A store is having a sale on jelly beans and almonds for 3 pounds of jellybeans in 2 pounds of almonds the total cost is $10 for 5 pounds of jellybeans in 6 pounds of almonds the total cost is $24 find the cost of each pound of jellybeans and each pound of almonds
Answer:
each lb of jellybeans = $1.50
each lb of almonds = $2.75
Step-by-step explanation:
let j = jellybean cost for each pound
let a = almond cost for each pound
3j + 2a = 10
5j + 6a = 24
Using elimination method:
15j + 10a =50
15j + 18a = 72
------------------------
-8a = -22
a = 2.75
using 3j + 2a = 10
3j + 2(2.75) = 10
3j + 5.5 = 10
3j = 4.5
j = 1.5

Use the following situation for the next few questions:
At Elsa's auto shop, it takes her 12 minutes to do an oil
change and 15 minutes to do a tire change. Let x be the
number of oil changes she does. Let y be the number of tire
changes she does. We are wondering what combinations of
the two tasks she can complete in 60 minutes or less.
1-If Elsa were to only do oil changes, no tire changes, how
many could she do in 60 minutes or less?
Answer:
5 oil changes.
Step-by-step explanation:
60 = 12x + 15y
60 = 12x + 15(0)
60 = 12x + 0
60
---- = x
12
5 = x
3. Find the surface area of the square pyramid.
plzzz helppp i will give brainliest
Answer:
Hello! answer: 105
Step-by-step explanation:
When doing these for squares you have to do base × height and for triangles you do base × height ÷ 2 So Lets do the triangles sense there more complex so we can get them out of the way. The base for the triangles our 5 and the height is 8 so we will do 5 × 8 = 40 now we will just divide that by 2 so 40 ÷ 2 = 20 now sense we have four identical triangles we will just multiply 20 by 4 so 20 × 4 = 80 now for the 1 in the middle its nice and simple just 5 × 5 so 5 × 5 = 25 now we just add 80 + 25 and 80 + 25 = 105 So 105 is the area! Hope that helps!

Step-by-step explanation:
Assuming you're looking to find the missing angle measure, remember that in inscribed angles, such as angle DEF, the measure of the angle is half the measure of its intercepted arc. That means that the missing angle is half the measure of 228, which is 114, C.

Answer:
Mirror
Step-by-step explanation:
Two friends Ana and Juan are buying books by joining the History Book
Club.
Ana has to pay a yearly fee of $15 to join. She spends a total of $525 for 30
books. How much was the price per book on average?
Juan has to pay a yearly fee of $10 to join. He spends a total of $350 for 23
books. How much was the price per book on average?
Write a function for Ana and Juan each to model the scenario to figure out
the total cost per book. Who has the better deal? Ana or Juan? Why?
Answer:
Ana spent $17 per book on average.
Juan spent $14.78 per book on average.
y = $15 + 17x--------- equation 1
y= $10 + 14.78 x------------- equation 2
Step-by-step explanation:
Ana has to pay a yearly fee of $15 to join.
She spends a total of $525 for 30 books.
The amount spent on books = Total amount - yearly fee
= $525- $15= $510
Price per book on the average = $510/30= $ 17
Ana spent $17 per book on average.
Juan has to pay a yearly fee of $10 to join.
He spends a total of $350 for 23 books.
The amount spent on books = Total amount - yearly fee
= $350- $10= $340
Price per book on the average = $340/23= $ 14.78≅ $15
Juan spent $14.78 per book on average.
The function can be established if y gives the total cost and x gives the number of books
y = $15 + 17x--------- equation 1
y= $10 + 14.78 x------------- equation 2
Juan has a better deal because the yearly fee is less also the price per book is less.
write a pair of integers whose a)sum-1 b)diffrence is -5
please give the answer only last question in my test
Answer:
x = -3
y = 2
Step-by-step explanation:
Let the two integers be x and y
sum is -1
x + y = -1 •••(i)
x-y = -5 •••••(ii)
From ii, x = -5 + y
substitute into i
-5 + y+ y = -1
-5 + 2y = -1
2y = -1 + 5
2y = 4
y = 4/2
y = 2
Recall;
x = -5 + y
x = -5 + 2
x = -3
Write the model of a 50 gram substance that decays at a rate of 3% yearly
Answer:
A(t) = 50(0.97)^t
Step-by-step explanation:
3% = 0.03
1 - .03 = 0.97
A(t) = 50(1 - 0.03)^t
A(t) = 50(0.97)^t
Classify the following triangle in as many ways as possible.
what percent of 4$ is 60 cents
no links
Answer:
15%
Step-by-step explanation:
You kind of have two ways to do this:
Way 1:
Find how many 60 cents fit into $4. To do that, divide $4 by $0.60 or 400 by 60. You get 6.66666667.
You can divide 100 by 6.66666667, and get 15%,
Way 2:
Knowing that 400 cents is 100%, you can divide 60 by the same number that you divide 400 by to get to 100. To get from 400 to 100, you divide by 4, so divide 60 by 4 and get the same answer, 15%
Hope that helps :)

