Step-by-step explanation:

for a triangle inscribed in a semicircle that angle is always 90 degrees

9514 1404 393

Answer:

  C.  90°

Step-by-step explanation:

A triangle inscribed in a semicircle is always a right triangle. The measure of angle Y, which subtends an arc of 180°, is half the measure of the arc it subtends, so is 180°/2 = 90°.

Answer:

x = 15

Step-by-step explanation:

75 + 10x = 225

subtract 75 from both sides

10x = 150

divide both sides by 10

x = 15

Answer:

x = 15

Step-by-step explanation:

75 +10x = 225                 Given

75-75+10x = 225-75       Subtract 75 from each side (to isolate x)

10x = 150                         After

10x/10 = 150/10               Divided each side by 10 (to get the unite rate of x)

x = 15                               Answer

Answer:

The bike will cover 250 km of distance with 5 liters of petrol.

Step-by-step explanation:

First, we have to calculate the amount of distance the bike will be able to cover in 1 liter of petrol.

[tex]\frac{150 \ km}{3 \ liters}[/tex]

[tex]= 50 \ km/liter[/tex]

Therefore, for every liter, the bike will be able to travel 50 km of distance.

Now, let's multiply the distance travelled by each liter with the total number of liters.

[tex]\frac{50 \ km}{liter} \cdot 5 \ liters[/tex]

[tex]= 250 \ km[/tex]

Finally, we have our answer: the bike will cover 250 km of distance with 5 liters of petrol.

Hope this helped!

Answer:

Step-by-step explanation:

150 / 3 = 50 km per liter sooo

5 * 50 = 250 Km

The solution to an equation is the result of solving the equation

The solution to 40 + 40 - 20 . 0 + 3 + 125 is 208

The equation is given as:

[tex]40 + 40 - 20 \cdot 0 + 3 + 125[/tex]

Evaluate the products of 20 and 0

[tex]40 + 40 - 20 \cdot 0 + 3 + 125 = 40 + 40 -0 + 3 + 125[/tex]

Add the terms of the expression

[tex]40 + 40 - 20 \cdot 0 + 3 + 125 = 208[/tex]

Hence, the solution to 40 + 40 - 20 . 0 + 3 + 125 is 208

Answer:

$ 65.13

Step-by-step explanation:

John deposits $25 at the end of each month in a savings account with 6.4% annual interest compounded monthly. What is his account balance at the end of 15 years? *

The formula for compound interest =

A = P(1 + r/n)^nt

Where

P = Initial amount deposited = $25

r = Interest rate = 6.4% = 0.064

n = number of times interest is compound = monthly = 12 times

t = time in years = 15 years

A = $25 × (1 + 0.064/12)^12 × 15

A = $65.13

His account balance at the end of 15 years is $65.13

The distance between the points is equal to 267 feet

Step-by-step explanation:

In order to find the distance between the highest and the lowest points in the park we just have to subtract the the lower height from the higher height and the resulting difference will be equal to the distance between the two points. And so we get..........

235 - (-32) = 235 + 32 = 267

(Notice that the 32 feet are written as (-32) because the lowest point is 32 feet below the sea level).

Answer:

Circle 1=6x+2y

Rectangle 4 = 3x+y

Circle 4 = 5x

Step-by-step explanation:

4x+3y and 2x-y can be added to find result for the circle.

Let C1 represent circle 1

4x+3y+2x-y=C1\\

Combining\:like\:terms\\

4x+2x+3y-y=C1

6x+2y=C1

So, The result is: C1=6x+2y

Now, We need to solve:

Let R1 represent rectangle 4

x+4y + R1 = 4x+5y

R1=4x+5y-(x+4y)

R1=4x+5y-x-4y

R1=4x-x+5y-4y

R1=3x+y

So, Solving x+4y + R1 = 4x+5y, We get R1 = 3x+y

Now, We need to solve the equation:

Let C4= Circle 4

2x-y+3x+y=C4

Combining the like terms

2x+3x-y+y=C4

5x=C4

So, Solving 2x-y+3x+y=C4 we get C4 = 5x

To find:

The value of given expression by using the Laws of Exponents.

