Answer:

[tex]b=5[/tex]

Step-by-step explanation:

The given equation is:

[tex]y=3x+5[/tex]

To find the point where this line intersect the y-axis, we put x=0 into the given equation.

When x=0, we have [tex]y=3(0)+5[/tex].

This implies that; y=5.

The y-intercept is (0,5).

Comparing (0,5) to (0,b), we can conclude that; b=5

The given equation is not in the correct form. Once corrected to y = -3x - 5, it's clear the y-intercept (b) is -5, so the line intersects the y-axis at the point (0, -5).

The equation of a line in the xy-plane is typically written in the form y = mx + b, where m represents the slope and b represents the y-intercept.

The y-intercept is the value of y when x is zero, which means it is the point at which the line crosses the y-axis.

In the case of the equation provided, y + 3x + 5, this equation is not yet in the standard form for the equation of a line. To find the value of b, we need to isolate y. The correct form of the equation should be y = -3x - 5. Here, the y-intercept b is -5. This means that the line intersects the y-axis at the point (0, -5).

The value of x in the expression (5x-15)°, which is the measure of an interior angle of a regular triangle, is 15.

The expression (5x-15)° is given as the measure of one interior angle of a regular triangle. This is a bit complex, as regular triangles, also known as equilateral triangles, only have angles that measure 60° each. Thus, we can set up the equation 5x - 15 = 60.

Solving for x, we get:

So, the value of x that would result in each angle of an regular triangle measuring (5x-15)° is 15.

Answer:

[tex]\dfrac{1}{12}+\dfrac{1}{15}+\dfrac{1}{x}=\dfrac{1}{6}[/tex]

60 hours

Step-by-step explanation:

John - 12 hours

Rick - 15 hours

Molli - x hours

Together - 6 hours

Each of them can paint:

John - [tex]\frac{1}{12}[/tex] of a room per hour

Rick - [tex]\frac{1}{15}[/tex] of a room per hour

Molli - [tex]\frac{1}{x}[/tex] of a room per hour

Together - [tex]\frac{1}{6}[/tex] of a room per hour

So the equation is

[tex]\dfrac{1}{12}+\dfrac{1}{15}+\dfrac{1}{x}=\dfrac{1}{6}[/tex]

Solve this equation:

[tex]\dfrac{1}{x}=\dfrac{1}{6}-\dfrac{1}{12}-\dfrac{1}{15}\\ \\\dfrac{1}{x}=\dfrac{10-5-4}{60}=\dfrac{1}{60}\\ \\x=60[/tex]

Molli can paint the room in 60 hours.

Answer:

Option 4: 0.554

Step-by-step explanation:

As we can see that the intervals and their frequencies are given.

We have to calculate the probability of students' score falling between 70 and 89. It will use the frequency of both intervals 70-79 and 80-89.

So, combined scores of both intervals are:

172+105 = 277

Now to find the probability

= 277/500

=0.554

So option no 4 is the correct answer ..

S_n = n(first term + a_n)/2

n = 15

S_15 = 15(2 + a_n)/2

We need a_n.

a_n = first term + d(n - 1)

a_n = 2 + d(15 - 1)

1. Find d.

2. Plug d into expression to find a_n.

3. After finding a_n, plug back into

S_15 = 15(2 + a_n)/2 to find the sum of the first 15 terms.

Take it from here.

Answer:

72

Step-by-step explanation:

He makes 18/30 passes. We need to see how many passes he can make out 120, so we need to see how many times 30 goes into 120.

120/30=4

So 120 is equivalent to 4 30s. Now to find out how many passes he'd make we multiply 18 by 4.

18*4=72

Answer: 180 ft2

Step-by-step explanation:

The formula for the area of a rectangle is Area = length X width. Since the length is 20 feet and the width is 9 feet , you multiply 20 X 9, which gives you 180 square feet. Hope this helps!

Answer:

The interior volume of the work box is 70 inches³

Step-by-step explanation:

* Lets talk about the volume of the regular solid

- The volume of the solid = area of the base × its height

- If the base of the solid shaped rectangle

∵ The area of the rectangle = Length × width

∴ The volume = Length × width × Height

* Now lets solve the problem

- The work box has three dimensions

# Length = 5 inches

# Width = 3.5 inches

# Height = 4 inches

∴ The work box is shaped a rectangular solid

∴ Its volume = Length × width × height

∵ Length = 5 inches

∵ Width = 3.5 inches

∵ Height = 4 inches

∴ The volume = 5 × 3.5 × 4 = 70 inches³

* The interior volume of the work box is 70 inches³

Answer:

Its 3.5c

Step-by-step explanation:

Let's find the constant of proportionality.

In the proportional relationship between c, the number of cranes, and t, the total time in minutes, one constant of proportionality is the amount of time per crane. It is the number we multiply by the number of cranes to get the total time.

c times ? =t

The constant of proportionality is 3.5 This means we can multiply 3.5 by the number of cranes to get the total time.

Now, let's represent that as an equation.

total time= time per crane X number of cranes

total time

t

​

time per crane×number of cranes

3.5c

​

One correct equation is:

t= 3.5c

Answer:

t = 3.5c

Step-by-step explanation:

This represents a proportional relationship because it is linear (he is folding at a constant rate) and passes through the origin (it would take him 0 minutes to fold 0 cranes). The formula for a proportional relationship is y = kx, where k is the constant of proportionality.

