Answer:
He will only afford to rent the car for 4 days, he will spend 160 dolars to just have the car for 4 days. Since he plan to drive 125 miles, the cost for the miles will be 10 dolars. So if we add 160 (4 days with the car) plus 10 (for the miles) it would give 170.

Answer:
x = 9
Step-by-step explanation:
To solve for x, you must isolate the variable.
First, start by adding 2 to BOTH sides to eliminate the 2.
3=1/3x. then divide each side by 1/3
3÷1/3 = x
3/1 × 3/1 = x
9 = x
Jordan has a points card for a movie theater.
.
• He receives 85 rewards points just for signing up.
• He earns 10.5 points for each visit to the movie theater.
• He needs at least 240 points for a free movie ticket.
What is the least number of visits he needs to make in order to earn a free movie
ticket?
The least number of visits he needs to make in order to earn a free movie ticket is approximately 15 visits.
What is the least number of visits needed?Points received for signing up = 85 rewards points
Points received for each visit to the movie theater = 10.5 points
Points needed for a free movie ticket = 240 points
Number of visits = x
85 + 10.5x ≤ 240
10.5x ≤ 240 - 85
10.5x ≤ 155
x ≤ 155 / 10.5
x ≤ 14.761
Approximately,
x ≤ 15 visits
Therefore, Jordan needs at least 15 visits to earn a free movie ticket.

n + n+1 = 2n+1 = 2n+2-1 = 2(n+1) -1
2 = factor so must be even.
even number -1 is always odd
The value of n is 1/2 and it is not an even number or odd number
How to determine the solution to the equation?From the question, the steps are given as
n + n + 1 = 2n + 1
n + n + 1 = 2n+2-1
n + n + 1 = 2(n+1) -1
Also, from the question, we have the result of the expression to be
2
This means that
n + n + 1 = 2
Substitute n + n + 1 = 2(n+1) -1 in the equation n + n + 1 = 2
So, we have
2(n + 1) - 1 = 2
Add 1 to all sides of the equation
So, we have
2(n + 1) = 3
Divide both sides of the equation by 2
So, we have
n + 1 = 3/2
Subtract 1 from all sides
n = 1/2
The above implies that the number n is neither an even number, nor an odd number
This is so because the result is a fraction

the convex polygon below has 7 sides. find the value of x
Answer:
x = 147
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7 , then
sum = 180° × 5 = 900°
sum the interior angles and equate to 900
x + 141 + 112 + 129 + 106 + 139 + 126 = 900
x + 753 = 900 ( subtract 753 from both sides )
x = 147

What are the lengths of the hypotenuse and the long leg of the 30-60-90 right triangle?
Right triangles are triangles where one of its internal angles is a right angle, that is, has a measure of 90°. 30-60-90 triangles are right triangles whose internal angles have measures of 30°, 60° and 90°, respectively.
This kind of right triangles have the following features:
The long leg is adjacent to the least angle of the triangle, that is, the angle whose measure is 30°.The short leg is opposite to the least angle of the triangle, that is, the angle whose measure is 30°.The length of the long leg is √3 times the length of the short leg.The length of the hypotenuse is 2 times the length of the short leg.If we know that the short leg has a length of L, then the lengths of the long leg and the hypotenuse are √3 · L and 2 · L, respectively.

At the beginning of the year, Josue had $70 in savings and saved an additional $9
each week thereafter. Arianna started the year with $30 and saved $19 every week.
Let J represent the amount of money Josue has saved t weeks after the beginning of
the year and let A represent the amount of money Arianna has saved t weeks after
the beginning of the year. Write an equation for each situation, in terms of t, and
determine the interval of time when Josue has more in savings than Arianna.
There will be no interval of time when Josue has more in savings than Arianna, they have same savings is after 4 weeks
How to calculate the above question?Step one:
For Josue
initial savings balance= $70
weekly savings = $9
Let J represent amount of money Josue has saved and t the number of weeks after the beginning of the year
The total amount in the savings after t weeks is
J=9t+70-------1
For Arianna
initial savings balance= $30
weekly savings = $19
Let A represent the amount of money Arianna has saved and t the number of weeks after the beginning of the year
The total amount in the savings after t weeks is
J=19t+30---------2
Step two
equation 1 and 2 to find t
9t+70=19t+30
9t-19t=30-70
-10t=-40
divide both sides by 10
t=4
t=4 weeks
so after 4 weeks Josue and Arianna will have the same amount of money
For Josue t=4
J=9(4)+70-------1
J=36+70
J=$106
For Arianna t=4
A=19(4)+30---------2
A=76+30
A=$106
The two equations above shows that after 5 weeks their savings will be $106.

