Answer:
76cm²
Step-by-step explanation:
The easiest way to find the area of a compound shape is to break it up into parts. I would divide it into a square and rectangle.
The area of the square is 4 times 4 which equals 16cm.
The area of the rectangle equals 12 times 5 which equals 60cm
Add the two together to end up with 76cm

(7 1/2, 3 1/4) and (7 1/2, 9 1/2)
Answer:
d=13
Step-by-step explanation:
D = √(x2 - x1)2 + (y2 - y1)2
D = √(-6 - (-8))2 + (1 - 4)2
D = √(-6 + 8)2 + (-3)2
D = √(2)2 + (-3)2
D = √4 + 9
D = √13

A manufacturer wants to design a container with a volume of 800 cubic centimeters. Their old container is shown
Answer:
2.05 cm
Step-by-step explanation:
3.14× (n+3)²×10 = 800
31.4(n+3)²=800
(n+3)²= 800/31.4
(n+3)²= 25.48
n+3 =√25.48
n+3= 5.05
n = 5.05 -3 = 2.05
so, the radius should be increased :
2.05 cm

Money in a bank triples every 9 years. If $100 is deposited today, what will it's value be after 36 years?
Answer:
[tex]\$8,100[/tex]
Step-by-step explanation:
We can denote this increase with the function [tex]y=3^x\cdot 100[/tex], where [tex]y[/tex] is value after [tex]\frac{x}{9}[/tex] years.
Substituting [tex]x=36[/tex], we get:
[tex]3^4\cdot 100=\boxed{\$8,100}[/tex]
Answer:
8,100
Step-by-step explanation:
The first 9 years would be 300, then 18 years would be 900, and 27 years it would be 2,700, and finally after 36 years it would be 8,100.
What is the slope and y-intercept of y=-5/4x+4 and the slope and y-intercept of y=3/2x-7
Answer:
Step-by-step explanation:
The slope of y = -5/4x + 4 is -5/4. The y-intercept is 4.

If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of sides? A.20cm B.16cm C.22cm D.23cm
Complete question:
If side x has a length of 15 cm and side y has a length of 4 cm, then which value below could be the length of the third sides? A.20cm B.16cm C.22cm D.23cm
Answer:
B. 16 cm
Step-by-step explanation:
Given;
two lengths of the triangle as 15 cm and 4 cm
The length of the third side of the triangle must be less than the sum of the two given sides.
Length of third side < 15 cm + 4 cm
Length of third side < 19 cm
The only option less than 19 cm is B. 16 cm
Therefore, the correct option is B. 16 cm

Solve using the quadratic formula. Approximate answers to the nearest tenth.
Help
Answer:
x = 2.4 or x = 0.3
Step-by-step explanation:
3x² - 8x + 2 = 0
Quadratic formula
x = {-b ±√b² - 4ac} / 2a
a = 3
b = -8
c = 2
x = {-b ±√b² - 4ac} / 2a
= {-(-8) ±√(-8)² - 4*3*2} / 2*3
= (8 ± √64 - 24) / 6
= (8 ± √40) / 6
= (8 ± 2√10) / 6
= 8/6 ± 2√10/6
= 4/3 ± √10 / 6
x = 4/3 + √10 / 6 or 4/3 - √10 / 6
x = 2.4 or x = 0.3

Since segment AC bisects (aka cuts in half) angle A, this means the two angles CAB and CAD are the same measure. I'll refer to this later as "fact 1".
Triangles ABC and ADC have the shared segment AC between them. By the reflexive property AC = AC. Any segment is equal in length to itself. I'll call this "fact 2" later on.
Similar to fact 1, we have angle ACB = angle ACD. This is because AC bisects angle BCD into two smaller equal halves. I'll call this fact 3
----------------------
To summarize so far, we have these three facts
angle CAB = angle CADAC = ACangle ACB = angle ACDin this exact order, we can use the ASA (angle side angle) congruence property to prove the two triangles are congruent. Facts 1 and 3 refer to the "A" parts of "ASA", while fact 2 refers to the "S" of "ASA". The order matters. Notice how the side is between the angles in question.
------------------------
Once we prove the triangles are congruent, we use CPCTC (corresponding parts of congruent triangles are congruent) to conclude that AB = AD and BC = BD. These pair of sides correspond, so they must be congruent in order for the entire triangles to be congruent overall.
It's like saying you had 2 identical houses, so the front doors must be the same. The houses are the triangles (the larger structure) and the door is an analogy to the sides (which are pieces of the larger structure).
when
[tex] {x}^{3} + a {x}^{2} + 5x + 3[/tex]
is divided by
[tex]x + 2[/tex]
the remainder is b. Determine the value of b
x³ + ax² + 5x + 3. x + 2 = 0
x = -2
(-2)³ + a(-2)² + 5(-2) + 3 = 0
-8 + 4a - 10 + 3 = 0
4a - 15 = 0
4a = 15
a = 15/4
Given that a = two and b = 3, what is the value of (ab)?
Answer:
(ab) = 6
Step-by-step explanation:
a = 2 and b = 3
So, (2(3)) or 2 x 3 = 6
Find the perimeter of the triangle with vertices D(−2, −1), E(3, 2), and F(0, 4). Do not round before calculating the perimeter. After calculating the perimeter, round your answer to the nearest tenth.
Answer: [tex]15.3\ \text{units}[/tex]
Step-by-step explanation:
Given
Coordinates of the corners are D(-2,-1), E(3,2), and F(0,4)
Length DE is
[tex]\Rightarrow DE=\sqrt{(2+1)^2+(3+2)^2}\\\Rightarrow DE=\sqrt{(3)^2+(5)^2}\\\Rightarrow DE=\sqrt{34}\ \text{units}[/tex]
Length EF is
[tex]\Rightarrow EF=\sqrt{(4-2)^2+(0-3)^2}\\\Rightarrow EF=\sqrt{(2)^2+(-3)^2}\\\Rightarrow EF=\sqrt{13}\ \text{units}[/tex]
Length FD is
[tex]\Rightarrow FD=\sqrt{(4+1)^2+(0+2)^2}\\\Rightarrow FD=\sqrt{(5)^2+(2)^2}\\\Rightarrow FD=\sqrt{29}\ \text{units}[/tex]
Perimeter of the triangle is
[tex]\Rightarrow DE+EF+FD=\sqrt{34}+\sqrt{17}+\sqrt{29}\\\Rightarrow DE+EF+FD=15.3\ \text{units}[/tex]

1) Find the distance between -49.75 and 31.5 on a number line.
Answer:
81.25
Step-by-step explanation:
Because you want to know the total distance, calculate how many digits -49.75 is away from 0. It is 49.75 digits away from 0.
Now calculate how many digits 31.5 is away from 0. It is 31.5 digits away from 0.
Finally, add those two distances together so that you know the total distance:
49.75+31.5 = 81.25
