The answer: X = 3 and Y =-1
Answer:
(a) see attached
(b) CD = 29
Step-by-step explanation:
<h3>(a) </h3>
See the attachment for a diagram.
In the diagram, we have shown point E on the plane so that BE is parallel to AC.

<h3>(b)</h3>
Triangle BDE is a right triangle with hypotenuse BD = 25 and leg BE = AC = 15. The length DE is given by the Pythagorean theorem as ...
DE = √(BD^2 -BE^2) = √(625 -225) = 20
Triangle CDE is a right triangle with hypotenuse CD and legs CE = 21 and DE = 20. The length of the hypotenuse is also given by the Pythagorean theorem as ...
CD = √(CE^2 +DE^2) = √(21^2 +20^2) = √841
CD = 29
I think no, because a pyramid's lateral face is a triangle, and he can only draw a prism if it's rectangular
Answer:
Step-by-step explanation:
In this question we have to find the expression for the value of temperature in terms of degrees Celsius.
Since, the given expression is,
F = 1.8C + 32
F - 32 = 1.8C + 32 - 32
F - 32 = 1.8C


For F = C,

C - 32 = 1.8C
C - 1.8C = 32
-0.8C = 32
C = 
C = -40
Therefore, at (-40°C) degrees of temperature degrees Fahrenheit and degrees Celsius are equal.
Answer:
1.5 ml
Step-by-step explanation:
We have been given that the concentration on hand is 10 mg per ml.
We know that gr stands for grains.
We know that 1 gr equals 60 mg.
First of all, we will convert 1/4 gr to mg as:



1 ml equals 10 mg. We can set an a proportion as:




Therefore, 1.5 ml is needed for the dose.
