Answer:
The answer would be D, hope this helps
helppppppppppppppppppp
Answer:
B
Step-by-step explanation:
You just substitute the values in for A and B and then you simplify
The 10 A would be 10x17 which is 170 and then plus B, which we know is 12, so it would equal 182
hope this helped
Answer:
182
Step-by-step explanation:
First, plug in 17 for a
10·17+b=170+b
Then plug in 12 for b
170+12=182
There you go!
182
For an equation that represents as a function of the set of all values taken on by the ________ variable is the domain, and the set of all values taken on by the ________ variable is the range
Answer:
Independent [tex]\to[/tex] Domain
Dependent [tex]\to[/tex] Range
Step-by-step explanation:
Required
Fill in the gaps
A function is represented as:
[tex]y = f(x)[/tex]
Where, x represents the set of input values (or the domain) and y, the set of output values (or the range).
Since the input values are represented by x, they are referred to as the independent variables while the output values are referred to as the dependent values because they depend on the x values for their output.
Juan is a teacher and takes home 68 papers to grade over the weekend. He can grade at a rate of 6 papers per hour. How many papers would Juan have remaining to grade after working for 7 hours?
Answer:
26 papers
Step-by-step explanation:
Well this is pretty straight forward
if he can grade 6 papers an hour
we just multiply 6 by 7 to get how many papers he graded in 7 hours
6*7= 42
now we subtract 42 from 68 to get how many papers are left to be graded
68-42=26
26 papers are left

Find the length of arc XW. Round your answer to the nearest hundredth.
Answer:
15.08 m
Step-by-step explanation:
The angle XZW :
XZW + 108° = 180°
XZW = 180° - 108°
XZW = 72°
Length of an arc = θ / 360 * πd
d = diameter = XV = 24
Length of arc XW = (72/360) * π * 24
Length of arc XW = 15.0796
Length of XW = 15.08 m
Answer:
15.08

ADD root of 5 +2 root of 2 and root of 2 - 5root of 3
Add :
→ (√5 + 2√2) & (√2 - 5√3)
Putting the sign of plus at the place of &.→ (√5 + 2√2) + (√2 - 5√3)
Removing the brackets.
→ √5 + 2√2 + √2 - 5√3
→ √5 + (2 + 1)√2 - 5√3
→ √5 + 3√2 - 5√3
Therefore, the required answer is √5 + 3√2 - 5√3.
PLs, help me with this math question, and please answer if you only know it.
Answer:
Step-by-step explanation:
This is quite a doozy, so try and follow along. If you don't know your circle stuff well, it will be more difficult for you to understand how all this comes together.
First, we were given that angle CBD = 55. That means that angle CED is also 55 since they are both inscribed angles and they both intercept the same arc, arc CD. Angle BFC is congruent to angle 5 because they are vertical and vertical angles are congruent, so that means that triangle BFC is congruent to triangle EFD because of Angle-Angle-Side. Now that we got that out of the way, let's move on. We will come back to that in a bit.
Angle 1 intercepts arc BE and since angle 1 is an inscribed angle, it is half the measure of its intercepted arc. Therefore,
∠1 = 25° ; angle BCE also equals 25 degrees since they are both inscribed and they both intercept the same arc (again, arc BE).
If angle BCE is 25, and angle CBD is 55, then angle F, by the Triangle Angle Sum Theorem, must equal 180 - 25 - 55 = 100. And if Angle F = 100, then
∠5 = 100° . Angles 4 and 5 are supplementary, therefore,
∠4 = 80°
Since angle CBD was given as 55 and is an inscribed angle for arc CD, then arc CD is twice the measure of its inscribed angle and arc CD is 110 degrees. Angle 6, then, is one-half the difference of arc CD and arc BE so
∠6 = 30°
Angles 2 and 3 are congruent since they are both inscribed and they both intercept the same arc (arc DE); and since triangles BFC and EFD are congruent, by CPCTC, sides BF and EF are congruent...which means by the IsoscelesTriangle Theorem, angle 2 and angle BEC are congruent. 180 - 80 = 100 and divide that in half to get that
∠2 ≅ ∠3 = 50°
Lastly, angle 7 is half the measure of its intercepted arc (arc BE, given as 50), therefore,
∠7 = 25°

The circumference of the circle is 69.1 cm.
What is circumference?The circumference of a circle refers to the measure of its boundary. If we open a circle and measure the boundary just like we measure a straight line.
Given that a circle with radius 11 cm, we need to find the circumference of the circle,
Circumference = π × 2 × radius
= 3.14 × 2 × 11
= 69.1 cm
Hence, the circumference of the circle is 69.1 cm.

Answer:
i think its 54. i might be incorrect.
Step-by-step explanation:
Answer:
54º
Step-by-step explanation:
This really cannot be determined because the combined angle is not marked as 90º
let's assume it is 90º
(7x + 12) +(2x + 24) = 90
Combine like terms
9x + 36 = 90
Subtract 36 from both sides
9x = 54
Divide both sides by 9
x = 6
-----------------------
7(6) + 12 = 54º
2(6) + 24 = 36º
54º is the larger angle

Jack tool out a 6-year loan for $25,000 to purchase a boat at a 4.5% interest rate. If the interest is compounded monthly, what will he have paid total over the course of the loan?
Answer:
A = $32,732.58
A = P + I where
P (principal) = $25,000.00
I (interest) = $7,732.58
Step-by-step explanation:
Given data
Time= 6 years
Principal= $25,000
Rate= 4.5%
First, convert R as a percent to r as a decimal
r = R/100
r = 4.5/100
r = 0.045 rate per year,
Then solve the equation for A
A = P(1 + r/n)^nt
A = 25,000.00(1 + 0.045/12)^(12)(6)
A = 25,000.00(1 + 0.00375)^(72)
A = $32,732.58
