Answer:

Cups = 24

Plates = 48

Balloons = 12

Total = 84

Step-by-step explanation:

Serena's mom is planning her birthday party. She bought balloons, plates, and cups. Serena's mom brought twice as many plates as cups. The number of balloons Serena's mom bought was half the number of cups. If Serena's mom bought 84 items, how many of each item did she buy.

Let

c = number of cups

Serena's mom bought twice as many plates as cups.

2c = number of plates

number of balloons Serena's mom bought was half the number of cups

0.5c = the number of balloons

Total items = 84

c + 2c + 0.5c = 84

3.5c = 84

Divide both sides by 3.5

3.5c / 3.5 = 84 / 3.5

c = 24

c = number of cups = 24

2c = number of plates = 2 * 24 = 48

0.5c = the number of balloons = 0.5*24 = 12

Cups = 24

Plates = 48

Balloons = 12

Total = 84

Answer:

23.13m^2

Step-by-step explanation:

We'll use 3.14 for pi as instructed.

We can rearrange the figure to one square and 2 full circles.

Area of the square is 3m*3m = 9m^2

Area of a single full circle is pi*1.5m*1.5m = pi*2.25m^2 = 3.14*2.25m^2 = 7.065m^2

Full area = 9m^2 + 2*7.065m^2 = 9m^2 + 14.13m^2 = 23.13m^2

Answer:

23.14

Step-by-step explanation:

tto find the area of a circle itz A=πr

A=π1.5=7.07

3x3=9

7.07+7.07+9=23.14

Answer: D.

Answer:

Area of the unshaded sector = 113.4 sq units

Area of the shaded sector = 200.6 sq units

Step-by-step explanation:

First let us calculate the area of the circle

Area of the circle = πr²

radius r  = 10units

Area of the circle = π(10)²

Area of the circle = π(100)

Area of the circle = 3.14(100)

Area of the circle = 314 sq. units

Area of a sector = theta/360 * πr²

Area of the unshaded sector = 130/360 * 314

Area of the unshaded sector = 13/36 * 314

Area of the unshaded sector = 113.389 sq units

Area of the unshaded sector = 113.4 sq units

Area of the shaded sector = Area of circle - Area of the unshaded sector

Area of the shaded sector = 314 - 113.89

Area of the shaded sector = 200.6sq. units

Answer:

Lucas monthly net pay is $1758

Step-by-step explanation:

Lucas works for a salary of $2,396 per month.

His deductions include $360 of federal income tax,

$148 for Social Security,

$35 for Medicare, and

a $95 insurance premium.

Now,

2396 - 360 - 148 - 35 - 95 = 1758

Thus, Lucas monthly net pay is $1758

Answer:

= 6.1072 × 10 to the 6 power

(scientific notation)

Step-by-step explanation:

Answer:

The number 6,107,200 in scientific notation is 6.1072 x [tex]10^{6}[/tex]

Step-by-step explanation:

Answer:

because the length is 4 feet more than the width

=> the length is x + 4 (feet)

because the base has an area of 21 square feet

=> x(x + 4) = 21

<=> x² + 4x = 21

Step-by-step explanation:

Simplify

Answer:

x=3, y= -6

Step-by-step explanation:

make 4+y= -x as equation (1) and make y=2x-10 as equation (2, then you must find a third equation either from equation (1)or (2). If you choose to find equation (3) from (2) it will be y=2x-10 , then substitute equation (3) from (1) because you can't choose (2) , then it will be 4+(2x-10)= -x

the answer will be x =2

substitute x from equation (3)

y=2x-10

y=2 (2)-10

y= -6

Answer:

24/60 = 2/5

Step-by-step explanation: dont have one

Answer:

2/5, or 40%

Step-by-step explanation:

The experimental probability is not what the mathematical probability of something always is of happening, but rather the probability based on the pattern of given data in a given experiment. So rather than giving the likelihood of picking a red card on the next pick, you would instead give the "likelihood" of picking a red card based on the trend found in the given data. This would amount to 24/60 which, simplified, would be 2/5, or 40%.

I would appreciate Brainliest, but no worries.

right angle is always 90

total inside a triangle is always 180

35 + 90 = 125

180 - 125 = 55

Answer:

3,672

Step-by-step explanation:

Given the sequence 6, 9, 12...

The sequence is an arithmetic sequence

first term a = 6

common difference d = 9 - 6 = 12 - 9 = 3

number of terms n = 48

Sn = n/2[2a+(n-1)d]

Substitute the given values

S48 = 48/2[2(6)+(48-1)(3)]

S48 = 24(12+(3*47))

S48 = 24(12+141)

S48 = 24(153)

S48 = 3,672

Hence the sum of the first 48terms is 3,672
