Answer:

Step-by-step explanation:

AC = length of flagpole = 12 ft

AB = length of shadow = 14 ft

BC = length from the top of the flagpole to the end of the shadow = x ft

Use Pythagorean theorem to find the length of x,

x² = AC² + BC²

   = 12² + 14²

  = 144 + 196

  = 340

x = √340

x = 18.4 ft

Answer:

9x^5*y^2*pi

Step-by-step explanation:

a = pi * r^2

a = pi * 9x^5y^2

a = 9x^5y^2pi

Answer:

615.44 mm²

Step-by-step explanation:

Before finding the area of the circle, first, let us find the radius of the circle.

Given that,

diameter ⇒ 28 mm

Therefore,

28 = 2r

Divide both sides by 2.

14mm = radius

And now, let us find the area.

The formula to find the area of the circle is :

Let us solve now.

Area = π r²

        = 3.14 × 14 × 14

        = 43.96 × 14

        = 615.44 mm²

The answer is C. $56.00
Hazel earned $56.00 in interest after one year.

Step-by-step explanation:

700 x 6.5% =
700 x 0.065 = 45.5

300 x 3.5% =
300 x 0.035 = 10.5

45.5 + 10.5 = 56.00

Answer:

C. 9 cubic units

Step-by-step explanation:

The formula for the volume of a prism is V=Bh, where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 4 and the width is 3/2 (1 1/2 = 3/2). The area A of a rectangle with length l and width w is A=lw

so the area of the base is 4 x 3/2 which is 6

then we multiply that by the height (3/2) to get 9.

Answer:

<-----10%-----1/4------3/4----->

The top left most answer (or A)

Step-by-step explanation:

Let's get all of these terms into the same representation. Meaning let's convert all of the numbers into either fraction or a decimal or percentage.

I find that fraction would be hard and so would percentage, lets try decimal.

1/4 = 0.25 as a decimal. (1/4 = 25/100 = 0.25) 3/4 = 0.75 (same manner as 1/4) Now for 10%. 10% in technical speaking is equal to 10/100 again which means it would be 0.10.

Okay so now they're all decimals let's put them in ascending order!

0.10, 0.25, 0.75. Yay! Now we can see on a number line the order would be

<-----10%-----1/4------3/4----->

I hope this helps!

Answer:

x = 698.771

step-by-step explanation:

[tex]\sf \rightarrow \log _{2x}\left(5^{\dfrac{3}{2}}\right)=\dfrac{1}{3}[/tex]

apply ln rules

[tex]\sf \rightarrow \dfrac{\ln \left(5^{\dfrac{3}{2}}\right)}{\ln \left(2x\right)}=\dfrac{1}{3}[/tex]

cross multiply

[tex]\sf \rightarrow \ln \left(5^{\dfrac{3}{2}}\right)\cdot \:3=\ln \left(2x\right)\cdot \:1[/tex]

simplify using calculator

[tex]\sf \rightarrow 7.24247 = ln(2x)[/tex]

shift sides

[tex]\sf \rightarrow e^{7.24247 }= 2x[/tex]

divide both sides by 2

[tex]\sf \rightarrow 698.771= x[/tex]

Answer:

[tex]x=698.771[/tex]

Step-by-step explanation:

[tex]log_{2x} (5\frac{3}{2})=\frac{1}{3}[/tex]

[tex](5\frac{3}{2})*3=In(2x)*1[/tex]

[tex]7.24247=In(2x)[/tex]

[tex]e^{7.24247}=2x[/tex]

÷ [tex]2[/tex]           ÷ [tex]2[/tex]

[tex]698.771=x[/tex]

I've arranged the tiles into the correct positions, and wrote in the final result for each x and y.

The basic idea is to divide determinants as the vertical bars indicate (they aren't absolute value bars).

In each denominator is the determinant of the matrix [tex]\begin{bmatrix}2 & 1\\-3 & 4\end{bmatrix}[/tex] which are the coefficients of the left hand side of each original equation given to you.

