Answer:
24 is the answer
Step-by-step explanation:
2a + 5 = 53
-5 -5
0 48
2a/2= a
48/2= 24
THEREFORE a=24

Jessica wants to spend less than $50.00 per month on her cell phone bill. Write an inequality that shows how many text messages Jessica must limit herself to in order to keep her monthly bill less than $50.00. Use the symbol for your inequality.
Missing part of question:
Jessica pays a flat rate of $20 for her cell phone and is charged $0.05 for every text she sends.
Answer:
20.00 + 0.05x < 50.00
Step-by-step explanation:
Given
Base Amount = $20
Rate = $0.05 per text
Budget = Less than $50.00
Required
Write an inequality that represents the scenario
Let x represents the number of texts
To solve this, the base amount when added to the amount paid for x text must be LESS THAN Jessica's budget.
Mathematically, we have:
Base Amount + Rate * x < Budget
Substitute values for Base Amount, Rate and Budget, this gives:.
20.00 + 0.05 * x < 50.00
20.00 + 0.05x < 50.00
Hence, the inequality that represents the scenario is 20.00 + 0.05x < 50.00
Solving further for x, we have:
20.00 + 0.05x < 50.00
Collect Like Terms
0.05x < 50.00 - 20.00
0.05x < 30.00
Solve for x
x < 30.00/0.05
x < 600
This means that she must send less than 600 text messages.

Use the change of base rule to find the logarithm to four decimal places. (2 points) log base nine of 0.877.
Given:
The value is [tex]\log_90.877[/tex].
To find:
The logarithm to four decimal places using the change of base rule.
Solution:
We have,
[tex]\log_90.877[/tex]
Using the change of base rule, we get
[tex]\log_90.877=\dfrac{\log_{10}0.877}{\log_{10}9}[/tex] [tex][\because \log_yx=\dfrac{\log_ax}{\log_ay}][/tex]
[tex]\log_90.877=\dfrac{-0.057000}{0.9542425}[/tex]
[tex]\log_90.877=-0.0597332439081[/tex]
Round the value to the four decimal places.
[tex]\log_90.877\approx -0.0597[/tex]
Therefore, the required value is -0.0597.

Solve for w.
5w/8 = 15
solve step by step with a good explanation.
if you get this correct and solve step by step then i will mark you brainliest!
Answer:
w = 24
Step-by-step explanation:
[tex]\frac{5w}{8}[/tex] = 15
Multiply both sides by 8.
5w = 15 × 8
= 120
Find w.
w = 120 ÷ 5
w = 24
The angle of elevation of top of a tower from a point on the ground, which is 30 m away from the foot of the tower is 30°. The length of the tower is a.√3 m b.2√3 m c.5√3m d.10√3 m
Answer: d
Step-by-step explanation:
Note that the distance to the tower and the height of the tower create a right triangle at the base of the tower. The equation to find the height of a right triangle is to multiply the length times the tangent of angle β.
Given:
b = a · tanβ
tan(30°) = √3/3
Step 1: Solve
b = (30/1) · (√3/3)
b = (30 · √3) / (1 · 3)
b = (30√3) / (3)
b = 10√3

A gardener is planting two types of trees: Type A is 10 feet tall and grows at a rate of 19 inches per year. Type B is 4 feet tall and grows at a rate of 25 inches per year. Algebraically determine exactly how many years it will take for these trees to be the same height.
Answer:
It'll take 12 years
Step-by-step explanation:
Given
Type A:
[tex]Initial\ Height = 10ft[/tex]
[tex]Growth = 19in[/tex]
Type B:
[tex]Initial\ Height = 4ft[/tex]
[tex]Growth = 25in[/tex]
Required
Determine the years they'll reach the same height
First, convert feet to inches in both measurements (this is done by multiplying measurement by 12):
Type A:
[tex]Initial\ Height = 10ft[/tex]
[tex]Initial\ Height = 10 * 12in[/tex]
[tex]Initial\ Height = 120in[/tex]
Type B:
[tex]Initial\ Height = 4ft[/tex]
[tex]Initial\ Height = 4 * 12in[/tex]
[tex]Initial\ Height = 48in[/tex]
The height at any year from both trees is calculated using
[tex]Height = Iniital\ Height + Growth * x[/tex]
Where x represents the year;
For Type A:
[tex]Height = 120+ 19 * x[/tex]
[tex]Height = 120+ 19x[/tex]
For Type B:
[tex]Height = 48+ 25 * x[/tex]
[tex]Height = 48+ 25x[/tex]
To get when their height will be equal, we simply equate both expressions:
[tex]48+ 25x = 120 + 19x[/tex]
Collect Like Terms
[tex]25x - 19x= 120 - 48[/tex]
[tex]6x= 72[/tex]
Solve for x
[tex]x = 72/6[/tex]
[tex]x = 12[/tex]
Hence, It'll take 12 years

Answer:
for 7-12 plot the points on a graph. its the rise/run. from the point farthest to the left, go down or up until you are on the same horizontal line. however many units you moved is the first number. (_/?). then from that point, go to the right until to actually land on the point. however many units you used is your second number. The slope will be in a fraction, and sometimes you can turn it into a whole number.

Divers erected a cage in a shape of an upright cylinder on rhe ocean floor for protection. The diameter of the base measures 32 feet. How much space on the ocean floor does the cage have
Answer:
The cage will cover an area of 805 ft^2 on the Ocean floor
Step-by-step explanation:
To calculate the amount of space the cage has on the Ocean floor, we calculate the area of the base of the cylinder
Mathematically, that will be pi * d^2/4
= 22/7 * (32 * 32)/4
= 22/7 * 256 = 804.5714285714286
The cage will cover an area of 805 ft^2 on the ocean floor

The nth term of an AP is 12-4n. Find the first term and the common difference.
Answer:
first term is 8 and common difference d is -4
Step-by-step explanation:
nth term of an arithmetic sequence is: aₙ=12-4n
First term is putting n=1:
aₙ=12-4n
a₁=12-4(1)
a₁=12-4
a₁=8
So, first term a₁= 8
Now finding second term to find common difference
Second term is: n=2
aₙ=12-4n
a₂=12-4(2)
a₂=12-8
a₂=4
So, second term is: 4
The common difference is: a₂-a₁= 4-8 = -4
So, first term is 8 and common difference d is -4 if nth term is 12-4n
