How can you use the unit price to find the cost of 10
pounds of tomatoes? Please help
Answers
To find the cost of 10 pounds of tomatoes, multiply 10 by the unit cost of tomatoes.
What is the unit cost?
The cost a business incurs to create, store, and sell one unit of a specific product is known as the unit cost. All fixed and variable production expenses are included in unit costs. Cost units are a way to measure the quantity of a good or service.
Unitary method: The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
The unitary method is used to find the unit cost of an object.
To find the cost of a unit object, multiply a by unit cost.
Given that, the unit cost of a unit pound of tomatoes.
The cost of 10 pounds of tomatoes is 10 × unit price of tomatoes.

At Juicy Deals grocery store, 4 oranges
cost $7.00. You can buy 7 oranges
for $12.50.
Is the relationship between the number of
oranges and their price proportional?
Explained step by step please
Answers
Answer:
True
Step-by-step explanation:
Let's call
x: number of oranges
y: price
The relationship between x and y is proportional if they fulfill the following condition.
y / x = k
where,
k is a proportionality constant
Then,
6 / 4 = 15 / 10 = 1.5
Since x and y fulfill the condition, they have a relationship of proportionality.

The piggy bank has 71 dimes and quarters with a
value of 12.35 dollars. How many of each coin are there
Answers
Answer:
35 Quarters and 36 Dimes
Step-by-step explanation:
d + q = 71
10 + 25 = 1235
10 x 36 = 360
25 x 35 = 875
360 + 875 = 1235
Answer:
There are 35 quarters and 36 dimes.
Step-by-step explanation
x = the number of quarters
y = the number of dimes
x + y = 71
0.25x + 0.1y = 12.35 ---> multiply this equation by 100
now...
25x + 10y = 1235
x + y = 71 ----> multiply this equation by -25
25x + 10y = 1235
-25x - 25y = -1775
[tex]\frac{-15}{-15} = \frac{-540}{-15}[/tex]
y = 36 dimes
next step
x + y = 71
x + 36 = 71
- 36 - 36
x = 35 quarters
a parallelogram has sides that are in the ratio of 7:5 the premeter of the parallelogram is 48 how long does the longer side
Answers
Hello there!
Answer:
14
Step-by-step explanation:
Let the smaller side is x. Then the largest side is x * 7/5.
Perimeter is equal to 2 * (x + 7/5 * x) or 48.
2 * (x + 7/5 * x) = 48
5/5 * x + 7/5 * x = 24
12/5 * x = 24
12/5 * 5/12 * x = 24 * 5/12
x = 10.
Tha larger side is 10 * 7/5 = 14.
Step-by-step explanation:
Given ,
Ratio of the sides of a parallelogram are 7:5Perimeter of a parallelogram is 48To Find : Which side is longer
We know the formula to find the perimeter of a parallelogram is,
[tex]P = 2(a+b)[/tex]
We take 'x' to find out which side is longer
[tex]48 = 2(7x+5x)\\48 = 2(12x)\\48 = 24x\\\frac{48}{24} = x[/tex]
[tex]2 = x[/tex]
Side a = 7x = 7 x 2 = 14
Side b = 5x = 5 x 2 = 10
Side a [tex]\geq[/tex] Side b
Hence, side a is longer

Each year, the high school guidance counselors conduct a survey to estimate the proportion of students at the school who cheat on their homework. Based on a random sample of 300 students from the high school, a 99% confidence interval for the proportion of all students at the high school who cheat on their homework is 0.052 to 0.192. Describe how untruthful answers might lead to bias in this survey. Does the stated margin of error account for this possible bias
Answers
Answer:
The stated margin of error would account for the possible bias caused by wrong answers due to the closeness of the confidence interval
Step-by-step explanation:
Random sample = 300
99% confidence interval of student who cheat : 0.052 to 0.192
The confidence interval is too close that it only contains the population parameter, this means that almost every subject in the Given population will have to be measured.
Since This is an impractical approach it will lead to untruthful answers been produced which will cause bias. hence the stated margin of error would account for the possible bias caused by wrong answers.

