Answer:
b = 2A+c
Step-by-step explanation:
A = (b-c)/2
Multiplying both sides by 2
=> 2A = b-c
Adding c to both sides
=> 2A+c = b
OR
=> b = 2A+c
What is the measure of an angle that is nine times it’s complement
Answer:
9
Step-by-step explanation:
Assume that the measure of the angle is x
That would mean that the compliment of that angle would be 9x
Two angles are complementary when their sum equals 90
That means x + 9x equals 90.
We can combine x and 9x into 10x, leaving us with 10x=90
Divide both sides by 10
x=9
Simon makes 30 cakes He gives 1/5 of the cakes to sali He gives 10% of the cake to Jane What fraction of 30 does he have left
Answer:
7/10 or 0.7 or 70% left.
Step-by-step explanation:
Since he gives 1/5 of the cake to Sali, he gave 1/5 * 30 = 6 cakes away to Sali. Since 10% is 1/10, he gave away 1/10 * 30 = 3 cakes away to Jane. He has a total of 30 - 3 - 6 = 21 cakes left. 21/30 = 7/10, or 0.7, or 70% left.
Answer: 21/30
Explanation this is because 1/5of 30 is 6 and 10 percent of 30 is 3
6+3=9
30-9=21
Therefore Simon has 21/30 cakes left

Ella finishes school at 3pm. The time on her watch is 14;13. how long is it until Ella finishes school?
Answer:
47 minutes
Step-by-step explanation:
14:13 is 2:13 PM in 12 hour time.
There are 47 minutes left till 3 PM. Ella’s school finishes at 3 PM, so there are 47 minutes left.
Answer:
47 minutes
Step-by-step explanation:
3pm is the 12 hour time zone which can be converted to 15:00 in the 24 hour time zone.
So, the easiest way is to subtract 13 minutes (14:13) by an hour. Our result is 47 minutes (60-13).
Hope this helps and please mark as the brainliest.
Miguel can use all or part of his $25 gift card to make a music purchase. Each song costs $1.50, and there is a $1.00 per account activation fee. Which inequalities can represent this situation if m is the number of songs he can buy? Select two options. 1 + 1.5 m less-than-or-equal-to 25 1 + 1.5 m greater-than 25 25 greater-than 1 + 1.5 m 1 + 1.5 m less-than 25 25 greater-than-or-equal-to 1 + 1.5 m
Answer:
1 + 1.5 m less-than-or-equal-to 25
25 greater-than-or-equal-to 1 + 1.5 m
Step-by-step explanation:
Available amount $25
Cost of a song= $1.5
One of fee= $1
Number of songs= m
25 ≥ 1+1.5mor
1 + 1.5m ≤ 25is the required inequality
-----------
Correct answer choices:
1 + 1.5 m less-than-or-equal-to 25 25 greater-than-or-equal-to 1 + 1.5 mAnswer:
1.00+1.50m ≤ 25 (1+1.5 m less than or equal to 25)
OR
25 ≥ 1.00+1.50m (25 greater than or equal to 1+1.5m)
Step-by-step explanation:
Activation Fee = $1.00
Cost of each song = $1.50
Since we are given that he can buy m songs .
So, Cost of m songs = $1.50 m
So, total cost = Activation charge + Cost of m songs = $1.00+$1.50 m
Since we are also given that Miguel can use all or part of his $25 gift card to make a music purchase.
So, the inequality becomes :
=> 1.00 + 1.50m ≤ 25
=> 1.50m ≤ 25-1
=> 1.50m ≤ 25
=> m ≤ 25/1.50
=> m ≤ 16
Hence the inequality that can represent the situation is
1.00+1.50m ≤ 25
OR
25 ≥ 1.00+1.50m

The answer is : 0.12 x 600 = 72 or the equivalent : 600 x 12/100 = 72
Your list of possible answers ended up a bit scrambled for me to identify which one it is.
Step-by-step explanation:
The number of black and white pictures can be obtained by multiplying the total number of pictures taken (600) by the decimal form of 12% = 12/100 = 0.12. That is:
Number of B&W pictures = 0.12 x 600 = 72

