You are part of a construction company that is supposed to build houses. An architect has left plans to build houses on each isl

Marrrta [24]

Answer:

<h2>Island A, B and C has 10, 5 and 7 houses respectively.</h2>

Step-by-step explanation:

Let, the three islands A, B and C has a, b and c houses respectively.

According to the question, a + b = 15; a + c = 17; b + c = 12; a + b + c = 22.

Adding [ a + b = 15; a + c = 17]-these two, we get, $a + (a + b + c) = 15 + 17 = 32\\a + 22 = 32\\a = 10$ .

Now, $a + b = 15\\10 + b = 15\\b = 5$ .

$a + c = 17\\10 + c = 17\\c = 7$ .

Which equation represents a line that is perpendicular to line PQ?

valentinak56 [21]

Answer:

B. y=1/3x+4

Step-by-step explanation:

Hi there!

We are given the line PQ and we want to find the line that is perpendicular to it

Perpendicular lines have slopes that are negative and reciprocal. When they are multiplied together, the result is -1

So first, let's find the slope of the line PQ

The point P is given as (-8, 7) and the point Q is given as (-4, -5)

The formula for the slope calculated from two points is $\frac{y_2-y_1}{x_2-x_1}$ where ( $x_{1}$ $y_1$ ) and ( $x_2$ , $y_2$ ) are points

We have the needed information for the slope, but let's label the values of the points to avoid any confusion

x1=-8

y1=7

x2=-4

y2=-5

Now substitute into the formula (m is the slope, and remember: the formula contains SUBTRACTION):

m= $\frac{(-5-7)}{(-4--8)}$

simplify

m= $\frac{-5-7}{-4+8}$

add

m=-12/4

divide

m=-3

So the slope of the line PQ is -3

As said above, perpendicular lines have slopes that have a product of -1

So to find the slope of the line perpendicular to PQ, use this formula:

-3m=-1

divide both sides by -3

m=1/3

The only line that has a slope of 1/3 is B (y=1/3x+4), so B is the answer.

Hope this helps!

You put 500 dollars into your savings account. Your bank account offers a yearly interest rate of 3.5% and you leave the money i

Alex777 [14]

Answer:

87.5

Step-by-step explanation:

87.5 because if your earning a 3.5% of the $500 then that means you're earning 17.5 dollars.in an year therefore in five years you multiply the 17.5 x 5 years which will give you at 87.5 so we've had in total you can get to 587.5 dollars

Manuel has 18 yards of fabric to make table runners. It takes Three-fourths of a yard to make each runner. The expression that r

stira [4]

Inequality helps in comparison. The possible number of table runners that Manuel could make is 20, 22, and 24.

<h3>What is Inequality?</h3>

Inequality helps us to compare two unequal expressions to form an equation.

Given to us

Left over cloth = 18 - (3/4)t

In the given equation, t shows the number of table runners that can be made with 18 yards of fabric.

As the total amount of fabric that is used for making must not be more than 18 yards, we can write the equation as,

$\frac{3}{4}t \leq 18$

solving it for t,

$t \leq 18 \times \dfrac{4}{3}\\\\t \leq 24$

Thus, the number of tables runner that can be made with 18 yards of cloth such that the size of the table runner is $\frac{3}{4} t$ must be equal to less than 24.

Hence, the possible number of table runners that Manuel could make is 20, 22, and 24.
