Kyle can wash the car in 30 minutes. Michael can wash the car in 40 minutes. Working together, can they wash the car in less than 16 minutes?​

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!

Hope I could help you! If I did, it would mean a lot of you could give braniest or even just a thanks :) If I didn't quite answer your question, please let me know and I'll try my best to assist you!

Step-by-step explanation:

The total amount the 560 members pay in 2013 will be $96,120.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The yearly enrollment expense in 2013 is $198 for every grown-up and $75 for every kid.

Adult = 440 members

Children = 120 members

Then the total amount the 560 members pay in 2013 will be given as,

Total amount = 440 x 198 + 120 x 75

Simplify the expression, then we have

Total amount = 440 x $198 + 120 x $75

Total amount = $87,120 + $9,000

Total amount = $96,120

The total amount the 560 members pay in 2013 will be $96,120.

The complete question is given below.

The annual membership fee in 2013 is $198 for each adult and $75 for each child.

Adult = 440 members

Children = 120 members

Calculate the total amount the 560 members pay in 2013.

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.

A monomial is an expression with a single term. A binomial is an expression with 2 terms.

Looking at the given question,

a. 3y is a single term. Thus, it is a monomial

b. - 9 + h. The expression has two terms. It means that it is a binomial

c. Wr + 5wr is also a binomial

d. -7agh is a monomial

e. 2 is a monomial

f. k + 12 is a binomial

Using the triangle inequality theorem,

b - a < X < a + b

Hence,

17 - 4 < x < 17 + 4

13 < x < 21

Hence, the third side lies between 13cm and 21 cm

Let b be the number of students that were in each bus, since 111 students were on the trip, 23 students rode in cars, and the rest filled 4 buses, then we can set the following equation:

Subtracting 23 from the above equation we get:

Dividing the above equation by 4 we get:

Answer: 22 students.

The required table, which represents the relationship between the total time y and the number of rides x,

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
Let,
Total time of ride a roller is directly proportional to the number of rides, x
y = kx
where k is the rate constant,
put y = 12 and x = 4
12 = 4k
k = 3

Answer:

3a² + 6ax + 5a

Explanation:

Given the following function

g(x) = 3x² - 5x

Determine g(x+a)

g(x+a) = 3(x+a)² - 5(x+a)

Expand the result

g(x+a) = 3(x² + 2ax + a²) - (5x - 5a)

g(x+a) = 3x² + 6ax + 3a² - 5x + 5a

Determine g(x + a) - g(x)

g(x + a) - g(x) = 3x² + 6ax + 3a² - 5x + 5a - (3x² - 5x)

g(x + a) - g(x) = 3x² + 6ax + 3a² - 5x + 5a - 3x² + 5x

Collect the like terms

g(x + a) - g(x) = 3x² - 3x² - 5x + 5x + 6ax + 3a² + + 5a

g(x + a) - g(x) = 6ax + 3a² + 5a

g(x + a) - g(x) = 3a² + 6ax + 5a

Hence the required result for the function g(x + a) - g(x) is 3a² + 6ax + 5a

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

The required solution of the linear equation is x = 6.

What is linear equation?

A linear equation is a first-order (linear) term plus a constant in the algebraic form y=mx+b, where m is the slope and b is the y-intercept. Sometimes, the aforementioned is referred to as a "linear equation of two variables," where x and y are the variables.

Given [tex]\frac{3x}{2} - \frac{2x}{3}=5[/tex]

[tex]\frac{3x}{2} - \frac{2x}{3} = 5\\ \Rightarrow \frac{9x-4x}{6} = 5\\ \Rightarrow \frac{5x}{6} = 5\\\Rightarrow 5x = 30\\\Rightarrow x = 6[/tex]

Step-by-step explanation:

The angle at the circumference in a semicircle is a right angle.

Therefore, if m∠MTN = m∠SQO then:

Angles around a point sum to 360°.

As 90° is one quarter of 360°, the measure of arc MN is one quarter of the circumference of circle T.

The circumference of a circle is 2πr, where r is the radius.

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

By midpoint formula, coordinates of point A

[tex]x = \frac{0 + 2a}{2} =a , y = \frac{0+2b}{2} = b[/tex]

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

(2c,d) = coordinate of point C

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)
