Answer:
68 and 70
Step-by-step explanation:
if the first integer is x, the next would be x + 2
so your equation is x + x+2 = 138
2x + 2 = 138
minus 2 on both sides
2x =136
x = 68
so if x is 68
x + 2 would be 70
if you add those up, im pretty sure you'll get 138

Please help this question finding a side on a triangle
Answer:
The side of the hypotenuse is 12.233 centimeters.
Step-by-step explanation:
The triangle presented in the figure represents a right triangle, we know an angle and a leg adjacent to such angle and we need to determine the length of the hypotenuse, which is found by this trigonometric relation:
[tex]\cos 56^{\circ} = \frac{7.4\,cm}{x}[/tex] (1)
Where [tex]x[/tex] is the length of the hypotenuse, measured in centimeters.
Then, we clear the variable within (1):
[tex]x = \frac{7.4\,cm}{\cos 56^{\circ}}[/tex]
[tex]x = 13.233\,cm[/tex]
The side of the hypotenuse is 12.233 centimeters.

If $25,000 is borrowed with an interest of 8.0% compounded annually, what is the total amount of money needed to pay it
back in 10 years?
Round your answer to the nearest cent.
Do NOT round until you have calculated the final answer.
Answer: $45,000= Interest
Total= 45,000+ P. P=25000
=70000
Step-by-step explanation:
The total amount of money $53,973 is needed to pay it back in 10 years.
What is compound interest rate?Compound interest is computed as interest on the principle of an account plus any accrued interest.
Compound interest can be calculated using the following formula:
x = P (1+r/n[tex]) ^{nt}[/tex] - P
,where x = compound interest
P = principal (the initial deposit or loan amount)
r = annual interest rate
n = the number of compounding periods per unit of time
t = the number of time units the money is invested or borrowed for
The given principal amount is $25,000.
And an interest of 8.0% compounded annually.
And time period is 10 years and n = 1.
x = 25000 ( 1 + 8/10 )¹⁰ - 2500
x = $53973.12
x = $53,973
Therefore, the total amount of money $53,973 is needed to pay it back in 10 years.

A survey is conducted to determine the percentage of students at state universities who change their major at least once. In a SRS of 100 students 78% indicated that they graduated with a major different from the one with which they entered college. Determine a 95% confidence interval for the percentage of students who change their major.
Answer:
95% confidence interval for the percentage of students who change their major
(0.69881 , 0.86119)
Step-by-step explanation:
Step(i):-
Given that the sample size 'n' = 100
Given that the sample proprtion
p = 78% = 0.78
Level of significance =0.05
Critical value Z₀.₀₅ = 1.96
Step(ii):-
The 95% of confidence interval is determined by
[tex](p^{-} -Z_{0.05} \frac{\sqrt{p(1-p)} }{\sqrt{n} } , p^{-} +Z_{0.05} \frac{\sqrt{p(1-p)} )}{\sqrt{n} })[/tex]

Here is a balanced hanger.
1. Write an equation representing this hanger.
2. Find the weight of one circle. Show or explain how you found it.
25
Answer:
the weight of one circle is 6.25
Step-by-step explanation:
25 divided by 4=6.25
Check:
6.25x4=25
4w=25 is the equation which represents the hanger and weight of one circle is 6.25 units.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
A hanger stays balanced when the weights on both sides are equal.
The hanger has four circles on left hand side and value 25 on the right hand side
By equating both we get
w+w+w+w=25
4w=25
4w=25 is an equation representing this hanger.
Now let us find the weight of one circle
Divide both sides by 4
w=25/4
w=6.25
Hence, 4w=25 is the equation which represents the hanger and weight of one circle is 6.25 units.

The ratio of the measures of the sides of a triangle is 3:5:7, and its perimeter is 135 feet. Find the measure of each side of the triangle.
a. x = 9
b. 13.5 ft, 22.5 ft, 31.5 ft
c. 27 ft, 45 ft, 63 ft
d. 25 ft, 45 ft, 65 ft
Answer:
The correct answer is C. 27 ft, 45 ft, 63 ft.
Step-by-step explanation:
Given that the ratio of the measures of the sides of a triangle is 3: 5: 7, and its perimeter is 135 feet, in order to find the measure of each side of the triangle, the following calculation must be performed:
3 + 5 + 7 = 15
135/15 = 9
9 x 3 = 27
9 x 5 = 45
9 x 7 = 63
Therefore, the measures of the sides of the triangle are 27 ft, 45 ft, and 63 ft.
