Answer:
4x + 7y = 14
Step-by-step explanation:
The equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
Given
y = - [tex]\frac{4}{7}[/tex] x + 2 ( multiply through by 7 to clear the fraction )
7y = - 4x + 14 ( add 4x to both sides )
4x + 7y = 14 ← in standard form

Dina and Masha start cycling on a 20 km bike path at the same time. When Dina reaches the end of the path, Masha still has 4 km of the path left to cycle. If Dina’s cycling speed is 10 km/h, how much time longer will Masha need to complete the path?
I WILL AWARD BRAINLIEST
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

Find the length of a 100-yard football field in meters. Use 1 yard = 3 feet
and 1 meter = 3.28 feet. Round to the nearest tenth.
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

A water tower in New York City has the shape of a cylinder with a cone on top. The cylinder has a diameter of 12 feet and a height of 15 feet. The roof has an inclination angle of 25 degrees
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:
diameter of 12 feet => the radius : 6 feetheight of 15 feetThe 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:
Volume of the cylinder = the height*the base area= 15*[tex]r^{2}[/tex]*π
= 15*[tex]6^{2}[/tex]*π
= 1696.6 cubic foot.
volume of the cone = 1/3*the height*the base area= 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.

Would simplifying affect the inequality?
3x < 7+3
What would be the simplified form or the next step?
Answer yes or no, simplified form written
Answer:
Simplifying would not affect the inequality, because you are still saying the same thing just in a different way
Step-by-step explanation:
the next thing you would have to do would be to add 7+3 which gives you 10 and then divided 3x by 3x and 10 by 3x and badaboom there's your answer
Vector v has its initial point at (13, -7) and its terminal point at (3, -1). Write the vector in component form and find its magnitude. Round the vector’s magnitude to the nearest hundredth unit. Make sure to show all work and explain the steps.
Is this what your looking for?
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).
12 = 6(n – 7)
Solve 2 -step equation
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:
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.
What is sequence graph?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.

Eric's income puts him in the second tax bracket (15%) last year. During the same year, he earned $515 in dividends and $65 in coupons on a municipal bond. In March, he purchased a common stock for $200. He sold the same stock six months later for $915. What is the total Eric will pay in taxes on last year's investments?
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: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]

Felicia decided to purchase 2 points in order to lower her interest rate on her $149,000 mortgage. How much additional money does she need to bring to closing
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
