Wil has a coin collection and is currently adding 9 coins per day to his existing number of coins in his collection.After 22 days he has a total of 218 coins. How many coins will he have after 36 days?
Answers
Answer:
344
Step-by-step explanation:
Number of coins added per day in the collection = 9
Number of coins in the collection after 22 days = 218
To find:
Number of coins in the collection after 36 days.
Solution:
First of all, let us find how many coins did he have initially.
Let the number of coins present initially with Wil = [tex]x[/tex]
Number of coins added per day = 9
Number of coins added after 22 days = 22 [tex]\times[/tex] 9 = 198
Therefore,
[tex]x + 198 = 218\\\Rightarrow x = \bold{20}[/tex]
Number of coins present with Wil initially = 20
Number of coins added after 36 days = 36 [tex]\times[/tex] 9 = 324
Total number of coins after 36 days = Number of coins present initially with Will + Number of coins added = 324 + 20 = 344
Karen ordered 2 hot dogs for $1.25 each, a serving of onion rings for $2.99, and a drink for $0.98. Karen pays with a $10.00 bill. If tax is included in the prices, how much change will Karen receive?
Answers
Answer:
$3.53
Step-by-step explanation:
hot dogs = $1.25 each
2 hot dogs = 1.25 × 2
= $2.50
A serving of onion rings = $2.99
Drink = $0.98
Total amount with Karen = $10.00
how much change will Karen receive?
Total cost = 2 hot dogs + A serving of onion rings + Drink
= $2.50 + $2.99 + $0.98
= $6.47
Karen's change = Total amount with Karen - Total cost
= $10.00 - $6.47
= $3.53

Answer:
2
Step-by-step explanation:
We will use the KFC method to figure out the answer:
3/5 ÷ 2/1
We keep the first fraction
3/5 ÷ 2/1
Flip the last fraction (swap the numbers)
3/5 ÷ 1/2
Change the sign (to a multiplication symbol)
3/5 x 1/2
Then, finally, to solve for the answer, we multiply across (3 x 1 and 5 x 2).
3 x 1 = 3
5 x 2 = 10
The answer is 3/10 because it cannot be simplified any further.

solve for x. 3(x- 4)=15x
Answers
Answer:
x=-1
Step-by-step explanation:
3(x−4)=15x
Use the distributive property to multiply 3 by x−4.
3x−12=15x
Subtract 15x from both sides.
3x−12−15x=0
Combine 3x and −15x to get −12x.
−12x−12=0
Add 12 to both sides. Anything plus zero gives itself.
−12x=12
Divide both sides by −12.
x=
−12
12
Divide 12 by −12 to get −1.
x=−1
Answer:
[tex]3(x- 4)=15x[/tex]
[tex]3x-12=15x[/tex]
[tex]3x-12+12=15x+12[/tex]
[tex]3x=15x+12[/tex]
[tex]3x-15x=15x+12-15x[/tex]
[tex]-12x=12[/tex]
[tex]\frac{-12x}{-12}=\frac{12}{-12}[/tex]

yes it's on a 1.5 scale factor.....I think. The question you put at the top threw me off at first but the picture makes sense. I'm not entirely sure if this is right but if you adjust the triangle to be the same way as the other one then you will see which sides correspond to each other. Each number can be multiplied by 1.5 to get the number that is on the side of the other triangle that corresponds with it....if that makes any sense

Answers
angle 2=42

The measures of unknown angles are, m∠2 is 42°, m∠1 = 88° and
m∠3 = 113°.
What is a transversal?We know when a transversal intersects two parallel lines at two distinct points,
Two pairs of interior and alternate angles are formed such that the measure of interior angles are same and the measure of alternate angles is also the same.
We know vertically opposite angles are of equal measure.
∴ m∠2 is 42°.
We know the sum of all the interior angles in a triangle is 180°.
∴ m∠1 = 180° - 50° - 42°.
m∠1 = 88°.
m∠3 = 180° - 42° - 25°.
m∠3 = 113°.
