Answer:

a

Step-by-step explanation:

Volume = l*b*h = (l*b)*h =Area of base * h

If we double the area of one face

then,New Volume = (2*area of base)*h

                      =2*(l*b)*h = 2lbh =2 * (volume)

Answer: 416 in^2

Step-by-step explanation:

a. Area of the Triangle x 2 + Area of Rectangle x 3

b. 8 x 7 / 2 x 2 + 8 x 15 x 3 = 56 + 360 = 416 in^2

Dilation scale factor:-

Hence he found the opposite scale factor which is for enlargement .

Answer:

D

Step-by-step explanation:

To find the scale factor of dilation, measure the distance between one of the points and the center of dilation for both the original shape and the dilated shape, then compare.

Distance from (0, 0) to point A = 9 units

Distance from (0, 0) to point A' = 2 units

Let x be the scale factor of dilation:

⇒ 9x = 2

⇒ x = 2/9

So the scale factor of dilation that reduces ΔABC to ΔA'B'C' is [tex]\sf \frac29[/tex].

Therefore, the mistake the friend made was finding the scale factor that enlarges ΔA'B'C' to ΔABC

well, from the picture, we can see the cylinder has a diameter of 5 and thus it has a radius of half that, or 2.5, and a height of "h", so

[tex]\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=2.5 \end{cases}\implies V=\pi (2.5)^2 h[/tex]

Pythagoras

c² = a² + b²

c being the Hypotenuse (the line opposite of the 90° angle) of the right-angled triangle.

9² = 5² + side²

81 = 25 + side²

56 = side²

side = sqrt(56) = sqrt(4×14) = 2×sqrt(14)

Answer:

14 Wood

Step-by-step explanation:

50/5 = 10 Wood = 4 days

70/5 = 14 Wood = 6 Days

I hope this is correct!

105  cords of wood could 7 woodchucks chuck in 6 days

Two or more expressions with an Equal sign is called as Equation.

If 5 woodchucks could chuck 50 cords of wood in 4 days, and since 1 woodchuck chucks 1/5 as much wood as 5 woodchucks, then we know that.

1 woodchuck could chuck 10 cords of wood in 4 days.

Then, since a woodchuck can chuck 1/4 as much wood in 1 day as she can chuck in 4 days, we conclude that

1 woodchuck could chuck 2.5 cords of wood in 1 day.

Now we use this to find the answer of our problem. If

In one day, If 1 woodchuck could chuck 2.5 cords of wood, then

In six days ,1 woodchuck could chuck cords of wood=6×0.25

7 woodchucks could chuck cords of wood in 6 days=6×0.25×7

=105

Hence 105  cords of wood could 7 woodchucks chuck in 6 days

Answer:

C. A reflection over the line y = -x

Step-by-step explanation:

You need to reflect that over a line that goes between the two of them. That imaginary line has a rise of -1 (it goes down 1 unit) and a run of 1 (it goes one unit to the right). In other words, the slope is -1. The line should also have a y-intercept of 0 it starts at (0,0).

Put that information in slope-intercept form

y = -1x + 0

You can take out the 0 because it adds nothing to the equation, and you can remove the one because of the same reason, but leave the negative sign.

y = -x

Step-by-step explanation:

The given quadratic equation forms a parabola when graphed, a U-shaped line.

To find the minimum value of y, we could find the y-coordinate of the vertex.

The vertex represents the maximum or minimum point on a parabola. It tells us the optimal y-value of the function and the x-value at which it occurs.

For the given quadratic, [tex]y=x^2+6x+7[/tex] the optimal y-value, or the y-coordinate of the vertex, will be a minimum. The [tex]x^2[/tex] value is positive, meaning the parabola will open upwards. (Please see below for an image representation).

There are multiple ways to approach this question.

One way is to rearrange the equation, which is currently in standard form, to vertex form.

