Answer:
$6.48
Step-by-step explanation:
The discount is 10%. That means you pay 90% of the price.
At the regular price, 4 1/2 lb of bananas cost:
$1.60/lb * 4.5 lb = $7.20
Since with the 10% discount, you pay 90% of the original price, now we calculate 90% of the original price.
90% of $7.20 = 0.9 * $7.20 = $6.48
Answer: 4.5 lb cost $6.48 with the 10% discount

A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
The area of the living room wall = The area of the rectangle
The amount of paint needed to cover one wall is 240 square feet.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
Example:
The area of a rectangle with length 2cm and width 3cm is 6cm².
We have,
A living room wall is 20 feet long, and 12 feet high.
The living room can be considered a rectangle.
Length = 20 feet
Width = 12 feet
The area of the living room wall = Area of a rectangle
Now,
Area of the living room wall.
= 20 x 12
= 240 square feet
Thus,

Anna enjoys dinner with her family at a restaurant in Washington, D.C. She leaves a 15% tip on the price of her meal. She also has to pay a 10% sales tax on her meal, which is calculated on the pre-tip amount. She spends a total of $27.50 for dinner, including tax and tip. What is the cost of her dinner without tax and tip? Show your work.
Answer:
$22
Step-by-step explanation:
tax and the tip increase the price paid for the meal
she paid 15 + 10 = 25% more than the price of her meal
p = original price
1.15 x p = 27,50
p = 27.50 / 1.15 = 22

The double cone is intersected by a vertical plane passing through the point where the tips of the cones meet. What is the shape of the cross
section formed?
For each set of angles or sides lengths, determine whether they could form a unique triangle, more than one triangle, or no triangle.
5 cm, 10 cm, 12 cm
8 ft, 12 ft, 20 ft
40°, 50°, 80°
28°, 51°, 101°
Answer: They can form one triangle.
Step-by-step explanation: Since all triangle must have 180 degrees, there’s only one set of degrees that sum up to 180.
28+51+101=180
I’m sorry, but the feet/centimeters part you have to solve on your own. Remember, this is a learning community! No stress :) I can guarantee you won’t get it wrong though.
There’s many different triangles, and I’m sure from these feet/centimeters you can make at least one of the listed: Scalene (none of the sides are equal), isosceles (only 2 sides are equal) or equilateral triangle (all sides are equal). There’s also right triangles (which are triangles with one right angle also known as 90 degrees) that are either isosceles or scalene or both! Try your best and remember, no stress :)
Si a una persona le deben 7/9 de $450000 y sólo le cancelan 3/5 de esa deuda. ¿Cuánto dinero le quedan debiendo?
Answer:
$140,000
Step-by-step explanation:
Paso 1
Si a una persona le deben 7/9 de $ 450,000
La cantidad que se le debe a la persona se calcula como:
7/9 × $ 450,000
= $ 350,000
Paso 2
Solo se cancela 3/5 de esa deuda.
El monto de la deuda que se cancela se calcula como:
3/5 × $ 350,000
= $ 210,000
Paso 3
Por lo tanto, la cantidad de dinero que debe se calcula como:
$ 350,000 - $ 210,000
= $ 140,000

Mother has 1 kg of tomatoes.She gave 1/4 to aling nena and 3/8 to aling ana.How many kilograms of tomatoes was left to mother
Answer:
3/8 kg of tomatos
Step-by-step explanation:
1/4 * 2 = 2/8
2/8 + 3/8 = 5/8
1 - 5/8 = 3/8
The amount of tomatoes was left to the mother in kilograms will be 0.375 kilograms.
What is Algebra?Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.
Mother has 1 kg of tomatoes.
She gave 1/4 to aling nena and 3/8 to aling ana.
Then the amount of tomatoes was left to the mother in kilograms will be
Let x be the amount of tomatoes.
x = 1 - 1 × 1/4 - 1 × 3/8
x = 1 - 0.25 - 0.375
x = 1 - 0.625
x = 0.375 kilograms

The mean age of 5 women in an office is 23 years old. The mean age of 3 men in an office is 24 years old. What is the mean age (nearest year) of all the people in the office?
Answer:
23
Step-by-step explanation:
Women total age = 5 x 23 = 115
Men total age = 3 x 24 = 72
The mean age of all the people
= (115+72)÷(8)
= 23.375
= 23 (nearest year)
The mean age (nearest year) of all the people in the office is 23
How to determine the mean age?The given parameters are:
5 women = 23 years
3 men = 24 years
Mean is calculated using:
[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]
So, we have:
[tex]\bar x = \frac{23 * 5 + 24 * 3}{5 + 3}[/tex]
Evaluate the quotient
[tex]\bar x = 23[/tex]
Hence, the mean age (nearest year) of all the people in the office is 23

