If the square's diagonal is 5 and the circle is inscribed in it, that means that the radius is 2.5
2.5^2*3.14
=19.625
The graph below shows the number of pages Matthew read in x hours. Find the slope of the line. Explain what the slope represents.
Answer: The slope represents the RATE at which Matthew read pages in x hours.
Step-by-step explanation:
While I can not see the graph, I can conclude the representation from your sentence. Slope usually describes cases where an action increases or decreases over time if that makes sense. I can help you with the calculation if you add the graph! I hope this helped a bit!

Answer:
5 is the highest/greatest common factor
Step-by-step explanation:
For this, we'll factor it out:
=> 10a-25+5b
Taking 5 common
=> 5(2a-5+b)
Since All are divisible by 5, So 5 is the highest common factor.

a group of 43 children, with some adults, travelled by coach on a trip to a zoo
The total cost of the trip was £516
the entrance fee was £12.75 for each adult and£8.25 for each child
the cost of hiring the coach was £123
How many adults were in the group?
you must show your working
｡☆✼★ ━━━━━━━━━━━━━━ ☾
516 - 123 = 393
8.25 x 43 = 354.75
393 - 354.75 = 38.25
38.25 / 12.75 = 3

Answer:
3 adults
Step-by-step explanation:
(each child)£8.25×(total children)43=£354.75(total amount paid for children)
£354.75+£123=£477.75

Determine whether the forces in the pair are pulling at right angles to each other. For the values a = 1.6 and b = 5.8, which are legs of a right triangle, find c, the hypotenuse, to the nearest tenth
Answer:
Approximetly 6
Step-by-step explanation:
a^2 + b^2 = c^2
1.6^2 + 5.8^2 = c^2
2.56 + 33.64 = c^2
36.2 = c^2
c=6 (approximetly)

When dividing complex numbers, why do
you need to multiply the numerator and
denominator by the complex conjugate of the
denominator?
Answer:
Hope this helps..
Step-by-step explanation:
So when you need to divide one complex number by another, you multiply the numerator and denominator of the problem by the conjugate of the denominator. This step creates a real number in the denominator of the answer, which allows you to write the answer in the standard form of a complex number.
Answer:
You have to multiply by the complex conjugate because the denominator has to be a real number. By multiplying the complex conjugate you can transform the denominator in to a real number.

can 20 degrees 60 degrees and 100 degrees be a triangle
Answer: Yes
Step-by-step explanation: The area of a triangle equals 180°
100+60+20=180
Answer: Yes
Explanation: The sum of the measures of the angles is always 180°
This idea is known as the (Triangle Sum Theorem).
Since 20 + 60 + 100 is equal to 180, we know
that these measures can form a triangle.

Step-by-step explanation:
Quadrilateral RSTU is a parallelogram. Which is the LEAST additional information needed to prove that RSTU is a rectangle?
a
The diagonals are congruent, and one angle is a right angle.
b
c
All four angles are right angles.
d
Both pairs of opposite sides are congruent, and all angles are right angles.
Answer:
B
Step-by-step explanation:
In right triangle ABC, ∠C is a right angle, m∠A=52∘, AC=10.01, and AB=c.
sin52∘≈0.788
cos52∘≈0.616
tan52∘≈1.280
What is the measurement of AB?
In right triangle GHI, ∠H is a right angle, m∠I=42∘, and GH=11.
sin42∘≈0.67
cos42∘≈0.74
tan42∘≈0.90
What is the measurement of HI?
9514 1404 393
Answer:
AB = 16.25HI = 12.22Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relevant relationships.
__
1. Cos = Adjacent/Hypotenuse
cos(52°) = AC/AB
AB = AC/cos(52°) = 10.01/0.616
AB = 16.25
__
2. Tan = Opposite/Adjacent
tan(42°) = GH/HI = 11/HI
HI = 11/tan(42°) = 11/0.90
HI ≈ 12.22
Which of the following options best represent the equation of a function?
Select all that apply.
Options:
x + y = 16
x2 + y2 = 16
y = 2
x = 2
y = x2 + 2
y = |x + 2|
Please explain how you get your answer, ty
Answer:
y=2
x=2
y=x2+2
y= lx+2l
Step-by-step explanation:
This is because these are the simplest forms of the equation. seeing as a function is f(x) (which is the same as y) when an equation is equal to a single variable, it is "solved" for hat variable and therefore best represents the equation of the function :)

