Answer:

We expect 900 students to borrow library books

Step-by-step explanation:

Proportions

If two variables are proportional, then one of them can be obtained as the other times a fixed number.

If x and y are proportional, then:

y=k.x

Where k is the constant of proportionality

The value of k can be obtained by dividing y/x.

That division, also called ratio gives us the proportion to be applied to future calculations.

In Sophia's class, 3 out of 4 students borrowed library books.

This gives us a proportion ratio of 3/4.

If we apply that same proportion to the rest of the Liberty Center Middle School, with 1,200 students, then, we expect to have

3 / 4 * 1200 = 900 students borrowing library books.

Answer:

B. 1.25n = c

Step-by-step explanation:

Take one of the points. 20 and $16.

It will look like this 20/16n = c

20/16 = 1.25

1.25n = c

Hope this helps ya! Keep smiling!

The required equation is 1.25n = c where the cost is c and n-brownies for Caleb's pricing. which is the correct answer would be an option (B).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

Caleb and Ynez, two pals, are each selling brownies for a class fundraiser. They plan to publicize the price of a particular amount of brownies in two distinct ways.

We have been given that the graph

According to the given graph, we take two points 20 and $16.

Let the cost, c, and n-brownies for Caleb's pricing.

It will examine like this 20/16n = c

20/16 = 1.25

1.25n = c

Therefore, the required equation is 1.25n = c

Answer:

22/3 feet

Step-by-step explanation:

In Lixue's garden, the green pepper plants grew 5 inches in 3/4 month.

We need to find how many feet can they grow in one month.

Let 5 inches = 5 1/2 feet

It means,

The growth in 3/4 month = 5 inches = 11/2 feet

Growth in 1 month = [tex]\dfrac{\dfrac{11}{2}}{\dfrac{3}{4}}=\dfrac{22}{3}[/tex] feet

So, it will grow 22/3 feet in a month.

Step-by-step explanation:

Answer: y - 9 = (-3/2) (x - (-4))

Step-by-step explanation:

We can use the formula y-y1 = m(x-x1)

Where (x1,y1) are (-4, 9) and m = -3/2. Plug in the values and we get

y - 9 = (-3/2) (x - (-4))

Step-by-step explanation:

Answer: The bell rins at 8:19 AM, and the distance between Jimmy's house and the school is 960 meters.

Step-by-step explanation:

Let's define the variables:

T = Number of minutes after 8 AM such that the school's bell sounds.

D = Distance between jimmy's house and the school, in meters

And remember the relation:

Distance = Speed*Time.

We know that:

"If he walks at 40 meters per minute, he will reach his school 5 minutes late."

D = (T + 5)*40

"If he walks at 60 meters per minute, he will reach his school 3 minutes before the bell rings."

D = (T - 3)*60

Then we have a system of equations:

D = (T + 5)*40

D = (T - 3)*60

We can take the quotient of these two equations and get:

D/D = ((T + 5)*40 )/((T - 3)*60)

1 = (4/6)*(T + 5)/(T - 3)

Now let's solve this for T.

6/4 = (T + 5)/(T - 3)

(6/4)*T - (6/4)*3 = T + 5

(6/4)*T - T = 5 + (6/4)*3

T*(2/4) = 5 + 18/4 = 5 + 9/2

T = (4/2)*(5 + 9/2) = 19

Then the bell sounds 19 minutes after 8AM, at 8:19 AM

And with this, we can find the distance D:

D = (T + 5)*40 = (19 + 5)*40 = 960

The distance between Jimmy's house and the school is 960 meters.

Step-by-step explanation:

It wouldn't be A since 5 - 1 you would get 4 hundred not 4 tens. It wouldnt be B because 9 - 6 you would get 3 ones not 3 hundreds and 5-1 you would get 4 hundreds not 4 ones. It wouldnt be D because 9-6 would be 3 ones not 3 tens. Hope I helped ! Good luck !

Answer:

3,6

Step-by-step explanation:

Plug 2x(y) into 5x -y = 9

5x -2x = 9

Add like terms.

3x = 9

Divide both sides by 3.

x = 3

Now, in order to find y, plug 3(x) into y = 2x

y = 2(3)

y = 6

The solution of system of equation is x=3 and y=6.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y=2x .....................(1)

5x-y=9...............(2)

Now substitute the value of y in equation (2), we get

5x - 2x = 9

3x = 9

Divide both side by 3.

x= 3

and, y= 2x = 6

Answer:

the y-intercept is 15 which is the initial total depth of the snow at t=0 hours.

The rate of melting is 1.5inches per hour.  It will take 10 hours at the melting rate given of 1.5 to melt all the snow.

Step-by-step explanation:

the y-intercept is 15, and it might mean that the total depth of the snow is 15 inches.

The rate of melting is 1.5inches per hour.

At time = 0, S=15 - 1.5t = 15 - 1.5(0) = 15 inches to start

At time = 10, S=15 - 1.5t = 15 - 1.5(10) = 0 inches; meaning all snow has melted and it took 10 hours.

Answer:

a) [tex]y=\frac{28}{75}(x-1900)+47.3[/tex]

b) 86.5 years

Step-by-step explanation:

All values are rounded to 2 decimal places

a) We can find line by using y =mx+b

[tex]y=mx+b\\m=\frac{y^{2}-y^{1} }{x^{2}-x^{1}}\\m=\frac{69.7-47.3}{1960-1900} \\m=\frac{22.4}{60} \\m=\frac{28}{75}\\c=y-intercept\\y-intercept=47.3\\y=\frac{28}{75} (x-1900)+47.3[/tex]

Therefore the line of best fit is [tex]y=\frac{28}{75}(x-1900)+47.3\\[/tex]

b) We can do this by using the formula of the best fit line to estimate the life expectancy of someone born in 2005

[tex]y=\frac{28}{75}(x-1900)+47.3\\y=\frac{28}{75}(2005-1900)+47.3\\y=\frac{28}{75}\times105+47.3\\y=86.5[/tex]

Therefore the estimated life expectancy of someone born in 2005 is 86.5 years
