Answer:
x = 7
z = 85
Step-by-step explanation:
For x:
8x + 39 = 95
8x = 56
x = 7
For z:
95 + 95 + z + z = 360
190 + 2z = 360
2z = 170
z = 85
Check work:
DOES 85 + 85 + 95 + 95 = 360 ? Yes. Answer is correct.

i’m literally over here crying bc i can’t figure this out. if i don’t turn it in before an hour i get an F. PLEASE HELP. the question is “the diameter of the semicircle below is 12 yards. find the area and perimeter” you don’t have to do both numbers just pls let me know what one you solve. you can even only do area. i just rlly need help.
Answer:
Area = 346.2yd²
Perimeter = 72.1yd
Step-by-step explanation:
AREA
Split it into three shapes: (1) the semi-circle, (2) the triangle, and (3) the rectangle. Find the area of each and then add them together for the area of the whole shape.
Area₁ = πr² = (6²)π = 36π = 113.1 yd²
Area₂ = (1/2)bh = (1/2)(11.3)(14) = 79.1 yd²
Area₃ = lw = (11)(14) = 154 yd²
154 + 79.1 + 113.1=346.2yd²
PERIMETER
The perimeter consists of the length of the curve on the semi-circle, the top , the right side, the bottom, and the slanted line.
length of the curve on the semi-circle = half the cicumference of circle with radius 6 = (2π(6))/2 = 6π = 18.8
the top = 22.3
the right side = 14
the bottom = 11
the slanted line = the hypotenuse of triangle(2) - the diameter of circle(1) = (√(11.3²+14²))-12= (√(323.69))-12=18-12=6
18.8+22.3+14+11+6=72.1yd
Nathaniel, a meteorologist, keeps track of the amount of rain each year relative to the amount of rain in
2000. Two years of data are shown in the table below.
Year
Amount of rain relative to 2000 (in cm)
2004
27
2005
-49
Which one of the following inequalities correctly compares the relative amounts of rain?
Choose 1 answer:
27 <-49
-4927
Which one of the following descriptions is correct?
Choose 1 answer:
There was less rain in 2004 than in 2005.
there was less rain in 2005 than in 2004
Answer:
Both answers are the first option.
Step-by-step explanation:
Question 1: 27 is greater than -49, so that is why the first option for question one is correct.
Question 2:-49 is less than 27 so that is why 2005 had less rain compared to 2004.
The correct inequality comparison is 27 > -49.
The correct description is: There was less rain in 2005 than in 2004.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
When we compare the relative amounts of rain in the table, we see that the amount of rain in 2005 (-49 cm) is less than the amount of rain in 2004 (27 cm).
The correct inequality comparison is: 27 > -49
The minus sign in front of 49cm in 2005 indicates that the amount of rain is less than the amount of rain in 2000.
So, the correct description is: There was less rain in 2005 than in 2004.

Answer: 2 is the y intercept
Step-by-step explanation:
Slope is rise over run and in this problem our y intercept is 2 because it is defined as the y. Negate your 9 and put it over the y intercept to make into a fraction to represent slope. This makes it y = mx + b form now.
y = - 9/2x + 2

Find the value of X. geometry!! only answer if you know how please !
Answer:
x = 136
Step-by-step explanation:
This one is quite simple
The shape formed inside of the circle is a quadrilateral.
when a quadrilateral is formed inside of a circle opposite angles of the quadrilateral will add up to 180
we are given x's opposite angle so we can find x by subtracting the given angle's measure (44) from 180
so x = 180 - 44
180 - 44 = 136
hence, x = 136

Write a compound interest function to model the following situation. Then, find the balance after the given number of years. $16,000 invested at a rate of 1.2% compounded monthly;7 years
A. A=16,100 (1.001)^7t; $17,469
B. A=16,100 (1.1)^12t; $6,766,377,209
C. A=16,100(1.001)^12t; $17,510
D. A=16,000(0.001)^12t; $24,150
Answer:
The answer to this question is:
A = 16,100(1.001)12t; $17,510
Step-by-step explanation:
The model function for compound interest is: [tex](16000[1.001]^{12t})[/tex]
The balance after 7 years will be $17409.
How to calculate the compound interest if it is compounded monthly?Let, P = the principle amount
r = the rate of interest, compounded monthly
t = the time period
Therefore, the amount will be
[tex]= P(1 + \frac{r}{1200})^{12t}[/tex]
Given, the invested amount is $16000.
The rate of interest is 1.2%, compounded monthly.
Total duration of investment is 7 years.
Therefore, the model function of this compound interest is:
= [tex]= (16000[1 + \frac{1.2}{1200}]^{12t})\\= (16000[1 +0.001]^{12t})\\= (16000[1.001]^{12t})\\[/tex]
The amount will be
[tex]= (16000[1.001]^{12t})\\= (16000[1.001]^{84})\\= 17409[/tex]
Therefore, after 7 years, the amount will be $17409.

The area of a pasture is 4200 m and the perimeter is 260 m. What are the length and width of the pasture?
Answer:
70 m and 60 m
Step-by-step explanation:
The formula for the area of a rectangle is length ⋅ width.
The area of the pasture of 4200 meters.
70 ⋅ 60 = 4200.
The formula for the perimeter of a rectangle is side + side + side + side.
The perimeter of the rectangle is 260 meters.
70 + 60 + 70 + 60 = 260.
Therefore, the length and width of this pasture are 70 meters and 60 meters.

I need help with angles
Answer:
1. ∠CFD = 28°
2. ∠RPQ = 53°
Step-by-step explanation:
For the first one:
∠CFD and ∠DFE are angles on a straight line
Angles on a straight line add up to equal 180
That being said we can find the missing angle (∠CFD) by subtracting the given angle measure (152°) from 180
so ∠CFD = 180 - 152
180 - 152 = 28
Hence, ∠CFD = 28°
For the second one:
Complementary angles have a sum of 90°
If ∠RPQ and ∠SPR are complementary angles we can find the missing angle ( ∠RPQ in this case ) by subtract the given angle measure ( 37° ) from 90
so ∠RPQ = 90 - 37
90 - 37 = 53
Hence , ∠RPQ = 53°