can someone help me to find tsa of entire solid ?
Step-by-step explanation:
Radius is same in both cones....
Slant height of lower cone = 50 cm ( by applying Pythagorean theorem )
TSA of the lower cone = 22/7 × 14 × ( 14 + 50 )
= 2816 cm^2
Total height of the solid = 52.8 cm
Height of the upper cone = 52.8 - 48 = 4.8 cm
TSA of the upper cone = 22/7 × 14 × ( 14 + 4.8 )
= 827..2 cm^2
TSA of the solid = 2816 + 827.2 = 3643.2 cm^2
An AP has 15 terms and a common
difference of - 3. Find its first and last terms
if its sum is
b 15
d -120
a 120
Answer:
Step-by-step explanation:
Sum =n/2{2a+(n-1)d
When sum=15 and d=-3
15=15/2{2a+(15-1)-3}
15=7.5{2a+(14)-3}
15=7.5{2a+(-42)}
15=7.5(2a-42)
15=15a-315
15+315=15a
330=15a
a=330/15
=22
a=22
Last term=a+(n-1)d
=22+(15-1)-3
=22+(14)-3
=22-42
= -20
When sum=120
Sum=n/2{2a+(n-1)d
120=15/2{2a+(15-1}-3
120=7.5{2a+(14)-3}
120=7.5{2a+(-42)}
120=7.5(2a-42)
120=15a-315
120+315=15a
435=15a
a=435/15
=29
a=29
Last term=a+(n-1)d
=29+(15-1)-3
=29+(14)-3
=29-42
= -13
When sum= -120
Sum=n/2{2a+(n-1)d
-120=15/2{2a+(15-1)-3
-120=7.5{2a+(14)-3}
-120=7.5{2a+(-42)}
-120=7.5(2a-42)
-120=15a-315
-120+315=15a
195=15a
a=195/15
a=13
Last term=a+(n-1)d
=13+(15-1)-3
=13-42

the radius of wheel of a bicycle is 40 cm. taking pie =3.14, a)find tthe circumference of the wheel.b) find the distance covered by the bicycle in 200 complete revolution of the wheel.please ans this question. i beg you
Answer:
a)=251.2 cm b)=50240 cm
Step-by-step explanation:
a) The formula for calculating the circumference of a circle is c=d*pie, where D is the diameter of the circle.
Therefore, C = 2 * 40 * 3.14 = 251.2 cm
b) The distance covered by 200 revolutions of the wheel is 200 times the circumference, 200*251.2=50240 cm.So to think about this we can assume that there is a point A on the wheel, the distance that point A travels when it rotates 200 times.
Mr. Mole left his burrow and started digging his way down.
A represents Mr. Mole's altitude relative to the ground (in meters) after t minutes.
A= -2.3t – 7
How fast did Mr. Mole descend?
Answer:
He's descending at a pace of 2.3 meters per minute.
Step-by-step explanation:
This is because the equation shows us the slope or the speed he's going at.
A= -2.3t - 7
A= Altitude
-2.3 = Slope
- 7 is his starting altitude in meters
But every minute, t, he is going down 2.3 meters. It's easier to think about if you consider, A = y, and, t = x. Now you have the equation, y = -2.3x - 7.
And you graph it to see the progression in slope.

Which system of equation is shown?
Answer:
B. y>x y>2
Step-by-step explanation:
Solve this by plugging in any coordinates (x, y) that fall into the orange space on the graph.
Plug into each answer choice. Let's say I picked the coordinate (0,5). I would then look at answer choice A and see if plugging in the values of x and y make the system of equation statements true. For A, my equations would be 5>0 and 5<2. The first statement is true, however, the second is false, so A is not the answer.
Do this for each answer choice until you find the one with true statements only. After doing this, you'll find that answer choice B is the only one in which both statements are correct.

The perimeters of the square and the regular pentagon are equal. A square with side lengths of 3x + 3. A pentagon with side lengths of x + 8.
Answer:
60
Step-by-step explanation:
Since the perimeters are equal then:
(3x + 3) * 4 = (x + 8) * 5
12x + 12 = 5x + 40
7x = 28
x =4
Perimeter of square = (3*4 + 3) * 4 =
(12 + 3) * 4 = 60
Perimeter of pentagon = (4 + 8) * 5 =
(12) * 5 = 60
The answer is 60
Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by , where is the number of hours since 10 AM, .
Complete Question:
Suppose a local vendor charges $2 per hot dog and that the number of hot dogs sold per hour is given by [tex]x(t) = -4t^2 + 20t + 60[/tex], where is the number of hours since 10 AM:
a) Find an expression for the revenue per hour as a function of x, R(x)
b) Find and simplify, R(x(t))
Answer:
a) R(x) = 2x
b) [tex]R(x(t)) = -8t^2 + 40t + 120[/tex]
Step-by-step explanation:
a) This is a very trivial exercise.
[tex]x(t) = -4t^2 + 20t + 60[/tex]
The number of hot dogs sold per hour is given by x
Charge per hot dog = $2
An expression of revenue per hour,R, as a function of the number of hot dogs sold per hour, x, is therefore: R(x) = 2x
b) [tex]x(t) = -4t^2 + 20t + 60[/tex]
R(x(t)) = 2(x(t))
[tex]R(x(t)) = 2(-4t^2 + 20t + 60)\\R(x(t)) = -8t^2 + 40t + 120[/tex]
