Answer:
80000
Step-by-step explanation:
Here, we want to write the number in one significant figure
What we have to do here is to simply turn the numbers after 8 to zero
This is because the first number is less than 5
So we have the significant figure as 80000

Answer:
The area of the shaded portion is 450.185 in^2
Step-by-step explanation:
21^2+20^2=841
The square root of 841 is 29
29+20+21=70
70*1/2=35
35-29=6
35-21=14
35-20=15
The square root of 35*6*14*14=210
The area of the triangle is 210 in^2
The diameter of the circle is 29, so the radius is 14.5
14.25^2=210.25
210.25*3.14=660.185
660.185-210=450.185

The given question is incomplete. The complete question is:
Joanna earns $12 per hour at her job. Last week, joanna earns $432
use this information to answer the next question. Which equation can be used to determine the number of hours Joanna worked last week.
a. h+ 12 = 432
b. 432 h =12
c. 12 h = 432
d. [tex]\frac{1}{12} h=432[/tex]
Answer: c. 12 h = 432
Step-by-step explanation:
Given : Amount paid per hour = 12 $
12 $ are earned by Joanna by working for = 1 hour
Thus 432 $ are earned by Joanna by working for = [tex]\frac{1}{12}\times 432hour=36hours[/tex]
Thus the equation that can be used to determine the number of hours Joanna worked last week is [tex]12\times h=432[/tex]

Answer:
x = 1, y = 4, or x = -2, y = 1
Step-by-step explanation:
y = -x^2 + 5
-x + y = 3
Use substitution to solve for the equation
-x + (-x^2 + 5) = 3
-x^2 - x + 5 = 3 (simplifying)
-x^2 -x + 2 = 0 (simplifying)
(-x + 1)(x+2) = 0 (factoring)
-x + 1 = 0 or x + 2 = 0
x = 1, or x = -2
-x + y = 3
-(1) + y = 3, or -(-2) + y = 3
y = 4, or y = 1
just choose any one...
x = 1, y = 4
or x = -2, y = 1

The area of a rectangle is 20x2 - 27x- 8.
The length is 4x + 1. What is the width?
Answer:
5x - 8
Hope it helped :)
Answer:
5x-8
Step-by-step explanation:
im assuming you mean 20x^2 instead of 20x2 bc when you copy and paste it usually gets rid of the "^".
the area of a rectangle is length*width
so, to find the width, we have to solve the equation (4x+1)*width=20x^2-27x-8
the goal is to find (20x^2-27x-8)/(4x+1)
there is many ways to solve this: long division, synthetic division (easiest way)
but I'll just do guess and check
we know that the answer is in the form ax+b
we also know that b*1=-8 bc that's just how foiling works
We also know 4a=20
so, the answer is 5x-8
obviously you can check this answer if you are unsure of it being correct
(4x+1)(5x-8) = 20x^2-32x+5x-8 = 20x^2 - 27x - 8
so it does work

jo scroed 1324 points the entire season if she scored 17% of her points during the tournament how many points did she score during ht tournament
Answer:
225.08, which would just be 225.
Step-by-step explanation:
First, you multiply the percent, 17, times the total number of points, 1,324, which you should get 22,508. Then, divide that by 100, and you will get your answer 225.08. The reason you put it into the whole number, is because you can't score part of a point, so you always round down even if the number is in favor to round up. I hope this helps :)

9.Set R= {a, b, c}. Find the number of subsets in set R.
(4 Points)
Given:
The set is:
[tex]R=\{a,b,c\}[/tex]
To find:
The number of subsets in set R.
Solution:
Formula for number of subsets in a set of [tex]n[/tex] elements is
Number of subsets = [tex]2^n[/tex] ...(i)
We have,
[tex]R=\{a,b,c\}[/tex]
Here, the number of elements are 3. Putting [tex]n=3[/tex] in (i), we get
Number of subsets = [tex]2^3[/tex]
= [tex]8[/tex]
Therefore, the number of subsets is 8 and the subsets are [tex]\phi,\{a\},\{b\},\{c\},\{a,b\},\{a,c\},\{b,c\}[/tex] and [tex]\{a, b, c\}[/tex].

if XYZ ~ RST, find RS
Answer:
RS = 38

The value of the side of triangle RS is equal to 38.
What is the similarity?If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the sides of the triangle XYZ are, XY = 5x - 3, XZ = 60 and the sides of the triangle TR = 40, RS = 3x + 2.
The value of RS will be calculated as,
( 5x - 3 ) / ( 3x + 2 ) = ( 60 / 40 )
( 5x - 3 ) / ( 3x + 2 ) = ( 6 / 4 )
20x - 12 = 18x + 12
2x = 24
x = 12
RS = 3x + 2
RS = ( 3 x 12 ) + 2
RS = 36 + 2
RS = 38
Therefore, the value of the side of triangle RS is equal to 38.

×1.5
AB^2 = 4^2 + 3^2
AB^2 = 16 + 9
AB^2 = 25
AB = √25
AB = 5
A'B' = 5 × 1.5 = 7.5
The value of A'B' for the given congruent triangle will be 7.5.
What is congruence?If two figures are exactly the same in sense of their side of all things then they will be congruent.
If it is possible to superimpose one geometric figure on the other so that their entire surface coincides, that geometric figure is said to be congruent or to be in the relation of congruence.
As per the given congruent triangle,
In triangle ABC,
AB = √(3² + 4²) = 5
The ratio of the corresponding sides of the two triangles is the same.
A'B'/A'C' = AB/AC
A'B'/6 = 5/4
A'B' = 30/4 = 7.5
Hence "The value of A'B' for the given congruent triangle will be 7.5".

A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13 What is the: Total Surface Area of the Prism
Given:
A right prism has height 7½ and triangular bases with sides of length 5, 12, and 13.
To find:
The total surface area of the prism.
Solution:
We have,
Height of prism = 7½ = 7.5
Sides of triangular base are 5, 12, 13. These sides of Pythagorean triplets because
[tex]5^2+12^2=13^2[/tex]
[tex]25+144=169[/tex]
[tex]169=169[/tex]
So, the base of the prism is a right triangle.
Area of a triangle is
[tex]Area=\dfrac{1}{2}\times base \times height[/tex]
[tex]A_1=\dfrac{1}{2}\times 5\times 12[/tex]
[tex]A_1=30[/tex]
The area of the base is equal to the area of the top, i.e., [tex]A_2=30[/tex] sq units.
Perimeter of the base is
[tex]P=5+12+13[/tex]
[tex]P=30[/tex]
The curved surface area of the prism is
[tex]CSA=\text{Perimeter of the base}\times \text{Height of the prism}[/tex]
[tex]CSA=30\times 7.5[/tex]
[tex]CSA=225[/tex]
Now, the total area of the prism is
[tex]A=A_1+A_2+CSA[/tex]
[tex]A=30+30+225[/tex]
[tex]A=285[/tex]
Therefore, the total surface area of the triangular prism is 285 square units.
