four glasses of milk and 2 snack bars have a total of 68 carbohydrates (carbs), and 2 glasses of milk and 3 snack bars have a total of 62 carbs. Determine how many carbs are in one glass of milk and in one snack bar.
Answer: One glass of milk = 10 carbs
Answer: One snack bar = 14 carbs
Step-by-step explanation:
Four glasses of milk and Two snack bars.
4 x 10 = 40
2 x 14 = 28
40 + 28 = 68
Two glasses of milk and Three snack bars.
2 x 10 = 20
3 x 14 = 42
20 + 42 = 62

Wally paid at most Php 350 for the five notebooks and four pad papers that he bought. Suppose each notebook costs Php 42. What could be the greatest price of each pad of paper to the nearest
peso?
Answer:
The each price for pad of paper is 35
Step-by-step explanation:
If one notebook cost 42. Then for 5 notebook
5*42 =210
For pad of paper
350-210
= 140
140÷4
= 35.

The school that Jeremy goes to is selling tickets to a play. On the first day of ticket sales the school sold 8 senior citizen tickets and 9 child tickets for a total of $188. The school took in $70 on the second day by selling 1 senior citizen ticket and 5 child tickets. What is the price of one senior citizen ticket and one child ticket
Answer:
x=$10
y=$12
Step-by-step explanation:
Step one:
given
let senior tickets be x
and child be y
8x+9y=188----1
also on the second day
x+5y=70-------2
the system of equation is
8x+9y=188-----1
x+5y=70---------2
x=70-5y, put this in 1
8(70-5y)+9y=188
560-40y+9y=188
-31y=-372
divide by -31
y=-372/-31
y=$12
put y= 12 in x+5y=70---------2
x+5(12)=70---------2
x+60=70
x=$10

A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 2,417,760,000 times in a year. About how many times faster does the sparrow's heart beat compared to the human heart? Show your work.
Answer: 1577.14
Step-by-step explanation:
From the question, we are informed that a healthy human heart beats about 1,533,000 times a year and that a sparrow's heart beats about 2,417,760,000 times in a year.
To calculate how many times faster the sparrow's heart beat compared to the human heart, we divide the sparrow's heartbeat in a year by the humans heartbeat in a year. This will be:
= 2,417,760,000 / 1,533,000
= 1577.14 times
A T-shirt printing machine takes 80 minutes to print 1120 shirts. Consider the number of shirts printed per minute. Find the constant of proportionality in this situation. b. Write an equation to represent the relationship. How many shirts are printed in 30 minutes?
Answer:
Every minute there are 14 shirts made so there would be 420 shirts made in 30 minutes. Y=14x
Step-by-step explanation:
Divide 1120 by 80 to get 14 then you multiply 14 by 30 to get 420
Then to get an equation you write the number of shirts made per minute and then plug in how many minutes you want.
cuantos lados tiene un polígono regular si su ángulo central mide 24 grados
Answer:
D
Step-by-step explanation:
I’m struggling. Sorry. Any help is appreciated
Answer:
(8x+13)=(10x-27) being vertically opposite triangles.
Now take the 8 to the next side and minus it by 10x which means 10x-8x, the answer is 2x
Then, do with 27 and 13 also and whatever the answer comes it will be divided by 2, so that is the value of x
Answer:
x = 20
Step-by-step explanation:
The 2 angles are vertical and congruent, thus
10x - 27 = 8x + 13 ( subtract 8x from both sides )
2x - 27 = 13 ( add 27 to both sides )
2x = 40 ( divide both sides by 2 )
x = 20
what is the slope of the line
Answer:
-3
Step-by-step explanation:
Slope is rise over run or the change in y over change in x. So to find the slope count the difference from one point to the next, for example (0,4) and (1,1). In this case, the y-value decreases by 3, so -3, and the x-value increases by 1, so +1. Which would be -3/1 or just -3. One way to visually check is to remember that slopes less than -1 or greater than 1 make the line steeper and negative slopes make the graph decrease from left to right.
Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour. Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour. In how many hours will the altitude of moutain climber B be lower than the altitude of moutain climber A?
Answer:
the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.
Step-by-step explanation:
This talks about equalities in math,
We are told about Moutain climber A is at altiude of 250 feet and is descending at a rate of 30 feet per hour, this can be interpreted as
250 - 30h
Moutain climber B is at an altitude of 400 feet and is descending at a rate of 50 feet per hour, this can be interpreted as
400 - 50h
We were now asked how many hours the altitude of mountain climber b be lower than the altitude of mountain climber A, we can interpret this as
(400 - 50h) < (250 - 30h )
We can collect the like terms here
-50h + 30h < 250 - 400
-20h < - 150
The negatives sign can cancelled out, we have
Note that multiplying or dividing by a negative THE INEQUALITY SIGN MUST BE FLIPPED
20h > 150
h > 150/20
h > 7.5
Therefore, the altitude of mountain climber b will be lower than the altitude of mountain climber A with number of hours greater than 7.5hrs.
Using a standard deck of playing cards, what is the probability of drawing a four, replacing the card, and then drawing a club?
A. 1/26
B. 1/51
C. 17/52
D. 1/52
Answer:
D. 1/52
Step-by-step explanation:
There are four 4s in a deck of 52 cards, so there is a 4/52 chance of drawing a four on the first try.
Once you replace the card in the deck, the simulation starts over, meaning the events are independent and you are once again drawing from 52 possible cards.
Now, when you draw the club, the chance of this is 13/52 because there are 13 clubs in a deck.
Because events are independent, multiply the probabilities to determine the chance that both events occur.
[tex]\frac{4}{52} * \frac{13}{52}[/tex] = 1/52
A school raises money by selling 0.5 bags of nuts.
They buy:
-30 pounds of cashews
-15 pounds of almonds
-5 pounds of peanuts
How many 0.5 pound bags can they make?
Answer:
100 bags
Step-by-step explanation:
Answer:
100 bags
Step-by-step explanation:
You're going to want to multiply each amount of pounds the bags are by two. So 30 × 2 is 60. 15 × 2 = 30. 5 × 2 = 10.
60 + 30 = 90
90 + 10 = 100

Solve 1=4|x-2|+2
Help please
Answer:
No solution
Step-by-step explanation:
1=4|x-2|+2
-4|x-2| + 1 = 2
-4|x-2| = 1
False for every value of x
Since absolute value gives only a positive value, the -4 would always make that number negative which doesn't work

what is the solution of −2 < x/4
Answer:
Inequality Form: x > −8
Interval Notation: (−8, ∞)
Step-by-step explanation:
−2 < x/4
Rewrite so x is on the left side of the i nequality.
x/4 > −2
Multiply both sides of the equation by 4.
x > −2 ⋅ 4
Multiply −2 by 4.
x > −8
The result can be shown in multiple forms.
Inequality Form:
x > −8
Interval Notation:
(−8, ∞)

A circle has a diameter of 8 centimeters, as shown below.
8 cm
What is the area, in square centimeters, of the circle?
Answer:
12.6cm²
Step-by-step explanation:
Diameter of circle = 8cm
Unknown:
Area of the circle = ?
Solution:
The area of the circle is given by the expression below;
Area = π r²
r is the radius of the circle
Since diameter is 8cm, radius = 4cm
Insert the parameters;
Area of circle = π x 4cm = 12.6cm²
