Evaluate 20.003+[(30.1+5.75)-6.87

Amanda [17]

Answer:

48.983.

Step-by-step explanation:

(The parentheses are not balanced so I am assuming that there is a square parentheses at the end of the given expression).

Using order of operations (PEMDAS):

20.003 + [(30.1 + 5.75) - 6.87] Work out the inner parentheses first:

= 20.003 + [35.85 - 6.87] Now the outer parentheses:

= 20.003 + 28.98

= 48.983.

Do you know how to do this question

Sever21 [200]

Percentage of the area shaded = 55%

Solution:

Perimeter of the square = 40 cm

Each side of the square = $\frac{40}{4}$ = 10 cm

Area of the square = $\text{side}^2$

= 10²

= 100

Total area of the square = 100 cm²

The unshaded portion is two triangles.

Base of the smaller triangle = 10 cm – 7 cm = 3 cm

Height of the smaller triangle = 10 cm

Area of the smaller triangle = $\frac{1}{2}\times \text{base}\times \text{height}$

$$=\frac{1}{2}\times 3\times 10$

Area of the smaller triangle = 15 cm²

Base of the larger triangle = 10 cm – 4 cm = 6 cm

Height of the larger triangle = 10 cm

Area of the larger triangle = $\frac{1}{2}\times \text{base}\times \text{height}$

$$=\frac{1}{2}\times 6\times 10$

Area of the larger triangle = 30 cm²

Area of the shaded portion = Area of the square – Area of the smaller

triangle – Area of the larger triangle

= 100 cm² – 15 cm² – 30 cm²

Area of the shaded portion = 55 cm²

Percentage of the area shaded = $\frac{\text{Area of the shaded portion}}{\text{Total area of the square}}\times100\%$

$$=\frac{55}{100}\times100\%$

Percentage of the area shaded = 55%

30 treadmills to 36 elliptical machines the ratio in simplest form

Goshia [24]

30 treadmills : 36 ellipticals
this could be written in a few ways, but i am going to write it as a fraction. since treadmills come first, you put 30/36.

now that you have your fraction you have to find the GCF (greatest common factor) of the two numbers. the GCF is 6, so you have to divide 30 treadmills by 6, and 36 ellipticals by 6.
30/6=5
36/6=6

5/6 or 5:6 is the simplified ratio of treadmills to ellipticals

comment for any questions!!
