Answer:
x = 4
Step-by-step explanation:
If y = 36, that means the original y = 18 was multiplied by 2. So, we have to multiply x = 2 by 2 as well.
2 * 2 = 4, so x = 4
A student orders food from the menu shown below he orders 1 hotdog 1 popcorn 3 bags of chips and one soda how much money did he spend
(1 hotdog : 1.75)
( 1 popcorn : 1.25)
(3 bags of chips : 0.75)
(One soda : 1.50)
Answer:
1.75 + 1.25 + 1.50 + .75(3) = $6.75 total
Step-by-step explanation:
Make sure to multiply .75 x 3 because there are 3 bags of chips. That gives you $2.25 in chips to add to the hotdog, popcorn, and soda total.
Find the slope of the line through the pair of points: (3,4)and (0,2)
Step-by-step explanation:
To find the slope, we'll use this formula:
[tex] \frac{y2}{x2} - \frac{y1}{x1} = m[/tex]
m will represent our slope.
Use the first point as the second in the formula, as we'll subtract for the correct slope.
Substitute the 2 given points into the formula format:
[tex] \frac{4}{3} - \frac{2}{0} = m[/tex]
Subtract:
[tex] \frac{2}{3} = m[/tex]
The slope is 2/3.
Answer:
[tex]\boxed{\sf{\dfrac{2}{3} }}}[/tex]
Step-by-step explanation:
A slope formula is all you need to use to find the slope.
Slope:
[tex]\sf{\dfrac{Y_2-Y_1}{X_2-X_1} }[/tex]
y2=2
y1=4
x2=0
x1=3
Rewrite the problem.
[tex]\sf{\dfrac{2-4}{0-3} }[/tex]
Then, solve it.
[tex]\sf{\dfrac{2-4}{0-3}=\dfrac{-2}{-3}=\boxed{\sf{\dfrac{2}{3} }}} }[/tex]
As a result, the slope is 2/3, which is our answer.

500 apples are taken at random from a large basket and 50 are found to be bad. Estimate the proportion of bad apples and assign limits within which the percentage most probabilities lies
Answer:
Step-by-step explanation:
probability = 50/500= 1/10
which means that there is probability of 1 Apple will be bad from 10 apples.
Ann started walking to her grandparents' house at 9:38 A.M. It took her 41 minutes to get there. Then, she played in the backyard for 1 hour and 56 minutes.
When did Ann finish playing in the backyard?
The time Ann finished playing in the backyard is 12 : 15 pm
How to find the time Ann finish playing in the backyardTime Ann started walking to her grandparents' house = 9:38 A.MTime taken to get there = 41 minutesTime taken to play in the backyard = 1 hour and 56 minutesTotal time = 9:38 + 41 minutes + 1 hour 56 minutes
= 10:19 + 1 hour 56 minutes
= 12 : 15 pm

what is 15% of 900? please help
also see comments
Answer:
135
Step-by-step explanation:
Multiply .15 by 900
0.15 x 900 = 135
Hope this helps :)
Answer:
135
Step-by-step explanation:
To find 15% of a number, we can find 10% first then 5%
10% of 900 is 90 (900 ÷ 10 = 90)5% of 900 is 45 (half of 10% of 90)Therefore, 15% of 900 is 135We can also turn 15% into a decimal by dividing 15 by 100: 15 ÷ 100 = 0.15 Now, we can treat 'of' as × and do 0.15 × 900 which is 135.

Consider the complex numbers and in the complex plane below:
Find the rectangular forms of v,w,z
and enter them in that order.
Answer:
v = √2 +√2iw = -2 -2√3i . . . ("i" is not under either radical)z = 0 -3iStep-by-step explanation:
A suitable calculator can perform polar to rectangular conversion for you. If you like to do it "by hand", the conversion is ...
(r; θ) ⇔ r·cos(θ)+ r·sin(θ)i
Your numbers translate to ...
v = √2 +√2iw = -2 -2√3iz = 0 -3i_____
Additional comment
We aren't often asked to read polar graphs. The concentric rings here are taken to be 1 unit apart. The radial lines are 15° apart. Then the various points are ...
v = 2∠45°
w = 4∠-120°
z = 3∠-90°
As you can see, the TI-84 work-alike in the attachment is able to write and understand numbers in this form. Other calculators treat complex numbers as vectors [magnitude, angle], or as coordinates with a special separator (semicolon) to indicate polar coordinates vs. complex plane coordinates: (r; θ) vs. x +iy
In any event, you need to be careful to understand the units the calculator uses for angles. In the attached, we have set the angle units to degrees. Most spreadsheets default to radians.

