Answer:
90°Step-by-step explanation:
Sum of angles in triangle equals to 180°
∠R = 180° - (∠S + ∠T)∠R = 180° - (29° + 61°) = 180° - 90° = 90°the value of a second-hand car is £8000
Each year it loses 20% of it value at the start of this year. work out its value in 5 years time.
pls show working out
I will mark brainest and rate 5 stars
Answer:
£2,621.44
Step-by-step explanation:
Original cost of car = £8000
If it looses 20% of its value yearly
Value at the end of first year
80% * 8000
= 0.8 * 8000
= 6400
Value at the end of second year
80% * 6400
= 0.8 * 6400
= 5120
Value at the end of third year
80% * 5120
= 0.8 * 5120
= 4096
Value at the end of fourth year
80% * 4096
= 0.8 * 4096
= 3,276.8
Value at the end of fifth year
80% * 3,276.8
= 0.8 * 3,276.8
= 2,621.44
Hence the value in 5 years time will be £2,621.44
the value of a second hand car is £8000. Each year it loses 20% of its value at the start of this year. work out its value in 5 year time.

Step-by-step explanation: The opposite of Multipication is division so divide 84 by 12
Answer:
k=7
Step-by-step explanation:
Call me weird but I love these types of questions.
Ok to solve this here's what you need to do.
Your solving for k right?
So make an equation.
Product is the result of multiplication so 12 and k would be 12k.
It needs to equal 84 so 12k=84
Now you need to get rid of 12.
You need to use the opposite operation as the number your trying to get rid of. In this case it would be division.
[you do not divide the x because you need it alone on one side]
So 12k divided by 12 = 84 divided by 12
12k/12 is k because a number divided by itself is 1.
84/12 is 7.
that leaves us with k=7
Thats it!

Karen purchased a prepaid phone card for $15. Long-distance calls cost 19 cents a minute using this card. Karen used her card only once to make a long-distance call. If the remaining credit on her card is $12.91, how many minutes did her call last?
Answer:
I am pretty sure the answer is 11 minutes and the cost was $2.09
Step-by-step explanation:
Ihope this helps you:)
Step-by-step explanation:
Ok so we start with $15 now the remaining amount is $12.91, so let's substract
15.00 - 12.91 = 2.09
Alright now I must work with this number, since every minute used on the call is 19 cents, i must divide 2.09 to see how many 19 cents fit into this number
2.09 / 0.19 = 11
So she lasted talking or in this call 11 minutes....
I hope this helps!

Answer:
The correct options are;

Step-by-step explanation:
The two column proof is presented as follows;
Statement [tex]{}[/tex] Reason
1. ∠1 and ∠2 are supplementary [tex]{}[/tex] Given
∠1 and ∠3 are supplementary [tex]{}[/tex]
2. m∠1 + m∠2 = 180° [tex]{}[/tex] (1) Definition of supplementary angles
m∠1 + m∠3 = 180°
3. (2) m∠1 + m∠2 = m∠1 + m∠3 [tex]{}[/tex] Transitive Property
4. (3) m∠2 = m∠3 [tex]{}[/tex] Subtraction property of equality
5. ∠2 ≅ ∠3 [tex]{}[/tex] (4) Definition of congruent angles
Given that angles ∠1 and ∠2 are supplementary, we have, ∠1 + ∠2 = 180°
Given that angles ∠1 and ∠3 are also supplementary, we also have, ∠1 + ∠3 = 180°
∴ ∠1 + ∠2 = 180° = ∠1 + ∠3
∠1 + ∠2 = ∠1 + ∠3
∠1 + ∠2 - ∠1 = ∠1 + ∠3 - ∠1
∴ ∠2 = ∠3
∴ ∠2 ≅ ∠3, by definition of congruent angles.

