Help pls I don’t remember how to do this so how do u find x, y, and z in this
Answer: 3) x = 87°; y = 93°; z = 63°
Step-by-step explanation:
x + 33 + 60 = 180 since they form a triangle.
x + 93 = 180
Subtract 93 from both sides
x = 87°
x and y are linear pairs so they're supplementary.
y + x = 180
y + 87 = 180
Subtract 87 from both sides
y = 93°
z + y + 24 = 180 since they also form a triangle
z + 93 + 24 = 180
z + 117 = 180
Subtract 117 from both sides
z = 63°
Hope this helped!

What is an equation of the line that passes through the point (−6,−1) and is perpendicular to the line 6x−y=7?
Answer:
y=-1/6x-2
Step-by-step explanation:
Lets find the slope of the given line
6x-7=y,m=6
The slope of the perpendicular line would be=-1/6
Using the point-slope form y-y1=m(x-x1)
y--1=-1/6(x--6)
y+1=-1/6(x+6)
6y+6=-x-6
6y=-x-6-6
6y=-x-12
y=-1/6x-2

We know he traveled 4.8 miles in 3 hours. However, since the question asks for his speed in miles per hour, we only want to know how far he travels in one hour. To find this, we just divide 4.8 by three, and find that he is traveling at 1.6 miles per hour.
Answer:
Speed = 1.6
Step-by-step explanation:
[tex]Speed=\frac{Distance}{Time} \\\\Speed = \frac{4.8}{3}=1.6[/tex]
Stacey has earned $9 interest over the past 20 months with an initial investment of $150. What is the simple interest rate she is earning? Express your answer to the nearest tenth of a percent. (It wants me to use the formula I=Prt which I don't remember)
Answer:
3.6%
Step-by-step explanation:
We are solving the above question, using the simple interest Formula:
I = PRT
Where
I = Interest = $9
P = Principal = $150
R = Interest rate = ??
T = Time in years = 20 months
We convert this to years
12 months = 1 year
20 months = x
x = 20/12
x = 1.67 years
Hence, making R the subject of the formula
R = I/PT
R = 9/150 × 1.67
R = 9/250.5
R = 0.0359281437
Converting to percentage
R = 0.0359281437 × 100
R = 3.59281437%
R = 3.6 %
The simple interest rate she is earning is 3.6%

Set A of six numbers has a standard deviation of 3 and set B of four numbers has a standard deviation of 5. Both sets of numbers have an equal mean. If the two sets of numbers are combined, find the variance.
Given:
[tex]\sigma_A=3[/tex]
[tex]n_A=6[/tex]
[tex]\sigma_B=5[/tex]
[tex]n_B=4[/tex]
[tex]\overline{x}_A=\overline{x}_B[/tex]
To find:
The variance. of combined set.
Solution:
Formula for variance is
[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x})^2}{n}[/tex] ...(i)
Using (i), we get
[tex]\sigma_A^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{n_A}[/tex]
[tex](3)^2=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]
[tex]9=\dfrac{\sum (x_i-\overline{x}_A)^2}{6}[/tex]
[tex]54=\sum (x_i-\overline{x}_A)^2[/tex]
Similarly,
[tex]\sigma_B^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{n_B}[/tex]
[tex](5)^2=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]
[tex]25=\dfrac{\sum (x_i-\overline{x}_B)^2}{4}[/tex]
[tex]100=\sum (x_i-\overline{x}_B)^2[/tex]
Now, after combining both sets, we get
[tex]\sigma^2=\dfrac{\sum (x_i-\overline{x}_A)^2+\sum (x_i-\overline{x}_B)^2}{n_A+n_B}[/tex]
[tex]\sigma^2=\dfrac{54+100}{6+4}[/tex]
[tex]\sigma^2=\dfrac{154}{10}[/tex]
[tex]\sigma^2=15.4[/tex]
Therefore, the variance of combined set is 15.4.

8x + 7 + 7x - 2=90
I need this to be solved ASAP
Answer:
ok so
Step-by-step explanation:
8x + 7 + 7x - 2=90=>
=> 15x+5= 90
=> 15x=90 - 5=>
=> 15x =85= x= 5.6666...
Hey there!
“8x + 7 + 7x – 2 = 90”
• FIRST: COMBINE your LIKE TERMS
(8x + 7x) + (7 – 2) = 90
‘8x + 7x = 15x’
‘7 – 2 = 5x’
“15x + 5 = 90”
• SECOND: SUBTRACT by 5 on BOTH SIDES
15x + 5 – 5 = 90 – 5
CANCEL out: 5 – 5 because that gives you 0
KEEP: 90 – 5 because it helps us solve for your x-value
‘90 – 5 = 85’
NEW EQUATION:
“15x = 85”
• THIRD: DIVIDE by 15 on BOTH SIDES
15x/15 = 85/15
CANCEL out: 15/15 because that equals 1
KEEP: 85/15 because it gives us our x-value
Reduce: 85/15 and it gives us: x
Answer: x = 17/3 ☑️
Good luck on your assignment and enjoy your day!

