Two sides of a triangle measure 10 inches and 10.9 inches. The included angle between these sides is 65°. What is the approximate measure of the third side of the triangle?
Answers
Answer:
9.9inches
Step-by-step explanation:
From the attachment, the opposite side is debited as "x" while the Hypotenuse is 10.9inches, we can find the third side by using trigonometry
From trigonometry, Sin(x)= opposite/Hypotenuse
Sin(65)=X/10.9
X= Sin(65) ×10.9
X=0.9063×10.9
=9.8688
Hence the third side of the triangle is approximately 9.9inches

The Augello family is driving from Columbus to St. Louis at a constant rate of 65 miles per hour. The distance between the two cities is 420 miles. Write an equation in slope-intercept form to represent the distance y in miles remaining after driving x hours.
Answers
Answer:
[tex] y = -65x + 420 [/tex]
Step-by-step explanation:
Slope-intercept form equation is given as [tex] y = mx + b [/tex]
Where,
y = distance remaining
x = hours driven
m = slope/constant rate. In this case, the value of m would be -65. This means the distance will reduce at a constant rate of 65 miles per hour.
b = y-intercept, which is the initial value or the distance between the cities = 420
Plug in the values into the slope-intercept equation, to represent the distance y in miles remaining after driving x hours. You would have:
[tex] y = -65x + 420 [/tex]
The equation in slope intercept form is [tex]y =-65x + 420[/tex]
Linear functionA linear function is a function whose value changes at a constant rate.
The given parameters are:
Distance = 420 milesRate = -65 miles per hourA linear function is represented as:
[tex]y = mx + c[/tex]
Where
m represents the ratec represents the initial value i.e. the distanceSo, the function becomes
[tex]y =-65x + 420[/tex]
Hence, the equation in slope intercept form is [tex]y =-65x + 420[/tex]

Step-by-step explanation:
Step one:
charges per hour= $60
We are told that the electrician earned $350
for a job that took 5hours
The linear equation to represent his earnings is
let the flat fee be x
C=60t+x------------1
so for C=$350

350=60(5)+x
350=300+x

a flagpole 6.3m is driven 1.4m long into the ground .what fraction of the pole is above the ground
Answers
Answer:
4.9/6.3= .777777... , a simplified fraction form of this would be 7/9.
Step-by-step explanation:
Fraction 7/9 of the flagpole is above the ground
If a flagpole 6.3m long is driven 1.4m into the ground, then the fraction of the pole that is above the ground is 6.3m - 1.4m = 4.9m / 6.3m = 49/63 = 7/9.
To calculate the fraction of the pole that is above the ground, we need to subtract the length of the part of the pole that is driven into the ground from the total length of the pole. This gives us 4.9m. We then divide this length by the total length of the pole to get the fraction 7/9.
In other words, 7/9 of the flagpole is above the ground. This means that if we cut the flagpole into 9 equal pieces, 7 of those pieces would be above the ground and 2 of those pieces would be below the ground.

Answers
Answer: $3 : $4 or 3 : 4
Step-by-step explanation: To find the ratio of the cost of lemon juice in salad dressing, you’ll have to replace $13.50 or 13.5 to (135/10), which doesn’t affect the solution. Next, simplify (135/10) to get 27/2. After, divide 27/2 by 18, which is the other part of the ratio. (27/2 ÷ 18) Your final answer or result should end up as 3/4 but since we’re dealing with fractions 3:4, which is the simplified form of $13.50 : $18.00.
