Answer:

$644

Step-by-step explanation:

Let X (40hrs)be the number of hours Avery works per week, and i (15%)be the raise and that her wage rate is $14/hr:

Total earnings per week is therefore:

Earnings=14X(1+i)

Avery's earning per week is calculated as:

Earnings=14X(1+i)\\\\=14\times 40(1+0.15)\\\\=644

Hence, Avery's weekly earning is $644

12. Consider the general rational equation a/b=c/d
velikii [3]

Part (a)

Answer:  ad = bc

-------------------------

Explanation:

In the equation a/b = c/d, we have b and d in the denominator.

If we multiply both sides by bd, then the denominators will cancel. The expression bd is the same as bd/1.

As a similar example, consider the equation

a/b = 12

if we multiply both sides by b, then we clear out the denominator to end up with a = 12b

As another example, let's consider

a/b = c

Multiplying both sides by b leads to

a = bc

The same idea applies with the denominator d as well.

When going from a/b = c/d to ad = bc, your textbook may refer to this process as "cross multiplication".

=================================================

Part (b)

Answer:  bd is the product of the denominators

-------------------------

Explanation:

Often in math, writing two variables next to each other represents multiplication.

bd is the same as b*d which means "b times d". The term "product" is the result of multiplying two or more values.

b and d are both in the denominator of each fraction, so bd represents the product of the denominators.

A zookeeper predicted the weight of a new baby elephant to be 261 pounds when it was born. The elephant actually weighed 293 pou
Papessa [141]
Percent error=|\frac{predicted value-actual value}{predicted value}| times 100
(note the || is absolute value, means that whatever the result is inside, it is made positive)

predicted value=261
actual value=293
subsitute
percent error=|\frac{261-293}{261}| times 100
so using pemdas
do parenthasees first
|\frac{-32}{261}|
|-0.12|
absolute value
0.1226

time 100
0.1226 times 100=12.26
answer is 12.26%
answer is B

Ahat [919]

Given:

A person leaves work and travels west for 15 miles.

They then turn left and travel south for 10 miles, to their home.

To find:

Distance between work place and home.

Solution:

The person travels west for 15 miles, then travel south for 10 miles.

It means, it forms a right angle triangle with legs 15 and 10.

To find the distance between work place and home we need to find the hypotenuse of the triangle.

Pythagoras theorem:

Hypotenuse^2=Base^2+Perpendicualr^2

(OB)^2=(15)^2+(10)^2

(OB)^2=225+100

(OB)^2=325

Taking square root on both sides.

OB=\sqrt{325}

OB=\approx 18.03

Therefore, the bird would fly 18.03 miles.

zalisa [80]

Answer:

5 pounds

Step-by-step explanation:

  • To find that we simply solve the system of equations
  • So make c the subject of the formula of equation 2
  • s+c=9\\c=9-s
  • Substitute in equation 1
  • 5s+3c=37\\5s+3(9-s)=37\\5s+27-3s=37\\5s-3s+27-(27)=37-(27)\\2s=10\\s=5 so that's 5 pounds of salmon