-------------

The numerators are a slight variation of this matrix. The x determinant will have you replace the first column with 0 & 22 getting [tex]\begin{bmatrix}0 & 1\\22 & 4\end{bmatrix}[/tex] which helps figure out the x solution. The y solution is similar as well, but we replace the y column instead of the x column. So that explains the [tex]\begin{bmatrix}2 & 0\\-3 & 22\end{bmatrix}[/tex]

After you have the proper determinants set up, you just evaluate each determinant using the formula

[tex]\begin{vmatrix}a & b\\ c & d\end{vmatrix} = a*d - b*c[/tex]

and then simplify the results.

Hey there!

A geometric sequence is where we use multiplication or division to get to the next term.

In this case, we use multiplication (we multiply every term by 3)

So we have

Answer:

$500

Step-by-step explanation:

if Marco gets $50 for every 2 hours and it say how much he'll have every 10 hours what your gonna do is multiply 10 by 50 so 10×50= 500 so Marco will make $500 every 10 hours

$250 will he make in 10 hours for the work that Marco has done.

When you take a single number and multiply it by several, you are multiplying. There are a number of distinct indications of amplification that people utilize. The "x" sign represents the most typical, however, other symbols like the "*" sign are also occasionally used.

The information that is provided is:

Marco made $50 for the two hours he is working for.

For one hour of the work that he is doing the amount that he will be paid is

= 50 / 2

$25

For working 10 hours Marco will earn

= 10*25

$250

and that gives you how many friends

Given -

x² + 4x + 1 = -3

To find -

the discriminant for the quadratic equation and to find how many real number solutions does the equation have. If it's discriminant = b² - 4ac

Concept applied -

As we know, Discriminant = b² - 4ac

A quadratic equation ax²+ bx + c = 0 has -

Solution -

Solving the quadratic equation to bring it in the form of ax² + bx + c = 0,

➛ x² + 4x + 1 = -3

➛ x² + 4x +3 + 1 = 0

➛ x² + 4x + 4 = 0

Here,

a = 1, b = 4 and c = 4.

Putting the values in the the formula, b²- 4ac = 0.

➙ (4)²- 4(1)(4)

➙ 16- 16

➙ 0

As, b²- 4ac = 0 hence the quadratic equation will have two equal roots (i.e., coincident roots).

Answer:

1 aka b

Step-by-step explanation:

Check out the diagram below.

Since D and E are midpoints of AB and AC this means midsegment DE is parallel to side BC. Furthermore, it means DE is parallel to PQ because PQ is entirely on BC.

---------

Note how I drew a line from A to O. This forms two triangles ABO and ACO

For triangle ABO, segment DP is a midsegment because D and P are midpoints of AB and OB respectively. This means side DP is parallel to side AO. Keep this in mind as we'll use it later.

For triangle ACO, segment EQ is parallel to AO because EQ is a midsegment for similar reasons as already mentioned (E and Q are midpoints of AC and OC respectively). So this must mean that AO is parallel to EQ

Now chain the arguments together: if DP || AO and AO || EQ, then DP || EQ by the transitive property.

-----------

In short, we've proven two things

This is enough to conclude that DEQP is a parallelogram. By definition, a parallelogram has two pairs of opposite parallel sides.

Answer:

8

Step-by-step explanation:

if a = -b, then -a = b.

plug that into the (b = -c) problem, and you get -a = -c, or a = c

if a and c ar equal, then and b = -c, b also equals -a.

the problem then becomes a - b +c, where a = 8, c = 8, and b = -8

a = -b -> 8 = -(-8)

b = -c -> -8 = -(8)

a = c -> 8 = 8

The total percent discount offered by the merchant is 57.12%.

A discount is when the price of an items is reduced. It makes a good cheaper when a discount is applied.

The percent change in price after the first discount = 100% - 32% = 68%

The final price after the second discount = (100 - 16%) x 68%
