Answers

Answer 1
(5+4)x2+6-(2x2)-1
5+4 is 9 
mulitpy by 2 to get 18
add 6 to get 24
subtract 4 (2x2) to get 20
then minus 1 
Answer 2

The expression with required parentheses symbols is (5+4)×2+6-(2×2)-1 which has a value of 19.

What is the expression?

Expressions are mathematical statements with a minimum of two terms containing variables or numbers.

We have been the given expression as

⇒ 5+4×2+6-2×2-1

We have to insert parentheses in the given expression so that it has a value of 19.

Here 5+4 = 9

Using parentheses symbols in (5+4) pairs to group

And multiply by 2 to get 18

After adding 6, we get 24

Here subtract (2×2) = 4 to get 20

Using parentheses symbols in (2×2) pairs to group

And then minus 1

⇒ (5+4)×2+6-(2×2)-1 = 19

Therefore, the expression with required parentheses symbols is (5+4)×2+6-(2×2)-1 which has a value of 19.

Is three quarters of earths water salt water?

Answers

The Earth is a watery place. But just how much water exists on, in, and above our planet? About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog.
no, roughly 97% of water on earth is salt water and only 3% is freshwater, since most of the water on earth is from the ocean... btw, this has nothing to do with math... make me the brainliest plz

how wide is a rectangular strip of land with length 6 mi and area 48 square mi? find the perimeter of the rectangular strip of land.

Answers

Final answer:

The width of the rectangular strip of land is 8 miles. The perimeter of the strip is 28 miles.

Explanation:

To find the width of a rectangular strip of land with a length of 6 miles and an area of 48 square miles, we use the formula for the area of a rectangle, which is Area = length × width. Since the area and the length are given, the width can be calculated as Area / length, which is 48 square miles/6 miles = 8 miles wide.

Now, to find the perimeter of the rectangular strip of land, we use the formula Perimeter = 2(length + width). Plugging in the given length of 6 miles and the calculated width of 8 miles, the perimeter equals 2(6 miles + 8 miles) = 2 × 14 miles = 28 miles.

The expression 0.09x+(x−30) models the final price of a bicycle with an instant rebate in a state that charges a sales tax. The tax is on the original price. Which expression represents the amount of tax that is paid on the bicycle?

Answers

The expression "0.09x" represents the amount of tax that is paid on the bicycle.

What is the expression?

Expressions are mathematical statements with a minimum of two terms containing variables or numbers.

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

We have been given that the expression 0.09x + (x - 30) models the final price of a bicycle with an instant rebate in a state that charges a sales tax.

⇒ 0.09x + (x - 30)

Here the tax is on the original price.

Here the tax paid on the bicycle is denoted by the term "0.09x".

Thus, the expression "0.09x" represents the amount of tax that is paid on the bicycle.

Kay scored a total of 35 points in 2 games. she scored 6 times as many in the 2nd game as in the first. how many more points did she score in the 2nd game?

Answers

let the score in the first game be m and in the second be n.
we know that the total score is 35
this means that: m+n=35 .....> equation I
she scored in the second games 6 times as many as in the first one
this means that: n=6m .......> equation II
substitute with equation II in I:
m+6m=35
7m=35
m=5

therefore,
she scored 5 in the first game and 30 in the second one
this means that she scored 30-5=25 points in the second game more than in the first one

Answer:

She scored 25 points in the second game more than in the first one.

in the diagram, ray OT bisects angle SOU, measure of angle UOV equals 35 and measure of angle YOW equals 120 find the measure of each angle

Answers

Final Answers:

m∠ZOY = 60°

m∠ZOW = 180°

m∠VOW = 60°

m∠SOU = 190°

m∠TOU = 95°

m∠ZOT = 85°



Here's a step-by-step solution with the final answers:

1. Identify the given angles:

m∠UOV = 35°

m∠YOW = 120°

OT bisects ∠SOU

2. Find m∠VOW:

∠VOW and ∠YOW are supplementary angles because they form a straight line.

m∠VOW = 180° - m∠YOW = 180° - 120° = 60°

3. Find m∠ZOY:

∠ZOY and ∠VOW are vertical angles, so they are congruent.

m∠ZOY = m∠VOW = 60°

4. Find m∠ZOW:

∠ZOW and ∠YOW are adjacent angles that share a common side (OW).

m∠ZOW = m∠ZOY + m∠YOW = 60° + 120° = 180°

5. Find m∠SOU:

Since OT bisects ∠SOU, m∠TOU = 1/2 * m∠SOU.

We'll find m∠TOU later, so keep this relation in mind.

6. Find m∠TOU:

∠TOU and ∠UOV are adjacent angles that share a common side (OU).

m∠TOU = m∠VOW + m∠UOV = 60° + 35° = 95°

7. Find m∠SOU (using the relation from step 5):

m∠SOU = 2 * m∠TOU = 2 * 95° = 190°

8. Find m∠ZOT:

∠ZOT and ∠TOU are supplementary angles because they form a straight line.

m∠ZOT = 180° - m∠TOU = 180° - 95° = 85°

Final Answers:

m∠ZOY = 60°

m∠ZOW = 180°

m∠VOW = 60°

m∠SOU = 190°

m∠TOU = 95°

m∠ZOT = 85°

find the distance between the points:

(1, 3) and (3, -4)

Please explain and show work

Answers

To calculate distance between two points we use the distance formula sqrt((x2−x1)^2+(y2−y1)^2).  

To start, we find the square of the distance between x1 and x2 and y1 and y2.  The distance between x1 and x2, or 1 and 3, is 2. The distance between y1 and y2, or 3 and -4, is 7.

Now we square 2 and 7 and add them together to get 4 + 49 = 53.

The last thing we do to find the distance is take the square root of 53. 53 is not a perfect square and is also a prime number so our answer in simplest form is still sqrt53.

Mr Diaz decreased the speed of his car by 30 miles per hour over a period of 10 seconds. What is the average change in the speed each second?

Answers

Divide 30 by 10. 30mph/10seconds = 3mph/seconds
Final answer:

By dividing the total change in speed (30 miles per hour) by the total time span (10 seconds), it can be determined that Mr. Diaz decreased his car's speed by an average of 3 miles per hour each second.

Explanation:

In this problem, Mr. Diaz decreased his car's speed by 30 miles per hour over a span of 10 seconds. To find the average change in speed each second, we divide the total change in speed by the total time period.

So, we can calculate the average change as follows:

30 miles per hour ÷ 10 seconds = 3 miles per hour per second

Therefore, the average change in Mr. Diaz's car speed each second is 3 miles per hour.
