Answer:
x = -14/5
Step-by-step explanation:
Given: 8^(3x+4) = 4^(2x-1)
Rewrite with same base: (2^3)^(3x+4) = (2^2)^(2x-1)
Use exponent rules: 2^(3(3x+4)) = 2^(2(2x-1))
Eliminate bases: 3(3x+4) = 2(2x-1)
9x+12 = 4x-2
5x+12 = -2
5x = -14
x = -14/5

What is the area of circle circumscribing a triangle?
An imaginary tangent line stretching from the triangle's two sides plus a section of the curve that is tangent to one side create this combination. The formula for the radius of a circle enclosing a triangle is
r = ABC / 4A.
Solution:
area of sector ABC = 85/360 × π × (7.3)² cm²
= 39.53 cm²
area of triangle ABC = 1/2 × 9 × 5.7 cm²
= 25.65 cm²
area of shaded region = area of sectot ABC ₋ area of triangle ABC
= 39.53 ₋ 25.65
= 13.88 cm²
Hence the area of shaded region is 13.88 cm²

Malik got a 200 cafe gift on January 1. He always orders decaf mochas which cost 5 each. At the end of January, maliks gift card has 125 left. Write an equation with x as your variable.
Answer:
200 - 5x = 125
Step-by-step explanation:
Let the number of orders made by Malik in the month of January = x
Each order costs = $5
Total cost of decaf mochas in one order = $5x
Malik had cake gift on 1st of January = $200
Amount of money left with Malik at the end of January = $125
Therefore, equation representing this situation will be,
200 - 5x = 125

Jersey village population in 1950 was 10,173. The population increases by 8.9% every 10 years. Predict the population in 2020
Answer:
Future Value= 18,478 people
Step-by-step explanation:
eGiving the following information:
Present value (PV)= 10,173
Growth rate (g)= 0.089 every 10 years
Number of periods (n)= 7
To calculate the population in 2020, we need to use the following formula:
FV= PV*(1 + g)^n
FV= 10,173*(1.089^7)
FV= 18,478 people

Step-by-step explanation:
If you know that cosine of the obtuse supplementary angle -0.3456 what can you determine about the acute angle
Answer:
69.8°
Step-by-step explanation:
Since cosФ = -0.3456
Ф = cos⁻¹(-0.3456)
Ф = 110.2°
Since the angles are supplementary, let the acute angle be x
So, x + 110.2° = 180°
x = 180° - 110.2°
x = 69.8°

Answer:
$65
Step-by-step explanation:
x is the number of items sold, and y is the profit, so we need to calculate
y = 35x - 250
where x=9
y = 35*9 - 250 = 315 - 250 = 65
So the total profit is 65 dollars
Mrs. Roberts sewed m shirts using 2 yards of cloth for each shirt. She also sewed (m+2) dresses, using 5 yards of cloth for each dress. A) How much cloth did she use altogether? Give your answer in terms of m. B) If m= 7, find how much more cloth she used to sew the dresses than the shirts.
Answer:
7m + 10
31 yards
Step-by-step explanation:
Shirts :
Number of shirts sewed = m
Yards of cloth used per shirt = 2 yards
Number of dresses sewed = m + 2
Yards of cloth used per dress = 5 yards
Cloth used altogether :
Cloths used for shirt = 2 * m = 2m
Cloth used for dress = 5 * (m+2) = 5m + 10
2m + (5m + 10) = 7m + 10
If m = 7
Cloth used for dress - Cloth used for shirt
(5(7) + 10) - (2(7))
(35+10) - 14
45 - 14 = 31 yards

The equivalent expression for the algebra m(n+p) is mn + mp.
What are equivalent expressions?Equivalent expressions are similar expressions that when being solved provide the same solution. Equivalent expressions are used widely in the expansion of algebraic equations.
From the given information, we have:
= m(n + p)
To determine the equivalent expression for the above algebraic equation, we need to expand the bracket as follows:
= m(n) + m(p)
= mn + mp

How do you find the mean, median, mode, and range of a set of numbers?
Answer:
You find the mean by adding all the numbers together then divide the sum of that by the amount of numbers there are. You find the median by looking at the middle number. You find the mode by looking at the most used number. You find the range by subtracting the highest and lowest numbers.
Step-by-step explanation:
say you have these numbers ( 8, 7, 17, 12, 0, 9, 11, 5, 8)
Mean:
8 + 7 + 12 + 17 + 0 + 9 + 11 + 5 + 8 = 77
77 ÷ 9 = 8.5
Median: 0
Mode: 8
Range: 17 - 0 = 17
Answer:
median is the middle number
but if the are two numbers in middle u add those two n divide by 2
range is the biggest number subtract lowest number
mean is total average divide by the number of data
mode is the number that appears many times

which expression can he used to find the surface area of the following sqare pyramid
Answer:
answer: A
Because when doing area for triangles its
base × height ÷ 2 so for 1 triangle it would be 5 × 4 = 20 then ÷ by 2 so 20 ÷ 2 = 10 Since there are 4 triangles we will have to add 10 4 times and then for the square it's easily just 4 × 4 = 16
so it would come out to 16 + 10 + 10 + 10 + 10 =
20-9x+4y+7-x
