Answer:
Hello! answer: 45
Step-by-step explanation:
90 + 45 + 45 = 180 therefore z = 45 hope that helps!
The figure below that can be used to prove that Stephen is wrong is Isosceles Trapezoid. Option C is correct. This is further explained below.
<h3>What is
Isosceles Trapezoid?</h3>
Generally, Isosceles Trapezoid is simply defined as a trapezoid with base angles that are the same and non-parallel sides that are the same is called an isosceles trapezoid. If a quadrilateral has just one parallel side, we call it a trapezoid.
In conclusion, If you want to show Stephen he's incorrect, you may use the Isosceles Trapezoid in the diagram below as evidence.

Answer:
38.4
Step-by-step explanation:
it took 48 minutes and the app miss estimated by 9.6, which is 20% of 48. So subtract 9.6 from 48 and you will get 38.4

Answer:
y = 3.02x^3 -5.36x^2 +5.68x +8.66
Step-by-step explanation:
Your graphing calculator (or other regression tool) can solve this about as quickly as you can enter the numbers. If you have a number of regression formulas to work out, it is a good idea to become familiar with at least one tool for doing so.

If you're trying to do this by hand, the x- and y-values give you 4 equations in the 4 unknown coefficients.
a·1^3 +b·1^2 +c·1 +d = 12
a·3^3 +b·3^2 +c·3 +d = 59
a·6^3 +b·6^2 +c·6 +d = 502
a·8^3 +b·8^2 +c·8 +d = 1257
Solving this by elimination, substitution, or matrix methods is tedious, but not impossible. Calculators and web sites can help. The solutions are a = 317/105, b = -75/14, c = 1193/210, d = 303/35. Approximations to these values are shown above.
Answer: 8/9 cups
Step-by-step explanation:
The word 'of' means 'times' as far as fractions are concerned. In this case, we have 1/3 of 2 1/3.
First, it is a good idea to make 2 1/3 an improper fraction - as 8/3, so now we have:
1/3 of 8/3, but since 'of' means 'times' we have,
1/3 x 8/3 = 8/9
The answer is 8/9 cups.
