help me please!!! i will mark brainliest on the first one to answer :)) (that's not a scam) picture question

Answer:

89/56 (first option)

Step-by-step explanation:

The LCD (or Least Common Denominator) of all the fractions is 840.

5/7 (the smallest number) is equivalent to 600/840, while 7/8 (the largest number) is equivalent to 735/840.

600/840 + 735/840 = 1335/840, which reduces to 89/56.

Hope this helps!

Answer:

10 inches

Step-by-step explanation:

we know that 2 inches is equal to 50 miles, so:

2x = 50

x= 25, which means that 1 inch is 25 miles.

250/25 = 10, which means that it would take 10 inches to be equal to 250 miles.

Provided That :-

Answer:

Vertex form: y = 3(x + 2)² + 2

Step-by-step explanation:

Given the graph of an upward-facing parabola, whose vertex occurs at point (-2, 2):

The vertex form of a quadratic equation is given by:  y = a(x - h)² + k

where:

(h, k) ⇒ vertex

h =  indicates a horizontal translation of the graph.

k =  indicates a vertical translation of the parabola.

x = h ⇒ axis of symmetry: the imaginary vertical line that divides the graph into two symmetrical parts.

a = direction of the parabola's opening; determines the wideness of the graph.

Now that we have established the necessary terms related to understanding the concept of quadratic equations, we can proceed with determining the equation of the graph.

Besides the vertex, (-2, 2), we must choose another point on the graph to solve for the value of a.  Using the point from the graph, (-1, 5), along with the vertex, substitute these values into the vertex form to solve for a:

y = a(x - h)² + k

5 = a[-1 - (-2)]² + 2

5 = a(-1 + 2)² + 2

5 = a(1)² + 2

5 = a + 2

Subtract 2 from both sides:

5 - 2 = a + 2 - 2

3 = a

Therefore, the vertex form of the given graph of a parabola is:

y = 3(x + 2)² + 2

Using an exponential function, it is found that the projected growth rate is of 4.5%.

An increasing exponential function is modeled by:

[tex]A(t) = A(0)(1 + k)^t[/tex]

In which:

In this problem:

We use the information given to solve for k.

[tex]A(t) = A(0)(1 + k)^t[/tex]

[tex]37.1 = 23.9(1 + k)^{10}[/tex]

[tex](1 + k)^{10} = \frac{37.1}{23.9}[/tex]

[tex]\sqrt[10]{(1 + k)^{10}} = \sqrt[10]{\frac{37.1}{23.9}}[/tex]

[tex]1 + k = \left(\frac{37.1}{23.9}\right)^{\frac{1}{10}}[/tex]

[tex]1 + k = 1.045[/tex]

[tex]k = 0.045[/tex]

The growth rate was of 4.5%.

Explanation:

It helps to make a table of all possible outcomes. Refer to the diagram below. Along the top we have the outcomes 1,2,3,4. Along the left side we have 2,3,4,5. Each row & column header is then added to form the corresponding inner cell. For example, in the top left corner we have 1+2 = 3.

There are 4 outcomes of spinner A and 4 outcomes of spinner B. This means we have 4*4 = 16 outcomes overall. Out of those 16 sums, we have the odd results {3,5,7,9} show up 1+3+3+1 = 8 times.

The probability we want is therefore 8/16 = 1/2. This is expected since half of the values of {1,2,3,4} are odd, and the same applies to {2,3,4,5}. So we should expect half of the sums to be odd as well.

Put another way: for any row or column, you'll find that the pattern is odd/even/odd/even or even/odd/even/odd. This shows that 50% of any row or column represents an odd number. This idea extends out to the entire table overall.

Answer:

1/2.

Step-by-step explanation:

There are 2 odd and 2 even numbers on each spinner.

Odd totals will come from an odd number from the first spinner and an even number from the second spinner, or vice versa.

So the number of possibilities  of an odd total = 2 * (2 * 2) = 8.

The total number of all possible outcomes = 4*4 = 16.

So the required probability is 8/16 = 1/2.

Step-by-step explanation:

Your choice is correct.

The sequence is:

The difference is not common:

Correct choice is A

Count the squares

Lets find common difference

Answer:As most maths problems, you don’t have to convert it immediately in numbers to solve it.

It’s obvious that John works twice as fast as Tom to paint the same surface. It means that if they work simultaneously, at any time John will always have painted twice as much surface as Tom. So if they plan it properly and they end the painting of the room at the same time, John will have painted twice as much surface as Tom.

There is only one possibility : if Tom painted 1/3 of the room and John painted 2/3.

Now, if Tom painted 1/3 of the room it probably took him 1/3 of the time needed to paint the entire room, or 12/3=4 hours. It also works for John : 6*2/3=4 hours
