Answer:
Addison worked 5 hours
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y = kx
Where k is the constant of proportionality.
The relationship between the number of kilograms of dough Addison prepares (y) is proportional to the number of hours he works on it (x).
Knowing he prepared y=30 kilograms of dough after t=3 hours, we substitute in the function:
30 = 3k
Solving for k:
k = 30/3 = 10
The relationship is:
y = 10x
If he prepared y=50 kg of dough, then:
50 = 10x
Solving for x
x = 50/10 = 5
Addison worked 5 hours

A plane flying at an altitude of 4 miles is approaching an airport that is 31 miles ahead on
the pilot's line of sight. What is the angle of depression from the plane to the airport to the
nearest TENTH of a degree?
Answer:
[tex]7.4^{o}[/tex]
Step-by-step explanation:
Altitude of the plane = 4 miles
Distance from the plane to the airport = 31 miles
Let the angle of depression from the plane to the airport be represented by θ. Thus applying the appropriate trigonometric function, we have;
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
= [tex]\frac{4}{31}[/tex]
= 0.1290
θ = [tex]Tan^{-1}[/tex] 0.1290
= 7.3506
θ = [tex]7.4^{o}[/tex]
The angle of depression from the plane to the airport is [tex]7.4^{o}[/tex].

Buddy and his Step-brother Michael are in a snowball fight! They get hit by 85% of the snowballs.
If there were 200 snowballs thrown, how many were they hit by?
Answer: 170
Step-by-step explanation:
Since they get hit by 85% of the snowballs and there were 200 snowballs thrown, the number of snowballs that hit them will be gotten by multiplying 85% by 200. This will be:
= 85% × 200
= 0.85 × 200
= 170
Therefore, 170 snowballs hit them

Find the sum of the first 6 terms of the infinite series: 1 – 2 + 4 – 8 + . . .
Answer:
The sum of the first 6 terms of the inifinite series is -21.
Step-by-step explanation:
Following the sequence, we can see that each term is the previous term multiplied by -2. So, the first six terms are:
1, -2, 4, -8, 16, -32
The sum is:
1 - 2 + 4 - 8 + 16 - 32 = -1 - 4 - 16 = -21
The sum of the first 6 terms of the inifinite series is -21.
Answer:
-21

Estimate the average rate of change from x = 3 to x = 7.
Answer:
Average rate of change = 1.333 or 133.33%
Step-by-step explanation:
Given:
Base x = 3
New x = 7
Find:
Average rate of change
Computation:
Average rate of change = [new - base]/base
Average rate of change = [7 - 3] / 3
Average rate of change = 1.333 or 133.33%

11) In a triangle, the ratio of the measures of three angles is 2:5:8. Find the measures of
each angle in the triangle. Show proportions.
Answer:
Sum of interior angles of a triangle always = 180 degrees
add the individual ratios to get a sum composite ratio:
2+5+8 = 15
180 / 15 = 12
Multiply individual ratios:
{2:5:8} * 12 = 24:60:96
Check:
24 + 60 + 96 = 180

Solve the system of equations.
Answer:
x =-5 and y = -6
Step-by-step explanation:
In order to get the answer, I used the elimination/addition method
8y-9x= -3 <— I decided to eliminate the y
5y-8x= 10 <— I decided to eliminate the y
5(8y-9x = -3) <— switch up the number of y from the bottom to multiply
-8(5y-8x= 10) <— switch up the number of y from the top to multiply, but have a negative sign to it
So...our new equation will be....
40y - 45x = -15
+ -40y + 64x = -80
________________________
19x = -95
x = -5
8y-9x= -3
8y-9(-5) = -3
8y+45 = -3
- 45 = - 45
8y = -48
y = -6

Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded
monthly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $12,110?
Answer:
17
Step-by-step explanation:
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. It takes 17 year for the value of the account to reach $12,110.
What is Compound interest?Compound interest is a method of calculating the interest charge. In other words, it is the addition of interest on interest.
Compound Interest =P(1+r/n)^rt
Adrian invested $7,200 in an account paying an interest rate of 3.1% compounded monthly. for the value of the account to reach $12,110 we need to find the time it takes.
The principal amount = $7,200
Rate = 3.1%
Compound Interest = [tex]P(1+r/n)^{rt}[/tex]
12,110 = [tex]7200(1+3.1/12)^{3.1t}[/tex]
t = 17
Thus, for the value of the account to reach $12,110 the time taken is 17.

n^2 + 16n+63 (factor)
Step-by-step explanation: This trinomial is in a special form
that can be factored into the product of two binomials.
So setup 2 sets of parenthses.
The first term in each set is a factor of n²
and since n factors as n times n, we use an n.
For the second term, use factors of the last term that
add to the coefficient of the middle term.
The factors of 63 that add to 16 are 9 and 7.
So we have (n + 9)(n + 7) which is our answer.

A polygon is transformed according to the rule: (x, y)-(x + 2, y). Every point of the polygon moves two units in which direction?
Answer:
Every point of the polygon moves horizontal translation right '2' units
Step-by-step explanation:
Explanation:-
Type of transformation Change of co-ordinate point
Vertical transformation
up 'd' units (x, y ) → ( x , y +d)
Vertical transformation
down 'd' units (x, y ) → ( x , y -d)
Horizontal transformation
left 'c' units (x, y ) → ( x-c , y )
Horizontal transformation
right 'c' units (x, y ) → ( x+C , y )
Given that a polygon is transformed according to the rule: (x, y)-(x + 2, y)
∴ Every point of the polygon moves horizontal translation right '2' units

If the standard deviation of shear strength measurements for spot welds is 9.5 pounds per square inch (psi), what is the minimum number of test welds that should be sampled if we want the sample mean to be within 1.4 psi of the true mean with probability approximately 0.99
Answer: 306
Step-by-step explanation:
Formula to find sample size:
[tex]n=(\dfrac{\sigma\times z^*}{E})^2[/tex] , where [tex]\sigma[/tex] = standard deviation, E = margin of error, z* = critrical z-value.
As per given,
[tex]\sigma=9.5 , E=1.4[/tex]
Critical z-value for 99% confidence = 2.576
Now , the minimum sampl size :[tex]n=(\dfrac{9.5\times2.576}{1.4})^2[/tex]
[tex]\Rightarrow\ n=305.5504\approx306[/tex]
Hence, the required sample size = 306
