Answer:

If there is no 48 divided by 8 then it is 8 x _ = 48.

Step-by-step explanation:

Think about it. There are 6 times more children than adults *6 x 8 = 48.

Answer:

8 x______=48

Step-by-step explanation:

In the problem, they are telling you there are 48 children and 8 adults at the library. Then, they tell you how many times more adults than children are at the library. You aren't adding, and since they are saying times more, that is a sign of multiplication. Hope this helps!

Answer:

because The perimeter of a rectangular playground can be no greater than 120 meters, The width of the playground cannot exceed 22 meters

=> the length of the playground cannot exceed: (120/2)-22= 38(meters)

Step-by-step explanation:

Answer:

f = 0.9 pounds.

Step-by-step explanation:

Let f = weight of the football.

Let b = weight of the basketball.

Given the following data;

Weight of each basketball, b = 1.37 pounds

Translating the word problem into an algebraic equation, we have;

[tex] 3f + 2b = 5.44[/tex] ..........equation 1

[tex] b = 1.37[/tex] ....................equation 2

Substituting equation 2 into equation 1, we have;

[tex] 3f + 2(1.37) = 5.44[/tex]

[tex] 3f + 2.74 = 5.44[/tex]

Rearranging the equation, we have;

[tex] 3f = 5.44 - 2.74[/tex]

[tex] 3f = 2.7[/tex]

[tex] f = \frac{2.7}{3} [/tex]

f = 0.9 pounds

Therefore, the weight of each football is 0.9 pounds.

KL= 2 K'L'

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Now,

scale factor= KL/ K'L'

2= KL/ K'L'

KL = 2  K'L'

Hence, K'L' is two times of KL.

Answer:

A)F(x)=1/(x+1)^2

Step-by-step explanation:

The rational functions which is graphed is f(x) =1/(x+1)², option A is correct.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

A relation is a function if it has only one y-value for each x-value.

Rational function is the ratio of two polynomial functions where the denominator polynomial is not equal to zero.

There are vertical asymptotes at -1.

Vertical asymptotes are present where x on the denominator is equal to 0

f(x) =1/(x+1)² is the rational function.

Hence, the  rational functions which is graphed is f(x) =1/(x+1)², option A is correct.

Answer: Kate = £102

Sanjeev = £153

Step-by-step explanation:

From the question, we are informed that for every £2 that kat collects, sanjeev collects £3. This csn be represented in a fraction as:

Kat = 2/5

Sanjeev = 3/5

The amount that each collects will be:

Kat = 2/5 × £255

= 2 × £51

= £102

Sanjeev = 3/5 × £255

= 3 × £51

= £153

Answer:

Given :

Price per folder = $2.15 .

Price per notebook = $4.60 .

The supply budget for this meeting is $150.

To Find :

Inequality represents the constraint on the number of folders f and notebooks n the office administrator can purchase.

Solution :

Let, number of folders and notebooks is f and n.

So, price of buying f and n number of folders and notebooks are :

P = 2.15f + 4.60n

Now, it is given that P ≤ $150 .

So,

2.15f + 4.60n ≤ 150

Hence, this is the required solution.

[tex]2.15f+2.5n\leq 150[/tex] inequality will represent the constraint on the number of folders f and notebooks n the office administrator can purchase.

Given information:

An office administrator will be purchasing supplies for an upcoming meeting.

Staff will purchase folders, which are $2.15 each, and notebooks, which are $4.60 each.

The supply budget for this meeting is $150.

Let f be the number of folders purchased and n  be the number of notebooks purchased.

Now, the total amount spent on the whole purchase should not be greater than $150 which is the budget of the shopping.

In the form of inequality, the given condition can be written as,

[tex]2.15f+4.6n\leq 150[/tex]

The total amount spent is less than equal to 150.

Therefore, [tex]2.15f+4.6n\leq 150[/tex] inequality will represent the constraint on the number of folders f and notebooks n the office administrator can purchase.

For a graphical representation of the inequality, see the image attached.

Answer:

6m^2+14m+24

Step-by-step explanation:

Just got the answer off od Deltamath

The sum of the expressions is 6m²+14+24

A mathematical statement having variables and numbers which related by mathematical operations is called an expression.

Given are two expressions, C = 3m²+4m+5 and D = 3m+7

We need to find 2C+2D,

2C = 2(3m²+4m+5)

= 6m²+8m+10

2D = 2(3m+7)

= 6m+14

Therefore,

2C+2D = (6m²+8m+10) + (6m+14)

= 6m²+8m+10+6m+14

= 6m²+14+24

Hence, the sum of the expressions is 6m²+14+24

Answer: 16 square units

Step-by-step explanation:

let the vertex in quadrant I be (x,y)  

then the vertex in quadratnt II is (-x,y)  

base of the rectangle = 2x  

height of the rectangle = y  

Area = xy  

= x(12 - x²)  

= -x³ + 12x  

d(area)/dx = 3x² - 12 = 0 for a maximum of area  

3x² = 12  

x² = 4  

x = ±2  

y = 12-4 = 8

So, the largest area = 2 x 8 = 16 square units
