A square is put together by two triangles. The hypotenuse is 11 cm and width of 8 cm. find the height of triangle?

Aleks [24]

You can use the pythagorean theorem. Make sure that you put the measurements in the right places though. Since 11 is the measure of the hypotenuse, 11 has to be c. When you plug in the information that you have, it should look like this:
8^2 + b^2 = 11^2

Square 8 and 11.
64 + b^2 = 121

Subtract 64 from 121
121 - 64 = 57

The new equation is:
b^2 = 57

Now take the square root of both sides to get b by itself.
b = about 7.5

Answer: The height of the triangle is 7.5

X + 3x² – 28x <br><br> Can you guys help me solve this in ax^2+bx+c <br> Thank you thank you

Molodets [167]

Answer:

3x²+(-27x) +0

Step-by-step explanation:

The given expression is :

x + 3x² – 28x

We need to solve this in the form of ax²+bx+c.

we can write the given expression as :

3x²-28x+x = 3x²-27x

= 3x²+(-27x) +0

If we compare the given expression with the general expression, we find that,

a = 3, b = -27 and c = 0

Hence, the required equation is 3x²+(-27x) +0.

An effervescent tablet has the following formula: acetaminophen 325 mg, calcium carbonate 280 mg, citric acid 900 mg, potassium

Oksana_A [137]

Answer: a) 2.27 g and b) 15384

Step-by-step explanation:

Given : An effervescent tablet has the following formula:

acetaminophen 325 mg,

calcium carbonate 280 mg,

citric acid 900 mg,

potassium bicarbonate 300 mg, and

sodium bicarbonate 465 mg.

a) When we add all quantities together , we get

The total weight of the ingredients in each tablet = $325 +280+900+300+465=2270$

Since, 1 gram = 1000 mg

Then, $1\ mg=\dfrac{1}{1000}\ g$

Now, $2270\ mg=\dfrac{2270}{1000}\ g=2.27\ g$

∴ The total weight of the ingredients in each tablet = 2.27 g

b. 1 kg = 1000g and 1 g = 1000 mg

Then, 1 kg = $1000\times1000=1000,000\ mg$

⇒ 5 kg = 5000,000 mg

Now, The number of tablets could be made with a supply of 5 kg of acetaminophen will be :

$\dfrac{5000000}{325}=15384.6153846\approx15384$

Hence, the number of tablets could be made with a supply of 5 kg of acetaminophen= 15384
