Answer:
The total angle is 90° (A quadrant)
x+10 + 30 =90
x= 90-40
x=50°
Answer:
x = 50
Step-by-step explanation:
From the diagram, we know that angle (x + 10)° and angle 30° are complementary angles (they add up to 90°). From this information, we can create the following equation.
(x + 10)° + 30° = 90°
x° + 10° = 90° - 30°
x° = 60° - 10°
x° = 50°
x = 50

Two trains leave stations 360 miles apart at the same time and travel toward each other. One train travels at 110 miles per hour while the other travels at 90 miles per hour. How long will it take for the two trains to meet?
Do not do any rounding.
train A speed = 95 mph
train B speed = 105 mph
they are travelling towards each other
so effective speed = 200 mph.
distance = 360 miles
t= d/r
t=360/200
time = 1.8 hours they will meet

There are 2.54 centimeters In 1 inch. There are 100 centimeters in 1 meter. To the nearest meter, how many meters are in 201 inches?
Answer:
rounded to the neareast meter its 5
Step-by-step explanation:
Answer:
5 meters
Step-by-step explanation:
if there are 2.54 cm in 1 inch then there are .0254 meters in 1 inch
set up a proportion where inches over meters equals inches over meters
then cross-multiply:
'n' = # inches
.0254/1 = n/201
n = 201(.0254)
n = 5.1054 meters

Someone pleaseeee answer
Answer:
A
Step-by-step explanation:
We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.
5x ≥ 0 implies that x ≥ 0x + 3 ≥ 0 implies that x ≥ -3Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.
At Dairy Freeze, 2 of the last 10 sundaes sold had nuts. Considering this data, how many of the next 20 sundaes sold would you expect to have nuts?
Answer: 4
Step-by-step explanation:
By finding the relative frequency, we will see that we can expect that 4 out of the next 20 sundaes will have nuts.
How many of the next 20 sundaes can we expect to have nuts?
First, we know that 2 out of the last 10 sundaes sold had nuts. So the relative frequency of sundaes with nuts is:
R = 2/10 = 0.2
(the quotient between the number of sundaes with nuts and the total number of sundaes)
Then, out of the next 20 sundaes, we can expect that the number of sundaes with nuts will be:
N = R*20 = 0.2*20 = 4

Which expression is equivalent to 5^3?
Answer:
C and D
Step-by-step explanation:
5^3 - 5^0 = 125 - 1 = 124, so it's not A
5^12 / 5^4 = 5^(12-4) = 5^8, so it's not B
5^7 * 5^-4 = 5^(7+(-4)) = 5^3, so it can be C
5^0 * 5^3 = 5^(0+3) = 5^3, so it can be D
5 + 5^2 = 5 + 25 = 30, so it can't be E
A lawn is in the shape of a regular pentagon. It is made from 5 pieces of turf that are congruent triangles. Each triangle has an area of 19 in.2. What is the area of the lawn?
Answer:
The answer is 95 in^2
Step-by-step explanation:
The lawn is made up of 5 congruent triangles.
Since we know the area of the triangles we can add or multiply them.
5 * 19 = 95 so the area is 95 in^2
Determine whether the triangles are similar. If they are, write a similarity statement. Explain your reasoning.
Answer:
The triangles are not similar.
Step-by-step explanation:
Look at ratios of corresponding sides. If the triangles are similar, all the ratios will be equal.
Compare a side from [tex]\triangle{RTS}[/tex] with a side from [tex]\triangle{MQP}[/tex].
16/20 = 4/5
12/15 = 4/5 (looks promising, so far!)
20/26 = 10/13 Not at all the same as 4/5, so the triangles are not similar.
Find the slope of the line.
Answer:
-4/5.
Step-by-step explanation:
The 2 marked points are (-3, 2) and (2, -2)
So the slope = (-2-2)/(2- -3)
= -4/5.
Answer:
slope = - [tex]\frac{4}{5}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 2) and (x₂, y₂ ) = (2, - 2) ← 2 points on the line
m = [tex]\frac{-2-2}{2+3}[/tex] = [tex]\frac{-4}{5}[/tex] = - [tex]\frac{4}{5}[/tex]

Find the value of x³+ y³ + z³ – 3xyz if x² + y² + z² = 83 and x + y + z = 15
identity used is
x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).
then use
(x+y+z)² = x²+y²+z²+2(xy+yz+xz)
225= 83 + 2(xy+yz+xz)
xy+yz+xz = (225-83)/2
xy+yz+xz= 142/2
xy+yz+xz= 71
ok
now use identity
x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).
now
x³ + y³+ z³– 3xyz = 15 (83 – xy – yz – zx).
= 15[83 - (71)]
= 15×12
=180

Tyler is trying to pick out an outfit for the first day of school. He can choose from 3 pairs of pants, 7 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes. How many different outfits does Tyler have to choose from?
Answer: he can choose from three combinations
Step-by-step explanation: since three is the lowest number it can be paired with three others combinations
The number of different outfits Tyler choose is equal to 840
How to determine the number of different outfits?From the question, we have the following parameters that can be used in our computation:
Given 3 pairs of pants, 7 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes.
Thus, the number of different outfits is the products of the count of each apparel.
This is represented as;
Different outfits = Pants * T-shirts * Sweaters or hoodies * Pairs of shoes
Substitute the known values in the above equation;
Different outfits = 3 x 7 x 8 x 5
Evaluate;
Different outfits = 840
Hence, there are 840 different outfits

The perimeter of the triangle is 45cm.
Calculate the length of the hypotenuse.
I try it
Answer:
28.36
Step-by-step explanation:
Perimeter = 45
Perimeter = 2x + 3 + x + 6x + 1
2x + 3 + x + 6x + 1 = 45
9x + 4 = 45
9x = 45 - 4
9x = 41
X = 41/9
X = 4.56 or 4.6 (base on how may decimal places)
Hypotenuse
=6x + 1
= 6(4.56) +1
=38.36
Or
Hypotenuse
=6x +1
= 6(4.6) +1
=28.6
