Si en un triángulo un ángulo mide 30º y otro 70º¿cuánto mide el tercer ángulo?

Answers

Answer 1

Answer:

El tercer ángulo es 80

Step-by-step explanation:

En un triángulo hay 3 ángulos. Cuando sumas todos los ángulos, es igual a 180. Entonces, para esto, todo lo que tienes que hacer es sumar 30 y 70, lo que te da 100. Luego, restar 100 de 180, lo que te da 80. Lo que significa que el tercer ángulo es 80 :)

number.​

Answers

Answer:

let the number be x

thrice of the number=3x

one-half of the number=(1/2)x

so from the expression we:

3x-x/2=2500

(6x-x)/2=2500

6x-x=2*2500

5x=5000

x=5000/5

285 divided by 45

Which is true about this division problem? Select all that apply.
45 goes into 285 evenly.
45 does not go into 285 evenly.
The quotient contains a repeating decimal.
The quotient contains a terminating decimal.
The quotient is 6.ModifyingAbove 3 with bar.
The quotient is 6.3.

Answers

Answer:

Step-by-step explanation:

The true statements are:

45 does not go into 285 evenly.

The quotient is 6 with a remainder of 15.

Here,

To divide 285 by 45, we perform the division:

  6

-------

45 | 285

  - 270

  -------

     15

The quotient is 6 with a remainder of 15.

Now, let's analyze the statements:

45 goes into 285 evenly. - False.

45 does not divide 285 evenly since there is a remainder of 15.

45 does not go into 285 evenly. - True.

As explained above, 45 does not divide 285 evenly, and there is a remainder of 15.

The quotient contains a repeating decimal. - False.

There is no repeating decimal in the quotient since the division is a whole number (6).

The quotient contains a terminating decimal. - False.

As mentioned earlier, there are no decimals involved in the quotient; it's a whole number.

The quotient is 6 with a bar above 3. - False.

The quotient is 6 with a remainder of 15, not 6.3.

In summary, the true statements are:

45 does not go into 285 evenly.

The quotient is 6 with a remainder of 15.

Answers

Answer:

a) How tall would the sunflower be after 10 weeks?

35 inches tall

Step-by-step explanation:

At the beginning of spring, Jeremiah planted a small sunflower in his backyard. When it was first planted, the sunflower was 15 inches tall. The sunflower then began to grow at a rate of 2 inches per week.

If the rate:

1 week = 2 inches

10 weeks = x inches

x = 10 × 2/1

x = 20 inches

How tall would the sunflower be after 10 weeks?

The initial height = 15 Inches

The height after 10 weeks =

15 inches + 20 inches

= 35 inches

Maya will deposit $1,650 in an account that earns 5% simple interest every year. Her brother, James, will deposit $1,600 in an account that earns 8% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Compare and contrast the two siblings' accounts after four year

Answers

Answer:

Step-by-step explanation:

Step one:

given data

Maya

P=$1650

r=5%= 0.05

t= 4 years

The simple interest expression is

A=P(1+rt)

A=1650(1+0.08*4)

A=1650(1+0.32)

A=1650(1.32)

A=1650*1.32

A=$2178

James

P=$1600

r=8%= 0.08

t=4years

The compound interest expression is

A=P(1+r)^t

A=1600(1+0.08)^4

A=1600(1.08)^4

A=1600*1.360

A=$2176

After 4 years Mayas' balance is $2178

After 4 years James' balance is $2176

the difference is =2178-2176=$2

Each year, Andrea donates a total of $800 for scholarships at her local community college. This year, she wants the amount she donates for liberal arts to be three

times the amount she donates for scholarships for business. Determine the amount she will donate for each type of scholarship.

The equation is Andrea will donate $ for business scholarships and $ for liberal arts scholarships.

Answers

Answer:

The equation is [tex]L + B = \$800[/tex]

Andrea will donate $200 for business scholarships and $600 for liberal arts scholarships.

Step-by-step explanation:

Given

Represent Liberal Arts with L and Business with B

From the question, we have that:

[tex]L = 3 * B[/tex]

and

[tex]Total = \$800[/tex]

Required

Determine how much she donates for each

The total L + B is 800

i.e.

[tex]L + B = \$800[/tex]

Substitute 3 * B for L

[tex]3 * B + B = \$800[/tex]

[tex]3 B + B = \$800[/tex]

[tex]4B = \$800[/tex]

Solve for B

[tex]B =\$800/4[/tex]

[tex]B =\$200[/tex]

Recall that :

[tex]L = 3 * B[/tex]

[tex]L = 3 * \$200[/tex]

[tex]L = \$600[/tex]

GEOMETRY

Answers

Answer:

  ZV ≈ 42.8

Step-by-step explanation:

WZ and ZX and ZY are each radii of the incircle, so are the same length.

  8x -22 = 3x +8

  5x = 30

  x = 6

  ZX = ZY = 3x +8 = 3(6) +8 = 26

ZV is the hypotenuse of right triangle ZVY, which has side lengths of 34 and 26. So, the length of ZV can be found from the Pythagorean theorem as ...

  ZV = √(34² +26²) = √1832

Answer:

8 < x < 16

Step-by-step explanation:

Consider an angle slightly less than 180 between the 4 and 12 ft sides.  The measure between the 2 end points is slightly less than the total of the two sides.  So the greatest length is 16.

Consider an angle slightly more than 0 between the 4 and 12 ft sides.  The measure between the 2 end points is slightly more than the difference between the two sides.  So the lowest length is 8.
