A herd of dinosaurs made paintings in the sand with their claws.
Each baby dinosaur made 15 paintings and each adult dinosaur made 7 paintings. The entire herd made 208 paintings in total, and there were 3 times as many baby dinosaurs as adult dinosaurs.
How many baby dinosaurs and adult dinosaurs were there?
There were ____ baby dinosaurs and ____ adult dinosaurs.
Answer:
Baby dinosaurs-12
Adult dinosaurs-4
Explanation:
15b+7a=208 where b- baby , a is adult
b=3a
Putting the values
15.3a+7.a= 208
45a+7a =208
52a=208
a=4
b=3a= 12

The average surface temperature of a red giant star is much cooler than that of a white dwarf star. Suppose a white dwarf has a surface temperature of 1.2 x 10*4 Kelvin (abbreviated K), which is 4 times the temperature of a red giant star. WHat is the surface temperature of the red giant star?
Answer: 3000 Kelvin
Step-by-step explanation
Let the surface temperature of the red giant star = x
Surface temperature of a white dwarf star = 4x
4x = 1.2 × 10^4 K
= 1.2 × 10,000 K
= 12,000 K
4x = 12,000 K
x = 12000 ÷ 4
= 3,000 K

Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.
The correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.
How to convert from decimal to fraction?For conversion from decimal to fraction, we write it in the form a/b such that the result of the fraction comes as the given decimal. Usually, to get the decimal of the form a.bcd, we count how many digits are there after the decimal point (if its finite), then we write 10 raised to that many power as denominator, and the considered number without any decimal point as numerator.
For example:
[tex]0.99 = \dfrac{99}{10^2} = \dfrac{99}{100}[/tex]
(10 raised to power k = 1 followed by k zeroes)
How to add two fractions?Let we have to add two fractions as:
[tex]\dfrac{a_1}{b_1} + \dfrac{a_2}{b_2}[/tex]
Then we will find Lowest Common Multiple (LCM) of [tex]b_1[/tex] and [tex]b_2[/tex]. That will help to make the denominators same.
Once the denominators become same, the numerators can add up directly, giving us the final result of addition.
For this case, we can see from the image that:
Weight shown = 3 pounds + half more pound + half of 1/10 pound more approx. (as the weight hand is approx between 5 and 6 minor ticks after the big 3 pound mark). In each minor mark, one pound is divided in 10 parts, so each minor tick adds up 1/10 of a pound. Half of 1/10 shows that after 5, the hand is not exactly on 6 but sort of in between them, so approximately half.
Thus, weight shown ≈ 3 + 0.5 (half is written 0.5 too) + 1/10 of 0.5 pounds
= 3 + 0.5 + 0.5/10 = 3.5 + 0.05 = 3.55 pounds
Thus, the weight is approx 3.55 pounds.
Converting it to fraction, we get:
[tex]3.55 = \dfrac{355}{100} = \dfrac{5 \times 71}{5 \times 20} = \dfrac{71}{20}[/tex] pounds.
Thus, the correct weight to the nearest 1/8 pound from the considered image is 3.55 pounds. In reduced fraction form, it is 71/20 pounds approx.

Pharmacy a lot!!!!
John arrived at work early in the morning at the home infusion pharmacy and discovered there was an order for furosemide 40 mg to be administered by IV infusion that needed to be sent out right away. He decided to mix the compound right away so it would be ready for the pharmacist to check when she arrived. He flipped a switch to turn the laminar flow workbench on and gather the needed materials. He put on a gown, washed his hands thoroughly, and place the supplies carefully in the hood. Because the furosemide was packaged in ampul, john remember to obtain a filter needle to remove any glass particle that might result from breaking the ampul. He attach the filter needle to the syringe and snap the tip of the ampul by holding it with his thumbs and index fingers and applying pressure with his thumbs. The glass scraped his finger as the lid came off, but there wasn’t much bleeding, so he continued. Using the filter needle and syringe, John withdrew the furosemide from the vile and carefully injected it into the injection ports of the piggyback bag. He remove the bag from the hood and placed it in the checking area, where he attached the appropriate labels. As he finished, the pharmacist arrived and came over to check the medication. John felt proud that he was able to complete the admixture in a timely manner so it could be sent out to the patient. The pharmacist checked the bank, initialed the paperwork, and sent back out for delivery.
Did john follow all the 797 guidelines for compounding a sterile product??
Answer:
not really, if at one point he was bleeding a little, he still should have done something about it instead of continuing and risking contaminating whatever it was

Please give me a good answer, I don't got time for point takers..
Answer:
54j + 72 + 9j and 63j + 72
Step-by-step explanation:
I just simplified it
So 9(6j + 8 + 1j) can be distributed to (9)(6j) + (9)(8) + (9)(1j) which equals 54j + 72 + 9j because 9*6j = 54 , 9*8 = 72 , and 9*1j = 9j
54j + 72 + 9j can also equal 63j + 72 because 54j + 9j = 63j

Measurements of atoms, such as amounts, distances, and weights, are often very large or very small when compared to measurements of things you can see or touch. Scientific notation represents numbers as a power of 10. This makes very large or small numbers easier to use and understand. Approximately 7,500,000,000,000 carbon atoms fit across the period that you make with your pencil. Express this number in scientific notation. (PLEASE ANSWER FAST I'LL GIVE BRAINLIEST ALSO PLEASE DO ALL THIS IS WORTH 30 POINTS)
Step 1 Rewrite the number with a decimal after the first nonzero digit.7.500000000000
Step 2 Find the number of places and the direction you moved the decimal. If a number does not show a decimal, the decimal is at the right end of the number.You moved the decimal 12 places to the left.
Step 3 Drop the zeros, and write the number of places you moved the decimal as a power of 10. If you moved the decimal to the right, the power is negative. If you moved the decimal to the left, the power is positive.7.5 × 10 12
Step 4 Reverse the process to change scientific notation back to a whole number. A positive power of 10 moves the decimal to the right. A negative power of 10 moves the decimal to the left.
