Answer:
it is valley
Step-by-step explanation:
it is a valley because the lower numbers in the middle suggest that it gets higher towards the outer layers which means that it goes down in the middle like a hole and a hole is like a valley. :) hope that makes sense
Answer: (a) 4x + 10(0) = 76
(b) 29questions
Step-by-step explanation: let the correct answer = x.
4points for correct answer each total 4xpoints
Since no penalty for wrong answers, his total points were 76points.
Equation: 4x = 76
x = 19. He scored 19 correct answers.
Total number of questions on the test = 19 correct answers + 10 wrong answers
29 questions
Answer:
He can make 3 batches of soup.
Step-by-step explanation:
Starting with 10 pounds of tomatoes and taking out the number of pounds he sets aside for spaghetti sauce, 2.8, we have:
10-2.8 = 7.2 pounds left.
0.2 is read as "two tenths," so 7.2 = 7 2/10
We divide this remaining number of pounds by 2 2/5 for each batch of soup:
7 2/10 ÷ 2 2/5
Convert each to an improper fraction:
72/10 ÷ 12/5
Multiply by the reciprocal:
72/10 × 5/12 = 360/120 = 3
Answer:
The premium is $349 per year
Step-by-step explanation:
We can easily solve this problem by applying a rule of three
$3.49 ---------------------------------------- $1000 coverage
x ---------------------------------------- $100,000 coverage
By using this relation, we can find how much money is needed to pay
x = ($100,000/$1000)*$3.49
x = (100)*$3.49
x = $349
The premium is $349 per year
Answer:
Step-by-step explanation:
<u>Standard form:</u>
<u>Slope intercept form:</u>
<u>Point slope form:</u>
<u>Use the given points and find the slope:</u>
- m = (y₂ - y₁) / (x₂ - x₁)
- m = (1 - 4) / (- 1 - 1) = - 3/ - 2 = 3/2 = 1.5
<u>Point-slope form:</u>
<u>Conv</u><u>ert this to slope-intercept form:</u>
- y - 4 = 1.5(x - 1)
- y = 4 + 1.5(x - 1)
- y = 4 + 1.5x - 1.5
- y = 1.5x + 2.5
<u>Convert this into standard form:</u>
- y = 1.5x + 2.5
- 2y = 3x + 5
- 3x - 2y = - 5
