Answer:
The value of x is 9
Step-by-step explanation:
The measure of the exterior angle at a vertex of a triangle equals the sum of the measures of the two opposite interior angles to this vertex
In the given figure
∵ ∠DFG is an exterior angle at vertex F
∵ The angles of measures (5x - 7) and 89° are the opposite interior
angles to the vertex F
∴ m∠DFG = (5x - 7) + 89
∵ m∠DFG = 14x + 1
→ Substitute it in the equation above
∴ 14x + 1 = 5x - 7 + 89
→ Add the like terms in the right side
∵ 14x + 1 = 5x + 82
→ Subtract 1 from both sides
∵ 14x + 1 - 1 = 5x + 82 - 1
∴ 14x = 5x + 81
→ Subtract 5x from both sides
∴ 14x - 5x = 5x - 5x + 81
∴ 9x = 81
→ Divide both sides by 9
∴ x = 9
∴ The value of x is 9

x = [tex]\sqrt{66}[/tex]
Step-by-step explanation:
This is using the altitude on hypotenuse theorem
(leg of big Δ )² = ( part of hypotenuse below it ) × ( whole hypotenuse )
x² = 6 × (6 + 5) = 6 × 11 = 66 ( take square root of both sides )
x = [tex]\sqrt{66}[/tex]

Answers
Answer:
$1.67 per square foot
Step-by-step explanation:
First find the area of the carpet.
A=l times w
A-10(12)
A=120 square feet

Find the equation of the line with slope = -7 and passing through (-7,51). write your equation in the form y=mx+b
Answers
Answer:
y = -7x + 2
Step-by-step explanation:
Since we do not have the y-intercept (or, when the x is 0) We will use the Slope Form Formula (y - y1 = m(x - x1)) to find the Slope Intercept Form Formula (y = mx + b)
Point: (-7,51)
Slope: -7
y - y1 = m(x - x1)
y - 51 = -7(x - (-7))
y - 51 = -7(x + 7)
y - 51 = -7x - 49
y = -7x - 49 + 51
y = -7x + 2

Terry has nuts and bolts the ratio of the number of nuts to the number of bolts is 7:9 if Terry has 36 bolts how many nuts does Terry have
Answers
Let the number of nuts and bolts be 7x and 9x respectively.
Number of bolts = 36[tex] \tt { \therefore{9x = 36}}[/tex]
Solving the formed equation :
[tex]: \implies \sf 9x = 36 \\ \\ [/tex]
By dividing both sides by 9 .[tex]: \implies \sf x = \cancel{\dfrac{36}{9} }[/tex]
By dividing 36 and 9 by 9.[tex]: \implies{\underline {\boxed{ \tt x = 4 }}}[/tex]
[tex]\huge {\therefore}[/tex] The number of number of nuts are 7x = 7*4 = 28.

The three angles of a triangle measure 2x – 6, 3x + 5, and 2x + 20. What is the measure of the smallest angle in degrees?
Answers
Answer:
The smallest angle is 40.
Step-by-step explanation:
2x-6+3x+5+2x+20=180
7x+19=180
7x=180-19
7x=161
x=161/7
x=23
Now,
= 2x-6
= 2×23-6
= 40
= 3x+5
= 3×23+5
=74
=2x+20
=2×23+20
=66
The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t. Which is an equivalent equation solved for a?
StartFraction f minus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.– v = a
StartFraction f plus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.+ v = a
Answers
Answer:
StartFraction f minus v Over t
EndFraction =a
Step-by-step explanation:
The equation for acceleration is a= f-v
-----
t
Rearrange f=v+at
solve for a
f= v+at minus v
-v -v
get a by itself. multiplication is happening a between and t so divide
f-v=at
--- ---
t t
a= f-v
----
t

A dinner costs $4.99. Joanie plans to tip the waitress 15%. How much is the tip? (TEKS
7.4D-R)
A $0.15
B $0.75
C $5.14
D $5.74
Answers
Answer:
The tip given to waitress is $0.75. Option B is correct.
Step-by-step explanation:
Cost of Dinner = $4.99
Tip to be given to waitress = 15%
We need to find the cost of tip.
The tip would actually be given 15% of the dinner cost i,e
Tip = 15% of 4.99
Solving to find tip cost
[tex]Tip = 15\% \ of \ 4.99\\Tip=15\% \times 4.99\\Tip=\frac{15}{100} \times 4.99\\Tip=0.75[/tex]
So, the tip given to waitress is $0.75. Option B is correct.
