Answer the following questions using metric conversions.
13. One pack of Strawberry Poptarts has a mass of 104 g. What is the mass of 6 packs of Poptarts? How many kg is 6 packs of Poptarts? Explain your answer.
14. Will a tablecloth that is 155 cm long cover a table that is 1.6 m long? Explain.
15. Alex rode 2 kilometers on his bike. His sister rode 3000 meters on her bike. Who rode
the farthest and how much farther did they ride? (Answer in meters)
Answer:
Ok, here is the answers! brainliest pleaseee :D
Step-by-step explanation:
13. - 0.624 kg. (Explanation: 104 grams per one pack of pop-tarts. 104 g x 6 packs of pop-tarts equal 624 grams in total. 624 grams to kilograms is 0.624 kg.)
14. - No. The tablecloth is 155 cm long. It needs to cover a table that is 1.6 meters long. 155 cm to meters is 1.55 meters. The tablecloth is 0.05 to short to cover the table. 1.6 meters - 1.55 meters = 0.005.
15 - Alex's sister rode the farthest. She rode 1,000 meters farther than Alex. 2 kilometers in meters is 2,000 meters. His sister rode 1,000 meters more than that, 3,000.

Tom is building a new barn for all of his farm equipment.
He spend $35,000 in buying raw materials and $40,000 in labor and machinery to build the barn.
This total amount came out to be 20% less than what he had budgeted for the barn.
What was the amount he had budgeted for the barn?
Answer: $
Answer:
Build the barn : $35,000 + $40,000 = $75,000
Budgeted for the barn : $75,000 x 80% = $60,000

Step-by-step explanation:
Find equation of the line shown
Answer:
y = x + 6
Step-by-step explanation:
y = mx + b
Since (0,6) is your y-intercept (or just positive 6), you have your b part of the equation solved.
The line goes up at a continuous rate of up 1, over 1, so they cancel each other out, making the m part of your equation 1.
So, you have y = 1x + 6 and you change it to just y = x + 6 (since x itself automatically has a 1 before it, when it's by itself).
Hope this helps!
write the point-slope equation of the line that passes through(3,5) and (7,1)
Answer: y - 1 = –(x –7)
or y –5 = –1(x –3)
The attachment shows the graph of these equations (identical)
Step-by-step explanation:
The basic form for a point-slope equation is
y - b = m(x - a)
a is the x-value from the given coordinate, b is the y-value form the given coordinate, m is the slope. x and y are the variables in the function.
To find the slope, m, use the given coordinates. Get the difference in the y-values and divide by the difference in the x-values. This is "rise over run."
Subtract the first coordinate from the second coordinate.
Given coordinate points: (3,5) and (7,1) substitute values:
m= 1 –5 / 7 –3 becomes m= –4/4 so the slope, m = –4/4
That is –1 The "1" is "understood," so only the negative sign represents the slope in the equation
To write the equation: Take the basic form, substitute b and a values from either given coordinate. And use the value of m we just calculated.
y - b = m(x - a) Using the second coordinate: (7,1)
y - 1 = –(x –7)
or using the first coordinate:
y –5 = –(x –3)
Find the slope of the line that passes through (73, 73) and (7, -10).
Answer:
M= 83/66
Step-by-step explanation:
The formula to solve the slope is y2-y1/x2-x1 so ,
-10-73= -83
7-73= -66
-83/-66= 83/66

6 x 10^9 divide 3x10^4 = ____x10^?
Answer:
2 × 10⁵
Step-by-step explanation:
The following data were obtained from the question:
6×10⁹/ 3×10⁴ =?
The above expression can be simplified as follow:
6×10⁹/ 3×10⁴ = 6×10⁹ ÷ 3×10⁴
Recall:
Aᵐ ÷ Aⁿ = Aᵐ ¯ ⁿ
Therefore,
6×10⁹ ÷ 3×10⁴ = (6/3) × 10⁹ ¯ ⁴
6×10⁹ ÷ 3×10⁴ = 2 × 10⁵
Thus, 6×10⁹/ 3×10⁴ is equal to 2 × 10⁵
Alex has 3,330 toothpicks . He wants to use them all to make a floor mat with 18 equal rows . How many toothpicks should Alex use for each row ?
Answer:
Step-by-step explanation:
for this problem we have to
3330/18=185 toothpicks for each row
Answer:
185
Step-by-step explanation:
Divide 3330 by 18.
3330 is the number of tooth pics he has, so divide by how many rows he needs, 18.

Carlos has $50 in his saving account. he deposits $100 on his birthday. Every month after his birthday, he deposits $25. which equation can be used to calculate the number of months it will take him to have $500?
Answer:
im not sure sorry..
Step-by-step explanation:
Answer:
so don't know the equation but it's 15 months. a year and 3 months.
Step-by-step explanation:
so first able, he already has 150 in his saving account. he adds 25$ every month after hai bday. a year has 12 months in which one of them is his birthday. so the rest 11 months he adds 25$. 25×11=275 then 150+275=425 so he needs 75 more dollars to have 500$ 25+25+25=75 so there fore we have 3 more months. so that means that a year and three months. sorry if you didn't understand I'm bad at explaining

x + y = 10
y = ?
solution: (7, y)
Answer:
y=3
Step-by-step explanation:
Given: x+y=10
solution is (7,y)
put x=7 in x+y=10
⇒7+y=10
⇒y=10-7
⇒y=3
Hence, the value of y is 7.

Find VX.
A. 3.0
B. 2.6
C. 6.1
D. 4.6
Answer:
B
Step-by-step explanation:
You have given angle x and the hypotenuse you are asked to find the adjacent side of the triangle so you would be using
Cosθ = Adjacent/hypotenuse.
cos49 = adjacent/4
1.32 = adjacent/4
2.62 = adjacent
VX = 2.6
Remember!
SOH
Sinθ = opposite/hypotenuse
CAH
Cosθ = adjacent/hypotenuse
TOA
Tanθ = opposite/adjacent

Can someone please give me this answer.
Answer:32 inches
Step-by-step explanation:
Using the pythagorean theorem
40²= 24²+ b²
simplify

What is 360 in the ratio 1 : 8
Answer:
40 : 320
Step-by-step explanation:
sum the parts of the ratio, 1 + 8 = 9 parts
Divide the quantity by 9 to find the value of one part of the ratio
360 ÷ 9 = 40 ← value of 1 part of the ratio, then
8 parts = 8 × 40 = 320
Then 360 in the ratio 1 : 8 is 40 : 320
Answer:
40:320
Step-by-step explanation:
8+1=9
360/9=40
40 times 1 is 40
40 times 8 is 320