1.3. If Sara draws a red ball and DOES NOT RETURN it, and then she goes to draw a green
ball, is this considered a dependent or independent event?
Answer:
Dependent Event
Step-by-step explanation:
Assume that are 10 balls, such that:
[tex]Red = 6[/tex]
[tex]Green = 4[/tex]
If the balls are replaced after taken, the probability is:
[tex]Pr(Red) = 6/10[/tex]
[tex]Pr(Green) = 4/10[/tex]
This is referred to as independent event; because each selection do not affect the next or previous selection
However, if the balls are not replaced, the probability is:
[tex]Pr(Red) = 6/10[/tex]
[tex]Pr(Green) = 5/(10 - 1) = 5/9[/tex]
We subtracted 1 because there is a reduction in the number of balls when the red ball is not returned.
This is referred to as independent event; because a selection affects the next selection

1. Find the measure of arc ABC
110 °
Answer:
Arc ABC = 250°
Step-by-step explanation:
m<AOB = 110° (given)
Based on the central angle theorem, central angle m<AOB equals the intercepted arc AB
Therefore,
m<AOB = measure of arc AB = 110°
Thus:
Arc ABC = 360° - arc AB (Full circle = 360°)
Arc ABC = 360° - 110°
Arc ABC = 250°
Determine which gym's membership grows faster from Month 2 to Month 4 by calculating the average rates of change.
Answer:
Gym A is growing faster
Gym A gained 13 members between months 2 and 4
Gym B gained 10 members between months 2 and 4
Step-by-step explanation:
Gym A: (2,20) (4,46)
rate of change = (46-20)/(4-2) = 26/2 or 13
Gym B: (2,40) (4,60)
rate of change = (60-40)/(4-2) = 20/2 or 10
What is the area of this triangle
Answer:
This is kinda hard to answer, but i'm going to say the answer might be 14 cm squared.
Step-by-step explanation:
I don't have much info, but I can say that the 7 cm side can be split into 2 lengths of 5 cm, and 2 cm.
Using this i can do 5 times 4 to get 20, but sense it's a triangle, the triangle would be half of a square making it 10 cm for the left part of the triangle.
Using the knowledge of the left triangle, I can do 2 times 4, which equals 8, half of 8 cm is 4 cm, and now i can do the equation of 10 cm plus 4 cm equals the answer of 14 cm squared.
In a completely randomized design involving three treatments, the following information is provided:Treatment 1Treatment 2Treatment 3Sample Size5105Sample Mean489The overall mean for all the treatments is _______.

Step-by-step explanation:
Given :
___________ Sample size __ sample mean
Treatment 1 ____ 5 _______ 4
Treatment 2 ____ 10 ______ 8
Treatment 3 ____ 5 _______ 9
Sample size = (5 + 10 + 5). = 20
Overall mean = ((5*4). + (10*8) + (5*9)) / 20
Overall mean = (20 + 80 + 45) / 20

Answer:
7/21 x 10/20
1/3 x 1/2 = 1/6
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one is attached to the event. If it doesn't a value of zero is attached to the event.
probability of picking a white marble first = total number of white marbles / total number of marbles = 7/21
probability of picking a green marble second = total number of green marbles / total number of marbles = 10/20
7/21 x 10/20
1/3 x 1/2 = 1/6

Answer:
Get a ruler
Step-by-step explanation:
I can't really answer this because it's a measuring problem.
But I'll walk you through it.
First, grab your ruler. Once you have it, you're gonna measure the icon, so the square picture. Make sure you measure it in centimeters (cm). Measure EACH side. Once you have the measurement of each sides, add them up to get your perimeter. The perimeter will always be length + width + length + width.
To find the area, take your length and your width and multiply them together.
For the second problem, you're going to take your measured side and multiply EACH of them by 2.5. The scale 1 cm = 2.5 mm means that for every represented centimeter in the image, the actual image is 2.5 mm. Once you have multiplied each sides by 2.5, you're going to repeat the steps above to get the perimeter and the area.
