(22 + 26) ÷ 8 = g (or groups)

Answer:

3b - 2 = 4

Step-by-step explanation:

3(2) = 6

6 - 2 = 4

Answer:

3b − 2 = 4

Step-by-step explanation:

2b + 24 = 30

3b − 2 = 4

b + 4 = 8

2b − 3 = 0

2b + 24 = 30

2(2) + 24 = 30

4 + 24 = 30

28 ≠ 30

-----------------------------------------------------------------------------------------------------------------

3b − 2 = 4

3(2) - 2 = 4

6 - 2 = 4

4 = 4

-----------------------------------------------------------------------------------------------------------------

b + 4 = 8

(2) + 4 = 8

6 ≠ 8

-----------------------------------------------------------------------------------------------------------------

2b - 3 = 0

2(2) - 3 = 0

4 - 3 = 0

1 ≠ 0

Step-by-step explanation:

3x+6= 3(x+2)

       = 3x+6

x-2= -(-x+2)

   =  x -2

Answer:

Volume of cone = 209.44 cm²

Curved surface area of cone = 188.57 cm

Step-by-step explanation:

Given:

Height h = 8 cm

Slant height l = 10 cm

Radius r = 6 cm

Find:

Volume of cone

Curved surface area of cone

Computation:

Volume of cone = (1/3)πr²h

Volume of cone = (1/3)π(5)²(8)

Volume of cone = 209.44 cm²

Curved surface area of cone = πrl

Curved surface area of cone = π(6)(10)

Curved surface area of cone = 188.57 cm

Answer:

0.5826 units

Step-by-step explanation:

We are given that the area of a parallelogram is given by the equation

[tex]x^2+8x-5=0[/tex]

Where x= Length of base

We have to find the length of base

[tex]D=b^2-4ac[/tex]

We have

a=1,b=8,c=-5

Using the formula

[tex]D=8^2-4\times (-5)=84[/tex]>0

Now,

[tex]x=\frac{-b\pm \sqrt{84}}{2a}[/tex]

Using the formula

[tex]x=\frac{-8\pm \sqrt{84}}{2}[/tex]

[tex]x=\frac{-8\pm 2\sqrt{21}}{2}[/tex]

[tex]x=\frac{-8+2\sqrt{21}}{2}=-4+\sqrt{21}[/tex]

[tex]x=-4+4.5826=0.5826[/tex]

[tex]x=\frac{-8-2\sqrt{21}}{2}=-4-4.5826=-8.5826[/tex]

Length of base cannot be negative

Therefore, the length of base=0.5826 units

Answer:

y=4x+1

Step-by-step explanation:

slope intersect form is y=Mx+b

Answer:

By multiplying the run by the slope, we get the rise value

Step-by-step explanation:

Mathematically. we have

slope = rise/run

Now, given that we know the run and we have the value of the slope, how can we get the rise

To get the rise, we simply have to multiply the run by the value of the slope

Hence, multiplying the run by the value of the slope will give the value of the vertical distance which is the rise

Answer:

13 years

Step-by-step explanation:

First we will have to see how much she owns her aunt:

800-448= 362

8% of 348 = 27.84

362 ÷ 27.84 = 13 years

I might be wrong but hopefully this helps :)

because 9.39 is closer

Answer

The function is x3

Given:

The descriptions and equations. The equations are

[tex]y=4x[/tex]

[tex]y=x+4[/tex]

To find:

The correct description for each equation and match them.

Solution:

We know that, "+" is used for more and "×" is used for times.

Additive: y is 4 more than x.

[tex]y=x+4[/tex]

Additive: x is 4 more than y.

[tex]x=y+4[/tex]

Multiplicative: y is 4 times x.

[tex]y=4x[/tex]

Multiplicative: x is 4 times y

[tex]x=4y[/tex]

Therefore, the correct description for the equation [tex]y=4x[/tex] is "Multiplicative: y is 4 times x " and the correct description for the equation [tex]y=x+4[/tex] is "Additive: y is 4 more than x. "

Step-by-step explanation:

What Julie did wrong was, she did simplify she just did it wrong. She used 4*8 which does equal 32 but 8 can't be simplified anymore than that. If she would of used 2*16 then her answer would be right.

Hope this helps!

Answer:

[tex]5 \sqrt{18} - \sqrt{32} \\ = 5 \sqrt{9 \times 2} - \sqrt{4 \times 4 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }[/tex]

Step-by-step explanation:

Answer:

0.625

Step-by-step explanation:

The value of expression 0.5 divided by 0.8 would be; 0.625

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the expression of  0.5 divided by 0.8

A negative divided by a negative is positive, then we get;

0.5 / 0.8 = 0.625

Therefore, The value of expression 0.5 divided by 0.8 would be; 0.625

W^2 - v + 1 Is represented as (-2)^2 - (-8) + 1

Answer:

Step-by-step explanation:

Remark

Begin by omitting all the pqrs bases that are raised the 0 power. Anything to the zero power = 1.

Multiply what is left.

Solution

Group One: p^-1

Group Two: p^-1 q^-3 s^-1

Group Three: q^-1r^-2s^-1

From groups 1 and 2 p is p^-2

From groups 2 and 3 q is q^-4

From groups  3 r is r^-2

From groups 2 and 3 s is s^-2

Notice that when the powers are - when the power is in the numerator, those powers become positive when they switch to the denominator.

Answer

[tex]\frac{1}{p^2 q^4 r^2 s^2}[/tex]
