Answer:

So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth. And, the number of bull shark teeth is 4.

Step-by-step explanation:

So, the question means that if we add the number of tiger shark teeth and the sand shark teeth and subtract it from the total number of teeth, we will get the number of bull shark teeth.

Since Christian has 18 shark teeth, and 6 are tiger shark teeth, 8 are sand shark teeth and the rest are bull shark teeth.

Let x represent the number of bull shark teeth.

So, total number of shark teeth = number of tiger shark teeth + number of sand shark teeth + number of bull shark teeth.

18 = 6 + 8 + x

18 = 14 + x

subtracting 14 from both sides, we have

18 - 14 = 14 - 14 + x

4 = 0 + x

4 = x

x = 4

So, the number of bull shark teeth is 4.

Fiano borrowed $550. Four months later, he sent a cheque for $562.83 to repay the loan and interest. What was the interest rate
Digiron [165]

Answer:

Rate = 0.7%

Step-by-step explanation:

Rate = Interest / (principal x time)

rate = 12.83 / ((550) x 12/4)

rate = 12.83 / (550 x 3)

rate = 12.83 / 1650

rate = 0.007

rate = 0.7%

An equilateral triangle has a height of 10 feet. How long is one of its sides? (Note: In an equilateral triangle, all sides have
lidiya [134]

Answer:

side length is \frac{20\sqrt{3} }{3} feet

Step-by-step explanation:

An equilateral triangle has a height of 10 feet.  the height of the triangle is the perpendicular bisector to the base

so it forms a two right angle triangle

the triangle formed is a 30-60-90 degree triangle

the diagram is attached below

Let x be the side if the equilateral triangle

sin(theta)=opposite by hypotenuse

sin(60)=\frac{10}{x}

\frac{\sqrt{3}}{2} =\frac{10}{x}

cross multiply

\sqrt{3} x=20

x=\frac{20}{\sqrt{3} } =\frac{20\sqrt{3} }{3}

Help please? It would help a lot :)

a. P(2 or 4) is the probability of rolling either a 2 or a 4 on the die.
P(2 or 4) is equal to P(rolling a 2) + P(rolling a 4)
1/6 + 1/6 = 2/6 = 1/3

b. P(greater than 2) is equal to P(3) + P(4) + P(5) + P(6)
1/6 + 1/6 + 1/6 + 1/6 = 4/6 = 2/3

7. The probability of getting a head is 1/2. If you toss the coin two times, there are four different possibilities. HH, TT, HT, or TH. The answer would be 1/4, you get that by multiplying 1/2 by 1/2 again.

Y A chemist can purchase a 10% saline solution in 500 cubic centimeter containers, a 20% saline solution in 500 cubic centimeter
Nonamiya [84]

Step-by-step explanation:

ultimately you need to end up with 30% solution

with 10%, 20%, and 50%, you are forced to tamper with the various percentages to reach the desired goal.

Since it is an even 12,000 (i.e. no 12500) and you have no hard container volumes to deal with, therefore find the easiest combination to reach 30%. In this case, (10%+50%)/2 = 30%

So therefore you need 12000 cubic centimeters of liquid, half of it being 50% and half being 10%.

12000/2 = 6000 cubic centimeters each

for 50%, each container is 1,000 cubic centimeters, so 6000/1000 =6 containers  for 10% each container is 500 cubic centimeters, so 6000/500 = 12 containers

Therefore, you need 6 containers of 50% solution and 12 containers of 10% solution.

Help please loves!!!! I'm horrible at math!!!
yan [13]
There are no real solutions.

if you subtract 20 from both sides, you get
x² = -16

You cannot find the square root of a negative number without using i, so there are no real number solutions.
