Find The Length Of IR Using The Special Right Triangles

Answers

Answer 1

Answer:

7

Step-by-step explanation:

This is a 30-60-90 triangle. The side that include the 60 degree angle and the 90 degree symbol side length is half of the hypotenuse. The hypotenuse is 14 so IR is 7.

h(t)=-10x+6 h(?)=-44

Answers

Answer: h(5)=-44

Step-by-step explanation:

Given

h(t)=-10x+6

h(?)=-44

Substitute the [-44] value to the first equation

-44=-10x+6

Subtract 6 on both sides

-44-6=-10x+6-6

-50=-10x

Divide -10 on both sides

-50/-10=-10x/-10

x=5

Answers

Answer:

Answer: B, 6/11

Step-by-step explanation:

Well we know that 3+2+1=6+3=9.

So that means we will add the 2 brown crayons to the denominator.

The denominator before we added 2 to it, it was 9 as a common denominator. If we want to get the common numerator we are going to have to add the top and that will become 9 then you will have to subtract that by 3

6/11 is also the smallest number that you can get.

You can turn the fraction into a decimal and have it that way to make it easier.

When you turn a fraction into a decimal the number is always the same but with comparing numbers it is a lot easier to do than comparing fractions

Hope this helps, and if it did I would appreciate it if you marked me as Brainllest. Have a wonderful day!

2(2x + 3) = -6(x + 9)

Answers

Answer:

Your answer is -6.

Step-by-step explanation:

Simplify 2(2x+3) to get 4x+6  

Then simplify -6(x+9) to get -6x-54

Now you have 4x+6=-6x-54

Move all of the coefficients to one side:

10x+6=-54

Move all of the constants to the other side:

10x=-60

Divide each side by 10:

10/10x=-60/10

To get your answer of -6.

What is ratio of two quantities?

Suppose that we've got two quantities with measurements as 'a' and 'b'

Then, their ratio(ratio of a to b) a:b or [tex]\dfrac{a}{b}[/tex]

We usually cancel out the common factors from both the numerator and the denominator of the fraction we obtained. Numerator is the upper quantity in the fraction and denominator is the lower quantity in the fraction).

Suppose that we've got a = 6, and b= 4, then:

[tex]a:b = 6:2 = \dfrac{6}{2} = \dfrac{2 \times 3}{2 \times 1} = \dfrac{3}{1} = 3\\or\\a : b = 3 : 1 = 3/1 = 3[/tex]

Remember that the ratio should always be taken of quantities with same unit of measurement. Also, ratio is a unitless(no units) quantity.

Same thing happens for 3 quantities and more such quantities.

So if its given that Oli, Sam, and Tim's share (total  £360) are in the ratio 3:2:1, that means some common factor (lets call it 'x') must be cancelled off as 3+2+1 don't equate to 360.

So, we have:

Oli's share = 3xSam's share = 2xTim's share = 1x = x

Their total evaluates to 360 (in euros).

(we don't write symbols like of currency generally, and understand it from context. Also, sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Thus, we get:

[tex]3x + 2x + x = 360\\(3+2+1)x = 360\\6x = 360\\\\\text{Dividing both the sides by 6}\\\\\dfrac{6x}{6} = \dfrac{360}{6}\\\\x = 60[/tex]

Thus, we get:

Oli's share = 3x = 3×(60) = £180Sam's share = 2x = 2×(60) = £120Tim's share = 1x = x = £60

Thus, the amount that Sam get (the share of Sam) is £120

rename 1/2 and 2/3 as fractions with denominators of 6.then add the renamed fractions. write the sum as a mixed number.

Answers

Answer:

1 and 1/6

Step-by-step explanation:

To rename a fraction you multiply both numbers by however many times the original denominator goes into the new one.

2 goes into 6 three times.

