If you spend 30 cents of 1 dollar, how much do you have left?
Answer:
70 cents
Step-by-step explanation:
lol mark as brainliest ig
Answer:
See explanation
Step-by-step explanation:
First, determine how many cents are in a dollar.
Now, it says you spent 30 cents, meaning you do not have that money anymore.
This means you must take "cents in a dollar - 30"
The answer you get is how much you have left! Feel free to check with me once you have calculated your answer!
Determine whether the graphs of the given equations are parallel, perpendicular, or neither.
Y= -2x+3
2x+y=7
A. Parallel
B. Perpendicular
C. Neither
Answer:
A
Step-by-step explanation:
Because the have the same slope.
The second equation solving for y is:
Y= -2x+7.
Both equations have the same slope of -2
Answer:
Parallel
Step-by-step explanation:
If lines have the same slope, then they are parallel. If lines have slopes that are opposite reciprocals of each other, then they are perpendicular. If neither one of those statements are true, then the answer is neither.
1) First, find the slope of the first equation. [tex]y = -2x + 3[/tex] is already in [tex]y = mx + b[/tex] format, or slope-intercept form. The [tex]m[/tex], or the coefficient of the x term, represents the slope. Thus, by looking at the equation, -2 is the slope of [tex]y = -2x + 3[/tex].
2) Second, find the slope of the second equation. [tex]2x + y = 7[/tex] is in standard format, but we can change it to slope-intercept format by isolating the y like so (just subtract both sides by 2x):
[tex]2x + y = 7 \\y = -2x + 7[/tex]
Now that it is in slope-intercept form, we can look at the coefficient of the x term, or [tex]m[/tex], to find the slope. That number is -2, thus the slope of [tex]2x + y = 7[/tex] is -2.
3) We found out that the slopes of both equations are -2. Thus, since they share the same slope, the lines are parallel.

PLEASE HELP, I need this test done and something not failed. I dont understand.
Answer:
XVW and WVT
Step-by-step explanation:
Two angles are supplementary angles when the sum of their measures is equaled to 180 degrees.
180 degrees = a line.
YVZ and WVU are Vertical Angles
YVZ and ZVT are not straight lines together.
XVW and WVU are on the same straight line but you have to add UVT in order to get 180.
XVW and WVT are the only ones that look like they can add up to 180 degrees.
XVW and WVT should be the answer, I really hope this helps!

Roberto must make his costume for his school play. He needs a piece of fabric that is 2 2/3 yards long and 1 1/2 yards wide. What is the piece of fabric Roberto needs?
Answer:
He will need 8.34 yards of fabric.
Step-by-step explanation:
Given that,
The length of the fabric, l = 2 2/3 yards = 8/3 yards
The width of the fabric, b = 1 1/2 yards = 3/2 yards
We need to find the piece of fabric Roberto needs. It is equal to the perimeter of the fabric such that,
[tex]P=2(l+b)\\\\P=2(\dfrac{8}{3}+\dfrac{3}{2})\\\\P=2\times \dfrac{25}{6}\\\\P=8.34\ \text{yards}[/tex]
So, he will need 8.34 yards of fabric.
Write the equation of this circle in standard form. A) (x - 2)2 + (y - 3)2 = 4 B) (x + 2)2 + (y + 3)2 = 4 (x - 2)2 + (y - 3)2 = 16 D) (x + 2)2 + (y + 3)2 = 16
Answer:
The answer is C.
Step-by-step explanation:
The equation of the circle (x - 2)² + (y - 3)² = 16 if the center of the circle is (2, 3) and the radius is 4 units option (C) is correct.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
It is given that:
The graph of the circle is given in the picture:
The center of the circle is (2, 3) and the radius of the circle is 4 units
As we know, the standard equation of the circle is:
(x - h)² + (y - k)² = r²
Here (h, k) and r is the center of the circle and the radius of the circle.
h = 2 and k = 3
r = 4 plug all the values in the equation:
(x - 2)² + (y - 3)² = 4²
(x - 2)² + (y - 3)² = 16
Thus, the equation of the circle (x - 2)² + (y - 3)² = 16 if the center of the circle is (2, 3) and the radius is 4 units option (C) is correct.

I buy a T.V for 10,000 and sell it at profit of 20%. how much do I get
Answer:
12,000
Step-by-step explanation:
Cost Price of T.V. = Rs. 10000
Profit percent = 20%
Profit = Profit% of C.P.
= 20 divided by 100 multiply by 1000
= Rs 2000
Selling price = C.P. + Profit
= 10000 + 2000 = 12000
Hence, the answer is Rs. 12,000 on selling the T.V.
Hope this helps you!

A bridge is 3911.1 meters long. Which of the following best describes the length of the bridge in kilometers?
Answer:
3.9111 km
Explanation:
The length in kilometers is equal to the meters divided by 1,000. So, if you divide 3911.1 by 1,000 that equals 3.911. You move the decimal point to the left 3 times based on the number of zeros.

solve by substitute. 9y+8=x. -2x+8y=-36
Answer:
Let's solve for x.
9y+8=x
Step 1: Flip the equation.
x=9y+8
Answer:
x=9y+8
Let's solve for x.
−2x+8y=−36
Step 1: Add -8y to both sides.
−2x + 8y + −8y = −36 + −8y
−2x = −8y − 36
Step 2: Divide both sides by -2.
−2x / −2 = −8y − 36 / −2
x=4y + 18
Answer:
x=4y + 18

Answer:
(26, 2)
x = 26
y = 2
Step-by-step explanation:
Given:
9y + 8 = x
-2x + 8y = -36
Substitute (9y + 8) for x in the second equation.
-2(9y + 8) + 8y = -36
Then distribute and solve.
-18y + (-16) + 8y = -36
Combine like terms.
-10y - 16 = -36
-10y = -20
y = 2
Solve for x by substituting the y value (2) into 9y + 8 = x.
9(2) + 8 = x
18 + 8 = x
x = 26
Therefore, the solution is (26, 2) in terms of (x, y).
Solve the equation.
1.5x + 6 = 18
21.57 x 0.12 =
Divided by a power of 10
Answer:
Answer vary :
0.25884
Step-by-step explanation:
honestly in my opinion that’s the answer.
1. 21.57 times 0.12 = 2.5884
then divide 2.5884 by the power of ten, wich is moving the decimal to left with how many zeros their are.
-0.25884
since in 10 their is only one 0 we moved the decimal only one time to the left.
and that’s how I came to that solution.
Write the decimal as a percent.
0.0046 = %
Answer:
0.46%
Step-by-step explanation:
0.0046*100%= 0.46%
