Answer:

63 is the least common multiple of 7 and 9

Step-by-step explanation:

There is no number smaller than 63 that could be used as the the least common multiple so multiply 7 and 9. My friend daffy duck told me, math is mystery.

Step-by-step explanation:

Imagining living a life for five hundred years in the future, can have two perspectives considering the reality of today's society.

Let us suppose that we currently overcome all challenges related to preserving the environment, sustainable consumption, violence, and racial discrimination. Well, considering that point of view, a typical day five hundred years from now would be a lot of fun, I imagine that we would have great biodiversity preservation centers, people would be more cordial with others, everyone would have access to education and essential rights, and we would use more bicycles as a means of transport, because even if they had already managed to invent teleportation, the bicycle would still be a good option for the practice of physical exercises.

Answer: 12s+27j≤450

Step-by-step explanation:

From the question, we are informed that Jackie has a maximum of $450 to spend on shirts and jeans and that the shirts she wants to buy are $12 each, including tax while the jeans she wants to buy are $27 each, including tax.

The inequality that represents all possible combinations of s, the number of shirts, and j, pairs of jeans, Jackie can buy will be:

= 12s+27j≤450

Answer: 68 correct

Step-by-step explanation: 20% of 85 is the same thing as 85 times 0.2. that equals to 17. She got 17 wrong, so 85-17 equals to 68. She got 68 problems correct and 17 wrong.

The answer to this question is 68.

85 x  20%= 17

85 - 17 = 68

Answer:

The y intercept it 0 hours and 44

In this model y intercept represnts the lowest possible score obtainable due to lowest study.

The slope shows there is a direct correlation as x increases so does the value of y so it has a positive slope. All it represents is the more they studied the higher they score

Answer: $750

Step-by-step explanation:

We can solve this using direct proportion.

Let the number of minutes used be x

Let the cost be y

For direct proportion,y = kx

where, y = 250, x = 30

y = kx

250 = 30k

k = 250/30

k = 8.33

The cost to make a 90 minute movie will be:

y = kx

where,

y = unknown

k = 8.33

x = 90

y = 90 × 8.33

y = $750

The cost to make a 90 minute movie is $750.

Answer:

Rs 120

Step-by-step explanation:

Let MP = m

Discount = 25% of MP = m/4

SP = MP - Discount

= m - m/4 = 3m/4

If profit is 20%, CP = 3m/4 x 100/120 = 5m/8

=> Profit = 3m/4 - 5m/8 = m/8

Given Profit - Discount = Rs 15

=> |m/8 - m/4| = 15

m/8 = 15

m = Rs 120

Answer:

x>9

Step-by-step explanation:

Answer:

x > 9

Step-by-step explanation:

Simply solve for x.

What we have to do is subtract 3 from both sides, then divide by 5 to both sides.

5x > 45

x > 9

x is greater than 9.

#teamtrees #WAP (Water And Plant)

To find these out you have to use the strategy of P (parenthesis) E (exponents) M (multiplication) D (division) A (addition) S (subtraction)

3 - 4 x 2 The first thing you need to do is do the multiplication part first, since subtraction is the last thing you need to do. You multiply 4 and 2 and get the answer of 8, then subtract 3 which is 5

5 x 3 - 4 The first thing you need to do is multiplication 5 x 3 which equals 15 and then do 15 - 4 = 11

15 ÷ (3 x 5) x 2 The first thing you do is you do the P (parenthesis) which is (3x5) which equals 15. Then you multiply 15 with 2 which is 30 and then divide 30 with 15 which is 2

5 + 3 x 2 ÷ 6 First you need to do the Multiplication which is 3 x 2 which equals 6, and then you do the division, which is 6 ÷ 6 which is 1. Then add 5 to the 1 which is 6.

Answer:

The height of the tree is 14.85[tex]\bar 3[/tex] m

Step-by-step explanation:

The length of the shadow cast by the tree = 25 m

The length of the shadow cast by the signpost = 6 m

The height of the signpost = 3.5 m

Therefore, by similar triangles, we have;

Let θ, represent the angle formed by the line extending a line from the tip of the shadow, to the tip of the object and let x represent the height of the tree, we have

Tan(θ) = Opposite/Adjacent = Height of the object/(The length of the shadow)

∴ Tan(θ) = 3.5/6 = x/25

x = 25 × 3.5/6 = 14.58[tex]\bar 3[/tex]

The height of the tree = x = 14.85[tex]\bar 3[/tex] m

Answer:

  yes

Step-by-step explanation:

The width of the rectangle is given by ...

  W = A/L

  W = (20 cm²)/(8 cm) = 2.5 cm

__

The modified rectangle has a length of (8 cm +2 cm) = 10 cm, and an area of (20 cm² +4 cm²) = 24 cm². Its width will be ...

  W = (24 cm²)/(10 cm) = 2.4 cm

The percentage change in size is ...

  ((2.4 cm)/(2.5 cm) -1) × 100% = -4%

The width of the rectangle decreased less than 5%. Noah is correct.
