Answer:

x = 48°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

x = 180° - (90 + 42)° = 180° - 132° = 48°

Find the distance between the points (1, 7) and (10, 1)<br> Please help:)

klio [65]

Answer:

<em>The distance between the points (1, 7) and (10, 1) is 10.82 units</em>

Step-by-step explanation:

<u>Distance between two points </u>

The distance between points A(x,y) B(w,z) can be calculated with the formula:

$d=\sqrt{(z-y)^2+(w-x)^2}$

We are given the points (1,7) and (10,1), let's use their values and compute the required distance:

$d=\sqrt{(1-7)^2+(10-1)^2}$

$d=\sqrt{(-6)^2+(9)^2}$

$d=\sqrt{36+81}=\sqrt{117}\approx 10.82$

The distance between the points (1, 7) and (10, 1) is 10.82 units

A bag contains 150 marbles. Some are blue, and the rest are white. There are 21 blue marbles for every 4 white marbles. How many

Olin [163]

Given:

Total number of marbles in the bag = 150

There are 21 blue marbles for every 4 white marbles.

To find:

The number of blue marbles in the bag.

Solution:

Since, there are 21 blue marbles for every 4 white marbles, therefore the ratio of blue marble to white marbles is 21:4.

Let the number of blue marbles be 21x and white marbles be 4x.

Total number of marbles in the bag = 150

$21x+4x=150$

$25x=150$

Divide both sides by 25.

$x=\dfrac{150}{25}$

$x=6$

Now,

$\text{Blue marbles}=21x$

$\text{Blue marbles}=21(6)$

$\text{Blue marbles}=126$

Therefore, the number of blue marbles is 126.

What is the future amount of 12,000 invested for 5 years at 14% compounded monthly?

Triss [41]

The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest.

<h3 /><h3>what is compound interest?</h3>

To begin, change R from a percentage to a decimal, using the formula:

r = R/100 r = 14/100

r = 0.14 rate per year;

Next, find A by solving

A = P(1 + r/n)nt A = 12,000.00(1 + 0.14/12)(12). (5)

A = 12,000.00(1 + 0.011666666666667)(60) (60)

A = $24,067.32

Summary: The total amount accrued, principal plus interest, with compound interest on a principal of $12,000.00 at a rate of 14% per year compounded 12 times per year over 5 years is $24,067.32.

The amount of the initial loan, or principal, is multiplied by one plus the annual interest rate raised to the number of compound periods minus one to determine compound interest. You will then be left with the loan balance plus compound interest.

8x^2+23=823<br><br> whats going to be the answer I got 0 am I right?

Naily [24]

1) No; you are incorrect. "0" is NOT a solution.

Plug in "0" for "x" ;

8*0² + 23 =? 823? ;

8*0 + 23 =? 823? ;

0 + 23 = ? 823 ? ; No! ; "0 + 23 = 23 " ; NOT "823" .
_________________________________________________
2) The answers: x = 10, -10 ; or, write as: x = ± 10 .
_________________________________________________

To solve:

GIven: 8x² + 23 = 823 ;

Subtract "23" from EACH SIDE of the equation:
_____________________________________________
8x² + 23 - 23 = 823 - 23 ;
to get:
8x² = 800 ;

Now, divide EACH SIDE of the equation by "8" ;

8x² / 8 = 800 / 8 ;

to get: x² = 100 ;

Take the "square root" of EACH SIDE of the equation; to isolate "x" on one side of the equation; and to solve for "x" ;

√(x²) = √(100) ;

x = <span>± 10 .

The answers: x = 10, -10 ; or, write as: x = </span><span>± 10 .
