Answer:
50 degrees
Step-by-step explanation:
The total sum of angles in a triangle is 180, thus the value of ∠ACB will be obtained as follows:
Given that the triangle is a right triangle, the sum of angles will be:
(4x)°+(7x-20)°+90=180
simplifying and solving for x we get:
4x+7x-20+90=180
11x=180+20-90
11x=110
dividing both sides by 11 we get:
(11x)/11=110/11
this gives us
x=10°
Thus substituting the value of x in:
∠ACB=(7x-20)°
=(7*10-20)
=70-20
=50°
Answer: 50°
A scale drawing of a rectangle park measures 6 inches long and 2 inches wide. If the scale used for the 3 inches equals 7 yards, what is the actual length of the park?
Tara can type 180 words in 4 minutes. At this rate, how many words would you expect her to type in 10 minutes?
Answer:
450 words in 10 minutes
Step-by-step explanation:
To set this up you need to put it like this:
[tex]\frac{180}{4}[/tex] = [tex]\frac{x}{10}[/tex]
From here, you need to cross multiply, which will get you to: 180(10) = 4x
Multiply 180 and 10: 1,800
The equation will now be: 1,800 = 4x
Now, divide both sides by 4: 450 = x
The required word that tara would type in 10 minutes is 450 words.
Given that,
Tara can type 180 words in 4 minutes. At this rate,
To determine how many words would you expect her to type in 10 minutes.
The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
The rate of typing = 180 / 4 = 45 word per minute
Now a number of words typed in 10 minutes,
= 10 * 45
= 450 words per minute,
Thus, the required word that tara would type in 10 minutes is 450 words.

Alba worked for 6 hr and 45 min at $10.90 per hour. What numbers could she use to estimate how much money she earned? Estimate the amount she earned and state whether you think the exact amount is a little more or a little less than your estimate
Answer:
Step-by-step explanation:
If we're going by estimation, then you can do 11 and 7 hours, meaning that she would make 77 for the 7 hours but the exact answer would be a bit less than the estimation
10.9 times 6.75 is 73.58 roughly. so 3 dollars and 42 cents off
Answer:
1. She could use 7 hours and 11 dollars per hour.
2. $77 (7x11)
3 I'd say my estimate is a little more than the exact amount because I did 6.75 (6.75 because 45 minutes is 75% of a hour) x 10.90 and got 73.575.

Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour
Answer:
Mario's unit rate is 5/1
Step-by-step explanation:
We know that Mario walks 5/6 miles per 10 minutes.
We need to find out how many miles Mario walks in 60 minutes (1 hour).
10 * 6 = 60. Which means that we must multiply 5/6 by 6.
[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]
30/6 = 5
Mario walks 5 miles per hour.
To put this in to a unit rate we must put this is a fraction:
[tex]\frac{Miles}{Hour}[/tex]
Substitute:
5/1
Answer:
Mario's unit rate is given by 900 miles/hour
Step-by-step explanation:
We have been given that Mario walked at a rate of 2/3 miles every 10 minutes
We have the relation between speed, time and distance, which is given by
speed = distance/Time
we have,
distance = 2/3 miles
Time = 10 minutes
On substituting these values in above formula, we got
speed 2/3 /10
speed 2/10.3
We have to find the unit rate in mile per hour, so we need to multiply it by 60
Thus, unit rate is given by
1/15 X 60
= 4 miles/hour

PLEASE HELP ITS URGENT
Answer:
x = 48°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°, thus

Answer:
y=-3/5x+2.2
Step-by-step explanation:
Write the equation of the line that passes through the given points. (-2,2.5) and (0,-4.5)
Answer: y = -3.5x - 4.5
suppose: the equation of the line is y = ax + b ( a ≠ 0 )
because the line passes through (-2;2.5) => 2.5 = -2a + b
the line passes though (0;-4.5) => -4.5 = b
=> b = -4.5
2.5 = -2a + b
=> a = -3.5
b = -4.5
=> the equation of the line is y = -3.5x - 4.5
