Answer:

Her proportion does not have corresponding parts in the same position.

Step-by-step explanation:

Sharon is drawing up a plan for building a reduced Eiffel Tower on her backyard patio. She has room to make a base of 5 feet. Her work is shown below.

What was Sharon’s error in finding the missing height measurement for her reduced tower?

Her proportion does not have corresponding parts in the same position.

For cross products, she needed to multiply 1050(328) and 5(x).

She needed to divide both sides by 1640, instead of 1050.

She needed to round down to 1.5 feet.

Height : base = 1,050 : 328

She has room to make a base of 5 feet.

Height : base = x : 5

1,050 : 328 = x : 5

1,050 / 328 = x / 5

Cross product

1,050 * 5 = 328 * x

5,250 = 328x

Divide both sides by 328

x = 5250 / 328

= 16.006

Approximately 16

Step-by-step explanation:

The required amount of flour will be 12 cups of flour in the recipe.

The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.

A recipe requires for 2 parts sugar to 3 parts flour. 8 cups of sugar are used which is given in the question.  

Let the number of cups of flour would be x,

According to the given question, the required ratio would be as

2 parts sugar : 3 parts flour = 8 cups of sugar : x cups of flour

2 / 3 = 8 / x

2x  = 24

x = 24/ 2

Apply the division operation,

x = 12

Therefore, the required amount of flour will be 12 cups of flour in the recipe.

Answer:

Check the explanation.

Step-by-step explanation:

As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.

As the slop-intercept form is given by:

[tex]y = mx+b[/tex]

where m is the slope and b is the y-intercept.

substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.

[tex]y = mx+b[/tex]

[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]

[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]

[tex]-5+b=-10[/tex]

[tex]-5+b+5=-10+5[/tex]

[tex]b=-5[/tex]

And the equation of the line in the slope-intercept form will be:

[tex]y = mx+b[/tex]

putting b = -5 and slope = m = 5/2

[tex]y = mx+b[/tex]

[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]

[tex]y=\frac{5}{2}x-5[/tex]

Determining the zero of function.

As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.

so let us determine the value of x (zero of function) by setting y = 0.

[tex]0=\frac{5}{2}x-5[/tex]

[tex]\frac{5}{2}x-5=0[/tex]

[tex]\frac{5}{2}x=5[/tex]

[tex]5x=10[/tex]

[tex]x=2[/tex]

Therefore, the zeros of the function will be:

Answer

I guess the best way to learn algebra is first being confident with your arithmetic and PEMDAS/BODMAS, then understanding how substitution works, knowing what like-terms, binomial products, squares, etc are and going through worked examples as well as solving algebraic problems yourself. Of course, to get a grasp on algebra, you should start from the basics and continue working your way up. You should be able to find resources online to help you.

Good luck!

Answer:

A. 9 Desserts

Step-by-step explanation:

We can make the equation 2/3x = 6 to find the answer

2/3x = 6 we need to isolate x so we divide by 2/3 on both sides

2/3 / 2/3 = 1 and 6 / 2/3

we divide 6 by 2/3 like 6/1 * 3/2 = 9

x = 9

Answer:1.) I chose coin A and B

2.) Coin: B Value: $40 Annual rate: %5

Coin: A Value: $25 Annual rate: %7

3.) Coin: A P: 25 R: 1.07 Function: v = 25(1.07)^t

Coin: B P: 40 R: 1.05 Function: v = 40(1.05)^t

4.) Base: 1+r Initial: P Exponent: t

If R increased, then P would also increase because you must distribute, and you would be distributing R into P there for if R changes then so would P.

5.) Coin A: Initial value: $25 10 years: $25.70 20 Years: $26.40 30 years: $27.10 60 years: $29.20

Coin B: Initial value: $40 10 years: $40.50 20 years: $41 30 years: $41.50 60 years: $43

Coin C: Initial value: $60 10 years: $60.40 20 years: $60.80 30 years: $61.50 60 years: $62.40

6.) Coin A because the value goes up the most and I probably wouldn't be able to keep the coin for more than 60 years because I would lose it.

Step-by-step explanation:

i did it

I also chose coin A and coin B. You can choose any two coins you want, but the answers would turn out different so I recommend using A and B.

Answer:

2.      

Coin: A                     Current value: $25                     Appriciation rate: 7%

Coin: B                     Current value: $25                     Appriciation rate: 5%

3.

Coin: A               P: 25                  R: 0.07                 V(t) = 25(1+0.07)^t

Coin: B               P: 40                  R: 0.05                 V(t) = 40(1+0.05)^t

4.a

Base: 1+R

Constant or initial value: P

Exponent: T

4.b

No, the initial value would not increase, although, by changing the rate would increase the growth.

5.

