Find m
A.)38
B.)22
C.)52
D.)12
Answer:
x =12
Step-by-step explanation:
The two angles add to 90 degrees
4x+4 + 5x-22 = 90
Combine like terms
9x - 18 = 90
Add 18 to each side
9x -18+18 = 90+18
9x = 108
Divide each side by 9
9x/9 = 108/9
x =12
Answer:
C.) 52°
Step-by-step explanation:
find x first
4x + 4 + 5x - 22 = 90
9x - 18 = 90
9x = 108
x = 12
plug it into the expression
4(12) + 4
= 48 + 4
= 52°

Solve the logarithmic equation . Round the answer to four decimal places . 2^x =25
Answer:
x = 4.6439
Step-by-step explanation:
2^x =25
Take the log of each side
log 2^x = log 25
We know that log a^b = b log a
x log 2 = log 25
Divide each side by log 2
x = log 25 / log 2
x =4.643856
Rounding to 4 decimal places
x = 4.6439
Answer:
x = 4.6439
Step-by-step explanation:
[tex]2^{x} =25log 2^x = log 25\\log 2 = log 25x = log 25 / log 2\\x =4.643856\\x = 4.6439[/tex]
1. There are 5 red , 7 blue and 6 green biros in a packet. What is probability of a boy picking a green or red biro closing his eyes ?
2. In a basket of fruits, there are 6 grapes , 11 bananas and 13 oranges. if one fruit is chosen at random , what is the probability that the fruit is either a grape or banana ?
Answer:
It should be self-explanatory if you look at the numbers#1
P(green or red) = (5 + 6)/(5 + 7 + 6) = 11/18 or 61.11%#2
P(grape or banana) = (6 + 11)/(6 + 11 + 13) = 17/30 or 56.67%Answer:
1.) P( green or red ) = 11 /18
2.) P ( grapes and bnaa ) = 17 / 30
Step-by-step explanation:
1 .) Probability of boy picking a green or red bior closing his eyes
= sum of red and green biros / Total no. of biros in a packet.= 5 + 6 / 5 + 7 + 6
P( green or red ) = 11 /18
2.) Probability of that the fruit is either a grape and banana , P ( grapes and banana)
= Sum of grapes and banana / total no. of fruits in basket.P ( grapes and banana ) = 6 + 11 /6 +11 +13
P ( grapes and banana ) = 17 / 30

use the zero property to determine the solutions for (2x + 6)(x - 7) = 0.
Need help asap please
Answer:
x = -3
x = 7
Step-by-step explanation:
If either term is zero the product is zero
(2x + 6)(x - 7) = 0
2x + 6 = 0
2x = -6
x = -3
x - 7 = 0
x = 7
Tristan records the number of customers who visit the store each hour on a Saturday. His data representing the first seven hours are 15, 23, 12, 28, 20, 18, and 23. How many customers visited the store during the eighth hour if the median number of customers per hour did not change?
16
19
20
23
Answer:
20
Step-by-step explanation:
The number of Customers that visited the store during the eight hour if the median number of customers didn't change is; C: 20
What is the Median?We are given the data representing the first seven hours as; 12, 15, 18, 20, 23, 23, 28. Here; n=7
Thus;
Median = (n + 1)/2 = (7 + 1)/2
Median = 4th term
Thus, the median is 20.
When one data is added, n = 8. Thus;
Median will be the average of the 4th and 5th term. Since the median does not change, it means that the median number of customers per hour is still 20.

