Kg to Pounds

8.3 kg in ponds is 18.26 lb

Kg to Ounces

8.3 kg in ounces is 292.16 oz

Step-by-step explanation:

We need to convert 8.3 kg to pounds and ounces

The conversion ratio is:

1 lb = 16 oz
1 kg = 2.2 lb

Converting kg to pounds(lb)

We know 1 kg = 2.2 lb

So, 8.3 kg = 8.3*2.2 lb

8.3 kg = 18.26 lb

So, 8.3 kg in ponds is 18.26 lb

Converting kg to ounces (oz)

We know that: 1 lb = 16 oz

We have converted 8.3 kg into 18.26 lb (pounds)

So, 1 lb = 16 oz

18.26 lb = 18.26*16 oz

18.26 lb =292.16 oz(ounces)

So, 8.3 kg in ounces is 292.16 oz

Find the value of c that makes the expression a perfect square trinomial x^2+22x+c with work

Yuliya22 [10]

$\boxed{c=11}$

<h2>Explanation:</h2>

Here we have the following expression:

$x^2+22x+c$

A Perfect Square Trinomial is given by the form:

$(x+a)^2=x^2+2ax+a^2$

So matching terms, we can conclude that:

$2a=22 \\ \\ a=11 \\ \\ c=a^2=121$

So, substituting c into the expression:

$x^2+22x+121$

It is a perfect square because:

$x^2+22x+121=(x+11)^2$

Steve uses an app that shows him how many kilometers he has run to prepare for a marathon. The app said he ran 6.436 kilometers.

8_murik_8 [283]

Steve ran 4 miles.

Step-by-step explanation:

Given,

Distance = 6.436 kilometers

According to given statement;

1 mile = 1.609 kilometers

Therefore,

Distance in miles = $\frac{Distance\ in\ kilometers}{1.609}$

$Distance in miles =\frac{6.436}{1.609}\\Distance = 4\ Miles$

Steve ran 4 miles.

Answer:

a) 67

b) x= -8 and 4

c) 31

Step-by-step explanation:

a) if m<1 = (6x - 5) and m<5 = (5x+7), find m<3.

6x - 5 = 5x + 7

-5x + 5 - 5x + 5

x = 12

6(12) - 5 = 5(12) + 7

72 - 5 = 60 + 7

67 = 67

b) if m<4 = 32 and m<8 = (x^2 - 4x), find x.

32 = x^2 - 4x

- 32 - 32

x^2 - 4x - 32

(x - 8)(x + 4)

x - 8 = 0 x + 4 = 0

+ 8 + 8 - 4 - 4

x = -8 and 4

c) if m<4 = (4x - 17) and m<5 = (5x - 29), find m<1.

4x - 17 = 5x - 29

-5x + 17 -5x + 17

-x = -12

/-1 /-1

x = 12

4(12) - 17 = 5(12) - 29

48 - 17 = 60 - 29

31 = 31
