Answers

Answer:

6.384 rounded to one decimal place is 6.4

Step-by-step explanation:

The number rounded to one decimal place is 6.4.

What is rounding off a number?

To change a number into an approximation having fewer significant digits.

Given that, 6.384 to 1 decimal place,

Rounding 6.384 to one decimal place would be the same as rounding it to the nearest tenth.

The tenth in this number is 3. To round a number up, look at the number to the right of it - if the number is 5 or greater, then you increase the value of the number you're rounding by 1. If the number to the right of it is 4 or less, then the value of the number you're rounding stays the same.

In this case, the number we're rounding is 3 and the number to the right of it is 8. Since 8 is greater than 5, we have to increase the value of 3 by 1, which means that the number in the tenths position is now 4.

Hence, The number rounded to one decimal place is 6.4.

What is the value of x?

Answers

Answer:

98 degrees

Step-by-step explanation:

First, find the value of the other angle of the triangle.

180-53-45 = 82

Then, subtract from 180 to find x. We do this because they both lie on the same line.

180 - 82 = 98

Answer:

5. x = 13

6. x = 11; y = 3

Step-by-step explanation:

5. (9x + 2)° = 119° (alternate interior angles are congruent)

[tex] 9x + 2 = 119 [/tex]

Subtract 2 from each side

[tex] 9x + 2 - 2 = 119 - 2 [/tex]

[tex] 9x = 117 [/tex]

Divide both sides by 9

[tex] \frac{9x}{9} = \frac{117}{9} [/tex]

[tex] x = 13 [/tex]

6. (9x + 25)° = (13x - 19)° (corresponding angles are congruent)

[tex] 9x + 25 = 13x - 19 [/tex]

Collect like terms

[tex] 9x - 13x = - 25 - 19 [/tex]

[tex] -4x = -44 [/tex]

Divide both sides by -4

[tex] \frac{-4x}{-4} = \frac{-44}{-4} [/tex]

[tex] x = 11 [/tex]

(13x - 19)° + (17y + 5)° = 180° (linear pair)

[tex] 13x - 19 + 17y + 5 = 180 [/tex]

Plug in the value of x and solve for y

[tex] 13(11) - 19 + 17y + 5 = 180 [/tex]

[tex] 143 - 19 + 17y + 5 = 180 [/tex]

Collect like terms

[tex] 129 + 17y = 180 [/tex]

Subtract 129 from both sides

[tex] 129 + 17y - 129 = 180 - 129 [/tex]

[tex] 17y = 51 [/tex]

Divide both sides by 17

[tex] \frac{17y}{17} = \frac{51}{17} [/tex]

[tex] y = 3 [/tex]

If m<2=98, m<3=23, and m<8=70 find the measure of each missing angle

Answers

Answer/Step-by-step explanation:

Given:

m<2 = 98,

m<3 = 23,

m<8 = 70

m<1 + m<2 = 180° (linear pair)

m<1 + 98 = 180 (substitution)

m<1 = 180 - 98 (subtracting 98 from each side of the equation)

m<1 = 82°

m<2 + m<3 + m<7 = 180° (sum of angles in a triangle)

121 + m<7 = 180 (substitution)

m<7 = 180 - 121 (subtracting 121 from each side)

m<7 = 59°

m<4 = m<7 (alternate angles are congruent)

Therefore,

m<4 = 59°

m<5 + m<4 + m<3 = 180° (angles on a straight line)

m<5 + 59 + 23 = 180 (substitution)

m<5 + 82 = 180

m<5 = 180 - 82 (subtracting 82 from each side)

m<5 = 98°

m<6 + m<7 + m<8 = 180° (angles on a straight line)

m<6 + 59 + 70 = 180 (subtitution)

m<6 + 129 = 180

m<6 = 180 - 129 (subtracting 129 from each side)

m<6 = 51°

m<9 + m<8 + m<4 = 180° (sum of triangle)

m<9 + 70 + 59 = 180 (substitution)

m<9 + 129 = 180

m<9 = 180 - 129

m<9 = 51°

m<10 + m<9 = 180° (linear pair)

m<10 + 51 = 180° (substitution)

m<10 = 180 - 51

m<10 = 129°

A dinner check is to be split among 3 people. Greg’s portion of the check is twice Kelly’s. Joe’s portion is $1.50 less than 4 times Kelly’s. If the total bill is $114.00, how much does each person owe?

Answers

Answer:

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

Step-by-step explanation:

Let

Kelly's portion = x

Greg's portion = 2x

Joe's portion = 4x - 1.50

Total bill = $114.00

Total bill = Kelly's portion + Greg's portion + Joe's portion

114 = x + 2x + (4x - 1.50)

114 = 3x + 4x - 1.50

114 = 7x - 1.50

Add 1.50 to both sides

114 + 1.50 = 7x - 1.50 + 1.50

115.5 = 7x

Divide both sides by 7

x = 115.5 / 7

= 16.5

x = $16.5

Kelly's portion = x

x = $16.5

Greg's portion = 2x

= 2 × 16.5

= $33

Joe's portion = 4x - 1.50

= 4(16.5) - 1.50

= 66 - 1.50

= $64.5

Therefore,

Kelly owes $16.5

Greg owes $33

Joe owes $64.5

According to the Bureau of Labor Statistics, in a recent year, there were 16,359,000 women aged 25 to 34 who were employed and 5,309,000
who were unemployed but looking for work. What is the rate per 1,000 women aged 25 to 34 who were employed? Round to the nearest whole
number.

Answers

Answer:

The rate of employed per 1000 women is 754

Step-by-step explanation:

Given

Employed = 16,359,000

Unemployed = 5,309,000

Required

Rate per 1000 women of employed

In this case, Rate is calculated by dividing employed by total women

i.e.

[tex]Rate = \frac{Employed}{Employed + Unemployed}[/tex]

[tex]Rate = \frac{16359000}{16359000 + 5309000}[/tex]

[tex]Rate = \frac{16359000}{21668000}[/tex]

Represent the denominator as a factor of 1000

[tex]Rate = \frac{16359000}{21668 * 1000}[/tex]

Divide

[tex]Rate = \frac{754.288086}{1000}[/tex]

Approximate

[tex]Rate = \frac{754}{1000}[/tex]

Hence, the rate of employed per 1000 women is 754

im assuming you meant 2x + y = 6 instead of 2x = y = 6

answer:
x = 14/3
y = -10/3

step by step explanation:
2x + y = 6
x + 2y = -2
solve for y in the first equation
y = 6 - 2x
plug y into the second equation
x + 2(6 - 2x) = -2
-3x + 12 = -2
-3x = -14
x = 14/3
plug into the y equation
y = 6 - 2(14/3)