Find the SUm of the infinite series.
I'll do problem 13 to get you started.
The expression [tex]4\left(\frac{2^n}{7^n}\right)[/tex] is the same as [tex]4\left(\frac{2}{7}\right)^n[/tex]
Then we can do a bit of algebra like so to change that n into n-1
[tex]4\left(\frac{2}{7}\right)^n\\\\4\left(\frac{2}{7}\right)^n*1\\\\4\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{0}\\\\4\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{1-1}\\\\4\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{1}*\left(\frac{2}{7}\right)^{-1}\\\\4*\left(\frac{2}{7}\right)^{1}\left(\frac{2}{7}\right)^n*\left(\frac{2}{7}\right)^{-1}\\\\\frac{8}{7}\left(\frac{2}{7}\right)^{n-1}\\\\[/tex]
This is so we can get the expression in a(r)^(n-1) form
a = 8/7 is the first term of the geometric sequencer = 2/7 is the common ratioNote that -1 < 2/7 < 1, which satisfies the condition that -1 < r < 1. This means the infinite sum converges to some single finite value (rather than diverge to positive or negative infinity).
We'll plug those a and r values into the infinite geometric sum formula below
S = a/(1-r)
S = (8/7)/(1 - 2/7)
S = (8/7)/(5/7)
S = (8/7)*(7/5)
S = 8/5
S = 1.6

Answer in fraction form = 8/5

The total cost f(x), in dollars, for renting a vacation house for x days is shown:
f(x) = 10 + 250x
What does f(10) represent?
The number of dollars it costs for 10 people to rent the house
The number of houses that can be rented for 10 days
The number of days the house can be rented for a cost of $250
The number of dollars it costs to rent the house for 10 days
Answer:
260 of dollars it costs to rent the house for 10 days
The number of dollars it costs to rent the house for 10 days
Step-by-step explanation:
F(x) = 10 + 25x
F(10) = 10 + 25*(10)
F(10) = 10 + 250
F(10) = 260 of dollars it costs to rent the house for 10 days
Here f (10) represent 260 of dollars it costs to rent the house for 10 days
Given that,
The equation is f(x) = 10 + 250x.
Based on the above information, the calculation is as follows:
F(x) = 10 + 25x
= 10 + 25(10)
= 10 + 250
= 260 of dollars it costs to rent the house for 10 days

Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
Answer:
x=19/4
Step-by-step explanation:
perimeter is the sum of all sides
so
perimeter given is 34 = (x+2)+(x+2)+(3x-4)+(3x-4)
34=8x-4
34=8x
x=34/8 which reduces to 19/4

if f(x) = -4x+3 and g(x) = 3 +2x-4 find (f+g) (x)
Answer:
Please be careful with your typing [f(x)=-sqrt(x)+6 ... right? g(x)=-4*sqrt(x)-3 ... or -4*sqrt(x)+3 ... one or the other, right?
If so, you are dilating by a factor of 4, -1 versus -4 as multiplier of sqrt(x); and, translating up 3 units (6 versus 3) or 9 units (6 versus -3).
Step-by-step explanation:
Answer:
-2x+2
Step-by-step explanation:
f(x) = -4x+3 and g(x) = 3 +2x-4
Note what you put for g(x) simplifies to 2x-1
(f+g) (x) = -4x+3+ 3 +2x-4

The process of solving the inequality will be: -2(5 - 4x) < 6x - 4 8x - 10 < 6x - 4 -6 < -2x x > 3 This is in accordance to the rule of solving inequalities which states that whenever we multiply or divide by a negative number while solving an inequality, we must reverse the inequality sign.Store a sells fabric for 3.00 per yard Store b sells packages of fabric for 3.00 The cost of fabric at either can be modeled by the function c(t)=3t where t is the number of yards of fabric at store a and t is the number of packages of fabric at store b The domain of c(t)=3t is all real numbers
Answer:
[tex]0 \le t < \infty[/tex]
Step-by-step explanation:
Given
[tex]c(t) = 3t[/tex]
Required
The domain
From the question, we understand that t represents number of yards/packages (depending on the store)
This means that:
[tex]t \ge 0[/tex] ---- the start value
[tex]t < \infty[/tex] --- the end value
Rewrite [tex]t \ge 0[/tex] as [tex]0 \le t[/tex]
So, we have: [tex]0 \le t[/tex] and [tex]t < \infty[/tex]
Hence, the domain is: [tex]0 \le t < \infty[/tex]
