The number of months is 10 months using the given equation, So the tree was planted before 10 months.
Linear equation-based problem:What information do we have?
y = 12x + 60
y, the height of a tree in centimeters = 150 cm tall
x months after it is planted
Using linear equation
y = 12x + 60
150 = 12x + 60
12x = 150 - 60
12x = 120
x = 10
Number of month = 10 months

The cost of 5 dresses and 2 belts is $48. The cost of 3 dresses and 2 belts is $32. Find the cost of a dress and a belt. Let x denote the cost of a dress and y denote the cost of a belt.
A: x = $8, y = $4
B: x = $5, y = $4
C: x = $7, y = $10
D: x = $4, y = $5
Step-by-step explanation:
• 5X + 2Y = 48
• 2Y = 48 - 5X
let's use this and replace it on the second equation
• 3X + 2Y = 32
• 3X + 48 - 5X = 32
• 3X - 5X = 32 - 48
• -2X = -16
• X = 8
now use the X value we found to find the Y
• 5X + 2Y = 48
• 5*8 + 2Y = 48
• 40 + 2Y = 48
• 2Y = 48-40
• Y = 8/2
• Y = 4
A: x = $8, y = $4

what's the slope of (-3,3) and (-1,2)
Answer:
Step-by-step explanation:
Slope is defined as
m=(y2-y1)/(x2-x1)
We are given two (x,y) points of (-3,3) and (-1,2) so
m=(3-2)/(-3- -1)
m=1/-2
m=-1/2
3. Nutrition labels. The nutrition label on a bag of potato chips says that a one ounce (28 gram) serving of potato chips has 130 calories and contains ten grams of fat, with three grams of saturated fat. A random sample of 35 bags yielded a sample mean of 134 calories with a standard deviation of 17 calories. a. Calculate the 95% confidence interval of for this random sample. Then interpret this interval.
Answer:
The 95% confidence interval of for this random sample is between 128.16 calories and 139.84 calories. This means that we are 95% that the mean number of calories for all bags of potato chips is in this interval.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 35 - 1 = 34
95% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 34 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 2.0322
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 2.0322\frac{17}{\sqrt{35}} = 5.84[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 134 - 5.84 = 128.16 calories
The upper end of the interval is the sample mean added to M. So it is 134 + 5.84 = 139.84 calories
The 95% confidence interval of for this random sample is between 128.16 calories and 139.84 calories. This means that we are 95% that the mean number of calories for all bags of potato chips is in this interval.

Find the surface area of the prism. centimeters 7 17 8 15
Answer:
400 cm²
Step-by-step explanation:
1/2x2x15x8=120
17x7=119
7x8=56
15x7=105
120+119+56+105=400
The total surface area of a given prism is 400 cm².
What the surface area of a prism?To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.
The total surface area of a Prism = (2 × Base Area) + (Base perimeter × Length).
Here, Base area = 1/2 ×Base×Height
= 0.5×8×15
= 60 cm²
Base perimeter = 15+8+17
= 40 cm
Now, total surface area = 2×60+(40×7)
= 120+280
= 400 cm²
Therefore, the total surface area of a given prism is 400 cm².

In rectangle SORE below, m∠REO = (x + 50)° and m∠SEO = (3x - 20)°, what is the measure of m∠RSE?
Answer:
65degrees
Step-by-step explanation:
In rectangle SORE below, m∠REO = (x + 50)° and m∠SEO = (3x - 20)°, what is the measure of m∠RSE?
From the rectangle SORE, m<SEO + m<RSE = 90
Substitute the given angles
x+50+3x-20 = 90
4x + 30 = 90
4x = 90-30
4x = 60
x = 60/4
x = 15
Get m<RSE
mRSE = m<REO = x+50
m<RSE = 15+50 = 65degrees

The circle graph shows how the annual budget for a company is divided by department. If the amount budgeted for Media and Engineering
combined is $12,500,000, what is the total annual budget?
Answer:
The total annual budget of the company is $ 50,000,000,000.
Step-by-step explanation:
Given that the circle graph shows how the annual budget for a company is divided by department if the amount budgeted for Media and Engineering combined is $ 12,500,000, to determine what is the total annual budget of the company the following calculation must be performed:
Media + Engineering = 25%
12,500,000 / 25 = 500,000
500,000 x 100 = X
50,000,000,000 = X
Thus, the total annual budget of the company is $ 50,000,000,000.

1. The length of a rectangle is 1 less than 4 times the width. If the perimeter is 118 ft., find
the length and the width. You must solve algebraically.
2. Ally scored 5 more than 7 times as many points as Gaelle during the weekend
basketball game. If they scored 45 points, how many did Ally score?
You must solve algebraically.
Answer:
Step-by-step explanation:
1.
L=4W-1
P=2(L+W)=118, using L from above makes this
2(4W-1+W)=118,
2(5W-1)=118
5W-1=59
5W=60
W=12, and since L=4W-1
L=4(12)-1
L=47
So the length is 47ft and the width is 12ft
2.
A=7G+5
7G=A-5
G=(A-5)/7, and we are told A+G=45, using G=(A-5)/7 gives us
A+(A-5)/7=45
(7A+A-5)/7=45
(8A-5)/7=45
8A-5=315
8A=320
A=40

Agnete consumes 1.68 grams of caffeine in a week.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
We know that Agnete drinks 3 cups of drip coffee every day, and each cup contains 8 oz of coffee, which is equivalent to 80 mg of caffeine.
To find out how many grams of caffeine Agnete consumes in a week, we can start by calculating the total amount of caffeine she consumes in a day:
Total caffeine in a day.
= 3 cups x 80 mg/cup
= 240 mg
Then, we can multiply this value by 7 to find the total amount of caffeine she consumes in a week:
Total caffeine in a week = 240 mg/day x 7 days/week = 1680 mg
To convert milligrams (mg) to grams (g), we divide by 1000:
Total caffeine in a week = 1680 mg / 1000 = 1.68 g
Therefore,
Agnete consumes 1.68 grams of caffeine in a week.
