Answer: x = 7
Part A: y = (x)3- + 40
22 = 7 x 3- + 40
22 = 21- + 40
40 - 21 = 22
Part A= 22
Part B: x - 3(7) = 7(y) + x
40 + 37 + 34 + 31 + 28 + 25 + 22
Part B: 217

) A different rectangle has area 12a² and perimeter 14a
What are the dimensions of this rectangle?
Dimensions:
. by
Answer:
l = 4a and b = 3a
Step-by-step explanation:
Given that,
The area of the rectangle, A = 12a²
Perimeter, P = 14a
The area and perimeter of a rectangle are given by :
A = lb
12a² = lb ....(1)
P = 2(l+b)
14a = 2(l+b) ....(2)
We need to solve equations (1) and (2). After solving we find that.
l = 4a and b = 3a
Hence, the dimensions of this rectangle are 4a and 3a.

Find the perimeter of the semicircular region. Round your answer to the nearest hundredth.
6 in.
9514 1404 393
Answer:
30.85 in
Step-by-step explanation:
The circumference of a circle with a 6" radius is ...
C = 2πr
C = 2π(6 in)
Then the curved portion of a semicircle with that radius will have the length ...
1/2C = 1/2(2π)(6 in) = 6π in . . . . curved length
The straight portion of the boundary of this figure is simply twice the radius, so is ...
2×6 in = 12 in . . . . straight length
__
The perimeter is the sum of the curved and straight lengths:
P = (6π +12) in ≈ 30.8496 in ≈ 30.85 in . . . . figure perimeter
what does x and y =??????
Answer:
x=30. y=60
Step-by-step explanation:
DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.
What is the value of x in the figure shown below?
The value of X is 35 because the angle 35 measures the same as the angle X, hence their values are the same

the nutrition information on the cereal box says that a 1/2-cup serving provides 210 calories and 6 grams of dietary fiber. at that rate, find how many calories and grams of fiber are in a 1/3-cup serving
Answer:
140 Calories and 4 grams of dietary fiber per 1/3-cup serving.
Step-by-step explanation:
hi you can find this by first doubling the amounts for a 1/2 cup serving
so then it is equal to a full cup serving.
and then divide those by three,
that way it will be equal to 1/3 cup serving.
so
210*2= 420 (lol)
6*2= 12
now divide these numbers by 3
420/ 3 = 140
12/3= 4
so your answers are
140 Calories and 4 grams of dietary fiber per 1/3-cup serving.
I hope this helps! Good luck!

Answer:
b = 40km is the answer.
Step-by-step explanation:
a = 9km
b = ?
c = 41km
By using the Pythagoras theorem,
a² + b² = c²
9² + b² = 41²
81 + b² = 1681
b² = 1681 - 81
b² = 1600
b = 40km
∴ b = 40km is the length of the missing leg.
Which is bigger a population or a sample?
a - Population
b - Sample
c - They are both the same

10.) Find values of x and y for which ABCD must
be a parallelogram.
A x=2 y=4
B x=2 y=6
C x=2 y=16
D x=6 y=2
Answer:
B x=2 y=6
Step-by-step explanation:
For ABCD to be parallelogram, following conditions should be satisfied:
2x - 0 = x + 2 & 4y - 8 = y + 10
2x - 0 = x + 2
2x - x = 2
x = 2
4y - 8 = y + 10
4y - y = 10 + 8
3y = 18
y = 18/3
y = 6

Which features are present in this polar graph?
The features that is present in this polar graph is that A. Symmetry about the polar axis θ = 0.
What is true of the polar graph?The polar graph can be said to have a symmetry about the polar axis which means that theta or θ is equal to 0.
This is because the graph is symmetric about the x-axis. This means that all the lines of symmetry can be seen intersecting the graph at x = 0. This proves that there is indeed symmetry in the polar graph.
In conclusion, option A, θ = 0 is correct.

what is the slope for this graph ?
Answer:
um 6/1?
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
The slope of a line is the change in the line. It is often referred to as the ([tex]\frac{rise}{run}[/tex]), the slope of the line can be found using the following formula,
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
The graph of the given line gives one the points (7, 2), (9, 6). Substitute these points into the given formula and solve for the slope,

7) Rob and Amy are selling cheesecakes for a school fundraiser. Customers can buy New York
style cheesecakes and chocolate marble cheesecakes. Rob sold 11 New York style cheesecakes
and 7 chocolate marble cheesecakes for a total of $266. Amy sold 4 New York style cheesecakes
and 14 chocolate marble cheesecakes for a total of $280. What is the cost each of one New York
style cheesecake and one chocolate marble cheesecake?
9514 1404 393
Answer:
New York style: $14Chocolate Marble: $16Step-by-step explanation:
We can let n and c represent the costs of the New York style and the chocolate marble cheesecakes, respectively. Then the two sales are ...
11n +7c = 266 . . . . . . . Rob's sale
4n +14c = 280 . . . . . . Amy's sale
The ratio of coefficients of c is a "nice" number (2), so we can eliminate the c variable easily to solve this. Dividing the second equation by 2 and subtracting it from the first gives ...
(11n +7c) -(1/2)(4n +14c) = (266) -(1/2)(280)
9n = 126 . . . . . . simplify
n = 14 . . . . . . . . divide by 9
Filling this into the first equation, we have ...
11(14) +7c = 266
7c = 112 . . . . . . . . subtract 154
c = 16 . . . . . . . divide by 7
One New York style cheesecake costs $14; one chocolate marble cheesecake costs $16.
