Mathematics
1 answer:
4vir4ik [10]3 years ago
3 0

Answer:

1.32 * 10^2

Step-by-step explanation:

Given the expression;

(5×10−3)+(6×10−3)2.2×10^4

First we need to do the multiplication first;

= (5×10−3)+(13.2×10−3+4)

= (5×10−3)+(13.2×10^1)

= 0.005 + 132

= 132.005

= 1.32 * 10^2

Hence the equivalent expression is 1.32.0 * 10^2

Sara is 6 feet 3 3/4in tall and Sam is 5 feet 6in. How much taller is Sara then Sam?
denpristay [2]

Answer:

9    3/4  inches

Step-by-step explanation:

If we are finding how much taller Sara is, we need to subtract

6 ft 3 3/4 - 5 ft  6in

I like to line up vertically

  6 ft 3 3/4

- 5 ft  6in

----------------

We  need to borrow 1 ft and make it 12 inches


  5 ft 3+12  3/4

- 5 ft  6in

----------------

   5 ft 15  3/4

- 5 ft  6in

----------------  

  0     9    3/4  inches

How do you solve -5+-3?
Paha777 [63]
- 5 + -3 = -8

hope this helps


when a negative number adds a negative number, it will be negative

when a negative number adds a positive number, whichever number (either positive or negative) take the sign of the bigger one

For example:

-4 + 3 = -1

-5 + 10 = 5

Solve the equation:<br> 4y2 + 7 = 19<br> (write your answer in exact form)
baherus [9]

Answer:

y2=3

Step-by-step explanation:

4y2+7=19

Subtract 7 from both sides.

4y  2 =19−7

Subtract 7 from 19 to get 12.

4y2=12

Divide both sides by 4.

y2= 12/4

Divide 12 by 4 to get 3.

y2=3

One leg of a right triangle is 3 cm and the hypotenuse is 5 cm. Joni found the length of the other leg by evaluating √32 + 52. W
vladimir2022 [97]

Answer: See explanation

Step-by-step explanation:

We should note that the hypothenuse is the longest side in a triangle. Therefore, the length of the other side will be represented by x. This is then solved below:

x² + 3² = 5²

x² + 9 = 25

x² = 25 - 9

x² = 16

x = ✓16

x = 4cm

The other leg is 4cm

Joni shouldn't have added the hypothenuse to the other leg but rather subtracted the square of the other leg from the square of the hypothenuse and then find the square root.
