Answer:
Suppose that you have an initial quantity A.
If you have an increase of X%, the new quantity (NQ) is written as:
NQ = A + A*(X%/100%) = A*(1 + X%/100%).
Now, if we have an increase of 2% then:
NQ = A*(1 + 2%/100%) = A*(1 + 0.02)
And no we have another increase of 1%, then:
NQ = (A*(1 + 0.02))*(1 + 1%/100%) = A*(1 + 0.02)*(1 + 0.01) = A*1.0302
The single decimal multiplier that you can use to increase by 2% followed by a 1% increase is 1.0302
Katlin is choosing between two circular wall clocks one has the radius of 5 inches while the other one has a radius of 6 inches.How much more wall space will the clock with a radius of 6 inches cover?
Plz help i dont get any of these type of questions T-T
Answer:
Exact: [tex] 11 \pi~in.^2 [/tex]
Approximate: [tex] 34.6~in.^2 [/tex]
Step-by-step explanation:
The spaces the clocks occupy on the wall are the areas of the clocks.
The clocks are shaped like circles, so use the formula for the area of a circle to find the two areas. Then subtract the smaller area from the larger area.
[tex] A_{circle} = \pi r^2 [/tex]
Larger clock, r = 6 in.
[tex]A_{large~clock} = \pi \times (6~in.)^2 = 36 \pi ~in.^2 = 113.1~in.^2[/tex]
Smaller clock, r = 5 in.
[tex]A_{small~clock} = \pi \times (5~in.)^2 = 25 \pi ~in.^2 = 78.5~in.^2[/tex]
Difference in areas:
Exact: [tex] 36 \pi~in.^2 - 25 \pi~in.^2 = 11 \pi~in.^2 [/tex]
Approximate: [tex] 113.1~in.^2 - 78.5~in.^2 = 34.6~in.^2 [/tex]
pls help me with this question
Answer:
height = 12 feet
Step-by-step explanation:
r (radius of circle) = 7 ft
pi = 3.14 (in this context)
v = 1/3 * [tex]πr^{2}[/tex] (or pi * radius squared) * h
r squared = 49 ft
v = 1/3 3.14 * 49 * h
v = 1/3 153.86 * h
3v = 153.86 * h
v = 196π
v = 615.44
3v = 1,846.32
1,846.32 = 153.86 * h
h = 12 ft.

Find x in the diagram.
Answer:
50
Step-by-step explanation:
The angle left of x added to 140 must be 180 as it is along a line so is 40.
We now have 40 + 90 + x = 180 so x = 50
work out the size of angle x
Answer:
36
Step-by-step explanation:
Answer:
x = 66
Step-by-step explanation:
We know that the sum of all the angles inside a triangle is 180 degrees
x + 79 + 35 = 180
x = 180 - 79 - 35
x = 66

A? Round your answer to the nearest tenth of a meter.
Answer:
130.5
Step-by-step explanation:
The solution is, the value of x is approximately 116.5 meters.
What is trigonometry?Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.
here, we have,
We are given the following information
From this picture, we want to find the vaule of x. To so, we will use the sine law. to solve this problem.
The sine law relates the sine of the angles of the triangle and the length of the opposite sides of the triangle. If we have a triangle of the form
Then,the sine law states that
sinA/a =sinB/b =sinC/c
Which is equivalent to
a/sinA = b/sinB = c/sinC
In our case, we are given the measure of angles A and B and missing the measure of angle C. Also, we are given the measure of side c. If we apply the sine law to the given triangle we have
x/ sin 35 = 200/ sin 80
So, first we need to identify the value of C. To do so, we will use the following fact:
The sum of the inner angles of a triangle is 180°.
Then, we have the following equation
65 +35 +C = 180
If we operate on the left side, we get
100+C = 180
So, by subtracting 100 from both sides, we get
C= 80
So, if we replace the value of C in the equation we had, we get
x/ sin 35 = 200/ sin 80
If we multiply both sides by sin(35) we get
x = 200* sin 35/ sin80
so, using a calculator we get
x = 116.5
so the value of x is approximately 116.5 meters

What is the
length and the base.
The height of a triangle is 2m more than the base. The area is 17.5 m^2.
Answer: 5 m
Step-by-step explanation:
Double the area to get 35. then think what two number multiply to get 35 that are also 2 apart. 7 x 5. So 7 is the height and 5 is the base.
Check answer: A = 1/2xbxh
A = 1/2 x 7 x 5
A = 1/2 x 35
A = 17.5 sq m

Write an equation of the line that passes through the given point and is parallel to the given line.
(2, -3); y = –5
Answer:
y = -3
Step-by-step explanation:
The given line is a horizontal line thru -5 on the y-axis.
Your line is parallel to y = -5, hence is also a horizontal line and passes thru (2, -3). Since -3 is the y-coordinate of that point, y = -3 is the equation of the line you are looking for.

What is the perimeter of JKL?
Answer:
The perimeter of JKL is 60 units.
Step-by-step explanation:
The two tangents of a circle formed by a vertex outside the circle will always be the same distance, this means that JA = JB = 13, LA = LC = 7, and KB = KC = 10. JL = JA + LA = 20, KL = LC + KC = 17, and JK = JB + KB = 23. So the perimeter of triangle JKL is 20 + 17 + 23 = 60 units.

Step-by-step explanation:
Points A, B, C, and D are vertices of a square. Point E is inside the square. Explain how to tell whether point E is closer to A, B, C, or D.
Answer:
To determine if a point E inside a square is closer to any of the vertices of the square we have to determine the length of the diagonals between the point E and the vertices of the square i.e. AE, BE, CE, DE
The diagonal can be determined by applying Pythagorean's theorem

what is 2.4 rounded to the nearest tenth
Answer:
2
Step-by-step explanation:
If the tenth place has a number under 5, round down. (2)
If the tenth place is 5 or more, roundup. (3)
The solution for the number 2.42 rounded to the nearest tenth is 2.4
Used the concept of rounding numbers which states that,
When you round a number to a certain digit, you have to check the value of the digit before the place you want to round off to.
1. If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
2. If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down.
Here, the question said the nearest tenth,
The number to round is 2.42
Clearly, the number 2 placed in the hundredth place is less than 5, so round the number down.
That is 2.42 ≈ 2.4
Therefore, the solution is 2.4

Jaylen will deposit $1,750 in an account that earns 6% simple interest every year. His best friend, Eli, will deposit $1,600 in an account that earns 8.5% interest compounded annually. The deposit will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Compare and contrast the two friends’ account after 5 years
Answer:
Jaylen- 2275
Eli- 2405.85
Jaylen
1750 x 0.06 x 5 =525
525 + 1750 = 2275
He makes 525 simple interest in those 5 years so you add that to the initial amount, to find his total after 5 years.
Eli
A= 1600(1+0.085)^5
1600(1.085)^5
