Given the following rectangle: Solve for x.
10x - 43
3x + 6
(The answer is not 27)

Answer:

Step-by-step explanation:

difference of x-coordinates = 4-(-6) = 10

difference of y-coordinates = -1-9 = -10

partition the differences into a ratio of 1:4

10 × 1/(1+4) = 2

-10 × 1/(1+4) = -2

(-6+2,9-2) = (-4,7)

Answer:

Yes, Friend is correct.

Step-by-step explanation:

Given:

Tan B = √3

Find:

Value of B

By comparing

B = 60°

Yes, Friend is correct.

Answer:

10 by 8

Step-by-step explanation:

The perimater is 80 so number are added. The area would be a square 10 by 8 if you multiply 10 by 8 it will give you 80.

Answer:

C

Step-by-step explanation:

Remember that we can use the discriminant to determine the amount of roots that a quadratic function has.

If the determinant equals 0, then we only have one real root.

Our function is given by:

[tex]f(x)=x^2+bx+9[/tex]

Then the discriminant will be:

[tex]\Delta = b^2-4(1)(9)=b^2-36[/tex]

We only have one real root, thus our discriminant must be 0:

[tex]0=b^2-36[/tex]

Solve for b:

[tex]b^2=36[/tex]

Thus:

[tex]b=\pm 6[/tex]

The answer is both II and III.

The final answer, then, is C.

Answer:

The order of arithmetic calculations is

Answer:

1200 ounces

Step-by-step explanation:

How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?

Let us represent

Number of ounce of 10% copper = x

Hence, our Equation =

x × 10% + 600 × 70% = (x + 600) × 30%

0.1x + 420 = (x + 600)0.3

0.1x + 420 = 0.3x + 180

Collect like terms

0.3x - 0.1x = 420 - 180

0.2x = 240

x = 240/0.2

x = 1200 ounces

Answer:

width = 40 cm

Step-by-step explanation:

Since the pentagons are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{4x}{x}[/tex] = [tex]\frac{48}{x+2}[/tex] ( cross- multiply )

4x(x + 2) = 48x ← distribute left side

4x² + 8x = 48x ( subtract 48x from both sides )

4x² - 40x = 0 ← factor out 4x from each term on left side

4x(x - 10) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

x - 10 = 0 ⇒ x = 10

However, x > 0 then x = 10

Thus width = 4x = 4 × 10 = 40 cm

Step-by-step explanation:

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?

This is a simple interest question

The formula to find the rate is given as:

Equation:

r = (1/t)(A/P - 1)

t = time = 4 years

P = Principal = $12500

I = Simple Interest = $1500

A = Total Amount = Principal + Simple Interest = $12500 + $1500

= $14000

Calculation:

Solving our equation:

r = (1/4)((14000/12500) - 1) = 0.03

r = 0.03

Converting r decimal to R a percentage

R = 0.03 * 100 = 3%/year

Answer:

between 4 and 20......................

The number should be bigger than difference of both sides and smaller than sum of both sides.

So

12+8=20

12-8=4

So it should be 4<x<20

which means between 4 and 20

Do you really have brown eyes?

Answer:

4 < x < 20

Step-by-step explanation:

Given 2 sides of a triangle then the third side x is in the range

difference of 2 sides < x < sum of 2 sides , that is

12 - 8 < x < 12 + 8

4 < x < 20 ← range of values for third side

Cds sold= 290

Step-by-step explanation:

Giving the following information:

A shop sold 250 CDs last week. The sales of CDs increased by 16% this week.

To calculate the number of CDs sold this week, we need to use the following formula:

Cds sold= Cds sold last week*(1 + percentage increase)

Cds sold= 250*1.16

Cds sold= 290
