Answer:
x = 1953125
Step-by-step explanation:
log x - log 5^3 = 2 log 5^3
log x - 3 log 5 = 6 log 5
log x = 9 log 5 = log 5^9
x = 5^9
x = 1953125

2 people A and B travel from x and y talong different routes.Their journeys take the same amount of time
Question:
2 people A and B travel from X to Y along different routes. Their journeys take the same amount of time. B's route is 100km at an average speed of 40km/hour A's route is 60km. What is A's average speed?
Answer:
Person A's average speed is 24km/hr
Step-by-step explanation:
Given
Person B
[tex]Distance = 100km[/tex]
[tex]Speed = 40km/hr[/tex]
Person A
[tex]Distance = 60km[/tex]
Required
Average speed of person A
Speed is calculated as:
[tex]Speed = \frac{Distance}{Time}[/tex]
For person B
[tex]40 = \frac{100}{Time}[/tex]
Make Time the subject
[tex]Time= \frac{100}{40}[/tex]
[tex]Time= 2.5hr[/tex]
For person A
[tex]Speed = \frac{Distance}{Time}[/tex]
[tex]Speed = \frac{60}{Time}[/tex]
The journeys last for the same duration.
So;
[tex]Speed = \frac{60}{2.5}[/tex]
[tex]Speed = 24[/tex]
Person A's average speed is 24km/hr

Find the measure of each angles:
Answer:
10. 123º
13. 65º
Step-by-step explanation:
For number 10, a straight line is equal to 180º so all we have to do is subtract 57 (the number that we're given) from 180
For number 13, vertical angles are always congruent (the same) so we know that it's 65º

hey guys could yall solve this problem for me? thanks
Answer:
Given ABCD ~ EFGH
FG = BC(EF/AB)
FG = 7(9/6)
FG = 63/6
FG = 10.5
GH = CD(EF/AB)
GH = 11(9/6)
GH = 99/6
GH = 16.5
EH = AD(EF/AB)
EH = 12(9/6)
EH = 108/6
EH = 18
Please please help I swear I will give you brainlist if it’s right and please explain for part a and part b thank you
Answer:
A. Reduction
B. 2
Step-by-step explanation:
A: A reduction is when the image is getting smaller. The apostrophes show the new, or second, image. It is called "prime." Because the prime is smaller than the original, it is a reduction.
B: Scale factor is when you divide, which number changes it. In other words, the image moved from 4 to 2, from 2 to 1, etc, which means we are DIVIDING by 2.

Find the amount necessary to fund the given withdrawals.
Semiannual withdrawals of 270$ for 6 years, interest rate is 6.2% compounded semiannually
Answer:
the amount that necessary to fund is $2,671.61
Step-by-step explanation:
The computation of the amount is shown below;
Given that
PMT = $270
NPER = 6 × 2 = 12
RATE = 6.2% ÷ 2 = 3.1%
FV = $0
The formula is shown below:
=-PV(RATE;NPER;PMT;FV;TYPE)
After applying the above formula the present value is $2,671.61
hence, the amount that necessary to fund is $2,671.61

Write an equation in point slope form that is parallel to AB with endpoints A (2, -1) and B (4, 5) that goes through the point (1.5, 4)
Answer:
[tex]y = 3x - 0.5[/tex]
Step-by-step explanation:
Given
Goes through
[tex]C = (1.5,4)[/tex]
Parallel to AB
[tex]A = (2,-1)[/tex]
[tex]B = (4,5)[/tex]
Required
Determine the line equation
First, calculate the slope of AB
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{5--1}{4-2}[/tex]
[tex]m = \frac{6}{2}[/tex]
[tex]m = 3[/tex]
The line is said to be parallel to AB. This implies that their slopes are equal.
The equation of the line is then calculated as:
[tex]y = m(x - x_1) + y_2[/tex]
Where:
[tex](x_1,y_1) = (1.5,4)[/tex]
So:
[tex]y = 3*(x - 1.5) + 4[/tex]
[tex]y = 3x - 4.5 + 4[/tex]
[tex]y = 3x - 0.5[/tex]

Abox has a shape of a rectangular prism. The base of the box measures 12 square inches. The height of the box measures 7 inches. Which is the volume of the box?
A. 558 cube in.
B. 252 in.
C. 84 cube in.
D. 19 cube in.
Answer: C.
Step-by-step explanation: To find the volume of something, you multiply the length, width, and height together. Since they have already multiplied the length and width together to form the base, multiply 7 by 12 (base times height) to get 84 cubic inches.
