Answer:

shipping cost $6 for a small box and $11 for a medium box

Step-by-step explanation:

The question is on formation of simultaneous equations

Anna shipped 10sb + 6mb =$126

Jeffrey shipped 5sb + 6mb=$96

Let small boxes,sb, be represented by x

Let medium boxes, mb, be represented by y

Equations

10x+6y=126------------------------(a)

5x+6y=96.......................................eliminate y by subtraction

5x=30.................................................divide by 5 to remain with x

x=30/5= 6......................................substitute value of x in equation (a)

(10×6) + 6y =126

60+6y=126

6y=126-60

6y=66..............................................divide by 6 both sides to get y

y=66/6= 11

Solution

x=6 and y=11

shipping cost $6 for a small box and $11 for a medium box

Answer:

The distance between the two trees is [tex]98.92\ ft[/tex]

Step-by-step explanation:

we know that

Applying the law of cosines

[tex]c^{2}=a^{2} +b^{2} -2(a)(b)cos (C)[/tex]

where

c -----> is the distance between the two trees

a ----> is the distance between the transit and the first tree

b ----> is the distance between the transit and the second tree

we have

[tex]a=62\ ft[/tex]

[tex]b=58\ ft[/tex]

[tex]C=111\°[/tex]

substitute and solve for c

[tex]c^{2}=62^{2} +58^{2} -2(62)(58)cos (111\°)[/tex]

[tex]c^{2}=9,785.38[/tex]

[tex]c=98.92\ ft[/tex]

Answer:

A reflection across the y- axis

Step-by-step explanation:

Under a reflection in the y- axis

a point (x, y) → (-x, y)

A point in the second quadrant (- x, y)

Under reflection in the y- axis is (x, y) ← point in first quadrant

Answer:

A reflection across the y-axis.

Step-by-step explanation:

If it was across the x-axis, the point would have gone into Quadrant III.

The y-axis is vertical, and it was moved into Quadrant I from Quadrant II making it a vertical reflection which is a reflection from the y-axis.

Answer: [tex]y=log_2(x-3)[/tex]

Step-by-step explanation:

To obtain the inverse of the function [tex]y= 2^x + 3[/tex], you need to solve the equation for the variable "x":

[tex]y= 2^x + 3\\\\y-3=2^x\\\\log_2(y-3)=log_2(2^x)\\\\x=log_2(y-3)[/tex]

Now you need to exchange the variable "x" with the variable "y". Then:

[tex]y=log_2(x-3)[/tex]

Finally, you get that the inverse of the function [tex]y= 2^x + 3[/tex] is:

[tex]y=log_2(x-3)[/tex]

Volume-πr^2h

r-11

h-15

11^2*15

=1815π

Answer:

The correct option is C.

Step-by-step explanation:

From the given figure it is clear that the radius of the cylinder is 11 units and the height of the cylinder is 5 units.

The volume of the cylinder is

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

Where, r is radius and h is height.

Substitute x=11 and h=15 in the above formula.

[tex]V=\pi \times (11)^2\times (15)[/tex]

[tex]V=\pi \times 121\times (15)[/tex]

[tex]V=1815\pi[/tex]

The volume of the cylinder is 1815π unit³.

Therefore the correct option is C.

Answer:

P (blue | black) = 0.151

Step-by-step explanation:

We know that there are 14 blue pens, 7 black pens and 5 red pens in Mrs. Johnson's desk drawer.

We are to find the probability of getting a blue pen and then a black pen when choosing two pens randomly without replacement.

Total pens = 14 + 7 + 5 = 26

P (blue pen) = 14/26

P (black pen) = 7/25

P (blue | black) = 14/26 * 7/25 = 49/325 or 0.151

For -4+2 you’d start at -4 then add two headed to the positive side

The sum of the expression -4 + 2 - 4 - 2 is shown on the number line that is negative 8.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The expression is given below.

⇒ -4 + 2 - 4 - 2

Firstly, subtract 4 from zero, then the line goes from zero to negative 4.

Secondly, add 2 from -4, then the line goes from negative 4 to -2.

Thirdly, subtract 4 from -2, then the line goes from negative 2 to -6.

And finally, subtract 2 from -6, then the line goes from negative 6 to -8.

Thus, the sum of the expression -4 + 2 - 4 - 2 is shown on the number line that is negative 8.

Answer:

B

Step-by-step explanation:

Given

y = f(x), then

y = f(x ± a) is a horizontal translation of a units

• If f(x + a) then shift of a units left ←

• If f(x - a) then shift of a units right →

When you transform a function by writing

[tex]f(x)\mapsto f(x+h)[/tex]

You're translating the function horizontally, h units to to the left if h is positive, and h units to the right if h is negative.

So, for example, given the "standard" parabola [tex]f(x)=x^2[/tex]

We have that the child function [tex]f(x+3) = (x+3)^2[/tex] has the same shape, but it's translated 3 units to the left.

