ABCD is an isosceles trapezoid with legs AB and CD and with base BC. If AB=6z - 5 and BC = 7z +4 and CD = 4z +3
Answer:
Step-by-step explanation:
As it is an isosceles trapezoid,
AB = CD
6z - 5 = 4z + 3
To find the value of z, isolate z.
Add 5 to both sides
6z = 4z + 3 + 5
6z = 4z + 8
Subtract 4z from both sides
6z - 4z = 8
2z = 8
Divide both sides by 2
z = 8/2
z = 4
AB = 6z - 5
= 6*4 - 5
=24 - 5
AB = 19
CD = 4z + 3
= 4*4 +3
= 16 +3
CD = 19
BC = 7z + 4
= 7*4 + 4
= 28 + 4
BC = 32
Simplify the expression
Answer:
Step-by-step explanation:
7x³ - x²/ 2x³
= x²(7x - 1)/ 2x³
= x × x(7x - 1)/ 2 × x × x × x
= 7x - 1/2x

A pizza parlor cuts their pizzas into six pieces
a) what fraction of the pizza is each slice?
b)Joan ate 1 3/4 or 7/4 pizzas. How many slices was that knowing that they cut each pizza in 6 pieces?
c) How many slices are left over? Pls explain! :)
I will give you 50 POINTS:D
Answer:
Hi im not sure but if I was doing this this is what i would say
Step-by-step explanation:
a) since the pizza is split in 6th then the pizza would be 6/6th
b) 7/4 is equal to 1 2/4 ( not 100% simplified ) but 1 2/4 also equals to 6/6ths because 1 2/4 = 4+2=6 (not the best accurate explanation )
c) no slices are left over if joan ate 7/4th of the pizza XD

Find the equation of a line that passes through the point (3,4) and has a gradient of 4.
Leave your answer in the form y= mx + c
HELP ASAP WIL LGIEV BRANLIEST FOR CORRECT ANSWER
Answer:
y=4x-8
Step-by-step explanation:
Y=mx+c
4=4(3)+c
C=-8
y=4x-8
Step-by-step explanation:
given that gradient i.e. m= dy/dx = 4.
equation passes through point (3,4)...
(Y - y1) = m (X-x1)
Y-4 = 4(X-3)
Y-4 = 4X-12
or Y = 4X-8

The initial investment is compounded annually 3.25%
That means the equation will look like this:
[tex]500(1 + 0.0325) = 500 + 500 * 0.0325[/tex]
500(1 + 0.0325) is the initial investment plus the initial investment times the percentage which in the end will give you the total amount after the investment is compoundedHowever, we want it compounded yearly for every year after the first initial investment
---> [tex]500(1+0.0325)^t[/tex]
Therefore the equation is the amount of money in the account after 't' year or the second choice.
Hope it helps!
p.s. the diagram I attached will help you understand where I got my equations from
Compare to the compound interest formula
[tex]\\ \rm\longmapsto P(1+r)^nt[/tex]
nt is number of yearsnow
P(t)=500(1+0.0325)^tt years is correct

The terminal ray of ∠A passes through the point (−4,−6). ∠A is drawn in standard position. What is the value of cscA?
The terminal ray of an angle A passes through the origin
The value of csc(A) is -1.2
How to determine the cosine of angle AThe coordinates of the terminal ray is given as:
(x,y) = (-4,-6)
Start by calculating the length (L) of the hypotenuse
[tex]L = \sqrt{x^2 + y^2}[/tex]
So, we have:
[tex]L = \sqrt{(-4)^2 + (-6)^2}[/tex]
Evaluate the exponent
[tex]L = \sqrt{52}[/tex]
Evaluate the root
[tex]L = 7.2[/tex]
The sine of the angle A is then calculated as:
[tex]\sin(A) = \frac{-6}{7.2}[/tex]
The csc of the angle A is then calculated as:
[tex]\csc(A) = \frac{1}{\sin(A)}[/tex]
So, we have:
[tex]\csc(A) = \frac{7.2}{-6}[/tex]
[tex]\csc(A) = -1.2[/tex]
Hence, the value of csc(A) is -1.2

5(8 + 7) = 5•x + 5•7
Answer:
x = 8
Step-by-step explanation:
5( 8 + 7 ) = 5 ⋅ x + 5 ⋅ 7
Add 8 and 7 to get 15.
5 × 15 = 5x + 5 × 7
Multiply 5 and 15 to get 75.
75 = 5x + 5 × 7
Multiply 5 and 7 to get 35.
75 = 5x + 35
Swap sides so that all variable terms are on the left-hand side.
5x + 35 = 75
Subtract 35 from both sides.
5x = 75 − 35
Subtract 35 from 75 to get 40.
5x = 40
Divide both sides by 5.
x = [tex]\frac{40}{5}[/tex]
Divide 40 by 5 to get 8.
x = 8
