Which linear inequality is represented by the graph?

Final answer:

The next time a museum tour and video both start at the same time after 10:00 a.m. is at 11:00 a.m., as that is when their intervals (every 20 minutes for tours and every 15 minutes for videos) have their Least Common Multiple.

Explanation:

The question is about finding the next time a museum tour and a video both start at the same time after 10:00 a.m. The tours start every 20 minutes and the videos start every 15 minutes. To find the next common start time, we need to calculate the Least Common Multiple (LCM) of 20 and 15 which is the smallest number that both 20 and 15 can divide into without leaving a remainder.

Multiples of 20 are 20, 40, 60, 80, 100, ...

Multiples of 15 are 15, 30, 45, 60, 75, ...

The first common multiple of the two intervals is 60 minutes. Therefore, since both the tour and the video start at the same time (10:00 a.m.), the next time they will both start together will be 60 minutes later, which is at 11:00 a.m.

y = 7x +3 slope is rise over run with would be 7/1 and y intercept is 3

The equation in the slope-intercept form is y=7x+3.

Given:

Find:

Solution:

We will use y = mx+b where m = slope and b = y-intercept.

y = mx+b

Now, putting (1,10) in the place of x and y and slope as 7, we get;

10 = 7*1 + b

b = 10-7

b=3

So, the y-intercept is 3.

Now, putting the y-intercept in the slope-intercept equation, we get;

y = 7x+3

Hence, the equation in slope-intercept form is y=7x+3.

Answer:

Solution is (1,7).

Step-by-step explanation:

We need to find the solution of the system of following equations.

y= 5x + 2        eq(1)

3x = -y +10      eq(2)

We will solve the equations using Substitution method to find the values of x and y

we put value of y from eq (1) into eq (2), The eq(2) will be:

3x = - (5x + 2) + 10

3x = -5x -2 +10

3x+5x = -2+10

8x = 8

x= 1

Now, putting value of z in eq(1) to find value of y

y = 5x +2

y = 5(1) + 2

y = 5+2

y = 7

So, Solution is (1,7).

Answer:

After 11 years the value of the investment reaches $1500.00

.

Step-by-step explanation:

The formula used for finding time (when the value reaches certain amount) is:

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

where A= Future VAlue

P= Principal Value

r= rate of interest (in decimal)

n= no of times investment is compounded

t= time

Putting the values given and finding Time t,

A= $1500

P= $1200

r= 2% or 0.02

n= 4 (compound quarterly)

[tex]A= P(1+\frac{r}{n})^{nt}[/tex]

[tex]1500= 1200(1+\frac{0.02}{4})^{4t}[/tex]

Dividing both sides by 1200 and solving 0.02/4 = 0.005

[tex]1.25= (1+0.005)^{4t}[/tex]

[tex]1.25= (1.005)^{4t}[/tex]

Since t is in power we take the logarithm ln on both sides.

The rule of logarithm says that the exponent can be multiplied with the base when taking log

[tex]\ln1.25=ln( 1.005)^{4t}\\\ln1.25=4t * ln( 1.005)\\0.22 = 4t * 0.005\\Solving\,\,\\\frac{0.22}{4*0.005} = t\\=> t= 11\, years[/tex]

the greatest number of bowls of ice cream Kia can serve is 64.

The student wishes to determine the greatest number of bowls of ice cream that can be served given certain quantities of ice cream and serving sizes. To solve this, we first calculate the total amount of ice cream by adding the quantities of vanilla and chocolate ice cream. Kia bought 2 cartons of vanilla and 6 cartons of chocolate, each containing 32 ounces. Thus, the total amount of ice cream is (2 + 6) × 32 ounces. Each bowl served contains 4 ounces of ice cream. To find the number of bowls, we divide the total ounces of ice cream by the ounces per bowl. This yields (8 × 32) ÷ 4, which calculates to 64 bowls. Therefore, the greatest number of bowls of ice cream Kia can serve is 64.

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.

A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.  

The python is 2.6 pi (2.6π) meters long.

What is the radius r of the circle that the python forms?

Now we have: C = π d, or (with d = 2 r):  C = 2 π r.

