Find the area of the rectangle with the given base and height.
3 ft 3 in
The area of the rectangle is it?
(Type an integer or a simplified fraction.)
Plz help
Answer: Area = 108 in. or 3/4 ft.
Step-by-step explanation: The formula for the area of a rectangle is l•w (length times width).
To get the area, you need to convert the units of measurement to one or the other (either inches or feet) because you cannot multiply them unless they are the same.
To get the area in inches, you convert 3 ft. to inches which is 36 inches, and then multiply it by 3 inches. You will get that the area = 108 inches.
To get the area in feet, you convert 3 inches to feet which is 1/4 (or 0.25) feet and then multiply it by 3 feet which gives you area = 3/4 ft. (or 0.75 ft.). Hope this helps.
1. How does the distance formula help me know if two or three sides of a triangle are equal?
Determine the number and type of solutions of the quadratic
equation.
4x2 – 3x + 1 = 0
O one real solution
O two imaginary solutions
O one imaginary solution
O two real solutions
Answer: Choice B
Two imaginary solutions
=======================================================
Explanation:
The given equation is
4x^2 - 3x + 1 = 0
Compare this to the general quadratic
ax^2 + bx + c = 0
to find that a = 4, b = -3, c = 1.
Plug those values into the discriminant formula below.
d = b^2 - 4ac
d = (-3)^2 - 4*4*1
d = 9 - 16
d = -7
Then recall that...
If d > 0, then we have two real solutions.If d = 0, then we have only one real solution.If d < 0, then we have two imaginary solutions.We see that d = -7 fits with the third option highlighted above.

a) the equator and 60o latitude
b) 30o latitude and 60o latitude
c) 30o latitude and the poles
d) the equator and 30o latitude
e) the equator and the poles
In the three-cell model of the general circulation, areas of surface low pressure should be found at the equator and 60° latitude.
What is Surface Low Pressure?
In any environment, geographically speaking, the place with the lowest relative pressure is called the surface low-pressure center.
Surface low-pressure centers are created when the atmospheric circulation of air (vertically) reduces a minuscule amount of atmosphere from a geographical region.

I hope this helps you

Answer:
∠ABC = 72°
Step-by-step explanation:
When we look at the triangle carefully, we can see a bar on AC and AB. Those bars define that AC and AB are equivalent. This also means that the triangle is isosceles. Since this triangle is isosceles, the base angles of the triangle are equivalent.
⇒ AB = AC
We also know that the sum of its interior angles must be 180°.
⇒ ∠A + ∠B + ∠C = 180
Let's substitute their angle measures.
⇒ 3x + 6x + 6x = 180 [∠BAC = 3x; ∠ABC = ∠ACB = 6x]
Now, let's solve for x.
⇒ 3x + 6x + 6x = 180
⇒ 15x = 180
⇒ 15x/15 = 180/15
⇒ x = 12
Now, substitute the value of x into "6x" to find ∠ABC.
∠ABC = 6x
⇒ ∠ABC = 6(12)
⇒ ∠ABC = 72°

∠A and ∠B are complementary. The measure of ∠A is 32°. What is the measure of ∠B? Enter your answer in the box. °
Answer:
∠B = 58°
Step-by-step explanation:
∠A and ∠B are complementary.
-> ∠A + ∠B = 90°
-> 32° + ∠B = 90°
-> ∠B = 90° - 32°
-> ∠B = 58°
Answer:
<B = 58
Step-by-step explanation:
complementary angles are angles that sum up to 90°.
If A and B are angle when added will form 90°, to find B we follow the following steps
A + B = 90
if A = 32°,
32 + B = 90
collect like terms
B = 90 - 32
B = 58
that means
32 + 58 = 90
B = 58

of Angle A is 2x + 3. The measure of Angle B is 3x –
5. Solve for x. What is the measure of each Angle?
=========================================
Work Shown:
angle A = angle B
2x+3 = 3x-5
3+5 = 3x-2x
8 = x
x = 8
angle A = 2x+3
angle A = 2*8+3
angle A = 16+3
angle A = 19
angle B = 3x-5
angle B = 3*8-5
angle B = 24-5
angle B = 19
Both angles are the same measure (19), which confirms our answer.
Answer:
X=8
Step-by-step explanation:
2x+3=3x-5. subtract 2x from both sides
3=x-5. add 5 to both sides

An employee at a clothing store makes $12.75 per hour plus a 5.75% commission on sales. This week she worked 45 hours and her sales were $12,675. How much did she earn this week?
Answer:$1,302.56
Step-by-step explanation:
First you must find the amount she made from working her hours.
$12.75 x 45(hours)=$573.75
Next you must find how much she made from her commission on sales.
$12,675 x 0.0575(5.75% converted to a decimal)=728.8125.
Round 728.8125 to the nearest hundredth to get $728.81.
Add these two numbers together.
$728.81+$573.75=$1,302.56
Answer:
$1,302.56
Step-by-step explanation:
You must first determine how much she earned throughout her working hours.
$12.75 multiplied by 45 hours equals $573.75.
The next step is to determine how much she earned from her sales commission.
728.8125 = $12,675 x 0.0575(5.75 percent converted to a decimal).
To get $728.81, round 728.8125 to the nearest hundredth.
These two integers should be added together.
$728.81+$573.75=$1,302.56

Jane made $108 for 9 hours of work.At the same rate, how many hours would she have to work to make $216?
pls help
Answer:
18 hours
Step-by-step explanation:
$108 = 9 hours
$216 = x hours
we want to get to $216 from the original equation. one thing we can do to get there is to figure out what we need to multiply 108 by to get 216. to figure this out, we can calculate 216/108 = 2.
therefore, we can multiply both sides of the original equation by 2 to get
$216 = 9 * 2 hours = 18 hours as our answer

A literary agent makes $30,000 a year plus 13% commission on the sales of her clients' books to publishers. The agent sold 4 books for $175,000 each for her
clients this year.
Find her total earnings.
Answer:
She made $121000.
Step-by-step explanation:
The money the agent sold was:
4*175000=700000 (dollars)
but she only gets 13% of this, so she earned:
700000*0.13=91000 (dollars)
She also makes $30000 per year, so the total income she earned was:
91000+30000=121000

Find the equation of the linear function represented by the table below in slope-intercept form.
x y
-4 0
1 5
6 10
11 15
Answer:
the desired equation is y = x + 4.
Step-by-step explanation:
Slope is defined as m = rise over run. Run is the change (usually an increase) in x, and rise an increase or decrease in y.
We see, in the table, that if x increases from 1 to 6 (a 'run' of 5), y increases from 5 to 10 (a 'rise' of 5). Thus, it's immediately apparent that the slope is m = rise / run = 5 / 5, or just 1.
Using the slope-intercept form of the equation of a straight line, y = mx + b, and the point (1, 5), we calculate b:
5 = 1(1) + b, or b = 4.
Therefore the desired equation is y = x + 4.
A survey asked a group of adults and youths if they prefer reading books printed on paper or electronic books. Results are shown in the table below, but some values are missing. Fill in the missing values.
The missing values for the given two-way table are shown in the image attached below (see attachment).
What is a Two-way Table?A two-way table can be described as table that shows the frequencies of two categorical variables in rows and columns respectively.
To find the missing values in the two-way table that is given, simply subtract a known value from the corresponding given total of a row or column.
Thus:
First row total for print and electronics = 33 + 24 = 57
Second row for electronics = 48 - 24 = 24
Second row total for print and electronics = 32 + 24 = 56
Column total for print = 33 + 32 = 65
Third column for grand total = 57 + 56 = 113
