Answer:

0.7

Step-by-step explanation:

zero and seven TENths. the place value of the 7 is tenths so on the bottom of the fraction will be 10. i'm bad at explaining so sorry.

the decimal equivalent of 7 / 10 is 0.7.

To find the decimal equivalent of 7 / 10, we divide the numerator ( 7) by the denominator ( 10).

When we perform the division, 7 ÷ 10, we get 0.7.

Therefore, the decimal equivalent of 7 / 10 is 0.7.

In decimal form, the number 0.7 represents 7 tenths or 7 parts out of 10. It indicates that the numerator ( 7) is 7 / 10th of the denominator ( 10). This decimal representation makes it easier to compare the fraction with other decimal numbers and perform arithmetic operations using decimals.

Answer:

The distance between the two is 465 meters

Step-by-step explanation:

We first need to set up a triangle that shows the relative position and distances of the two friends

Please check attachment for this

To get this distance, which represents the hypotenuse of the triangle, we make use of Pythagoras’ theorem

Mathematically;

Pythagoras’ theorem states that the square of the hypotenuse equals the sum of the squares of the two other sides

Thus;

D^2 = 256^2 + 388^2

D^2 = 216,080

D = √216,080

D = 464.84 which is approximately 465 m

Answer:

(1+cos(theta))/(1-sin^2(theta))=sec(theta)+tan^2(theta)+1

(1+cos(theta))/cos^2(theta)=sec(theta)+sec^2(theta)-1+1

(1-cos(theta))/cos^2(theta)=1/cos(theta)+1/cos^2(theta)

1-cos(theta)=cos(theta)+1

2cos(theta)=0

cos(theta)=0

theta=pi/2 and 3pi/2

I don't fully understand your question but it's quite easy to solve. As shown above, option (2) is good and you can factor the RHS but I would find it rather trivial when you can multiply both sides by cos^2(theta) just as easily. I hope this helps you.

Answer:

[tex]y+1=\frac{-2}{3} (x+4)[/tex]

Step-by-step explanation:

you can use the equation point-slope of a line

(y-y1)= m(x-x1)

m is the slope =rise /run

to get from the lower point  on the line to the other you rise 4 units and run -6 units so m= -4/6= -2/3

now that you have the slope pick you need one point

pick any poin on the line for example (-4, -1)

now you substitute into the point-slope equation point (-4,-1) and slope -2/3

(y+1)= -2/3(x+4)

in standard form will be

y=[tex]\frac{-2x}{3} -\frac{2*4}{3} -1[/tex]

y=[tex]\frac{-2x}{3}- \frac{5}{3}[/tex]

Answer:

Step-by-step explanation:

Slope can be calculated by:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

We know M, y1, x2, and x1. We want to calculate for y2

[tex]\frac{f-7}{-8-(-9)} = 3\\\frac{f-7}{1} = 3\\f-7 = 3\\f = 10\\[/tex]

Answer: f = 10

Step-by-step explanation: Start with the slope formula.

m = y₂ - y₁ / x₂ - x₁

Plugging the given information into the

slope formula, we get 3 = 7 - f / -9 - (-8).

This simplifies to 3 = 7 - f / -1.

Multiply both sides of the equation by -1 to get -3 = 7 - f.

Solving from here, you be should be able to easily find that 10 = f.

Remember, it's very easy to check your

answer to these kinds of problems.

Since 10 = f, you can plug a 10 back in for f in the original problem.

Then check to see if the line that passes through the points

(-8, 10) and (-9, 7) really does have a slope of 3.

Step-by-step explanation:

Savings accounts offer interest payments on them however they are quite easy to access which means that banks are limited in being able to use funds in savings accounts for long term loans which bring in revenue.

This therefore translates to lower interest rates being paid on the accounts and in 2017 up until now, a competitive and realistic interest rate often found in savings accounts is approximately 1%.

Step-by-step explanation: Because its 3 more a week and week is x and plus the 5 you already have

The rule mode for the total number of fish as the function of the number of weeks will be equal to y = 3x + 5. Hence, option A is correct.

Equations are mathematical expressions that have two algebra on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.

As per the given information in the question,

Number of Discus fish Andy have = 5

Each week Purchase = 3

Then, the equation will be,

y = 3x + 5

Here, y is the total number of discus fish and x is the number of weeks.

Step-by-step explanation:

Given:

Initial value of car = 20,000

Depreciation or decreasing rate = 10% = 0.10

To find:

The equation that gives the value of the car.

Solution:

It is given that the value then depreciates or decreases by 10% of in initial value each year. It means the depreciation value is same for each year, i.e., 10% of initial value.

[tex]10%\text{ of }20000=\dfrac{10}{100}\times 20000[/tex]

[tex]10%\text{ of }20000=2000[/tex]

So, the value of car decreased by 2000 per year.

Let y be the value of can after x years.

Then, the value decreased in x years is 2000x.

So, the values of the car is

[tex]y=20000-2000x[/tex]

Therefore, the required equation is [tex]y=20000-2000x[/tex].

Answer:

34 km/h

Step-by-step explanation:

speed = distance/time

Distance = 17km

Time = 0.5 or 1/2 hours because it's 30 minutes between 17:15 to 17:45, and 30 minutes is a half of an hour and you want km over hours

So

speed = 17/0.5

speed = 34 km/h
