How would you find the scale factor in a dilation?

1 answer:

7 0

Starting with ΔABC, draw the dilation image of the triangle with a center at the origin and a scale factor of two. Notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). Dilation with scale factor 2, multiply by 2.

camille spends the same amount of money on lunch every day. on monday she bought a sandwich for 4.25 and two orders of fries. On

Ivahew [28]

Answer:

One order of fries costs 2

Step-by-step explanation:

She got 4.25 + two fries on Monday

She got 6.75 + one fries on Tuesday

Since she spends the same amount of money on lunch every day, both of the money that is spent must be equal.

Let f represent the cost of one order of fries, then equations can be written as follows:

4.25 + 2f (1)

6.25 + f (2)

Since both is equal:

→ 4.25 + 2f = 6.25 + f

→ f = 2

ε = {x: 2 x 30, x is an integer}, M = {even numbers}, P = {prime numbers}, T = {odd numbers} Find: I) MUP ii) M - T iii) P(MT) i

mariarad [96]

Answer:

Step-by-step explanation:

ε = {x: 2≤ x ≤30}

M = { even numbers} = {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

P = { prime numbers} = {2,3,5,7,11,13,17,19,23,29}

T = {odd numbers} = {3, 5, 7, 9, 11,13,15,17,19,21,23,25,27,29}

1. M ∪ P = {2,3,4,5,6,7,8,10,11,12,13,14,16,17,18,19,20,22,23,24,26,28,29,30}

2. M - T =

n(M) - n(T)

15- 14 = 1

3. P(MT)

(MT) = M ∩ T = 0

P ∪ (M ∩ T ) = {2,3,5,7,11,13,17,19,23,29}

4. P' = not a prime number

T' = not odd number = M

P' ∪(M∩T')

P' ∪ {2,4,6,8,10,12,14,16,18,20,22,24,26,28,30}

= {2,4,6,8,9,10,12,14,15,16,18,20,21,22,24,25,26,27,28,30}

The numbers of calories per serving for various snakes foods are listed below.

Elanso [62]

Answer:

B. 108 calories

Step-by-step explanation:

The mean number of a data set is

$\text{Mean}=\dfrac{\text{The sum of all calories in products}}{\text{The number of products}}$

Corn chips: 230 calories

Popcorn: 25 calories

Potato chips: 115 calories

Pretzels: 62 calories

Thus,

The sum of all calories $=230+25+115+62=432$

The number of productrs = 4

The mean number of calories $=\dfrac{432}{4}=108$
