Answer:

(4,5)

Step-by-step explanation:

We are to find the circumcenter of triangle EFG with vertices

E(2,6), F(2,4), and G(6,4)

Let S(x,y) be the circum center.  Then this point is equidistance from E, F and

G

i.e. [tex]ES=FS=GS\\ES^2 =FS^2 =GS^2[/tex]

[tex](x-2)^2+(y-6)^2 =(x-2)^2+(y-4)^2 =(x-6)^2+(y-4)^2 \\i.e. x^2-4x+4+y^2-12y+36 = x^2-4x+4+y^2-8y+16 = x^2-12x+36+y^2-8y+16 \\4y = 20: y =5\\8x=32\\x=4[/tex]

Thus circumcenter is (4,5)

Answer:

[tex]f(x) = {x}^{2} - 15x + 26[/tex]

Step-by-step explanation:

Assuming we want to write a quadratic function with intercepts x=13 and x=2.

Then we can work backwards.

This means that:

x-13=0 and x-2=0

The factored form of this quadratic function becomes:

[tex]f(x) = (x - 13)(x - 2)[/tex]

We expand to get:

[tex]f(x) = {x}^{2} - 2x - 13x + 26[/tex]

We simplify to obtain:

[tex]f(x) = {x}^{2} - 15x + 26[/tex]

Answer:

See photo

Step-by-step explanation:

The line is in slope-intercept form which looks like y = mx + b.

"x" and "y" represent points on the line.

"m" is the slope (how steep the line is) and if the line goes up (+) or down (-).

"b" is the y-intercept, which is where the graph hits the y-axis.

Take information from the equation y=-2x+6. Use the slope and the y-intercept to graph to line.

m = -2  =  [tex]-\frac{2}{1}[/tex]   (Fraction form).

b = 6

Plot a point at the y-intercept on the y-axis

If the y-intercept is 6, so you plot the point at (0, 6). (The y-intercept occurs when x = 0).

Find another point

Count the number of rise and run from the y-intercept.

Remember the slope is [tex]\frac{rise}{run}[/tex]

Run is the number of squares moving right. Rise is the number of squares moving up (if positive) or down (if negative).

Since the slope is -2/1, move two squares down and one square to the right to find another point on the line.

Connect the points

You only need two points to make a line. If you want the line to be longer, you can extend it with a ruler.

Other formatting rules

Remember to add arrows at the ends of the x and y axis.

Also, add arrows to the ends of the the line that you graphed.

Most teachers ask you to label the line with the equation.

Step-by-step explanation:

The quotient of 987 divided by 47 is found to be 21 using estimation and step-by-step long division.

The question asks to find 987 divided by 47 using an efficient strategy and show the work. To solve this, we can perform long division.

The final answer is 21 because 47 goes into 987 exactly 21 times. The most efficient strategy here was to use estimation and subtraction to find the quotient step-by-step.

Option B: 5.25 is the length of XZ

Explanation:

The triangles PQR and XYZ are similar.

To determine the length of XZ, let us use the similarity theorem.

The theorem states that, "if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar".

Thus,

[tex]\frac{QR}{YZ} =\frac{PR}{XZ}[/tex]

Let us substitute the values from the diagram, we have,

[tex]\frac{4}{3} =\frac{7}{XZ}[/tex]

Multiplying both sides by 3, we get,

[tex]4 =\frac{21}{XZ}[/tex]

Thus,

[tex]XZ =\frac{21}{4}=5.25[/tex]

Thus, the length of XZ is 5.25

Hence, Option B is the correct answer.

Answer: 95 sold



Step-by-step explanation:

995 horses and cows - 510 horses and 390 cows left = 95 sold

Answer:

95

Step-by-step explanation:

add 510 + 390 to find out the total number of horses and cows he has left. this equals 900

then you subtract the total of horses and cows he started with by what he has left to find out how many he sold

995-900=95

Answer: 1.9

Step-by-step explanation:

because you keep adding 1.9 to get your result

Answer:

11.1

Step-by-step explanation:

3.9 - 1.5 = 2.4

if you add 2.4 to one of the numbers in the sequence it will be the next number.

