D) [tex]y=\frac{2}{3}x+\frac{3}{2}[/tex]

Step-by-step explanation:

The given equations are in the form;

[tex]y=mx+b[/tex]

We  can observe from the graph that the line is sloping forward.

This means that the slope must be positive.

[tex]\implies m=\frac{2}{3}[/tex]

Also the y-intercept is positive

This implies that;

[tex]b=\frac{3}{2}[/tex]

Hence the equation is [tex]y=\frac{2}{3}x+\frac{3}{2}[/tex]

Step-by-step explanation:

The odd number whose a factor is the number 3 is  a positive odd multiple of 3:

3, 9, 15, 21, 27, 33, 39, 45, 51, 57, ...

The answer is:

The third option:

2.7 times as much.

To calculate how many more juice will the new can hold, we need to calculate the old can volume to the new can volume.

So, calculating we have:

Old can:

Since the cans have a right cylinder shape, we can calculate their volume using the following formula:

[tex]Volume_{RightCylinder}=Volume_{Can}=\pi r^{2} h[/tex]

Where,

[tex]r=radius=\frac{diameter}{2}\\h=height[/tex]

We are given the old can dimensions:

[tex]radius=\frac{5.2cm}{2}=2.6cm\\\\height=9.4cm[/tex]

So, calculating the volume, we have:

[tex]Volume_{Can}=\pi *2.6cm^{2} *9.4cm=199.7cm^{3}[/tex]

We have that the volume of the old can is:

[tex]Volume_{Can}=199.7cm^{2}[/tex]

New can:

We are given the new can dimensions, the diameter is increased but the height is the same, so:

[tex]radius=\frac{8.5cm}{2}=4.25cm\\\\height=9.4cm[/tex]

Calculating we have:

[tex]Volume_{Can}=\pi *4.25cm^{2} *9.4cm=533.40cm^{3}[/tex]

Now, dividing the volume of the new can by the old can volume to know how many times more juice will the new can hold, we have:

[tex]\frac{533.4cm^{3} }{199.7cm^{3}}=2.67=2.7[/tex]

Hence, we have that the new can hold 2.7 more juice than the old can, so, the answer is the third option:

2.7 times as much.

Answer:

The father did more.

13/28 needs to be mowed which is 0.4643 of the lawn needs to be mowed.

Step-by-step explanation:

The best way to compare the two is to change them to decimals. That will at least answer who mowed the most.

Father: 2/7 = 0.2857

Son: 1/4 = 0.25

Since the father mowed 2/7 of the lawn, he mowed the most.

You can use the decimals to get the second part.

Together they did 0.25 + 0.2857 = 0.5357

The amount of the lawn left is 1 - 0.5357 = 0.4643

================

If you must have this in fractions then

1/4 + 2/7 = 7/28 + 2*4/28 = 7/28 + 8/28 = 15/28

15/28 = 0.5357 which is just what we got above.

Amount left to do = 1- 15/28 = 13/28

13/28 = 0.4643 which is what we got about.

Answer:

684

Step-by-step explanation:

A=a+b

2h=26+46

2·19=684

Answer:

684 m²

Step-by-step explanation:

The area (A) of a trapezoid is calculated using the formula

A = [tex]\frac{1}{2}[/tex] h (a + b)

where h is the perpendicular height and a, b the parallel bases

here h = 19, a = 46 and b = 26

A = [tex]\frac{1}{2}[/tex] × 19 × (46 + 26)

   = 9.5 × 72 = 684 m²

Answer:

a = 30

b = 40

C

Step-by-step explanation:

This requires that you use a proportion.

a / (a + 15) = 40 / 60

The small triangle's sides are in proportion to the large triangles sides.

Reduce the right. Divide top and bottom by 20

a/(a + 15) = 40/20 // 60/20

a/(a + 15) = 2/3                    

Cross multiply

3a = 2(a + 15)            Remove the brackets on the right.

3a = 2a + 30

Subtract 2a from both sides

3a-2a = 30

a = 30

Find B

b is done exactly the same way.

b/(b+20) = 2/3

3b = 2b + 40

3b - 2b = 40

b = 40

Distance around Pie = Pi*Diameter

Final answer:

The circumference of a 10-inch diameter cherry pie, using the value 3.1 for Pi, is 31 inches, which is the distance around the pie.

Explanation:

The distance around a circle is known as the circumference. To calculate the circumference of a 10-inch diameter cherry pie, we will use the relationship between the diameter and circumference, which involves Pi (π). The formula for the circumference C is C = π × d, where d is the diameter.

Using 3.1 as the approximate value for π, and with a diameter of 10 inches, we can calculate the circumference as follows:

C = π × d = 3.1 × 10 = 31 inches.

