Step-by-step explanation:

-⅖ + ⁹/¹⁵ = 3/15

Answer 2

The correct answer for the given equation is  [tex]\frac{3}{15}[/tex].

What is PEMDAS?

PEMDAS is the right standardized way of solving math problems if multiple operations are being used. The acronym stands for parentheses, then exponents, then multiplication and division, then addition and subtraction.

Given the equation, [tex]-\frac{2}{5} -(\frac{-9}{15} )[/tex] if we follow the PEMDAS then we have to remove the bracket first, and after that negative sign before 9/15 will get positive as follow:

⇒  [tex]-\frac{2}{5} +(\frac{9}{15} )[/tex]

⇒    [tex]-\frac{6}{15} +(\frac{9}{15} )[/tex]

      [tex]\frac{3}{15}[/tex] .

Hence, The equation which shows the value of the given Problem is D.

If a rectangular field has a length of x+7 and a width of 4x-2, write an expression for the length of fencing to go around the outer edges.

I WILL MARK YOU THE BRAINLIEST!!!

Answers

Answer:

(2x+14) + (8x-4) = P

Step-by-step explanation:

P stands for perimiter

The expression for the length of fencing to go around the outer edges is  10x+10.

What is the perimeter of a rectangle?The perimeter of a rectangle is the twice the sum of length and width.Perimeter of a rectangle = 2(l+b)

Length of the rectangular field is given by x+7

and width is given by 4x-2

Length of fencing outer edges is equal to its perimeter.

Perimeter of a rectangle = 2(l+b)

=2(x+7+4x-2)

=2(5x+5)

=10x+10

Hence, the length of fencing outer edges is 10x+10

Answers

Answer:

The answer is C on Edge 2020

Step-by-step explanation:

The value of x will be 48.19°. Then the measure of angle LJK will be 41.81°.

What is a right-angle triangle?

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Triangle LJK is shown.

Angle ∠JLK is a right angle.

The length of the hypotenuse is 15 inches, and the length of the side adjacent to the right angle is 10 inches.

The angle between the 2 sides is x.

Then the measure of the angle x will be given by cosine of x.

cos x = 10 / 15

cos x = 0.667

      x = 48.19°

The value of x will be 48.19°.

We know that the sum of the angle of triangle is 180°.

Then the measure of angle LJK will be

∠LJK + 90° + 48.19° = 180°

                       ∠LJK = 41.81°

You are building a sand castle and want to use a bucket that holds a volume of 885 in.cubed and has height 11.7 in. What is the radius of the​ bucket? Use 3.14 for π.

Answers

Answer:

[tex]4.91 in[/tex]

Step-by-step explanation:

a bucket has the form of a cylinder, which has the following formula for its volume:

[tex]V=\pi r^2h[/tex]

where r is the radius and h is the height.

Since we need to find the radius, we solve for r:

[tex]r^2=\frac{V}{\pi h}\\ \\r=\sqrt{\frac{V}{\pi h} }[/tex]

and since we know according to the problem that:

[tex]V=885in^3[/tex]

and

[tex]h=11.7in[/tex]

substituing these values:

[tex]r=\sqrt{\frac{885in^3}{(3.14)(11.7in)}}\\ \\r=\sqrt{\frac{885in^3}{36.738in}}\\\\r=\sqrt{24.0895in^2}\\\\r=4.908in[/tex]

the radius is: [tex]4.908in[/tex] which can be rounded to [tex]4.91 in[/tex]

A variable is a quantity that can change; the word also refers to the letter or symbol that represents this quantity. In a proportional relationship, one variable is the independent variable, and one is the dependent variable. They are often called "x" and "y," but any letters can be used. The value of the dependent variable depends on the value of the independent variable. In the relationship between number of scoops of ice cream and total price, we can call number of scoops "x" and total price "y." Y is dependent because its value depends on x, the number of scoops you purchase. Ursula makes $5 for every 1 dog she walks.

The Anderson family has 3 kids 3 boys and 0 girls suppose that for each birth the probability of a boy birthday is 1/2 and the probability of a girl birth is also 1/2 what is the fractional probility of having 3 boys and 0 girls ina family first 3 births

Answers

Answer:

Fractional probability of having 3 boys and 0 girls in a family for first 3 births is [tex]\frac{1}{8}[/tex].

Step-by-step explanation:

Let A be the event of birth of a boy.

Let B be the event of birth of a girl.

Probability of birth of a boy, P(A) [tex]= \frac{1}{2}[/tex]

Probability of birth of a girl, P(B) [tex]= \frac{1}{2}[/tex]

We have to find the probability of birth of 3 boys i.e. event A occurring 3 times in a succession. It is independent events i.e. do not have any dependency on occurrence of any event.

So, Required probability can be calculated just by multiplying P(A) for 3 times.

i.e.

[tex]P(E) = P(A) \times P(A) \times P(A)\\\Rightarrow \dfrac{1}{2} \times \dfrac{1}{2} \times \dfrac{1}{2}\\\Rightarrow \dfrac{1}{8}[/tex]

So, the probability of having 3 boys and 0 girls in the family is [tex]\frac{1}{8}[/tex].

Evelyn borrowed $30 from her mother to buy a sweater. After 3 weeks of babysitting, she pays her mother back $24. ​ What percent of the debt has Evelyn paid her mother back?

Answers

Answer:

80%

Step-by-step explanation:

We know that Evelyn paid off $24 of the $30. To find the percentage, we divide the part by the whole and then multiply by 100. The multiplying by 100 is optional, but it just makes the calculation easier. In this case, the part is 24 and the whole is 30, so our expression would be [tex]\frac{24}{30} * 100[/tex], or 80%.

Harshdeep was playing basketball with his friends with seconds left before the game ended he attempted a 3 point shot the following equation models the path of the basketball y=-x^2+4x+5 where x is the elapsed time in seconds

Answers

Answer:

After two seconds, the ball reached 9 units up.

Step-by-step explanation:

The given function is

[tex]y=-x^{2} +4x+5[/tex]

The given function models the path of the ball.

The maxium height the ball reached is given by the vertex of this function, which has coordinates [tex]V(h,k)[/tex], where [tex]h=-\frac{b}{2a}[/tex] and [tex]k=f(h)[/tex].

From the equation, we know that [tex]a=-1[/tex], [tex]b=4[/tex] and [tex]c=5[/tex]. Replacing these values, we have

[tex]h=-\frac{4}{2(-1)}=2[/tex]

[tex]k=f(2)=-(2)^{2} +4(2)+5=-4+8+5=9[/tex]

Where [tex]k[/tex] determines the height and [tex]h[/tex] the time when the maximum height was reached by the ball.

The maximum height is 9 units.

Therefore, after two seconds, the ball reached 9 units up.
