Answer:
1) a right triangle
Step-by-step explanation:
One of the caractheristics of a right triangle, the one in which the sum of the two sides squared is the hypotenuse squared(Pytagorean Theorem), is also the the altitudes of a triangle meet at one of the triangle’s vertices. So 1) is the answer to this question.

the number of customers waiting inside a restaurant was 2 less than a third of those waiting inside. if three customers were waiting inside how many were outside
Answer:
15 customers were outside
Step-by-step explanation:
Represent customers inside with x and customers outside with y.
So, we have:
[tex]x = \frac{1}{3}y - 2[/tex] --- First Statement
[tex]x = 3[/tex] --- Second Statement
Required
Find y
Substitute 3 for x in [tex]x = \frac{1}{3}y - 2[/tex]
[tex]3 = \frac{1}{3}y - 2[/tex]
Add 2 to both sides
[tex]2 + 3 = \frac{1}{3}y - 2 + 2[/tex]
[tex]2 + 3 = \frac{1}{3}y[/tex]
[tex]5= \frac{1}{3}y[/tex]
Multiply both sides by 3
[tex]3 * 5= \frac{1}{3}y *3[/tex]
[tex]15 = y[/tex]
[tex]y = 15[/tex]
Hence; 15 customers were outside

The single equivalent discount rate of the trade discount 6/4/2 is:
Answer:
3/1
Step-by-step explanation:
Given the expression 6/4/2, we are to express as a single fraction.
6/4/2
= 6÷4/2
= 6×2/4
= 12/4
= 3/1
Hence the expression as a single fraction is 3/1

Answer:
The polynomial -8x2 + 54x + 140 can be factored as (x + 2)(-8x + 70).
The factor (x + 2) represents the final price per hot dog after increasing it from the starting price of $2, where x is the number of $1 increases in price.
The factor (-8x + 70) represents the average number of hot dogs sold based on the price increase. For every $1 increase in price, the number of hot dogs sold declines by 8. So, if the price increases by x dollars, the number of hot dogs sold declines by 8x. Since the number of hot dogs sold without the price increase is 70, the number of hot dogs after a price increase is -8x + 70.

Answer:
C. y + 3 = ¼(x + 4)
Step-by-step explanation:
✔️Find the slope of the given line:
Slope = ∆y/∆x = -(4/1) = -4
The line that is perpendicular to the given line on the graph would have a slope that is the negative reciprocal of -4.
Thus, the slope of the line that is perpendicular to the line on the graph would be ¼.
m = ¼.
Since the line passes through (-4, -3), to write the equation in point-slope form, substitute a = -4, b = -3, and m = ¼ into y - b = m(x - a)
Thus:
y - (-3) = ¼(x - (-4))
y + 3 = ¼(x + 4)

A. AA
B. SAS
C. SSS
D. Not similar
The triangles of the dimensions are not similar by any property of similarity. Thus option D is correct.
Concept of similarity : Two triangles can be similar by AAA, SAS, SSS property .
Given,
Two triangles with different side lengths.
Here,
The two triangles are similar if they have same shape , but can be of different sizes and corresponding sides are of same proportions.
Here,
Triangles are of same shape but the corresponding sides are not in same proportions.
∴ 8/5 = 10/6.25 ≠ 12/7
Therefore the two triangles are not similar.

A triangle is translated 4 units down and 8 units to the right
Which translation returns it to its original location?
O(x, y) - (x + 4, y - 8)
o (x, y) - (x - 8, y + 4)
O (x, y) - (x - 4, y + 8)
O(x, y) — (x + 8, y - 4)

It's the second on, 4 units up and 8 units to the left
Solve using substitution.
4x – 7y = -18
x = 6
Answer:
6
Step-by-step explanation:
4(6) - 7y = -18
24 - 7y = -18
-7y= -42
y= 6
Answer: y=6
Step-by-step explanation:
4(6)-7y=-18
24-7y=-18 subtract 24 on both sides
-7y=-42 **then divide -7 on both sides**
and the answer is y=6

Express the rate described.
James needs to work 65 hours every 3 weeks to meet the quota for his school internship.
Answer:
21.67 hours/ week
Step-by-step explanation:
Given
[tex]Hours = 65[/tex]
[tex]Weeks = 3[/tex]
Required
Determine the rate
The rate is calculated using:
[tex]Rate = \frac{Hours}{Weeks}[/tex]
Substitute values for hours and week
[tex]Rate = \frac{65}{3}[/tex]
[tex]Rate = 21.67[/tex]
This implies that the rate is 21.67 hours/ week

The expression (4a + b) – 3(2a + b) is equivalent to:
Answer:
-2a - 2b
Step-by-step explanation:
Question : (4a + b)-3(2a + b)
= 4a + b - 6a - 3b
= 4a - 6a + b - 3b
= -2a + (-2b)
= -2a -2b
If you need detail solution here ;
first + multiply both 4a and b
first -3 multiply both 2a and b and then -3×2a= -6a
-3×b = -3b
and it will be 4a + b -6a -3b,then collect like terms
4a - 6a + b -3b
= -2a +(-2b) in this part + tims - = -
= -2a - 2b

Hello can you tell me what the answer of this How many subets dose the set a have a= ( a,b,c,d)
Answer:
16 subsets
Step-by-step explanation:
To know the number of subsets that the set have, we will have to find the power of the set.
Given the set a = ( a,b,c,d)
P(a) = 2^n where;
n is the total number of element in the set
n = 4
p(a) = 2^4
P(a) = 16
Hence the set has 16 subsets
You are given that angle RST and angle TUR are right angles. What additional piece of info allows you to prove they are congruent
Answer:
the additional info required is - the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle.
Step-by-step explanation:
As given , RST and angle TUR are right angles.
So the triangles are right angle triangles.
If the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle, the two triangles are congruent.
So, the additional info required is - the hypotenuse and one leg of one right-angled triangle are equal to the corresponding hypotenuse and leg of another right-angled triangle.
