Answer:

x = 5

Step-by-step explanation:

[tex]b = \sqrt{c^{2} - a^{2} }[/tex]

[tex]b = \sqrt{13^{2} - 12^{2} }[/tex]

[tex]b = \sqrt{169 - 144 }[/tex]

[tex]b = \sqrt{25}[/tex]

[tex]b = 5[/tex]

Answer:

Step-by-step explanation:

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.

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.

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.

Answer:

   C. 10.5

Step-by-step explanation:

2=3

3=4.5

4=6.0

5=7.5

6=9

7=10.5

Answer:

the answer is 10.5

Step-by-step explanation:

if you keep going with the relationship every 1 place value up is another 1.5 added so if you go to 7 you get 10.5

Answer:

Its (-2, 0)

Explanation: This is actually very simple because you just simply go left 2 times towards the middle of the two lines crossing each other, and thats -2.  Then after the point doesn't move any farther so its 0.

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

Answer:

x = 48°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°, thus

x = 180° - (90 + 42)° = 180° - 132° = 48°