Avery is making a necklace for her mothers birthday. She uses 1 1/20 strings of black beads and 1 4/5 more strings of gray beads than black beads. How many strings of gray beads did she use?
.
Answer:
She used 2 17/20 strings of grey beads
Step-by-step explanation:
Here, we want to know the number of grey beads used
To calculate this, we simply add up the black beads number with the number of grey beads
Mathematically, that will be;
1 1/20 + 1 4/5
= 21/20 + 9/5
= (21 + 36)/20
= 57/20 = 2 17/20

Choose the graph below that correctly represents the equation 3x + 9y = −18. (5 points)
the line through the points negative 6 comma 0 and 0 comma 2
the line through the points negative 6 comma 0 and 0 comma negative 2
the line through the points negative 2 comma 0 and 0 comma 6
the line through the points negative 2 comma 0 and 0 comma negative 6
Answer:
the line through the points negative 6 comma 0 and 0 comma negative 2
Step-by-step explanation:
Rewrite the equation to something you are familiar with such as the slope intercept form; y = mx + b. This means you need to solve for y.
3x + 9y = -18 --- divide everything by 3.
x + 3y = -6
3y = -6 - x
y = -2 - 1/3x
your slope is -1/3 and your y intercept is - 2.
remember, y-intercept is when x = 0. therefore, when x = 0, y = -2.
write as an ordered pair (0, -2). the only option that has (0, -2) is the second one.
Therefore, the line through the points negative 6 comma 0 and 0 comma negative 2.

express cos6mcos2m as a sum or difference
Given :
An expression (cos 6m)(cos 2m) .
To Find :
We need to express it in terms as sum or difference.
Solution :
We know,
cos( A + B ) = cosA cos B - sin A sin B
cos( A - B ) = cosA cos B + sin A sin B
Adding both the equations we get :
2cos A cos B = cos( A + B) + cos( A - B )
or
cos A cos B = cos( A + B) + cos( A - B )/2
Putting value of A = 6m and B = 2m in above equation, we get :
(cos 6m)(cos 2m) = cos( 6m + 2m ) + cos( 6m - 2m )/2
(cos 6m)(cos 2m) = cos(8m) + cos(4m)/2
Hence, this is the required solution.
Penelope leaves her house. For eight minutes, she drives to the store at a rate of one block per minute. Then, she stops for five minutes to shop in the store. Finally, she drives back to her house at a rate of four blocks every three minutes. Write the equation to model Penelope's trip to the store.
Answer:
T = 8 + 5 + 6
Step-by-step explanation:
Since it took Penelope 8 minutes to drive to the store at a rate of 1 block per minute then that means the store was 8 blocks away. That being the case if she drives back home from the store at 4 blocks every 3 minutes that would mean that she took 6 minutes (4+4 = 8) to get back home. Using this data we can create the following equation model to calculate the total time of the trip.
T = 8 + 5 + 6
Find the perimeter of triangle ABC. Approximate to the nearest whole unit.
Answer: 16 units
Step-by-step explanation: adding the perimeter sides to get the perimeter of triangle ABC would be 4.1+6.1+5.8 = 16
Answer:
16
Step-by-step explanation:
AC = 6.1
CB = 5.8
BA = 4.1
Use whole number approximations for the three side lengths.
AC = 6
CB = 6
BA = 4
perimeter = AC + CB + BA = 6 + 6 + 4 = 16

Rita filled 2/5 of a jug with fruit juice. She then added 200 ml of milk to make a milkshake. At this stage, the ratio of the fruit juice to milk is 3:2
how much more liquid can the jug hold?
a)250 ml
b)300 ml
c)400 ml
d)450 ml
Answer:
250ml understand the concept please
The jug can hold 250 ml more liquid.
Let the jug can hold x ml liquid.
Given Rita filled 2/5 of a jug with fruit juice.
So, the amount of fruit juice is = 2/5 of x = 2x/5.
Then she added 200 ml milk.
Given the ratio of the fruit juice to milk is 3:2.
So,
[tex]\frac{2x}{5}:200=3:2\\\frac{\frac{2x}{5} }{200}=\frac{3}{2}\\2( \frac{2x}{5})=600\\\frac{4x}{5}=600\\ x=\frac{600*5}{4}\\x=750[/tex]
So the amount of fruit juice = [tex]\frac{2}{5}*750=300[/tex] ml.
Total amount of fruit juice and milk = 300+200=500 ml.
So the jug will hold = 750 - 500 =250 ml more.
