Answer:
44° and 99°
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Subtract the 2 given angles from 360° to find the remaining sum
360° - (63 + 154)° = 360° - 217° = 143°
The 2 angles which sum to 143° are in the ratio 4 : 9
sum the parts of the ratio, 4 + 9 = 13 parts , then
143° ÷ 13 = 11° ← value of 1 part of the ratio, so
4 parts = 4 × 11° = 44°
9 parts = 9 × 11° = 99°
The other 2 angles are 44° and 99°
(ii) Kolyan has $9 to spend.
Work out the total amount Kolyan spends on water and biscuits as a fraction of the $9.
Give your answer in its lowest terms.
The amount spent on water and biscuits is $5.4 and $3.6, respectively
From the question, the ratio is given as:
[tex]Biscuits : Water= 3 : 2[/tex]
Represent both proportion as a fraction
[tex]Biscuits = \frac 35[/tex]
[tex]Water= \frac 25[/tex]
Kolyhan has $9.
So, the amount spent on biscuit is:
[tex]Biscuit= \frac 25 \times 9[/tex]
[tex]Biscuit= 3.6[/tex]
The amount spent on water is:
[tex]Water = 9 - 3.6[/tex]
[tex]Water = 5.4[/tex]
Hence, the amount spent on water and biscuits is $5.4 and $3.6, respectively

Your little brother wants hot chocolate ot be 150 degrees, but you accidentally heated the water to 175 degrees. If after 5 minutes the temperature is 165 and the temperature in your house is 70 degrees, how long will your little brother have to wait to drink his hot chocolate?
Answer:
12.5 minutes
Step-by-step explanation:
it takes 5 minutes to cool 10 degrees
after ten minutes it would be 20 degrees less
then after 2.5 minutes it would be 5 degrees less
so it would take you 12.5 minutes to get 25 degrees less
We know that in 5 minutes, the temperature of the hot chocolate decreased by 10 degrees. We also know that the temperature is fixed at 70 degrees. Now, using the info given, let's solve!
=> 5 minutes = 10 degrees decrease=> 1 minute = 2 degrees decrease=> 1 minute x 12.5 = 2 x 12.5 degrees decrease=> 12.5 minutes = 25 degrees decreaseConclusion:Therefore, my little brother will have to wait for 12.5 minutes to drink his hot chocolate.

Answer
If we had a sale price of 30% off of $1,050then the sale price is 70% of $1,050 or 0.7(1050) Then we add 7% sales tax to that making thefinal price paid 107% of [0.7(1050)] ... 1.07[0.7(1050)] = $786.45

The sum of twice a number and 5 is 25
Answer:
If the directions say write an equation: 2n + 5 =25
If the directions say also to solve the equation and find the number: 10
Step-by-step explanation:
"The sum" means we're using adding. So what things are we adding together? The question says "twice a number" and 5. Well we've got the 5. And "twice" means two times. And "a number" means we don't know the number yet, so we choose a variable, like n.
"Twice a number" can be written 2n.
So far we have:
2n + 5 is 25
We use = for the "is" in this sentence.
2n + 5 = 25
Now we can solve it.
Subtract 5 from both sides.
2n = 20
Divide by 2 on both sides.
2n/2 = 20/2
n = 10
The number is 10.

A system of equations is shown: 2x = â’y 6 â’4x 3y = 8 What is the solution to this system of equations? (â’1, â’4) (1, 4) (4, 1) (â’4, â’1).
The correct option is B. (1,4).
Given equations,
[tex]2x=-y+6....(1)\\-4x+3y=8....(2)[/tex]
We have to find the solution of the given system of equations.
Equation 2 can be written as,
[tex]-2\times(2x)+3y=8\\[/tex]
Now by substitution method, putting the value of [tex]2x[/tex] from Equation (1) in above equation, we get
[tex]-2\times(-y+6)+3y=8\\2y-12+3y=8\\5y-12=8\\5y=20\\y=4[/tex]
Now putting the value of y in equation 1 we get,
[tex]2x=-4+6\\2x=2\\x=1[/tex]
Hence the solution of the given system of equation will be (1,4).
