Hello

60 %  are girls

40 % are boys

40 % = 50 boys

60 % =  75 girls

75 + 50 =  125

Step-by-step explanation:

Let number of students be X

Percentage of boys=100-60=40%

No of boys= 40% of X

50= 40×X/100

X= 50 × 100/40

X =125 total number of students

Answer: 28

Step-by-step explanation:

Given: First group received 28 baseball cards and second group received 84 baseball cards.

Total cards= 28+84 =112

If each person entering the stadium received the same number , the  greatest number of baseballs cards they could have received = G.C.D. (28,84,112)

[G.C.D. = greatest common divisor]

Since the prime factorization of 28 , 84 and 112 are as follows

28 = 2 x 2 x7

84 = 2 x 2 x 3 x 7

112 = 2 x 2 x 2 x 2 x 7

G.C.D (28, 84, 112 )= 2 x 2 x7 = 28

The greatest number of baseballs cards they could have received = 28

The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

[tex]\rm y = a \ e^{bx}\\[/tex]

From the graph, at x = 0, the value of the function is 4. Then we have

[tex]\rm \\4= a \ e^{b\times 0}\\[/tex]

a = 4

Then the exponential equation is given as,

[tex]\rm y = 4e^{bx}[/tex]

From the graph, at x = 1, the value of the function is 2.426. Then we have

[tex]\rm 2.426 = 4 e ^b \\\\e^b = 0.6065[/tex]

Take natural log on both sides, then we have

b lne = ln 0.6065

b = - 0.50

Then the exponential equation is given as,

[tex]\rm y = 4 \ e^{-0.50x}[/tex]

The function that could produce the graph will be [tex]\rm y = 4 \ e^{-0.50x}[/tex]. Then the correct option is B.

Answer:

she'll have 8 plates with 7 spring rolls and 9 plates with 9 cheese cubes.

Step-by-step explanation:

This is a right triangle. Use the Pythagorean theorem to solve:

x^2 + 5.8^2 = 15.6^2

x^2 + 33.64 = 243.36

Subtract 33.64 from both sides:

x^2 = 209.72

Take the square root of both sides:

x = 14.48171

Round to 1 decimal place:

x = 14.5 in.

Answer:

x = 14.5 in

Step-by-step explanation:

There is something called pythagoras' theorem. It states that

a^2 + b^2 = c^2,

a, b and c being sides of a right-angled triangle.

C is always the hypotenuse and a and b are any of the other two.

(The hypotenuse is always the longest side, and always opposite to the right angle, which is always the biggest angle of a right-angled triangle.)

So here we know two sides, the hypotenuse and another side. Let's substitute them into the formula:

5.8^2 + x^2 = 15.6^2

x^2 = 15.6^2 - 5.8^2

x^2 = 243.36 - 33.64

x^2 = 209.72

x = sqr209.72

x = 7sqr107/5 = 14.48171261 in

= 14.5 in (if rounded to 3 significant figures)

You could use a shortcut to do all this and find the answer more quickly:

a^2 = c^2 - b^2 or b^2 = c^2 - a^2

also:

a = sqr(c^2 - b^2)

x = Sqr(15.6^2 - 5.8^2)

= 14.5 in

Answer:

Plus 2 (+2)

Step-by-step explanation:

The rate of change is always a constant change from the given first term to the next one. In this case, you are adding 2 each time:

3 + 2 = 5

5 + 2 = 7

7 + 2 = 9

etc.

~

Change means difference in the state or condition of a thing and here the thing is number. The change made within them must be following some certain rules or patterns.

They can be uniform and here it is uniform for sure. The terms are increasing by 2 or we can say that for getting th next number, we need to add 2 with the previous.

So, the rate of change for the above numbers or number series is +2 or addition of 2[tex].[/tex]

Step-by-step explanation:

First of all, [tex]\frac{-1}{-2}[/tex] is equal to [tex]\frac{1}{2}[/tex] because a negative divided by a negative is positive. So now we've got [tex]2a^\frac{1}{2}[/tex]. Well, a fractional exponent, when simplified, is a root. For example, [tex]x^\frac{1}{3}[/tex] is equal to [tex]\sqrt[3]{x}[/tex], and [tex]x^\frac{2}{5}[/tex] is equal to [tex]\sqrt[5]{x^2}[/tex].

Now this is where people make mistakes. Remember, [tex]2a^\frac{1}{2}[/tex] is really [tex]2*a^\frac{1}{2}[/tex], which means only a is raised to the exponent. We would only raise 2a to the power of [tex]\frac{1}{2}[/tex] if our term was [tex](2a)^\frac{1}{2}[/tex]. But since our term is [tex]2*a^\frac{1}{2}[/tex] we raise a to the power of [tex]\frac{1}{2}[/tex] which is the same as [tex]\sqrt[2]{a}[/tex] or just [tex]\sqrt{a}[/tex]. Then we multiply that result by 2 and we have [tex]2\sqrt{a}[/tex] which is fully simplified.

Step-by-step explanation:

Reflection  over the y-axis--->  (a, b) transforms to (-a, b).

So  A (1, 6) --->   A' (-1, 6).

Answer:

The answer is A

Step-by-step explanation:

You are not changing -14 into 14, you are just simply saying that you are adding more negative to -14, so instead of saying minus 6, you are saying adding -6. you are still going down on a number line either way.
