what would be the right answer to 71,526 + 262

Answer: y = [tex]\frac{1}{4}[/tex]x - 3 [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

    Slope-intercept form is in the form of y=mx + b where m is the slope and b is the y-intercept.

    We are given the slope, so we will plug this in.

y = mx + b

y = ([tex]\frac{1}{4}[/tex])x + b

    Now, we will solve for the y-intercept by plugging in the point they give us.

y = ([tex]\frac{1}{4}[/tex])x + b

(-2) = ([tex]\frac{1}{4}[/tex])(5) + b

-2 = 1.25 + b

-3 [tex]\frac{1}{4}[/tex] = b

    Lastly, we will plug this variable into the equation we wrote above for our final answer.

y = [tex]\frac{1}{4}[/tex]x - 3 [tex]\frac{1}{4}[/tex]

Answer:

13.994[tex]cm (5.sf)[/tex]

Step-by-step explanation:

We know that the base of the cylinder is a circular base.

So circumference of base = [tex]2\pi r[/tex]

Given [tex]2\pi r=22cm\\\\r=\frac{22}{2\pi } \\r=\frac{11}{\pi } cm\\[/tex]

Volume of a cylinder = [tex]\pi r^{2} h[/tex] = 539[tex]cm^{3}[/tex]

Substitute r into the formula for volume of cylinder.

[tex]\pi (\frac{11}{\pi } )^{2} h=539\\\pi (\frac{121}{\pi ^{2} } )h=539[/tex]

Now, we will cancel [tex]\pi[/tex] from the numerator and denominator.

[tex](\frac{121}{\pi } )h=539\\h = \frac{539}{\frac{121}{\pi } } \\h = 539 * \frac{\pi }{121} \\h = 13.994cm(5s.f)[/tex]

Answer:

Aproximated height is:

14 cm

Step-by-step explanation:

volume of a cylinder = л r² h

л = 3.1416 (aprox)

r = radius

h = height

r = circunference/2л

r = 22/(2*3.1416)

r = 3.5    (aprox)

then volume is:

539 = 3.1416 * 3.5² * h

539 = 3.1416 * 12.25 * h

539 = 38.5 * h

h = 539/38.5

h = 14 cm     (aprox)

Answer is in the photo

Step-by-step explanation:

The formula for multiplying two numbers with same base but different exponents is

a^m×a^n= a^(m+n)

The area of the window is 8[tex]m^{2}[/tex].

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely cover the surface of a closed figure.

The word "area" refers to a free space. The length and width of a form are used to compute its area.

Any shape's area can be calculated by counting how many unit squares will fit inside of it.

According to the question,

Length of window=2m

Width of window=4m

Area of window=Length*Width

Answer:

Just look at the other answer

Step-by-step explanation:

The given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial.

A perfect square trinomial is takes the algebraic expression form ax^2 +bx + c, where the square root of the first term and the third term is the equation to the second term.

Given that:

-(3x + 5)^2

Open brackets

= - (9x +30x + 55)

Multiply through by (-)

= -9x^2 - 30x - 55

Therefore, we can conclude that the given equation-(3x + 5)^2 is not a perfect trinomial because it is not obtained through the multiplication of a binomial. i.e. the multiplication of the square root of the first and the third term did not result in the 2nd term.

Answer:

D. 62.5

Step-by-step explanation:

2 ways

1.

7.5 ÷ 3 = 2.5

25 times 2.5 = 62.5

2.

3/7.5 = 25/x

3x = 187.5

187.5 ÷ 3 = 62.5

The actual distance for a length on a map is 62.5. so correct option is D.

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

Given The scale on a map reads 3 inches = 25 miles.

If two cities are 7.5 inches apart on the map,

Find the actual distance for a length on a map.

Let x be the actual distance

7.5 ÷ 3 = 2.5

25 times 2.5 = 62.5

Thus,

3/7.5 = 25/x

3x = 187.5

187.5 ÷ 3 = 62.5
