Answer:

the percentage of student who failed r 14%

and their number is 84.

Answer:

False

Step-by-step explanation:

4/10's numerator (top number) and denominator (bottom number) can both be divided by 2. Therefore, when we do that, it will be equal to 2/5. 2/5 is not equal to 1/2. Therefore, the answer is false.

Answer:

10

Step-by-step explanation:

Let c = sum of ages of all children.

mean age of all children = c/15 = 7

c = 15 * 7 = 105

The sum of the ages of all children is 105.

Let b = sum of ages of the 9 boys.

mean age of boys = b/9 = 5

b = 9 * 5 = 45

The sum of the ages of the boys is 45.

The sum of the ages of the girls is c - b.

c - b = 105 - 45 = 60

The number of girls is 15 - 9 = 6

mean age of girls = (sum of ages of the girls)/(number of girls) =

= 60/6 = 10

Answer:

[tex]Volume = 2 + 3+6[/tex]

Step-by-step explanation:

Given

[tex]Length = 2[/tex]

[tex]Width = 3[/tex]

[tex]Height = 6[/tex]

See attachment for box

Required

Which does not represent volume?

The volume is calculated as:

[tex]Volume = Length * Width * Height[/tex]

This gives:

[tex]Volume = 2 * 3 * 6[/tex] ---- (b) represents volume

Multiply 2 and 3

[tex]Volume = 6 * 6[/tex] ---- (d) represents volume

The above product can be converted to addition, as:

[tex]Volume = 6 + 6 + 6 + 6 + 6 + 6[/tex] ---- (a) represents volume

Hence:

[tex]Volume = 2 + 3+6[/tex] --- does npot represent volume

Answer: 0.001

Step-by-step explanation:

Given

The lock has 3 dials, each with the number 0 through 9.

The first place can be filled in 10 ways and the probability of selecting number '4' out of the 10 is  [tex]\frac{1}{10}[/tex]

Similarly for selecting '3' and '9' is also [tex]\frac{1}{10}[/tex]

Therefore the probability of getting a combination of 4-3-9 is

[tex]\Rightarrow P=\dfrac{1}{10}\times \dfrac{1}{10}\times\dfrac{1}{10}\\\\\Rightarrow P=\dfrac{1}{1000}\\\\\Rightarrow P=0.001[/tex]

Answer:

In a right triangle two of these are merged into the same square, so there are only two distinct inscribed squares. However, an obtuse triangle has only one inscribed square, one of whose sides coincides with part of the longest side of the triangle.

Answer: 1200

Step-by-step explanation:

x is the number of boy

The number of boys is twice the number of girls: [tex]\frac{1}{2} x[/tex]

Total is 3600 students: x + [tex]\frac{1}{2}x[/tex]= 3600 → x = 2400

Therefore, the number of girls is: 2400/2= 1200

Answer: There are 2400 boys and 1200 girls

Step-by-step explanation:

x represents girls

2x represents boys

________________________

x+2x=3600

3x =3600

x=3600/3

x =1200

Number of girls = 1200

1200 * 2 = 2400

Answer:

x intercept: 15/8 and yintercerpt is 3/2

Step-by-step explanation:

to find y intercept you have to put equation in standard form.

10y=-8x+15

y=--4/5x+3/2

x intercept is when y=0, so we plug in 0

0=-4/5x+3/2

4/5x=3/2

x=15/8

Answer:

[tex]a) A\simeq17204.28[/tex]

[tex]b) A\simeq29598.74[/tex]

[tex]c)A\simeq50922.51[/tex]

Step-by-step explanation:

The amount formula in compound interest is:

[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]

where:

P = principal amount

r = annual interest

n = number of compounding periods

t = number of years

We already know that:

P = $10000

[tex]r = 11\% = \frac{11\%}{100\%}=0.11[/tex]

n = 4 (quarterly in a year)

a ) t = 5 years

[tex]A=10000(1+\frac{0.11}{4} )^{(4)(5)}\\\\A=10000(1+\frac{0.11}{4} )^{20}\\\\A=17204.28431\\\\A\simeq17204.28[/tex]

b) t = 10 years

[tex]A=10000(1+\frac{0.11}{4} )^{(4)(10)}\\\\A=10000(1+\frac{0.11}{4} )^{40}\\\\A=29598.73987\\\\A\simeq29598.74[/tex]

c) t = 15 years

[tex]A=10000(1+\frac{0.11}{4} )^{(4)(15)}\\\\A=10000(1+\frac{0.11}{4} )^{60}\\\\A=50922.51361\\\\A\simeq50922.51[/tex]

Answer:

Solution given;

principal [p]=$10000

rate[r]=11%

time[t]= 5 years

we have

compound amount quarterly =P(1+r/400)^4t

=$10000(1+11/400)^4×5=$17204.28431

Answer:

100-16π ft2

Step-by-step explanation

Answer:

100-16π ft2

Step-by-step explanation:

Answer:

a = 81.5

b = 98.5

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

a = x-3

b = x+14

In supplementary angles , the formula are as follows,

a + b = 180

By putting the value, we get

x - 3 + x + 14 = 180

2x + 11 = 180

2x = 180 - 11

2x = 169

x = 169 ÷ 2

x = 84.5

So, a = 84.5 - 3

= 81.5

b = 84.5 + 14

= 98.5

Answer:

The solution is : cost of driving per mile is $0.42.

Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.

here, we have,

Given:

Luisa Díaz drove her vehicle about 7,200 miles last year.

Total fixed cost = $1,058.40

Total variable cost = $1965.60

Question asked:

How much did it cost per mile ?

Solution:

Total cost of driving 7200 miles = Total fixed cost + Total variable cost

                                                    = $1,058.40 + $1965.60

                                                    = $3024

By unitary method:

Cost of driving 7200 miles = $3024

Cost of driving 1 mile = $3024  7200

                                  = $0.42

Thus, cost of driving per mile is $0.42

Answer: 4√2

Step-by-step explanation:

The triangle is a special right triangle. Using this, you know that the legs of the triangle are 1 and 1 as the 45, 45, 90 triangle has the sides of 1, 1 and √2. That being said,

4 x 1 = 4 - This is one of your sides

4 x 1 = 4 - This is your other side.

4 x √2 = 4√2 = This your your hypotenuse or your x.

My teacher played me this song to help me remember 45, 45, 90 and 30, 60, 90 triangles. Look up "45 45 90 30 60 90 song" and look for the channel, "Scalar Learning"

Answer:

960

Step-by-step explanation:

First of all we can find the volume of the whole box:

8×12×10=960

then find the area of the blocks:

1×1×1=1

Finally, we divide them to find how many fit in to the box:

960÷1=960

So 960 of the blocks will fit into the box.
