Lin's job pays $8.25 an hour plus $10 of transportation allowance each week. She has to work at least 5 hours a week to keep the job, and can earn up to $175 per week (including the allowance). Represent this situation mathematically in two inequalities. Let `x` represent the number of hours Lin works in a week. Inequality 1:
Answers
Answer:
Kindly check explanation
Step-by-step explanation:
x = number of hours Lin works in a week
Inequality (1) : Least Numbe rod hours worked
x ≥ 5 - - - (1)
Possible earning including transportation allowance :
8.25x + 10 ≥ 175 - - - (2)
Solving for X from (2)
8.25x ≥ 175 - 10
8.25x ≥ 165
x ≥ 20 hours
To earn upto 175 per week, then he has to work for 20 hours

Round 1.5 to one decimal place
Answers
Answer:
2
Step-by-step explanation:
Since rounding to the one place relies on the decimal part, the part to focus on is the .5
becuase anything greater or equal to 5 is rounded up, the answer is 2
1.5 rounded to one decimal place will be 2.
What are Places' values?Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
Given a fraction number 1.5 that needed to be rounded to one decimal place. Since it's at the equidistance from the nearest whole number then we will follow the even number rule.
Rounds towards the nearest neighbor, but if equidistant, it rounds towards the even number. Both 1.5 and 2.5 are rounded to 2
therefore, 1.5 will be 2, when rounded to the nearest tenth.

The measure of L in triangle LMN is 32°. The measure of M is 69°. What is the measure of N?
A.
79°
B.
259°
C.
101°
D.
37°
Answers
Answer:
A) 79
Step-by-step explanation:
m<N = x
All angles in a triangle add up to 180 so:
x + m<L + m<M = 180
x + 32 + 69 = 180
x + 101 = 180
x = 180 - 101
x = 79
Answer:
It is (A) 79°
The summation of the triangle's angles are 180°
Step-by-step explanation:
[tex]m + l + n = 180 \\ 69 + 32 + n = 180 \\ n = 180 - 101 \\ n = 79 ^{ {} ^{.} } [/tex]
How much of a radioactive kind of niobium will be left after 105 days if you start with 3,920 grams and the half-life is 35 days?
Answers
Answer:
"490 grams" would be the correct solution.
Step-by-step explanation:
The given values are:
Half time,
T = 35 days
Total time,
t = 105 days
As we know,
⇒ [tex]A=A_o(\frac{1}{2} )^{\frac{t}{T} }[/tex]
On substituting the values, we get
⇒ [tex]=3920\times (\frac{1}{2})^{\frac{105}{35} }[/tex]
⇒ [tex]=3920\times (0.5)^3[/tex]
⇒ [tex]=3920\times 0.125[/tex]
⇒ [tex]=490 \ grams[/tex]

Kerel wants to buy a Points card for his X-box live account. He can buy a 200-point
card for $10.00 or a 300-point card for $15.00. Which card is the better value?
Answers
Answer:
equal. i think
Step-by-step explanation:
well if 10$ is worth 200 and 15 is worth 300 for me its adding half of the orginal number (200) and get 100 so 200+100=300
Both the cards are having the same value
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the first card be = A
Let the second card be = B
Now ,
The value of first card = $ 10.00
The value of second card = $ 20.00
And ,
The total value for 200 point cards = value of first card
The total value for 300 point cards = value of second card
So , the equation will be
200 = 10 A be equation (1)
300 = 15 B be equation (2)
Divide equation (1) by 10 on both sides , we get
A = 20
Divide equation (2) by 15 on both sides , we get
B = 20
Therefore , A = B
Hence , Both the cards are having the same value

This is a scale drawing of a flag. The scale factor of a drawing to the actual flag is represented by the ratio 1:18. What is the area, in
square inches, of the actual flag?
Answers
Answer:
648 sq. in.
Step-by-step explanation:
The ratio of the flag is 1:18 and the question asks for the area of the flag.
To find the actual flag size, you got to multiply the width by 18.
Then you must multiply the length by 18.
A= LxW
A=36 x 18
A= 648 sq. in.
Therefore, the area of the actual flag is 648 sq. in.
