5 pounds of bananas for $1.97 for 3 pounds of bananas for $1.05 which is better to buy
Answer:
3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.Step-by-step explanation:
We need to find the unit rate. This found by dividing the price by the number of bananas so we get the price for 1 pound of bananas.
$1.97/5 = $0.39
$1.05/3 = $0.35
3 pounds for $1.05 is better since it is 35 cents a pound as opposed to 39 cents a pound for the other product.Justin has $28 to buy a gift for his cousin, Julianne. He found something to buy that costs $24. He knows he has to also pay 8% in sales tax and he is trying to decide if he can afford it. Will he have enough money to buy the item and if so how much will he pay?
Justin will have enough money to buy the item. The amount Justin will pay is $25.92.
How much will Justin pay?A sales tax is the amount of tax that is charged on the sales of goods and services. Tax is the compulsory sum levied by the government or an agent of the government on goods and services. Taxes increase the price of an item.
Percentage is the fraction of an amount expressed as a number out of hundred. The sign used to represent percentages is %.
Amount Justin would pay for the item = (1 + tax) x initial cost of the item
(1 + 0,08) x $24
= 1.08 x 24 = $25.92
$25.92 is less than the amount Justin has for the gift. This means that Justin has enough money to buy the gift.

Raoul is trying to find a new way to keep track of coffee beans. He can fit 1,000 beans in a tub, 100 beans in a large bag, and 10 beans in a small bag. He leaves any group of 9 or less on his counter. If Raoul has 2 tubs, 3 large bags, 1 small bag, and 5 beans on the counter, how many coffee beans does Raoul have altogether?
Answer:
2,315 coffee beans.
Step-by-step explanation:
1 tub = 1,000
1 large bag= 100
1 small bag = 10
Raoul has:
- 2 tubs
- 3 large bags
- 1 small bag
- 5 beans on the counter
2 x 1,000 = 2,000
3 x 100 = 300
10 + 5 = 15
then, add all of the (bold) numbers together.
2,000 + 300= 2,300
2,300 + 15 = 2,315
Raoul has 2,315 beans altogether.
is it less, greater or equal pls help (will give brainleist)

HELP ME!!!!!! h(x) = -(x + 2)2 + 8 what is the axis of Symmetry
Answer:
The vertical line [tex]x = -2[/tex] is the axis of symmetry of [tex]y = -(x + 2)^{2} + 8[/tex].
Step-by-step explanation:
For the graph of a quadratic function, the axis of symmetry is the vertical line that goes through the vertex of this function.
In general, if the vertex of a quadratic function is at [tex](x_{0},\, y_{0})[/tex], the vertex form equation of this function would be [tex]y = a\, (x - x_{0})^{2} + y_{0}[/tex] for some non-zero constant [tex]a[/tex] ([tex]a \ne 0[/tex].)
Rewrite the quadratic equation in this question [tex]y = -(x + 2)^{2} + 8[/tex] to match the vertex form:
[tex]y = -(x + 2)^{2} + 8[/tex].
[tex]y = (-1)\, (x - (-2))^{2} + 8[/tex].
Thus:
[tex]a = (-1)[/tex].[tex]x_{0} = (-2)[/tex].[tex]y_{0} = 8[/tex].Hence, the vertex of this parabola would be at [tex](-2,\, 8)[/tex].
Again, the axis of symmetry of this graph would be a vertical line that goes through this vertex. The [tex]x[/tex]-coordinate of this vertical line would be [tex](-2)[/tex]. The equation of this vertical line would be [tex]x = (-2)[/tex].
Hence, the axis of symmetry of this quadratic function would be [tex]x = (-2)[/tex].

What is an mathematical expression?
Expression in mathematics is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Here, it is given that :
Ella works two part-time jobs, one before school and one after school. Before school, she earns $11.25/hour, and after school "a" she earns $11..75/hour and She works twice as many hours after school that is :
a = 2b ......(1)
also, 11.25a + 11.75b = 278....(2)
now, solving for a and b :
11.25a + 11.75b = 278
11.25(2b) + 11.75b = 278
b = 278/34.25
b ≈ 8 hours
Now, the value of a will be 2b = 16 hours
Therefore, the Ella works 16 hours after school and 8 hours before school.

the department of education wishes to estimate the proportion of all college students who have a job off-campus. it surveyed 1600 randomly selected students; 451 had such jobs. the population of interest to the department of education is:
The population of interest to the department of education will be all college students.
A population is a large group of individuals that have some common feature by the researcher's point of interest.
Here the Department of Education wishes to estimate the proportion of all college students who have a job off-campus.
Proportion: A proportion is an equation in which two ratios are set equal to each other. If there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls) 1 / 4 are boys and 3 / 4 are girls. 0.25 are boys (by dividing 1 by 4).
So , he needs data of all students to compute the exact proportion.
But instead of that he surveyed 1600 randomly selected students which determine the sample.
Sample just gives the estimate of the parameter.
Hence, the population of interest to the Department of education is " All college students" .

Lin has two small baking pans, each shaped like a rectangular prism. For each question, explain or show your reasoning.
a. Lin lines the bottom of her first pan with aluminum foil. The area of the rectangular piece of foil is 1114 square inches. Its length is 412 inches. What is the width of the foil?
b. Lin's second pan has a length of 83 inches, a width of 154 inches, and the height of 32 inches. What is the volume of the second pan?
Answer:
2 1/2
Step-by-step explanation:
( 11 1/4 ) / ( 4 1/2 ) = 2 1/2
( 2 1/2 ) = 5/2
The width of the pan is 2.70 inches.
The volume of the pan is 409,024 inches³
A rectangular prism is a polyhedron with six faces and twelve edges. It is also known as a cuboid.
The width of the foil can be determined by dividing the area by the length.
Width = area / length
1114 / 412 = 2.70 inches
Volume of the pan =length x width x height
83 x 154 x 32 = 409,024 inches³

Answer:
the answer is 600mph
Step-by-step explanation:
because 1800miles/3 hours=600mph
Answer:
600 mph
Step-by-step explanation:
In order to find the answer you must solve using this formula:
S=D/T
Where S is speed, D is distance, and T is time
You have time and distance, so you have to plug those into the formula:
S=1800/3
Then all you have to do is divide 1800/3 and get 600 for speed.

Beula has a collection of video games. There are 12 games in the collection, and 2/4 of them are console games. Beula decides to double the amount of console games. 1. How many console games are in the collection now? 2. What fraction the games are console games now?
Answer:
12 console games
Step-by-step explanation:
if 2/4 are console games when you have 12, that means 6/12 are console games so to double the amount, add 6. 12+6=18.
12 out of the 18 are now console games making console games 6/9 (2/3 simplified) of the game collection.
