What is the difference in height between a seagull flying 11 meters above the surface of the ocean and a shark that is swimming 9 meters
below the surface?
a
2 meters
b
-2 meters
20 meters
c
d
-20 meters
Answer:
20 m
Step-by-step explanation:
If the seagull is 11 m above the surface, and the shark is 9 m below the surface, add the 11 m and 9 m to get the absolute value of the distance between the seagull and the shark
11 m + 9 m = 20 m

Cross multiply,

So, these are not in proportion.

c = 27
19)

Two communications companies offer calling plans. With Company X, it costs 30¢ to connect and
then 5e for each minute. With Company Y, it costs 20¢ to connect and then 4¢ for each minute. Write
and simplify an expression that represents how much more Company X charges, in cents, for n
minutes
Which of these expressions represents how much more Company X charges than Company Y?
OA. (30 + 4n) - (20+5n)
OB. 30n -5- 20n - 4
OC. (30n - 4) - (20n-5)
OD. (30 + 5n) - (20 + 4n)
The expression _ represents how much more Company X charges than Company Y.

Find angle 1
(5x+6)° and (7x-18)°
Answer:
Step-by-step explanation:
<1 is the supplement of 5x + 5. You have to assume that the almost horizontal lines are parallel. In addition, two angles on the same side of a transversal across two parallel lines and are interior angles are supplementary.
5x + 6 + 7x - 18 = 180 Add like terms
12x - 12 = 180 Add 12 to both sides
12x = 180 + 12
12x = 192 Divide by 12
x = 192 /12
x = 6
====================
5x + 6 = 5*12 + 6
5x + 6 = 60 + 6
5x + 6 = 66
<1 + 66 = 180
<1 = 180 - 66
<1 = 114

(1/2 + 3/8) x 8 evaluate using order of operation (Pls help it’s due tomorrow)
After simplifying the expression (1 / 2 + 3 / 8) × 8 , we get the result as 7.
We are given the expression:
(1 / 2 + 3 / 8) × 8
We need to evaluate the expression.
For this, we will use the rule of BODMAS.
So, first, we will solve the brackets and add the numbers.
So, we get that:
(1/2 + 3/8) × 8
= ( 4 / 8 + 3 / 8 ) × 8
= ( 7 / 8 ) × 8
Now we will multiply to get the value of the expression:
= 7
Therefore, after simplifying the expression (1 / 2 + 3 / 8) × 8 , we get the result as 7.

The quantity a plus b doubled
The sum of a and b plus 2
Twice the quantity of a and b
The difference of a and b times 2
PLS HELP ASAP
Answer: The quantity a plus b doubled
Twice the quantity of a and b
Step-by-step explanation: You're multiplying the sum of a and b by two. Multiplying by two and doubling is the same. Twice is a synonym for two times. there is no addition happening that involves 2 and there is no subtraction with a and b so the second and fourth choice are eliminated.
Gina has a $50 gift card to a bagel shop. Each Friday, she purchases breakfast for $6. She created a graph to represent the amount of money on her gift card each week. Does Gina's graph represent the situation? Why or why not?
Math item stem image
CLEAR CHECK
Yes, because she starts with $50 on her gift card.
No, because the amount of money on her gift card should decrease each week.
Yes, because the amount of money that she spends increases each week.
No, because the graph should start at the origin.
Answer:
No, because the amount of money on her gift card should decrease each week.
Step-by-step explanation:
Well, the graph shows that the slope is increasing, if you got $50.00 and spend $6.00 each Friday, wouldn't that be decrease and not increase? This is why we eliminate the yes options. Lastly, of course, they should not start at the origin as they started at $50.00.