To find k, divide the dependent variable by its corresponding indepent variable. In this example, the amount of minutes is the dependent variable and the amount of cranes is the independent variable.

Using the first row of the table, we get  [tex]k = \frac{17.5}{5} = 3.5[/tex].

Just to confirm our answer, let's try the other values given in the table:

[tex]k = \frac{28}{8} = 3.5\\k = \frac{42}{12} = 3.5[/tex]

So, we get that it takes Terrence 3.5 minutes to make one crane, so t = 3.5c

Answer: 1 term

Reason:Polynomials are classified according to their number of terms. 4x3 +3y + 3x2 has three terms, -12zy has 1 term, and 15 - x2 has two terms. As already mentioned, apolynomial with 1 term is a monomial. A polynomial with twoterms is a binomial, and apolynomial with three terms is a trinomial.

Answer:

One Term

Step-by-step explanation:

The answer is one term, because there are no "+" or "-" happening. A term is only separated by the addition/subtraction sign, and since there are neither plus or minus, there is only one term.

Answer:

5/6

Step-by-step explanation:

Step 1: Find Alicia's share of the gift. To do this, all you have to do is multiply 120 by 2/5, which is 40%. 120 * 40% (0.4) is 48. Alicia's share is $48.

Step 2: Find Jason's share of the gift. In this case, divide 120 by 3. 120/3 is 40. Jason's share is $40.

Step 3: Express the numbers as a fraction and simplify it. 40/48 is the common fraction. Find the GCF of 40 and 48. When you solve for it, the GCF is 8. Divide both the numerator and the denominator by 8. 40/8 is 5/ 48/8 is 6. There. 5/6 is our simplified fraction, which is the ratio.

Answer:

Andrew's height is [tex]1\frac{5}{8}[/tex] meters

Explanation:

We know that John's height is [tex]1\frac{3}{4}[/tex] meters

We are given that:

John is [tex]\frac{1}{8}[/tex] meters shorter than Paul

This means that:

Paul's height = John's height + [tex]\frac{1}{8}[/tex]

Paul's height = [tex]1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8}[/tex] meter

We are given that:

Paul is 0.25 meters taller than Andrew

This means that:

Andrew's height = Paul's height - 0.25

Andrew's height = [tex]1\frac{7}{8} - 0.25 = 1\frac{5}{8}[/tex] meters

Hope this helps :)

Step-by-step explanation:

Answer:

P(A) x P(B)

Step-by-step explanation:

If im wrong, im so sorry

P(A | B) is found using the formula P(A AND B) / P(B), which in the context of rolling a dice and looking at events such as rolling a prime number (A) given rolling an odd number (B) would imply looking at the shared outcomes of both events and then calculating the probability.

The Venn diagram question is asking for P(A | B), which is the probability of event A happening given that event B has happened.

The multiplication rule is an important tool to solve this problem, stating that if A and B are independent events, then P(A AND B) = P(A) × P(B).

However, the calculation of P(A | B) is different.

To find P(A | B), which is read as "the probability of A given B," you use the formula P(A AND B) / P(B).

If we consider that A is the event of rolling a prime number (e.g., numbers 2, 3, 5 in a dice) and B is the event of rolling an odd number (e.g., numbers 1, 3, 5), then the outcomes that are both prime and odd (A AND B) would be {3, 5}.

If event B has already occurred (rolling an odd number), we adjust the sample space accordingly and calculate the probability of A within this new space.

Option B

Answer:

b = 2 or b = 7

Step-by-step explanation:

b/(b-7) - 2/b = 7/ (b-7)

b * b - 2(b - 7) = 7 * b

b^2 - 2b + 14 = 7b

b^2 - 9b + 14 = 0

(b - 2)(b - 7) = 0

b - 2 = 0; b = 2

b - 7 = 0; b = 7

Answer

b = 2 or b = 7

Answer:

15 hours and 10 min

Step-by-step explanation:

6 1/2 hours on Monday

8 2/3 hours on Tuesday

You have to make the fractions equal to each other so you would have

1/2 x 3 = 3/6

2/3 x 2 = 4/6

Then add them together to get

7/6 or 1 1/6

6+8 = 14

Then add the 1 to 14 to get 15

1/6 of an hour is 10 minutes

Therefore your answer would be 15 hours and 10 minutes

The reflection that will produce that image would be a reflection across the y-axis

The line segment should be reflected across the y-axis to obtain the desired image with endpoints at (4, -6) and (6, 4).

To find the reflection of the line segment with endpoints (-4,-6) and (-6,4) that will produce an image with endpoints at (4,-6) and (6,4), we can use the formula for reflecting a point in the x-axis or y-axis. The reflection of a point (x, y) in the x-axis is (x, -y) and the reflection of a point (x, y) in the y-axis is (-x, y). Applying these formulas to the given endpoints, we can determine that the reflection in the y-axis will produce the desired image. So, the line segment will be reflected across the y-axis to obtain the image with endpoints at (4, -6) and (6, 4).
