Solve the equation. 5/7p - 2/7p + 12 = 6

Answer:

11 years

Step-by-step explanation:

t=time

1700+50t=600+150t

The reason we have this equation is because they both have the same time and based on the initial numbers that they have equating the two will give you the exact year and number of students of both school.

Answer:

50%

Step-by-step explanation:

There are a total of 5 + 5 = 10 socks

Knee high socks = 5

=> 5/10 = the probability of getting knee high socks

=> 1/2

=> 50%

Answer:

1/2

Step-by-step explanation:

5 pairs of knee high socks and 5 pairs of crew socks= 10 pairs of socks

P ( knee high) = number of knee high/ total

                       = 5/10 = 1/2

I think that the answer is 21.2 .I can't say it with confidence but still maybe it will help you

Answer:

A. -4

Step-by-step explanation:

F(-1) means we must plug the number "-1" in for each x.

F(x) = x^2 + 3x - 2

F(-1) = (-1)^2 + 3(-1) - 2

= 1 - 3 - 2

= -4

Answer:

3x+4=72-x (congruent triangle side are equal)

3x+x=72-4

4x=68

X=68/4

therefore,X=17 ans

Answer:

63 dimes

Step-by-step explanation:

Set up a system of equations where d is the number of dimes and q is the number of quarters:

d + q = 106

0.1d + 0.25q = 17.05

Solve by elimination by multiplying the top equation by -0.25 to eliminate q:

-0.25d - 0.25q = -26.5

0.1d + 0.25q = 17.05

Add together and solve for d:

-0.15d = -9.45

d = 63

So, there were 63 dimes in the piggy bank

Answer: 0.001 kilometer in 1 meter

Step-by-step explanation:

1 kilometer = 1000 meter

so there are 0.001 kilometer in 1 meter

The third quartile, or the value at which 75% of all days the stock is below, is $14.3325.

Used the formula that states,

the range of the distribution by subtracting the minimum value from the maximum value:

Range = Max value - Min value = $15.17 - $11.82 = $3.35

Given that the stock value follows a uniform distribution from $11.82 to $15.17.

Hence,

Range = $15.17 - $11.82

= $3.35

Now, the uniform distribution is symmetric, and the median (50th percentile) is the midpoint of the range,

Median = (Min value + Max value) / 2

= ($11.82 + $15.17) / 2

= $13.495

Hence, the third quartile (75th percentile);

75th percentile = Median + (0.25 × Range)

= $13.495 + (0.25 × $3.35)

= $13.495 + $0.8375

= $14.3325

Pascal's triangle is a way of organizing the coefficients in the binomial expansion, [tex](a+b)^n[/tex]:

n = 0   =>  1

n = 1    =>  1   1

n = 2   =>  1   2   1

n = 3   =>  1   3   3   1

n = 4   =>  1   4   6   4   1

and so on, where each row starts and ends with a 1, and the numbers in the middle are obtained by adding together the two numbers directly above and to the left. These coefficients are then mulitplied by descending powers of a and descending powers of b (or vice versa, because the pattern is symmetric), starting with 0 and going up to n.

In this case, we have

[tex](x+4)^3=1\cdot x^3\cdot4^0+3\cdot x^2\cdot4^1+3\cdot x^1\cdot4^2+1\cdot x^0\cdot4^3[/tex]

Notice how the powers of x and 4 always sum to n = 3.

Simplifying, we get

[tex](x+4)^3=x^3+12x^2+48x+64[/tex]

so that

a = 1

b = 3

c = 12

d = 2

e = 48

[tex]55 \degree = \frac{1}{2} \bigg \{(100 \degree + 35 \degree) - x \bigg \} \\ 55 \degree \times 2 = 135 \degree - x \\ 110 \degree = 135 \degree - x \\ x = 135 \degree - 110 \degree \\ \huge \red{ \boxed{ x = 25 \degree}}[/tex]

Start by finding the slope of the line.

m = y2 - y1 / x2 - x1

m = 5 - 2/1 - 0 ⇒ 3/1 ⇒ 3.

