Solve for h .
-98 = -7 h
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]
minus sign minus sign are also canceled.
[tex] \implies \: h \: = 14[/tex]
hence,the value of h is 14 .
(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

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

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

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.