1 times 3 is 3

and 2 times 3 is 6

so 1/2=3/6

3 goes into 6 twice

2 times 2 is 4

and 2 times 3 is 6

so 2/3=4/6

to add fractions you add the numerators while keeping the denominators the same.

3+4=7 so:

3/6+4/6=7/6

6/6=1

so 7/6 contains 1 whole

once you take that out you have 1/6 left over

a solid metal cone with radius of base 12 cm and height 24 cm is melted to form spherical solid balls of diameter 6 cm each. Find the number of the balls thus formed​

Answers

Answer:

32 solid balls are formed.

Step-by-step explanation:

Let suppose that volume of the cone is equal to the total volume of balls, of which we derive the following formula:

[tex]\frac{1}{3}\cdot \pi\cdot R^{2}\cdot h = \frac{1}{6}\cdot \pi \cdot n \cdot D^{3}[/tex] (1)

Where:

[tex]R[/tex] - Radius of the base of cone, measured in centimeters.

[tex]h[/tex] - Height of cone, measured in centimeters.

[tex]D[/tex] - Diameter of sphere, measured in centimeters.

[tex]n[/tex] - Number of balls, no unit.

Then, we clear the number of balls:

[tex]2\cdot R^{2}\cdot h = n\cdot D^{3}[/tex]

[tex]n = \frac{2\cdot R^{2}\cdot h}{D^{3}}[/tex]

If we know that [tex]R = 12\,cm[/tex], [tex]h = 24\,cm[/tex] and [tex]D = 6\,cm[/tex], then the number of balls is:

[tex]n = \frac{2\cdot (12\,cm)^{2}\cdot (24\,cm)}{(6\,cm)^{3}}[/tex]

[tex]n = 32[/tex]

32 solid balls are formed.

Answers

Answer:

x = 55

Step-by-step explanation:

ABCD is a paralellogram, m∠ABC = 2x + 15, m∠BCD = x

m∠ABC + m∠BCD = 180° (same side interior angles)

2x + 15 + x = 180

3x + 15 = 180 -15

3x = 165

x = 55

In the ​triangle XYZ​, the measure of ​∠XYZ​ is 104°, and the measure of ∠YZX is 19°. What is the measure of ∠ZXY?

Answers

Answer:

∠ZXY = 57°

Step-by-step explanation:

According to angle sum property of a triangle, sum of all the angles of the triangle is [tex]180[/tex]°.

In ΔXYZ,

∠XYZ + ∠YZX + ∠ZXY = 180°

Put ∠XYZ = 104°, ∠YZX = 19°

104° + 19° + ∠ZXY = 180°

123° + ∠ZXY = 180°

∠ZXY = 180° - 123°

∠ZXY = 57°

Therefore,

∠ZXY = 57°

Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

x = 180 - 110 = 70

angle bdc = 70/ 2 = 35          ( the median cuts the angle into 2)

2) cbd = x = 125

x + c + bdc = 180

In context, the word usurpations in paragraph 2 most closely meansA.wrongful possessionsB.appropriate controlsC.jaded beliefsD.pre-emptive arrestsE.rightful behaviorsHere is the paragraph:We hold these truths to be self-evident: that all men and women are created equal; that they are endowed by their Creator with certain inalienable rights; that among these are life, liberty, and the pursuit of happiness; that to secure these rights governments are instituted, deriving their just powers from the consent of the governed. Whenever any form of government becomes destructive of these ends, it is the right of those who suffer from it to refuse allegiance to it, and to insist upon the institution of a new government, laying its foundation on such principles, and organizing its powers in such form, as to them shall seem most likely to effect their safety and happiness. Prudence, indeed, will dictate that governments long established should not be changed for light and transient causes; and accordingly all experience hath shown that mankind are more disposed to suffer while evils are sufferable, than to right themselves by abolishing the forms to which they are accustomed. But when a long train of abuses and usurpations, pursuing invariably the same object, evinces a design to reduce them under absolute despotism, it is their duty to throw off such government, and to provide new guards for their future security.
