how to solve the equation.. 1/4x=7
Answer:
b
Step-by-step explanation:
b
Answer:
x=27
Step-by-step explanation:
simplify 1/4
(1/4*x)-7=0
7=7/1=7*4/4
x-(7*4)/4=x-28/4
x-28/4=0
x-28/4*4=0*4
x-28=0
add 28 to both sides of the equation
x=28

Mr. Heath is TRYING to grow his hair out! Currently, his hair is 0.25 inches long. Each month, it grows 0.5 inches. His goal is to have hair that is 2.5 inches long. Let x be the number of months that Mr. Heath grows hair. Which of the equations represents Mr. Heath's hair growth journey? *
Answer: 0.25 + 0.5x = 2.5
Step-by-step explanation:
0.25 = the how long his hair is right now
0.5 = how much it grows each month
X= how many months it takes to reach 2.5 inches of hair
2.5= how long he'd like his hair to be

Find the value of x and y from the figure, if A, B & C are points on the circle with centre O.
Answer:
x=55 y=125
Step-by-step explanation:
X= 110/2=55
if BC is 110, BAC=250
so Y=250/2=125

What is the value of the expression? 8.5 - (-4.8) - 7
Answer:
6.3
Step-by-step explanation:
8.5 - (-4.8)
Let's focus on - (-4.8)
if a negative number is subtracted, it reverses itself
In other words, if a negative number is being subtracted, it is the same as being added as a positive number
So we change the equation to
8.5 + 4.8 = 13.3
Now we subtract 7 from 13.3
Since positive 7 is being subtracted, the rule for -4.8 does not apply to it
13.3 - 7 = 6.3

Helppppp please. I am stumped..
Answer:
D
Step-by-step explanation:
w = width
length = w + 0.6
A = l · w
A = w (w + 0.6)
A = w² +.6w
Answer:
D
Step-by-step explanation:
w = width
l = length = w + 0.6
Area = ( l ) * ( w )
Area = ( w + 0.6 ) ( w )
Area = w^2 + 0.6w

In a certain board game, a 12-sided number cube showing numbers 1–12 is rolled. If 4 such number cubes are rolled, what is the probability that at least 1 number cube will show a number 8 or larger?
The probability that at least 1 number cube will show a number 8 or larger is 0.83.
What is a binomial distribution in probability?In an experiment with two possible outcomes, the likelihood of exactly x successes on n repeated trials is known as the binomial probability (commonly called a binomial experiment). The binomial probability is
[tex]n^C_xp^xq^{n - x}.[/tex]
Given, In a certain board game, a 12-sided number cube showing numbers 1 to 12 is rolled.
So, Numbers that are 8 or larger is 8, 9, 10, 11, 12.
Now, The probability(p) of getting a number 8 or larger P(X ≥ 8) = 5/12.
hence q = 1 - p = 7/12.
Therefore, If 4 such cubes rolled the probability that at least 1 number cube will show a number 8 or larger is,
P(X≥ 8) = [tex]^4C_1(\frac{5}{12})(\frac{7}{12})^4+^4C_2(\frac{5}{12})^2(\frac{7}{12})^2+^4C_3(\frac{5}{12}^3)(\frac{7}{12})^1+^4C_4(\frac{5}{12})^4(\frac{7}{12})^0[/tex].
P(X≥ 8) = 4(0.41×0.115) + 6(0.173×0.34) + 4(0.072×0.58) + 1(0.030×1).
P(X≥ 8) = 0.283 + 0.35 + 0.167 + 0.030.
P(X≥ 8) = 0.83 or 83% chance.

One bag contains 2 green marbles and 4 white marbles, and a second bag contains 3 green marbles and 1
white marble. If Trent randomly draws one marble from each bag, what is the probability that they are both
green?
Answer:
1/4
Step-by-step explanation:
the first bag has 2 green marbles out of 6 total marbles, so the probability of getting a green marble out of the first bag is 2/6, or 1/3.
the 2nd bag has 3 green marbles out of 4 total marbles, so the probability of getting a green marble is 3/4
then multiply those together
1/3 × 3/4 = 3/12, which is 1/4
So that's the probability