1.5 + 2.4 = 3.9

3.9 + 2.4 = 6.3

6.3 + 2.4 = 8.7

if this is the case then 8.7 + 2.4 = 11.1

Answer: 90 tarts

Step by Step: 150/5 = 30

30 multiplied times 3 = 90

Final answer:

Jake initially had 750 tarts, sold 450 of them, and had 150 tarts remaining after giving some to his friends.

Explanation:

Jake initially had a total number of tarts. He sold 3/5 of them and then gave 1/4 of the remainder to his friends. If he had 150 tarts left, we need to calculate the number he sold. Let's denote the total number of tarts as T. After selling 3/5 of T, Jake would have 2/5T left. Then, he gives away 1/4 of 2/5T, which means he's giving away 1/4 * 2/5T = 1/10T. So, he is left with 2/5T - 1/10T = 1/5T. We know that 1/5T equals 150, so T equals 150 * 5 = 750. Jake sold 3/5 of these, which is 3/5 * 750 = 450 tarts.

Answer:

Step-by-step explanation:

5 pinks =9 greens

x pinks = 27 greens

Cross multiply

5pinks × 27 greens =x pinks × 9greens

Divide both side by 9green

5 pinks × 27 greens / 9greens =x pinks

Then green cancel greens

x pink = 15 pinks

Then, 27 greens implies 15 pinks

It takes about 14.55 years for quadruple your money

Solution:

Given that,

At 10 percent interest, how long does it take to quadruple your money

Rule of 144:

The Rule of 144 will tell you how long it will take an investment to quadruple

Here,

Rate of interest = 10 %

Therefore, number of years to quadruple your money is obtained by dividing 144 by 10

Rule of 144 Formula:

[tex]N = \frac{144}{R}[/tex]

Where:

N = Number of many years times.

144 = Is the constant variable.

R = Rate of interest.

[tex]\rightarrow N = \frac{144}{10} = 14.4[/tex]

Thus it takes about 14.4 years for quadruple your money.

Another method:

If initial amount is $ 1 and it if quadruples it should be $ 4

We have to find the number of years if rate of interest is 10 %

Let "n" be the number of years

Then we can say,

[tex]Amount = Principal(1+\frac{R}{100})^n[/tex]

[tex]4 = 1(1+\frac{10}{100})^n[/tex]

[tex]4 = 1(1+0.1)^n\\\\4= 1(1.1)^n\\\\4 = 1.1^n\\\\We\ know\ that,\\\\(1.1)^{14.55} = 1.1^n\\\\We\ know\ that\\\\If\ a^m = a^n\ then\ m = n\\\\Therefore,\\\\14.55 = n\\\\n = 14.55[/tex]

Thus Option D 14.55 years is correct

Answer:jennie has 536 songs and diamond has 359

Step-by-step explanation:

Answer:

For plato users: Option C.

Step-by-step explanation:

Answer: x = 995

Step-by-step explanation:

In this equation our log doesn't have a base so it is given the default base of 10. This makes our equation really.

[tex]log_{10}(x+3) + log_{10}(2) = 3[/tex]

Now we put every equation as the exponent of our base 10 looks like this:

[tex]10^{log_{10} (x+3)} + 10^{log_{10} (2)} = 10^{3}[/tex]

Now we cancel out the log base 10 and the 10. We are left with:

(x+3) + (2) = 10^3

Lastly solve for x

x + 5 = 1000

x = 995

Answer:

Step-by-step explanation:

When you talk about "unit price," you need to define the unit of interest. Unit prices on grocery store shelves don't always use the same unit, even for like items. Here it might be convenient to use any of the following as the "unit":

The "unit price" is computed as ...

  unit price = (price for some number of units)/(the number of units)

The "number of units" may be larger, smaller, or equal to 1.

Then the price per cup (8 ounces) would be ...

  unit price = (price for 15 oz)/(15/8 cups) = ($2.79)(8/15)

  = $1.488 per cup

__

The price per ounce would be ...

  unit price = ($2.79)/(15 oz) = $0.186/oz

__

We assume that the unit of interest is probably 1 ounce, but it could be something else. Your grader may expect the value to be rounded to the nearest cent, $0.19 per ounce.

The unit price of shampoo is approximately $0.186 per ounce.

To find the unit price of shampoo, divide the cost of the bottle by the number of ounces it contains. In this case, the cost is $2.79 and the bottle is 15 ounces. So, the unit price can be calculated as $2.79 divided by 15 ounces, which gives us approximately $0.186 unit price per ounce.
