This week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday. If Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days?
Answer:
Jose will have played the guitar for 9.1 hours during those 6 days.
Step-by-step explanation:
Given that this week Jose played guitar for 3/4 of an hour on Tuesday, an hour and a half on Thursday, and 2.3 hours on Saturday, to determine, if Jose plays guitar for the same amount of time next week, how many hours will he have practiced over these 6 days, the following calculation must be performed:
3/4 = 0.75
1/2 = 0.5
(0.75 + 1.5 + 2.3) x 2 = X
4.55 x 2 = X
9.10 = X
Therefore, Jose will have played the guitar for 9.1 hours during those 6 days.

A, B and C are the points (3, 4, (7,3) and (-2, 1) respectively. Obtain the
equation of the median through B of triangle ABC.
Answer:
[tex]y=\frac{1}{13} x+\frac{32}{13}.[/tex]
Step-by-step explanation:
1. the midpoint of the side AC is:
[tex]D:(\frac{3-2}{2};\frac{4+1}{2})=(0.5;2.5).[/tex]
2. if the coordinates of the points B and D are (7;3) and (0.5;2.5) respectively, then it is possible to make up the required equation of the median BD:
[tex]\frac{x-7}{7-0.5}=\frac{y-3}{3-2.5}; \ \frac{x-7}{13}=\frac{y-3}{1}[/tex]
or
[tex]y=\frac{1}{13} x+\frac{32}{13}[/tex]

A car wash had to make sure their soap lasted 2 days. If they only have one sixth of a gallon of soap, how much should they use each day so it lasts 2 days?
Answer:
1/12th
Step-by-step explanation:
so if you dived 1/6 by 2 you get 1/12 so if you use 1/12 for 2 days then you use 1/6 gallons of soap.

Suppose a group of research proposals was evaluated by a panel of experts to decide whether or not they were worthy of funding. When these same proposals were submitted to a second independent panel of experts, the decision to fund was reversed in 52 % of the cases. If the probability that a proposal is judged worthy of funding by the first panel is 0.27, what is the probability that a worthy proposal is disapproved by both panels
Answer:
0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels
Step-by-step explanation:
We have that:
0.27 = 27% of the time, the proposal is judged worthy of funding by the first panel. So 100 - 27 = 73% probability of being disapproved.
52% of the time, the independent panel reverses the decision. So if the first panel disapproves the funding, 52% probability the second approves the funding and 100 - 52 = 48% probability it does not.
What is the probability that a worthy proposal is disapproved by both panels?
48% of 73%. So
0.48*0.73 = 0.3504
0.3504 = 35.04% probability that a worthy proposal is disapproved by both panels

Leslie tunes musical instruments. Leslie tuned a guitar with 6 strings today. Then she tuned a piano with 37 times as many strings.
How many strings did the piano have?
Choose 1 answer:
(Choice A)
The piano has 422 strings, because 37×6=422.
(Choice B)
The piano has 222 strings, because 37×6=222.
(Choice C)
The piano has 6 strings, because 37÷6=6 remainder 1.
Answer: The piano has 222 strings, because 37×6=222.
Step-by-step explanation:
Since we are informed that Leslie tuned a guitar with 6 strings today and that she then tuned a piano with 37 times as many strings.
This simply means that we have to multiply 37 by 6 strings to get the value of the strings of the piano that she tuned. This will be:
= 6 × 37
= 222 strings.
Leslie tuned 222 strings.
Therefore, the piano has 222 strings, because 37×6=222.

Answer:
A, D
Step-by-step explanation:
The figure looks symmetrical, but their is no given information indicating it actually is symmetrical. Thus we can't make any statements about the segment lengths. Nor is there any indication that any of the arc lengths are identical.
If we rule out statements about segments and arcs, that only leaves statements about angles. As it happens both of those are true: inscribed angles that intercept the same arc are congruent.
The true statements are ...
A: ∠CAD≅∠CBD
D: ∠ACB≅∠ADB
AB= Round your answer to the nearest hundredth. 3 3 65 B
Answer:
AB = 7.10
Step-by-step explanation:
Reference angle = 65°
Hypotenuse = AB = ?
Adjacent side length = BC = 3
Apply the trigonometric ratio CAH, to find AB.
Cos 65 = Adj/Hyp
Cos 65 = 3/AB
AB*Cos 65 = 3
AB = 3/Cos 65
AB = 7.09860475
AB = 7.10 (nearest hundredth)

