Answer:

P(red) = .3

P(yellow) = .3

75 cubes in the box

Step-by-step explanation:

The probability has to add to 1

Since the number of red cubes equals the number of yellow cubes the probability has to be the same

.4 + x+x = 1

.4 +2x = 1

2x = 1-.4

2x = .6

Divide by 2

x = .6/2

x = .3

P(red) = .3

P(yellow) = .3

We know that

P(blue) = .4 = number of blue cubes/ total number of cubes

                 .4 = 30/total

                  total = 30/.4

                   total = 75

Answer:

B

Step-by-step explanation:

To calculate the area of this triangle we can use the Heron’s formula

Mathematically we have the Heron’s formula as;

A = √s(s-a)(s-b)(s-c)

where s = (a + b + c)/2

Thus, s = (15 + 12+ 10)/2 = 18.5

a = 15, b = 12 and c = 10

Plugging these values into the equation, we have

√18.5(18.5-15)(18.5-12)(18.5-10)

= √18.5(3.5)(6.5)(8.5)

= √ 3,577.4375

A = 59.8116

which is approximately 59.8 square units

Answer:

we are going to use BODMAS

7.(2+18) -14

is also 7×(2+18) -14

since B representing bracket comes first,

we add the numbers in the bracket.

2+18=20

7×(20) -14

then M representing multiplication comes next do we multiply.

7×20=140

140-14=126

that's it!

Answer:

3x^2 - 15 = 0

-x^2 + 14 = 0

-2x^2 + 4x - 5 = 0

Step-by-step explanation:

3x^2 = 15

3x^2 - 15 = 0

-x^2 = -14

-x^2 + 14 = 0

4x - 2x^2 = 5

-2x^2 + 4x - 5 = 0

Step-by-step explanation:

The offer is 25% sale on cupcakes

Single cake costs = 9

25% = 0.25

After discount the price of cake = 9 x 0.25 = 2.25

Answer:

The ball is 7 feet above the ground 2 seconds after it is thrown.

Step-by-step explanation:

As per the given statement, we are given a graph of function [tex]f(x)[/tex] where 'x' is time (in seconds) in the current scenario.

Time is plotted on x axis and height of football is plotted on y axis.

[tex]f(x)[/tex] is the height of football according to change in time.

Following are the few things that can be observed from the given curve:

1. Initial Height of football is ~4.8 feet i.e. at 0 seconds of time.

2. Football reaches a maximum height of ~7.2 feet at 1.5 seconds.

3. After 1.5 seconds, the height of football starts decreasing.

Here f(2) means, the height of ball at 2 seconds of time.

It is clearly visible from the given graph that height is 7 feet at 2 seconds.

Please refer to the attached answer image. Height at 2 seconds is marked as point P.

Hence, The ball is 7 feet above the ground 2 seconds after it is thrown.

The range is the largest number minus the smallest number

100 -20

80

Answer:

164 people

Step-by-step explanation:

100% represents the 150 people who attended last year.

this year , there is an increase of 9% , which will make the total percentage to be 109%.

if ; 100% = 150 people

     109% = ?

cross multiply to get 163.5 the round off to get 164

Step-by-step explanation:

375 days a year, 7 days a week

375/7

53.57 weeks in a year

24 paychecks of 863.50 = 46257.695$ a year

46257.695/53.57 = 863.5

Answer:

Step-by-step explanation:

(i) Area of ABCD = (base1+base2)*height/2

                           = (6+12)*4/2 = 36 cm2

(ii) Volume = Area of ABCD * length = 36 * 25 = 900 cm3

(iii) Total SA = Area of ABCD *2 + 25*5*2 + 6*25 + 12*25

                    = 72                         + 250      + 150   + 300

                    = 772cm2

Answer:

RC1.  5

RC2. 8

RC3. a

RC4. 3

Step-by-step explanation:

So basically what you need to start with is the fact that the second triangle is 2 times larger than the first.

so,

8 = 8

C = 10

A = 6

---------------------------------------------------------------------

the next important part is that the opposite sides of the fraction, when multiplied are equal to each other.

( for example 1/2 = 2/4, because 1*4 = 4 and 2*2 = 4)

RC1. a/3 = C/_

substitute

6/3 = 10/_

3 * 10 = 30

6 * _ =30

30/6 = 5.

Rc2. 4c = 5_

4*10 = 5*_

40/5 = 8

RC3. 3c = 5*_

3*10 = 5*_

30/5 = 6

RC4. 4a = 8*_

4 * 6 = 8*_

24/8 = 3

good luck with your schoolwork/homework!

Answer:

x=14

Step-by-step explanation:

4x-y=21

y=3x-7

Substitute the second equation in for y in the first

4x - (3x-7) = 21

Distribute the minus sign

4x -3x +7 = 21

x +7 = 21

Subtract 7 from each side

x+7-7=21-7

x=14

Answer:   x=14 is right answer

4x-y=21 =

Slope = 4

x-intercept = 21/4 = 5.25000

 y-intercept = 21/-1 = -21.00000

y=3x-7 =

 Slope = 6.000/2.000 = 3.000

 x-intercept = 7/3 = 2.33333

 y-intercept = -7/1 = -7.00000

Answer:

15/16

Step-by-step explanation:

The probability of not getting all heads is

1 - P(all heads)

P (all heads) =P(heads) *  P(heads)* P(heads) * P(heads)

                      1/2* 1/2 * 1/2 * 1/2 = 1/16

1 - 1//16 = 15/16

Answer:

the answer is 1

Step-by-step explanation:

anything to the 0th power is 1

Answer:

The answer you are looking for is 1

Step-by-step explanation:

Any number raised to the power of one equals the number itself. Any number raised to the power of zero, except zero, equals one. This multiplication rule tells us that we can simply add the exponents when multiplying two powers with the same base.

Answer:

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

She sold:

1/3 on Tuesday.

5/12 on Wednesday.

What fraction of blue shirts did she sell on Tuesday and Wednesday?

Sum of fractions.

The lesser common multiplier between 3 and 12, which is 12.

So

[tex]\frac{1}{3} + \frac{5}{12} = \frac{\frac{12*1}{3} + \frac{12*5}{12}}{12} = \frac{4 + 5}{12} = \frac{9}{12} = \frac{3}{4}[/tex]

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Answer:

21

Step-by-step explanation:

Answer:

37 years

Step-by-step explanation:

If the mean age of 5 people in that room was 25 years,

∴ Sum₍₅₎= (25×5)years

              = 125 years

When a person enters that room, the mean age was now 27.

∴ Sum₍₆₎=(27×6) years

              = 162 years

∴ The age of the person who entered the room = Sum₍₆₎ - Sum₍₅₎

                                                                                 = (162-125) years

                                                                                 = 37 years

∴ The age of the person who entered the room is 37 years.
