Answer:

Step-by-step explanation:

if we have a right triangle,

one angle=90

180-90=90

let x be one angle, and y another angle

the other is 2x+30

x+2x+30=90

3x=60

x=20

y=70

The measure of each acute angles are 80 degrees and 10 degrees.

The triangle is a right angle triangle. This means one of its angles is 90 degrees.

The other 2 angles sum up to 90 degrees.

An acute angle is less than 90 degrees.

The measure of one acute angle is twice the sum of the measure of the other

acute angle and 30. Therefore,

first acute angle  = x

let the other angle  = y

y = 2(x + 30)

y = 2x + 60

2x - y = -60

x + y = 90

3x = 30

x = 30 /3

x = 10 degrees

y = 90 - 10

y = 80 degrees

Answer:

5[tex]\sqrt{3}[/tex]

Step-by-step explanation:

in a 30-60-90 triangle the ratio of sides, respectively, is 1 : [tex]\sqrt{3}[/tex] : 2

you can set up a proportion like this to solve for 'x':

[tex]\sqrt{3}[/tex] / 1 = 15 / x

cross-multiply:

[tex]\sqrt{3}[/tex]x = 15

x = 15/[tex]\sqrt{3}[/tex]

rationalize the denominator by multiply top and bottom by [tex]\sqrt{3}[/tex]

you get 15[tex]\sqrt{3}[/tex] ÷ 3 which is 5[tex]\sqrt{3}[/tex]

Step-by-step explanation:

[tex] \text{3(2x + 5)}[/tex]

Answer:

Ok, Heres some facts I guess, I dont really know.

--------------------------------------------------------------------------------------------------------

As the weeks go by, Jonas learns all the colors, but still sees only glimpses of them in the world around him.

---------------------------------------------------------------------------------------------------------

Jonas is angry that the world is devoid of color; it's not fair, he says.

--------------------------------------------------------------------------------------------------------

The Giver asks him to explain. Jonas argues that without color, there aren't choices. He can't decide in the morning whether he wants to wear blue or red. He knows what color your shirt is isn't really important, but he thinks the ability to choose at all is what matters—on principle.

--------------------------------------------------------------------------------------------------------

Jonas elaborates by discussing Gabriel, whom The Giver already knows about. What if Gabriel could choose which color toy he wanted?

--------------------------------------------------------------------------------------------------------

The Giver explains that, if that were the case, then Gabriel might make the wrong choices.

--------------------------------------------------------------------------------------------------------

Jonas realizes the wisdom. He agrees that people shouldn't be allowed to choose their own spouses or jobs, because they might be wrong. "We really have to protect people," he says, "from wrong choices," because that way "it's safer."

--------------------------------------------------------------------------------------------------------

Well, that was quick. So much for Jonas the freedom-lover.

--------------------------------------------------------------------------------------------------------

Still, though, Jonas doesn't quite feel satisfied with his own conclusion. He feels frustrated.

--------------------------------------------------------------------------------------------------------

Actually, he feels angry. All the time. He's angry at his friends, for example, for being satisfied with their lives, which are so dull and not vibrant.

--------------------------------------------------------------------------------------------------------

He even tries to get Asher to see color one day, which doesn't go over so well, especially when he tries to touch Asher to make him see it. (Touching is a no-no in this community.)

Step-by-step explanation:

Here, we want to get the height of the triangle

As we can see , the whole

length is 13 cm

This is obtained by adding the length of the side of the rectangle to the height of the triangle

Thus, we have that

height = 13-7

height = 6 cm

Answer:

28734.6cm^3

Step-by-step explanation:

Given data

diameter of ball = 38cm

radius = 38/2 =  19cm

The volume of a spher= 4/3πr^3

substitute

V= 4/3*3.142*19^3

V=4/3*3.142*6859

V=4/3*21550.978

V=86203.912/3

V= 28734.6cm^3

Hence the volume of the ball is 28734.6cm^3

-21,  -23, -27, -28, -28, -29 order them least to greatest and then find the middle if there is not a middle then put -27.5 as your answer for the median. For the mean add up all the number then you should get -156 then divide it by 6 which should give you -26 for the mean.  and for the mode you should get -28 as the one that occurs the most often.

mean: -26

median: -27.5

mode: -28

Answer:

1/2

Step-by-step explanation:

there are 13 cards in each type so

heart or diamond would mean either one so 13 +13=26

26/52

1/2

TOTAL NUMBER OF HEART CARDS= 13

TOTAL NUMBER OF DIAMOND CARDS= 13

PROBABILITY OF AN EVENT

= NUMBER OF FAVOURABLE OUTCOMES

TOTAL NUMBER OF POSSIBLE OUTCOMES

Probability of getting a heart card♥=13/52 =1/4

Probability of getting a DIAMOND card♦= 13/52 =1/4

Probability of getting a heart and a diamond card =26/52 =1/2

I hope you got it!!!...right!!
