Answer:

a =17.08

b = 16.97

Step-by-step explanation:

What are the values of a and b?

Using pythagoras therem';

Hyp^2 = opp^2 + adj^2

Get the value of b;

18^2 = b^2 + 6^2

324 = b^2 + 36

b^2 = 324 - 36

b^2 = 288

b = √288

b = 16.97

Get the value of a;

b^2 + 2^2 = a^2

288 + 4 = a^2

292 = a^2

a^2  = 292

a = √292

a= 17.09

A store owner was buying uniforms for his employees. If each of his stores needed 79 uniforms and he had 64 stores which express
seraphim [82]

Answer:

C)  The total number of  about uniforms needed is  60 x 80 uniforms.

Step-by-step explanation:

The Number of total stores the owner has = 64 stores

The number of employees uniform needed in 1 store  = 79 uniforms

Now, 64 is Rounded off to about 60.

and 79  is Rounded off to about 80.

⇒ The total number of uniforms in 60 stores = 60 x ( uniform in 1 store)

= 60 x  (80 uniforms)  

or, the expression of total uniforms needed = 60 x  (80 uniforms)  

Hence, the total number of  about uniforms needed is 60 x 80 uniforms.

If f(x) = −3x + 4 and g(x) = 2, solve for the value of x for which f(x) = g(x) is true.Noah started to solve the equation –4.6p
barxatty [35]

Answer:

p = 1.2

Step-by-step explanation:

The given equation is :

–4.6p – 6.3p + 3.9 = –9.18

Combining the like terms,

–4.6p – 6.3p = -9.18 - 3.9

−10.9p = −13.08

⇒ p=\dfrac{-13.08}{-10.9}\\\\p=1.2

Hence, the value of p is 1.2
