Answer:
75
Step-by-step explanation:
When you have 100% of something, it's all of that one thing, right? So if you were to turn 100% into a decimal, it would be 1. This means you can divide any percentage by 100 to turn it into a decimal. So, 30%=.3. When you multiply something by 2, you get two of that thing, right? And just the same, when you multiply something by half, you get half of that thing. This means you can multiply 250 by .3 to get .3 of it, or, 30%.
250*.3=75
Make x the subject of the formula [tex]mx^2=p[/tex]
Answer:
x = ± [tex]\sqrt{\frac{p}{m} }[/tex]
Step-by-step explanation:
Given
mx² = p ( divide both sides by m )
x² = [tex]\frac{p}{m}[/tex] ( take the square root of both sides )
x = ± [tex]\sqrt{\frac{p}{m} }[/tex]

which one please help y’all
Answer:
Numerator :)
Step-by-step explanation:
help please !!
don’t understand
Step-by-step explanation:
For two lines to be parallel they must have the same slope that is,M1=M2
For two lines to be perpendicular the slope of one must be the negative reciprocal of the other
Let's first find the slope of all three lines.
For line 1
6x-6=10y
2/5x-2/5=y
slope=2/5
For like 2
slope=5/3
For line 3
y=5/3x+2/3
We can therefore say that:
line 1 and line2 are neither parallel nor perpendicular
line 1 and line 3:
neither parallel nor perpendicular
line 2and line 3:
parallel lines

what is rotational symmetry
Answer:
Rotational symmetry, also known as radial symmetry in biology, is the property a shape has when it looks the same after some rotation by a partial turn. An object's degree of rotational symmetry is the number of distinct orientations in which it looks exactly the same for each rotation.
Answer:
A shape symmetry if it appears the same after a rotation

Jordyn went to the fair and paid $5 for admission (entrance fee). Additionally, she paid $2 for every ride she went on. How much money did Jordyn spend at the fair if she paid for admission and to go on 6 rides? *
Answer:
Jordyn spent $17 at the fair.
Step-by-step explanation:
From the information given, you know that the amount spent at the fair would be equal to the entrance fee plus the result of multiplying the price for every ride for the number of rides, which could be express as:
Total amount=5+2x, where:
x is the number of rides
With this formula, you can find the amount that Jordyn spent at the fair if she paid for admission and to go on 6 rides by replacing x with 6:
Total amount=5+(2*6)
Total amount=5+12
Total amount=17
According to this, the answer is that Jordyn spent $17 at the fair.

PLZZ HELP 75 points
Answer:
Number of small candles = 12
Number of large candles = 16
Step-by-step explanation:
Total candles = 28
x + y = 28 ---------------(I)
Cost of 'x' small candles = 4 *x = 4x
Cost of 'y' large candles = 6 *y = 6y
Total amount = $144
4x + 6y = 144 -------------(II)
Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'
(I) * (-4) -4x - 4y = -112
(II) 4x + 6y = 144 {Now, add}
2y = 32
y = 32/2
y = 16
Plug in y = 16 in equation (I)
x + 16 = 28
x = 28 - 16
x = 12
Answer:
12

first you read the question and use race
4(2x - 5) = 5x - 8
step by step
Answer:
x = 4
Step-by-step explanation:
4(2x - 5) = 5x - 8
Distribute 4: 8x - 20 = 5x - 8
Add 20 to both sides: 8x = 5x + 12
Substract 5x from both sides: 3x = 12
Divide both sides by 3: x = 4
Prices of a day ticket entrance at the Disney land are as follows adult 55 children 45 family 170 work out the percentage discount offer with the family ticket
Answer:
15% discount
Step-by-step explanation:
Given:- Prices for a day ticket entrance at Disneyland Paris resort are
adult=55
child=45
family(2 adults ,2 children)=170
To find:- The family discount in percentage
Solution:- According to the question, Prices for a day ticket entrance at Disneyland Paris resort are
adult=55
child=45
So the price for two adults is 2×55=110
and the price for two child is 45×2= 90
but for the family(2 adults ,2 children),the price is 170
So, though the number of members are same but here a family is getting (110+90-170)=30 rupees less than the actual price (200)
so the discount is 100×30/200 =15%
So the family will get 15% discount.

(3,1) and (w,9); slope = -8/3
W= ?
Answer:
w=0
Step-by-step explanation:
We know a point (3,1) and the slope (-8/3), so we can use point-slope form, which is y-y1=m(x-x1)
For reference, y1 is the y in the point, m is the slope, and x1 is the x in the point
So we subsitute it
y-1=-8/3(x-3)
do distributive prop.
y-1=-8/3x+8
add 1 to both sides
y=-8/3x+9
This is the equation of the line.
Now to find w, which is the x value.
The point will pass through line, so we can susbtitute the point into the equation.
9=-8/3x+9
subtract 9 from both sides
0=-8/3x
multiply by -3/8 on both sides (the reciprocal of -8/3), we need to isolate x
0=x
x=w
therefore, w=0