So the slope of the line is 3.

This can be used with either one of our two points

to write the equation of the line in point-slope form.

So let's go with the point (0, 2).

Point-slope form is written y - y1 = m(x - x1).

Since we are using the point (0, 2), y - y1 would be y - 2.

"m" would be 3 and x1 would be 0.

So we have y - 2 = 3(x - 0).

Answer:

The bowl's diameter is 35.8 cm

Step-by-step explanation:

Recall that 1 liter = 1000 cubic cm ad have in mind that in order to get a diameter in cm, we would need to write the volume of the bowl in cubic cm.

if 6 liters is 1/4 of the bowl, then 4 times 6 liters must fill the bowl. That is: the volume of the sphere is 24 liters.

24 liters in cubic cm is: 24000 cubic cm

now, we need to use the formula for the volume of a sphere of radius R:

[tex]Vol=\frac{4}{3} \pi\,R^3\\24000=\frac{4}{3} \pi\,R^3\\R^3=\frac{24000\,(3)}{4\,\pi} \\R=\sqrt[3]{\frac{24000\,(3)}{4\,\pi} } \\R\approx 17.894\,\,cm[/tex]

therefore, the diameter of the bowl is twice this radius value:

[tex]Diameter\approx 17.894\,* 2=35.788\,\,cm[/tex]

this value rounded to 3 significant figures is: 35.8 cm

Answer:

Step-by-step explanation:

We observe that the values in the top row are sequential, and that the values in the bottom row have a common difference of 32. That means the sequence is an arithmetic sequence.

__

The values in the table form an arithmetic sequence. The term values are shown in the bottom row, and the term numbers are shown in the top row. This sequence is associated with a linear function. The domain of the function is the set of time values: greater than or equal to zero.

__

Comment on the function

This function seems to be the linear function ...

  distance = 32×time - 16

It seems a little odd that the distance associated with time zero is negative. We usually think of distance as a positive value, whereas displacement can be a signed value.

As a rule, time is measured as positive from some reference point (the start of motion, for example). Here, we have no reason to believe that the function is intended to be defined for negative time values.

Answer: 1.6 hours.

Step-by-step explanation:

Ok, the speed of the bats is 99mph.

Here we can think this situation as a circle where the radius is growing at a speed of 99mph.

We assume that the initial radius is r = 0, and we can write the equation of the radius as a linear equation that depends on the time t.

r(t) = 99mi/h*t

First, let's find the radius that we need:

The area of a circle is:

A = ´pi*r^2

If we want A = 80,000 mi^2 we have:

80,000 mi^2 = 3.14*r^2

r = √(80,000 mi^2/3.14) = 159.6 mi

So the radius must be 159.6 miles.

Now, we know that the speed at which the radius increases is 99miles per hour, and we also know that:

Distance = Speed*Time.

in this case:

Distance = 159.6 mi

Speed = 99mi/h

Time = is the thing we want to find.

159.6mi = 99mi/h*T

T = 159.6mi/99mi/h = 1.6 hours.

Answer:

51.96 mm² approximately

Step-by-step explanation:

the first thing you should know is that the area of a rectangle is base*height sin of (

the included angle i.e

Arectangle= bh sin90° since all angles of a rectangle are equal then the included angle is 90°

Arectangle= bh sin90° since sin90 is 1 we simply use the equation bh because multiplying bh by one is bh. bearing this in mind , the area of the parallelogram can be calculated as:

Aparallelogram= bh sin of sin of the included angle

Aparallelogram= bh sin of sin of the included angle Aparallelogram=6mm*10mm sin 60°

Aparallelogram= bh sin of sin of the included angle Aparallelogram=6mm*10mm sin 60°Aparallelogram=60mm² * 0.866

Aparallelogram= bh sin of sin of the included angle Aparallelogram=6mm*10mm sin 60°Aparallelogram=60mm² * 0.866Aparallelogram=51.96 mm² approximately
