So essentially an adjacent angle is when two angles have a common side and a common vertex.
So knowing that we can determine from the picture all the adjacent angles:
D) <2 and <3 are adjacent angles
E) <1 and <3 are adjacent angles
F) <1 and <5 are adjacent angles

Step-by-step explanation:
which integer is greater.
l-5l or l3l
Answer:
|-5|
Step-by-step explanation:
When you see the absolute value signs and a number in between, that number is always going to be the positive version of that number (if the number is already positive, it stays positive)So, |-5| = 5, and 5 is greater than 3, therefore |-5| is greater than |3|I hope this helps!
#12 Eva took out a 5-year loan to buy a car at a 2% simple interest rate. If she has to pay $1,200 in interest, how much principal did she borrow? *
Answer:
$12,000
Step-by-step explanation:
2% for 5 years is 10% in total. if after the 5 years she gotta pay 1200, this mean 0.1p=1200
multiply 10 on both sides to find p, or principal.
p=12000
Answer:
$12,000
Step-by-step explanation:
P = 1200 / ( 0.02 × 5 ) = 12000
P = $ 12,000.00

Jackie runs and dances for 75 minutes every day.
She dances 25 minutes more than she runs.
Part A: Write a pair of linear equations to show the relationship between the
number of minutes Jackie runs (x) and the number of minutes she dances (y)
every day.
Part B: How much time does Jackie spend running every day? Show your work.
Part C: Is it possible for Jackie to have spent 45 minutes dancing every day?
Explain your reasoning.
Answer: A. x + y = 75 B. She spends 25 minutes running and 50 minutes dancing every day. C. Yes it is.
Step-by-step explanation: B. She spends 25 minutes running and 50 minutes dancing every day, because if she dances for 25 more minutes then she runs then we can minus 25 from 75 which we get 50. Then we take the 50 a divide it by 2 because of the two categories dancing and running. So we know she spends 25 minutes running then 25 minutes dancing but we need to add the 25 minutes to dancing. So she spends 25 minutes running and 50 dancing. C. Yes it is because she already dances for 50 minutes a day so all she needs to do is workout for 10 minutes less so 65 minutes one day.
A system of linear equation consists of multiple linear equations
The system of linear equations is: [tex]\mathbf{x + y = 75}[/tex] and [tex]\mathbf{y = 25 + x}[/tex]She spends 25 minutes runningIt is possible to dance 45 minutes every day(a) A pair of linear equations
She dances and runs for 75 minutes.
So:
[tex]\mathbf{x + y = 75}[/tex]
She dances 25 minutes more than she runs.
So:
[tex]\mathbf{y = 25 + x}[/tex]
So, the system of linear equations is: [tex]\mathbf{x + y = 75}[/tex] and [tex]\mathbf{y = 25 + x}[/tex]
(b) The time she spends running every day
Substitute 25 + x for y in [tex]\mathbf{x + y = 75}[/tex]
[tex]\mathbf{x + 25 + x = 75}[/tex]
Subtract 25 from both sides
[tex]\mathbf{2x = 50}[/tex]
Divide both sides by 2
[tex]\mathbf{x = 25}[/tex]
Hence, she spends 25 minutes running
(c) Is it possible to dance 45 minutes each day
We have:
[tex]\mathbf{y = 25 + x}[/tex]
So:
[tex]\mathbf{y = 25 + 45}[/tex]
[tex]\mathbf{y = 70}[/tex]
This means that, she has to spend less minute running and dancing.

Linda is riding on a bike course that is 60 miles long. So far, she has ridden 54 miles of the course. What percentage of the course has Linda ridden so far?
Answer:
Linda has ridden 90% of the course
Step-by-step explanation:
To find the percentage the formula is
distance ridden so far/total distance X 100
54/60 X 100
= 0.9 X 100
= 90
=90%
Therefore Linda has ridden 90% of the course.

Find the measure of each acute angle.
(19x - 1)
(13x - 5)
(193' - 1) =
and (132 – 5)° =
Answer:
(19x - 1)° = 56°
(13x - 5)° = 34°
Step-by-step explanation:
Property of the interior angles of a triangle:
Sum of interior angles of a triangle is 180°.
Therefore, sum of angles of the given right triangle will be,
(19x - 1)° + (13x - 5)° + 90° = 180°
32x - 6 + 90 = 180
32x = 96
x = 3
(19x - 1)° = 19×3 - 1 = 56°
(13x - 5)° = 13×3 - 5 = 34°

Answer:
$26.80
Step-by-step explanation:
multiply 1.79 by 5 and you get 8.95
multiply 1.19 by 15 now because there are 15 uncounted bags left and you get 17.85
add together and you get 26.8. she spent 26.8 dollars on candy

Fairfield Homes is developing two parcels near Pigeon Fork, Tennessee. In order to test different advertising approaches, it uses different media to reach potential buyers. The mean annual family income for 15 people making inquiries at the first development is $150,000, with a standard deviation of $40,000. A corresponding sample of 25 people at the second development had a mean of $180,000, with a standard deviation of $30,000. Assume the population standard deviations are the same.
1. State the decision rule for 0.05 significance level: H0: μ1 = μ2; H1:μ1 ≠ μ2.2. Compute the value of the test statistic
Answer:
The decision rule is
Reject the null hypothesis
The test statistics is [tex]t = -2.699[/tex]
Step-by-step explanation:
From the question we are told that
The first sample size is [tex]n_1 = 15[/tex]
The mean at first deployment is [tex]\= x _1 = \$ 150 000[/tex]
The standard deviation is [tex]s_1 = \$ 40000[/tex]
The second sample size is [tex]n_2 = 25[/tex]
The mean at second deployment is [tex]\= x_2 = \$ 180000[/tex]
The standard deviation is [tex]s_2 = \$ 30 000[/tex]
The null hypothesis is [tex]H_o : \mu_1 = \mu_2[/tex]
The alternative hypothesis is [tex]H_a : \mu_1 \ne \mu_2[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df =n_1 + n_2 -2[/tex]
=> [tex]df =40 -2[/tex]
=> [tex]df =38[/tex]
Generally the pooled variance is mathematically represented as
[tex]s_p^2 = \frac{x(n_1 -1) s_1^2 + (n_2 - 1)s_2^2}{df}[/tex]
=> [tex]s_p^2 = \frac{(15 -1) 40000^2 + (25 - 1)30000^2}{38}[/tex]
=> [tex]s_p^2 = 1.1579 * 10^{9}[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{ \= x_1 - \= x_2 }{\sqrt{s_p [\frac{1}{n_1} + \frac{1}{n_2} ]} }[/tex]
=> [tex]t = \frac{ 150000 - 180000 }{\sqrt{1.11579 *10^{9} [\frac{1}{15} + \frac{1}{25} ]} }[/tex]
=> [tex]t = -2.699[/tex]
Generally from the t distribution table the probability corresponding to the t statistics value to the left is
[tex]t_{-2.699 , 38} = 0.00516046[/tex]
Generally the p -value is mathematically represented as
[tex]p-value = 2* t_{-2.699, 38}[/tex]
=> [tex]p-value = 2* 0.00516046[/tex]
=> [tex]p-value = 0.01032[/tex]
From the obtained value we see that the [tex]p-value < \alpha[/tex] hence
The decision rule is
Reject the null hypothesis
