What single decimal multiplier would you use to increase by 2% followed by a 1% increase?
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

Answer:
(x, y, z) = (124, 112, 42)
Step-by-step explanation:
Opposite angles in an inscribed quadrilateral are supplementary, so ...
y° = 180° -68° = 112°
The angle marked 71° subtends an arc twice that measure, so ...
2(71°) = 100° +z°
z° = 142° -100° = 42°
The angle marked y° subtends an arc twice that measure, so ...
2y° = 100° +x°
x° = 2(112°) -100° = 124°
Choose the model that represents the same function as the graph of f(x)
Answer:
x × 1/2 - 3
Step-by-step explanation:
in slope intercept form an equation is written in y=mx+b where m is the slope and b is the y intercept
from the graph you can see the line goes up 1 and right 2, up 1 right 2, etc. that means the slope is positive 1/2
the line cross the y access at -3, therefore the y intercept is -3
so
[tex]y = \frac{1}{2} x - 3[/tex]
What is the approximate volume of a sphere with a diameter of 20 feet? Use 3.14 for it.
Answer:
4,188.79 and when its rounded its 4,188.8
Step-by-step explanation:
Volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.
What is Three dimensional shape?Three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given,
sphere with a diameter of 20 feet
Diameter is two times of radius
Diameter=2Radius
Radius =Diameter/2
Radius = 20/2=10 feet.
Volume of sphere=4/3πr³
π=3.142
Volume of sphere=4/3(3.142)(10)³
=4/3×3.142×1000
=4189.33 cubic feet.
Hence, volume of a sphere with a diameter of 20 feet is 4189.33 cubic feet.

Step-by-step explanation:
The key here is she wants to make "at least", implying that you have an inequality. If she cecks the house 4 times plus the 2 overnight stays then she will have exactly 150, so that is the least needed to reach her goal. So at least automatically turns it into an inequality.

Answer:
A = 28.26 cm², P = 38 units, A = 20 units², C = 43.96 units
Step-by-step explanation:
1) Our area of a circle is πr². Since our r = 3 cm, we can just substitute for r.
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 cm², like in your work.
2) Our formula for perimeter is 2l + 2w. We substitute for l = 12 and w = 7.
P = 2l + 2w
P = 2(12) + 2(7)
P = 24 + 14
P = 38 units
3) The formula for a triangle's area is A = [tex]\frac{1}{2}[/tex]bh, so we substitute for b = 10 and h = 4.
A = [tex]\frac{1}{2}[/tex] bh
A = [tex]\frac{1}{2}[/tex] (10)(4)
A = [tex]\frac{1}{2}[/tex] (40)
A = 20 units²
4) Circumference is 2πr, and we substitute for r = 7.
C = 2πr
C = 2(3.14)(7)
C = (3.14)(14)
C = 43.96 units

Andy is buying a car.
He negotiated a 7% decrease on a £6 500 car.
He will pay the full balance in 12 equal monthly payments.
Calculate the amount paid each month.
Answer:
£503.75
Step-by-step explanation:
Andy is buying a car.
Step 1
We calculate the decrease
He negotiated a 7% decrease on a £6 500 car.
Decrease = 7% × £6500
= $455
Step 2
We calculate the new price of the car.
= Old price - Decrease
= £6500 - £455
= £6045
Step 3
We calculate the amount he pays every month.
We are told that:
He will pay the full balance in 12 equal monthly payments.
Andy's monthly payments =
New price/12 months
= £6045/12
= £503.75
Therefore, the amount he would be paying each new month = £503.75

Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle. If the distance from balloon A to the ground is 1,400 feet, how far
is balloon B from balloon A? Round your answer to the nearest whole number
Balloon A
Balloon B
Ground
Charlie
999 feet
1,005 feet
1,052 feet
1,102 feet
Answer:
Step-by-step explanation:
Assume that B is directly above A.
x = horizontal distance between Charlie and balloons
= 1400/tan(60°)
altitude of B = x·tan(82°) ≅ 5751 ft
distance between A and B = 5751-1400 = 4351 ft, which doesn't fit any of the choices. So my initial assumption was incorrect.
Is there any other information? A picture?
The distance between balloon A and balloon B is 1005 feet if Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle option second 1005 feet is correct.
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
We have:
Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle
In right angle triangle ACD,
tanx = AC/CD
tan60 = 1400/CD
CD = 808.3
In triangle BDE,
tany = BE/DE
tan82 = 1400/DE
DE = 196.8
The distance between balloon A and balloon B:
= CD + DE
= 808.3 + 196.8
= 1005 Feet
Thus, the distance between balloon A and balloon B is 1005 feet if Charlie is watching hot air balloons Balloon A has risen at a 60° angle Balloon B has risen at an 82 angle option second 1005 feet is correct.

Which equation represents the line that is parallel to y= 3 and passes through (-2,-8)?
A.x = -2
B.x= 3
C.y=-8
D. y= 3x - 2
Answer:
Now, as you might recall, two lines are parallel when they are always the same distance apart and never intersect. y= -8 is parallel to y=3 and it passes through the point (-2, -8). The equation of this line is y= -8.

The inside of a rectangular swimming pool is going to be painted. The pool is 8 feet wide, 25 feet long, and 5 feet deep.
What is the surface area of the five faces to be painted?
Answer:
total area = 530 ft^2
Step-by-step explanation:
bottom = 8 x 25 = 200 ft^2
2 sides = 8 x 5 x 2 = 80 ft^2
2 other sides = 25 x 5 x 2 = 250 ft^2
200 + 80 + 250 = 530 ft ^2

b = 54 °
plz mark my answer as brainlist plzzzz.
hope this will be helpful to you.☺️
Answer:
a = 18°
[tex] b= 108\degree [/tex]
Step-by-step explanation:
ABCD is a rhombus.
AC and BD are its diagonals
Diagonals of a rhombus bisects at right angles.
Therefore,
5a = 90°
a = 90°/5
a = 18°
2a = 2*18° = 36°
Diagonals of a rhombus bisects the opposite angles.
Therefore,
[tex] m\angle ADC = 2(2a)[/tex]
[tex] m\angle ADC = 2\times 36\degree [/tex]
[tex] m\angle ADC = 72\degree [/tex]
[tex] m\angle ADC+m\angle DCB= 180\degree [/tex]
(Adjacent angles of a rhombus are supplementary)
[tex] 72\degree+b= 180\degree [/tex]
[tex] b= 180\degree-72\degree [/tex]
[tex] b= 108\degree [/tex]
