If the larger triangle has a perimeter of 62 feet, its area will be 120 square feet.
We know that the perimeter of the smaller triangle is 31 feet, which means that the sum of the lengths of its three sides is 31 feet. We also know that the area of the smaller triangle is 40 square feet. We can set up the following equation to calculate the length of each side of the smaller triangle:
Side 1 + Side 2 + Side 3 = 31
We can then use the formula for the area of a triangle, A = bh/2, to calculate the length of the base and height of the smaller triangle. Since we know the area is 40 square feet, we can set up the following equation:
40 = (b)(h)/2
We can then solve this equation for b and h. We know that b + h = 31, so we can set up the following equation and solve for h:
h = 31 - b
Now that we know b and h for the smaller triangle, we can use the same formula to calculate the area of the larger triangle. Since we know that the perimeter of the larger triangle is 62 feet, we can set up the following equation to calculate the length of each side of the larger triangle:
Side 1 + Side 2 + Side 3 = 62
We can then use the following formula to calculate the area of the larger triangle:
A = (b)(h)/2
We know that b + h = 62, so we can set up the following equation and solve for h:
h = 62 - b
Now that we know b and h for the larger triangle, we can plug those values into the area formula and calculate the area of the larger triangle. The area of the larger triangle is 120 square feet. Therefore, if the larger triangle has a perimeter of 62 feet, its area will be 120 square feet.

Jeremy's mother deposited $1,200 into a
savings account as a college fund when he
was born. How much will Jeremy have in
this account after 18 years at a yearly
simple interest rate of 4.25%?
A) $51.00
C) $918.00
B) $10,380.00
D) $2,118.00
Answer: D) $2,118.00
Step-by-step explanation:
1 year = 4.25% interest rate
18 years = 76.5% interest rate
76.5% = 0.765
Take 1200 times 0.765 = $918.00
$918.00 is the interest money he will receive after 18 years. We have to add both numbers to find the total.
$1,200 + $918.00 = $2118.00
The length and width of a rectangle are consecutive integers. The area of the rectangle is 156 square feet. Find the length and width of the rectangle.
Answer:
L = 12ft
W = 13ft
Step-by-step explanation:
Let's use the two pieces of information to make 2 equations (we need 2 eqns to solve for 2 variables: Length and Width).
The length and width are consecutive integers
L+1=W
The area of the rectangle is 156 square feet.
L*W=156
We know that W=L+1 from our first equation, so substituting that information into our second equation we get
L*(L+1)=156
Let's distribute that L
L^2 + L = 156
and subtract 156 from both sides
L^2 + L - 156 = 0
Now we can use the quadratic formula to find L. L cannot be negative, so
L = 12
using our very first equation we know L, so we can solve for W.
L+1=W
12+1=W
W = 13
One week, 100 tudent purchaed item from the tudent tore and the tore made a profit of $500. The next week, when 80 tudent purchaed item, the profit wa $460. Write a linear equation relating profit, to the number of tudent,
A linear equation relating profit, to the number of student is shown below.
y = 2x + 500
Linear equation is used to present the elements in mathematic. A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept. Occasionally, the above is called a "linear equation of two variables," where y and x are the variables.
To write a linear equation relating profit to the number of students, we need to find the slope and the y-intercept of the line.
The slope of the line can be calculated using the formula:
slope = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
In this case, we can use the two data points given to find the slope:
slope = (460 - 500) / (80 - 100) = -40/ -20 = 2
The y-intercept of the line is the point where the line crosses the y-axis, which is the profit when the number of students is 0. In this case, the y-intercept is 500, since that is the profit when 100 students purchase items.
Using these values, we can write the linear equation in slope-intercept form:
y = 2x + 500
This equation can be interpreted as follows: the profit (y) is equal to 2 times the number of students (x) plus 500.

Paing through (3, 4) and perpendicular to the line whoe equation i y=1/9x8; lope-intercept form
The equation of the line passing through (3, 4) and perpendicular to the line y=1/9x + 8 in slope-intercept form is y = -9x + 31
Suppose we have two lines with slope m₁ and m₂ respectively, then those lines are perpendicular to each other if
m₁ x m₂ = -1
In the given problem, the line is perpendicular to a line whose equation is:
y = 1/9 x + 8
Hence,
m₁ x m₂ = -1
1/9 x m₂ = -1
m₂ = -9
Therefore, the equation of the second line is:
y = -9x + b
To find the value of b, we use the fact that the line passing through (3,4)
Substitute x = 3, and y = 4
4 = -9 (3) + b
b = 4 + 27 = 31
Thus, the equation of the line is:

