Answer: Masha needs 40 more minutes to complete the path.

Step-by-step explanation:

So if Dina is cycling speed is 10km per hour that means it will take Dina 2 hours to completed the the path.

Here;   [tex]\frac{10km}{1h}[/tex] = [tex]\frac{20km}{x }[/tex]  

           10x = 20

       x= 2  

But since Masha still have 4 more km to go  you will add 20 + 4 =24

[tex]\frac{10}{1}[/tex] = [tex]\frac{24}{x}[/tex]

10x= 24

x= 2.4

Answer:c

Step-by-step explanation:

Given

Two points are given [tex](9,-2)[/tex] and [tex](6,3)[/tex]

We know distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Distance [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Substituting values we get

[tex]d=\sqrt{(6-9)^2+(3-(2))^2}[/tex]

[tex]d=\sqrt{(-3)^2+(5)^2}[/tex]

[tex]d=\sqrt{9+25}[/tex]

[tex]d=\sqrt{36}[/tex]

[tex]d=6\ units[/tex]

First compute the component form of vector u by subtracting its initial values from terminal values. 18-1=17, 6-(-12)=18. So u=(17, 18). Since v points in the opposite direction, and has a magnitude three times that of u, we multuply the u by -3 and get v=(-3*17, -3*18)=(-51, -54).

Answer:

91.46m

Step-by-step explanation:

The length of 100 yard football field in meters.

From the dimension given,

1 yard = 3 feet

Therefore,

100 yard = x feet

1 yard = 3 feet

100 yard = x feet

X = (100 × 3) / 1

X = 300 feet.

But,

1 metre = 3.28feet

X metre = 300 feet

X = (300 × 1) / 3.28

X = 91.46m

Therefore, 100 yard football field is equal to 91.46m

Answer:

The student was supposed to multiply 4(1+5n)  to equal 4+20n instead she forgot to multiply 5n and put 4+5n.

Step-by-step explanation:

-8n + 4(1 + 5n) = -6n -14

-8n + 4 + 20n = -6n -14

12n+4 = -6n -14

+6n       +6n

18n +4 = -14

       -4    -4

      18n= -18

Answer:

9 = n

Step-by-step explanation:

12 = 6(n – 7)

Divide by 6 on both sides

12/6 = 6/6(n – 7)

2 = n-7

Add 7 to each side

2+7 = n-7+7

9 = n

Answer:

9 = n

Step-by-step explanation:

12 = 6(n – 7)

12 = 6n - 42. Use the distributive property

12 = 6n - 42

+42. +42. Inverse operations

54 = 6n

÷6. ÷6

9 = n

Answer: $184.50

Step-by-step explanation:

Eric’s income puts him in the second tax bracket which has 15%, tax rate.

Eric has the following income-

Income from dividends = $515 what ch is (taxed at 15%)

Therefore; tax on dividend income = $515 * 15%

= $515 × 15/100

= $515 × 0.15

= $77.25

The Income from municipal bonds = $65 (Not taxed)

The income from sales of stock (capital gain)= $915 - $200 = $715 (This is held for less than 1 year therefore it is taxed as ordinary income at 15% tax rate)

Therefore,the tax on the short-term capital gain

= $715 * 15%

= $715 × 0.15

= $107.25

Therefore the total amount Eric will pay in taxes on last year’s investment will be:

= tax on dividend income + the tax on short-term capital gain

= $77.25 + $107.25

=$184.50

Answer:

$107.25

Answer:

a1 = -7

d = -10

Step-by-step explanation:

Look at the points, you first point (1,-7) where a1 is 1 and that also means -7

Same for d go to the second point (2,-17) now add a1 from that

-17+7 = -10 so to get from -7 to -17 you had to add -10 <--- that is your d!

Goodluck

a1  is  -7 and d is -10. Comparative genomics use bidirected graphs known as sequence graphs.

Comparative genomics use bidirected graphs known as sequence graphs, often referred to as alignment graphs, breakpoint graphs, or adjacency graphs. The structure is made up of several graphs or genomes, where the edges and vertices correspond to the adjacencies.

A sequence, which often represents an entire genome or a portion of a genome, is produced by traversing an interdependent component of segments with adjacency edges (referred to as a thread).

first point (1,-7) where a1=1 and that also means -7

second point (2,-17) now add a1 from that

-17+7 = -10 so to get from -7 to -17 you had to add -10, its d

a1 = -7

d = -10

Therefore, a1  is -7 and d is -10.

Answer:

$2,980

Step-by-step explanation:

Mortgage points is a term used by a mortgage brokers and it is usually referred to the percentage of the loan amount.

From the given question:

Felicia decided to purchase 2 points in order to lower her interest rate on her $149,000 mortgage

the 2 points that Felicia purchased is equivalent to 2% i.e 0.02 points

Thus; the additional money  she need to bring to closing is calculated by the formula:

cost = points × loan amount

= 0.02 × $149,000

= $2,980

Answer:

a. 14.19 feet

b.  2504.26 cubic foot.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.  

(a) Determine the height of the cone to the nearest tenth of a foot.

(b) Determine the overall volume of the tower to the nearest cubic foot.

Please have a look at the attached photo.  

My answer:

Given the information:

The cylinder has:

The cone has:  an inclination angle of 25 degrees

(a) Determine the height of the cone to the nearest tenth of a foot.

Let h is the height of the cone

The distance from C to A is 6 feet and the measure of the angle CAB is 25 degrees. The triangle ABC is a right triangle.

=> sin(CAB) = [tex]\frac{CA}{h}[/tex]

<=> h = [tex]\frac{CA}{sin25}[/tex]

<=> h = [tex]\frac{6}{sin25}[/tex]

<=> h = 14.19 feet

(b) Determine the overall volume of the tower to the nearest cubic foot.

overall volume = volume of the cone + volume of the cylinder

We have:

= 15*[tex]r^{2}[/tex]*π

= 15*[tex]6^{2}[/tex]*π

= 1696.6 cubic foot.

= 1/3*14.19*[tex]6^{2}[/tex]*π

= 534.76 cubic foot.

=> overall volume =  534.76 + 1696.6 = 2504.26 cubic foot.

Hope it will find you well.