Solve the following compound
inequality.
d – 4 > 3 or d – 4 < 1
Answer:
(-∞, 5 U 7 , ∞)
Step-by-step explanation:
Given the inequality expressions
d – 4 > 3 or d – 4 < 1
For d - 4 > 3
Add 4 to both sides
d-4 + 4 > 3 + 4
d > 7
7 < d
this means that d is greater than 7,
(7 , ∞)
For d - 4 < 1
Add 4 to both sides
d - 4 + 4 < 1 + 4
d < 5
This means d is less than 5
(-∞, 5)
The required solution is (-∞, 5 U 7 , ∞)

Find the measure of the exterior 1.
A. 110°
B. 10°
C. 70°
D. 150°
don’t give me a link.
Answer:
You answer is C. 70 degrees.
Step-by-step explanation:
Since you have the two other Interior values, you know that when you add them (40+30), and then subtract it from 180, you will find that the other Interior angle is 110 degrees.
Now, an interior and exterior angle must add up to 180 degrees to be a correct angle. Since you know that the interior one is 110, you can figure out that the exterior angle will be 70 degrees.
110+x=180
110+70= 180
180=180

WILL GIVE 30 POINTS TO WHOEVER SOLVES THIS
Answer:
142 square meters
Step-by-step explanation:
Big rectangle Area = LxW = 18 x9= 162
White triangle Area A = (ab)/2 legs 5 and 8 ( 18-10= 8 )
= (5x8)/ 2 = 20
Subtract white triangle from green rectangle
162-20 = 142
OR
area left rectangle LxW 10x9 = 90
area right rectangle LxW 4x8 =32
area green triangle ( sides 5 an8 ) (ab)/2 = 20
90+32+20 = 142

Given x^2 + y^2 = 16, find
name:
center:
Domain:
Range:
x-int
y-int
Answer:
see explanation
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 16 ← is the equation of a circle
centre (0, 0 ) and r = [tex]\sqrt{16}[/tex] = 4
The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )
and intercepts the y- axis at (0, - 4 ) and (0, 4 )
Domain is - 4 ≤ x ≤ 4
range is - 4 ≤ y ≤ 4
x- intercepts are x = - 4, x = 4
y- intercepts are - 4, 4
Answer:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 16 ← is the equation of a circle
centre (0, 0 ) and r = \sqrt{16}16 = 4
The circle therefore intercepts the x- axis at (4, 0 ) and (4, 0 )
and intercepts the y- axis at (0, - 4 ) and (0, 4 )
1/3x+8=12 what does x equal and show work
Answer: x = 12
Step-by-step explanation:
subtract 8 on both sides (12-8=4)
now we have 1/3x = 4
multiply 3 on both sides (4 x 3 = 12)
now we have x = 12
What is the circumference of the circle?
Answer:
The circumference of a circle is the distance around the outside of the circle
Hope It Helps :)
Step-by-step explanation:
Answer:
Circumference of the circle or perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of circle defines the region occupied by it. If we open a circle and make a straight line out of it, then its length is the circumference. It is usually measured in units, such as cm or unit m.
When we use the formula to calculate the circumference of the circle, then the radius of the circle is taken into account. Hence, we need to know the value of the radius or the diameter to evaluate the perimeter of the circle.
Circumference of a Circle Formula
The Circumference (or) perimeter of a circle = 2πR
where,
R is the radius of the circle
π is the mathematical constant with an approximate (up to two decimal points) value of 3.14
Again,
Pi (π) is a special mathematical constant; it is the ratio of circumference to diameter of any circle.
where C = π D
C is the circumference of the circle
D is the diameter of the circle
For example: If the radius of the circle is 4cm then find its circumference.
Given: Radius = 4cm
Circumference = 2πr
= 2 x 3.14 x 4
= 25.12 cm
Let f(x) = x + 2 and g(x) = x + 4.
Find f(g(f(2)).
Brainliest 15 points
Answer:
10
Step-by-step explanation:
Let's find f(2) first.
f(2) = 2 + 2 = 4
This means it would be f(g(4)).
Then let's find g(4).
g(4) = 4 + 4 = 8
Then, this means f(8).
f(8) = 8 + 2 = 10
