In ΔABC, m ∠ A = ( 3 x + 1 ) ∘ m∠A=(3x+1) ∘ , m ∠ B = ( x + 14 ) ∘ m∠B=(x+14) ∘ , and m ∠ C = ( 4 x + 5 ) ∘ m∠C=(4x+5) ∘ . What is the value of x ? x?
Answer:
x = 20
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180
3x + 1 + x + 14 + 4x + 5 = 180, that is
8x + 20 = 180 ( subtract 20 from both sides )
8x = 160 ( divide both sides by 8 )
x = 20

The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 3 in. What are actual dimensions of the kitchen
Answer:
5feet by 4/3feet
Step-by-step explanation:
The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 /3 in. What are actual dimensions of the kitchen.
From the question, we were given the conversation rate of 1/4 in = 1/2 ft In the model,
To get actual dimensions of the kitchen if the kitchen measures 2 1/2 by 2 3 in. Then
✓Let us convert 2 1/2in to feet first= 5/2in as improper fraction.
If 1/4 in = 1/2 ft
5/2in = x ft
Then cross multiply, we have
(5/2×1/2)= 1/4 × X
5/4 = 1/4X
Make X subject of the formula
X= (5/4)/(1/4)
X=5ft.
✓Let us convert 2/3in to feet
If 1/4 in = 1/2 ft
2/3in = x ft
Then cross multiply, we have
1/4×X=2/3×1/2
X=(2/3×1/2)/(1/4)
X=4/3feet
Therefore, the actual dimensions of the kitchen is 5feet by 4/3feet

Step-by-step explanation:
Mary is painting pumpkins to earn money. She plans on selling each pumpkin for $7.50. She currently has $200 in her savings account. Is the amount of money in her bank account proportional to the number of pumpkin she sells?
Answer: No. It's not proportional
Step-by-step explanation:
The direct proportion in mathematics is expressed as:
y = kx
where
y = $200
k = constant
x = $7.50
We then solve for k
y = kx
200 = 7.50k
k = 200/7.50
k = 26.67
Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
A nightclub has approximated the demand for their Thursday night drink special by p^2+200q^2=177, where p is the price (in dollars) and q is the quantity demanded (in thousands). Find and interpret when the price is $ 7 and the demand is 800 drinks.
Answer:
Step-by-step explanation:
Given the approximate demand function of night drink expressed as;
p^2+200q^2=177,
p is the price (in dollars) and;
q is the quantity demanded (in thousands).
Given
p = $7
q = 800
Required
dq/dp
Differentiating the function implicitly with respect to p shown;
2p + 400d dq/dp = 0
400q dq/dp = -2p
200qdq/dp = -p
dq/dp = -p/100q
substitute p and q into the resulting equation;
dq/dp = -7/100(800)
dq/dp = -7/80000
dq/dp = -0.0000875
This means that the rate of change of quantity demanded with respect to the price is -0.0000875

A coach travels to the beach which is 576 KM away in 6 hours. If he is only allowed to travel at a maximum speed of 90 kph, did the coach break the speed limit? What was his average speed?
Answer:
Yes
Step-by-step explanation:
576Km:6Hrs
576 divided by 6=96 km
6 divided by 6=1
96km:1hr
96 was the coaches speed limit
km=Kilometers
Hrs=Hours
96>90
yes , the coach break the speed limit and the average speed is 96 km ph
What is Speed?Speed is the time rate at which an object is moving along a path
Given,
A coach travels to the beach which is 576 KM away in 6 hours.
The maximum speed he can travel is speed of 90 kph
We need to check whether the coach breaks the speed limit or not.
Yes he has to break the speed limit because in 6 hours with 90kph he can travel only 540 km. He still needs to travel 36 km.
and the average speed he has to maintain is 576/6
96kmph
Hence, yes the coach break the speed limit and the average speed is 96 km ph

Each correct answer is worth 134 points, and each incorrect answer is worth −14 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?
Answer:
i. Yes, Nevan won.
ii. Nevan scored 7464 points.
Step-by-step explanation:
Given: each correct answer = 134 points
each incorrect answer = -14 points
Since he got 58 questions correctly, then;
His number of points = 134 x 58
= 7772 points
Also, he got 22 incorrect questions, then;
His number of points = -14 x 22
= -308
Nevan's total points = 7772 + (-308)
= 7772 - 308
= 7464
Nevan scored 7464 points.
Nevan won, and also had a total of 7464 points.
Answer:

Find the value of x.
Answer:
57 degrees
Step-by-step explanation
Answer:
x = 57
Step-by-step explanation:
So we know all triangles add up to 180 degrees. And that supplementary angles add up to 180 degrees.
So, we can do that missing angle + 138 = 180
180 - 138 = 42
180 - 42 - 81 = x = 57

i posted the same question but they didn’t tell me how they got it so could someone show me how they got the answer pleaseee
Answer:
y= -6
Step-by-step explanation:
-4y - 20 + 19 = -y + 17 *add y on the right to get rid of -y
+y +y then add it to -4y
-3y - 20 + 19 = 17 *add 20 to the left to get rid of -20
+20 +20 then add it to 17
-3y + 19 = 37 *subtract 19 from the left to get rid of 19
-19 -19 then subtrcat 19 from 37 as well
-3y = 18 *now we want to divide both sides by -3 to
-3 -3 get y by it's self
y = -6 *no we're left with y = -6 :D