Therefore, the distance around a 10-inch cherry pie from Betsy's Bakery is approximately 31 inches.

Answer= .2 probability

Explanation: Since there is a total of 10 marbles, and 2 are red, you would divide the red marbles (2) out of the total marbles (10) which would get u .2. Since it’s asking for probability, we would keep .2 a decimal.

The probability of randomly picking a red marble from the bag is 2 out of 10, or 0.2 when expressed as a decimal, which equates to a 20% chance.

The subject of the question you asked is mathematics, specifically probability. In order to calculate the probability of an event happening, you divide the number of successful outcomes by the total number of outcomes. In this case, the successful outcome would be picking a red marble.

The total number of marbles in the bag is 5 (green) + 3 (blue) + 2 (red) = 10. The successful outcomes are 2 (the red marbles). Therefore, the probability of picking a red marble is 2/10 or 0.2.

To put this as a percentage, you multiply by 100, so the probability is 20%. This means that if you pick a marble out at random, there is a 20% chance that it will be red. This is assuming that after each pick, you put the marble back in the bag, also known as picking 'with replacement'.

Experimental : [tex]\frac{14}{25}[/tex] or 56%

Theoretical : [tex]\frac{1}{2}[/tex] or 50%

2.

22 customers

Step-by-step explanation:

Theoretical is how many times you'd expect it to land. So for coin flipping it would be either heads or tails. The probability it would land on heads would be 50% because it's either one or the other.

Experimental is how many times you actually landed it. You flipped a coin and it landed on heads 28 times, so you can put that over 50.

Since [tex]\frac{28}{50}[/tex] can be simplified to [tex]\frac{14}{25}[/tex] or 56%, that is the experimental probability.

For the second variation, we can assume that it is direct variation.

[tex]y=kx[/tex]

When [tex]y[/tex] increases, [tex]x[/tex] increases.

Let's solve for [tex]k[/tex].

[tex]11=50k \\ \\ k=\frac{11}{50}[/tex]

We can plug that in to the second equation since we already know how many customers there will be.

Answer:

The desired equation is y = (-8/3)x + 3.

Step-by-step explanation:

There's no one general form; several different forms apply here.

Seeing that the y-intercept is (0, 3) and that another point on the line is (3, -5), I'd use the slope-intercept form here:  y = mx + b

As we move from the first point to the second, x increases by 3 and y decreases by 8.  Thus, the slope of the line through the two points is

m = rise / run = -8/3.  As before, the y-intercept is (0, 3), so b = 3.

The desired equation is y = (-8/3)x + 3.

The answer is:

The first option:

[tex]3x+y-3=0[/tex]

To find which is the equation of the line shown, we need to find  a line that intercepts the y-axis at 3 and the x-axis and 1.

So,  discarding we have:

[tex]3x+y-3=0[/tex]

Making "x" equal to 0 in order to find the y-axis intercept, we have:

[tex]3(0)+y-3=0[/tex]

[tex]y=3[/tex]

Making "y" equal to 0 in order to find the x-axis intercept, we have:

[tex]3x+0-3=0[/tex]

[tex]3x=3[/tex]

[tex]x=\frac{3}{3}=1[/tex]

So, we have found that the x-axis and y-axis intercept of the equation, are the shown in the picture.

The interception points of the equation and the line are:

For x-axis:

[tex](1,0)[/tex]

For y-axis:

[tex](0,3)[/tex]

Hence, the answer is the first option.

[tex]3x+y-3=0[/tex]

Answer:

(-a, -b)

Step-by-step explanation:

It's a square that has both X-axis and Y-axis as lines of symmetry.  We can then conclude the center of the square is at the origin (0,0).

It doesn't matter if the square is straight up (both axis being the mid-points symmetry lines, and one corner in each quadrant) or if it is turned (both axis being the diagonals and the corners are on the axis), in any case if a summit (corner) is defined as (a,b), the opposite corner will be at (-a,-b).

(a,b) could be (2,2), then opposite would be (-2,-2).

(a,b) could be (3,0), then the opposite would be (-3,0).

Answer:

The domain of the function in the correct set notation is {x|x∈R x≠-3}.

The domain of a function is the set of all possible inputs that the function can have.

The function is given to be f(x)=1 /(2x+6).

Here, we can see that the function would become not be defined if the denominator becomes zero.

Therefore, the domain should not contain the values which make it not defined.

The value of x for which it becomes zero can be determined below:

2x+6=0

2x=-6

x=-3

Therefore, the domain must contain all values of real numbers except -3.

The domain of the function is found. The domain of the function is the set of all real numbers except -3. It can be written as {x|x∈R x≠-3}.

Therefore, we have found the domain of the function in the correct set notation is {x|x∈R x≠-3}.