Subtract-3c2 + 12cd – 4d2 from 4c2 + 3cd + 2d?.
Your answer should be a polynomial in standard form.
Answer:
Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]
Step-by-step explanation:
We need to Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex]
(Note: Considering 2d^2 instead of 2d as thinking it typo error)
Subtracting from means we have to subtract [tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)[/tex]
Subtracting:
[tex]4c^2 + 3cd + 2d^2 -(-3c^2 + 12cd - 4d^2)\\=4c^2 + 3cd + 2d^2 +3c^2 - 12cd + 4d^2[/tex]
Combining like terms (Like terms are those that have same variables like 4c^2 and 3c^2 are like terms, 3cd and -12cd are like terms, 2d^2 and 4d^2 are like terms)
[tex]=4c^2+3c^2 + 3cd-12cd + 2d^2+4d^2 \\=7c^2-9cd+6d^2[/tex]
So, Subtract [tex]-3c^2 + 12cd - 4d^2[/tex] from [tex]4c^2 + 3cd + 2d^2[/tex] we get [tex]\mathbf{7c^2-9cd+6d^2}[/tex]

A train leaves at 0836 and arrives at 1057. It travelled at an average speed of 85 km/h. How far did it travel?
Answer:
199.75km
Step-by-step explanation:
Step one:
given data
We are told that the time of travel is from
8:36- to 10:57
which is 2 hours 21 minutes
Hence the time taken is 2.35 hours
the speed is 85km/h
Step two:
From the expression
speed= distance/time
85= distance/2.35
distance= 85*2.35
distance= 199.75km
Answer: it traveled a distance of 199.75Km
Step-by-step explanation:
From the question , Let 0836 be 8:36
and 1057 be 10:57
Time of departure= 8:36
Time of arrival = 10:57
Time traveled = 10:57- 08:36= 2 Hours 21 minutes
changing trhe time to hours becomes 21/60 = 0.35 hours + 2 HOURS = 2.35 hours
Step 2
Speed = Distance / Time
Distance = Speed x Time
=85 km/hr x 2.35 hours
=199.75Km

Does anyone know this?
Answer:
42 cm²
Step-by-step explanation:
Length of the shaded rectangle = 7 cm
Width of the shaded rectangle= 7 - (0.5 + 0.5) = 7 - 1
Width of the shaded rectangle = 6 cm
Area of the shaded rectangle = L × W
Area = 7 × 6 = 42 cm²
(5x² + 25x + 30)– (3x² + 6x + 3)
Notice that the second polynomial is subtracted from the first.
It's important to understand that the minus sign outside the
second set of parenthses can be thought of as a -1.
So we need to distribute the -1 through each of
the terms in the second set of parenthses.
So our problem will now look like 5x² + 25x + 30 - 3x² - 6x - 3.
Now, we combine like terms.
So we have 2x² + 19x + 27.

Answer:
A, y-intercept = (0,24)
Step-by-step explanation:
The y intercept is the one without a variable. You have to solve to find it in the other options.
Answer:
The first choice would be the best one.
Step-by-step explanation:
The y intercept occurs when x = 0 of the given polynomial.
All 3 answers will give you the correct answer. The y intercept is (0,24)
but the first one will be the quickest because all you need to do to find it is just eliminate any term with x in it.
2x^2 when x = 0 is 0
16x when x = 0 is 0.
That only leaves m(0) = 24 found just by looking at it.
The second one also works. 2 (0+4)^2 - 8 = 32 - 8 = 24
And the third one as well 2(6)(2) = 24

Answer:
-0.8 is the correct answer for this question
Step-by-step explanation:
mark me as brainliest
Answer:
t=-0.8
Step-by-step explanation:
You want to get the 't' by itself, so you will subtract 5 from both sides
5.25t=16.5t+9
Now, you want to subtract 16.5t from both sides
-11.25t=9
now you divide -11.25 from both sides.
t=-0.8
If y varies inversely as x. Using the coordinates (5, 3) and (x, 2.5), find the missing value x.
Answer:
(6, 2.5 )
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = [tex]\frac{k}{x}[/tex] ← k is the constant of variation
To find k substitute the coordinate point (5, 3 ) into the equation, that is
3 = [tex]\frac{k}{5}[/tex] ( multiply both sides by 5 )
15 = k
y = [tex]\frac{15}{x}[/tex] ← equation of variation
Using (x, 2.5 ) with y = 2.5 , then
2.5 = [tex]\frac{15}{x}[/tex] ( multiply both sides by x )
2.5x = 15 ( divide both sides by 2.5 )
x = 6
Thus point is (6, 2.5 )