PLS I NEED HELP...THE PICTURES ARE IN ORDER (13 POINTS ) Question 1 Solve the following equation. Explain or show your reasoning. ---------------------------------------------------------------------------------------- Question 2 Solve the following equation. Explain or show your reasoning. ------------------------------------------------------------------------------------------ Clare was solving an equation, but when she checked her answer she saw her solution was incorrect. She knows she made a mistake, but she can’t find it. Where is Clare's mistake and what is the solution to the equation?
Answer:
1 . x = 9,
2 . n = 4,
3 . Clare made an error in the 2nd step; Correct answer is y = - 65 / 11
Step-by-step explanation:
1 .
[tex]2 * ( x + 5 ) = 3x + 1 - Apply Distributive Property,\\\\2x + 10 = 3x + 1 - Subtract 2x from Either Side,\\10 = x + 1 - Subtract 1 from Either Side,\\\\x = 9,\\Conclusion; x = 9[/tex]
2 .
[tex]3 * ( n + 2 ) = 9 * ( 6 - n ) - Apply Distributive Property,\\\\3n + 6 = 54 - 9n - Add ( 9n ) on Either Side,\\12n + 6 = 54 - Subtract 6 from Either Side,\\\\12n = 48 - Divide Either Side by 12,\\n = 4,\\\\Conclusion; n = 4[/tex]
3 . Clare made an error in the second step ( 72 + 24y = 4y - 5 - 9y ) and to derive the correct solution, see the following steps below;
[tex]12 * ( 5 + 2y ) = 4y - ( 5 - 9y ),\\60 + 24y = 4y - 5 + 9y,\\65 + 24y = 4y + 9y,\\65 + 24y = 13y,\\\\65 = - 11y,\\y = - 65 / 11\\\\Conclusion; y = - 65 / 11[/tex]

Answer:
50
Step-by-step explanation:
Using the experimental probability, first we have to find total amount paint then to find the amount of good quality forever paint we have to subtract the amounts of other paints from total amount.
Let x represents the amount of good quality forever paint sold.
Total amount of paint [tex]=48+45+35+39+33+x=200+x[/tex] ...(i)
Experimental probability of paint sold will be better quality durable paint is
[tex]P=\dfrac{\text{Amount of better quality durable paint}}{\text{Amount of total paint}}[/tex]
[tex]P=\dfrac{45}{\text{Amount of total paint}}[/tex]
It is given that experimental probability of paint sold will be better quality durable paint is [tex]\frac{9}{50}.[/tex]
[tex]\frac{9}{50}=\dfrac{45}{\text{Amount of total paint}}[/tex]
[tex]\text{Amount of total paint}=\dfrac{45\times 50}{9}[/tex]
[tex]\text{Amount of total paint}=250[/tex] ...(ii)
From (i) and (ii), we get
[tex]200+x=250[/tex]
[tex]x=250-200[/tex]
[tex]x=50[/tex]
Therefore, 50 gallons good quality forever paint is sold.

six copies of the sum of nine fifths and three.
Answer:
9/5+3/1
24/5 24/5 24/5 24/5 24/5 24/5
i think copies is a multiplication and sum is to add together so
6x(9/5+3)
9/5 is 1 whole and 4/5. 1 whole plus 3 wholes is 4 Wholes so it is 4 wholes and 4/5 which is 24/5.
6x24/5 is (6x24 is 144) so its 144/5 so its 28 wholes and 4/5.
Solve for x in the triangle. Round your answer to the nearest tenth.
Answer:
x = 6.9
Step-by-step explanation:
We're going to use SOH CAH TOA.
If we look at the angle (58°), and see what the relevant sides of the triangle are, we can see that the hypotenuse (our known side) is the H (hypotenuse), and the side labelled 'x' (our unknown side) is the A (adjacent).
According to SOH CAH TOA, we'll use cos (C), since we're working with the adjacent and the hypotenuse.
The equation for CAH is cos (Ф°) = A/H
In this case, Ф = 58°, A = x, and H = 13
So cos (58°) = x/13
Solve for x by multiplying both sides by 13 and using your calculator to evaluate.
13 cos (58°) = x
x = 6.88895
To the nearest tenth, x = 6.9
