what is the distance between points M(-3, 1)and N(7, -3)​

Answers

Answer:

d = 2√29 units

Step-by-step explanation:

M(-3, 1)and N(7, -3)​

To find the distance between these two points, we want to use the distance formula: d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Plug in the values.

d = √[(7 - (-3))² + (-3 - 1)²]

Simplify the parentheses.

d = √[(7 + 3)² + (-4)²]

d = √[(10)² + (-4)²]

Simplify the exponents

d = √[(100 + 16)]

Simplify the parentheses by adding.

d = √[116]

Simplify the brackets with the square root.

Since 116 is not a perfect square, we need to find two numbers that multiply to 116. One number must be a perfect square. The other must be a prime number.4 • 29 = 116. Therefore √4 • √29 = √116√4 = 2. Therefore 2√29 = √116

d = 2√29 units

Jackie is buying crackers and wants to know how many crackers are in the box. The box is 8 cm long, 2.4 cm wide, and 60 cm high. The dimensions of the crackers are 3cm long, 4 cm wide, and 5 cm high. How many crackers are in the box? Round to the nearest whole number. Geometry

Answers

Answer:

19

Step-by-step explanation:

Number of crackers that can be fit into the box = volume of the box / volume of crackers

Volume = length x width x height

volume of the box = 8 cm x 2.4 cm x 60 cm = 1152 cm^3

Volume of the crackers = 3cm x 4 cm x 5cm = 60cm^3

1152/60 = 19.2

Rounding 19.2 to the nearest whole number gives 19

Answers

He can buy 4
$30-$12=18
18 divided by 4= 4.5 so he can only buy 4

Let n = number of gum packs he buys.

After he starts with 30, spends 12, then spends 4n, he must have at least 0 remaining. So:

[tex]30-12-4n\geq 0[/tex]

Simplify by subtracting 30-12:

[tex]18-4n\geq 0[/tex]

Subtract 18 from both sides:

[tex]-4n\geq -18[/tex]

Divide both sides by -4 (flip the sign when you multiply or divide by a negative):

[tex]n\leq 4.5[/tex]

You can only buy a whole number of gum packs, so:

Cindy has a salary of $880 per week and is paid every two weeks. She has the following deductions from each paycheck: Federal income taxes: $195.82 State income taxes: $63.60 Insurance: $65.18 FICA: $134.64 Retirement plan: $176 What is Cindy's net income on each paycheck? Enter your answer as a number rounded to the nearest cent, such as: 150.12.

Answers

Answer:

244.80 If I'm not wrong.

Step-by-step explanation:

Add all of the deductions together and subtract them by 880

By using g00gle I found out that 195.82 + 63.60 + 134.64 + 176.00 = 635.24.

So now you subtract it by her salary down below:

880.00 - 635.24 = 244.76  

244.80 or 245 if I'm not wrong

Cindy's net income on each paycheck  will be $244.76.

What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given;

Federal income taxes: $195.82

State income taxes: $63.60

Insurance: $65.18

FICA: $134.64

Retirement plan: $176

Add all of the deductions together;

195.82 + 63.60 + 134.64 + 176.00 = 635.24.

So now we will subtract it by her salary down below:

880.00 - 635.24 = 244.76

Hence,  Cindy's net income on each paycheck  will be $244.76.

How many triangles can be constructed with angles measuring 50º, 90º, and 40º?

Answers

Answer:

Infinite

Step-by-step explanation:

We know that in a triangle the sum of all the interior angles must be 180°.

The given angles 50º, 90º and 40º

The sum of the angles 50º+ 90º + 40º= 180°

Thus, a triangle is possible with the given measurement.,

Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.

Similarly, all the triangles with the same measurements of the angles must be similar.

Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.

Carrie is planning to put photos in a photo album. She has 53 photos. Each page in the photo album can hold 9 photos. Carrie will fill each page with photos before starting on the next page. To find the number of pages she will need, Carrie calculates 53÷9. She gets a remainder of 8, so she decides that she will need 8 pages to place all of her photos in the photo album. Carrie's reasoning is incorrect. Explain The mistake Carrie makes. Enter your explanation in the space provided.

Answers

Answer: Carrie will only need 6 pages. Because 5 pages hold 45 pictures. And then she has 8, which all can fit in one other page. So 5 + 1 = 6. Therefore she only needs 6 pages not 8.

Please show step by step how you got the answer

Answers

Answer:

(5, 11 )

Step-by-step explanation:

Given the 2 equations

y = 3x - 4 → (1)

y = 2x + 1 → (2)

Substitute y = 3x - 4 into (2)

3x - 4 = 2x + 1 ( subtract 2x from both sides )

x - 4 = 1 ( add 4 to both sides )

x = 5

Substitute x = 5 into either of the 2 equationsfor corresponding value of y

Substituting into (2)

y = 2(5) + 1 = 10 + 1 = 11

solution is (5, 11 )

Answer:

This is a system. put the first equation under the second one and subtract. y - y = 0. 2x - 3x = -x. 1 - (-4) = 5. so the result is 0 = -x +5 or x = 5. plug x into either equation and y = 11. the answer is (5, 11).
