The measure of EFH is twice the measure of GFH. What is the
degree measure of GFH?
I NEED HELP ASAP
Answers
Answer:
30° = m∠GFH
Step-by-step explanation:
Since ∠EFH and ∠GFH are complementary, the sum of their measures i 90.
Let x = m∠GFH
2x = m∠EFH
m∠GFH + m∠EFH = 90
x + 2x = 90
3x = 90
x = 30° = m∠GFH

10) A circle has center at (-5, 3) and passes through the point (-1, 3).
a) Give the radius of the circle.
b) Give the equation of the circle described.
Answers
b) (x+5)^2+(y-3)^2=4^2
The distance between the x values in the center point and a point included in the graph will give you the radius.
The x values are 4 units apart (-5 to -1) so your radius is 4 units
Circle formula:
(x-h)^2+(y-k)^2=r^2
Where (h,k) is the center point and r is the radius
Replace h with -5, k with 3, and r with 4 to get equation listed in answer above

Find the value of x.
Answers
Answer:
x= 37.5°
Step-by-step explanation:
∠CBD
= 180° -75° (adj. ∠s on a str. line)
= 105°
∠BCD= ∠BDC (base ∠s of isos. △BCD)
∠BCD= x
∠BCD +∠BDC +∠CBD= 180° (∠ sum of △BCD)
x +x +105°= 180°
2x= 180° -105°
2x= 75°
x= 37.5°
Alternative working:
∠BDA= (180° -75°) ÷2 (base ∠s of isos. △ABD)
∠BDA= 52.5°
∠BDA +∠BDC= 90°
52.5° +x= 90°
x= 90° -52.5°
x= 37.5°

Based on this information, which of the following statements is true?
A. The volume of the larger cylinder is 2 times the volume of the smaller cylinder.
B. The volume of the larger cylinder is 4 times the volume of the smaller cylinder.
C. The volume of the larger cylinder is 8 times the volume of the smaller cylinder.
D. The volume of the larger cylinder is 6 times the volume of the smaller cylinder.
Answers
The true statement is The volume of the larger cylinder is 8 times the volume of the smaller cylinder.
The correct option is (C)
What is Volume of cylinder?The volume of cylinder is, V= πr²h.
Volume of large cylinder,
= πr²h
= πd²(2h)
= 2hπd²
Volume of large cylinder,
= πr²h
= π(d/2)²(h)
= πd²h/4
= 2πd²h/8
Hence, The volume of the larger cylinder is 8 times the volume of the smaller cylinder.

Calculate the area of triangles using two different methods. figures are now drawn to scale.
Answers
Answer:
the formula is base times hight divided by two so use the formula to sovle the problem
Step-by-step explanation:
The area of the triangles given are 52.5 feet² and 369 inches² respectively.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
The basic formula to calculate the area of a triangle is,
Area = [tex]\frac{1}{2}[/tex] × base × height
1. Base = 12 + 3 = 15 feet
Altitude/height = 7 feet
Area = [tex]\frac{1}{2}[/tex] × 15 × 7 = 52.5 feet²
2. Calculating the area of two separate triangles and then adding it,
Area = ([tex]\frac{1}{2}[/tex] × 32 × 18) + ([tex]\frac{1}{2}[/tex] × 9 × 18)
= 288 + 81
= 369 inches²
Hence the area of the two figures is 52.5 feet² and 369 inches² respectively.

Which values for A and B will create infinitely many solutions for this system of equations? A x minus y = 8. 2 x + y = B.
Answers
Answer:
A = -2
B = -8
Step-by-step explanation:
A system of equations has infinitely many solutions when both equations are exactly the same equation, then both graphs intersect in infinitely many points, meaning that the system has infinitely many solutions.
Then if we have the equations:
A*x- y = 8
2*x + y = B
We want to find A and B such that both equations are exactly the same thing.
Notice that in the first one we have negative y, while in the second we have positive y.
Then A needs to be minus the coefficient that multiplies x in the other equation, this means that:
A = -2
And B needs to be minus the corresponding therm in the other equation, then B = -8.
Then the system becomes:
-2*x - y = 8
2*x + y = -8
We can see that one equation is -1 times the other, so if we write both of them as linear equations in the slope-intercept form, we get:
y = -8 - 2*x
y = -8 - 2*x
So both equations are exactly the same thing, meaning that we have infinitely many solutions.
Joseph has only nickels and quarters in his piggy bank. He has 62 coins total for a
combined value of $11.10. How many nickels does Joseph have?
Answers
9514 1404 393
Answer:
22 nickels
Step-by-step explanation:
Let n represent the number of nickels in Joseph's piggy bank. Then the number of quarters is 62-n. The total value is ...
0.05n + 0.25(62 -n) = 11.10
-0.20n + 15.50 = 11.10 . . . simplify
4.40 = 0.20n . . . . . . . . . . add 0.20n-11.10
4.40/0.20 = n = 22

The initial value of the exponential function is 2.
What are Exponential Functions?Exponential functions are functions where the independent variable, x is in the exponent.
Given is the graph of the exponential function.
The initial value of the exponential function is the value of the function when the value of the independent variable is 0.
The general form of exponential function is y = abˣ
When x = 0, y = a, which is the initial value.
Here, when x = 0, the graph touches the Y axis.
y = 2
Hence the initial value is 2.

Beverly makes wreaths to sell for the fall season. She picked 430 pine cones from the wooded area near her house. If she uses 23 pine cones per wreath, how many wreaths can she make?
From the above question:
23 pine cones = 1 wreath
430 pine cones = x wreaths
Cross Multiply
23 pine cones × x wreaths = 430 pine cones × 1 wreath
x wreaths = 430 pine cones × 1 wreath/23 pine cones
x wreaths = 18.695652174 wreaths