Changing that around: r = C / 2 π

So with our value of C = 2.6π meters, that gives us:

r = 2.6π/2π = 2.6/2, so r = 1.3 meters  

Answer:

The answer is 1.3

ANSWER

[tex]x = \frac{5}{4} - \frac{ \sqrt{ 17} }{4} [/tex]

or

[tex]x = \frac{5}{4} + \frac{ \sqrt{ 17} }{4} [/tex]

EXPLANATION

The given equation is:

[tex]2 {x}^{2} - 5x + 1= 0[/tex]

Comparing this to

[tex]a {x}^{2} + bx + c = 0[/tex]

we have a=2, b=-5, c=1

The quadratic formula is given by

[tex]x = \frac{ - b \pm \sqrt{ {b}^{2} - 4ac} }{2a} [/tex]

We substitute the values to get,

[tex]x = \frac{ - - 5 \pm \sqrt{ {( - 5)}^{2} - 4(1)(2)} }{2(2)} [/tex]

[tex]x = \frac{ 5 \pm \sqrt{ 17} }{4} [/tex]

[tex]x = \frac{5}{4} - \frac{ \sqrt{ 17} }{4} [/tex]

or

[tex]x = \frac{5}{4} + \frac{ \sqrt{ 17} }{4} [/tex]

[tex] {x}^{2} + {y}^{2} = 10[/tex]

EXPLANATION

The center of the circle is (0,0).

The circle passes through (-1,-3).

The radius can be obtained using the distance formula:

[tex]r = \sqrt{(0 - 1)^{2} + {(0 - - 3)}^{2} } = \sqrt{10} [/tex]

The equation is given as:

[tex]( {x - h)}^{2} + ( {y - k)}^{2}= {r}^{2} [/tex]

Where (h,k) is the center and r is the radius.

This implies that;

[tex]( {x - 0)}^{2} + ( {y - 0)}^{2}= {( \sqrt{10)} }^{2} [/tex]

[tex] {x}^{2} + {y}^{2} = 10[/tex]

Where:

P: They are the profits

p: It is the sale price

c: It's the cost

We have Malik buy the tires at $ 45, then the cost is $ 45. As he sold them at $ 65 then the sale price is $ 65.

We have:

Answer:

-109

Step-by-step explanation:

Arithmetic sequence formula:

an = a1  + d(n - 1) where d = -4 and a1 = 19

so

a(33) = 19 - 4(33-1)

a(33) = 19  - 4(32)

a(33) = 19 - 128

a(33) = -109

The missing term : -109

Answer:

-109

Step-by-step explanation:

As x changes from 1 to 2, 2 to 3, and 3 to 4, each change in x is 1. The  corresponding changes in y from 19 to 15, from 15 to 11, and from 11 to 7, are each a change of -4 in y. For each change of 1 in x, the corresponding change in y is -4. From 4 to 33 in x, the change is 33 - 4 = 29. The corresponding change in y is 29 * (-4) = -116.

7 + (-116) = -109

Peter will be 75 years old in 47 years.

Answer:

In 47 years Peter will be 75 years old

Step-by-step explanation:

If Peter will be 54 years old in 26 years then subtract 26 from 54

54-26=28

This means that Peter is 28 right now, if you want to double check that work then add 26 to 28 implying that in 26 years Peter with be 54 years old

28+26=54

This shows that your calculations are correct! Now you have to figure out how many years from now will Peter be when he turns 75 years old, so you subtract his current age which is 28 from 75

75-28=47

Now to double check this add 47 to his current age which is 28

28+47= 75

This shows that your calculations are correct and it will take 47 years for Peter to be 75 years old!

For this case we have that the equation of the border line of the region is given by:

[tex]y = -2x-3[/tex]

To know the sign of inequality, we must evaluate a point that belongs to the region and verify if it is fulfilled.

As the border line is dotted, we discard options A and C.

Then, we evaluate the point (-2, -4)

Option B: [tex]y <-2x-3[/tex]

[tex]-4 <-2 (-2) -3\\-4 <4-3\\-3 <1[/tex]

Our orginal expression is: (x + 4)². In this expression, A can be written as x, B represents for 4, that leads to our answer:

(x + 4)² = x² + 2 . 4x + 4² = x² + 8x + 16

The correct answer will be D

The width is

[tex]w = 4 \frac{1}{2} in[/tex]

and the height is

[tex]h = 3\frac{1}{2} in[/tex]

We substitute the values into the formula to obtain;

[tex]Volume =8 \times 4 \frac{1}{2} \times 3 \frac{1}{2} [/tex]

[tex]Volume =8 \times 4.5 \times 3.5[/tex]

[tex]Volume =126 {in}^{3} [/tex]

Answer:

The correct answer is option D.  126 in³

Step-by-step explanation:

Formula:-

Volume of cuboid - lbh

l - Length of cuboid

b - Breadth of cuboid

h - Height of cuboid

To find the volume of prism

Here rectangular prism is like a cuboid.

l = 8 in, b = 4 1/2 = 9/2 and h = 3 1/2 = 7/2

Volume = lbh

     = 8 * 9/2 * 7/2 = 126 in³

Therefore the correct answer is option D.  126 in³
