Suppose 28 members of your class went on a rafting trip. Class members could either rent canoes for S16 each or rent kayaks for $19 cach. The class spent a total $469. How many people rented canoes and how many people rented kayaks?
Answer:
kayaks = 7
Canoes = 21
Step-by-step explanation:
Answer:
canoes = 21
kayaks = 7
Step-by-step explanation:
x = students rent canoe
y = students rent kayak
x + y = 28
16x + 19y = 469
elimination of x (times the 1st equation by 6)
16x + 16y = 448
16x + 19y = 469
---------------------- –
-3y = -21
y = -21/-3 = 7 people
subtitute y to find x
x + y = 28
x + 7 = 28
x = 28 - 7 = 21 people

what is perpendicular to 3x+4y+12=0?
Answer:
y=4/3x-3
Step-by-step explanation:
We can rearrange the equation for y-intercept form:
3x+4y+12=0
4y=-3x-12
y=-3/4x-3
The perpendicular equation would have an inverse slope, so we flip -3/4
y = 4/3x -3
Solve for X. 3/4x+7/8=4 1/4 Enter your answer as a mixed number in simplest form in the box.
Step-by-step explanation:

[tex]24x = 108[/tex]
[tex]x = \frac{108}{24} [/tex]
[tex]x = \frac{9}{2} [/tex]
The value of x in the expression (3/4)x+7/8 = 17/4 is 9/2.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, (3/4)x+7/8 = 17/4.
Now to get rid of the denominator LCM of 4 and 8 is 8 so we'll multiply each term by 8.
6x + 7 = 34.
6x = 27.
2x = 9.
x = 9/2.

5. Tristan wants to build a square garden in
his backyard. If the garden is going to be 64
ft2, how many feet of material will he need for
the perimeter of the garden?
Answer:
The perimeter of the garden is 32 feet
Step-by-step explanation:
The shape of the garden is a square
A square is a quadrilateral with equal sides.
Perimeter of a square = 4 x length
In order to determine the perimeter, the length of the side of the garden has to be determined.
Area of a square = length²
64 = length²
length = √64
length = 8 feet
Perimeter = 4 x 8 = 32 feet
which distance is longer 500 kilometers or 250 miles explain
The measurement of 500 km is greater than 250 miles
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
To compare the distances, we need to convert one of them to the same unit as the other. One kilometer is approximately equal to 0.621 miles, so we can convert 500 kilometers to miles:
From the unit conversion , we get
1 km = 0.621 miles
500 kilometers = 500 x 0.621 = 310.68 miles (rounded to two decimal places)
Now we can compare distances 310.68 miles to 250 miles. Since 310.68 miles is greater than 250 miles, we can conclude that 500 kilometers is a longer distance than 250 miles.

Dennis wants an average of 90 or higher in math class. Currently he
has grades of 87,93,78,100 and 95, what must he make on his next
assignment to achieve his goal?
Answer:
With the listed scores, he already has an average of 90.6 He needs to score a minimum of 87 to keep an average of 90.
The marks Dennis should get in his assignment to achieve his goal is 87.
Given that, Dennis wants an average of 90 or higher in math class.
What is the average?In maths, the average value in a set of numbers is the middle value, calculated by dividing the total of all the values by the number of values. When we need to find the average of a set of data, we add up all the values and then divide this total by the number of values.
Let the marks in the next assignment be x.
Now, average = Sum of all the observations/Total number of observations
(87+93+78+100+95+x)/6 = 90
⇒ (453+x)/6 =90
⇒ 453+x = 540
⇒ x=540-453
⇒ x=87
Therefore, the marks Dennis should get in his assignment to achieve his goal is 87.
