Sally's pet store sells goldfish. The fish they sell, every goldfish needs 4 gallons of water in the tank. Frank's pet store sells goldfish as well. At Frank's every 4 fish need 3 gallons of water. If a customer has a 12 gallon tank, where should they buy the fish from?

Answer:

They are both 122 degrees

Step-by-step explanation:

Answer:

y= 2x+1

Step-by-step explanation:

Using the general linear form y=mx+c

First find the gradient: change in y/change in x

11-5/6-2 = 6/3= 2

y=2x+c

Secondly find out c:

Use one of the coordinats

5= 2(2)+c

5=4+c

-4

1=c

y= 2x+1

Answer:

Step-by-step explanation:

Y = 1/4x - 12

Adding 12 on both sides

12y = 1/4x

12y/ 1/4 = x

3y = x

messed up, thought it said 2 lol ignore my answer

Answer:

Subject 's' in terms of 't'

  [tex]s = \frac{t-4}{5}[/tex]

Step-by-step explanation:

Explanation:-

Given that the subject 't in terms are 's'

Given that t = 5 s +4

subtracting '4' on both sides, we get

t - 4 = 5s +4-4

 t - 4 = 5 s

Dividing '5' on both sides ,we get

  [tex]\frac{t-4}{5} = \frac{5s}{5}[/tex]

   [tex]\frac{5s}{5 } = \frac{t-4}{5}[/tex]

    [tex]s = \frac{t-4}{5}[/tex]

I have attached an image of the triangle.

BC = 9 cm

Answer:

CE = 7.2 cm

Step-by-step explanation:

In the attached triangle, we see that;

AB = AC = 7.5cm

BC = 9 cm

AD = 6cm

BC = 9cm

Formula for area of triangle is given as;

A = ½bh

Where b is base and h is height.

For the ∆ ABC with BC as base,

Area = ½ × 9 × 6 = 27 m²

Similarly, For ∆ ABC with AB as base,

Area = ½ × 7.5 × CE

Now, area from earlier is 27 cm²

Thus;

½ × 7.5 × CE = 27

Multiply both sides by 2 to get;

7.5CE = 54

CE = 54/7.5

CE = 7.2 cm

Answer:

28 decrease

Step-by-step explanation:

2,500 - 1,800 = 700

700/2500 x 100 = 28

So its 28% decrease.

Answer:

need to find the area of the circular dining room table which has a radius of 3 feet of each person sitting at the table needs about 2 feet of space how many people will fit at the table 3 feet of each person sitting at table needs about two feet of space than about five people will fit at the table

Answer:

False

Step-by-step explanation:

All measures of triangle add up to 180°

[tex]A + B + C = 180[/tex]

[tex]62 + 93 + 35 = 190[/tex]

[tex]190 \neq 180[/tex]

[tex]62 + 93 + 25 = 180[/tex]

the third measure is [tex]25[/tex] not [tex]35[/tex].

plz mark me brainliest ;)

The formula to calculate mean= Add the numbers and Divide by how many numbers( there are 7 numbers)..............

If the answer is wrong.....

Sorry, because I read in class nine........

Answer:

0.29 = 29% = [tex]\frac{29}{100}[/tex]

35% = 0.35 = [tex]\frac{7}{20}[/tex]

[tex]\frac{2}{5}[/tex]= 0.40 = 40%

Answer:

Option (3)

Step-by-step explanation:

Formula to calculate the surface area of a cardboard box in the shape of a cube is,

Surface area = 6(Side)²

If the length of the each side of the box is = 3 feet

Surface area of the cube = 6(3)²

                                          = 6 × 9

                                           = 54 square feet

Therefore, Surface area of the box in the shape of a cube is 54 square feet.

Option (3) is the correct option.

Answer:

x = 16.20

Step-by-step explanation:

tan48 = 18/x

xtan48 = 18

x = 18/tan48

x = 16.20

Answer:

The value of y = 7.5 and the scale factor is 2/3.

Step-by-step explanation:

To get the scale factor, let's get the ratio of 17 to 25

[tex] \frac{17}{25.5} = \frac{2}{3} [/tex]

To check if 17 really is the 2/3 of 25.5

[tex]17 = \frac{2}{3} \times 25.5 \\ 17 = \frac{51}{3} \\ 17 = 17[/tex]

Therefore, if 17 is the 2/3 of 25.5, then the line (3y-3.5) is also the 2/3 of (3y+6).

[tex]3y - 3.5 = \frac{2}{3} (3y + 6) \\ 3(3y - 3.5) = 2(3y + 6) \\ 9y - 10.5 = 6y + 12 \\ 9y - 6y = 12 + 10.5 \\ 3y = 22.5 \\ y = 7.5[/tex]

Answer:

1571 ft^3

Step-by-step explanation:

Given data

diameter= 20ft

radius= 20/2= 10 ft

Height= 5ft

Volume of cylinder = πr^2h

Substitute

V= 3.142*10^2*5

V= 3.142*100*5

V= 1571 ft^3

Hence the volume is 1571 ft^3

Answer:

1580.8 ft^3

Step-by-step explanation:

Answer: 38

Step-by-step explanation:

Answer:

38

Step-by-step explanation:

Let's use benchmark fractions

What is 10% of 40?

that's 40/10 which is 4

What is half of 4?

4/2 = 2

That means 5% of 40 is 2

So then we do 40 - 2 = 38

The other way we can do it is by using percent proportions:

[tex]\frac{x}{95} \frac{40}{100} \\do:\\x=\frac{95 * 40}{100}[/tex]

[tex]x=\frac{3800}{100}[/tex]

[tex]x=38[/tex]

Answer:

Step-by-step explanation:

3y = -x + 6

y = -1/3x + 2

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

y - 3 = -1/3x - 1/3

y - 9/3 = -1/3x - 1/3

y = -1/3x + 8/3

Answer:

1) -10

2) 1

Step-by-step explanation:

1)  (-5) - 5

- Removing the brackets won't change anything since it is subtraction, so now it will be - 5-5 which is equal to -10.

-5 -5 = -10

2) (-10) + 11

- The same case applies here since it is addition.

-10 + 11 = 1

Answer:

1) -10

2) -1

Step-by-step explanation:

[tex]( - 5) - 5 = - 10 \\ \\ ( - 10) + 11 = - 1 \: [/tex]
