Step-by-step explanation:
what is the area of triangle EDF?
Answer:
4.5
Step-by-step explanation:
∠BAC ~ ∠EDF means that the triangles are similar. So the legs of the triangle share the same proportions, even if the sizes are different.
Since they share the same proportions, the same operations can be performed on each base to find the area.
The answer can be found with the knowledge that the area of a triangle is half of the height * width. You know the width of ∠BAC is 4, and the area is 8, so 16 (the area doubled) / 4 is the height. The width and height of ∠BAC are the same, and since the proportions are also the same, the width and height of ∠EDF are both 3. So the area is the width (3) times the height (3) divided by 2.
3*3 = 9
9/2 = 4.5
So the area is 4.5

if a student took a test three times and got 90 all three times, what is the score needed to bring down the average to 88
Answer:
The score of the fourth test should be 82
Step-by-step explanation:
Let the score of the fourth test be x.
(3×90+x)/4=88
270+x=352
x=82

How would someone Algebraically determine X-Y intercepts?
Answer:
y-int: -6
x-int: -2/5 and 3
Step-by-step explanation:
you can find the y-intercept by substituting zero in for every 'x' in the equation;
y = 5(0) - 13(0) - 6
y = -6
to find the x-intercept(s), factor the trinomial by trying to find a pair of factors that multiply to 6 and add to -13; the factors that work are:
(5x + 2)(x - 3)
now set each factor equal to zero and solve for 'x':
5x + 2 = 0
5x = -2
x = -2/5
x - 3 = 0
x = 3

An angle measures 14º more than the measure of its supplementary angle.
What is the measure of each angle?
T
Answer:
83 and 97
Step-by-step explanation:
Supplementary angles are two angles with a sum of 180 ∘
small angle = x
large angle = x+14
x + (x+14) = 180
2x +14 = 180
2x= 166
x = 83
large = 83 +14 = 97
83+97 = 180
PLEASE ANSWER THIS ASAP
Answer:
[tex]\text{C. }98^{\circ}[/tex]
Step-by-step explanation:
Opposite angles in any quadrilateral circumscribed by a circle always add up to 180 degrees.
(Opposite angles in a cyclic quadrilateral are always supplementary).
Thus,
[tex]82+\angle D=180,\\\angle D=\boxed{\text{C. }98^{\circ}}[/tex]
can someone help with this? ive been doing the other ones correctly but this one has me stumped
RS is tangent to the given Circle.
We know that, radius from the center of the circle to the point of tangency is perpendicular to the tangent line.
So,
∠CRS = 90°
We also know that, sum of all angles inside a triangle is 180°.
So,
∠CRS + ∠CSR + ∠RCS = 180°
90° + 46° + x = 180°
136° + x = 180°
x = 180° - 136°
x = 44°
So, the value of x = 44°.

Y=x3 is that a function?
Answer:
yes
Step-by-step explanation:
y(x) is even or odd according as y(−x)=±y(x) . Here, #y(-x)=-(-x)^3=-(-x^3)=x^3=-y(x). So, y is an odd function of x.

8. A cellphone company charges $29.99 per month for the first 500 minutes of calls and $0.30 a minute for any calls over the 500-minute limit. . Last month Demetria made 615 minutes of calls on her cellphone. Excluding tax, what were the total charges for her cellphone calls last month? A. $29.99 B. $34.50 C. $64.49 D. $184.50
Answer:
C) $64.49
Step-by-step explanation:
let 'x' = #minutes
cost = 29.99 + 0.3(x-500)
= 29.99 + .3(115)
= 29.99 + 34.50
= $64.49

find the area of this figure
Answer:
170 in²
Step-by-step explanation:
This trapezoid is broken up into two shapes: a triangle and a parallelogram.
The formula for area of a triangle is b (base) × h(height) ÷ 2.
The base of the triangle is 4 and the height is 10.
b (base) × h(height) ÷ 2
10 × 14 ÷ 2 = 70
-------------------------------------------------------------------------------------------------------------
The formula for area of a parallelogram is b (base) × h(height).
The base of the parallelogram is 10 and the is 10 as well.
b (base) × h(height)
10 × 10 = 100.
-------------------------------------------------------------------------------------------------------------
Lastly, add both areas.
100 + 70 = 170
Therefore, the area of this figure is 170 in².

What is the inverse of the function f(x) = 2x + 1?
o hex) = x-1
h(x) =
10x) = 3x-2
h(x) = 5x + 2
Answer:
y = x /2 - 1/2
Step-by-step explanation:
y = h(x)
y = 2x + 1 Interchange x and y
x = 2y + 1 Subtract 1
x - 1 = 2y Divide by 2
x/2 - 1/2 = y
y = x/2 - 1/2
