Rose wants to get 90% on a 40 question quiz. How many questions must she get correct?
Answer:
36
Step-by-step explanation:
We can use the is/of=%/100 proportion...
x = 90
40 100
First, we need to multiply 90 by 40. 90x40=3,600.
Next, we have to divide 3,600 by 100. 3,600/100=36.
Rose needs to get 36 questions correct to get at least a 90%.
Hope this helps!! Have a great day C:

3. Adrian is 8 years older than his brother, Jose. In 3 years he will be twice as old as his brother. Find the present age of each.
Answer:
Age of Jose = 5 years
Age of Adrian = 13 years
Step-by-step explanation:
Let:
Age of Jose = x
Age of Adrian = x+8
After 3 years
Age of Jose = x+3
Age of Adrian = x+8+3 = x+11
Now, we are given, in 3 years he will be twice as old as his brother.
So, we can write
Age of Adrian = 2 (Age of Jose)
x+11 = 2(x+3)
x+11=2x+6
2x-x=11-6
x=5
So, we get value of x = 5
Now, the present ages will be:
Age of Jose = x = 5 years
Age of Adrian = x+8 = 5+8 = 13 years
Adrian is 8 years older than his brother, Jose. In 3 years, he will be twice as old as his brother. Find the present age of each.
Answer:Jose is currently 5 years old.Adrian is currently 13 years old.Solution and Explanation:Let's represent the age of Jose as [tex]\large\rm x[/tex]
According to the problem, Adrian is 8 years older than Jose, so Adrian's age can be represented as [tex]\large\rm x + 8[/tex].
In 3 years, Adrian's age will be [tex]\large\rm (x + 8) + 3[/tex] and Jose's age will be [tex]\large\rm (x + 3)[/tex].
The problem also tells us that in 3 years, Adrian will be twice as old as Jose:
[tex]\Large\begin{aligned}\rm{(x + 8) + 3}& =\rm{2(x + 3)}\\\rm{x + 11}&=\rm{2x +6}\\\rm{\cancel{x\red{-x}} + 11}&=\rm{2x \red{-x} + 6}\\\rm{11}&=\rm{x + 6}\\\rm{11\red{-6}}&=\rm{x + \cancel{6\red{-6}}}\\\bold{5}&=\rm{x}\end{aligned}[/tex]
So Jose is currently 5 years old.
To find Adrian's age, we can use the fact that Adrian is 8 years older than Jose:
[tex]\Large\begin{aligned}\rm{Adrian's\: age}& =\rm{x + 8}\\\rm{Adrian's\: age}&=\rm{\red{5} + 8}\\\rm{Adrian's\: age}&=\bold{13}\end{aligned}[/tex]
Therefore:
Jose is currently 5 years old.Adrian is currently 13 years old.[tex]\\\\[/tex]

All you want to do is set the radical equal to zero to determine your domain, and sinse substituting [tex]\displaystyle \frac{1}{2}[/tex] in for [tex]\displaystyle x[/tex] would make this 0, it would be the INCLUDED endpoint, so your bracket faces [tex]\displaystyle \frac{1}{2},[/tex] then continues on infinitely.

How many cubes with side lengths of cm does it take to fill the prism?
4
1
1
cm
4
3
cm
2 cm
4
Answer:
135 small cubes fill the prism
Step-by-step explanation:
Find the volume of the prism.
V = l * w * h
l = 2 1/4 = 2.25
w = 3/4 = 0.75
h = 1 1/4 = 1.25
V = 2.25 * 0.75 * 1.25
V = 2.109375
I wouldn't round this quite yet.
V of 1 small cube = 1/4 * 1/4 * 1/4 = .015625
So divide the volume of the prism by the volume of the small cube
2.109375/0.015625 = 135

Answer:
210°
Step-by-step explanation:
To change from radians to degrees, multiply 7π/6 by 180/π

Write down the ratio of 450 grams to 15 grams
The ratio of 450 grams to 15 grams is 30:1.
What is Ratio?A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.
Given:
ratio of 450 grams to 15 grams
So, the ratio is
= 450/ 15
= 30 / 1
Hence, the ratio of 450 grams to 15 grams is 30:1.
