S_A_V [24]3 years ago
3 0

Answer:

√19 or 4.36

Step-by-step explanation:

Since one leg is missing, you need to use Pythagorean theorem for this.

The hypotenuse is known so,

c² - a² = b²

c = 10

a = 9

b = ?

10² - 9² = b²

100 - 81 = b²

19 = b²

b = √19

I have four questions please answer all! With data/evidence
SOVA2 [1]
To answer all these questions you will use the formula A= bh. In words this means to find the area you multiply the base times the height. For each of these examples, you are given the area and you have to find the missing dimension. Each of these will be set up as four separate equations that need solved. Here they are 0.225=0.6h, 4.86=1.8b, 63=12b, and 2.5=5h. To solve all four of these and show evidence, you were divided the area by the dimension that you know. 0.225÷0.6, 4.86÷1.8, 63÷12, and 2.5÷5. With any multiplication equation if you know the total, you have to divide to find the missing part. The answers for each of these in order that they are presented our 3.75 miles, 2.7 yards, 5.25 m, and 0.5 km. None of the answers are square units because they are only giving a one dimensional measurement.

triumphant college is planning to increase the registration fee by 11.5%.if the registration fee is currently N$ 1000, how much
frozen [14]

Current registration fee at triumphant college = N$ 1000

Percentage by which the registration fee will be increased next year = 11.5%

Registration fee at triumphant college next year :

= Current registration fee + 11.5% of current registration fee

=\tt1000 +  \frac{115}{10 \times 100}  \:  \: of \:  \: 1000

= \tt1000 +  \frac{115}{1000}  \times 1000

=\tt 1000 +  \frac{115000}{1000}

=\tt 1000 + 115

\color{plum} = \tt \:\bold{ N\$ \: 1115}

Therefore, the registration fee at triumphant college next year = <u>N$ 1115</u>

Triangle sum (3x+1)^0+(10x-11)^0+(3x-2)^0=180
svetlana [45]

Answer:

  • x = 12
  • 3x+1 = 37°
  • 10x-11 = 109°
  • 3x-2 = 34°

Step-by-step explanation:

Perhaps you want to know the value of x or the measures of the angles?

__

Simplifying the given equation, you get ...

  (16x -12)° = 180°

  16x = 192 . . . . . . . divide by °, add 12

  x = 12

  (3x+1)° = (3·12+1)° = 37°

  (10x-11)° = (10·12-11)° = 109°

  (3x-2)° = (3·12-2)° = 34°

x is 12, and the angle measures are 37°, 109°, 34°.
