Step 1: Let T be Tien's age and J as Jordan's age (today),
[tex]T=\frac{1}{4}J[/tex]
Step 2: Let T be Tien's age and J as Jordan's age (in 2 years),
[tex]T+2=\frac{1}{3} (J+2)[/tex]
[tex]T=\frac{1}{3}(J+2)-2[/tex]
Step 3: As their age differences will always be similar we can have the two equations above equal to find Jordan's age,
[tex]\frac{1}{4} J=\frac{1}{3}(J+2)-2\\\frac{1}{4}J-\frac{1}{3}J=\frac{2}{3} -2 \\-\frac{1}{12}J= -\frac{4}{3} \\\\J=16[/tex]

Find the surface area of the rectangular prism.
Answers
Answer:
SA = 112
Step-by-step explanation:
A = 2wl + 2lh + 2hw
length = 8 km
width = 2 km
height = 4 km
SA = 112 km
112
Step-by-step explanation:
SA = 2lh + 2lw + 2hw
where l = length w = width and h = height
Dimensions: l = 8, w = 2 and h = 4.
SA = 2(8)(4) + 2(8)(2) + 2(4)(2)
SA = 2(32) + 2(16) + 2(8)
SA = 64 + 32 + 16
SA = 112 km
The surface area of the rectangular prism is 112 km.

An average woman walks at a speed
of 255 feet per minute. At this rate,
how far would Mrs.
ft
Hill walk in an hour?
Answers
Answer:
15,300 ft or 2.9 miles
Step-by-step explanation:
Distance = Rate * Time (but rate and time must be in the same units)
convert hours to minutes
1 hr * 60 min/hr = 60 min
then
D = 255 ft/min * 60 min
D = 15,300 ft
if you want miles, convert ft to miles (5280 ft per mile)
15,300 ft * 1 mi/5280 ft
2.9 mi
A candy jar contains several small pieces of candy:
• 5 miniature peanut butter cups
• 7 dark chocolate candy bars
• 8 gummy worms
Roger randomly selected one piece of candy from the jar.
Problem
Read aloude What is the probability in decimal form that the candy Roger selected was NOT a gummy worm?
Answers
Answer:
12/20 = 60%
Step-by-step explanation:
The probability that the candy Roger selected was NOT a gummy worm;
P(Not a gummy worm) = 0.6
We are told the quantity of candies in the jar is as follows;
Miniature peanut butter cups = 5
Dark Chocolate bars = 7
Gummy worms = 8
Total number of candy bars = 5 + 7 + 8
Total number of candy bars = 20
Probability is found as; number of possible outcomes/number of events.
P(randomly selected is a gummy worm) = 8/20
P(randomly selected is a gummy worm) = 0.4
Thus, probability that it was not a gummy worm = 1 - 0.4Probability that it was not a gummy worm = 0.6

Does the point (-9,-4) satisfy the equation y = x + 5?
Answers
Answer:
Yes it satisfies the equation
Step-by-step explanation:
Let, P(x,y) = (-9,-4)
Then, x = -9
y = -4
if we use this value in the equation, we will get L.S = R.S ;(-4 = -9 + 5)
So, the point satisfies the equation

Solve d−85=p for d .
Answers
Answer:
d = p + 85
Step-by-step explanation:
We don't have a lot to go on for this problem. We have two undefined variables.
In order to solve for d, we need to isolate it:
d - 85 = p
Add 85 to both sides
d = p + 85

Answers
Answer:
2.25 km to go
Step-by-step explanation:
In order to get this answer, you have to figure out how many km 10% is, 0.1125. Then multiply that by the remaining 20% because he already finished 80% of the trail. So, 0.1125 x 20 = 2.25.

A student is assessing the correlation between the number of hours a plant receives sunlight and the height to which it grows. The table shows the data:

Height of plant in cm
(y) 4 7 10 13 16 19 22 25 28 31
Part A: Is there any correlation between the number of hours of sunlight that a plant receives and the height to which it grows? Justify your answer. (4 points)
Part B: Write a function that best fits the data. (3 points)
Part C: What does the slope and y-intercept of the plot indicate about the plant? (3 points)
Answers
Answer:
Hello,
Step-by-step explanation:
Part A:
Yes
Since
y=f(x)
f(0)=4
f(1)=7 : f(1)=f(0)+1*3
f(2)=10= 7+3 : f(2)=f(1)+3 =f(0)+2*3
f(3)=13=10+3: f(3)=f(2)+3=f(0)+3*3
...
f(9)=31=28+3=f(8)+3=f(0)+9*3
f(n)=f(0)+n*3=4+n*3
Part B: y=3x+4
Part C: slope=3 , y-intercept=4
The slope indicate the grow of the plant (how many cm does it grow in function of the height it receives)
y-intercept indicate the original height of the plant.
The HCF of 85 and 95
Answers
Answer:
So the greatest common factor 85 and 95 is 5.
Step-by-step explanation:
We will now calculate the prime factors of 85 and 95, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 85 and 95.
We will first find the prime factorization of 85 and 95. After we will calculate the factors of 85 and 95 and find the biggest common factor number .
Step-1: Prime Factorization of 85Prime factors of 85 are 5, 17. Prime factorization of 85 in exponential form is:
85 = 5^1 × 17^1
Step-2: Prime Factorization of 95Prime factors of 95 are 5, 19. Prime factorization of 95 in exponential form is:
95 = 5^1 × 19^1
Step-3: Factors of 85List of positive integer factors of 85 that divides 85 without a remainder.
1, 5, 17
Final Step: Biggest Common Factor NumberWe found the factors and prime factorization of 85 and 95. The biggest common factor number is the GCF number.
So the greatest common factor 85 and 95 is 5.

Solve the equation using the zero-product property.
(x-8)(5x-6)=0
A. x = 8 or x = -1 1/5
B. x = –8 or x = 1 1/5
C. x = –1 or x = 5
D. x = 8 or x = 1 1/5
Answers
Answer:
D. x = 8 or x = 1 1/5
Step-by-step explanation:
x = 8 6/5
x = 8 1/5
zero-product property says to equate each factors to 0 .
so the factors in (x − 8)(5x − 6) = 0
are (x-8) and (5x-6)
hence equating them to 0
x-8 =0 or 5x-6 =0
x=8 or 5x=6
x=8 or x=6/5
x=8 or x= 1 and 1/5

Show that the two angles are congruent at 65 each
Tangents touch the circle and make a right angle with the radii.
The radii are equal Property of radii.
The center line is common to both triangles. Reflexive line
The tangent lines are congruent Found from Pythagoras
The triangles are congruent SSS
The two angles are congruent Parts of Congruent Δs
Add the 2 congruent angles of 65 each.

The entire circle has 360 degrees.
Subtract 130 from 360
