One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?
A First one
B second one
C third one
D last one
Answer:
A
Step-by-step explanation:
One pound of grapes costs $1.55. To find the amount x of 3.5 pounds of grapes we would have to multiply 1.55 by 3.5. This would give us the amount x we would have to pay for them.
If we examine the 4 equivalent radios shown in the pictures, we will see that the first one correctly shows this equivalency.
[tex]\frac{1.55}{1} = \frac{x}{3.5}[/tex]
The other 3 pictures show radios that would give us x = 3.5 / 1.55 (second and third) or x = 1.55 / 3.5 (fourth picture).
Therefore, the correct answer would be a)

jeff finds some bugs. he finds 10 fewer grasshoppers than crickets. he finds 5 few crickets than ladybugs. if jeff finds 5 grasshoppers. how many ladybugs does jeff find? how many crickets does he finds?
Jeff found 15 crickets and 20 ladybugs
Let the number of grasshoppers be x
Let the number of crickets be y
Let the number of ladybugs be z
If Jeff finds 10 fewer grasshoppers than crickets, hence x = y - 10
If he finds 5 few crickets than ladybugs, hence y = z - 5
If jeff finds 5 grasshoppers, hence x = 5
Since x = y - 10
5 = y - 10
y = 5 + 10
y = 15
Similarly since y = z - 5
15 = z - 5
z = 15 + 5
z = 20
This shows that Jeff found 15 crickets and 20 ladybugs

which of the following equations represents a direct variation?
A y=x -1
B y=×/3
C y = x + 5
D y = 2x-3
The equation represents a direct variation is y = x/3. So option (b) is correct.
A direct variation is a relationship between two variables where one variable is a constant multiple of the other. To identify a direct variation, we look for equations in the form y = kx, where k is a constant.
Let's analyze each equation:
A) y = x - 1
This equation doesn't represent a direct variation because it includes a constant term (-1) in addition to the variable x.
B) y = x/3
This equation represents a direct variation because it's in the form y = kx, where k = 1/3.
C) y = x + 5
Similar to option A, this equation doesn't represent a direct variation because it includes a constant term (+5) in addition to the variable x.
D) y = 2x - 3
Similar to option A, this equation doesn't represent a direct variation because it includes a constant term (-3) in addition to the variable x.
Therefore, the correct answer is B) y = x/3, as it represents a direct variation.

Geneva rode her bike a total of 2 1/2 miles from her house to school. First she rode 4/5 mile from her house to the park. Then she rode 1/5 mile from the park to her friends house . Finally she rode the rest of the way to her school? How many miles did she ride from her friends house to school
Answer:
She rode [tex]1\frac{1}{2}[/tex] miles from her friends house to school.
Step-by-step explanation:
Geneva rode her bike a total = [tex]2\frac{1}{2}[/tex] miles
She rode from her house to the park = [tex]\frac{4}{5}[/tex] miles
She rode from the park to her friend's house = [tex]\frac{1}{5}[/tex] miles
total distance from her house to her friend's house = [tex]\frac{4}{5}+\frac{1}{5}[/tex] = 1 mile
Finally she rode the rest of the way to her school.
distance between her friend's house to school = [tex]2\frac{1}{2}-1[/tex] = [tex]\frac{3}{2}[/tex] miles

A company borrowed $25,000 at 3.5% and was charged $2,625 in interest. How long was it before the company repaid the money?
Answer-
The company repaid the money in 3 years.
Solution-
A company borrowed $25,000 at 3.5% and was charged $2,625 in interest.
Considering the interest as simple interest,
[tex]\text{interset}=\dfrac{\text{Principal}\cdot \text{Rate of interest}\cdot \text{Time period}}{100}[/tex]
Here,
Interest = $2625
Principal = $25000
Rate of interest = 3.5% annually
Putting the values,
[tex]\Rightarrow 2625=\dfrac{25000\times 3.5\times t}{100}[/tex]
[tex]\Rightarrow t=\dfrac{2625\times 100}{25000\times 3.5}[/tex]
[tex]\Rightarrow t=3\ years[/tex]
Therefore, the company repaid the money in 3 years.
Find the probability and interpret the results. if convenient, use technology to find the probability. during a certain week the mean price of gasoline was $2.715 per gallon. a random sample of 32 gas stations is drawn from this population. what is the probability that the mean price for the sample was between $2.691 and $2.732 that week? assume sigmaσequals=$0.049
To find the probability of the sample mean price being between $2.691 and $2.732, calculate the Z-scores for each bound and use a Z-table or statistical software. This utilizes the central limit theorem and the concept of Z-scores in statistics.
Explanation:The question is about finding the probability that the mean price for a sample of 32 gas stations was between $2.691 and $2.732, assuming the population mean was $2.715 and standard deviation was $0.049. To solve this, we use the Z-score formula for each sample mean, Z = (X - μ) / (σ/√n), where μ is the population mean, σ is the population standard deviation, and n is the sample size. Then, we find the area between these Z-scores using a Z-table or statistical software to get the probability.
To calculate:
For $2.691: Z = ($2.691 - $2.715) / ($0.049/√32) = -3.44For $2.732: Z = ($2.732 - $2.715) / ($0.049/√32) = 2.45Refer to a Z-table or software with these Z-scores to find the probability of the sample mean price being between $2.691 and $2.732. This method exemplifies how statisticians use Z-scores and the central limit theorem to estimate probabilities relating to sample means.

the vertex of this parabola is at (3,5). When the y-value is 6, the x-value is -1. What is the coefficient of the squared term in the parabolas equation
The coefficient of the squared term in the parabola's equation, with a vertex at (3,5) and passing through the point (-1,6), is 1/16.
The student is asking about the coefficient of the squared term in the parabola's equation given that the vertex is at (3,5) and another point on the parabola is (-1,6). Since we know the vertex, we can write the vertex form of a parabolic equation as:
y = a(x - h)
^2 + k
Plugging the vertex into the equation, we get:
5 = a(3 - 3)
^2 + 5
This simplifies down to:
5 = a(0) + 5
So, we cannot determine 'a' from the vertex alone. However, we can use the other point to find 'a'. Plugging the coordinates (-1,6) into the vertex form, we get:
6 = a(-1 - 3)^2 + 5
6 = a(-4)^2 + 5
6 = 16a + 5
1 = 16a
a = 1/16
Therefore, the coefficient 'a' is 1/16.

Step-by-step explanation:
Jane is saving her money in order to purchase a new racing bike. She initially saves $3 and plans to double the amount she saves each month.
he bike Jane wants is $1,536 at the local bike shop.
The equation that represents this situation, and after how many months, t, will Jane have enough money to purchase the bike is:
D) 3×(2)^t = 1,536; t = 9
since in the first month the cost is:
[tex]C_1=3\times 2[/tex]
in next month the cost is:
[tex]C_2=3\times 2\times 2\\\\C_2=3\times 2^2[/tex]
in t=3 months the expression is:
[tex]C_3=3\times 2^2\times 2\\\\C_3=3\times 2^3[/tex]
Hence in general we say:
[tex]C_t=3\times 2^t[/tex]
Hence,
[tex]3\times 2^t=1536\\\\2^t=\dfrac{1536}{3}\\\\2^t=512\\\\2^t=2^9\\\\t=9[/tex]
Hence, option: D is true.
