Answer:

[tex]\sqrt{28} = 2\sqrt{7}[/tex]

[tex]\sqrt {500} = 10 \sqrt {5[/tex]

[tex]\sqrt {162} = 9 \sqrt {2[/tex]

Step-by-step explanation:

Given (Correct Parameters)

[tex]\sqrt {28[/tex]

[tex]\sqrt {500[/tex]

[tex]\sqrt {162[/tex]

Required

Express in simplified form

[tex]\sqrt {28[/tex]

Express 28 as 4 * 7

[tex]\sqrt{28} = \sqrt{4} * \sqrt{7}[/tex]

Take positive square root of 4

[tex]\sqrt{28} = 2 * \sqrt{7}[/tex]

[tex]\sqrt{28} = 2\sqrt{7}[/tex]

[tex]\sqrt {500[/tex]

Express 500 as 100 * 5

[tex]\sqrt {500} = \sqrt {100} * \sqrt {5[/tex]

Take positive square root of 100

[tex]\sqrt {500} = 10 * \sqrt {5[/tex]

[tex]\sqrt {500} = 10 \sqrt {5[/tex]

[tex]\sqrt {162[/tex]

Express 162 as 81 *2

[tex]\sqrt {162} = \sqrt {81} * \sqrt {2[/tex]

Take positive square root of 81

[tex]\sqrt {162} = 9 * \sqrt {2[/tex]

[tex]\sqrt {162} = 9 \sqrt {2[/tex]

Answer:

89 km/hr

Step-by-step explanation:

Distance = Rate(speed) × Time

D = R × T

T = 4 hours

One car's rate is 12 kilometers per hour less than the other's.

Hence:

First's car's rate = r × 4 = 4r

Second car's distance = (r + 12) × 4 = 4r + 48

4r + 4r + 48 = 760

8r + 48 = 760

8r = 760 - 48

8r = 712

r = 712/8

r = 89 km/hr

The rate of the slower car is 89 km/hr

Answer:

The equation of the parabola is (x - 4)² = -16(y - 1)

Step-by-step explanation:

The standard form of the equation of the parabola is (x - h)² = 4p(y - k), where

∵ The focus of the parabola is (4, -3)

∵ The focus is (h, k + p)

∴ h = 4

∴ k + p = -3 ⇒ (1)

∵ It has a directrix of y = 5

∵ The directrix of the parabola is y = k - p

∴ k - p = 5 ⇒ (2)

→ Add equations (1) and (2) to find k and p

∵ (k + k) + (p - p) = (-3 + 5)

∴ 2k + 0 = 2

∴ 2k = 2

→ Divide both sides by 2

∴ k = 1

→ Substitute the value of k in equation (1)

∵ 1 + p = -3

→ Subtract 1 from both sides

∴ 1 - 1 + p = -3 - 1

∴ p = -4

∵ The form of the equation of the parabola is (x - h)² = 4p(y - k)

→ Substitute the values of h, k, p in it

∴ (x - 4)² = 4(-4)(y - 1)

∴ (x - 4)² = -16(y - 1)

∴ The equation of the parabola is (x - 4)² = -16(y - 1)

Answer:

[tex]Side_2 = 74\ in[/tex]

Step-by-step explanation:

Given

[tex]Side_1= 82\ in[/tex]

[tex]Area = 6068\ in^2[/tex]

Required

Determine the length of the other side

For a rectangle:

[tex]Area = Side_1 * Side_2[/tex]

This gives:

[tex]6068\ in^2 = 82\ in * Side_2[/tex]

Divide both sides by 82in

[tex]\frac{6068\ in^2}{82\ in} = \frac{82\ in}{82\ in} * Side_2[/tex]

[tex]\frac{6068\ in^2}{82\ in} = Side_2[/tex]

[tex]Side_2 = \frac{6068\ in^2}{82\ in}[/tex]

[tex]Side_2 = 74\ in[/tex]

Hence, the length of the other side is 74 inches

Answer:

8736

Step-by-step explanation:

The LCM of 156 and 224

First find the highest common factor between the two number

156 = 4 * 39

224 = 4 * 56

Since 4 is the highest common factor between both numbers, the LCM of 156 and 224 will be the product of the highest common factor and the other multiples that are left when the numbers are divided by the highest common factor.

As such, the LCM of 156 and 224

= 4 * 39 * 56

= 8736

Answer:

8736

Step-by-step explanation:

The LCM of 156 and 224

First find the highest common factor between the two number

156 = 4 * 39

224 = 4 * 56

Since 4 is the highest common factor between both numbers, the LCM of 156 and 224 will be the product of the highest common factor and the other multiples that are left when the numbers are divided by the highest common factor.

As such, the LCM of 156 and 224

Answer:

Store 1

Step-by-step explanation:

Given

See attachment

Required

Determine the store with the best price per unit

It should be noted that the store with the best has the least price per unit.

So, we have:

Store 1

[tex]Quantity = 10\ ft[/tex]

[tex]Price = \$2.50[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$2.50}{10\ ft}[/tex]

Rate = $0.250 per feet

Store 2

[tex]Quantity = 2\ yd[/tex]

[tex]Price = \$1.85[/tex]

Convert quantity to feet

[tex]Quantity = 2 * 3ft = 6ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$1.85}{6\ ft}[/tex]

Rate = $0.308 per feet

Store 3

[tex]Quantity = 12\ ft[/tex]

[tex]Price = \$3.40[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$3.40}{12\ ft}[/tex]

Rate = $0.283 per feet

Store 4

[tex]Quantity = 5\ yd[/tex]

[tex]Price = \$4.00[/tex]

Convert quantity to feet

[tex]Quantity = 5 * 3ft = 15ft[/tex]

The unit rate is:

[tex]Rate = \frac{Price}{Quantity}[/tex]

[tex]Rate = \frac{\$4.00}{15\ ft}[/tex]

Rate = $0.267 per feet

From the calculations above; store 1 has the least unit rate.

Hence, store 1 has the best price per unit

Answer:

to get rid of the 3 on the x you have to divide it by 3. whatever you do to one side you have to do to the other side so the answer would be x=8

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

To get the variable alone you would divide both sides by 3. You do this because 3 is a common factor that both 3 and 24 have. Once you divide 3 on each side, you have x = 8 as your final answer.

Answer:

1

Step-by-step explanation:

The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.

The coefficient  of z in the expression 3x- 4y +z is 1.

A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:

Given:

3x - 4y + z

As, we know a coefficient is a number that is multiplied by a variable.

So, the coefficient of x is 3, coefficient of y is 4 and coefficient  of z is 1.
