Answer:

70kg

Step-by-step explanation:

30% of 100kg is

--> 100 x 30/100 which is 30kg.

If you want to decrease 100kg by 30%, you can take away 30kg from 100kg.

--> 100 - 30 = 70

So 70kg is the remainder.

How do i solve divide 5/8 by 50%

Ede4ka [16]

50% is $\frac{50}{100}$
We have two ways to do this, pick your favor:
either by fractions:
$\frac{5}{8}$ ÷ $\frac{1}{2}$
( $\frac{50}{100} = \frac{1}{2}$
Multiply by the reciprocal of $\frac{1}{2}$ which is 2(flip it)

$\frac{5}{8}$ × 2 = $\frac{5}{4}$ = 1.25

Or change them to decimals:
$\frac{5}{8} = 0.625$
$\frac{50}{100}$ = 0.5

0.625 ÷ 0.5

0.5 I 0.625
multiply by 10 to make it easier to divide(it still gives us the same answer)
0.5 × 10 = 5
0.625 × 10 = 6.25
1.25
5 I 6.25
-5
12
-10
25
-25
0

0.625 ÷ 0.5 = 1.25

Please answer this question, 30 points and will give brainliest!

Answer:

∠C = 80 ° ; ∠ T = 40°.

Step-by-step explanation:

Triangle CRS is isosceles because it has two sides of equal length. (CR and CS are radii).

An isosceles triangle has also two equal angles, which means that ∠CRS= ∠CSR.

Therefore, ∠C = 80 ° (180° – 50° - 50°) because the sum of angles in a triangle is 180 degrees.

∠C is the central angle of the arc RS.

∠ T is the inscribed angle of the arc RS.

An inscribed angle is half of a central angle that subtends the same arc on the circle, so the inscribed angle ∠ T is half of the central angle ∠C. Since ∠C = 80 °, we can easily determine the measure of ∠ T:

80° divided by 2 is 40°.

Which is the graph of the linear inequality 1/2 x-2y>-6 ?

larisa86 [58]

Answer:

<h2>Your Answer is C!!!!!!!!!</h2>

Steps:

$\frac{1}{2} x-2y>-6$

Add 2y to both sides:

$\frac{1}{2} x-2y+2y>-6+2y$

Simplify:

$\frac{1}{2}x>-6+2y$

Multiply both sides by 2:

2· $\frac{1}{2}x>-2$ ·6+2·2y

Simplify:

x>-12+4y