From a point 235 meters from the base of a cliff, the angle of elevation to the cliff top is 25 degrees. Find the height of the cliff.
please provide a diagram and step by step answers thanks
Answers
Answer:
X=110
Step-by-step explanation:
The height of the cliff is 109.58 meters.
What is Angle of Elevation?Angle of elevation is the angle which is between a horizontal line and the line of sight which is pointed upwards.
Given that,
We get a right angled triangle ABC where A represents the base of the cliff and C is the point of the top of the hill.
B is the point which is at a distance of 235 meters from the base of a cliff.
Length of AB = 235 meters
Angle of elevation to the cliff top, ∠B = 25 degrees
AC represents the height of the cliff. Let it be x.
Using the trigonometric ratio,
tan B = AC / AB
tan 25 = x / 235
x = 235 × tan 25
= 109.58 meters
Hence the height of the cliff is 109.58 meters.

Answer:

40 equals the total amount of teachers. Since we want to do the ratio of math teachers to the total of all teachers, we had to find 40.
You get 14:20 though if you want to simplify, find to common denominator (2) and dived both sides by it.

a line has a slope of 5. it passes through the points (-5, -1) and (x, 9). what is the value of x?
Answers
A line has a slope of 5. it passes through the points (-5, -1) and (x,9) than the value of x is -3
We are going to use the fact that when a line passes through two points : [tex](x1,y1) and (x2,y2)[/tex]
the slope is given by the following formula:
[tex]slope=y2-y1/x2-x1[/tex]
In the present case, the slope is 5 and the points are (-5, -1) and (x, 9)
Hence,
[tex]5=9-(-1)/x-(-5)[/tex]
[tex]5=10/x+5\\x+5=10/5\\x+5=2\\x=-3[/tex]
Thus, the value of x is -3 when it travels between the coordinates (-5, -1) and (x, 9).

O Both the amount of wood required and the amount of glass required have a constant rate of change.
ONeither the amount of wood required nor the amount of glass required has a constant rate of change.
Answers
Answer:The combined functions W(x) and G(x) represent the amount of wood and glass required to produce a picture frame. Based on the information provided,
W(x)= 2[(f+g)(x)] and G(x) = (f-g)(x)
By looking at the values of the given table, it can be observed that the rate of change in the amount of glass required (G(x)) is not constant, it increases as x increases.
On the other hand, the rate of change in the amount of wood required (W(x)) is not constant as well, it increases as x increases too.
It's not mentioned any information about constant rate of change for f and g.
Therefore, the correct statement that describes the combined functions W(x) and G(x) is: "Neither the amount of wood required nor the amount of glass required has a constant rate of change."
It's important to mention that the problem provided does not have a unique solution, because the values for f and g are not defined so it's not possible to infer their behaviour over time.
It is only possible to infer the behaviour of the functions W(x) and G(x) given the information provided, and it is clear that the rate of change for both functions does not remain constant, but it increases as x increases.

A=[2 3) B=(1 2) find AB
[0 8) (2 -1)
Answers
Answer: To find the product of two matrices A and B, we must use the matrix multiplication rules.
Matrix A is a 2x2 matrix with values [2 3; 4 5] and matrix B is a 2x2 matrix with values [1 2; 3 4].
The result of matrix multiplication, AB, will also be a 2x2 matrix.
To find each element in the resulting matrix, we take the dot product of the corresponding row in matrix A and column in matrix B.
The first element in the resulting matrix AB, is found by taking the dot product of the first row in matrix A and the first column in matrix B:
(21) + (33) = 2+9 = 11
The second element in the resulting matrix AB, is found by taking the dot product of the first row in matrix A and the second column in matrix B:
(22) + (34) = 4+12 = 16
The third element in the resulting matrix AB, is found by taking the dot product of the second row in matrix A and the first column in matrix B:
(41) + (53) = 4+15 = 19
