Answer: 4800
If 90% are, then the remaining 10% aren’t. If 10% equals 480, 100% would be 4800. This can be found by multiplying both 10% and 480 by 10.

Answers

9514 1404 393

Answer:

  63

Step-by-step explanation:

The number of seats in a row will give an arithmetic sequence:

  6, 9, 12, 15, ...

The first term is 6; the common difference is 3. The general term is ...

  an = a1 +d(n -1) . . . . . . n-th term of sequence with first term a1, difference d

The 20th term of the sequence is ...

  a20 = 6 +3(20 -1) = 6 +57 = 63

There would be 63 seats on the 20th row.

The length of a rectangle is 5 more than twice the width. Which equation could represent the area of the rectangle in terms of the width?

Answers

Answer:

l=5+2w

Step-by-step explanation:

Since the length is twice the width plus 5, the equation would look like :

l=5+2w

A=lw

w=width

2w+5=length

42=w(2w+5)

42=2w2+5w

2w2+5w-42=0

use the quadratic equation

(-5+√25+336)/4

(-5+√361)/4

(-5+19)/4

14/4=3.5

w=3.5 m

2w+5=12 m

At Crescent High School, 108 students plan on going to an in-state college and 63 students plan on going to an out-of-state college. What is the ratio of students planning on going to an in-state college to students planning on going to an out-of-state college?
A.
12:7
B.
108:1
C.
7:12
D.
1:108

Answers

Answer:  Choice A)  12:7

Explanation:

The ratio we want to find can be thought of in the form in:out

We list the number of "in-state" people first followed by the "out-of-state" people next. A colon separates the two values. So we have the initial ratio of 108:63

Divide both parts by the GCF 9

108/9 = 1263/9 = 7

The ratio 108:63 fully reduces to 12:7 meaning there are 12 in-state students for every 7 out-of-state students. The order is important because 7:12 would be incorrect and imply we had 7 in-state vs 12 out-of-state.

6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange. 2 limes cost the same as 1 lemon. How many limes cost the same as 1 banana?  ​

Answers

6 bananas(b) =4 oranges(o)

3 lemons(l) = 1 orange (o)

3x4 =12 so that lemons equal bananas we combine the equal factor of oranges

12 (l) = 1(b)

1 lemon (1) = 2 limes(li)

1 banana(b) = 12 lemons(l)

12(l) x 2limes so that we get the amount of limes per banana since 2 limes for every 1 lemon

1 banana = 12 lemons = 24 limes

If 6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange, one lime costs the same as half of one banana.

Let's assume the cost of one banana is represented by "B" and the cost of one orange is represented by "O". Based on the given information:

6 bananas cost the same as 4 oranges: 6B = 4O

3 lemons cost the same as 1 orange: 3L = 1O

2 limes cost the same as 1 lemon: 2L = 1O

Now, we need to find the cost of one lime in terms of bananas:

From equation 3, we can rewrite it as: L = (1/2)O

Substitute the value of O from equation 2 into the above equation: L = (1/2) * 3L

Now, we have the cost of one lime in terms of lemons. From equation 2, we know 3 lemons cost the same as 1 orange, so we can rewrite it as: L = (1/2) * (1/3)O

Now, substitute the value of O from equation 1 into the above equation: L = (1/2) * (1/3) * 6B

L = (1/2)B

Therefore, one lime costs the same as half of one banana.

Which equation, in slope-intercept form, matches the equation shown?

Question 4 options:


y=47x−4


y=56x+1


y=−56x−4


y=−47x+1


Please help!

Answers

Answer: i think it is y=−56x−4

Step-by-step explanation:

The equation in the slope intercept form which passes through the points ( 0, -4 ) and ( 6 , 9 ) is y = (-5 / 6)x - 4.

The correct answer is Option C.

Given data:

To find the equation of a line in slope-intercept form (y = mx + b) that passes through the points (0, -4) and (6, -9), we need to determine the slope (m) and the y-intercept (b).

First, calculate the slope (m):

m = (change in y) / (change in x)

m = (-9 - (-4)) / (6 - 0)

m = (-9 + 4) / 6

m = -5 / 6

Now that we have the slope, we can use one of the given points (let's use (0, -4)) to solve for the y-intercept (b):

-4 = (-5 / 6) * 0 + b

-4 = b

So, the y-intercept (b) is -4.

Now, we can write the equation of the line in slope-intercept form:

y = (-5 / 6)x - 4

Hence, the equation of the line is y = (-5 / 6)x - 4.

d. n=
1

Answers

Answer:

Option D)  [tex]\huge\sf{n\:=\:\frac{(T\:-\:15)}{c}}[/tex]

Step-by-step explanation:

Given the equation, T = 15 + c × n, where:

T = represents the total monthly gym cost

c =  represents the additional charge for a group class, and

n = represents the number of group classes attended

Solution:

In order to determine which equation can be used to find the number of group classes a customer attended, if there are given values for c and T, we must isolate the variable, n  algebraically.

The first step is to subtract 15 from both sides:

T = 15 + c × n

T - 15 = 15 - 15 + c × n

T - 15 = c × n

Next, divide both sides by c to isolate n :

[tex]\huge\mathsf{\frac{({T\:-\:15})}{c}\:=\:\frac{{c\:\times\:n}}{c}}[/tex]

[tex]\huge\sf{n\:=\:\frac{(T\:-\:15)}{c}}[/tex]

Therefore, the correct answer is Option D) [tex]\huge\sf{n\:=\:\frac{(T\:-\:15)}{c}}[/tex].
