An art shop has 80 large boxes of markers and 34 small boxes of markers in stock. Each large box contains 48 markers and each small box contains 20 markers. Which equation could be used to find n, the total number of markers in stock?

Answers

Answer: n= 80 ×48+ 34×20

Step-by-step explanation:

Given: Number of large boxes = 80

Number of small boxes = 34

Number of markers in each large box = 48

Number of markers in each small box = 20

Total markers = (Number of large boxes)x (Number of markers in each large box) + (Number of small boxes) x (Number of markers in each small box)

Total number of markers = n (given)

Then, n= 80 ×48+ 34×20

Therefore , the equation could be used to find n, the total number of markers in stock: n= 80 ×48+ 34×20

Answers

Answer:

x(x + 1)

Step-by-step explanation: This is an important way of solving quadratic equations. The first step of factorising an expression is to 'take out' any common factors which the terms have. So if you were asked to factorise x² + x, since x goes into both terms, you would write x(x + 1)

Can you find the slope-intercept equation of each line and type the correct code? Please remember to type in ALL CAPS with no spaces.

Answers

Answer:

The answer for the code is CGIA

Step-by-step explanation:

The slope- intercept of each line is

First line,

y= x+ 2

Second line,

y = 2x +2

Third line,

y= -x +1

Fourth line,

y= -2x - 2

What is slope?

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

First line,

slope intercept form

(y - 3)= 1(x-1)

y= x+ 2

Second line,

slope intercept form

(y - 2)= 2(x-0)

y = 2x +2

Third line,

slope intercept form

(y + 2)= (-1)(x - 3)

y= -x +1

Fourth line,

slope intercept form

(y + 2 )= -2(x-0)

y= -2x - 2

Step-by-step explanation:

When Dividing fractions, use the reciprocal of 3/4

7 1/2 times 4/3 equals

Answer:

10

Step-by-step explanation:

You would do something called KCF Keep, Change, and Flip.

You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.

15/6 times 4/3. 15 x 4 = 60

so I can be 60/6 but you would simplify and 6 goes into 60  10 times. so 10 is you answer

In a fish tank, 50% of the fish are clown fish, 1/3 are angel fish and the rest are goldfish. There are 33 clown fish in the fish tank. (b) How many goldfish are there in the fish tank?

Answers

Answer:

11 gold fish

Step-by-step explanation:

We are told that

In a fish tank, 50% of the fish are clown fish and there are 33 clown fish in the fish tank.

Let the total number of fishes in the tank be = x

Hence,

50% of x = 33

50/100 × x = 33

50x/100 = 33

Cross Multiplying

50x = 33 × 100

x = 33 × 100/50

x = 66 fishes

Hence, the total number of fishes in the tank = 66 fishes

1/3 are angel fish

The number of angel fishes are

1/3 × 66 fishes = 22 angel fish

•The rest are goldfish. How many goldfish are there in the fish tank?

The number of gold fish is calculated as:

Total number of fishes -( Number of clown fish + Number of angel fish)

= 66 - (33 + 22)

= 66 - 55

= 11

Therefore, the number of gold fish is 11

Step-by-step explanation:

1/33 because its 33 goldfish

Find the surface area of the prism.



The surface area is square millimeters.​

Answers

Answer:

57.1mm^2

Step-by-step explanation:

4*4=16

16/2=8mm^2 cross section

(4*3) + (4*3) + (5.7*3) = 41.1mm

8*2=16

41.1+16=57.1mm^2

The surface area of the prism is S = 57.1 mm²

What is the surface area of the prism?

The surface area of the prism is calculated as

The formula for the surface area of a prism is SA=2B+ph, where B, is the area of the base, p represents the perimeter of the base, and h stands for the height of the prism

Surface Area of the prism = 2B + ph

The area of the triangular prism is A = ph + ( 1/2 ) bh

Given data ,

Let the area of the 2 triangles be T

Let the area of the 2 rectangles be R

Let the area of the third side be U

Now , the total surface area of the prism = T + R + U

where T = 2 x ( 1/2 ) ( 4 x 4 )

T = 16 mm²

R = 2 x ( 3 x 4 )

R = 24 mm²

And , U = 5.7 x 3

U = 17.1 mm²

Therefore , the total surface area of prism S = 16 mm² + 24 mm² + 17.1 mm²

S = 57.1 mm²

Hence , the surface area of prism is S = 57.1 mm²

Your friend really wants to buy the newest coolest cell phone which will cost him $310 he gets a job detailing cars and suvs and plans to save all the money he earns if he gets paid $60 to detail a car and $85 to detail an suv which of the following inequalities can be used to determine how many of each he must detail in order to earn at least $310

Answers

Answer:

[tex]60c + 85s \geqslant 310[/tex]

Step-by-step explanation:

He needs to earn at least $310 so $60 per car is 60c and $85 per SUV is 85s. So the answer is the third option.

The required inequality:

60x + 85y >= 310

What is inequality?

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign ()" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than.

Given, a person gets paid $60 to detail a car and $85 to detail an SUV.

Let's assume he needs to detail x number of cars and y number of SUVs to earn at least $310.

Then, the amount earned by detailing x cars and y SUVs can be expressed as:

60x + 85y

According to the problem statement, he wants to earn at least $310, so we can write the inequality:

60x + 85y >= 310

This is the required inequality to determine the number of cars and SUVs he needs to detail in order to earn at least $310.
