Find the number that makes the ratio equivalent to 7:8.
:24
Answer:
21:24
Step-by-step explanation:
7:8 is your ratio
so if _:24 is equivalent, you have to figure out what 24 is divisible by to equal 8
8×3=24
so now we have to multiply 7 by 3
7×3=21
so your answer is 21:24 = 7:8
hope this helps :)

Answer:
Equation is P=4s
Step-by-step explanation:
There is a pattern here:
8 is 4 times as much as 2
12 is 4 times as much as 3
20 is 4 times as much as 5
40 is 4 times as much as 10
Since P varies directly with s, we can make an equation: P=4s where k=4 in the form of y=kx
What fraction is equivalent to 0.1666666...
Answer:
1/6
Step-by-step explanation:
The value of the fraction that is equal to the number 0.16666... would be 5/30.
Given that,
Change the number 0.16666... into a fraction.
Used the concept of fraction which stated that,
A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction.
Let us assume that the number 0.1666.. equal to x.
Hence,
x = 0.166666 ..... .. (i)
Multiply by 10 on both sides,
10x = 1.66666... (ii)
Also, multiply by 100 in equation (i),
100x = 16.6666.. (iii)
Subtract equation (ii) from (ii),
100x - 10x = 15
90x = 15
x = 15/90
Simplify for the simplest form,
x = 5/30
Therefore, the value of the fraction is 5/30.

Answer:
x=8
Step-by-step explanation:
Simplifying
Combine like terms
Solving
two thirds a number x plus 6 is 8
2/3x+6 = 8
subtract 6 from both sides
2/3x = 2
divide both sides by 2/3
x = 3
Answer:
x = 3
Step-by-step explanation:
Multiply both sides of the equation by 3
2x + 18 = 24
Move Constant to the right-hand side and change its sign
2x = 24 - 18
Subtract the numbers

What is a Quadratic equation?ax²+bx+c=0, with a not, equals 0 is a quadratic equation, which is a second-order polynomial equation in a single variable. It has at least one solution because it is a second-order polynomial equation, which is guaranteed by the algebraic fundamental theorem. The answer could be simple or complicated.
given a Graph of a quadratic equation.
Contrarily, parabolas are used to graph quadratic equations. In other words, the data will be displayed as either an "open" or "upside-down" U-shaped curve. The graph is always quadratic if you are drawing a graph from a function and the equation involves x².
in this graph, we can observe that graph has only one root at x = -3
therefore the equation of the Given parabola is
(x + 3)² = 0
or
(x +3)(x + 3) = 0
therefore, the equation choice could represent the graph given will be (x +3)(x + 3) = 0.

Given the probability that "she's up all night 'til the sun" OR "she's up all night for good fun" is 0.36, the probability that "she's up all night for good fun" is 0.41, and the probability that "she's up all night 'til the sun" is 0.36, what's the probability that "she's up all night 'til the sun" AND "she's up all night for good fun"?
Answer:
0.41
Step-by-step explanation:
S = "she's up all night 'til the sun"
F = "she's up all night for good fun"
P(S or F) = P(S) + P(F) − P(S and F)
0.36 = 0.36 + 0.41 − P(S and F)
P(S and F) = 0.41

Emma is 10 years younger than Joseph. Joseph's age 6 years from
now will exceed twice Emma's age 2 years ago by 3 years.
How old is Em ma and Joseph now?
Answer:
Step-by-step explanation:
let Emma age be x now
Let Joseph age be y now
If Emma is 10 years younger than Joseph, then x = y-10
six years from now:
Emma will be x+6 years
Joseph will be y+6 years
If Joseph's age 6 years from now will exceed twice Emma's age 2 years ago by 3 years, then:
y+6 = 2(x+6-2) + 3
y+6 = 2(x+4)+3
y + 6 = 2x+11
y + 6 = 2(y-10)+!1
y + 6 = 2y-20+11
y - 2y = -9-6
-y = -15
y = 15
Since x = y -10
x = 15-10
x = 5
Hence Emma is 5years old now and Joseph is 15years old now

This gives us ( x+2) ( 2x^3 -9x^2 +13x -6)
We see that there is a zero at 2
Using synthetic division ( 2x^3 -9x^2 +13x -6)

2 -5 3 0
This gives us ( x+2) ( x-2) ( 2x^2 -5x+3)
We can factor ( 2x^2 -5x+3)
