Myles is working on his typing. He types for 3 minutes straight and is able to type 150 words. Determine how long it would take for Myles to type 900 words.
Select all values that would make the following inequality true: x ≥ -10
-10
-14
-2
0
Answer: -10; -2; 0
Step-by-step explanation:
≥ means greater or equal than.
-10 is equal -10, true.
-14 is less than -10, so false.
-2 is greater than -10, true
0 is greater than -10, true
so the answer is -10, -2 and 0 can make this inequality true.

Help Me, Now! C. At what value of x will each function equal 90? Both functions will equal 90 when x =
Answer:
When x=2
Step-by-step explanation:
Well in the first one it tells you that 2x is 90.
In the second it's y=40x+10
So you plug 2 in as the x.
y=40(2)+10
y=80+10
y=90
Hope this helps

Answer:
x= 7, y=0 (7,0)
Step-by-step explanation:
If a triangle measures 180 degrees, and you know that one of your angles = 90, and another angle = 45, what is the measure of the third angle?
Answer:45
Step-by-step explanation:
Well just take the sim of the two given angles then subtract them from the total measure of the triangle which is 180
State true or false. If 9 is the solution of variable x in the equation fraction numerator 5 straight x space minus space 7 space over denominator 2 end fraction space equals space straight y, then the value of y is 28
Answer:
False
Step-by-step explanation:
Based on what is stated in the question :
Expressing the worded equation Mathematically,
(5x - 7) / 2 = y
If y = 28
(5x - 7) / 2 = 28
Cross multiply
5x - 7 = 28 * 2
5x - 7 = 56
5x = 56 + 7
5x = 63
x = 63 / 5
x = 12.6
Hence, x ≠ 9

Answer:
1) 4 hours 2) 144 miles 3) 12 miles
Step-by-step explanation:
60/5=12
72/6=12
120/10=12
180/15= 12
1) 48 miles / 12 miles = 4 hours
2) 12 hours x 12 miles = 144 miles
3) 1 hour x 12 miles = 12 miles

Step-by-step explanation:
Median data dihitung sebagai
= 1/2 (n + 1) suku ke-1
Dimana n = Jumlah suku
= 10
Langkah 1
Kami mengatur ulang
8, 9, 10, 10, 12, 12, 13, 15, 15, 17
Langkah 2
Suku 1/2 (n + 1)
1/2 (10 + 1) istilah
= 11/2 istilah
= 5,5 suku
Istilah ini antara istilah ke-5 dan ke-6
Suku ke-5 = 12
Suku ke-6 = 12
= 12 + 12/2 = 24/2
= 12
Median data adalah 12
7 times the quantity y divided by 4
What is the standard form of the following equation?
y= 2(x - 1)^2 + 4
A) y = 2x2 + 4
B) y = 2x² - 4x + 8
C) y = 2x2 – 2x + 4
D) y= 2x2 - 4x + 6
y = 2(x - 1)² + 4
y = 2(x² - 2x + 1) + 4
y = 2x² - 4x + 2 + 4
y = 2x² - 4x + 6

If a coordinate was dilated from (-3, 2) to (-6, 4), what was the scale factor used?
Given:
A coordinate pair was dilated from (-3, 2) to (-6, 4).
To find:
The scale factor.
Solution:
We need to divide the coordinate of dilated point by the corresponding coordinate of original point to find the scale factor.
The value of scale factor is:
[tex]k=\dfrac{x\text{-coordinate of image}}{x\text{-coordinate of original point}}[/tex]
[tex]k=\dfrac{-6}{-3}[/tex]
[tex]k=2[/tex]
Therefore, the scale factor is 2.
f(x)1/x please help me
Answer:
You are going to take the shape and flip if across the x Axis, reversing it essentially. then you will move it up 4, so of it is a square with one corner at (2,3) it will go to (5, 7) and all the other point will move together if I remember right. I last did this 3 years ago, I hope I help, next time show the whole graph with the number and I would have put a visual to show you the answer. Good luck
Find the area of the composite shape below.

4,368 please I hope it is correct I used a calculator
If the mean of 6 10 12 x 16 18 is 15 find the value of x
Answer:
x=28
Step-by-step explanation:
I am assuming the mean is arithmetic mean. So we first add up the numbers:
6+10+12+18+16+x
=22+10+30+x
=22+40+x
=62+x
Then since there's 6 numbers in total, we have an equation:
[tex]\frac{62+x}{6}=15\\62+x=90\\x=28[/tex]
The answer is 28!

A cylinder whose radius is 21cm has a curved surface area of 528cm2. Calculate the height of the cylinder.
Answer:
110888
Step-by-step explanation:
v=surface area *radius
v=528*21=110888cm3
Answer: the height is 4
I think you make mistakes
but that is the height
Step-by-step explanation:
h =height=?cm
R=radius=21cm
A =surface area 528cm

Answer:
Step-by-step explanation:
a=1
r=-6/1=-6
[tex]S_{7}=a\frac{1-r^n}{1-r} =1\frac{1-(-6)^7}{1-(-6)} \\=\frac{1+6^7}{1+6} \\=\frac{1+279936}{7} \\=\frac{279937}{7} \\=39991[/tex]
which relation represents a function?
Answer:
the last one is the answer I thin
Answer:
D
Step-by-step explanation:
Hey There!
Remember in order for the relation to be a function none of the x values can repeat
For the first one the x value 0 repeats therefore it is not a function
for the second one the x value -7 repeats thus meaning that its not a function
for the third one the x value 6 repeats hence, it is not a function
for the last one each input has a different output therefore it is a function

Ken had 80 rubber bands, he sold 10 and 10
got damaged. How many good rubber bands
were left with Ken? What percentage of
rubber bands were left?
Answer:
60 were left with Ken, and that is 75%
Step-by-step explanation:
80-10 = 70
70-10 = 60
60/80 = x/100, simplify & cross multiply
6/8 = x/100
600 = 8x
x = 75

if the simple interest on 2000 for 4 years is 4000 then what is the interest rate
Answer:
Principal = Rs 2000
Time = 4 years
Interest = Rs 400
Now, Interest= Principal×Rate×Time/100
400= 2000×R×4/100
R= 400×100/2000×4