Another way is to factor the equation to first find the x-intercepts of the graph, find the x-coordinate of the vertex, then at the end, plug the x-coordinate into the equation to find the minimum y-value.

The second strategy is a bit redundant for this type of question, so we can go about solving it by using the first method.

[tex]y=x^2+6x+7[/tex]

First, we can group [tex]x^2[/tex] and [tex]6x[/tex] by using a set of parentheses:

[tex]y=(x^2+6x)+7[/tex]

Then, we can complete the square:

[tex]y=(x^2+6x+(\dfrac{6}{2})^2)^2+7-(\dfrac{6}{2})^2[/tex]

[tex]y=(x^2+6x+9)^2+7-9\\\\y=(x^2+6x+9)^2-2[/tex]

Apply the rule [tex]a^2+2ab+b^2=(a+b)^2[/tex]:

[tex]y=(x+3)^2-2[/tex]

Therefore, the vertex of the quadratic is (-3,-2).

This makes the minimum y-value -2. The x-value at which this occurs is -3.

The minimum y-value -2. The x-value at which this occurs is -3.

Step-by-step explanation:

Because the only number that can go into 25 besides 1 is 5 and for 5 1 so your answer for the GCF or greatest common factor is 5.

hope this helps have a great day:)

Answer:

5

Step-by-step explanation:

As per the Euclidean Algorithm, GCF(X, Y) = GCF(Y, X mod Y)

where X > Y and mod is the modulo operator.

Here X = 25 and Y = 5

GCF(25, 5) = GCF(5, 25 mod 5) = GCF(5, 0)

GCF(5, 0) = 5 (∵ GCF(X, 0) = |X|, where X ≠ 0)

Therefore, the value of GCF of 5 and 25 is 5.

The inequality represents the sentence below is that the p minus 1. 4 greater-than 9.

Inequality equation is the equation in which the two expressions are compared with greater than, less than or other inequality signs.

Given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

Before solving it, first let's discuss the tenth and hundredths,

Here, the sentence given that the difference of a number and one and four tenths is more than nine and seventy-eight hundredths.

One and four tenths can be written as,

[tex]1\dfrac{4}{10}[/tex]

Nine and seventy-eight hundredths can be written as,

[tex]9\dfrac{78}{100}[/tex]

Let suppose the number is p. This difference of this number and one four tenths is more than nine and seventy-eight hundredths. Thus,

[tex]p-1\dfrac{4}{10} > 9\dfrac{78}{100}\\p-\dfrac{14}{10} > \dfrac{978}{100}\\p-1.4 > 9.78\\[/tex]

You could expand terms out and simplify, but I think it's more handy to leave it in this form so you can easily spot the center and radius from a glance.

The solution is, (x - 1)² + (y + 4)² = 100 , is the equation of a circle that is centered at (1,-4) with a radius of 10.

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. The perimeter around the circle is known as the circumference.

here, we have,

we know that,

the standard form of a circle equation is

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle, and r is the radius.

to get r² we simply use the given radius,

here, r = 10

so, we get,

r² = 100

now, circle that is centered at (1,-4)

so, we have,

(x - 1)² + (y + 4)² = 10²

we get, equation in standard form is therefore

(x - 1)² + (y + 4)² = 100

Hence, The solution is, (x - 1)² + (y + 4)² = 100 , is the equation of a circle that is centered at (1,-4) with a radius of 10.

According to the vertex and the directrix of the given parabola, the equation is:

[tex]y = \frac{3}{4}(x - 1)^2 + 4[/tex]

The equation of a quadratic function, of vertex (h,k), is given by:

[tex]y = a(x - h)^2 + k[/tex]

In which a is the leading coefficient.

The directrix is at y = k + 4a.

In this problem, the vertex is (1,4), hence:

[tex]h = 1, k = 4[/tex]

The directrix is at y = 7, hence:

[tex]4 + 4a = 7[/tex]

[tex]a = \frac{3}{4}[/tex]