Solution:

We have,

[tex]\left(-\dfrac{2}{3}\right)\times \left(-\dfrac{2}{3}\right)^3[/tex]

Using the Laws of Exponents, we get

[tex]=\left(-\dfrac{2}{3}\right)^{1+3}[/tex]      [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]=\left(\dfrac{-2}{3}\right)^{4}[/tex]

[tex]=\dfrac{(-2)^4}{(3)^4}[/tex]      [tex][\because \left(\dfrac{a}{b}\right)^n=\dfrac{a^n}{b^n}][/tex]

[tex]=\dfrac{(-2)\times (-2)\times (-2)\times (-2)}{(3)\times (3)\times (3)\times (3)}[/tex]

[tex]=\dfrac{16}{81}[/tex]

Therefore, the value of given expression is [tex]\dfrac{16}{81}[/tex].

Answer:

We conclude that the time required to get  a total amount of $6,880.00  from compound interest on a principal of $ 4,400.00  at an interest rate of 2.4% per year  and compounded 4 times per year  is 18 years and 8 months.

Step-by-step explanation:

We know the formula

[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]

where

Given

Total amount A = $6,880

Principle amount P = $4,400

Interest Rate r =  2.4% = 0.024 per year

Compounded quarterly = n = 4

Thus, the time period can be fetched using  the simplified-derived equation suchs as:

t = ln(A/P) / n[ln(1 + r/n)]

substituting the values

t = ln(6,880.00/4,400.00) / ( 4 × [ln(1 + 0.006/4)] )

t = 18.8 years

Therefore, we conclude that the time required to get  a total amount of $6,880.00  from compound interest on a principal of $ 4,400.00  at an interest rate of 2.4% per year  and compounded 4 times per year  is 18 years and 8 months.

Answer:

there are dots outside of the allotted area

Step-by-step explanation:

I've never taken a math help class but from your paper one can assume you have to point out the error in the graph. Its a bit fuzzy so I cant see the numbers or labels but you take what you learned for how to graph and apply it here.

For example:

The dots should stay inside the graph. Not on the outside

The numbers that are on the side, the axis, they should all progress in a specific sequence. Like 2,4,6,8,10. It needs to stay constant. Not 2,4,6,8,19

Same for both x and y axis^

I'm not sure if that helps much with what your doing seeing as the instructions apply what you've already learned, but I hope you do good!

Answer:

[(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

This can be written as the difference of 2 squares:

(a^4 - 8a^2b^2 + 16b^4) -81

= (a^2 - 4b^2)^2 - 81

=[(a^2 - 4b^2) + 9] [(a^2 - 4b^2) - 9]

= [(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

The factorized form of the given expression will be as:

[(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

Factorization, also known as factoring, is the breakdown of one element into a product of other objects, or factors, which when multiplied together generate the original. For example, the number 21 factors into primes as 3 × 7, and the polynomial x² − 9 factors as (x+3)(x-3).

The expression is given in the question as:

(a⁴ - 8a²b² + 16b⁴) - 81

We have to determine the factorized form of the given expression

As per the given question, the required solution would be as:

(a⁴ - 8a²b² + 16b⁴) - 81

This can be written as the difference between 2 squares:

⇒ (a² - 4b²)² - 81

⇒ [(a - 4b²) + 9] [(a² - 4b²) - 9]

⇒ [(a - 2b)(a + 2b) + 9)][(a - 2b)(a + 2b) - 9]

Answer:

332.5 miles

Step-by-step explanation:

let me know if its right :)

Answer:

Step-by-step explanation:

slope-intercept formula.. y= mx + b  

so that's the form we want to get to

use the point-slope formula to get there  y-y1 = m(x-x1)

m= slope and (x1,y1) is your given point

y-5 = 4(x-3.5)

y-4 = 4x - 14

y = 4x -14 +4

y = 4x -10

this looks like the slope-intercept form :)

The equation of a line with slope 4 that passes through the point (3.5,5) in slope-intercept form is y = 4x - 9 where y-intercept is -9

It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.

If in the linear equation one variable is present then the equation is known as the linear equation in one variable.

We have:

The slope of the line = 4

The line passes through a point (3.5, 5)

We know the equation of the line that has slope m and y-intercept c:

y = mx + c

y = 4x + c   (m = 3)

Point (3.5, 5) must satisfy the above line equation:

5 = 4(3.5) + c

c = -9 put this value in the line equation we get:

y = 4x -9

Thus, the equation of a line with slope 4 that passes through the point (3.5,5) in slope-intercept form is y = 4x - 9 where y-intercept is -9
