Answer 1

Answer: 10) 1 gallon of water for every inch of the fish's body length.
a) 2 1/2 inches long fish needs 2 1/2 gallon of water.
b) tank: l = 7 inches ; w = 5 inches; h = 7 ; volume = 7in * 5in * 7in = 245 in³
c) no. her fish tank is not large enough for the fish.
volume of 1 gallon of water is 231 in³, water needed is 2 1/2 gallon, so 5/2 * 231 in³ = 577.50 in³ volume.

11) volume = 7in * 3.5in * 1.75 in = 42.875 in³
weight of the brick = 0.1 pound per cubic inch ⇒ 42.875 in³ * 0.1 lb = 4.2875 pounds
weight of the gold bar = 0.7 pound per cubic inch ⇒ 42.875 in³ * 0.7 lb = 30.0125 pounds

12) l = 55cm ; w = 40cm ; h = 30 cm
volume = 55cm * 40cm * 30cm = 66,000 cm³

$(-2n-2)/(12) = 12$

n=

Answers

$(-2n-2)/(12) = 12 \n \n (-2(n + 1))/(12) = 12 \ / \ factor \ out \ 2 \n \n - (n+1)/(6) = 12 \ / \ simplify \n \n -n - 1 = 12 * 6 \ / \ multiply \ each \ side \ by \ 6 \n \n -n - 1 = 72 \ / \ simplify \n \n -n = 72 + 1 \ / \ add \ 1 \ to \ each \ side \n \n -n = 73 \ / \ simplify \n \n n = -73 \ / \ multiply \ each \ side \ by \ -1 \n \n$

So, your answer to this problem is n = -73.

$(-2n-2)/(12) = 12 \n \n -2n-2 = 12*12 = 144 \n -2n-2 = 144 \n -2n = 144+2 \n -2n = 146 \n n = (146)/(-2) \n n = -73$

Which of the following could represent the scale factor of the smaller figure to the larger figure?4:25
6pi:15pi
8:125
20pi:125pi
16pi:250pi
2:5

Answers

Answer:

It could be 2:5 or 6pi:15pi

Step-by-step explanation:

If you write the ratio of the surface area as a fraction, you would get $(20\pi *yd^(2) )/(125\pi *yd^(2) )$ . Simplifying it would leave $(4)/(25)$ . But this is NOT the answer because that is the ratio of the surface area. You have to square root it to find the scale factor. The square root is $(2)/(5)$ . The answers would be 2:5 and 6pi:15pi.

5a -5=7+2+2a I really need help

Answers

5a-2a=7+2+5
a(5-2)=14
a=14/5-2
a=14/4
a=3.5

Answer:4 2/3

Step-by-step explanation:

5a-5=7+2+2a (combine like terms; 7+2=9)

5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)

3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)

3a=14 (divide both sides by 3; 14/3= 4 2/3)

Ricardo and John start swimming from the same location. Ricardo starts 15 seconds before John and swims at a rate of 3 feet per second. John swims at a rate of 4 feet per second in the same direction as Ricardo. which equation could you solve to find how long it would take John to catch up with Ricardo?A. 4t+3=3t
B. 4t+60=3t
C. 3t+3=4t
D. 3t+45=4t

Answers

speed=distance / time; ⇒distance=speed * time
Distance traveled by Ricardo
Distance (Ricardo)= (3 ft / s) * 15s+3 ft/s * time=45 ft+3 ft/s*t=45+3t

Distance traveled by John:
Distance(John)=(4 ft/s) * time=4t

Distance traveled by Ricardo=Distance traveled by John
3t+45=4t

Answer: D. 3t+45=4t
