Answer:

The answers are D and then B.

Step-by-step explanation:

The first question asks which team has the youngest members on average. This is easily answered because the "mean" is simply the average of all the ages. Therefore the youngest "mean" age will also have the youngest members on average.

The second question asks what team has the most variability in ages. Range is the difference between the highest and lowest number. Therefore the team with the highest range should, logically, also have the most variability.

[tex]y=-3x-14[/tex] is a function as it has:

Linear equation in slope-intercept form:  [tex]y=mx+b[/tex]

where:

Therefore, for equation [tex]y=-3x-14[/tex]

So as the equation is a linear equation, its graph is a straight line.

Therefore, the only statement that is NOT true is D as the y-intercept is -14 (not 14).

Step-by-step explanation:

you could not find the formula ?

the volume of a cylinder is ground area × height.

and the ground area is a circle.

so, in total, we have

pi×r²×h

r being the radius (half the diameter), h being the height.

therefore, the volume of the given cylinder is

pi×(6/2)²×7 = pi×3²×7 = pi×63 = 197.9203372... mm³

True

Step-by-step explanation:

Whole numbers are 'counting numbers', they don't include decimals. (ex. 1, 2, 3) Integers are non-decimal numbers and they can be negative too. (ex. -5, 0, 4). Since whole numbers are non-decimal numbers that are greater than or equal to 1, they are all integers. So this statement is False.

Rationals numbers include all numbers that are not infinite decimals. They can be fractions as long as they are not infinite and since whole numbers cannot be fractions, this statement is True.

As with the previous statement, rational numbers can be fractions and integers cannot be fractions. So, not all rational numbers are integers so this statement is False.

Rational numbers are all numbers that are not infinite decimals, so, that includes whole numbers. This statement is also True.

Therefore, he sold 28 cups of lemonade

Bao sold 28 cups and spend $2.5 on 50 cups.

A word problem in math is a math question written as one sentence or more that requires children to apply their math knowledge to a 'real-life' scenario.

Given that, Bao is selling lemonade at $0.35 per cup.

We need to determine, number of cups he sold if he earned $9.80,

And,

Bao bought 50 paper cups for $0.50 each, how much he spent on them,

1) Let he sold x cups,

So,

0.35x = 9.8

x = 28

Therefore, he sold 28 cups.

2) Since, one cup is for $0.05 therefore,

50 cups = 50 x 0.05
= $2.5

Therefore, cost of 50 cups is $2.54

The surface area of the triangular prism is:  840 in.²

Lateral area of a triangular prism (AL) = (a+b+c)h

Surface area of a triangular prism (SA) = (Perimeter of the base × Length of the prism) + (2 × Base Area) = (S1 + S2+ S3)L + bh

a. Lateral area of a triangular prism:

Lateral area of triangular prism (AL) = (8 + 15 + 17)18 = 720 in.²

The connection between the lengths and angles of a triangular shape is the subject of trigonometry.

A unit circle is shown.

A radius with length 1 forms angle θ in the first quadrant.

Then the sin θ is equal to the negative one. Then the value of the θ will be

sin θ = -1

Then it can be written as

θ = sin⁻¹ (-1)

θ = 3π / 2

Thus, the correct option is C.

Answer: 338 boys

1) Formulate an equation

The total students at Byrnade Junior High School is 464. Let girls equal x. If girls equal x and there are 212 more boys than girls, then boys should equal 212 + x. (212 + x) and x equal 464. Therefore, our equation would be (212 + x) + x = 464.

2) Isolate the variable

Simplify the equation to 212 + 2x = 464. Subtrac 212 on both sides to get 2x = 252. Divide 2 on both sides to get x = 126.

3) Plug the variable

Because x = 126, we can plug 126 into (212 + x) + x = 464 to get (212 + 126) + 126 = 464. We need to primarily focus on (212 + 126), because the question is asking for how many boys are there. 212 + 126 = 338. So, your answer should be 338 boys.

Step-by-step explanation:

ascending is smallest to largest

From the extrem left of a.number line to the right

Answer:

-2.6, -0.4, 0, 0.8, 1.2

Step-by-step explanation:

Ascending order is simply the smallest number to the largest number. The smallest numbers in this set are the negative ones, and -2.6 is a smaller value than -0.4.

So far our set looks like the following:

-2.6, -0.4

Next is 0, since 0.8 and 1.2 both come after 0. After 0 would be 0.8, and 1.2 would be the largest number.

Here is the set of numbers in ascending order:

-2.6, -0.4, 0, 0.8, 1.2

Answer:

C) $560

Step-by-step explanation:

Suppose that: r=price of red bike ,  b=price of blue , g=price of green.

Given: r=(2/3)b   g=(5/4)b  g=210+b  

Solution:

(5/4)b=210+b                   (g=g)

(5/4)b-b=210                   (take b as common factor)

b((5/4)-1)=210                  

b(0.25)=210  

b=210/0.25=$840    (so the price of blue bike is 840$)

Substitute b in equation of r:

r=(2/3)b=(2/3)(840)=560

so red bike costs $560.
