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.
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
Answers
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

Step-by-step explanation:
Answer:

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,
[tex]\frac{6 - 2}{9 - 7}[/tex]
Simplify,
[tex]=\frac{4}{2}[/tex]
[tex]=2[/tex]
If the outside diameter of a pipe is 1.25 ft and the inside diameter is 0.975 ft how thick is the pipe
Answers
Answer:
0.275
Step-by-step explanation:
1.25-0.975=0.275
Answer: .1375
See explanation:
1.25-0.975=.275
Now since this gives you the difference between the outside diameter and the inside diameter it actual gives you 2 times the wall thickness. So we need to divide that by 2.
.275/2=.1375
So the wall thickness of the pipe is .1375

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
Answers
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!

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?
Answers
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.

Answers
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 are the dimensions of this rectangle?
Dimensions:
. by
Answers
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.
