If the triangles are similar, then the value of x is (blank) and the value of y is (blank)
I REALLY NEED HELP PLZZZ
Answers
Answer:
([tex]x[/tex], [tex]y[/tex]) = (30, 16)
Step-by-step explanation:
First find the similarity
Since you know the legnth of the hypotenuse (the longest one) for both traingles, you can find the similarity by dividing the longer by the shorter:
50 ÷ 20 = 2.5
The similarity between the 2 triangles is 2.5.
Now find the length of [tex]x[/tex] on the longer one, use the shorter one's length and the similarity:
12 × 2.5 = 30
So the length of [tex]x[/tex] is equal to 30
Now lets find [tex]y[/tex], lets use the length of the larger triangle this time and divide the length of the longer leg (there are 2 legs in every triangle, if you don't know the hypotenus's length, use the pythagorean theorem) and divide it by the similarity:
40 ÷ 2.5 = 16
[tex]y[/tex] = 16
WooHoo! ([tex]x[/tex], [tex]y[/tex]) = (30, 16)

Explain the difference between a concave polygon and a convex polygon. (please please pleaseeeeee help)
Answers
Answer:
Every polygon is either convex or concave. The difference between convex and concave polygons lies in the measures of their angles. For a polygon to be convex, all of its interior angles must be less than 180 degrees. Otherwise, the polygon is concave.
Find an
equation for the perpendicular bisector of the line segment whose endpoints
e (-3, -8) and (5,-4).
are
Answers
Answer:
[tex]y=-2x-4[/tex]
Step-by-step explanation:
Perpendicular Bisector
The bisector of a segment defined by points (x1,y1) and (x2,y2) must pass by the midpoint of the segment.
The midpoint (xm,ym) is calculated as follows:
[tex]\displaystyle x_m=\frac{x_1+x_2}{2}[/tex]
[tex]\displaystyle y_m=\frac{y_1+y_2}{2}[/tex]
The endpoints of the segment are (-3,-8) and (5,-4), thus the midpoint M is:
[tex]\displaystyle x_m=\frac{-3+5}{2}=1[/tex]
[tex]\displaystyle y_m=\frac{-8-4}{2}=-6[/tex]
Midpoint: M(1,-6)
Let's find the slope of the given segment. The slope can be calculated with the formula:
[tex]\displaystyle m_1=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\displaystyle m_1=\frac{-4+8}{5+3}=\frac{1}{2}[/tex]
If the bisector is also perpendicular, its slope m2 and the slope of the segment m1 must comply:
[tex]m_1.m_2=-1[/tex]
Solving for m2:
[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{\frac{1}{2}}=-2[/tex]
Once we have the slope -2 and the point through which our line must pass (1,-6), we compute the equation in its point-slope form:
[tex]y-y_o=m(x-x_o)[/tex]
[tex]y-(-6)=-2(x-1)[/tex]
Operating
[tex]y+6=-2(x-1)[/tex]
[tex]y+6=-2x+2[/tex]
Rearranging
[tex]\boxed{y=-2x-4}[/tex]

Answer:
5) y = -8x -4
6) y = 2x + 3
Step-by-step explanation:
Slope is rise over run. For the first problem, you went down 8 and over 1 to your next point. Going down means you have a negative slope. -8/1 is 8. Your y intercept is where the line meets the y axis. The line meets the y axis at -4.
The line meets a new point every time it goes over 1 and up 2. Rise over run means 2/1. The line goes up so the slope is positive. The line meets the y axis at 3

Which is the best estimate of 26 × 604?
Answers
Answer:
The answer is actually 18,000 because for 26 your rounding the nearest ten and for 604 you rounding the nearest hundred so it is 30 x 600 = 18,000
Step-by-step explanation:
The best estimation of 26 × 604 is 18000.
What is Number system?A number system is defined as a system of writing to express numbers.
We need to find estimate of 26 × 604
Approximating a quantity to the required accuracy is known as estimation. This estimation we can do by rounding off the numbers involved in the calculation and get a rough answer.
Now let us round off the number 26 to the nearest tenths.
26 is rounded to 30.
604 is round off to the nearest hundredth which is 600.
Now let us multiply 30 with 600 to get the estimated value of 26 × 604.
30×600
18000
Hence the best estimation of 26 × 604 is 18000.

-8, -6, -4, -2
Step-by-step explanation:
This is the only sequence that is using constant repetition of addition, either adding positive numbers or adding negative numbers (the same positive or negative number). This one that you answered is always adding 2 from the prior number, so -6 = -8+2, -4=-6+2, and so on.
The first one is an odd combo where you add and subtract different values different signs each time, it is not constant addition of the same number.
The second one is multiplication which is not arithmetic, so that means it is constantly being multiplied by 2 each time.

A pet store sells mice, reptiles, and birds.

A. Buying a mouse and buying a bird are mutually exclusive events.
B. The probability that a customer buys neither a mouse nor a bird is
25%.
C. The probability that a customer buys both a mouse and a bird is
25%.
D. The probability that a customer buys either a mouse or a bird is
25%.
Answers
The correct answer is: The probability that a customer buys either a mouse or a bird is 25%.
What is probability?Probability is a measure of the likelihood of an event to occur. Many events cannot be predicted with total certainty. We can predict only the chance of an event to occur i.e. how likely they are to happen, using it.
Given that, a pet store sells mice, reptiles, and birds,
Let event A = A customer buys a mouse.
Let event B = A customer buys a bird.
We need to tell that,
What does P(A or B) = 0.25 mean in terms of this problem,
So, here the statement given is saying that the 0.25 is the probability that a customer will buy either a mouse or bird,
Hence, the correct answer is: The probability that a customer buys either a mouse or a bird is 25%.
