Four friends were born in consecutive years. The sum of their
ages is 94. What is the age of the oldest friend?
Answer:
25
Step-by-step explanation:
Since they were born on consecutive years, their ages are 4 consecutive whole numbers. Let the lowest age be x. Then the other ages are x + 1, x + 2, and x + 3.
Now we add the 4 expressions and set the sum equal to 94.
x + x + 1 + x + 2 + x + 3 = 94
4x + 6 = 94
4x = 88
x = 22
The youngest one is 22.
The oldest one is
x + 3 = 22 + 3 = 25
Answer: 25

The inverse, f'(x), of f(x) =
X + 5
Х
can be written as
5
x-1
a) Find f(2)
b) Find f'(2)
Step-by-step explanation:
Given
[tex]f(x) = \frac{x + 5}{x} [/tex]
So
[tex]f(2) = \frac{2 + 5}{2} \\ = \frac{7}{2} [/tex]
Now
[tex] {f}^{ - 1} (x) = \frac{5}{x - 1} [/tex]
So
[tex] {f}^{ - 1} (2) = \frac{5}{2 - 1} \\ = \frac{5}{ 1} \\ = 5[/tex]
Hope it will help :)❤

the length of a boat is 10.8 m Boris buys a scale model of the boat the scale of the model is 1 to 18 work out the length of the scale model of the boat give your answer in centimetres
Answer:
The size of the scale model is 60 centimeters.
Step-by-step explanation:
Given that the length of a boat is 10.8 m, and Boris buys a scale model of the boat whose ratio is 1 to 18, to determine the length of the scale model of the boat in centimeters the following calculation must be performed:
1m = 100cm
10.8 m = (10.8 x 100) = 1080 cm
1080/18 = X
60 = X
Therefore, the size of the scale model is 60 centimeters.
You can text 44 words in 1 minute. Write a proportion to help you find
how many words you can type in 4 minutes. Which choice sets up the
proportion correctly and has the correct solution?
Answer:
176 words
Step-by-step explanation:
1) well we want to find the amount of words we'd be able to type in 4 minutes. so, what i did was:
44 words = x
1 minutes = 4 minutes
2) now look at how i set up the proportion, notice how i left a variable of x for the value i didn't know.
3) we also know that 1 times 4 is 4, so it'd also make sense to also multiply the numerator by 4 too!!
4) multiplying 44 by 4 would get us our answer which is 176

A triangle has sides of length 3 cm, 5 cm, and 7 cm.
Find the size of the largest angle in the triangle,
Answer:
C=120 degrees
Step-by-step explanation:
We can use the law of cosines to find an angle when we have all three sides
(7)^2 = (5)^2 + (3)^2 -(2)(5)(3)Cos(C)
49 = 25 +9 -30Cos(c)
49= 34 -30Cos(c)
15 = -30Cos(c)
Cos(c) = -1/2
C=120 degrees

What is ¨0.83% of n is 18.26¨ (just tell me the value of n)
Answer:
N = 2,200'Percent (%)' means 'out of one hundred':
0.83% = 0.83 'out of one hundred',
p% is read p 'percent',
0.83% = 0.83/100 = 0.83 ÷ 100
Calculate percentage:
'Percentage' is obtained by multiplying 2,200 by 0.83%
0.83% × 2,200 =
(0.83 ÷ 100) × 2,200 =
(0.83 × 2,200) ÷ 100 =
1,826 ÷ 100 =
18.26

Pls help me with my homework
Answer:
b = 8
Step-by-step explanation:
Using Pythagorean Theorem, a[tex]a^{2} +b^{2} =c^{2}[/tex], we just plug in what we know.
We know that the hypotenuse, c, is 10 km. We also know that one of the other side lengths is 6 km, we can plug that into either a or b.
Now, our equation will be: [tex]6^{2} +b^{2} =10^{2}[/tex].
You could also use the equation: [tex]b^{2} =10^{2} -6^{2}[/tex].
Next, we'll just solve the equation.
[tex]10^{2} =100[/tex], [tex]6^{2} = 36[/tex]
[tex]b^{2} =100 - 36[/tex]
[tex]b^{2} = 64[/tex]
[tex]\sqrt{b^{2} } = \sqrt{64}[/tex]
b = 8

Step-by-step explanation:
A line includes the points (-1,0) and (-2,-9). What is its equation in slope-intercept form?
Answer:
y = -7x -7
Step-by-step explanation:
If (-1, 0) and (-2, -9) are on the same line then that means their slope is the same. We can find slope with (y1 - y2)/(x1 - x2)
(-2 - (-9)) / (-1 - 0) = 7 / -1 = -7
then we can use the formula y = mx + b
we know that forthe first instance y = 0 and x = -1 and m(slope) = -7
0 = -7*-1 + b
0 = 7 + b
b = -7
our formula then becomes y = -7x -7