Two angles are supplementary. The measure of the larger angle is 28 more than 3 times the measure of the smaller angle.
Find the measures of both angles.
ATQ
[tex]\\ \rm\longmapsto 3x+28+x=180[/tex]
[tex]\\ \rm\longmapsto 4x+28=180[/tex]
[tex]\\ \rm\longmapsto 4x=152[/tex]
[tex]\\ \rm\longmapsto x\approx 38[/tex]
3x+28=180-38=142Let's assume that ,
x is the smaller angle
3x+28 is the larger angle
then,
ATQ,
x + 3x+28 = 180°
4x +28 = 180°
4x = 180°-28°
4x = 152°
x = 38°
putting the value of x in the larger angle
⇢3x +28 = 3 x 38° +28° = 142°
hence , the measure of the smaller angle is 38° & the larger one = 142°

b. It has an obtuse angle which measures less than 90°
c. It has an obtuse angle which measures greater than 90°.
d. It has an acute angle which measures greater than 90
Answer:
c
Step-by-step explanation:
an obtuse angle is an angle which is greater than 90° but less than 180° so an obtuse triangle will have an angle that measures greater than 90
Answer:
c. It has an obtuse angle which measures greater than 90°.
Step-by-step explanation:
An obtuse angle is any angle greater than 90°, and an obtuse triangle is a triangle in which one of the angles is an obtuse angle.
Three pounds of apples costs $1.09. How much will 11 pounds of apples cost? Round to the nearest cent.
Answer:
Step-by-step explanation:
Comment
This is a proportion question. That means that the ratios given are equal. There are 4 facts all together. 3 are given, you have to solve for the 4th. The procedure is the same every time.
Equation (proportion)
cost of apples 1.09/ Number of apples (3) = cost of nearly a dozen (x)/Number = 11.
1.09/3 = x / 11 Cross Multiply
3x = 1.09 * 11 Combine the right
3x = 11.99 Divide by 3
3x/3 = 11.99/3
x = 3.99

£245 increased by 25%?
Answer:
306.25
Step-by-step explanation:
What you need to do is multiply 245 by .25 (the decimal form of 25%). Then you should get 61.25, which is what the increase would be. Then, using the product, add 245 with 61.25 and you'll get the answer.
(Hope this helps)
Answer:
61.25 Euro
Step-by-step explanation:
Hopefully this is right. I'm American so I had to do a little converting with the currency. How you solve it is you multiply 245 by 25 and then divide by 100. Whenever percentage is involved think of the butterfly method.
[tex]x/250=25/100[/tex]
In this problem X is what you're trying to solve for; what the number will be AFTER the increase. The denominator will always be the original amount/price. Then on the other side you put the percentage over 100, since percentages go from 0% to 100%, kinda like quarters.

Solve 20% of blank = 40
Answer: 200
Step-by-step explanation:
Let the unknown number be x.
Therefore, 20%*x = 40
20% as a fraction is 1/5.
Therefore x*(1/5) = 40
Multiply both sides by 5:
x = 200
Which statement is true?
A. 30 is 3% of 100.

Answer:
A. 30 is 3% of 100
Step-by-step explanation:
So if 10 is 1% of 100, then 30 is 3% of 100

okay so basically we see two rectangles right, so we can subtract the small from the big to leave the shaded region behind: so we take the area of the big rectangle first, (x+5)*4 and then we subtract the small area which is 2*2 so that we get an equation like this: (x+5)*4 - 4 --> 4x+20-4 --> 4x+16
