Please find missing side length!
Answer:
The missing side length is 24.98 units
Step-by-step explanation:
Given
The attached right-triangle
Required
The length of the missing length
Let the missing length be x.
Apply Pythagoras theorem
[tex]Hyp^2 = Opp^2 + Adj^2[/tex]
This gives
[tex]43^2 = 35^2 + x^2[/tex]
[tex]1849 = 1225 + x^2[/tex]
Collect like terms
[tex]x^2 = 1849 - 1225[/tex]
[tex]x^2 = 624[/tex]
Take square roots of both sides
[tex]x = \sqrt{624[/tex]
[tex]x = 24.98[/tex] --- approximated

A person invested $440 in an account growing at a rate allowing the money to double every 8 years. How long, to the nearest tenth of a year would it take for the value of the account to reach $2,860?
9514 1404 393
Answer:
21.6 years
Step-by-step explanation:
The first statement tells you the account balance can be modeled by ...
A = 440(2)^(t/8) . . . . . where t is in years
We want to find t when A = 2860
2860 = 440(2^(t/8))
6.5 = 2^(t/8) . . . . . . . . . . divide by 440
log(6.5) = (t/8)log(2) . . . . take logarithms
t = 8·log(6.5)/log(2) ≈ 21.604 . . . . . . divide by the coefficient of t; evaluate
It would take about 21.6 years for the value to reach $2,860.

Answer:
x = 29
Step-by-step explanation:
Given:
m<PQS = 107°
m<RQS = 49°
m<PQR = (2x)°
Required:
Value of x
Solution:
m<RQS + m<PQR = m<PQS (angle addition postulate)
Plug in the values
49 + 2x = 107
Subtract 49 from each side
2x = 107 - 49
2x = 58
Divide both sides by 2
x = 58/2
x = 29

The table shows a linear relationship between x and y.
Answer:
slope=-9/2
y int- 6
Step-by-step explanation:
okay lets take two points
-2,15 and -6,33
the slope is 33-15/ -6-(-2)= 18/-4=-9/2
equation is y=mx+b where m is slope and b is y intercept
so plugging values in we get
15=-2(-9/2)+b
15=9+b
b=6
what's 2x + 60 = 100?
Answer:

Lalasa and Yasmin are designing a triangular banner to hang in the school gymnasium. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, what will the area of the actual banner be? A 52.5 ft2 B 17.5 ft2 39.375 ft2 D 78.75 ft2
Find the actual Dimensions of the triangle.
Multiply the size of the triangle on paper by 1.5 feet per inch:
Width = 5 x 1.5 = 7.5 feet.
Height= 7 x 1.5 =10.5 feet
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.
Answer: 39.375 square feet.
The area of the actual banner is 39.375 feet²
What is scaling?
Scaling is used to increase or decrease the size of a figure so as to create an image.
Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:
Base = 5 in * 1.5 feet per in = 7.5 feet
Height = 7 in * 1.5 feet per in = 10.5 feet
Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²
The area of the actual banner is 39.375 feet²

Which relation symbol makes this number sentence true?
3/8 ___ 8/15
=
≠
Answer:
≠
Step-by-step explanation:
Sorry I just need 20 Characters
Answer:
≠
Step-by-step explanation:
Because 3/8 is 0.375, 8/15 is 0.53( with the 3 repeated). The decimal values aren't the same so the answer is that these 2 fractions are not equivalent.
