Step-by-step explanation:

\underline{ \underline{ \text{Given}}} :

  • Hypotenuse ( h ) = 15
  • Perpendicular ( p ) = a
  • Base ( b ) = 9

\underline{ \underline{ \text{To \: find}}} :

  • Value of a

\underline{ \underline{ \text{Solution}}} :

\underline{ \text{USE \: PYTHAGOREAN \: THEOREM}} :

⤏ \tt{ {p}^{2}  =  {h}^{2}  -  {b}^{2} }

⤏ \tt{ {a}^{2}  =  {15}^{2}  -  {9}^{2} }

⤏ \tt{ {a}^{2}  = 225 - 81}

⤏ \tt{ {a}^{2}  = 144}

⤏ \tt{a =  \sqrt{144}}

⤏ \tt{a =  \sqrt{ {(12)}^{2} } }

⤏ \tt{a = 12}

\red{ \boxed{ \boxed{ \text{Our \: final \: answer :  \boxed{ \tt{12 \:  \text{units}}}}}}}

Hope I helped ! ツ

Have a wonderful day / night ! ♡

What is 155.78=2.95h+73.18<br> a. 28<br> b. 36<br> c. 3.6<br> d. none of these
xz_007 [3.2K]

Answer:

a. 28

Step-by-step explanation:

Given:

155.78=2.95h+73.18

We need to evaluate given expression to find the value of 'h'.

Solution:

155.78=2.95h+73.18

Now first we will apply Subtraction property of equality and subtract both side by 73.18 we get;

155.78-73.18=2.95h+73.18-73.18\\\\82.6=2.95h

Now we will use Division property of equality and divide both side by 2.95 we get;

\frac{82.6}{2.95}=\frac{2.95h}{2.95}\\\\h=28

Hence After evaluating given expression we get the value of 'h' as 28.

28/29 and 30 plz short explanation thanks
iren2701 [21]

Integers are numbers like ...-3, -2, -1, 0, 1, 2, 3... and so on. So, according to this definition, let's solve this problem:


28. We know that the product of three integers is -3. So, the statement states that we have three factor, so:


a.b.c = -3


The possible values of the factors are:

  • Factors are: 3, 1 and -1 in which case:

(3)(1)(-1) = -3

  • Factors are: -3, 1 and 1 in which case:

(-3)(1)(1) = -3


29. In this problem we know two nonzero integers, that is, they cannot be equal to zero. Thus, they must have different sign, that is, one of them must be positive and the other negative. For instance:


  • -9 and 2

(-9)(2) = -18, So -18 is less than -9 and 2


Another example:


  • 1 and -8

(1)(-8) = -8, So -8 is equal to -8 and -8 is less than 1.


30. The sign of the product of two integers with the same sign is positive, that is:


(+)(+) = (+) and

(-)(-) = (+)


So, the sign of the product of three integers with the same sign are two options:

  • <u>Option 1.</u> The three integers are positive in which case:

(+)(+)(+) = (+), So the sign of the product is positive


  • <u>Option 2.</u> The three integers are negative in which case:

(-)(-)(-) = (-), So the sign of the product is negative.


This option two gives us that result because:


(-)(-) = (+) and (+)(-) = (-)

An integer is 8 more than 5 times another. If the product of the two integers is 36, then find the integers
Harman [31]

Answer:

see below

Step-by-step explanation:

1st:  x

2nd:  5x + 8

x(5x + 8) = 36

5x² + 8x = 36

5x² + 8x - 36 = 0

(x - 2)(5x + 18) = 0

(x - 2) = 0

x - 2 = 0

x = 2

1st:  x = 2

2nd:  5x + 8 = 5(2) + 8 = 18

(5x + 18) = 0

5x + 18 = 0

5x = -18

x = -3.6

1st:  x = -3.6

2nd:  5x + 8 = 5(-3.6) + 8 = -18 + 8 = -10