V = 576 pi cm^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi *36*16

V = 576 pi cm^3

Answer:

y = (3/5)x + 3

Step-by-step explanation:

You can see immediately that the y-intercept is (0, 3).

As we go right from the point (-5, 0) to the point (0, 3), x increases by 5 and y increases by 3.  Thus, the slope of this line is m = rise / run = 3/5.

Starting with the generic y = mx + b, we get y = (3/5)x + 3.

Answer:

Y=3/2x-3

Step-by-step explanation:

3/2 is the slope. Remember, rise/run. so the rise is 3 and the run is 2. so up three since its positive and right 2 cuz its positive. and the -3 is the y inercept. hope this helps love :)

Answer:

The distance between two points is √169 or 13.

Step-by-step explanation:

In the question we need to find the distance between two points 5,6 and 0,-6 given.

Distance between two points can be found using the formula:

[tex]d(P1,P2) = \sqrt{(x_{2}-x_{1})^2 + (y_{2}-y_{1})^2}[/tex]

Putting the given points in the formula we get,

x₂ = 0, x₁ = 5, y₂= -6, y₁= 6

[tex]=\sqrt{(0-(5))^2 + (-6-(6))^2} \\=\sqrt{(0-5)^2 + (-6-6)^2}\\=\sqrt{(-5)^2 + (-12)^2}\\=\sqrt{25 + 144}\\=\sqrt{169}\\=13[/tex]

So, the distance between two points is √169 or 13.

Answer:

Inverse variation

Step-by-step explanation:

Given equation is [tex]y=\frac{3}{x}[/tex].

Now we need to identify the type of variation represented by  [tex]y=\frac{3}{x}[/tex].

We know that there are two type of variations direct and inverse.

If y and x are in direct variation then we write equation as  [tex]y=kx[/tex].

where k is the constant of variation.

If y and x are in inverse variation then we write equation as   [tex]y=\frac{k}{x}[/tex].

Given equation  [tex]y=\frac{3}{x}[/tex] looks similar to  [tex]y=\frac{k}{x}[/tex].

So that means finala answer is "Inverse variation".

Final answer:

To find out how many action figures are made per hour, divide the amount of plastic used per hour by the amount of plastic used to make one action figure. In this case, 113 action figures are made per hour.

Explanation:

To find out how many action figures are made per hour, we need to determine the amount of plastic used per hour and then divide it by the amount of plastic used to make one action figure.

First, we need to find the amount of plastic used per hour. Since 810 pints of plastic are used in an 8-hour shift, we divide 810 by 8, which gives us 101.25 pints of plastic per hour.

Next, we need to determine how many action figures can be made with 101.25 pints of plastic. We divide 101.25 by 90 (the amount of plastic used to make 600 action figures), which gives us 1.125 action figures per pint of plastic.

Finally, we multiply 1.125 by 101.25 to find the number of action figures made per hour. This gives us 113.4375 action figures per hour. Since we can't have a fraction of an action figure, we round this to the nearest whole number, which is 113 action figures per hour.

Answer:

So, Correct option is B i.e [tex]5.6^{-2} \times 3.4^{-11}\\[/tex]

Step-by-step explanation:

The expression here contains exponents so, we will use exponent rule.

The exponent rule says that the power of the same bases can be added if two same bases are multiplied i.e.

[tex]x^2 X y^2 X x^2 X y^1 \\can \,\, be \,\, written\,\, as\,\,\\x^{2+2} X y^{2+1}\\x^4 X y^3\\[/tex]

using this rule we can solve our question

[tex]5.6^{-5} \times 3.4^{-7} \times 5.6^3 \times 3.4^{-4}\\5.6^{-5+3} \times 3.4^{-7-4}\\ 5.6^{-2} \times 3.4^{-11}\\[/tex]

So, Correct option is B i.e [tex]5.6^{-2} \times 3.4^{-11}[/tex]

Answer

[tex] B)\: {5.6}^{ - 2} \times {3.4}^{ - 11} [/tex]

step-by-step explanation

For the expression

[tex] {5.6}^{ - 5} \times {3.4}^{ - 7} \times {5.6}^{3} \times {3.4}^{ - 4} [/tex]

we rewrite the expression to get

[tex] {5.6}^{ - 5} \times {5.6}^{3} \times {3.4}^{ - 7} \times {3.4}^{ - 4}[/tex]

One of the laws of indices states that

[tex] {a}^{m} \times {a}^{n} = {a}^{m + n} [/tex]

which means that if multiplying expressions of the same bases, repeat one of the bases and add the exponents

This implies that

[tex] {5.6}^{ - 5} \times {5.6}^{3} \times {3.4}^{ - 7} \times {3.4}^{ - 4} [/tex]

[tex]={5.6}^{( - 5 + 3)} \times {3.4}^{ (-7 - 4)}[/tex]

[tex]={5.6}^{-2} \times {3.4}^{-11} [/tex]
