Given

[tex]Points: (x_7 - y_i),(4,8)[/tex]

Required

Is the distance between them [tex]\sqrt{(x_7 - 8)^2 + (y_1 - 4)^2}[/tex]

Given that there are two points, the distance between them is calculated using

Distance = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex]

In this case;

[tex](x_1,y_1)= (x_7 - y_i)\\(x_2,y_2) =(4,8)[/tex]

Substitute these in the given formula

Distance = [tex]\sqrt{(4- x_7)^2 + (8 - y_1)^2}[/tex]

Comparing this with the given formula, both are not the same;

Hence, the formula is false and the correct formula is of the form [tex]\sqrt{(4- x_7)^2 + (8 - y_1)^2}[/tex]

Answer:

10.7 m

Step-by-step explanation:

C = 2(pi)r = 2 * 3.14159 * 1.7 m

C = 10.7 m

Answer:

About 10.7m.

Step-by-step explanation:

Formula for Circumference: [tex]C=2\pi r[/tex]

We are given the radius of 1.7m.

Using 3.14 for pi:

[tex]C=2*3.14*1.7\\\\C=6.28*1.7\\\\\boxed{C=10.676}[/tex]

10.676 ≈ 10.7

The circumference of the circle should be about 10.7m.

Answer: 16 more seniors than juniors stay at the after-school program

Step-by-step explanation:

50 * 60% = 50 * .6 = 30

30 * 80% = 30 * .8 = 24

50 - 30 = 20

20 juniors and 30 seniors in total

$11.40

Step-by-step explanation:

$38 for 2 people to go to the movie theater.

38/2=19

$19 for each person to go to the movie theater.

40% of the money is for snacks, the movie ticket must be 60% of the money.

19×60%

19×60/100=11.4

The cost of each movie ticket is $11.40

Answer:

$11.4

Step-by-step explanation:

Total Cost = $38

Snacks:

=> [tex]\frac{40}{100}* 38[/tex]

=> $15.2

Left for 2 tickets:

=> $38-$15.2

=> $22.8

For 1 ticket:

=> $22.8/2

=> $11.4

Answer:

x = 18

Step-by-step explanation:

start with your equation: 1/3x + 4 = 10

first subtract 4 from both sides of the equal sign

now you have: 1/3x = 6

then divide by 1/3 on both sides

which gives you...

x = 18

you can check it by replacing x with 18.

hope this helps!

Answer:

[tex]x=18[/tex]

Step-by-step explanation:

[tex]\frac{1}{3}x+4=10[/tex]

Subtract 4 from both sides

[tex]\frac{1}{3}x=6[/tex]

Multiply both sides by 3

[tex]x=18[/tex]

Answer:

x=15,y=3

Step-by-step explanation:

x-y=12

x+y=18

now,x=12+y

substituting in x+y=18

(12+y)+y=18

12+2y=18

2y=18-12

2y=6

y=6/2

y=3

now,x=12+y

so,x=12+3

x=15

Shannon rounded $57.25 to $60 and 28 pounds to 20 before dividing

Step-by-step explanation:

When she rounded $57.25 to $60 and 28 pounds to 20, the result she got was 60/20=$3. The issue was this is that she rounded up for the dividend and rounded down the divisor, leading to a much bigger estimate than the real answer. Hope this helps!

The error she did was Shannon rounded $57.25 to $60 and 28 pounds to 20 before dividing , Option B is the answer.

Error is the calculation mistake done while doing mathematical operations.

It is given that

Shannon paid $57.25 for 28 pounds of potatoes.

She paid $57.25 /28 = $ 2.045 for 1 pound of potato

She estimated the cost per pound to be $3.00

which means $0.955 more than the actual cost

The error she did was Shannon rounded $57.25 to $60 and 28 pounds to 20 before dividing.

$60/20 = $3

Therefore Option B is the answer.

First you must have a common denominator.

Change 1/2 to 4/8

(1/2 = 4/8)

Second:

5/8 is greater than 1/4  (aka 1/2)

so

Answer:

65

Step-by-step explanation:

The sum of the angles in a triangle is 180. In a right triangle, there is one 90 degree angle. If the second angle is 25, and 90+25+the last angle must add up to 180, simple math can find the value of the last angle.

180-90-25=65

The next term is

Step-by-step explanation:

The sequence is going down by 5 so you divide -250 by 5 and you get -50

Answer:

250

Explanation:

The general term of a geometric sequence has the form:

an= a⋅r^n−1

where a is the initial term and r the common ratio.

In the example: a 1 = 1250 and 3 = 50

So: r^2 = ar^2/ar^0 = a^3/a^1 = 50/1250=1/25=1/5^2

Hence: r = ± 1/5

Then: a^2= a⋅ r ^2−1 = 1250⋅(±1/5)= ±250

Answer:

B

Step-by-step explanation:

[tex]\dfrac{x}{3}+\dfrac{x}{7}<2[/tex]

Since the least common multiple of 3 and 7 is 21, multiply both sides by 21:

[tex]7x+3x<42 \\\\10x<42[/tex]

Divide both sides by 10 to isolate x:

[tex]x<\dfrac{42}{10}\\\\\\x<\dfrac{21}{5}[/tex]

Therefore, the correct answer is choice B. Hope this helps!

Answer:

A. Graph A

Step-by-step explanation:

(x-8)(x+5)

First thing you do is put the X's into the parentheticals because it is x^2 meaning there are 2 factors with x's. Then, you wonder what factors of -40 could add to get -3. In this case, they are -8 and 5. -8 times 5 is -40 and -8 +5 is -3. Then, you just add -8 and 5 beside the x's in the parentheticals.

Answer:

= (x - 8)(x + 5)

If it is an equation which just means it is equal to zero e.g. x^2 - 3x - 40 = 0

then we would continue and write our x values!

So assuming it was an equation here is the rest of the working:

x - 8 = 0        x + 5 = 0

x = 8                    x = -5

x = 8, x = -5

Answer:

y = 0.5x + 3

Step-by-step explanation:

First consider the slope of this line. If two points that lie on this line are ( 0, 3 ) - ( which is supposedly the y - intercept ), and ( 2, 4 ) take that change in y / change in x to derive the slope;

[tex]( 0, 3 ), ( 2, 4 )\\\\\\Slope = 3 - 4 / 0 - 2,\\Slope = - 1 / - 2\\Slope = 1 / 2 \\\\Slope = 0.5[/tex]

I did mention earlier that the y - intercept was found to be 3. If that is so, taking the equation in point - slope form, we can tell the equation of the line through the following steps;

[tex]y = mx + b,\\m = slope, \\b = y - intercept\\\\Equation, y = 0.5x + 3[/tex]
