The measures of the angles of a triangle are shown in the figure below. Solve for x.
Answer:
x = 57
Step-by-step explanation:
Angles of a triangle all add up to 180 so:
x + 78 + 45 = 180
x + 123 = 180
x = 180 - 123
x = 57

Step-by-step explanation:
the perimeter of a rectangle is 32cm, its length is more than its width by 2 what's the area
Answer:
63 cm^2
Step-by-step explanation:
p = l + w + l + w
32 = 2l + 2w
32 = 2(w + 2) + 2w
32 = 2w + 4 + 2w
32 = 4w + 4
28 = 4w
7 = w
l = w + 2
l = 7 + 2
l = 9
Check your work:
32 = 9 + 7 + 9 + 7
32 = 32
Correct
A = l × w
A = 9 × 7
A = 63

did u need to add water or take water away to get from the 4 cup mark to the 1 liter mark
Answer:
You have to add water.
Step-by-step explanation:
I hope this helps! Have a great rest of your day!
The decision to add water to meet the 4 cup mark of water would be:
Yes, the water must be added.
What is volume?"Volume" is described as the measure of a space that consists of length along with height and width.
Given that,
1 liter of water contains 1000 ml.
The capacity of a standard cup is 236.59 ml
If we take 4 cups, the total volume equals:
= 4 × 236.59
= 946.36 ml
Therefore, .23 cups or 53.64 ml of water would be required to be added.

4 A group of 40 mountain goats has just been
transplanted to an area with the expectation
their population will increase exponentially by
30% each year. If f(x) represents their total
population and x is the number of years in the
future, which function models the situation?
Answer:
f(x) = 40 × (1.3)ˣ
Step-by-step explanation:
4. The given parameters of the population of mountain goats are;
The initial number of mountain goats, a = 40
The rate at which their population will increase, r = 30% = 0.3 exponentially
The total population after 'x' years is given by f(x)
For exponential growth, we have;
f(x) = a·(1 + r)ˣ
Plugging in the values, we get;
f(x) = 40 × (1 + 0.3)ˣ = 40 × (1.3)ˣ

Theo practices yoga for the same amount of time every day. After he practices yoga for 18 min on Saturday, he has finished 24% of his daily yoga practice. How many more minutes does Theo practice yoga on Saturday? Show your work.
Answer:
Theo practices yoga on Saturday 57 more minutes.
Step-by-step explanation:
With the information provided, you can find the total amount of minutes Theo practices yoga that would represent 100% using a rule of three considering that you know that 24% of his daily yoga practice is equal to 18 minutes:
24% → 18
100% → x
x=(100*18)/24=75
As you need to find how many more minutes does Theo practice yoga on Saturday, you have to subtract 18 minutes that is the amount he has already spent practicing yoga from 75 that is the total amount of minutes he practices yoga:
75-18=57
According to this, Theo practices yoga on Saturday 57 more minutes.

Insert three rational and three irrationall
no. between 150 and
and 0
160
Answer:
Step-by-step explanation:
Rational numbers:
(150+160)/2 = 310/2 = 155
(150+155)/2 = 305/2= 152.5
(155 +160)/2 = 315/2= 157.5
155, 152.5 , 157.5 are rational numbers between 150 and 160
Irrational numbers:
Irrational numbers are numbers that are non terminating and non repeating numbers
155.502003000.....
155.202002000......
156.3120578.......
Answer:
Required Answer :-1st rational number
= a + b/2
= 150 + 160/2
= 310/2 (1)
2nd rational number
Middle term of 150 and 160 is 155
= 150 + 155/2
= 305/2
3rd rational number
= 160 + 155/2
= 315/2
