Find the answer for m∠EFD
Given:
In triangle DEF, [tex]DE = EF[/tex] and [tex]m\angle 98^\circ[/tex].
To find:
The measure of angle EFD.
Solution:
In triangle DEF,
[tex]DE = EF[/tex] (Given)
It means triangle DEF is an isosceles triangle.
[tex]m\angle EDF=m\angle EFD[/tex] (Base angles of an isosceles triangle are equal)
Using angle sum property in triangle DEF, we get
[tex]m\angle DE F+m\angle EFD+m\angle EDF=180^\circ[/tex]
[tex]98^\circ +m\angle EFD+m\angle EFD=180^\circ[/tex]
[tex]2m\angle EFD=180^\circ-98^\circ[/tex]
[tex]2m\angle EFD=82^\circ[/tex]
Divide both sides by 2.
[tex]m\angle EFD=\dfrac{82^\circ}{2}[/tex]
[tex]m\angle EFD=41^\circ[/tex]
Therefore, the measure of angle EFD is 41 degrees.

Please help it’s algebra!!!!!!
Answer:
a). -6x³ - 12x² b). -12 c). 12
Step-by-step explanation:
a). (g x f)(x) can also equal f(g(x))
= f (2x +4)
= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))
g(-1) = 2(-1) + 4
= -2 + 4
= 2
f(2) = -3x²
= -3(2)²
= -12
c). g(h(3))
h(3) = 3x-1/2
= 3(3) - 1 / 2
= 4
g(4) = 2x + 4
= 2(4) + 4
= 12

Andrew is paid £250 a week. Each week, he shares his pay with his sister in the ratio 3 : 2 saves 12% of his share. How many weeks will it take Andrew to save £360?
Answer:
20 weeks
Step-by-step explanation:
The computation of The number of weeks it will take to save £360 is shown below:
Now $250 should be divided into a ratio of 3:2
He keeps = 150
ANd, he gives her = 100
As he saves 12% of his share
i.e.
= 12% of 150
= 18
Now the number of weeks would be
= 360 ÷ 18
= 20 weeks

PLS HELP Select all the expressions that represent the total area of this rectangle.
Answer:
E and D
Step-by-step explanation:
The area of a rectangle is length x width. In this case, that's (12+s) x 1/3
This can be re-written as 1/3(12+s)
D is 1/3s + 4 which is what happens when you multiply 1/3 by 12 which = 4 and multiply 1/3 by s which = 1/3s. So the answer is 1/3s+4.
Mr. Wright needs to buy a water tank for his classroom. The tank must fit inside a storage box that is shaped like a cube with side lengths of 20 feet. Water tanks are available in cylinders, cones, square pyramids, and spheres. Mr. Wright wants to buy the tank that has the largest capacity… What shape should he buy?
Answer:
square pyramids
Step-by-step explanation:
Square pyramids because they have corners and the storage box is shaped like a cube. If he gets things with rounded edges, then there will be empty space between each water tank.

Which of these is the algebraic expression for "4 times the sum of 2 and y?"
a 4 ⋅ 2 + y
b 4(2 + y)
c 2 + 4 ⋅ y
d 2(4 + y)
Answer:
b
Step-by-step explanation:
The sum of 2 and y is 2 + y, then 4 times this sum is
4(2 + y) → b

Answer:
75 degrees
Step-by-step explanation:
All the interior angles of a triangle add up to 180 degrees. Knowing this, we can construct the following equation:
180=65+40+x
180=105+x
Subtract both sides by 105
180-105=105+x-105
75=x
Therefore, angle C has a measure of 75 degrees.

Find the inverse equation of y=3x-12
Answer:
[tex]f {}^{ - 1}(x) = \frac{x}{3} + 4[/tex]
Step-by-step explanation:
[tex]y = 3x - 12[/tex]
Flip the variables then solve for y
[tex]x = 3y - 12[/tex]
[tex] \frac{x}{3} = y - 4[/tex]
[tex] \frac{x}{3} + 4 = y[/tex]
[tex]f {}^{ - 1} (x) = \frac{x}{3} + 4[/tex]
Mrs. Williams put $500 into a retirement account that earns 4% interest. How long will it take for there to be $3,500?
What is the A value?
What is the B value?
What is the equation and answer?
9514 1404 393
Answer:
A = 500
B = 1.04
49.6 years
Step-by-step explanation:
We assume your 'A' and 'B' refer to parameters in an exponential formula of the form ...
y = A·B^x
In this form, A is the initial investment value, $500. B is the growth factor, 1+4% = 1.04, assuming interest is compounded annually. We want to find x such that y=$3500.
3500 = 500·1.04^x . . . . . fill in known values
7 = 1.04^x . . . . . . . . . . . . . divide by 500
log(7) = x·log(1.04) . . . . . . take logarithms
x = log(7)/log(1.04) ≈ 49.61 . . . . divide by the coefficient of x
It will take about 49.6 years for there to be $3500 in Mrs. Williams's account.
If your driving 60miles an hour and you drive for 1hour how far do you travel?
Answer:
60 miles
Step-by-step explanation:
There are two ways to solve this:
1. They tell you that you drive at 60 miles an hour, so , in an hour, you drive 60 miles.
2. Is the way you should use in the future:
Distance = speed * time
Substitute the speed and times.
Distance = 60 * 1
Thus, you drive 60 miles in one hour
The distance that should be traveled be 60 miles
As we know that
[tex]Speed = \frac{distance}{time}[/tex]
Here
speed be 60 miles per hour
And, the time should be one hour
So, the distance should be
[tex]= 60\ miles\ per hour \times one\ hour[/tex]
= 60 miles
Therefore the distance that should be traveled be 60 miles

A rectangular piece of paper with length 39 cm and width 20 cm has two semicircles cut out of it, as shown below.Find the area of the paper that remains. Use the value 3.14 for π , and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
The area of the piece of paper is 466 cm²
Step-by-step explanation:
First you would want to find the area of the rectangle
39x20=780 cm²
Both semi-circles are the same, so you can just find the area of the whole circle
The diameter is 20 cm so you would use 10 as the radius
A=πr²
A=3.14x10²
A=3.14x100
A=314
Then you have to subtract the area of the circle from the area of the rectangle.
780-314=466
The area of the piece of paper is 466 cm²
The rectangle shown has a perimeter of 98 cm and the given area. Its length is 7 more than 5 times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
35 is its width and 63 is its length.
Step-by-step explanation:
7 x 5 = 35 and 98 - 35 equals 63 which is the length.
