0.34 is 10 times as great as what number?
Answer:
0.034
Step-by-step explanation:
the opposite of multiplication is division. 0.34 divided by 10 is 0.034. you can also figure this out by moving the decimal to the left once.
0.34 is 10 times greater than 0.034.
What is a decimal ?A decimal is represented by a dot or a point it separates the whole part and the fractional part of the given number.
According to the given data
0.34 is 10 times as great means we have to divide 0.34 by 10
which is
= (0.34/10)
= 0.034
∴ 0.34 is 10 times greater than 0.034.
We can also do this by simply moving the decimal to one left of the digit.
For example if given a.cb and we have been asked what number is 100 times greater than a.bc we can simply move the decimal to the right by 2 place then it will be abc.

A figure is rotated 180°clockwise, then 90°counterclockwise. Which single rotation is equivalent to this?
Answer:
90
Step-by-step explanation:
180-90
clockwise-counterclockwise
A single rotation of 90° in the clockwise direction is equivalent to the rotation given.
For the image of a figure to overlap with itself, the amount by which the figure should be rotated is?For the image of a figure to overlap with itself, the figure should be rotated by 360°
We have a image that is is rotated 180°clockwise, then 90° counterclockwise.
The rotation of the image which is is rotated 180°clockwise first and then 90° counterclockwise can be replaced by a single rotation of 90° in the clockwise direction. Mathematically -
Ф = + 180° + (-90°) = + 90°
Therefore, a single rotation of 90° in the clockwise direction is equivalent to the rotation given.

In applications, most initial value problems will have a unique solution. In fact, the existence of unique solutions is so important that there is a theorem about the existence and uniqueness of a solution. Consider the initial value problem dy/dx=f(x,y), y(x) = yo. If f and f/y are continuous functions in some rectangle R= {(x,y):a Use the method of separation of variables to find the solution to dy/dx =y1/3? Begin by separating the variables. dy= dx
Answer:
The answer is "[tex]\bold{ y^{ \frac{2}{3}}} = \frac{2}{3}x + c} \\\\[/tex]"
Step-by-step explanation:
By using the given method we separate the above-given variable and find the solution of:
[tex]\bold{\frac{dy}{dx} =y^{\frac{1}{3}}}[/tex]
Solution:
[tex]\to \frac{dy}{dx} =y^{\frac{1}{3}}\\\\\to \frac{dy}{y^{\frac{1}{3}}} =dx\\\\\to y^{ - \frac{1}{3}} dy =dx\\\\[/tex]
Integrate the above value:
[tex]\to \int y^{ - \frac{1}{3}} dy = \int 1 dx\\\\\\\to \frac{y^{ - \frac{1}{3} +1}}{- \frac{1}{3} +1} = x \\\\ \\\to \frac{y^{ \frac{-1 +3}{3}}}{ \frac{-1+3}{3} +1} = x \\\\\\\to \frac{y^{ \frac{2}{3}}}{ \frac{2}{3} +1} = x \\\\\\\to \bold{y^{ \frac{2}{3}}} = \frac{2}{3}x + c} \\\\[/tex]

Find the circumference of a circle with radius, r = 12m.
Give your answer in terms of π.
Answer:
C = 24 pi meters
Step-by-step explanation:
The circumference of a circle is given by
C = 2 * pi *r
C = 2 * pi * 12
C = 24 pi meters
Answer:
24π
Step-by-step explanation:
The circumference of a circle uses this equation: [tex]2\pi r[/tex]. Just like the last question I answered, you want to give the answer in terms of pi, so we aren't going to multiply pi.
The question gives us the radius so we don't have to divide anything, we plug in r with 12 as is.
[tex]C=2\pi 12[/tex]
Now multiply the 2 and the 12 so it will be in terms of pi.
[tex]C=24\pi[/tex]
In terms of pi, the circumference is 24π.

