Answer:
31 , 59
Step-by-step explanation:
a = b +28
a + b = 90 {Complementary}
b + 28 + b = 90 {Combine like terms}
2b + 28 = 90 {Subtract 28 form both sides}
2b = 90 - 28
2b = 62 {Divide both sides by 2}
b = 62/2
b = 31
a = 31 + 28
a = 59

Find the shaded area of each figure, round your answer to one decimal place if necessary
Step-by-step explanation:
radius of circle = 5 yd ------ ( given )
height of triangle = 16 yd --- ( given )
base of triangle = 16 yd ----- ( given )
area of triangle = 1/2 × base × height
= 1/2 × 16 × 16
= 128 yd²
area of circle = π × radius²
= 3.14 × 5 × 5 --- ( π = 3.14 )
= 78.5 yd²
---------------------------------------area of shaded portion = area of triangle - area of circle
area of shaded portion= 128 yd²-78.5 yd²

Step-by-step explanation:
Can a triangle have two obtuse angles? please Justify your answer.
Answer:
No, a triangle cannot have 2 obtuse angles. The definition of an obtuse angle is an angle with a measure that is greater than 90°.
Step-by-step explanation:
Answer:
No, because if the triangle have two obtuse angles i.e., more than 90° angle, then the sum of all three angles of a triangle will not be equal to 180°.

Answer: Angle B is 27 degrees
Step-by-step explanation:
All angles in a triangle must add up to 180 degrees so if two angles 63 and 90 add up to 153 then the last number added to 153 (x+153)=180 so 27 degrees
Answer:
Angle B is 27°

in the graph below what is the unit rate ken paid to rent a go kart create a table to help finding the unit rate
The graph is missing, so i have attached it.
Answer:
$0.40 per minute
Step-by-step explanation:
From the attached graph, we can see that it is a linear graph.
Thus, to find the unit rate paid by Ken, we will calculate the slope by picking two coordinate points with thick dots on the blue and calculating it.
Point 1 = (15, 6)
Point 2 = (35, 14)
Slope = (y2 - y1)/(x2 - x1)
Slope = (14 - 6)/(35 - 15)
Slope = 8/20
Slope = $0.40 per minute
What is the equation of the line (0, 0) (3, -9)
Answer:
y= -3x
Step-by-step explanation:
Find the slope
-9-0/3-0 = -9/3
Simplify = -3
Plug into point-slope formula
y-y1=m(x-x1)
y-0=-3(x-0)
y= -3x

what is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Original Cost = $14
Tax = 7%
So, Price after tax = 14 + 7% of 14
= 14 + 0.98
= $14.98
and, after 18% tip = 14 + 18% of 14
= $16.52
Hence, the tax is $0.98 and tip is $2.52

y=1x-1.
...............................................................................................................................................
2: The equation of the line that has a slope of 1 and a y-intercept of -3 is:
y=1x-3.
Step-by-step explanation: I graphed it
1: You want to find the equation for a line that has a slope of 1 and a y-intercept of -1.
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
All you really have to do here is
replace m with 1, which is the slope you gave, and
replace b with -1, the y-intercept you gave,
in the equation y=mx+b.
The equation of the line that has a slope of 1 and a y-intercept of -1 is:
y=1x-1.

Given:
Number of spheres = 2
Number of prisms = 3
Number of pyramids = 5
To find:
The probability that a pyramid will be selected.
Solution:
We have,
Favorable outcomes = Number of pyramids
= 5
Total outcomes = Total number of figures
= [tex]2+3+5[/tex]
= [tex]10[/tex]
Now, the required probability is:
[tex]\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}[/tex]
[tex]\text{Probability}=\dfrac{5}{10}[/tex]
[tex]\text{Probability}=0.5[/tex]
Therefore, the probability that a pyramid will be selected is 0.5.

with respect to the question, 4 is the y-intercept
we have this point as (0,4)
To get the x intercept, we will need to substitute 0 for the value of y
So, we have ;
0 = -x + 4
x = 4
The x-intercept too is 4
This is the point (4,0)
So by joining the points (0,4) and (4,0);
we have successfully graphed the line
