 3/8.

Since the question is about COMPLETE vases of 8 flowers, that means the answer is 165, and we don't count the 3 remaining flowers.

Good job Cameron!

What is the answer need it
denis-greek [22]

Answer:

\frac{7}{10} |

Step-by-step explanation:

STEP 1:

2/3 + 7/10 = ?

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(2/3, 7/10) = 30

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(\frac{2}{3} * \frac{10}{10}) + (\frac{7}{10} * \frac{3}{3}) = ?

Complete the multiplication and the equation becomes

\frac{20}{30} + \frac{21}{30}

The two fractions now have like denominators so you can add the numerators.

Then:

\frac{20+21}{30} = \frac{41}{30}

This fraction cannot be reduced.

The fraction 41/30

is the same as

41 divided by 30

Convert to a mixed number using

long division for 41 ÷ 30 = 1R11, so

41/30 = 1 11/30

Therefore:

2/3+7/10= 1 11/30

STEP 2:

41/30 + -2/3

The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.

LCD(41/30, -2/3) = 30

Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.

(\frac{41}{30} *\frac{1}{1} ) + ( \frac{-2}{3} * \frac{10}{10} )

The two fractions now have like denominators so you can add the numerators.

Then:

\frac{41+-20}{30} = \frac{21}{30}

This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 21 and 30 using

GCF(21,30) = 3

\frac{21/3}{30/3} =\frac{7}{10}

Therefore:

\frac{41}{30} + \frac{-2}{3} =\frac{7}{10}|

madreJ [45]

It is simple, you are converting 150 of 200 into a fraction and reducing it

150/200=15/20

5 goes into 20 4 times

15/20=1/4

1/4=0.75=75%

The balcony of an apartment is 4 feet by 7 feet. On a scale drawing of the apartment, the balcony is 0.8 inch by 1.4 inches, and
-Dominant- [34]

Answer:

The actual dimensions of the kitchen are 12\ ft by 14\ ft

Step-by-step explanation:

step 1

Find the scale  of the drawing

To find the scale , remember that is equal to the ratio of  the corresponding dimension in the drawing divided by the corresponding actual dimension

so

\frac{0.8}{4}\frac{in}{ft}=0.2\frac{in}{ft}

step 2

To find the actual dimensions of the kitchen, divide the dimension in the drawing by the scale

so

2.4\ in=2.4/0.2=12\ ft

2.8\ in=2.8/0.2=14\ ft
