The angle ∠14 and angle ∠16 are the supplementary angles. Then the measure of angle ∠16 will be 188° – 5x.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
The line l and the line m are parallel to each other.
The angle ∠7 = 4x – 3 and angle ∠14 = 5x – 8.
Then the measure of angle ∠16 will be
The angle ∠14 and angle ∠16 are the supplementary angles. Then we have
∠14 + ∠16 = 180°
5x – 8 + ∠16 = 180°
∠16 = 180° – 5x + 8
∠16 = 188° – 5x

Step-by-step explanation:
using the rule of logarithms
[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] , then
y = [tex]log_{3}[/tex] (x + 2) - 1
to find the zero let y = 0 , that is
[tex]log_{3}[/tex] (x + 2) - 1 = 0 ( add 1 to both sides )
[tex]log_{3}[/tex] (x + 2) = 1 , then
x + 2 = [tex]3^{1}[/tex] = 3 ( subtract 2 from both sides )
x = 1
the zero is (1, 0 )

( help pls )
Answers
Answer:
5
Step-by-step explanation:
Original equation:
[tex]7(2)^x=224[/tex]
Divide both sides by 7
[tex]2^x=32[/tex]
Rewrite in log
[tex]log_232=x[/tex]
You can do mental math to realize this equals 5, or plug this into your calculate (if it allows you to set the base), but if you can't do either, you can use the change of base formula:
[tex]log_ba=\frac{log (a)}{log(b)}[/tex]
You get:
[tex]log_232=\frac{log(32)}{log(2)}[/tex]
When you calculate using a calculator you should get 5
Answer: x = 5
Step-by-step explanation:
[tex]7(2)^x=224[/tex]
start by dividing 7 from both sides
[tex]\frac{7(2)^x}{7} =\frac{224}{7}[/tex]
[tex]2^x=32[/tex]
take the log of both sides
[tex]log(2^x) = log(32)[/tex]
move the x to the left of the log
[tex]xlog(2) = log(32)[/tex]
divide both sides by log(2)
[tex]x=\frac{log(32)}{log(2)}[/tex]
use change-of-base formula
[tex]\frac{log(a)}{log(b)} =logx_{b} (a)[/tex]
[tex]x = log_{2} (32)[/tex]
since [tex]2^5 = 32[/tex], x = 5

What is the ratio of the two values and what new value do they produce?
$280 in 7m
(Write Explaination)
Answers
The required ratio is give by $40/m, 4 miles/min, 30 mile/liter. .
Let, just assume a vehicle is given an economy of $280 of 7m.
What is the Ratio?
The ratio can be defined as the comparison of the fraction of one quantity towards others. E.g.- water in milk.
Now,
The ratio can be given as for economy = 280/7
= $40/m
here for new values,
suppose the vehicle travel for 40miles in 10 mins
ratio = 40/10= 4 miles/min
and vehicle consumes 2 liter fuel on 60 miles of distance ratio can be given as
ratio = 60/2 = 30 mile/liter.
Thus the required ratios can be given as $40/m, 4 miles/min, 30 mile/liter.

Marlon jogs two miles to the park in 25 minutes, turns around, and takes another 55 minutes to walk the same path back to his house. What is his average speed for the round-trip?
Answers
Answer:
3 mph
Step-by-step explanation:
So the average speed is simply: [tex]\frac{distance}{time}[/tex]. In case, the total time is 25 minutes + 55 minutes which is a total of 80 minutes, or 1.33 hours. The total distance traveled is two miles + two miles, since he jogged two miles to the park, and then he turns around and walks the same path. So in total he traveled 4 miles. Plugging this in to the formula gives you the equation: [tex]\overline{v}=\frac{4 \text{ miles}}{\frac{4}{3}\text {hours}}=\frac{4\text{ miles}}{1}*\frac{3}{4}\text{ hours} = 3mph[/tex]

(1 point
Answers
The first five months Paul paid and in the next seven months he paid 24.
What is a Discount ?Discounts are defined as lowered prices or the sale of an item for less than it would typically cost. The fundamental formula for calculating a discount is to multiply the original price by the given percentage rate in decimal form. We must deduct the discount from the original price to determine the item's sale price. A discount is an amount that is subtracted from the regular price of an item.
Paul represent his plan in the form of equation:
[tex]5 x+7(x+8.50)=245.50[/tex]
Where x is an amount for the first [tex]5[/tex] months that is paid by Paul after the discount and [tex](x+8.50)[/tex] is an amount for the next [tex]7[/tex] month after discount.
[tex]&\Rightarrow \quad 5 x+7 x+59.50=245.50 \\&\Rightarrow \quad 12 x=186 \\&\Rightarrow \quad x=\frac{186}{12} \\&\Rightarrow \quad x=15.50\end{aligned}[/tex]
For the next 7 month:
[tex](x+8.50)=(15.50+8.50)=\$ 24[/tex]
