Answer:
When Amina is 18. Saad would be;
k. 14
Step-by-step explanation:
Let "x" represent Anita's current age and let "y" represent Saad's current age, we have;
Anita's age = 2 × Saad's age
Therefore;
x = 2 × y...(1)
In 4 years, we will get;
x + 4 = 1.5 × (y + 4)...(2)
Substituting the value of x in equation (1) into equation (2), we get;
2·y + 4 = 1.5·y + 1.5 × 4 = 1.5·y + 6
2·y + 4 = 1.5·y + 6
2·y - 1.5·y = 6 - 4 = 2
0.5·y = 2
y = 2/0.5 = 4
Saad's current age = y = 4 years
From equation (1), we have;
x = 2 × y = 2 × 4 = 8
Amina's current age = x = 8 years
When Amina is 18, we have;
18 = 10 + 8 = 10 + x
Therefore, Amina would be 18 in 10 years time from now, from which we have;
Saad would be 10 years + y = 10 years + 4 years = 14 years in 10 years from now
Therefore, when Amina would be 18 years in 10 years from now Saad would be 14 years.
The age of Saad is required when Amina will be 18.
Saad will be K. 14 years old.
Age problemsLet [tex]a[/tex] be the age of Amina
[tex]s[/tex] be the age of Saad
The age of Amina is twice as old as Saad
[tex]a=2s[/tex]
After 4 years Amina will be 50% older than Saad
[tex]a+4=(1+0.5)(s+4)\\\Rightarrow 2s+4=1.5(s+4)\\\Rightarrow 2s+4=1.5s+6\\\Rightarrow s=\dfrac{6-4}{2-1.5}\\\Rightarrow s=4[/tex]
So, Saad is 4 years old currently and Amina is [tex]2\times 4=8[/tex] years old.
They have a gap of 4 years between them.
When Amina will be 18 since Saad is younger his age will be [tex]18-4=14[/tex] years.

A.) A comparison of the area and circumference is not possible since the area cannot be determined.
B.) The numerical value of the circumference and area are equal.
C.) The numerical value of the circumference is greater than the numerical value of the area.
D.) The numerical value of the circumference is less than the numerical value of the area.
Test is on edge 2020
Answer:
C
Step-by-step explanation:
circumference is pi times diameter
pi times 3 is 9.42
area is pi times radius squared
radius is 1.5
1.5^2 is 2.25
pi times 2.25 is 7.06
5. Each dimensional analysis problem has taken you 1.5 minutes to complete. How many dimensional analysis problems could you complete in 6 weeks of Chemistry class?
Step-by-step explanation:
So we're trying to get from minutes to weeks. The time intervals in question are:
Minutes -> Hours -> Days -> Weeks
So we set up our dimensional analysis. We're solving for amount of problems, so that goes in the numerator of the first fraction:
[tex]\frac{1problem}{1.5min}[/tex]
Now we want to know how many minutes in an hour, so we multiply by the next fraction:
[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr}[/tex]
After that, we want to know how many hours in a day:
[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr} * \frac{24hr}{1d}[/tex]
and how many days in one week:
[tex]\frac{1problem}{1.5min} * \frac{60min}{1hr} * \frac{24hr}{1d} * \frac{7d}{1w}[/tex]
To solve the dimensional analysis problem, we multiply across the top of the entire expression, then divide across the bottom. So:
1 * 60 * 24 * 7 = 10,080
And then divide that by the bottom:
10,080 / 1.5 / 1 / 1 / 1 = 6,720
So you can solve 6,720 problems in one week. Multiply that by six and we get your answer:
40,320 dimensional analysis problems can be completed in 6 weeks of Chemistry class.
What is the answer for X?
Answer: I think it’s 14
Step-by-step explanation:
Answer:
x=8
Step-by-step explanation:
Alright so those to angles are complemntary meaning that when they are added together it will equal 90. So first you wanna set up an equation which would be 90 = 40+6x+2. Then you combine like terms and end up with 90=42+6x. Next you wanna subtract each side by 42 and now you have 48=6x. finally you divide each side by 6 and get x = 8
Write the slope-intercept form of the equation of each line given the slope and y-intercept.
Slope=-1/4, y-intercept =2
Answer:
y = -1/4x+2
Step-by-step explanation:
The SIF (slope intercept form) is pretty easy once you get it down. the slope is the interger before x, and the y-intercept is b. so, if you input each number into it's spot, it would become y = -1/4x + 2.

An oatmeal container has a diameter of 9 inches and a volume of 239.4 in3. What is the lateral surface area of the oatmeal container? Hint: You have to use the Volume to find the height before you can calculate the lateral surface area. Round your answer to the nearest tenth.
Answer:
Lateral surface area = 106.4 [tex]in^{2}[/tex].
Step-by-step explanation:
Assumed that the oatmeal container has the shape of a cylinder. Its lateral surface area can be determined by:
lateral surface area = 2[tex]\pi[/tex]rh
But,
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
where: r is the radius, and h is the height.
From the question, volume = 239.4 [tex]in^{3}[/tex], and diameter = 9 inches, then;
radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{9}{2}[/tex]
= 4.5
radius = 4.5 inches
Thus,
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
239.4 = [tex]\pi[/tex]x [tex](4.5)^{2}[/tex] x h
= 20.25[tex]\pi[/tex]h
h = [tex]\frac{239.4}{20.25\pi }[/tex]
= [tex]\frac{11.8222}{\pi }[/tex]
h = [tex]\frac{11.8222}{\pi }[/tex] inches
Therefore,
lateral surface area = 2[tex]\pi[/tex]rh
= 2[tex]\pi[/tex](4.5)([tex]\frac{11.8222}{\pi }[/tex])
= 2 x 4.5 x 11.8222
= 106.3998
Lateral surface area of the oatmeal container is 106.4 [tex]in^{2}[/tex].
A balloon is floating above a lake and a sunken canoe is below the surface of the lake. The balloon's vertical position is 12 meters and the canoe's is -4.8 meters. The equation: 12+d=-4.812 + d = − 4.8 represents this situation. What does the variable d represent? (distance or difference) What value of d makes the equation true?
Answer:
d represents distance
d = -16.8
Step-by-step explanation:
From the question, we are to find the vale of d from the expression
12+d = -4.8
Subtract 12 from both sides
12+d-12 = -4.8-12
d = -4.8-12
d = -16.8
Hence the value of d that makes two equation true is 16.8
d represents distance
d represents distance
d = -16.8
Calculation:12+d = -4.8
Here we have to do Subtract 12 from both sides12+d-12 = -4.8-12
d = -4.8-12
d = -16.8

Factor( special patterns): 36x^2-84x+49
Answer:
(6x - 7) (6x - 7)
Step-by-step explanation:
A perfect square trinomial will be in the form of [tex]a^2[/tex] ± [tex]2ab + b^2.[/tex] A trick to factoring a perfect square trinomial would to write it as [tex](a^2[/tex]±[tex]b^2)[/tex]. (When doing this, the sign in the middle is determined by the middle sign in the original trinomial).
[tex]36x^2 -84x + 49[/tex] is known as a perfect square trinomial, too. Its first and last terms are both perfect squares (6x squared makes [tex]36x^2[/tex], 7 squared makes 49) and the middle term is 2 times the square roots of both of the other terms ( [tex](2) (7) (6x)[/tex] is [tex]84x[/tex]).
So, we can use the trick described earlier, and the answer would be [tex](6x-7)^2[/tex], also known as (6x-7) (6x-7).
