Parker is in the business of manufacturing phones. He must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. The equation C=175p+400 can be used to determine the total cost, in dollars, of producing pp phones in a given day. What is the y-intercept of the equation and what is its interpretation in the context of the problem?
9514 1404 393
Answer:
400; building and equipment fixed cost
Step-by-step explanation:
The cost equation has two terms. The constant term (400) is the daily fixed cost of building and equipment. The variable term (175p) represents the cost of producing p phones.
The y-intercept is 400. It is the daily fixed cost of the building and equipment.
Answer:
The y-intercept of the function is 400 which represents the fixed cost for rent and equipment.
Step-by-step explanation:
Since Parker must pay $400 even to make 0 phones, that means $400 is the fixed cost that Parker must pay for rent and equipment regardless of the number of phones produced.
Have a good day :)

John is twice as old as Mary. The sum of their ages is 21. How old is Mary?
Let J = John's age and M = Mary's age. Select the system equations that represents the problem.
J - 2M = 0
J = M + 2
M - 2J = 0
J + M = 21
Answer:
Mary is 7
Step-by-step explanation:
If their ages combined equals 21 and john is twice Mary’s age then johns age takes up 2/3 of 21. that would b 14. 14 is 2 x 7. and Mary is 7. 14+7=21. Mary is 7 years old
Correct answers are:
J + M = 21
J - 2M = 0
Kate stands 2 meters from a lamppost. She is 2.1 meters tall and casts a shadow 3 meters long in the light from the lamp. How tall is the lamppost? See diagram below.
Answer:
3.5 meters.
Step-by-step explanation:
Please refer to the attachment.
Since the two triangles share two congruent angles, by AA Similarity, the two triangles are similar.
Therefore, we can write the following proportion:
[tex]\frac{3}{5}=\frac{2.1}{x}[/tex]
To find the height of the lamppost x, we will simply have to solve for x.
So, let’s cross-multiply:
[tex]10.5=3x[/tex]
Divide both sides by 3:
[tex]x=10.5/3=3.5[/tex]
Hence, the height of the lamppost is 3.5 meters.

Trisha uses 3 cups of sugar for every 4 cups of flour to make a batch of cookies. Which equation could be used to solve x, the number of cups of flour needed for 9 cups of sugar.
Answer: The number of cups of flour needed for 9 cups of sugar = 12.
Step-by-step explanation:
Equation of direct proportion between two quantities x and y :
[tex]\dfrac{x_1}{y_1}=\dfrac{x_2}{y_2}[/tex]
Let x= the number of cups of flour needed for 9 cups of sugar.
Put [tex]x_1=4,\ y_1=3,\ y_2=9, x_2=x[/tex]
[tex]\dfrac{4}{3}=\dfrac{x}{9}\\\\\Rightarrow\ x=\dfrac{9\times4}{3}\\\\\Rightarrow\ x=12[/tex]
Hence, the number of cups of flour needed for 9 cups of sugar = 12.
Anna is testing different weights of certain things. The bucket she is holding that is full of water weighs 5lbs. Anna weighs herself and she is 97 pounds. She then drinks all of the water out of the bucket and then weighs herself again. Now she weighs 104 pounds. If the bucket of water she held was only 5 pounds, how did Anna gain 7 pounds from drinking the water out of it?
__________________________________________________
Answer:
Anna drank the water and holding the bucket, which weights 2 pounds, so:
97 + 5 + 2 = 104 poundsAnswer:
104 lbs.Step-by-step explanation:
Anna's self weight = 97
Anna drank the water = 5
bucket weights = 2
total = 104 lbs.
8. Could an angle be complementary to itself? If, so what would it’s measure be?
9. Could an angle be supplementary to itself? If so, what would its measure be?
Answer:
8) angle that is complement of itself is 45°
9) When an angle is its own supplement, that means that the angle, plus itself, will equal 180 degrees.

Answer:
8x +96 yd
Step-by-step explanation:
The perimeter is the sum of the side lengths. In this case, it will be twice the sum of the overall length and the overall height.
The overall length is the sum of the two horizontal segments at top:
(x -2) +(3x) = 4x -2
The overall height is the sum of the right-side vertical segments:
10 + 40 = 50
Then the perimeter is ...
P = 2(L+W) = 2((4x -2) +50) = 2(4x +48) = 8x +96
The perimeter is 8x +96 yards.

Two bags of bird seed are used to fill these three bird feeders. How much bird seed does each feeder use? Represent the situation using the model. Then solve
Step-by-step explanation:
If two bags of bird seed are used to fill these three bird feeders, then we can say that;
2 bags of bird seed = 3 bird feeders
To know the amount of bird seed that each feeder use, we will say;
x bags of bird seed = 1 bird feeder
Equating both postulates and solving
2 bags of bird seed = 3 bird feeders
x bags of bird seed = 1 bird feeder
Cross multiply
3 * x = 2 * 1
3x = 2
subtract 2 from both sides
3x - 2 = 2-2
3x - 2 = 0
Hence model that represents the situation us 3x - 2 = 0 where x is the number of bird seed that each feeder use.
Next is to solve for x;
3x - 2 = 0
3x = 2
x = 2/3
Hence each feeder used 2/3 bird seed

Marissa substracted a negative number from a positive number. Her result was negative. Is that reasonable? Explain.
Answer: It is not reasonable.
Step-by-step explanation: when subtracting a negative number from a positive number the answer is always going to be positive because two negatives make a plus. For example 3-(-5). The two negatives cancel each other out, so it’s 3+5=8
In a full set of permanent teeth, 1/4 of the teeth are incisors, 1/4 are premolars, and 3/8 are molars. What fraction of all the teeth are incisors, premolars, and molars
Answer:
7/8
Step-by-step explanation:
In a full set of permanent teeth, 1/4 of the teeth are incisors, 1/4 are premolars, and 3/8 are molars. What fraction of all the teeth are incisors, premolars, and molars?
To solve the above, we add all the fractions together.
= Incisors + Premolars + Molars
= 3/8 + 1/4 + 1/4
Least Common Denominator = 8
= (3 × 1 + 2× 1 + 2 × 1)/8
= 3 + 2 + 2/8
= 7/8
Hence, the fraction of all the teeth are incisors, premolars, and molars is 7/8
2 1/2 + 3 5/8
Add the fractions

Answer:
6 1/8
2 1/2 becomes 5/2 then you multiply the numerator and denominator by 4

Step-by-step explanation:
Martha compra 2 kilos de tomate y 1 kilo de cebolla pagando S/ 8,40. Si la siguiente semana compra 1 kilo de tomate y 2 kilos de cebolla pagando S/ 7,80, ¿a cuánto está el kilo de cebolla?
Responder:
2,40
Explicación paso a paso:
Dado que:
Dejar :
Tomate = t
Cebolla = n
(2 kilo de t) + (1 kilo de n) = 8.40
(1 kilo de t) + (2 kilo de n) = 7.80
2t + n = 8,40 - - (1)
t + 2n = 7,80 - - (2)
De (2);
t = 7,80 - 2n
Ponga t = 7.80 - 2n en (1)
2 (7,80 - 2n) + n = 8,40
15,6 - 4n + n = 8,40
15,6 - 3n = 8,40
-3n = 8,40 - 15,6
-3n = - 7,2
n = 2,4
t = 7,80 - 2 (2,40)
t = 7,80 - 4,80
t = 3
Por lo tanto, el costo de 1 kilo de cebolla es 2,40
