Answer:

5 is the number

Step-by-step explanation:

2x + 12 = 22

2x+12-12 = 22-12

2x = 10

2x÷2 = 10÷2

x=5

Plug x back in the equation and check the answer.

2(5)+12 = 22

10+12 = 22

22=22

The total cost of all the items mentioned can be expressed as

12.99 + 1.19 P = C

Given : Sara needs to purchase one notebook

Also it is given that pack of pencils is represented by P

Since a notebook costs = $ 12.99

And pack of pencils cost = $ 1.19

Thus the total cost can simply be represented by adding all the above mentioned items

this means it can be written as

12.99 + 1.19 P = C where C represents the total cost { given }

$866.25

1) Gathering the data

$1575

she spent 30%

she spent 3/14

2) Let's calculate it, starting with the 30% expense. Writing a factor, we have already the value:

1575 x ( 1 -0.3)

1575 x (0.7)

1102.50

Now let's proceed with the deduction of 3/14, which can be calculated through that:

1102.5 -3/14x (1102.5)

$866.25

3) Hence, Taylor's balance was after those payments of $866.25

Rational number which does the square root of 30 fall is between 5 and 5.5.

A rational number is any number that can be expressed as a ratio (or fraction) of two integers. p/q where q is not equal to 0 is the form of a rational number, which is a sort of real number in mathematics. A rational number is any fraction with a non-zero denominator. 1/2, 1/5, 3/4, and other like numbers are a few examples of rational numbers.

Given,

25 and 36, which are the squares of 5 and 6, respectively, are the perfect squares that are most similar to 30.

Therefore, the square root of 30 will lie between 5 and 6. Additionally, the square root of 30 will be between 5 and 5.5 because it is closer to 25 than it is to 36.

Given that

We can find the measurement of angle B by getting the cosine inverse/arccos of 0.2536, which is calculated as follows

The problem requires that our answer is in the nearest tenth, hence, rounding off 75 to the nearest tenth, we get 80 degrees. Therefore, angle B has a measurement of 80 degrees.

Additional note that when computing such a problem, the calculator must be in terms of degrees, not radians.

Answer:

63 days

Explanation:

Given the total number of days in a yesr = 180 days

Percent of the time he walks to school = 35 %

Number of days he walks to school = 35% of 180

Number of days he walks to school = 0.35 * 180

Number of days he walks to school = 63 days

Hence the number of days he walked to schools is 63 days

Here,  the mid point of line joining  R(0,0) and S(2a,2b)

By midpoint formula, coordinates of point A

so

coordinate of point A is (a,b)

[tex]Also, C. is \\ the midpoint of line joining \\T (2c,2d) and V(2c,0)[/tex]

coordinate of point C is given by

[tex]x = \frac{2c+2c}{2} = 2c, y = \frac{2d+0}{2} = d[/tex]

so we have

it is given that coordinate of point B is (a+c, b+d) and coordinate of D is (c,0)

If we have points P(x1,y1)  and Q (x2,y2)

Answer:

The tank is currently 40% (40 percent) full.

Step-by-step explanation:

We can find this by dividing the current fullness (648 gal) by the full tank (1620 gal).

648 / 1620 = 0.4

0.4 = 40%

How do we know to divide 648 by 1620 and not the other way around?

We know this because that we want to know what percent of the full tank is currently full. It's something that you just need to get used to, once you do enough of these types of problems, I'm sure you'll get the hang of it!
