Answer:
50
Step-by-step explanation:
Since it's a right angle, it's automadically 90 degrees. Add 29 + 13 which gives you 42. 90 - 42 gives you 48. Rounded to the nearest 10th is 50. Here's what I explained in numerical form:
29 + 13 = 42
90 - 42 = 48
Five or more raise the score. For or less turn to zero:

A designer decides to create a larger scale model of a smart phone so that his team can work more easily on the design. The length of the screen of his model is 60 centimeters, which is 2.5 times longer than it is wide. The designer asked his team to build the screen of the actual phone with a width of 6 centimeters. What is the scale factor of the model phone to the actual phone?
Answers
Answer:
The length of the model is 250% of the width and is 60 centimeters, and the width of the actual phone is 6 so it has a scale factor of 4:1.

The line y = mx + c passes through the points (-2, 1) and (4,4).
Write down a pair of simultaneous equations involving m and c.
Solve the simultaneous equations.
Answers
Answer:
Step-by-step explanation:
Insert x for -2 & 4 and y for 1 & 4
1=-2m+c, 4=4m+c
solve the equation, m=1/2, c=2
Answer:
y = 1/2m + 2
Step-by-step explanation:
1 = -2m + c (1)
4 = 4m + c (2)
2 = -4m + 2c (1*)
(1*) + (2) = 6 = 3c
c = 2
y = mx + 2
4 = 4m + 2
2 = 4m
m = 1/2
so y = 1/2m + 2

Based on the information, the value of the piano after 16 years is $140.74.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Using this formula to find the value of the piano, v, after t years.
CP = Principal(1-rate)[tex]^t[/tex]
Where:
Principal=$5,000
Rate=20%
Number of year = 16 years
Let plug in the formula;
=5,000(1-0.20)^16
=5,000(.80)^16
=$140.737
= $140.74 (Approximately)
Hence, the value of the piano after 16 years is; $140.74.

There are two mystery numbers. The sum of 2 times the first number and 5 times the second number is -5. The sum of 3 times the first number and 10 times the second number is -5. What are the two numbers?
Answers
Answer:
the two numbers are -5 and 1
Step-by-step explanation:
Let x and y be the first number and second number respectively.
According to the question, we can find 2 equations:
2x + 5y = -5
3x + 10y = -5
On solving,
x = -5
y = 1
Answer:
X=-5,Y=1
Step-by-step explanation:
First equation: 2X+5Y=-5
Second equation:3X+10Y=-5
If we subtract the first from the second equation
(3X+10Y)-(2X+5Y)= 0 so, X+5Y= 0
So X= -5Y .then substitute in the second equation
So ,3(-5Y)+10Y= -5 , therefore -15Y + 10Y=-5 so, -5Y=-5 which means that Y=1
Then substitute with that in the first equation so 2X+5= -5
2X= -10 therefore X=-5

Answer:
y = 1500(1.079)^t
Step-by-step explanation:
Here, we want to write an exponential function
Mathematically, we have this generally as;
FV = IV( 1 + r)^t
where FV is future value which is y in this case
IV is the initial value which is 1,500 kn^2 in this case
r is the rate of change which is 7.9%
7.9/100 = 0.079
t is the time difference
so we have the equation as;
y = 1500(1 + 0.079)^t
y = 1500(1.079)^t
A fitness trainer sets the incline on a
treadmill to 7º. The walking surface is 5
feet (60 inches) long. Approximately how
many inches did the trainer raise the
end of the treadmill from the floor?
Answers
Answer:
Step-by-step explanation:
sin Ф equal the opposite leg of the triangle dividend by the hypotenuse
sin Ф = opp / hyp
the problem gave you the Ф (the angle 7°)
and the length of the hypotenuse (the walking surface 60 inches)
You want to use the inches since the question wants to know how many inches off the floor is the end of the walking surface
sin 7 = opp / 60 solve for opp
60 × sin(7) = opp use your calculator, I don't have one handy
a polygon has perimeter 15 units.it is dilated with a scale factor of 3/5.what is the perimeter of its image
Answers
Given what we know, we can confirm that the perimeter of the image is 9 units.
Perimeter and Scale factor.To calculate the perimeter of a shape, we must add the length of all of its sides. When we dilate a shape, we multiply each of its sides by our scale factor.Our scale factor is [tex]\frac{3}{5}[/tex], which corresponds to 0.6 in decimal form Taking the sum of 15 as the perimeter of the preimage and multiplying by 0.6 gives us the perimeter of the image which is 9 units.Therefore, given that [tex]15units * \frac{3}{5} = 9 units[/tex], we can confirm that the perimeter of the image is 9 units.

the area of a triangle is 9 because 4.24 times 4.24 equals 17.9776 estimated is 18 divided by 2 is 9 times 4 is 36. Now we divide 36 by 2 so we know what the area of the two trapezoids so we know the top and the bottom which is 18. The area of the square in between the triangles is 4.24 times 6 which is 25.22 estimated is 26. Now we add 26 with 18 which is 34. Now we have to find the area of the rectangle to do this we need to multiply 7.24 and 2 we need to do this so we know the length of the rectangle which is 14.48 estimated is 14. Now that we know the length we multiply it with the height which is 6, 14 times 6 equals 84.
84 is the rectangles area and the area for the trapezoids is 36.
84 plus 18 plus 18 equals 120 squared
