Step-by-step explanation:
Priya says these polygons are similar because their side lengths are the same. Clare says "these explain polygons are not similar because the angles are different." Do you agree with either priya or Clare explain your reasoning rhombus
Answer:
Clare is correct
Step-by-step explanation:
For two shapes to be congruent, the shape and size have to be the same. In other words they ate have to equal length in size and also equal angles(same shape hence equal angles). Therefore Clare is correct since only have equal length in sides does not qualify the polygon to be congruent or similar like Priya claims
Express: 50 minutes 18 seconds as percent of 2 hours.
Answer:
For me
Step-by-step explanation:
50 minutes to seconds=50×60=3000
18 minutes remains the same
3000+18=3018

What is the y-intercept of this graph
how do you find the missing variables in this problem please help
Answer:
x = 55, y = 70, z = 125
Step-by-step explanation:
125 and x are adjacent angles and are supplementary, then
x = 180 - 125 = 55
The triangle is isosceles ( 2 congruent sides ) thus the base angles are congruent, both 55
The sum of the 3 angles in the triangle = 180° , thus
y = 180 - (55 + 55) = 180 - 110 = 70
55 and z are adjacent and supplementary, so
z = 180 - 55 = 125
Answers:
x = 55
y = 70
z = 125
============================================================
Explanation:
The tick marks indicate those two lines are the same length. We have an isosceles triangle. One base angle is x. The other missing base angle is also x, which is adjacent to angle z. The base angles of any isosceles triangle are always congruent.
Since the 125 and x degree angle form a straight line, they must add to 180
x+125 = 180
x = 180-125
x = 55
We can use this to find y
x+x+y = 180 .... three angles of any triangle always add to 180
2x+y = 180
2(55)+y = 180 .... plug in x = 55
110+y = 180
y = 180-110
y = 70
And,
x+z = 180
55+z = 180 ... plug in x = 55
z = 180-55
z = 125

Step-by-step explanation:
Angles DEC and DFC are both 90°, therefore DC is the diameter of the circle.
That makes angle DBC = 90° as well, so x = 90.
px+c=n-x solve for x
the answer is
[tex]x = \frac{n - c}{p + 1} [/tex]
Step-by-step explanation:
add x to both sides of the equation
subtract c from both sides of the equation
factor x out of px+x
divide each term by p+1 and simplify and that how you get your answer.
Triangle JKL is dilated with the origin as the center of dilation to create J’K’L’.
Which rule best represents the dilation that has been applied to triangle JKL to create triangle J’K’L’?
Answer:
The answer is D
Step-by-step explanation:
The rule best represents the dilation that has been applied to triangle JKL to create triangle J’K’L’ is (x, y) → (x + 4.5, y + 3).
Option B is the correct answer.
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
From the graph,
J = (-2, 4)
K = (6, 4)
L = (8, -4)
And,
J' = (-3.5, 7)
K' = (10.5, 7)
L' = (14, -7)
Now,
If we apply the dilation:
(x, y) → (x + 4.5, y + 3) on JKL
We get,
J' = (-3.5, 7)
K' = (10.5, 7)
L' = (14, -7)
Thus,
The rule best represents the dilation that has been applied to triangle JKL to create triangle J’K’L’ is (x, y) → (x + 4.5, y + 3).

It costs $15 to attend a golf clinic with a local pro. Buckets of balls for practice during the clinic cost $4 each. How many buckets can you buy at the clinic if you have $36 to spend? Show Your Work You have responded to 10 of 14 questions. Submit multidie submissions allowed
Answer:
5 buckets
Step-by-step explanation:
If you have 36 dollars then you would subtract the amount it costs to get into the park:
$36 - $15 = $21
Then, you divide by 4 to see the maximum amount of buckets you can get:
$21/4 = 5 buckets that will be the maximum amount you can get

I finished question 1 but I could use some help on the others
Answer:
With the first four questions, all you need to do is find a value of x that gives you a zero value in any one of those brackets. Let's do it.
You said you finished 1, so let's skip it.
I can't give you a full answer for question 2, because you didn't capture the entire expression in the screenshot. I can see that the values 3 and 0.125 would give zero values, but I can't tell you the last.
For question three, we need to find x values where either 9x + 3 = 0, or x² - 9 = 0. There are three values that meet those conditions. You can solve it just by assigning a zero value and solving for x:
[tex]9x + 3 = 0\\3x + 1 = 0\\3x = -1\\x = -1/3[/tex]
For the second term actually has two solutions, because a squaring a number also causes negatives to be converted to positives. Another way of seeing this is to notice that the second term is actually a difference of squares:
[tex]p(x) = (9x + 3)(x^2 - 9)\\= (9x + 3)(x + 3)(x - 3)[/tex]
so in this case x could be -1/3, -3, or 3 to give a zero value.
For question four, you can only get a zero if you use imaginary numbers, as no real number can be squared to give you a negative. So the only answers to that are 5i, or -5i.
With questions five six seven and eight, we just need to make exceptions for zero denominators, so:
For question 5, you can x can be any real number except -4, 2 and 7
For 6, x can be anything but 3, 1/8th or 5
for 7, We again have that difference of squares, so the actual denominator is (9x + 3)(x + 9)(x - 9), meaning x can be anything but -1/3, -9, or 9
And finally for question 8, we again have a squaring, meaning that only an imaginary number will cause division by zero, meaning x can't be 5i or -5i.

The Answer:
= Your mom
Answer:
n = 4
Step-by-step explanation:
Add the powers of 3
4 -5 -3 = - 4
Now these make just 1 power that you have to deal with.
3^-4
and that equates to 1/3 ^ n = 3^ -n
So what is the answer?
3^-4 = 3^-n
Since the bases are the same, the powers can be equated.
- 4 = - n
divide by - 1 to get 4 = n

Deepti went to school for 216 days in a full year. If her attendance is 90%, find the
number of days on which the school was opened.
Answer:
240 days
Step-by-step explanation:
Because she went 216 days but its 90% of the school year. we don't know how much days are actually in the school year so we do 90÷100x we had added a x to the 100 because of that. that equals 216 days. X equals 240 days. By 240=100% x=90% 240 divided
Tell whether the ordered pair (−1, 4) is a solution of the system.
Answer:
(-1,4) is a solution to the system.
Step-by-step explanation:
For this problem, we can simply identify if this point is a solution by verifying the plugged in point values allow the left hand side to equal the right hand side.
(1) -2x - 3y = -10
-2(-1) - 3(4) ?= -10
2 - 12 ?= -10
-10 == -10
(2) -3x + y = 7
-3(-1) + (4) ?= 7
3 + 4 ?= 7
7 == 7
Since both equations are satisfied by this point, then we can say the point (-1,4) is a solution to the system. Additionally, this means this is a crossing point of the system of equations.
Cheers.