The roots of a quadratic equation are 5 and 2/3. If one of the two factors is x-5, what could be a second
factor?
Explain your reasoning.
Answer:
Step-by-step explanation:
Given the roots of quadratic equation to be 5 and 2/3, the two factors are x-5 and x-2/3.
The variable in question are both subtracted from the root given to get the actor of the quadratic equation or polynomial. We can get the resulting quadratic function by multiplying both factors together as shown;
(x-5)(x-2/3)
= x²- 2x/3 -5x +10/3
= x²-(2x-15x)/3+10/3
= x²-17x/3 +10/3
Multiply through by 3
= 3x²-17x +10 = 0
The resulting quadratic equation for both factors will be 3x²-17x +10 = 0 and the other factor is x-2/3
1. Layne rode his bike from Point A to B by
using Cherry Street. How much further would
his trip have been if he took Orange Drive
and Peach Avenue instead?
PLEASE HELP ASAP ILL GIVE BRAINLIEST DUE TODAY!!
Answer:
cherry street is 85 yards, while orange dr. and peach ave. is 113 yards, meaning that cherry st. is 28 yards faster
Step-by-step explanation:
(85 x 85) - (77 - 77) = 1296
square root of 1296 is 36
77 + 36 = 113
113 - 85 = 28
this means that cherry st. is 28 yds faster
using the Pythagorean Theorum
The distance that Layne would have to travel further if he took the given paths is required.
If Layne took Orange Drive and Peach Avenue instead his trip would be 28 yards longer.
Pythagoras theoremc = Length of Cherry st. = 85 yards
a = Length of Orange dr.
b = Length of Peach av. = 77 yards
The angle between orange drive and peach avenue has been assumed to be [tex]90^{\circ}[/tex].
We need to find the sum of the distances of the paths orange drive and peach avenue.
So, we need to find the length of orange drive.
Applying the Pythagoras theorem
[tex]a^2+b^2=c^2\\\Rightarrow a=\sqrt{c^2-b^2}\\\Rightarrow a=\sqrt{85^2-77^2}\\\Rightarrow a=36\ \text{yards}[/tex]
The distance traveled when orange drive and peach avenue is taken is
[tex]36+77=113\ \text{yards}[/tex]
The extra distance traveled
[tex]113-85=28\ \text{yards}[/tex]

PLEASE HELPPPPP ME I HAVE SO MUCH TO DO ONLY 2 questions
Answer:
1)37.68
2) 113.04
Step-by-step explanation:
So for number 1, circumfence is diameter times pi, so diameter is 12 and assuming 3.14 for pi then 12(3.14)=37.68
Number 2, the area of a circle is pi(radius)^2 so we know the diameter is 12 and to find raidus we divide 2 since raidus is half of the diameter, square the radius which is 6^2 which will give you 36, assuming pi is 3.14 multiply 36 by 3.24, 36(3.14)=113.04
The drama department at Oak Hill High School is hosting a spring play. Tickets for the play are $4 for students (s) and $6 for adults (a). The drama department wishes to raise at least $1600 from this play and have at least 300 people attend the play.

Which of the following systems of inequalities models this situation?
4s + a ≥ 1600
s + 6a ≥ 300
4, s, + , a, ≥ 1600, , s, + 6, a, ≥ 300
4s ≥ 1600
6a ≥ 300

s + a ≥ 300
4, s, + 6, a, ≥ 1600, , s, + , a, ≥ 300
6a ≥ 1600
4s ≥ 300
Answer:
pretty sure its c
Step-by-step explanation:
4s+6a represents how much money the tickets cost per person and they want to raise at least 1600 dollars
s+c represents how many people and they want at least 300 people to attend.

How do I subtract decimals from whole numbers?
Answer:
Just use long subtraction by expanding the decimal places of the whole number. This is done by adding a point, and enough zeros to it to match the number of decimal digits in the other number (digits after the decimal point).
12345678
i.e: 5 - 2.48374827, 2.48374827 has 8 decimal digits, so add 8 zeros after the point.

This is basically borrowing a group of 10s which are the same as 1s in the next decimal place up.
