There are 150 children in middle school.30% of the students are 6th graders. How many 6th graders are at CPCS?

Answer:

9n=63

n=7

Step-by-step explanation:

Answer:

Replace the word "is" with an equals sign. Replace the word "product" with a multiplication sign. Replace the words "a number" with the variable n, to represent the unknown value. The equation is 63 = 9n.

Step-by-step explanation:

correct on edge

Answer: Yes

Step-by-step explanation:

To find if (-6,22) is a solution to y=-3x+4, we can directly plug in the coordinates.

22=-3(-6)+4       [multiply]

22=18+4            [add]

22=22

Since 22=22, we know that (-6,22) is a solution to y=-3x+4.

Answer: £516

Step-by-step explanation:

7.5 increase = 100 + 7.5 = 107.5

107.5/100 = 1.075 (multiplier)

480 x 1.075 = 516

Answer:

Raisins = 25 kg

Nuts = 15 kg

Step-by-step explanation:

Given that:

Kilograms of snack to be made = 40 kg

Price per kg would be $4.75kg.

Price of 40 kg would be = 4.75 * 40 = $190

Let,

x be the kilograms of raisins

y be the kilograms of nuts

According to given statement;

x+y=40        Eqn 1

4.00x+6.00y=190      Eqn 2

Multiplying Eqn 1 by 4

4(x+y=40)

4x+4y=160    Eqn 3

Subtracting Eqn 3 from Eqn 2

(4x+6y)-(4x+4y)=190-160

4x+6y-4x-4y=30

2y=30

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{30}{2}\\y=15[/tex]

Putting y=15 in Eqn 1

x+15=40

x=40-15

x=25

Hence,

Raisins = 25 kg

Nuts = 15 kg

Answer:

the answer is

raisins= 25 kg

nuts= 15 kg

Answer:

log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

Step-by-step explanation:

for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477

and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219

Step-by-step explanation:   Using Properties of Logs

logb(x/y) = logbx - logby.

Furthermore

log5 (4/7)= log5 (4)- log5 (7)

Solve log 5 (4) and log 5 (7)  with the base change of the logarithm

log 5 4 = log 4 / log 5

Use the calculator (DESMOS):  log 5 4 =0.8613531161

log 5 7 = log 7 / log 5

log 5 7 =1.2090619551

Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839

Answer:

Table M does not represent a linear function, however table N does.

Step-by-step explanation:

In table M, y does not have a constant rate of change in relation to x

(in table M, the x value of -3 is repeated and the y value is not constant with the x value of -3)

In table N, the y value has a constant rate of change of 6 corresponding to each x value.

Answer:

2/11

Step-by-step explanation:

Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"

4 2/5 + k = -3 2/11

I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.

4 2/5 + k = -3 -2/11

k = - 3 - 4 - 2/5 - 2/11

k= - 7 -2/5 -2/11

Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.

k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)

k = - 385/55 - 22/55 -10/55

k = - (385 +22+10)/55

k = - 417/55

Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.

btw correct me if i am wrong

Answer:

[tex] k = - 1 \frac{12}{55} [/tex]

Step-by-step explanation:

[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]

Given:

The graph of a line.

To find:

The y-intercept of the line.

Solution:

y-intercept of a line is the point at which the line intersect the y-axis.

We have, graph of the line.

From the given graph it is clear that the line intersect the y-axis at (0,4).

So, y-intercept is at point (0,4).

y-intercept = 4

Therefore, the y-intercept is 4.

Answer: $65

Step-by-step explanation:

The store is having a 20% off sale.

Mai buys an item and saves $13.

This means that $13 is 20% of the price of the item that Mai bought.

Assume the original price is x. Expression is:

x * 20% = 13

x = 13/20%

x = $65

Answer:

3 1/3 feets

Step-by-step explanation:

Given that:

Height of aquarium = 1 3/4 feets

Area of aquarium = 5 5/6 ft²

The length of aquarium = x

Aquarium is shaped in the form of a rectangle :

Area of a rectangle = Length * width

5 5/6 = x * 1 3/4

35/6 = 7x/4

Cross multiply :

7x * 6 = 35 * 4

42x = 140

x = 140 / 42

x = 3 14/42

x = 3 1/3 feets

Hence, Length of the back of aquarium is 3 1/3 feets