Ticket to a baketball game can be ordered online for a et price per ticket plu a $5. 50 ervice fee. The total cot in dollar for ordering 5 ticket i $108. 0. Which linear function repreent c, the total cot, when x ticket are ordered? (A ervice fee i a ingle fee applied to the total, no matter the number of ticket purchaed). C(x) = 5. 50 20. 50x
c(x) = 5. 50x 20. 50
c(x) = 5. 50 21. 60x
c(x) = 5. 50x 21. 60
The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.
The total cost for ordering 5 tickets is $108.00. This means that each ticket costs $20.50 plus a service fee of $5.50.
Therefore, we can create a linear function that represents the total cost when x tickets are ordered. The function is: c(x) = 5.50 + 21.60x. This means that for each ticket purchased, an additional $21.60 will be added to the service fee of $5.50.
When x = 5, then c(x) = 5.50 + 21.60x = 5.50 + 21.60(5) = 108.00, which matches the given total cost.

You're at a clothing tore that dye your clothe while you wait. You get to pick from 444 piece of clothing (hirt, pant, ock, or hat) and 333 color (purple, blue, or orange). If you randomly pick the piece of clothing and the color, what i the probability that you'll end up with an orange hat?
We will discover that the probability that you will at random wind up with an orange hat is as follows: P = 1/12
Observe how we arrived at that now:
4 pieces of clothing (shirt, pants, socks, or hat)
three hues (purple, blue, or orange)
The color of only one item of clothing will change. The likelihood that you will receive an orange hat is what we are looking for.
We must first determine the likelihood that you will choose a hat at random. The likelihood of picking your hat at random is if all the apparel has the same probability of being chosen, just one more than the number of options (4). p = 1/4
The color is now chosen at random using the same methodology as before, with the likelihood that orange will be chosen at random being: q = 1/3.
When we multiply the individual probabilities by the joint probability, we obtain:
P = q*p = (1/4)*(1/3) = 1/12

Step-by-step explanation:
For a set of data to have a median that is greater than the mean, it must have an odd number of values and be skewed to the right. This means that the majority of the values in the set must be smaller than the median, with a few larger values on the right side of the distribution.
Out of the given options, the only set of data that satisfies these conditions is (B) {8, 12, 14, 14, 22}. This set has an odd number of values, and the median of 14 is greater than the mean of 14.4. The other options have either an even number of values, or are not skewed to the right.

sketch the curve with equation x2/3 + y2/3 = 4 and use symmetry to find its length.
The equation x²/3 + y²/3 = 4 represents an ellipse in the shown graph below and the length of the given ellipse is 8 units.
The equation x²/3 + y²/3 = 4 represents an ellipse centered at the origin with a major axis along the x-axis and a minor axis along the y-axis.
The equation can be rewritten as x²/4 + y²/12 = 1 to highlight the lengths of the semi-major and semi-minor axes.
The semi-major axis length is given by the square root of the denominator of the x-term, which is 4, so the semi-major axis length is 2.
The semi-minor axis length is given by the square root of the denominator of the y-term, which is 12, so the semi-minor axis length is 2√3.
Based on the symmetry of the ellipse, we can determine that it is symmetric with respect to both the x-axis and the y-axis.
This means that the length of the entire ellipse can be found by multiplying the semi-major axis length by 4, since there are 4 identical sections due to symmetry.
Length of the ellipse = 4 * semi-major axis length
= 4 * 2
= 8.
Therefore, the length of the given ellipse is 8 units.

Lee i packing a truck with mall and large filing cabinet. The large cabinet weigh 30 pound, and the mall cabinet weight 20 pound. To optimize the load, the total load weight hould be 1550 pound from a total of 65 cabinet. How many of each ize of cabinet hould Lee pack in the truck?
The number of cabinets of large size Lee should pack is equal to 40 and that of small size is equal to 25.
To determine how many of each size of cabinet Lee should pack in the truck, you can set up a system of equations. Let X be the number of large cabinets and Y be the number of small cabinets.
The total weight of the large cabinets is 30X pounds, and the total weight of the small cabinets is 20Y pounds. The total weight of all the cabinets is 1550 pounds, so the equation to represent this is:
30X + 20Y = 1550
The total number of cabinets is the sum of the number of large cabinets and the number of small cabinets, so the equation to represent this is:
X + Y = 65
To solve this system of equations, you can use the substitution method. First, solve for X in the second equation by substituting 65 - Y for X:
X = 65 - Y
Then, substitute 65 - Y for X in the first equation:
30(65 - Y) + 20Y = 1550
Solving this equation for Y, you get:
Y = 25
Substituting this value for Y in the second equation, you get:
X = 65 - 25 = 40
So, Lee should pack 40 large cabinets and 25 small cabinets in the truck.
