A hamster's heart beats about 2,250 beats every 5 minutes. A dog's heart beats about 450 times every 5 minutes.
How many more beats does a hamster's heart beat in 10 minutes than a dog's heart?
Answers
Answer:
4,100
Step-by-step explanation:
add 2,250+2,250=5,000
then add 450+450=900
5000-900+4100
therefore the hamster's heart beats 4,100 more times than a dog in 10 min
if this helped you can i get a thanks or brainliest
2,250 times 2 = 4500
and 450 times 2 = 900
so 4,500-900 is 3600

Step-by-step explanation:
the exponent will tell you how many places u need to move the decimal. 5.7 × 10 to the 2nd power = 570. u moved the decimal 2 places to the right.
If we interpret the statement correctly "5.7 x 5,700,000,000,000" means to multiply 5.7 with 5,700,000,000,000, which gives us the result of 32,490,000,000,000.
Therefore, we can write the statement as: 5.7 x 5,700,000,000,000 = 32,490,000,000,000.

If we are given the equation of a line in this format:
y=mx+b
then it is quite simple to find the gradient and y-intercept.
In the format:
y=mx+b
the m represents the gradient (slope) and b represents the y-interpcept.
1) y=2x+3
gradient= 2
y-intercept= 3
2) y=x-5
gradient= 1
y-intercept= -5
3) y=-2x-4
gradient= -2
y-intercept= -4
4) y=5-x
gradient= -1
y-intercept= 5
5) y=3x+8

Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Part C: Compare the ratio of the areas to the scale factor. Show every step of your work. (4 points)
PLEASE HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
Answer:
6
Step-by-step explanation:
18-2.5+7 there s your helllppppppppppp
New base = 18 x 2/5 = 7.2 feet
New height = 7 x 2/5 = 2.8 feet
Therefore, the dimensions of the new deck are 7.2 feet for the base and 2.8 feet for the height.
Part B: To find the area of the original deck, we can use the formula for the area of a triangle, which is:
Area = (1/2) x base x height
Area = (1/2) x 18 x 7 = 63 square feet
To find the area of the new deck, we can use the same formula and plug in the new dimensions:
Area = (1/2) x 7.2 x 2.8 = 11.88 square feet
Therefore, the area of the original deck is 63 square feet and the area of the new deck is 11.88 square feet.
Part C: The ratio of the areas is:
63/11.88 = 5.303
The scale factor is:
2/5 = 0.4
To compare the ratio of the areas to the scale factor, we can divide the ratio of the areas by the scale factor:
5.303/0.4 = 13.2575
Therefore, the ratio of the areas is 13.2575 times the scale factor.

Step-by-step explanation:
Given:
It takes the sun 2.3 x 10⁸ years to orbit the milky wayIt takes Pluto 2.5 x 10² years to orbit the sunGiven this we want to find :
How many times pluto orbits the sun over the time span that the sun makes one orbit around the milky wayTo get this we must divide the time it takes Pluto to orbit the sun by the amount of time it takes the sun to orbit the milky way
In other words our answer = 2.3 x 10⁸ / 2.5 x 10² = 920000
We can then convert the outputted number into scientific notation
In doing so we get 9.2 x 10⁵
Its important to note that the coefficient (9.2) must have 2 significant figures as the given numbers do.
All we did to convert to scientific notation is add a decimal in between the two sig figs and multiply (9.2) by 10 to the power of how many decimal places we moved over to get to 9.2. Here we moved the decimal point 5 places from 920000. to get to 9.2 therefore the answer in scientific notation would be 9.2 x 10⁵
(You can easily calculate this by plugging this into a calculator)
SUN
2.3 • 10^8= 230000000
PLUTO
2.5 • 10^2 = 250
DIVIDE SUN BY PLUTO
230000000/250 = 920000 Answer

Clare went to a concession stand that sells pretzels for $3.25, drinks for $1.85, and bags of popcorn for $0.99 each. She bought at least one of each item and spent no more than $10.
Could Clare have purchased 2 pretzels, 2 drinks, and 2 bags of popcorn? Explain your reasoning.
Answers
$3.25+$1.85+$0.99= 6.09
$6.09- $10.00= $3.91
Answer: No Clare can't purchased 2 pretzels, 2 drinks, and 2 bags of popcorn
Step-by-step explanation:
Given:
Pretzel = 3.25
Drinks = 1.85
Popcorn = 0.99
No more than $10
To Find:
Could Clare have purchased 2 pretzels, 2 drinks, and 2 bags of popcorn?
Solution:
2 pretzels = 3.25x2
2 Drink = 1.85x2
2 Popcorn = 0.99x2
3.25x2 = 6.5
1.85x2= 3.7
0.99x2= 1.98
Then add all the answer up
6.5+3.7+1.98= 12.18
Therefore, Clare can't purchased 2 pretzels, 2 Drink, and 2 bags of popcorn.
She can buy 2 pretzels, 1 Drink, and 1 bag of popcorn and Cost 9.34 and still have 0.66

A singing competition is auditioning 38 contestants each hour for the next h hours. Which equation can be used to find the total number of contestants, C, that audition in h hours?
Answers
Answer:
C = 38 × (h)
Step-by-step explanation:
If we have 38 contestants per hour, then the number of hours (h) multiplied by 38 people, will tell us the total amount of people who auditioned (C) over h hours.
Total contestants = 38 people for every hour. C = 38h
Answer:
C(h) = (38 contestants/hour)×h
Step-by-step explanation:
Let C(h) = number of contestants audited in h hours. The equation describing this situation is a linear one; in other words, C(h) is directly proportional to h:
C(h) = (38 contestants/hour)×h

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15

\(22k-39=31k+24\)
Rearrange variables to the left side of the equation
\(22k-31k=24+39\)
Combine like terms
\(-9k=24+39\)
Calculate the sum or difference
\(-9k=63\)
Divide both sides of the equation by the coefficient of variable
\(k=-\frac{63}{9}\)
Cross out the common factor
