The right answer for the question that is being asked and shown above is that:

This can be answered using the Pythagorean Theorem.
h2 = a2 + b2
h = square root (10^2 + 7^2)
h = square root (100 + 49)
h = square root (149) cm

So the correct answer is h = square root (149) cm

At a certain real estate firm, realtors selling homes receive a commission of: 7% for the first $100,000 of the selling price, a

scoray [572]

Answer: The actual price of house sold at $109000.

Step-by-step explanation:

Since we have given that

Selling price = $100000

Rate of commission = 7%

So, Amount of commission would be

$\dfrac{7}{100}\times 100000\\\\\=\$7000$

Total commission = $7540

So, Remaining amount of commission would be

$\$7540-\$7000\\\\=\$540$

Rate of commission exceeding $100000 = 6%

Let the selling price of house be 'x'.

According to question,

$\dfrac{6}{100}\times x=540\\\\0.06x=540\\\\x=\dfrac{540}{0.06}\\\\x=\$9000$

Hence, the actual price of house sold at

$100000+$9000=$109000.

Suppose that the dollar cost of producing x appliances is c(x)=1000+ 90x- 0.2x 2

Aleksandr [31]

Answer:

Step-by-step explanation:

Given that the dollar cost of producing x appliances is

$c(x)=1000+ 90x- 0.2x^2$

A) Average cost can be obtained by dividing c(x) by units = x

i.e. average cost = $\frac{1000}{x} +90-0.2x$

B) Marginal cost = dC/dx = $90-0.4x$

When x=140 marginal cost $= 90-0.4(140)\\=34$

C) We calculate

c(140) = $=1000+90(140)-0.2(140^2)\\\\=9680$

c(141) = $=1000+90(141)-0.2(141^2)\\\\\\=9713.80$

Marginal cost = difference = 33.80

Same as 34 shown in marginal cost.

5. Rhombus- all sides have an equal length, opposite sides are parallel, and opposite angles are equal
6. Kite- have two pairs of sides, each made up of adjacent sides that are equal in length. Angles are equal where pairs meet.

Logan can iron 40 shirts per hour, and Sarah can iron 35 shirts per hour. Logan and Sarah worked a combined 13 hours and ironed

san4es73 [151]

Answer:

Logan - 7 hours

Sarah - 6 hours

Step-by-step explanation:

Given Logan can iron 40 shirts per hour, and Sarah can iron 35 shirts per hour.

Also given that they worked together a combined hours of 13 hours

Let the number of hours worked by Logan is x and the number of hours worked by Sarah be y hours

Given x + y = 13

Also given that they together ironed 490 shirt's

which means 40x + 35y = 490

solve the above two equations by elimination

Multiply the first equation with 35 and subtract from the second equation we get

40x - 35x = 490 - 455

5x = 35

x = 7 hours

Substitute this value in the first equation to get the values of y

x + y = 13

y = 13 - x

y = 13 - 7 = 6 hours

therefore the number of hours worked by Logan is 7 hours and the number of hours Sarah worked is 6 hours
