A microscope slide shows 37 red blood cells out of 60 blood cells . How many red blood cells would be expected in a sample of th
JulsSmile [24]

We know that there is a total of 900 cells, and 37 of the samples 60 are red. 900/60 is our unit rate of 15. 37 times 15 is 555. We will see 555 red blood cells in all of the cells.

555 is our answer.

Please forgive any typeos because I did this on my phone.

Carlos found the area of the figure check his work and explain any errors​
Zanzabum

Answer:

The correct are is 5.5 cm².

Step-by-step explanation:

First of all, Carlos calciulated the are of the rectangle correctly, only the are unit is wrong, it should be 3 cm².

He made a mistake calculating the area of a the triangle: The area of a triangle can be calculated by multiplying the base by the height by \frac{1}{2}.

(Comment if you want a deeper explanation on where this comes from)

He mistakenly takes 4 cm for the height, but if you look carefully the height of the triangle in this case is 4 cm - 1.5 cm = 2.5 cm.

That gives \frac{1}{2} * 2 cm  * 2.5 cm = 2.5 cm^2 for the area of the triangle.

Adding those two together gets you a total area of 5.5 cm².

The second angle of a triangle is double the first angle. The third angle is 40 less than the first angle. Find the three angles
ArbitrLikvidat [17]

Answer:

Angle 1: 55

Angle 2: 110

Angle 3: 15

Step-by-step explanation:

Angle 1: x

Angle 2: 2x

Angle 3: x-40

The total degrees for all the angles in a triangle add up to 180, so we now have the equation x+2x+x-40=180. From here we solve to get 55 degrees for x, so angle 1 is 40 degrees, angle 2 is 110 (2 times 40) and the third angle is 15 (55-40).

Set up and solve a system of equations to solve the problem.
olga2289 [7]

Answer:

Hardwood = 56 bags,

Bag and Pine = 100 bags

Step-by-step explanation:

let number of bags of hardwood be x and for pine be y

4.25x+3.75y=613----equation1

x+y=156 ---equation2

rewrite equation2 as y=156-x

substitute to equation1 = 4.25x+3.75(156-x)=613

simplify to get x = 56

from equation 2, y=156-x

y=156-56 = 100

Therefore

Hardwood = 56 bags,

Bag and Pine = 100 bags