Answer:
∠C ≈ 11.978°
Step-by-step explanation:
sin (∠C)/5 = sin (95°)/24
=> sin (∠C) = 5 × sin (95°) ÷ 24
=> ∠C = [tex]sin^{-1}[/tex](5 × sin (95°) ÷ 24)
=> ∠C ≈ 11.978°
The circumference of a circle is 28. Contained in that circle is a smaller circle with area 36π. A point is selected at random from inside the large circle. What is the probability the point also lies in the smaller circle?
Answer:
[tex]Pr = \frac{9}{49}[/tex]
Step-by-step explanation:
Given
[tex]d = 28[/tex] --- big circle
[tex]A_2 = 36 \pi[/tex] --- area of small circle
Required
Probability that a point selected lands on the small circle
Calculate the area of the big circle using;
[tex]A_1 = \pi r^2[/tex]
Where
[tex]r = d/2[/tex]
So, we have:
[tex]r = 28/2 = 14[/tex]
This gives:
[tex]A_1 = \pi * 14^2[/tex]
[tex]A_1 = \pi * 196[/tex]
[tex]A_1 = 196\pi[/tex]
The probability that a point selected lands on the small circle is calculated by dividing the area of the small cicle by the big circle
This gives:
[tex]Pr = \frac{36\pi}{196\pi}[/tex]
[tex]Pr = \frac{36}{196}[/tex]
Simplify
[tex]Pr = \frac{9}{49}[/tex]
A group of friends wants to go to the amusement park. They have $387.75 to spend on parking and admission. Parking is $5.50, and tickets cost $34.75 per person, including tax. How many people can go to the amusement park?
Answer:
Step 1:
Subtract $19 from total
366.50 - 19 = 347.5
Step 2:
Divide this total by the ticket price
347.50 / 34.75 = 10
Step 3:
You have your answer
10 people can go to the amusement park
Answer:
as many as 11 people
Step-by-step explanation:
n = # of people
5.50 + 34.75n ≤ 387.75
subtract 5.5 from each side to get:
34.75n ≤ 382.25
divide each side by 34.75
n ≤ 11
Josh wrote 483 out of an expected 500 words from his essay. How would this ratio be
expressed in decimal form?
Answer:
0.966
Step-by-step explanation:
483:500 = 0.966
i hope this is right x
The required ratio would be 0.966 which is expressed in decimal form.
What is the Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Josh wrote 483 out of an expected 500 words from his essay which is given in the question.
According to the given information, the ratio would be written as:
⇒ 483 : 500
⇒ 483 / 500
Apply the division operation, and we get
⇒ 0.966
Therefore, the required ratio would be 0.966 which is expressed in decimal form.

What is the perimeter of a rectangle whose vertices are (2,7) (8,7) (211) (8,11)?
A) 24
b) 12
c)32
d) 40
e) 20
Answer:
e) 20
Step-by-step explanation:
Segment lengths:
|(2, 7) -> (8, 7)| = |(8-2, 7-7)| = |(6, 0)| = 6
|(8, 7) -? (8, 11)| = |(8-8, 11-7)| = |(0, 4)| = 4
because we know it's a rectangle, we can infer that the other two sides also have lengths 4 and 6, so the perimeter is 4+4+6+6=20

Answer:
330 miles
Step-by-step explanation:
The distance formula can be used to find the number of grid units between points.
d = √((x2 -x1)^2 +(y2 -y1)^2)
AC = √((-2-11)^2 +(6-(-2))^2) = √((-13)^2 +8^2) = √(169+64) = √233 ≈ 15.264
CD = √((-8-(-2))^2 +(9-6)^2) = √((-6)^2 +3^2) = √(36 +9) = √45 ≈ 6.708
Then the total distance in miles is ...
(15.264 units +6.708 unit)(15 miles/unit) ≈ 329.59 miles
Rounded to the nearest mile, the distance is 330 air miles.
