Answer:
it is B
Step-by-step explanation:
he is putting in by the 3/5
Answer:
C.
Step-by-step explanation:
Why its C...
You can tell that on the top it say that the total is 15 so it can not be a. So now our answer choices are B, C, ad D.
Now it says that there are 3/5 highlighted but since the rest say 3/5 we can not eliminate yet.
Next we would multiply 3 x 3 to get 9 for how many dollars there are. Cross out B.
Between C and D, C is the most reasonable answer because it says how much did he put in the bank while the other one (D) says how much did he spend?
So it would be C

An 8-pound bag of apples costs $6.32. What is the cost per pound
Answer:
$0.79
Step-by-step explanation:
Answer:
$0.79
Step-by-step explanation:
There are two ways to solve this. You can either set it up as a proportion or just divide 8 by $6.32. Be careful if you just divide, however, that you don't divide it the wrong way. 8 divided by 6.32 will give you a different answer than 6.32 divided by 8. Setting up a proportion may be harder and longer, but it is definitely the safer way to go.
Proportion: [tex]\frac{6.32}{8} = \frac{x}{1}[/tex] 6.32 = 8x 6.32 ÷ 8 = 0.79 x = 0.79
79 cents is your answer.

Question 1 (1 point)
Andy bought total of 5 pairs of shoes and soxes. He bought some pairs of shoes and some pairs of soxes.
Set the variabloes as follows:
X = number of pairs of shoes
Y = number of pais of soxes
Which equation shows the total number of shoes and soxes he bought?
2x + 5 y =7
2X + 3 Y = 5
X + Y = 5
7Y - 2x = 5x
Answer:
The equation that shows the total number of shoes and soxes he bought is x+y=5.
Step-by-step explanation:
Given that statement says that Andy bought total of 5 pairs of shoes and soxes this means that the equation would indicate that the sum of the number of pairs of shoes plus the number of pairs of soxes is equal to 5, which can be expressed as:
x+y=5
The other answers are not right because the numbers of pairs of shoes and soxes are multiplied by another number and the statement indicates that the pairs of shoes and soxes is equal to 5.

Find h. 11 in. h = V[?] in. 14 in Enter
Answer:
[tex]h=8.48\ \text{inches}[/tex]
Step-by-step explanation:
Given that,
Radius of cone, r = 7 inches
Slant height of the cone, l = 11 inches
We need to find the height of the cone. Let the height be h. Using trigonometry to find it as follows :
[tex]h^2+r^2=l^2\\\\h=\sqrt{l^2-r^2}\\\\h=\sqrt{11^2-7^2}\\\\h=8.48\ \text{inches}[/tex]
So, the height of the cone is equal to [tex]8.48\ \text{inches}[/tex].

Pythagorean Theorem is a² + b² = c²
Answer:
x = 5.7
Step-by-step explanation:
Formula:
a² + b² = c²
4² + b² = 7²
16 + b² = 49
b² = 49 - 16
b² = 33
[tex]\sqrt{b^2} =\sqrt{33}[/tex]
b = 5.7
I would really appreciate it if someone could answer this I will give a brainlist:)
Answer:
x = 97
Step-by-step explanation:
a^2 + b^2 = c^2
(65^2) + (72^2) = c^2
4,225 + 5,184 = c^2
9,409 = c^2
√9,409 = 97 = c^2
97 = c
97 = x

Charlie is watching hot air balloons. Balloon A has risen at a 60° angle. Balloon B has risen at an 82 angle. If the distance from balloon A to the ground is 1400 feet, how far is balloon B from balloon A? Round your answer to the nearest whole number.
999 feet
1005 feet
1052 feet
1102 feet
Step-by-step explanation:
b is the anwser or 1005 so there u go
the distance between balloon A and balloon B IS 1005 Feet
What is height and distance ?Height is the measurement of an object in the vertical direction and distance is the measurement of an object from a particular point in the horizontal direction.
According to the question,
Angle ADC = 60 degree
Angle BDE = 82 degree
Ac = 1400 Feet
In right angle triangle ACD,
Tan(x)= AC/CD
Tan(60) = 1400/CD
CD = 1400/[tex]\sqrt{3}[/tex]
CD = 808.3
In triangle BDE,
Tan(y) = BE/DE
Tan(82) = 1400/DE { Tan(82) = 7.115 }
DE = 1400/7.115
DE = 196.8
the distance between balloon A and balloon B =CD + DE
= 808.3 + 196.8
= 1005 Feet
Hence, the distance between balloon A and balloon b is 1005 feet

Step-by-step explanation:
The weight of a bass varies jointly as its girth and the square of its length (Girth is the distance around the body of the fish.) A prize-winning bass weighed in at 21.8 lb and
measured 33 in long with a 19-in girth. How much to the nearest tenth of a pound) would a bass 34 in long with a 21-in girth weigh?
The bass would weigh approximately
(Do not round until the final answer. Then round to the nearest tenth as needed.)
The new girth is 22 inches; the reference girth is 20 inches. The weight is proportional to the girth, so the reference weight will get multiplied by 22/20 = 11/10.

Jillian has a circular pool in her backyard with a diameter of 24 feet. What is the circumference of the pool rounded to the nearest tenth of a foot? Use 3.14 for
Answer:
75.36
Step-by-step explanation:
r = radius
pi = 3.14
You know the diameter (2*r) is equal to 24 feet
using the formula for diameter you get 2r = 24
now, you can either solve for r (radius) and plug radius into the formula for circumference OR you can use the 2*r value of 24 feet and plug that into the formula for circumference
if you solved for r directly, you would get r = 12
- then you plug r into the circumerference formula 2*pi*r (where pi 3.14) and you would get 75.36
if you used the diameter value of 2*r, all you would have to do is multiply the given diameter value by pi (3.14) and you would get 75.36
UNIT: feet
NOTE
- you can use the diameter value and simply multiply that by pi because the formula for diameter is 2*r and the formula for circumference is 2*r*pi
