Answer:

-2/3 gallon/minute

Step-by-step explanation:

In three minutes the water volume has decreased by 2 gallons (7 less 5 is 2).  The unit rate of decrease of the amount of water in the tank is thus:

- 2 gallons

------------------- = -2/3 gallon/minute

 3 minutes

Answer:

-1

Step-by-step explanation:

the slope of this one is y=x-21

in order for it to be perpendicular the sign changes and the slope flips

but because the slope is 1 you just change the slope to -1

Answer:

13 1/3 pounds

Step-by-step explanation:

Hi! Each bad weighs 2 2/3 pounds. There were 5 bags bought so we multiply. Here is the expression:

2 2/3 x 5 = x

Now we need to convert 2 2/3 into an improper fraction, which is 8/3.

Easy! Now

8          5         40

-      x    -     =    -

3           1          3

*I tried to set it up like fractions.*

Simplify 40/3 and you get 13 1/3

368 divided by 3= 123

123+100= 223

Answer:

1st time: 50% chance or 8/16 chance

2nd time: 46% chance or 7/15

I can try again if its wrong

Answer:

7/30

Step-by-step explanation:

8/16 that she picks a red cube.

7/15 that she picks another red cube after keeping the first red cube.

multiply 8/16 (1/2) times 7/15 to get 7/30 as your final answer

Answer:

D: 11

Step-by-step explanation:

4(x + 2) - 17 = 35

4x+8 - 17=35

4x-9=35

4x=35+9=44

x=44/4=11

Answer:

[tex]5\frac{1}{8}[/tex]

Step-by-step explanation:

5 3/4 = 23/4

(23/4)2 = 46/8

46/8 - 5/8 = 41/8 = 5 1/8

Answer:

3) 2[tex]x^{2}[/tex] + 3x - 1

Step-by-step explanation:

A quadratic expression is an expression involving a squared term

It can be written as y = a[tex]x^{2}[/tex] + bx + c, where a ≠ 0

// note that here b and c can be equal to 0

1) 6[tex]x^{4}[/tex] - 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a quartic function, since the unknown variable x in forth degree. It can be written as y = a[tex]x^{4}[/tex] +b[tex]x^{3}[/tex] +c[tex]x^{2}[/tex] + dx + e, where a before [tex]x^{4}[/tex] ≠ 0

2) 5[tex]x^{3}[/tex]  + 3[tex]x^{2}[/tex]  - 7x - 8 is simply incorrect because you can't write in the previously mentioned form. It is a cubic function, since the unknown variable x in third degree.

3) 2[tex]x^{2}[/tex] + 3x - 1 is correct

4) 3x - 1 is incorrect because there is no squared term. You could also say that here a = 0 and write it as y = 0 * [tex]x^{2}[/tex]  + 3x - 1. It is also called a linear function because if you'd draw a graph, it would be a line

Answer:

The time it takes to boil 2.2 litres of water is approximately 141 seconds

Step-by-step explanation:

The given parameters are;

The relationship of the variables, T and A is a proportional, therefore, we have;

T ∝ A, or T/A = k = Constant of proportionality

The time it takes to boil 2.8 liters of water = 180 seconds

∴ When A = 2.8 litres, T = 180 seconds, from which we have;

k = T/A = 180 s/(2.8 L) = 450/7 s/L

k = 450/7 s/L

When A = 2.2 litres, we have;

T/A = k

∴ T = k × A

Plugging in the value for both 'k', and 'A' when A = 2.2 litres, gives;

T = k × A = 450/7 s/L × 2.2 L = 990/7 s = 141.[tex]\overline{428571}[/tex] s

The time it takes to boil 2.2 litres of water, given a direct proportionality relation is, T = 141.[tex]\overline{428571}[/tex] seconds ≈ 141 seconds given to the nearest second.

Answer:

1/4th Cup left

Step-by-step explanation:

1/2 cup is equal to 2/4 cup, so subtract that from 3/4th and you end with 1/4th

Answer:

Its below in the explanation

Step-by-step explanation:

2^2 = 4 so y=4 and x,y = 2,4

3^2 = 9 and x,y = 3,9

4^2=16 and x,y=4,16

Please give me brainliest

Answer:

2^2 = 4 so y=4 and x,y = 2,4

3^2 = 9 and x,y = 3,9

4^2=16 and x,y=4,16

Step-by-step explanation:

Answer:

area of big rectangle=l×b=12×18=216cm²

area of smaller square=l²=8²=64cm²

area of shaded area =area of (bigger rectangle-smaller square)=216-64=152cm²

Answer: x = 5

Step-by-step explanation:

The area of a rectangle is the length times the width. Since the dimensions are given as functions of x, youre going to have to use FOIL to combine them, then set that answer equal to the given value of 72.

l*w = (x+3)*(x+4) = x^2 + 7x +12 = 72

Subtract 72 on both sides. There is a reason why we'll do this instead of subtracting 12. The quadratic formula will help us to solve for x.

x^2 + 7x - 60 = 0

Apply the quadratic formula

[tex]\frac{-7 (+/-)\sqrt{7^2-(4)*(1)*(-60} }{2*1} =\frac{-7(+/-)17}{2}[/tex]

We cant have a negative x value because that would result in negative dimensions and a negative area, which is impossible in this context. So you want to add the 17 instead of subtracting it.

x = 5 and x = -12

An alternate way is just factoring the trinomial to:

(x+12)(x-5) = 0

Answer:

20 units square

Step-by-step explanation:

do the Pythagoras theorem

a²=b²+c² ⇒ a=√b²+c²

if b is 4 and c is 2 an a is the unknown

so a=√(4)²+(2)²

a=√20

then get the rule of the area of the square

Area of the square= s²

s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)

so s²=20

Area of the square=20 units square

Answer:

Side A = 4

Side B = 5

Side C = 6

Step-by-step explanation:

In the following equation, variable a is the length of Side A

a + (a + 1) + (a + 2) = 15

a + a + a + 1 + 2 = 15

3a + 3 = 15

     - 3    - 3

3a (÷ 3) = 12 (÷ 3)

a = 4

Side A = 4

Side B = (a + 1) = (4 + 1) = 5

Side C = (a + 2) = (4 + 2) = 6
