thanks to everyone helping :)
Answer:
[tex]90[/tex]
Step-by-step explanation:
Let the unknown number be x
[tex]x \times \frac{70}{100} = 63 \\ x = \frac{63 \times 100}{70} \\ x = 90[/tex]
Hope this helps

~Hi1315~
Answer:
90
Step-by-step explanation:
If 70% of a number is 63, we can call that number x and make the following equation:
0.7x = 63
Now we just need to solve for x:
x = 63/0.7
x = 90
So the original number is 90.
How do we know we’re right? If you do 70% of 90 (aka 0.7*90), you’ll get 63, so we know it’s correct.

what is the volume of the figure
Answer:
5,376in^3
Step-by-step explanation:
find the volume of the smaller box first
10×4×12 = 480in^3
find volume of bigger box
17×12×24 = 4,896in^3
add both volumes 4,896 +480 = 5,376in^3
Answer:
v = 5,376
Step-by-step explanation:
So the first thing we have to do is figure out the volume for the first part of the cube figure.
To do this we just multiply H x W x L =
In this case v = 4,896
Now we do the same thing with the other rectangular prism:
10 x 4 x 12 = 480
Now that we have the 2 volumes we add them together:
4,896 + 480 = 5,376
Hence the total volume = 5,376

Answer: See explanation
Step-by-step explanation:
7.) 2 (x - 1) = 45
2x - 2 = 45
Add 2 to both sides
2x = 47
x = 23.5
8.) 5x - 2 = 2 (4)
5x - 2 = 8
Add 2 to both sides
5x = 10
Divide both sides by 5
x = 2
9.) x = 2 (30)
x = 60
10.) 3x - 6 = 2 (x)
3x - 6 = 2x
Add 6 to both sides
3x = 2x + 6
Subtract 2x from both sides
3x - 2x = 6
x = 6
2x + 1
Substitute x for 6
2 (6) + 1
12 + 1 = 13
2y = 13
Divide both sides by 2
y = 6.5

What is the slope of a line perpendicular to the line whose equation is x-y=6x. Fully reduce your answer.
Answer
1/5
Step-by-step explanation:
The slope of a perpendicular line is the negative reciprocal. Since y=-5x(m=-5), the slope is -(-1/5) which is 1/5
The slope of a line perpendicular to the line x - y = 6x is 1/5.
Here,
The equation of line whose equation is,
⇒x - y = 6x
We have to find the slope of a line perpendicular to the line x - y = 6x.
What is Equation of line?
The general equation of a straight line is,
y = mx + c
Where, m is the slope of the line.
Now,
The equation of line whose equation is,
⇒x - y = 6x
⇒ y = -5 x
Hence, the slope is -5.
The slope of a perpendicular line is the negative reciprocal.
So, The slope of a line perpendicular to the line x - y = 6x is,
⇒ [tex]-(\frac{1}{-5} )[/tex]
⇒ [tex]\frac{1}{5}[/tex]
The slope of a line perpendicular to the line x - y = 6x is 1/5.

The three statements that are true of a blackbody radiator are; A. It emits a range of wavelengths of EMR. C. It emits frequencies of EMR that depend on its temperature. D. It does not reflect much of the EMR it receives.
What is a blackbody radiator ?A blackbody radiator is an object which absorbs all the electromagnetic radiation at varying frequencies and angles of incidence.
Blackbody radiators posses a cavity which does not allow heat to escape from the radiator.
The electromagnetic spectrum is the distribution of radiation due to the different frequencies at which it radiates and its different intensities, that radiation is formed by electromagnetic waves, that are transverse waves formed by an electric field and a magnetic field perpendicular to it.
Therefore, we can conclude that the three statements that are true of a blackbody radiator are as listed.;
A. It emits a range of wavelengths of EMR.
C. It emits frequencies of EMR that depend on its temperature.
D. It does not reflect much of the EMR it receives.
Hence, the three statements that are true of a blackbody radiator are option A, C and D.

Jack has written the name of each planet of the solar system on a separate piece of paper and has placed all these pieces of paper in a bag. The names he included are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. If he picks a piece of paper at random from the bag, what is the probability that the name of the planet written on it contains at least 6 letters?
Answer:
The probability that it would contain at least 6 letters is: 5/8
Step-by-step explanation:
From the question given above,
We know that there are 8 planet that was given.
Mercury 7 letters
Venus 5 letters
Earth 5 letters
Mars 4 letters
Jupiter 7 letters
Saturn 6 letters
Uranus 6 letters
Neptune. 7 letters
Therefore,
P(at least 6 letters) + P( Less than 6 letters) = 1
P (at least 6 letters) + P (3 planet) = 1
P (at least 6 letters) + ( 3/8) = 1
P(at least 6 letters) = 1 - (3/8)
= 5/8

Patrick invested money into a special savers bank account each year money in the account earns 4% interest after one year, the total amount of money in the account was £291.20 how much did Patrick invest?
Answer: £280
Step-by-step explanation:
After a year, the total amount that was in the account was £291.20 which according to the question is 4% more than the amount Patrick invested.
Assume the amount invested is x.
x + 0.04x = 291.20
1.04x = 291.20
x = 291.20/1.04
= £280

Given:
[tex]\theta_1[/tex] is located in IV Quadrant.
[tex]\sin (\theta_1)=-\dfrac{24}{25}[/tex]
To find:
The value of [tex]\cos \theta_1[/tex].
Solution:
We have,
[tex]\sin (\theta_1)=-\dfrac{24}{25}[/tex]
We know that,
[tex]\sin^2 \theta+\cos^2\theta=1[/tex]
So,
[tex]\sin^2 (\theta_1)+\cos^2(\theta_1)=1[/tex]
[tex]\left(-\dfrac{24}{25}\right)^2+\cos^2(\theta_1)=1[/tex]
[tex]\cos^2(\theta_1)=1-\dfrac{576}{625}[/tex]
[tex]\cos^2(\theta_1)=\dfrac{625-576}{625}[/tex]
Taking square root on both sides, we get
[tex]\cos (\theta_1)=\pm \sqrt{\dfrac{49}{625}}[/tex]
[tex]\cos (\theta_1)=\pm \dfrac{7}{25}[/tex]
[tex]\theta_1[/tex] is located in IV Quadrant. In IV Quadrant the value of cos is positive. So,
[tex]\cos (\theta_1)=\dfrac{7}{25}[/tex]
Therefore, [tex]\cos (\theta_1)=\dfrac{7}{25}[/tex].
Graph by finding the intercepts
9x-15y = 45
Answer:
Look at picture
Step-by-step explanation:
X intercept is when y = 0. so...
9x -15*0 = 45
9x = 45
x = 5. so the coordinate is (5,0)
Y intercept is when x = 0. so...
9*0 - 15y = 45
y = -3. so the coordinate is (0,-3)
then you plot these 2 points and draw a line going across them
