Answer:
Step-by-step explanation:
how many shapes of size A are in B ?
I counted 9.5
then just multiply the count * the size of A
got it?
Step-by-step explanation:
area of shape A = 3cm²
number of A shape in shape B = 9 and half
1 shape A = 3cm²
9 shape A = 3×9 = 27cm²
1 half shape A = 3 ÷ 2 = 1.5cm²
area of shape B = 27cm² + 1.5cm² = 28.5cm²

Answer:
A = 54.11 unit²
Step-by-step explanation:
Given that :
A = θ/360 * πr²
A = 62/360 * π(10)²
A = 0.1722222 * π * 100
A = 54.105206
A = 54.11 unit²
determine the value of x if the sequence 2x-1; 3x+1; 7x-1; is a geometric sequence
Answer:
x=0 or x=3
Step-by-step explanation:
Since it is a geometric sequence, that means term divided by previous term is the same number. Let's call that number, r.
That means we have:
(3x+1)/(2x-1)=r
(7x-1)/(3x+1)=r
Since both of the ratios are the same, then we have
(3x+1)/(2x-1)=(7x-1)/(3x+1)
Cross multiply:
(3x+1)(3x+1)=(2x-1)(7x-1)
Distribute:
9x^2+3x+3x+1=14x^2-2x-7x+1
Combine like terms:
9x^2+6x+1=14x^2-9x+1
Subtract 1 on both sides:
9x^2+6x=14x^2-9x
Subtract 14x^2 on both sides
Add 9x on both sides
-5x^2+15x=0
Factor -5x:
-5x(x-3)=0
-5x=0 when x=0 since -5(0)=0
x-3=0 when x=3 since 3-3=0
It is possible for a system of linear equations to have exactly 2 solutions.
Answer:
Number of Solutions
Most linear systems you will encounter will have exactly one solution. However, it is possible that there are no solutions, or infinitely many. (It is not possible that there are exactly two solutions.) The word unique in this context means there is a solution, and it's the only one.

Mai’s pencil is 24 cm long. She sharpens it, and it loses 1/8 of its length. How long is her pencil now?
Answer:
It is 21 cm long
Step-by-step explanation:
1/8 of 24 is 3, so you would subtract 3 from 24. 3*8=24.

Kieran buys a car for $8000
The following year he sells the car for $7500
Find the percentage loss.
Answer:
6.25% I think
Step-by-step explanation:
If Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.
What is percentage?A percentage is the number or ratio which is expressed as a fraction of 100.
How to calculate percentage?We have been given the buying value=$8000
Selling value=$7500
Loss=Buying value- selling value
=8000-7500
=$500
Percentage of loss=loss/ buying value*100
=500/8000*100
=6.25%
If we want to check our answer then we can multiply our percentage with the buying value.
=8000*6.25%
=500
Hence if Kiara sells car at $7500 and it is of $8000 then she is having a loss of 6.25%.

I'm 3 times younger than my mom but 3 times older than my younger brother. Mom is older than my younger brother by 40 years. how old am I?
Given:
I'm 3 times younger than my mom but 3 times older than my younger brother.
Mom is older than my younger brother by 40 years.
To find:
How old am I.
Solution:
Let x be the age of the younger brother.
I'm 3 times older than my younger brother. So, my age is 3x.
I'm 3 times younger than my mom. So, she is 3 times older than me and her are is 3(3x)=9x.
The difference between the age mother and younger brother is 40 years.
[tex]9x-x=40[/tex]
[tex]8x=40[/tex]
Divide both sides by 8.
[tex]x=\dfrac{40}{8}[/tex]
[tex]x=5[/tex]
Now,
My age [tex]=3x[/tex]
[tex]=3(5)[/tex]
[tex]=15[/tex]
Therefore, I'm 15 years old.

Mary always saved 45% of his salary. When his salary decreased by 20% in April, his savings decreased by $180.
How much was Mary’s salary before the decease?
Answer:
Step-by-step explanation:
Answer:
Is Mary a guy? :|
Step-by-step explanation:
I did this by just a good guess , not really the right way
2000*.45=900 ( 900 is the old savings)
2000*.2 =400 ( how much her salary went down by )
2000-400=1600 ( new salary )
1600*.45 = 720 ( 45% of new salary is new savings
900-720=180 ( change in savings is 180 , the amount the question asks for)
Mary's old salary was 2,000

10. In how many ways can a student select 7 out of 10 questions to work on an exam
Answer:
Step-by-step explanation:
7C10 = 10!/(7!)(10-7)!
7C10 = 10!/(7!)(3!)
7C10 = (10 x 9 x 8 x 7)/(7 x 6 x 5)(6)
7C10 = (10 x 9 x 8)/6
7C10 = 720/6
7C10 = 120

Write an equation in slope-intercept form that represents the data.
Answer:
1) y = 5x + 100
2) y = -10x + 375
Step-by-step explanation:
The slope intercept form of an equation is expressed as y = mx+c
m is the slope
c is the intercept
1) Using the coordinate points (0,100) and (1, 105)
slope m = 105-100/1-0
m = 5/1
m = 5
Substitute m = 5 and (0,100) into the formula y = mx+c
100 = 5(0)+c
100 = 0 + c
c = 100
The required equation is y = 5x + 100
2) Using the coordinate points (0,375) and (5 325)
slope m = 325-375/5-0
m = -50/5
m = -10
Substitute m = -10 and (0,375) into the formula y = mx+c
375 = -10(0)+c
375 = 0 + c
c = 375
The required equation is y = -10x + 375
is 3/4 equivalent to 27/36
Answer:
yes , 27/36=3*9/4*9=3/4 both the number 27 and 36 can be multiplied by 9 and can be reduced to its lowest form i.e.
Let the measure of Arc B C D = a°. Because Arc B C D and Arc B A D form a circle, and a circle measures 360°, the measure of Arc B A D is 360 – a°. Because of the ________ theorem, m∠A = StartFraction a Over 2 EndFraction degrees and m∠C = StartFraction 360 minus a Over 2 EndFraction degrees. The sum of the measures of angles A and C is (StartFraction a Over 2 EndFraction) + StartFraction 360 minus a Over 2 EndFraction degrees, which is equal to StartFraction 360 degrees Over 2 EndFraction, or 180°. Therefore, angles A and C are supplementary because their measures add up to 180°. Angles B and D are supplementary because the sum of the measures of the angles in a quadrilateral is 360°. m∠A + m∠C + m∠B + m∠D = 360°, and using substitution, 180° + m∠B + m∠D = 360°, so m∠B + m∠D = 180°.
What is the missing information in the paragraph proof?
Answer:
A. Inscribed Angle
Step-by-step explanation:
Because the angles are inscribed in the circle, the angle lie on arcs which mean that the angles have to add up to 360 degrees just like a circle is 360 degrees, making it a quadrilateral that is inscribed!
The missing information in the paragraph proof should be considered as the Inscribed Angle.
What is Inscribed Angle?In terms of geometry, an inscribed angle should be the angle that should be created in the interior of a circle at the time when two chords intersect on the circle. Since the angles should be inscribed in the circle so here the angles should be added up to the 360 degrees same as like the circle also at the same time it should make the quadrilateral
Therefore, The missing information in the paragraph proof should be considered as the Inscribed Angle.
