Answer:
d + r ≥ 30
$0.75d + $1.25r ≤ $30
Step-by-step explanation:
Given the following :
Number of items to purchase = atleast 30
Total cost must be no more than 30
cost of donut (d) = $0.75
Cost of cinnamon (r) = $1.25
Number of donuts and cinnamon to purchase
To total number of items :
Donut + cinnamon ≥ 30
d + r ≥ 30
Cost of items to purchase :
Cost = price per item * number of items
$0.75d + $1.25r ≤ $30
You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?
Answer:
$3
Step-by-step explanation:
Because you subtract $23-$11 to get the total you spent on avocados then you divide 12/4 because you bought 4 avocados
Answer:
3 dollars for each avocado.
Step-by-step explanation:
Since you had 23 dollars in the beginning and 11 dollars in the end, subtract to find out how much was used for the avacados.
23-11=12
Next, since you bought 4 avocados, you divide 12 by 4 to find out how much each cost.
12/4=3
Each avocado cost 3 dollars.
You can check by multiplying 3 by 4.
3x4=12
Then, add the 12 dollars spent to the 11 dollars left.
12+11=23 dollars

The length and width of a rectangle are in a ratio of 7:11. If the perimeter of the
rectangle is 72 cm. Find the
length and
width of the rectangle.
Answer:
14cm and 22cm
Step-by-step explanation:
Given parameters:
Perimeter of rectangle = 72cm
Ratio of length to width = 7: 11
Unknown:
Length and width of the rectangle = ?
Solution:
Since the ratio of length to width is 7: 11,
if the length is 7x , width = 11x
The perimeter of a rectangle can be obtained using
Perimeter = 2(L + W)
Insert the parameters and solve;
72 = 2(7x + 11x )
72 = 2(18x)
x = [tex]\frac{72}{36}[/tex] = 2
The length = 7x = 7x2 = 14cm
width = 11x = 11 x 2 = 22cm

H' = (-8/3, -10/3)
Step-by-step explanation:
how do you do this step by step
Answer:
x = 12
Step-by-step explanation:
30 degrees and 4x+2 are equal to 8+6x
First, write a formula or expression:
30 + 4x+2 = 8+6x
simplify this by collecting like terms
32 + 4x = 8+6x (minus 6x from both sides)
32 - 2x = 8 (minus 32 from both sides)
-2x = -24 (divide by -2)
x = 12
now sub into the formula:
30 + (4 × 12 +2) = 8 + 6 × 12
80 = 80

A zoo collected data on the diving times of turtles. Based on the data, the regression line is j = 0.010 + 2.515x, where x is the time of the dive, in minutes. Based on the regression equation, what is the predicted dive depth in meters at 150 seconds? Give your answer to three decimal places. meter(s)
Answer:
6.298 meters
Step-by-step explanation:
Here, we are told that x is the time of the dive in minutes.
We simply first need to convert 150 seconds to minutes before substitution into the regression formula;
Kindly recall that 60 seconds = 1 minute
So 150 seconds will be 150/60 = 2.5 minutes
We now proceed to substitute into;
j = 0.010 + 2.515(x)
i = 0.010 + 2.515(2.5)
j = 0.010 + 6.2875
j = 6.2975 which go 3 decimal places is 6.298 meters
Using the regression model given, substitution the value of x = 2.5 minutes into the equation, the dive depth obtained ls 6.2975 meters.
Given the regression model :
y = 0.010 + 2.515xx = time of the dive ; y = dive depthConverting, x to minutes :
150 seconds = (150 ÷ 60) = 2.5 minutes
The dive depth, y after 150 seconds, can be obtained by substituting the value x = 2.5 into the equation :
y = 0.010 + 2.515(2.5)
y = 0.010 + 6.2875
y = 6.2975
There, the dive depth after 150 seconds will be 6.2975 meters

Jason spent a total of $131 on shirts. Dress shirts cost $28 dollars and T-shirts cost $15 dollars. If he brought 7 shirts how many of each kind did he buy?
Answer: 28x + 15y = 131 and x + y = 7 where x is the number of Dress shirt and y is the number of T-shirt.
Step-by-step explanation:
We will represent the number of Dress shirt he bought by x and we will represent the number of T-shirt he bought by y.
We know that he spent 131 so the cost of each dress shirt plus the cost of each T-shirt has to equal 131. Also, he bought 7 total shirts so x plus y has to equal 7.
28x + 15y = 131
x + y = 7

What is the unit rate?
y=5x
Answer:
In the equation y=5x the slope (m) is 5, and the y-intercept is the point (0,0) since there is nothing added or subtracted to the 5x, and thus b = 0.

Step-by-step explanation:
Perhaps the easiest way to do this is to find the roots of the given equation, then write the equation that has reciprocal roots. The given equation can be factored as ...
(2x -1)(3x -1) = 0 ⇒ roots 1/2, 1/3
Then the factoring of the equation with reciprocal roots is ...