An 18 meters ladder is resting against a wall and makes an angle of 30° with the ground.
If the ladder is pushed vertically along the wall by a distance of x meters, the angle is
changed to 60° with the ground. The value of x is
A)9(√3 −1)
B) 2√3
c) ³(√3-1)
D) 9-√3
Answer:
A
Step-by-step explanation:
using the sine ratio and the exact values
sin30° = [tex]\frac{1}{2}[/tex] and sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]
calculate the height of the wall below x , call it h
the hypotenuse is the length of the ladder
using the sine ratio in the lower right triangle.
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{18}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2h = 18 ( divide both sides by 2 )
h = 9
lower part of the wall is 9 meters
using the sine ratio in the right triangle on the right
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9+x}{18}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2(9 + x) = 18[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
9 + x = 9[tex]\sqrt{3}[/tex] ( subtract 9 from both sides )
x = 9[tex]\sqrt{3}[/tex] - 9 = 9([tex]\sqrt{3}[/tex] - 1)
Answer:
[tex]\textsf{A)} \quad x=9(\sqrt{3}-1)[/tex]
Step-by-step explanation:
Interior angles of a triangle sum to 180°. Therefore, if the ladder makes an angle of 30° with the ground, the angle it makes with the wall is 60°.
Therefore, the two triangles are congruent as their corresponding angles are the same and the length of their longest side (hypotenuse) is the same.
30-60-90 Triangle Theorem
A 30-60-90 triangle is a special right triangle where the measures of its angles are in the ratio 1 : 2 : 3 and the measure of its sides are in the ratio 1 : √3 : 2.
The formula for the sides is b : b√3 : 2b where:
b = the side opposite the 30° angle (shortest leg).b√3 = the side opposite the 60° angle.2b = the side opposite the right angle (hypotenuse).Therefore, as the length of the hypotenuse is 18:
[tex]\implies 2b=18[/tex]
[tex]\implies b=9[/tex]
[tex]\implies b\sqrt{3}=9\sqrt{3}[/tex]
To find x, subtract the length of the shortest leg of the right triangle from the length of the other leg of the right triangle:
[tex]\implies x=9\sqrt{3}-9[/tex]
[tex]\implies x=9(\sqrt{3}-1)[/tex]

10. What is m/ABD in the figure shown?
The measure of m∠ABD in the figure shown is 19°.
Given:
∠BCD = 71°
In the figure, ΔABC is an isosceles triangle where AB = BC.
According to the Isosceles Triangle Theorem, an isosceles triangle has equal angles on either side of its equal sides.
So, ∠BAD = ∠BCD = 71°
The sum of angles in a triangle sums to 180°.
∠ABC + ∠BAD + ∠BCD = 180°
∠ABC + 71° + 71° = 180°
∠ABC + 142° = 180°
∠ABC = 180° - 142° = 38°
DB is the angle bisector of ∠ABC.
Now, ∠ABD = ∠CBD = 38°/2 = 19°
The measure of ∠ABD is 19°.

The product of negative four and a number is at most
negative sixty-two. Choose al possible values of the number.
The possible values of the number will be -62/4 or -31/2.
Multiplication of numbers may be defined as the tool or arithmetic operation which can be used to increase the count of a number. For example, if there is a number 4, then in order to increase the number it will be multiplied with some other number like 9. Now, the number will be 4×9 = 36. We are given that the product of -4 with a number gives the answer as 62. Let us assume the number as x and form the equation in accordance with the data given in the question.
-4×(x) = 62
Now, to find x we divide -4 on both the sides and we get
x = -62/4
