The front pentagon face, the upper right rectangle face, and the lower right rectangular face. The face in the front has 5 sides that are all equal. Starting from the top point and going clockwise, the vertices of the pentagon are A, H, E, F, G. A line is drawn and extended out at side H E , side F E, ,and side F G of the pentagon. The top right face of the prism is a rectangle and it touches side A H of the pentagon. This rectangle has vertices A, B, C, H in clockwise order. A line is drawn at side A B and side H C. The face on the right side of the prism is a rectangle that shares side H E with the pentagon. The rectangles has vertices H, C, D, E in clockwise order. A line is drawn at side H E and C D.

Opposite sides of any rectangular face are parallel, because opposite sides of a rectangle are parallel.

Since HCDE is a rectangle, CD ║ HE.

Since ABCH is a rectangle, AB ║ HC.

Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner.explain
GarryVolchara [31]
Okay, so:

You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.

So,

423*.1

(you have to turn the percentage into a decimal; 10%= .10


423*.1= 42.3

So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.

I hope this helps!

Mrs. R is pregnant and very worried that the child will have beta-thalassemia. What is the probability that the child will have
kenny6666 [7]

Answer:

There are three kind of beta-thalassemia.

Total possible outcome=  3 types of beta- thalassemia + 1 [child will have no trace of disease] = 4

As we know Probability(outcome) = \frac{\text{ Total favorable outcome}}\text{Total possible outcome}

Probability that the child will have beta-thalassemia major =\frac{_{1}^{3}\textrm{C}}{_{1}^{4}\textrm{C}}

     =\frac{3}{4}

   ∴ favorable=_{1}^{3}\textrm{C}

 And , Total =_{1}^{4}\textrm{C}

Probability that the child will have no trace of the disease=\frac{1}{4}

Wittaler [7]

Answer:

7

Step-by-step explanation:

I don't completely understand what you were asking, but if you were counting by 7's, 91 would be after 84 instead of just 90.
