Answer:
The measure of the third angle must be 104°
Step-by-step explanation:
Interior Angles of a Triangle
In any given triangle, the sum of its interior angles is 180°.
We are given the angles x=51° and y=25°. To find the third angle, z, we set up the equation:
x + y + z = 180
Solving for z:
z = 180 - x - y
Substituting:
z = 180 - 51 - 25
z = 104°
The measure of the third angle must be 104°

What are the coordinates of vertex B' if the figure is rotated
90° counterclockwise about the origin?
Answer:
Answer: B'(-5,2)
Step-by-step explanation:
Rotations
When rotating a point B(x,y) 90 degrees counterclockwise about the origin it maps to an image point B'(-y,x).
The image shows a figure formed by points ABCD. The coordinates of B are B(2,5).
This point will be rotated 90 degrees counterclockwise about the origin, thus the coordinates of the image point B' are B'(-5,2).
Answer: B'(-5,2)

Which graph represents an exponential function?
Answer:
b
Step-by-step explanation:
The second graph, which represents Table B, represents an exponential function.
What is an exponential function?Mathematical functions with exponents include exponential functions. f(x) = bˣ, where b > 0 and b 1, is a fundamental exponential function.
Let table A represents the first graph.
x: 0, -1, 1, 2, -2, 3, -3.
y: 0, -1, -1, -4, -4, -6, -6.
And table B represents the second graph.
x:-4, -3,-2.75, -2.
y: 2, 4, 6, 10
To determine which graph represents an exponential function, we need to recall the properties of exponential functions. An exponential function is a function of the form y = a^x, where a is a constant greater than 0 and not equal to 1.
Looking at table A, we can see that the y-values do not appear to follow an exponential pattern. For example, the y-values for x = 1 and x = -1 are both -1, but the y-value for x = 2 is -4. This is not consistent with the pattern of an exponential function.
Looking at table B, we can see that the y-values do appear to follow an exponential pattern. The y-values increase rapidly as x increases, which is consistent with the pattern of an exponential function. To confirm this, we can calculate the ratio of consecutive y-values:
For x = -4 and x = -3, y increases by a factor of 4/2 = 2.
For x = -3 and x = -2.75, y increases by a factor of 6/4 = 1.5.
For x = -2.75 and x = -2, y increases by a factor of 10/6 = 1.67.
These ratios are not exactly the same, but they are approximately equal to each other. This is consistent with the pattern of an exponential function, where the ratio of consecutive y-values is constant.
Therefore, the second graph, which represents Table B, represents an exponential function.

Step-by-step explanation:
Vertical lines are always undefined because if your answer has to be divided by zero, the answer is an undefined operation.
Horizontal lines always have the slope of zero!
Which expression is NOT equivalent to 2m 3 +4?
A. 4 + 2m
B. 3m2+4
C. 2(m+2)
D. m+m2+3+1
Answer:
I believe the answer is B,
explanation:
Well, the others are exactly alike, the first answer is just the two numbers flipped, the third is where multiplication is needed, so (2 x m^3) + (2 x 2) = 2m^3 + 4. and the final one is m^3 plus itself which equals to 2m^3 + 4.

Yesterday I ran 9.6 miles at an average speed of 0.4 miles per 5 minutes. How long did it take me to run the 96 miles?
Answer:
Step-by-step explanation:
This is how we do it in college, I hope I can be of some help.
First, you multiple 9.6 miles with 5 minutes. Then, you divide your answer with 0.4 miles. Next, you cancel the two mile units because of division and then be left with 120 minutes.
9.6 miles x 5 minutes = 48 miles x minute = 120 minutes
0.4 miles 0.4 miles
Here is a formula for the amount of water needed to cook rice.
w = 1.5r + 0.5
w is the number of cups of water needed.
r is the number of cups of rice to be cooked.
(a) How many cups of water are needed to cook 7 cups of rice?
(b) How many cups of rice can be cooked with 20 cups of water?
Step-by-step explanation:
So w =water.
1 cup of water is equal to 1.5 times the volume of rice +0.5
so it'd be (11x1.5) + 0.5 for part A and for part B so you'd need to rearrange the equation which i'm not confident on .
W= (1.5 x11)+0.5
W=17
29=(1.5 x r) + 0.5
28.5=1.5r
19= r

the simple interest on a sum of money for 2 years at 12% per annum is rupees 1380
(i) find the sum of money
(ii) the compound interest on this sum for 1 year payable half-yearly at the same rate.
Answer:
5750
710.7
Step-by-step explanation:
Simple interest = principal. * rate * time
Principal (p) = sum of money
1380 = p * 0.12 * 2
1380 = 0.24p
p = 1380 / 0.24
p = 5750 rupees.
The compound interest :
A = P(1 + r/n)^nt
A = final amount
n = number of compounding times per period
t = period
A = 5750(1 + 0.12/2)^2*1
A = 5750(1 + 0.06)^2
A = 5750(1.06)^2
A = 5750 * 1.1236
A = 6460.7
Hence, compound interest is :
Final amount - principal
6460.7 - 5750
= 710.7 rupees

What is 35% of 220? A. .77 B. 7.7 C. 77 D. 770
Answer:
77
Step-by-step explanation:
35% of 220 is equivalent to 77.
What is function?A function is a relation between a dependent and independent variable.
Mathematically, we can write → y = f(x) = ax + b.
Given is to find 35% of 220.
Let 35% of 220 be {x}. Then, we can write -
{x} = 35/100 x 220
{x} = 35/10 x 22
{x} = 35 x 2.2
{x} = 77
Therefore, 35% of 220 is equivalent to 77.
