please help me , step by step explanation needed
=======================================================
Explanation
Part (a)
The smaller pyramid up top is the result of slicing at the halfway point.
This leads to the ratio 1:2 when comparing small side to larger side.
Cube both parts of that ratio to end up with 1:8 as the volume ratio.
This means if the smaller pyramid was say 1 cubic foot in volume, then the larger pyramid has a volume of 8 cubic feet.
-------------------------
Part (b)
Consider the case that,
volume of smaller pyramid = 1 cubic feetvolume of larger pyramid = 8 cubic feetThe volume of the truncated base is 8-1 = 7 cubic feet.
The ratio of the smaller pyramid to the truncated base is 1:7
Write an equation for the sentence below.
The sum of three times a number (x) and -23−23 is 2828.
Answer:
3x - 23 = 2828
Step-by-step explanation:
I'll assume the question is supposed to read "The sum of three times a number (x) and −23 is 2828."
"three times a number (x)" can be written as 3x
"sum of three times a number (x) and −23" means 3x - 23
"is 2828" = 2828
Put them together:
3x - 23 = 2828
==================
Not part of the question
If you want to solve for x:
3x = 2805
x = 935
Rationalize the denominator!
Question in the picture
Answer:
A
Step-by-step explanation:
[tex]\frac{10}{9+\sqrt{7} }[/tex]
To rationalise the denominator multiply the numerator and denominator by the conjugate of the denominator.
the conjugate of 9 + [tex]\sqrt{7}[/tex] is 9 - [tex]\sqrt{7}[/tex]
= [tex]\frac{10(9-\sqrt{7}) }{(9+\sqrt{7})(9-\sqrt{7}) }[/tex] ← expand denominator using FOIL
= [tex]\frac{90-10\sqrt{7} }{81-7}[/tex]
= [tex]\frac{90-10\sqrt{7} }{74}[/tex] ( divide terms on numerator/ denominator by 2 )
= [tex]\frac{45-5\sqrt{7} }{37}[/tex] → A
Answer:
A[tex]\frac{45-5\sqrt7}{37}[/tex]
Step-by-step explanation:
Easy. First let's multiply numerator and denominator by [tex]9-\sqrt7[/tex] since we will create a difference of squares to get rid of the root, then start doing the calculations
[tex]\frac{10(9-\sqrt7)}{(9+sqrt7)(9-\sqrt7)}=\frac{10(9-\sqrt7)}{81-7} = \frac{10(9-\sqrt7)}{74} =\\\frac{5(9-\sqrt7)}{37}=\frac{45-5\sqrt7}{37}[/tex]

$4750 invested at 10% p.a compounded semiannually for 10 years, calculate the interest
Work Shown:
A = P*(1+r/n)^(n*t)
A = 4750*(1+0.10/2)^(2*10)
A = 12,603.164099436
A = 12,603.16
That represents the account balance after 10 years. To find the interest only, subtract off the deposit amount.
interest = A-P = 12,603.16 - 4,750 = 7,853.16

You have learned what tangent lines are. You have learned that they are perpendicular to the radius at a point on the circle. What is unique about a tangent line is that it touches the circle at exactly one point, but never goes inside the circle. But points are infinitely small … how can a line touch a circle without ever going into it?
Answer:
In Euclidean plane geometry, a tangent line to a circle is a line that touches the circle at exactly one point, never entering the circle's interior. Tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs.

if there are 280 6th graders and 200 7th graders then how many more seventh graders are involved in the yearbook
Using proportions, it is found that 8 more seventh graders are involved in the yearbook.
What is a proportion?A proportion is a fraction of a total amount.
Researching the problem on the internet, it is found that 10% of the 6th graders and 18% of the 7th graders are on the yearbook, hence:
0.1 x 280 = 28 6th graders.
0.18 x 200 = 36 7th graders.
36 - 28 = 8
8 more seventh graders are involved in the yearbook.

Answer:

Step-by-step explanation:
Important info given:
two triangles. A triangle has a base A and height 8 cm.Another triangle has a base of 3 cm and height of 4 cm.Step 1: We need to determine the length of side A.
Since, these two triangles are similar, let us use the property of similarity of triangles to determine the length of side A.
Therefore we have:
[tex]\frac{8}{4} = \frac{a}{3}[/tex]
Step 2: Multiplying by 3, and then we have:
[tex]\frac{8*3}{4}=a[/tex]
[tex]\frac{24}{4}=a[/tex]
Step 3: Simplify, and we get:
6 = a
Hence, the length of side A is 6 cm.
