Answer:

72 square feet.

Step-by-step explanation:

You could do this by figuring out directly how many tiles are needed to make the border B...

It is easier to find the area of the large area and subtract the white pool

Large rectangle = 18 * 9 = 162

Small rectangle = 15 * 6 = 90       Subtract

Area of border =               72

(A): 825

(B): 42,900

The percentage 0.76 when convert to fraction is: 76/100.

0.76 is a percentage which represent 76% when multiply by 100 calculated as:

0.76×100

=76%

Now 0.76 as a fraction or quotient will be 76/100 in which the numerator is 76 and the denominator is 100 and when you divide 76 by 100 we would arrive at 0.76.

Inconclusion 0.76 as a fraction is: 76/100.

Answer:

Patricia spent $24 on presents, while Donald spent $12 and Carl spent $36.

Step-by-step explanation:

The problem is to solve how much money each person spent on presents in the year, through a series of equivalences. In order to determine how much money each one spent, the following equation must be proposed:

Patricia = X

Donald = 1 / 2X

Carl = 3/2 X

X + 1 / 2X + 3 / 2X = 72

1X + 0.5 X + 1.5 X = 72

3X = 72

X = 72/3

X = 24

Thus, Patricia spent $ 24 on presents, while Donald spent $ 12 (2/24) and Carl spent $ 36 (1.5 x 24).

(-1, 0), (0, -4), (1, -6) points are solutions of the given quadratic equation.

A quadratic equation is an equation where the variable has the highest power of 2.

Given equation is y = x² - 3x - 4

1. For (-4, 0), L.H.S = 0, R.HS = (- 4)² - 3(- 4) - 4 = 24.

Hence, (-4, 0) is not a solution of the given equation.

2. For (-1, 0), L.H.S = 0, R.HS = (- 1)² - 3(- 1) - 4 = 0.

Hence, (-1, 0) is a solution of the given equation.

3. For (0, -4), L.H.S = -4, R.HS = (0)² - 3( 0) - 4 = - 4

Hence, (0, -4) is a solution of the given equation.

4. For (1, -6), L.H.S = -6, R.HS = (1)² - 3(1) - 4 = -6.

Hence, (1, -6) is a solution of the given equation.

5. For (1, 0), L.H.S = 0, R.HS = (1)² - 3(1) - 4 = -6.

Hence, (1, 0) is not a solution of the given equation.

6. For (3, -7), L.H.S = -7, R.HS = (3)² - 3(3) - 4 = -4.

Hence, (3, -7) is not a solution of the given equation.

BRAINLIEST PLEASE

Given:

Elena has a pet parakeet that weighs 6 when measured in one unit and 170 when measured in a different unit.

6__________ = 170______

To find:

The correct units from grams and ounces for these blanks.

Solution:

We know that, 1 ounce is greater than 1 gram.

1 ounce = 28.3495 grams

Multiply both sides by 6.

6 ounces = 170.097 grams

Approximate the values to the nearest whole number.

6 ounces = 170 grams

Therefore, 6 ounces = 170 grams.

Answer:

Step-by-step explanation:

We will need 2 different equations for this problem. For compounding a certain number of times a year, the formula is

[tex]A(t)=P(1+\frac{r}{n})^{nt}[/tex] so let's do that first. Filling in we get

[tex]A(t)=10000(1+\frac{.03}{4})^{(4)(5)[/tex] and simplifying a bit gives us

[tex]A(t)=10000(1+.0075)^{20}[/tex] and a bit more,

[tex]A(t)=10000(1.0075)^{20}[/tex] and then

A(t) = 10000(1.161184142) so

A(t) = 11611.84

Then for the compounding continuously, the formula is

[tex]A(t)=Pe^{rt[/tex]

[tex]A(t)=10000e^{(.03)(5)}[/tex] and simplify a bit to\

[tex]A(t)=10000e^{.15}[/tex] Now raise e to the power of .15 on your calculator to get

A(t) = 10000(1.161834243) so

A(t) = 11618.34

Not too much of a difference between the 2 values at the end.

Answer:

  37.5% decrease

Step-by-step explanation:

The percentage change is given by the formula ...

  pct change = ((new price) -(original price))/(original price) × 100%

  = (50 -80)/80 × 100%

  = -3/8 × 100% = -37.5%

The negative sign indicates a decrease.

The decrease in price is 37.5%.