Value:          25                            

10 years:      V(t) = 25(1.07)^10   -   $49.18

See explaination

Step-by-step explanation:

5.

So when the value is 25, we use the formula from question 3 ( V(t) = 25(1.07)^10 ) and solve

Continue to use the same formula to answer the other numbers of years, only change the exponent, ^10, to the number of years.

For example:  20 years = ^20                 30 years = ^30 and so on.

Also, this is the correct answer to number 5. I got an A on this assignment

Answer:

  43

Step-by-step explanation:

x° is common to both the smaller and the larger triangle, which means the sum of the two other angles will be the same in the two triangles:

  76° +49° = y° +81°

  124° -81° = y° = 43° . . . . . subtract 81°

Answer:

The answer is "Through which we can infer that perhaps the ABC triangles is obstinate shaped".

Step-by-step explanation:

Paul draws that ABC as well as the Median triangle from and A and B nodes. If the median passes after a certain point, and his marks the point X. Paul now says point X (i.e., a triangle's center) is outside the ABC triangle.  

They may also conclude that perhaps the ABC triangle does have an obtuse angle because the centroid is in the ring in case of even a severe triangle, that centroid is already on the right triangle in case of the triangle and cases of an obtuse-angled rectangle, the angular velocity is an outside ring.

Answer:

Step-by-step explanation:

From the given information:

Let X represent the amount of the stock that goes up in the first period; &

Let Y denote the cumulative amount that goes up in the first three periods.

Then,

[tex]X= X_1 + X_2 \\ \\ \\EX= EX_1 +EX_2\\ \\\\Now ; EX = 0 \\ \\ EX = \dfrac{1}{2}\times 1 + \dfrac{1}{2}\times -1 \\ \\ EX = \dfrac{1}{2}-\dfrac{1}{2} \\ \\ EX = 0[/tex]

[tex]Cov(x,y) = Var(X_1) +Var(X_2) \\ \\ =\dfrac{1}{2}(1+1) + \dfrac{1}{2}(1+1) \\ \\ = \dfrac{1}{2}(2)+ \dfrac{1}{2}(2) \\ \\ = 1+1 \\ \\ =2[/tex]

[tex]Var (X) = Var (X_1+X_2)\\ \\ = 2 \ Var(X_1) \\ \\ = 2 \times (1) \\ \\ = 2[/tex]

[tex]Var (Y) = Var (X_1 +X_2+X_3) \\ \\ = 3 \times Var(X_1) = \\ \\ = 3 \times 1\\ \\ = 3[/tex]

∴

[tex]Corr(x,y) = \dfrac{2}{\sqrt{6}} \\ \\ = \dfrac{2}{\sqrt{2\times 3}} \\ \\= \sqrt{\dfrac{2}{3}}[/tex]

Answer:

AB=5.6

Step-by-step explanation:

Answer:

AB ≈ 5.6 cm

Step-by-step explanation:

Using the cosine ratio in the right triangle, that is

cos62° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{AB}{12}[/tex] ( multiply both sides by 12 )

12 × cos62° = AB , then

AB ≈ 5.6 cm ( to 1 dec. place )

Answer:

x = 76°

y = 128°

z = 16°

Step-by-step explanation:

JKLM is a cyclic quadrilateral.

Opposite angles of a cyclic quadrilateral are supplementary.

Therefore,

x + 104° = 180°

x = 180° - 104°

[tex] \huge \red {\boxed {x = 76\degree}} [/tex]

y + 52° = 180°

y = 180° - 52°

[tex] \huge \purple {\boxed {y = 128\degree}} [/tex]

By inscribed angle theorem:

[tex] 88\degree + z = 2\times 52\degree \\\\

88\degree + z = 104\degree \\\\

z = 104\degree - 88\degree \\\\

The term rule will be:

[tex]a_n=n+21[/tex]

Step-by-step explanation:

Given the sequence

[tex]22, 23, 24, 25, ...[/tex]

Computing the common difference of all the adjacent terms

[tex]22,\:23,\:24,\:25[/tex]

[tex]23-22=1,\:\quad \:24-23=1,\:\quad \:25-24=1[/tex]

As the difference between all the adjacent terms is the same and equal to

[tex]d=1[/tex]

The first element of the sequence

[tex]a_1=22[/tex]

We know that  An Arithmetic sequence has a constant difference 'd' and is defined by

[tex]a_n=a_1+\left(n-1\right)d[/tex]

substituting [tex]a_1=22[/tex], and [tex]d=1[/tex] in the nth term to get the term rule

[tex]a_n=a_1+\left(n-1\right)d[/tex]

[tex]a_n=\left(n-1\right)+22[/tex]

[tex]a_n=n+21[/tex]

Therefore, the term rule will be:

[tex]a_n=n+21[/tex]
