Step-by-step explanation:
The formula for calculating the area of a square is expressed as;
A = x² where;
x is the length of one side of the square
Given
x = 10in
A = 10²
A = 10 * 10
A = 100in²
Area of the square with side length 10in is 100in²
From the equation A = x², we can see that as the value of x increases, the value of the area also increases and vice versa. This means that the area of the square is directky proportional to its length. Hence we can say YES, the area of a square and the length of its side directly proportional
Answer:
100 sq in
Step-by-step explanation:
No, not proportional
The area of a rectangle is 5/6 square foot. The width is 2/3 foot. How many times greater is the length than the width? Write your answer in simplest form.
Answer:
15/8
Step-by-step explanation:
The area of a rectangle is given as 5/6 square foot.
The width is given as 2/3 foot
But area if a Rectangle = Lenght × width
A = Lenght x width
5/6= Lenght × 2/3
If we make Lenght subject of the formula we have
lenght= (5/6) / (2/3)
length = (5×3)/(6×2)
Lenght= 5/4
To calculate the number of times greater is the length than the width we take the ratio of Lenght and width
Lenght / width = (5/4) / (2/3)
= (5×3)/(4×2)
= 15/8
Hence the number of times greater is the length than the width is 15/8
2x-y=1
x-y=-2
......................................
Answer:
y=5 x=3
Step-by-step explanation:
x-y=-2 move the y over to isolate x
x=-2+y Now plug that in for x in the first equation
2(-2+y)-y=1 Distribute
-4+y=1 Add 4 on both sides
y=5
x-5=-2
x=3
The price P, in dollars, for a large pizza is P = 2n + 7, where n is the number of toppings on the pizza. How many toppings are on a pizza that costs $15?
Answer:
There are 4 toppings on a pizza that costs $15.
Step-by-step explanation:
To find the amount of toppings that are on a pizza that costs $15, you will need to consider that P=15, replace this value on the formula and then, solve for n that is the number of toppings on the pizza:
P=2n+7
15=2n+7
15-7=2n
n=8/2
n=4
According to this, the answer is that there are 4 toppings on a pizza that costs $15.

Given the angle measures of a triangle are 3x + 6 degrees, 4x + 2 degrees and 10x + 2 degrees, determine the 3 angles in this triangle?
Answer:
36,42,102
Step-by-step explanation:
A triangle is 180° total so your equation to find x is:
3x+6+4x+2+10x+2=180°
17x+10=180
17x=170
x=10
to find the individual sides:
3(10)+6=36
4(10)+2=42
10(10)+2=102
to make sure this is right, add 36+42+102. It should equal 180 and it does

Answer:-1
Step-by-step explanation:
the output of a function is the y value while the input is the x value.
so the question is asking what does the y value( output) have to be for the x value( input) to be zero.
since the graph is provided we can just look to see where the x values becomes zero ( the y axis is when all y values are zero)
we then can identify that the y intercept is -1

A piece of string has been used to measure the circumference of a circle. Use a ruler to measure the diameter of the circle and the length of the string to the nearest 1/4 inch
Answer:
The circumference is expressed usingC=2πrStep-by-step explanation:
This problem is on the mensuration of flat shapes, a circle.
The length of the string corresponds to the circumference of the circle.
The lenght of the string can be calculated by using the expression for circumference, if after using the ruler to obtain the diameter "d"
upon measuring the diameter we can further obtain the radius "r"
The expression for the radius is r=d/2 (the radius is half the diameter)
C=2πr
where pi= 3.124 a constant term
Hence Circumference is the same as the length of the string
There are 48 members of the swim team. The ratio of boys to girls is 3:5. How many girls are on the swim tearn? Explain how you found your answer.
Answer:
There are 30 girls
Step-by-step explanation:
The ratio is 3:5 so (3)*(6)= 18 boys , and (5)*(6)=30
30+18=48 members
There were 30 girls in swim team.
We have,
Total Members = 48
Ratio of Boys to Girls= 3:5
So, the number of boys are
= 3/8 x 48
= 3 x 6
= 18
and, the number of girls
= 5/8 x 48
= 5 x 6
= 30
Thus, 30 girls were in swim team.

The University of Washington Huskies tried throwing one of the longest Hail Mary's in history
- about 73 yards. For this pass, the ball's height over time was modeled by the function
h(t) = –16t2 + 64t + 6, where h(t) was the height in feet and t was the time in seconds.
Let's break down whether the Huskies ever had a chance.
1.
73 yards isn't just a long way to throw, it's a long way to run. To give his team the
best chance of running all the way down the field and catching the ball before it hits
the ground, the quarterback (passer) needs to keep the football in the air for a long
time. How long was the ball in the air?
9514 1404 393
Answer:
4.09 seconds
Step-by-step explanation:
The ball is in the air until h(t) = 0. Solving that equation for t, we have ...
0 = -16t^2 +64t +6
t^2 -4t = 3/8 . . . . . . rearrange, divide by 16
t^2 -4t +4 = 4 3/8 . . . add 4 to complete the square
(t -2)^2 = 4.375 . . . . write as a square
t = 2 +√4.375 . . . . . positive square root, add 2
t ≈ 4.09165
The ball was in the air about 4.09 seconds.

-3y+(1)/(5)=(2)/(3)x write in Ax+By=C
Answer:
2/3x + 3y = 1/5
Step-by-step explanation:
-3y + 1/5 = 2/3x (subtract 1/5)
-3y = 2/3x - 1/5 (subtract 2/3x)
-2/3x - 3y = -1/5 (divide by negative 1)
2/3x + 3y = 1/5

You and a group of friends take turns planting 2 trees each at a campsite. After the first person plants 2 trees, there are 12 trees at the campsite. A. Write an equation for the nth term of the arithmetic sequence. Let n represent the position in the sequence and let an represent the number of trees. C. After 8 more people plant trees, how many trees are at the campsite?
Answer:
The equation for the nth term will be;
An = 10 + 2n
After the 9th planter ( 8 more than the initial one); number of trees will be 28
Step-by-step explanation:
After the first person plant two trees, there were 12 trees at the plant sites
What this mean is that initially, they were 12-2 = 10 trees at the plant site
The nth term of the sequence which represents the number of trees given the number of persons that have planted will be;
An = 10 + 2n
Now, after 8 more people planted, since we had one that already planted, the total number of planters is now 9 planters
So using the equation, n will be 9
So ; A9 = 10 + 2(9)
A9 = 10 + 18
A9 = 28
