Mr. Rozario bought some apples and oranges. The ratio of the number of apples to the number of oranges are 2:5. He gave 3/4 of the apples to his sister and 34 oranges to his brother. The ratio of the number of oranges to the number of apples that he has now is 2:3.
How many apples did Mr. Rozario buy?
How many oranges did Mr. Rozario buy? Please help fastttttttt
Answer:
How many apples did Mr. Rozario buy?
16 apples
How many oranges did Mr. Rozario buy? 40 oranges
Step-by-step explanation:
From the question, we know that:
The ratio of the number of apples to the number of oranges are 2:5.
We represent the total number of fruits as x
Let
The number of apples he bought be represented as 2x
The number of oranges he bought be represented by
= 5x
He gave 3/4 of the apples to his sister and 34 oranges to his brother.
This means now, the number of apples he has left =1 - 3/4(2x) = 1/4(2x)
The number of oranges he has left = 5 - 34
The ratio of the number of oranges to the number of apples that he has now is 2:3.
1/4(2x) : 5x - 34 = 2:3
x/2:5x - 34 = 2:3
= x/2/5x-34 = 2/3
Cross Multiply
(x/2)3 = 5x - 34(2)
3x/2 = 10x - 68
Cross Multiply again
3x = 2(10x - 68)
3x = 20x - 136
20x - 3x = 126
17x = 126.
x = 126/17
x = 8
Hence:
The number of apples he bought be represented as 2x
So: 2 × 8 = 16 apples
The number of oranges he bought be represented by
= 5x
so: 5 × 8 = 40 oranges
Therefore, the number of Apples Mr Rosario bought is 16 apples
The number of oranges Mr Rosario bought is 40 oranges

you flip a coin twice what is the probability of getting tails then getting heads
HELP ASAP
Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.

The cost of cookies at store A are shown in the graph. The cost y for x cookies at store B is represented by the equation y=0.30x. Which of the following statements is true?
The relationship between the cost of cookies and the number of cookies is
a proportional relationship.
Correct response:
c. The cookies at store B cost moreMethod by which the above option is selectedThe function of the given graph for the cost of cookies at store A is found as follows;
The graph is a straight line passing through the origin, therefore, the equation is of the form;
y = m·x
The cost of 2 cookies = $0.5
Therefore;
The cost of 1 cookie at store A = $0.5 ÷ 2 = $0.25
Therefore, the cost of y cookies = 0.25·x
Where;
x = The number of cookies
The equation representing the cost y for x cookies in store B in dollars is given as follows;
y = 0.30·x
Therefore, the cost of 1 cookie at store B = $0.30 × 1 = $0.30
Therefore;
The cookies at store B cost moreLearn more about the proportional relationships here:

Which statement best describes the zeros of the function h(x) = (x + 9)(x2 - 10x+ 25)?
ОА.
The function has three complex zeros.
OB. The function has three distinct real zeros.
OC.
The function has one real zero and two complex zeros.
OD.
The function has two distinct real zeros.
Step-by-step explanation:
h(x) = (x + 9)(x² - 10x + 25) = (x + 9)(x - 5)²
When h(x) = 0, (x + 9) = 0 or (x - 5)² = 0.
=> x = -9 or x = 5.
Hence there are 2 distinct real roots of h(x).

Answer:
regular tessellation
Step-by-step explanation:
A regular tessellation is a repeating pattern of congruent regular polygons on a plane with no gaps or overlaps.
Since a regular tessellation is with no gaps and overlaps, the only regular polygons that will tessellate are equilateral triangles, squares and regular hexagons. Therefore, there are only three types regular tessellations (ones made from squares, equilateral triangles and hexagons),
