HELP ME!!! I’LL GIVE BRAINLIEST!!! PLEASE

Given:

The two points are (-1,2) and (5,-2).

To find:

The distance between the given points.

Solution:

Distance formula:

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

Using the distance formula, the distance between the given points is

[tex]d=\sqrt{(5-(-1))^2+(-2-2)^2}[/tex]

[tex]d=\sqrt{(5+1)^2+(-4)^2}[/tex]

[tex]d=\sqrt{(6)^2+16}[/tex]

[tex]d=\sqrt{36+16}[/tex]

On further simplification, we get

[tex]d=\sqrt{52}[/tex]

[tex]d=7.2111[/tex]

[tex]d\approx 7.21[/tex]

Therefore, the the distance between the given points is about 7.21 units.

157.05

Step-by-step explanation:

i dont know explain your?

Answer:

You were off by 80%

Step-by-step explanation:

Answer:

x = -2

y = 6

Step-by-step explanation:

i multiplied the 1st equation by 3 and the 2nd by 5 to get the y-terms to zero out

   12x + 15y = 66

+  35x - 15y = -160

   47x = -94

x = -94/47

x = -2

substitute -2 for 'x' to solve for 'y':

4(-2) + 5y = 22

-8 + 5y = 22

5y = 30

y = 6

Answer:

The metal worker should use 10 kgs of 25% copper alloy and 40kgs  of 70% copper alloy to make it

Step-by-step explanation:

Answer:

The metalworker should use 10 kgs of 25% copper  and 40 kgs of 70% alloy to make it.

Answer:

Step-by-step explanation:

A+B+C = 90°

A ≤ B ≤ C

C = 3A

B = 2A

A+B+C = A + 2A + 3A = 6A = 90°

A = 15°

B = 2A = 30°

C = 3A = 45°

Answer:Your answer would be F

Step-by-step explanation:

Answer:

1. Yes

2. 112 ounces

Step-by-step explanation:

To answer this question, we should first convert the amount of pounds Rick's cat weighs into ounces, so that both measurements are in the same unit. Since 1 pound is the same as 16 ounces, we can multiply 7 pounds by 16 ounces:

7 * 16 = 112

So, Rick's cat weighs 112 ounces, which is more than his neighbor's puppy, which only weighs 103 ounces. so for the first question, the answer is:

Yes, Rick's cat weighs more than the puppy.

And the second answer is:

Rick's cat weighs 112 ounces.

Hope this helps :)

Answer:

9.20

Step-by-step explanation:

9.12 because 6 rounded to nearest hundredth is 10 and that is a whole number. You also already know that 16 is a higher number than ten so it would be rounded to 20 or in this case 2. Hope this helps :)

Answer:

Its actually only 8 points but its ok.

Tell me if I got it wrong plz!!

if there was a graph I would be able to help you but you have on here how many distinct Circles of radius 2 units are on the coordinate plane and pass through exactly two of the labeled point on this graph? Where is the graph?

ask a tutor for help with that my dude I don't know sorry

Answer:

I use equal signs throughout but they are meant to be less than or equal to signs.

s=sandwiches

4.5s+6 less than or equal to 50

The answer is s is less than or equal to 12

Step-by-step explanation:

Finding Inequality

1. we know everything costs 50 in total so that is on one side of the equal sign.

____=50

2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.

____+6=50

3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.

4.5s+6=50

Solving

1. 4.5s-6=50

First use the addition property of equality and add 6 to both sides.

2. 4.5s=56

Then use the division property of equality and divide each side by 4.5

3. you get a decimal but since you can't buy half a sandwich the answer is

s is less than or equal to 12

Answer:

a) Negative 2.5 = negative 2 and one-half

Step-by-step explanation:

Which statements are true? Check all that apply.

Comparing the given options

a) Negative 2.5 = negative 2 and one- half

This is correct

b) –1.5 > –0.5

This is wrong

-0.5> -1.5

c) –0.5 < 0 –2.5 < –2

-0.5 < -2.5

This is wrong.

d) 1 and one-half greater-than 1.5

This is wrong

Therefore, only option a is Correct

Answer:

43.5 cm² and 112 cm²

Step-by-step explanation:

Here the instructions aren't given what to do. So I am finding the area of the ∆s .

Area of first ∆ :-

Area of second ∆ :-

Answer:

[tex] \displaystyle 3) \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

[tex] \displaystyle 4)\rm \boxed{112 {cm}^{2} }[/tex]

Step-by-step explanation:

we are given a triangle and we want to figure out the area of it Since we are given the base and the height we can consider the following formula

[tex] \displaystyle \frac{1}{2} bh[/tex]

from the triangle we can assume base and height as 14.5 and 8 respectively Thus substitute:

[tex] \displaystyle \frac{1}{2} (14.5cm)(6cm)[/tex]

reduce fraction:

[tex] \displaystyle (14.5cm)(3cm)[/tex]

simplify multiplication:

[tex] \displaystyle \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

our given shape is trapezoid

therefore recall that,

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h[/tex]

from the shape we define that

now substitute:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \frac{9cm + 19cm}{2} (8cm)[/tex]

reduce fraction:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (9cm + 19cm)(4cm)[/tex]

simplify addition:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (28cm)(4cm)[/tex]

simplify multiplication:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \boxed{112 {cm}^{2} }[/tex]

Answer:

The scale factor is = 0.75 ÷ 1.25 =

[tex] \frac{3}{5} = 0.6.[/tex] i.e. 3:5//

Answer:

738 square ft

Step-by-step explanation:

Area of the composite figure

= 21*(12 + 9 + 6) + 9*(9 + 6) + 6*6

= 21*27 + 9*15 + 6*6

= 567 + 135 + 36

= 738 square ft

Answer:

x=49

Step-by-step explanation:

2x+1=99

2x=98

x=49

Answer:

To find the value of x we need to solve this equation

2x + 1 = 99

now ,taking constant to right side

2x = 99 - 1

2x = 98

x = 98/2

x= 49
