Answer:
75 miles
Step-by-step explanation:
If the bird flies for 90 minutes at 50 mph (miles per hour), we need to calculate how many hours 90 minutes is.
One hour is 60 minutes. Our equation will be: 90/60 = 1.5
This mean the bird flies 1.5 hours at 50 mph. To find the distance, we multiply 1.5 by 50.
1.5 × 50 = 75
The bird has flown 75 miles.

PLEASE HELP ME
I will make you brainliest.
Given,
[tex] - 98 = - 7h[/tex]
[tex] \implies \: - 7h \: = - 98[/tex]
[ Firstly, Arrange it ]
Now,
[tex] \implies \: h = \cancel\dfrac{ - 98}{ - 7} [/tex]

9. Combine the radical expression, if possible.
Answer:
we conclude that:
[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]
Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.
Step-by-step explanation:
Given the expression
[tex]3\sqrt{125}+4\sqrt{20}[/tex]
Combining the radical expressions
[tex]3\sqrt{125}+4\sqrt{20}[/tex]
let us first solve
[tex]3\sqrt{125}[/tex]
[tex]=3\sqrt{5^3}[/tex]
[tex]=3\sqrt{5^2\cdot \:5}[/tex]
Apply radical rule: [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]
[tex]=3\sqrt{5^2}\sqrt{5}[/tex]
Apply radical rule: [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]
[tex]=3\cdot \:5\sqrt{5}[/tex]
[tex]=15\sqrt{5}[/tex]
Thus,
[tex]3\sqrt{125}=15\sqrt{5}[/tex]
similarly solving
[tex]4\sqrt{20}[/tex]
[tex]=4\sqrt{2^2\cdot \:5}[/tex]
Apply radical rule: [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]
[tex]=4\sqrt{2^2}\sqrt{5}[/tex]
Apply radical rule: [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]
[tex]=4\cdot \:2\sqrt{5}[/tex]
[tex]=8\sqrt{5}[/tex]
Thus,
[tex]4\sqrt{20}=8\sqrt{5}[/tex]
so we get
[tex]3\sqrt{125}=15\sqrt{5}[/tex]
[tex]4\sqrt{20}=8\sqrt{5}[/tex]
so the expression becomes
[tex]3\sqrt{125}+4\sqrt{20}=15\sqrt{5}+8\sqrt{5}[/tex] ∵ [tex]3\sqrt{125}=15\sqrt{5}[/tex] , [tex]4\sqrt{20}=8\sqrt{5}[/tex]
[tex]=23\sqrt{5}[/tex] ∵ [tex]15\sqrt{5}+8\sqrt{5}=23\sqrt{5}[/tex]
Therefore, we conclude that:
[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]
Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.

What is the volume of a spherical water balloon with a radius of 6 inches?
Answer:
288πin³
Step-by-step explanation:
Volume of a sphere is expressed as;
V = 4/3πr³
r is the radius = 6 inches
Substitute into the formula
V = 4/3π(6)³
V = 4/3π(216)
V= 864/3π
V = 288π in³
Hence the volume of the sphere is 288πin³

The length of the rectangle shown below is represented by the expression (x - 2)2. The width is represented by the expression (3x - 5). What is the area of the rectangle?
Answer:
(6x² - 22x + 20) square units
Step-by-step explanation:
The area of a rectangle is calculated as:
Length × Width
From the question
Length = (x - 2)2 = 2x - 4
Widths = 3x - 5
The area of the rectangle =
(2x - 4 ) × (3x - 5)
2x(3x - 5) -4(3x - 5)
6x² - 10x - 12x + 20
6x² - 22x + 20
The area of the rectangle =
(6x² - 22x + 20) square units

(please help!)Abigail invested $2,900 in an account paying an interest rate of 2.8% compounded
quarterly. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $4,050?
Answer:
Step-by-step explanation:
4050 = 2900 (1 + 0.028/4)^4t
4050 = 2900 (1.007)^4t
Divide all by 2900
1.3965517 = 1.007^4t
TURN LOG
log (1.3965517) = log (1.007^4t)
47.8819724 = 4t
11.9704931 = t
Round to nearest year = 12
T = 12

On a map with a scale of 1 inch= 100 miles, the distance between two cities is 7.55 inches. If a car travels 55 miles per hour, about how long will it take to get from one city to another.
Answer:
13.73 hours
Step-by-step explanation:
On a map with a scale of
1 inch= 100 miles
the distance between two cities is 7.55 inches.
We convert from inches to miles
1 inch = 100 miles
7.55 inches = x
x = 7.55 × 100 miles
x = 755 miles
The distance between the two cities = 755 miles
If a car travels 55 miles per hour, about how long will it take to get from one city to another?
We are to calculate the Time
Speed = Distance /Time
Time = Distance/Speed
Hence, the time is calculated as:
755 miles/55 miles per hour
= 13.727272727 hours
≈ 13.73 hours
