Esi says that the value of z when z^2 = 80 does not belong in either of these categories since z must be greater than 8.
What whole number would z be closest to?
(please explain)
Answers
Answer:
9
Step-by-step explanation:
if z=8 then z^2 would be 64, which is not equal to 80
iz z=9 then z^2 would be 81, which is closer to 80 than 64
therefore, 9 is the whole number than z would be closest to

Jasper had a sports card album that held 100 cards. He filled 42/100 with football cards and 3/10 with baseball cards. What fraction of the album is still empty?
A. 28/100
B. 45/100
C. 55/100
D. 72/100
Answers
The fraction of the album that is still empty is 28/100, the correct option is A.
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given that;
The fraction 42/100
Now,
To rewrite 3/10 with a denominator of 100, we need to multiply both the numerator and denominator by 10. This gives us:
3/10 = (3 × 10) / (10 × 10) = 30/100
Now, we can add the numerators of the fractions and write the sum over the common denominator.
42/100 + 30/100 = (42 + 30) / 100 = 72/100
Therefore, the total fraction of the album that is filled with football and baseball cards is 72/100.
we need to subtract the fraction that is filled from the whole fraction, which is 1 or 100/100. To subtract fractions, we need to have a common denominator, which we already have as 100. So, we can subtract the numerators of the fractions and write the difference over the common denominator.
100/100 - 72/100 = (100 - 72) / 100 = 28/100
Therefore, the fraction will be 28/100.

The length of the line segment QU diagram containing three right triangles is 3 centimeters.
How find a missing length in a triangle system by similarity propertiesIn the figure given below we have a system of three distinct right triangles connected by three colinear segments. Given that the three triangles are similar, we can make of geometry properties for similarity to determine the length of the missing line segment.
In this question we must find a missing length by similarity properties, which is represented mathematically by proportions. From the figure we have the following relationship:
5/y = (5 - x)/(5 - y) = x/1 (1)
From (1) we have the following two formulas:
x = 5/y (2)
x = (5 - x)/(5-y) (3)

A triangle has perimeter 3a+11. One side is 2a and another side is 8. What is the third side?
Answers
Answer:
1a + 3
Step-by-step explanation:
What's the perimeter of a triangle?
❖ The perimeter of a triangle is the distance around a triangle, or the
sum of all its side lengths.
How does it apply here?
❖ In this case, we're given the perimeter of the triangle as 3a + 11. We
also have two dimensions of the triangle: 2a and 8. Now, we need to
find the third side. To find the third side, we subtract 2a + 8 from 3a +
11.
Solving
[tex](3a+11)-(2a+8)[/tex] [tex]3a+11-2a-8[/tex] [tex]1a+3[/tex]Now, let's check if 1a + 3, 2a, and 8 add up to 3a + 11.
[tex]1a + 3 + 2a + 8[/tex] [tex](1a+2a)+(3+8)[/tex] [tex]3a+11[/tex]Therefore, the answer is 1a + 3.

calculators, computer software, or tablet applications) in order to solve them. You are
encouraged to use technology to explore, and to formulate and test conjectures. Keep the
following guidelines in mind: write before you calculate, so that you will have a clear record
of what you have done; be wary of rounding mid-calculation; pay attention to the degree of
accuracy requested; and be prepared to explain your method to your classmates. If don’t
know how to perform a needed action, there are many resources available online. Also, if
you are asked to “graph y = (2x−3)/(x+1)”, for instance, the expectation is that, although
you might use a graphing tool to generate a picture of the curve, you should sketch that
picture in your notebook or on the board, with correctly scaled axes.

Joey dirves his car 80 miles per hour on the highway. Write an equation that ralates his distance traveled (d) to the time elapsed (t)
Use your equation to determine how many hours it will take joey to travel 320 miles
Answers
Answer:
d=80+t
Step-by-step explanation:
An equation that relates his distance travelled (d) to the time elapsed (t) is d = 80t and the time taken to travel 320 miles is 4 hours.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given that,
Joey drives his car 80 miles per hour on the highway.
For 1 hours, the distance travelled is 80 miles,
For t hours, the distance travelled will be 80t miles.
So, distance, d = 80t, which is the required equation.
When the distance is 320 miles, the time taken to travel it is,
t = d / 80
t = 320 / 80
t = 4 hours
Hence the time taken to travel 320 miles is 4 hours.

How can I factor 5x^2 + 26x - 24 = 0 using the completing the square method.
Answers
— — — — — — — — — —
Step-by-step explanation:How can we factor 5x^2 + 26x - 24 = 0 using the completing the square method?
Let's solve your equation step-by-step.
[tex] \bold{Given \: Equation: \color{brown} 5x²+26x-24=0}[/tex]
First, add 24 to both sides.
[tex] \bold{5x²+26x-24 - \purple{ 24} = 0 + \purple{24}}[/tex][tex] \bold{ \implies \: 5x²+26x = 24 }[/tex]Since the coefficient of 5x² is 5, divide both sides by 5.
[tex] \bold{ \frac{5 {x}^{2} + 26x }{5} = \frac{24}{5} } \\ [/tex][tex] \bold{ \implies \: {x}^{2} + \frac{26}{5} x = \frac{24}{5} } \\ [/tex]The coefficient of 26/5x is 26/5. So, let b=26/5.
Then we need to add (b/2)²=169/25 to both sides to complete the square.
Add 169/25 to both sides.
[tex] \bold{ {x}^{2} + \frac{26}{5} x + \frac{ \purple{169}}{ \purple{25}}= \frac{24}{5} + \frac{ \purple{169}}{ \purple{25}} } \\ [/tex][tex] \bold{ \implies \:\bold{ {x}^{2} + \frac{26}{5} x + \frac{ 169}{ {25}}= \frac{289}{25} } } \\ [/tex]Factor the left side.
[tex] \bold{(x + \frac{13}{5} ) {}^{2} = \frac{289}{25} } \\ [/tex]
Take square root.
[tex] \bold{x + \frac{13}{5} = ± \: \sqrt{ \frac{289}{25} }} \\ [/tex]Then, add (-13)/5 to both sides.
[tex] \bold{x + \frac{13}{5} + \frac{\purple{ - 13} }{\purple{ 5}} = \frac{{ - 13} }{{ 5}} ± \: \sqrt{ \frac{289}{25}}} \\ [/tex][tex] \bold{ \: x = \frac{ - 13}{5} ± \sqrt{ \frac{289}{25} } } \\ [/tex][tex] \implies \: \underline{ \boxed{ \bold{ \frac{4}{5} } \sf \: \: or \: \: \bold{ x = - 6}}} \\ [/tex]_______________❖_______________

Two angles are complementary. One angle is equal to x + 6 degrees. The other is 3x +9 degrees. What is the measure of x?
Answers
Answer:153
Step-by-step explanation:3x9=27 so then you do 180-27=153 then 153 is your answer i'm sorry if this is incorrect
Hey there!
=> x + 6 + 3x +9 = 90°
=> 4x + 9 + 6 = 90°
=> 4x + 15 = 90°
=> 4x = 90° - 15
=> 4x = 75
=> [tex] \frac{4x}{4} = \frac{75}{4} [/tex]
=> [tex]x = \frac{75}{4} [/tex]
=> x = 18.75
Then ,
=> 18.75 + 6, 3(18.75) + 9
=> 24.75, 65.25
Therefore, the two angles are 24.75 and 65.25
