Answer:
x = 18
Step-by-step explanation:
The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{80}{80+2x}[/tex] = [tex]\frac{60}{60+27}[/tex] = [tex]\frac{60}{87}[/tex] ( cross- multiply )
60(80 + 2x) = 6960 ← divide both sides by 60
80 + 2x = 116 ( subtract 80 from both sides )
2x = 36 ( divide both sides by 2 )
x = 18

Which measurements are necessary for determining both the speed and
velocity of a moving object?
A. Distance, time, and direction
B. Direction, displacement, and distance
C. Distance, direction, and acceleration
D. Direction, time, acceleration
Answers
Answer:
b i am pretty sure
Step-by-step explanation:
Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object
What is Speed?Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object's movement.
The measurements which are necessary for determining both the speed and velocity of a moving object.
Speed=Distance/Time
To calculate speed we need to know the distance and time.
Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference
Velocity=Displacement / Time
Hence Direction, displacement, and distance are the measurements are necessary for determining both the speed and velocity of a moving object

which numbers in the list are less than -0.94?
Answers
Answer:
The answer is B
The numbers -2.23 [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have a number list:
-15/16, 0.24, -2.23, 97%, [tex]-2\frac{2}{5}[/tex], -0.95
We can write these numbers such as:
-0.9375, 0.24, -2.23, 0.97, -2.4, -0.95
Now comparing the each number with -0.94
-0.9375 > -0.94
0.24 > -0.94
-2.23 < -0.94
0.97 > -0.94
[tex]-2\frac{2}{5}[/tex] or -2.4 < -0.94
-0.95 < -0.94
Thus, the numbers -2.23 [tex]-2\frac{2}{5}[/tex], and -0.95 are numbers that are less than -0.94 option (B) is correct.

Hhhhhhhhhhhhhhhhhhhhhh
Answers
Answer:
-22 + (-16)= -38
Step-by-step explanation:
Answer
-38
Explanation
This is the expression given.
-22+(-16)
Adding a negative number to something is the same thing as subtracting the number.
-22-16
To subtract two negative numbers, you are technically adding the numbers and putting a negative sign.
22+16=38
And put a negative sign in front of that.
So the answer would be -38.

For the first option, the average is
= $55.50 ÷ 3 shirts
= $18.50 per shirt
For the second option, the average is
= $79.99 ÷ 5 shirts
= $15.998 per shirt

"Six more than one third of a number is
three."
Answers
Answer:
options? or answer choices?
Step-by-step explanation:
:-
Let the number be x
One third of a number = x =
Six more than one third of a number = + 6
Their sum = 3
Accoeding to the question,
+ 6 = 3
Multiplying both sides by 3 we get,
x + 18 = 9
Moving constant to the right, we get,
x = 9 - 18
By calculation, we get,
x = -9
∴ The number is -9
Verification :-
+ 6 = 3
=> + 6 = 3
=> -3 + 6 = 3
=> 3 = 3
LHS = RHS ✔✔
∴ The number is -9

1. Carly buys a pair of jeans. The store marks them down 25%. They were originally $59.80 and she has to pay a tax of 8%. What is the price of the jeans after the discount and then tax is applied?
Answers
Hey there!
The answer is $48.44
We can solve this by first finding how much the discount is.
0.25 x 59.80
14.95
The amount of the discount is 14.95, so we then take the discount off.
59.80 - 14.95
44.85
Then, we find the amount of tax.
.08 x 44.85
3.588 (round to nearest cent = 3.59)
Then, add the price of the tax onto the price of the jeans.
3.59 + 44.85
48.44
Hope this helps! Good luck!

Let's take this problem step-by-step:
First step: we note the exponential power is negative⇒ thus we move the whole thing to the denominator
[tex]x^{-\frac{5}{3} } =\frac{1}{x^{\frac{5}{3} } }[/tex]
the Second step, now we need to figure out the fraction that the is an exponent of x⇒ '3' which is on the denominator of the fraction
⇒represents the '3rd' root of x or the cubic root of x
⇒ 5 which is the numerator of the fraction is
⇒represents the 5th power of x or x to the power of 5
Result: [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]
Answer: The second choice or [tex]\frac{1}{\sqrt[3]{x^5} }[/tex]
