Answer:
x = 13
Step-by-step explanation:
Since the two given angles are vertical angles, we know (5x) = 65.
Divide both sides by 5 : 5x = 65 and we get x = 13

Isabella invested $1300 in an account that pays 4.5% compounded annually. Assuming no deposits or withdrawals are made , find how much money Isabella would have in the account 14 years after her initial investment . Round to the nearest tenth.
Answer:
FV= $2,407.53
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 1,300
Interest rate (i)= 4.5% = 0.045
Number of periods (n)= 14 years
To calculate the future value (FV) of the initial investment after 14 years, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 1,300*(1.045^14)
FV= $2,407.53
A researcher conducts two studies on child health. In Study 1, 30 children consume either a low, moderate, or high-fat meal (n=10 per group). In Study 2, the researcher conducts the same study, except that a No Meal control group is added, with n = 10 in each group. If Fobt = 3.11 in both studies, then in which study will the decision be to reject the null hypothesis at a .05 level of significance for a one-way between-subjects ANOVA?
Answer:
The answer is "Study 2"
Step-by-step explanation:
In Study 2:
[tex]k =group\ number = 4\\\\df_1 = k - 1 = 4 - 1 = 3\\\\N = Total\ observations \ numbers = 30 + 10 = 40\\\\df_2 = N - k = 40 - 4 = 36\\\\Critical \ value( \alpha) (0.05,3,36) = 2.866\\\\Decision\ Rule\ in \ F \ test > F \critical, \ Then \ Reject H_0\\\\F \ test \ (3.11) < F \ critical \ (2.866)\\\\ \therefore H_0 \ is\ reject\\\\[/tex]
What is the gradient of the line that passes through the points (0,0) and (3,3)?
Answer:
1
Step-by-step explanation:
the gradient is a value that indicates how much the x value increases as the y value increases. It can be written as
rise/run
or
change in y value/change in x value
or
(y1-y2)/(x1-x2), where we know two coordinates (x1,y1) and (x2,y2).
We have two coordinates (0,0) and (3,3)
Therefore,
x1 = 0, y1 = 0
x2 = 3, y2 = 3
If we plug these values into the formula, it is [tex]\frac{3-0}{3-0} = \frac{3}{3} = 1[/tex]

What is the value of x?
A. 25°
B. 50°
C. 55°
D. 75°
E. 80°
Answer:
Option Bx = 50°Step-by-step explanation:
By the condition,
25° + 105° + x = 180° [Angle sum property of triangle]
=> 130 + x = 180
=> x = 180 - 130
=> x = 50° (Ans)

Your friend earns 7x dollars for
working x hours. How much does
your friend earn for working
16 hours? 40 hours?
16 hours $
40 hours $
Answer:
$112 for 16 hours
$280 for 40 hours
Step-by-step explanation:
Well, given that if 7x dollars are earned working for x hours (x is assumed to be 1), then $7 are earned for every hour worked. So we can pretty much multiply $7 (Money earned per hour) by 16 and then 40 (Hours worked). 7*16=112, and 7*40=280. And there are your two answers.
HELP PLZ DUE RN BRAINIEST TO WHOEVER RIGHT
Answer:
x = 11, -1
Step-by-step explanation:
First, let's identify what the quadratic formula is:
x = [-b ± √(b² - 4(a)(c))] / 2
Our equation is written in standard form:
ax² + bx + c = 0
x² - 10x - 11 = 0
Let's plug in what we know.
x = [-(-10) ± √((-10)² - 4(1)(-11))] / 2
Evaluate the exponent.
x = [-(-10) ± √(100 - 4(1)(-11))] / 2
Simplify the negatives.
x = [10 ± √(100 - 4(1)(-11))] / 2
Multiply.
x = [10 ± √(100 + 44)] / 2
Simplify the parentheses.
x = [10 ± √(144)] / 2
Simplify the radical (√)
x = [10 ± 12] / 2
Evaluate the ±.
x = [10 + 12] / 2
x = [22] / 2
x = 11
or
x = [10 - 12] / 2
x = [-2] / 2
x = -1
Your answers are x = 11, -1
Hope this helps!

Question 1: Imagine that we are measuring rain fall with a rain gauge. It is raining
at a rate of 1.25 inches per hour and after 5 hours, there are 6 inches of rain in the
gauge.
How much rain will be in the gauge in 11 hours
Answer:
13.5 inches
Step-by-step explanation:
after 5 hours = 6 inches
11 - 5 = 6 hours to go
1.25 x 6 = 7.5 inches
7.5 + 6 = 13.5 inches

Solve 14x + 8 = 22
help me!!
14x + 8 = 22. Okay, so first you want to subtract 8 from itself and 22. Once you did that you should get 14x = 14. Now, you need to divide 14 from both sides. 14/14 = 1. Meaning that x = 1. To check your answer, replace the x values with 1 and solve. 14 X 1 + 8 does equal 22.

use multiplication to solve the proportion
Answer:
Its 7.333333333333333333 (3 forever)
First you isolate y onto one side of the equation
y/9= 44/54 --> y = 9 x 44/54
Multiply the right side of the equation
9 x 44/54 = 396/54
Now divide to get the whole answer
396/54 = 7.3333333333 (3 forever)
y = 7.333333
