Answer:
102 cm²232 in²40.46 ft²480 mm²Step-by-step explanation:
The first three cuboid prisms all use the same area formula:
A = 2(LW +H(L+W))
__
1. A = 2(3·3 +7(3+3)) = 2(9 +42) = 102 . . . cm²
2. A = 2(2·8 +10(2 +8)) = 2(16 +100) = 232 . . . in²
3. A = 2(4.9·3 +0.7(4.9 +3)) = 2(14.7 +5.53) = 40.46 . . . ft²
__
4. The area of this prism is the total of the area of the two triangular bases and the areas of the rectangular faces. For triangle legs a, b and hypotenuse c, and prism depth d, the area formula can be written as ...
A = ab +d(a+b+c)
A = (8 mm)(15 mm) +(9 mm)(8 mm + 15 mm + 17 mm)
A = (120 +9(40)) mm² = 480 mm²

Answer:
(a) (2x +36)° +(3x +14)° = 90°
(b) ∠C = 38°; ∠D = 52°; ∠E = 90°
Step-by-step explanation:
(a) Two acute angles are marked in a right triangle. We know the sum of angles in a triangle is 180°, so if one of those angles is 90°, the sum of the other two angles must be 90°. We can use that fact to write and equation for x.
(2x +36)° +(3x +14)° = 90°
__
(b) We can collect terms, subtract 50 and ...
5x +50 = 90 . . . . . . . collect terms, divide by °
5x = 40 . . . . . . . . . . subtract 50
x = 8 . . . . . . . . . .. divide by 5
∠C = (3x +14)° = (3·8 +14)° = 38°
∠D = (2x +36)° = (2·8 +36)° = 52°
∠E = 90°
_____
Angle E is marked as a right angle by the little square in that corner. The measure of a right angle is 90°, by definition.

Ox>-3
Ox<-3
0x<-7
Ox>-7
Answers
Answer:
x > -3
Step-by-step explanation:
-3x + 6 < 15
-3x < 15 - 6
-3x < 9
-x < 3
x > -3
A. x > -3
Step-by-step explanation:
Step 1: Subtract 6 from both sides.
−3x + 6 − 6 < 15 − 6
−3x < 9
Step 2: Divide both sides by -3.
−3x/−3 < 9/−3
x > −3
a baseball coach collected data to analyze the free throw shooting percentages of players during a game and during practice. The equation y=0.9x-1 is a line of best fit for the data, where x is the practice shooting percentage and y is the game shooting percentage. Based on the equation, what will be the approximate shooting percentage in a game for a player with a practice shooting percentage of 88?
Answers
Step-by-step explanation:
so fill in 88 where the x is so
y = 0.9 (88) - 1
y = 78.2

A= B= b= what’s the answer i been trying to solve all day
Answers
Answer:
Step-by-step explanation:
We are given the triangle ABC and told to find ∠A, ∠B, and side b. Also we are told that side c= 54 . side a=64 and ∠C = 32°
we need law of sines a / sin A = b / sin B = c / sin C
let's use law of sines to find the other angles
64 / sin A = 54 / sin(32)
I'm just going to swap the fractions on both sides , just to make it easier
sin A / 64 = sin(32) / 54
∠A = arcSin(64 * sin(32) / 54)
∠A = 38.9066°
∠B + ∠A + ∠C = 180
∠B = 180 - 32 - 38.9066
∠B = 109.0934°
let's find side b now
sin B / b = sin(32) / 54
sin(109.0934°) / b = sin(32) / 54
54 * sin(109.0934°) / sin(32) = b
96.2963 = b

Answers
Answer:
94.99
Step-by-step explanation:
Hi,
The formula to find the area of a circle is: A = πr²
So...
A = 3.14 (r)²
The radius of the circle is 5.5 because half of the diameter is the radius.
A = 3.14 (5.5)²
A = 3.14 (30.25)
A = 94.985 rounded is 94.99

For f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a. (fog)(x); b. (gof)(x); c. (fog)(2); d. (gof)(2)
Answers
Answer:
See answer below
Step-by-step explanation:
Given the functions f(x) = 5x – 3 and g(x) = 2x2 - 5, find the following functions.
a)(fog)(x) = f(g(x))
f(g(x)) = f(2x^2-5)
f(g(x)) = 5(2x^2-5) - 3
f(g(x)) = 10x²-25-3
f(g(x)) = 10x² - 28
b) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 2(25x²-30x+9)-5
g(f(x)) = 50x²-60x+18-5
g(f(x)) = 50x²-60x+13
c)(fog)(2) = f(g(2))
f(g(x)) = f(2x^2-5)
f(g(2)) = 10(2)² - 28
f(g(2)) = 10(4)-28
f(g(2)) = 12
d) g(f(x)) = g(5x-3)
g(f(x)) = 2(5x-3)²-5
g(f(x)) = 50x²-60x+13
g(f(2)) = 50(2)²-60(2)+13
g(f(2)) = 200-120+12
g(f(2)) =80+12
g(f(2)) = 92
