How much would each orange weigh if the total weight of all the oranges were distributed equally?

Answers

Answer:

Weight of each orange = Total weight of all the oranges ÷ Number of oranges

Step-by-step explanation:

Given: Total weight of all the oranges were distributed equally

To find: weight of each orange

Solution:

As total weight of all the oranges were distributed equally,

Number of oranges × weight of each orange = Total weight of all the oranges

Therefore,

Weight of each orange = Total weight of all the oranges ÷ Number of oranges

AE / AD = AB / AC

51 / 51 + 17 = x / x + 12

51 / 68 = x / x + 12

51 ( x + 12) = 68x (After cross multiplication)

51x + 612 = 68x

612 = 68x - 51x

612 = 17x

x = 612/17 = 36

Each event uses a standard deck of playing cards. The cards are chosen at random and put back after each draw.
Match each event with its theoretical probability.
You choose a red card.
You choose the queen of hearts.
You choose a club.
You choose a 5, 6, or 7. 11 :: 3 13 52

PUT THEM IN ORDER! AND I'LL GIVE YOU "⭐"

Answers

Answer:

See below

Step-by-step explanation:

The probability of choosing a red card is 1/2. Half of the cards are hearts/diamonds and half of the cards are clubs/spades.

The probability of choosing the queen of hearts is 1/52. There is one queen of hearts in a 52 card deck.

The probability of choosing a club is 1/4. 1/4 of the cards are clubs, 1/4 are spades, 1/4 are diamonds, 1/4 are hearts.

The probability of choosing a 5, 6, or 7 is 3/13. There is a 5, 6, 7 in all 4 sets, clubs, spades, hearts, and diamonds. So there are 12 total cards that either read 5, 6, or 7 out of the 52 total cards. 12/52 simplifies to 3/13.

is x²-x divisible by 2?

Answers

Answer:

Yes

Step-by-step explanation:

There are two cases: Case 1: x is even, so x can be modelled as a generic number 2n, where n is a positive integer. Clearly this product is divisible by two. ... Hence, it is safe to generalise that the term x²-x is divisible by 2 for any positive integer x.

Step-by-step explanation:

No, because [tex](x^2-x)/2[/tex] does equal [tex]x^2/2-x/2[/tex]. Honestly, it really depends on the value of x, as it provide whether or not the expression is divisible by 2.

Are the pink arcs congruent?

Answers

Answer:

Yes, they are congruent.

Step-by-step explanation:

Supplementary angles equal up to 180°.

70+40 = 110

180 - 110 = 70.

Angle BAE is 70°.

And, angle ADC is 70° as well.

Therefore, the pink arcs are congruent.

Find g(x), where g(x) is the translation 4 units down of f(x)=x2. Write your answer in the form a(x–h)2+k, where a, h, and k are integers. g(x)=

Answers

Answer: g(x) = (x+3)^2

The answer should be in the form of a(x-h)2 + k.

Since we are not translating up or down, the k value is 0. We will not be adding any values to the outputs of the original equation here. a will equal 1 since no stretches are occurring. So we are left with the h value.

f(x) = x2 is given.

g(x) = a horizontal translation of 3 units left. This means that the h value is -3, because in order to move left, you need to take 3 away from all x values (inputs). So the point (2,4) on f(x) would become (-1,4) on g(x).

How do we write this?

g(x) = f(x-h) where h = -3.

So this is g(x) = f(x - (-3)) = f(x+3)

g(x) = (x+3)^2

The sun causes a flagpole to cast a shadow that measures 85 ft. from the base of the pole. At the same time of the day, a 6.5 ft. tall basketball player casts a shadow that measures 9.75 ft.

The basketball player’s little sister is 3.5 ft. tall. At the same time of the day, determine her shadow’s length to the nearest tenth of a foot.

Answers

Answer:

Length of the shadow of player's sister is 5.25 feet.

Step-by-step explanation:

From the figure attached,

AB represents the basketball player and DE is his little sister.

Height of basketball player = 6.5 ft

Length of shadow of the player = 9.75 ft

Height of player's sister = 3.5 ft

Since, ΔABC and ΔEDC are the similar triangles, their corresponding sides will be proportional.

[tex]\frac{AB}{DE}= \frac{ED}{DC}[/tex]

[tex]\frac{6.5}{3.5}= \frac{9.75}{x}[/tex]

x = [tex]\frac{9.75\times 3.5}{6.5}[/tex]

x = 5.25 ft

Therefore, length of the shadow of player's sister is 5.25 feet.

The base of a ladder is 10 feet from the side of a building. The top of the ladder reaches a window that is 24 feet above the ground, What is the length of the ladder? A. 14 ft B. 22 ft C. 26 ft D. 34 ft

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the concept of Pythagorus theorem,

here, the perpendicular height = 24 ft and the base = 10ft ,

hence then length of the ladder is the Hypotenuse.

so we get as,

[tex]l \: = \sqrt{ {24}^{2} + {10}^{2} } [/tex]

[tex]l \: = \sqrt{576 + 100} [/tex]

[tex]l \: = \sqrt{676} [/tex]

hence, l = 26 ft

so the length of the ladder is 26 feets.
