Answer:
x=3
z=65
Step-by-step explanation:
6x+97 and 14x+73 are vertical angles which means they are equal
6x+97= 14x+73
Subtract 6x from each side
6x-6x+97= 14x-6x+73
97 = 8x +73
Subtract 73 from each side
97-73 = 8x+73-73
24 = 8x
Divide each side by 8
24/8 = 8x/8
3 = x
Now we need to find z
6x+97 and z are supplementary angles which means they add to 180
6x+97 +z = 180
6(3) +97 +z = 180
18+97+z=180
Combine like terms
115+z = 180
Subtract 115 from each side
115-115 +z=180-115
z = 65
A printer prints fewer than 18 pages per minute. What is the maximum number of pages the printer can print in 7 minutes?
Answer:127 pages of paper
Step-by-step explanation:
18 times 7
The maximum number of pages the printer can print in 7 minutes is 119 pages, assuming it prints at the upper limit of 17 pages per minute.
To find the maximum number of pages the printer can print in 7 minutes, we multiply the maximum number of pages it can print per minute by the number of minutes.
Given:
- The printer prints fewer than 18 pages per minute.
- Number of minutes: 7
Let's use the upper limit of the printer's speed, which is 17 pages per minute (since it prints fewer than 18 pages per minute).
Maximum number of pages printed in 7 minutes:
[tex]\[ \text{Pages} = \text{Pages per minute} \times \text{Minutes} \][/tex]
[tex]\[ \text{Pages} = 17 \times 7 \][/tex]
[tex]\[ \text{Pages} = 119 \][/tex]
So, the maximum number of pages the printer can print in 7 minutes is 119 pages.

a delivery company charges an extra fee for a package that weighs more than 100 pounds write an inequality that shows the weight w, in pounds, of a package that sonia can ship without having to pay the extra fee
Answer:
[tex]w\leq 100\ pounds[/tex]
Step-by-step explanation:
Let
w------> the weight in pounds
we know that
A delivery company charges an extra fee for a package that weighs more than 100 pounds
so
For
[tex]w> 100\ pounds[/tex] -----> the company charges an extra fee
therefore
For
[tex]w\leq 100\ pounds[/tex] ----> the company not charge an extra fee
The inequality w ≤ 100 expresses the weight limit for Sonia's package. Jesse should use kilograms to weigh the box in the mailroom.
The inequality is: w ≤ 100
Since Sonia can ship packages without paying the extra fee for weights up to 100 pounds. Therefore, any package weighing 100 pounds or less would not incur the additional charge.
Jesse should use kilograms to weigh the box of books in the mailroom because it's a more appropriate metric unit considering the size and weight of the objects in the box.
You’ve saved $90 towards the cost of a gaming console. you plan to save an additional 10.50 per week. if the console coasts $300 how many weeks will you have to have to save $10.50 before you have enough money to buy the console?
You subtract 90 from the 300 dollar goal and you’re left with $210. If you then divide that by 10.50 the answer will be 20. So the answer is 20 weeks.
For what value of a do the lines 5x–2y=3 and x+y=a intersect at a point on the y-axis?
So what they are trying to say is that they both have the same y-intercept. Easy!
Make y the subject:
5x - 2y = 3
2y = 5x - 3
y = 2.5x - 1.5
The y-intercept is -1.5.
Make y the subject:
x + y = a
y = -x + a
Therefore, a must be -1.5 !
The system of linear equations has a solution on the y-axis only when a = -3/2
When the system has one solution?
We have the system of linear equations:
5x - 2y = 3
x + y = a
Now let's write both in slope-intercept form:
y = (-3/2) + (5/2)x
y = a - x
If we want the lines to intersect at the y-axis, then we will have x = 0, replacing that we get:
y = -3/2
y = a
So, for the system to be consistent, we must have a = -3/2.

You are standing 50 meters from a hot air balloon that is preparing to take off. The angle of the elevation to the top of the balloon is 28. Find the height of the balloon
Answer:
27m
Step-by-step explanation:
The diagram is shown in the attachment.
The height of the hot air balloon is calculated using the tangent ratio.
The tangent ratio involves the side length that is opposite(h) to the given angle (28) and the side length adjacent to the angle.
[tex]\tan 28\degree=\frac{h}{50}[/tex]
This implies that;
[tex]h=\50tan 28\degree[/tex]
[tex]h=26.585m[/tex]
The height is 27m to the nearest meters.
Using the tangent of the angle of elevation, the height of the hot air balloon is calculated to be approximately 26.585 meters.
Explanation:To find the height of the hot air balloon, we can use trigonometric principles, specifically the tangent function, which relates the angle of elevation to the opposite side (the height of the balloon in this case) and the adjacent side (the distance from you to the balloon).
The angle of elevation to the top of the balloon is given as 28 degrees and the distance from the observer to the balloon is 50 meters. Using the formula for tangent:
tan(angle) = opposite/adjacent
In this case:
tan(28 degrees) = height/50 meters
Therefore, to find the height:
height = 50 meters * tan(28 degrees)
Calculating this using a calculator:
height ≈ 50 * 0.5317
height ≈ 26.585 meters
So, the height of the balloon is approximately 26.585 meters.
Determine the unknown side of the similar triangle. A) 2 B) 3 C) 4 D) 5
Step-by-step explanation:
You didn't provide any context so I can't answer this. BUT!!
If you're looking at two triangles, look for the side corresponding to the unknown side. If it's an equilateral (all sides same length) triangle no need to worry. It's probably a scalene, all different lengths, because math is hard. So you'll have 3 different lengthy sides, and you can probably see which ones correspond with which based on length and position. You can use angles to help you.
Now use the sides you have the value of to determine scale factor.
Divide the length of one of the sides on one triangle by the corresponding side on the other. That's your scale factor. Now multiply it by the side that corresponds to the unknown side, and that is supposed to be your length.

55^2 = 50^2 + 35^2 − 2(50)(35)cos(A)
Answer:
A = 78.46
Step-by-step explanation:
55^2 = 50^2 + 35^2 − 2(50)(35)cos(A)
3025 = 2500 + 1225 - 3500 cos A
- 3500 Cos A = -3725 + 3025
-3500 cos A = -700
cos A = -700/-3500
= 0.2
A = cos^-1 0.2
A = 78.46
Answer:
A=78.46° (to 4sf)
Step-by-step explanation:
The only way to approach this problem is to solve the equation.
55²=50²+35²-2(50)(35)cos(A)
3025=2500+1225-3500cosA
3025=3725-3500cosA
Now collecting like terms together:
3025-3725=-3500cosA
-700=-3500cosA
CosA=0.2
A=78.46° (to 4sf)

An 8-car Ferris wheel is shaped like a regular octagon. Does the Ferris wheel have rotational symmetry?
Answer:
Yes, it does.
Step-by-step explanation:
Every regular shaped figure will have rotational symmetry, since they are built with identical segments all around.
To find the answer, ask yourself « If I rotate the shape, is there a time where I’ll find the exact same shape again with a different angle? »
So, a square has rotational symmetry, but not a rectangle.
A equilateral triangle has rotational symmetry, but not any other type of triangle.
The Ferris wheel shaped like a regular octagon would have rotational symmetry.
What is rotational symmetry?The rotational symmetry of a shape makes it possible for an object when rotated on its own axis, the shape of the object looks the same.

write an equation in slope intercept form for the line that passes through (4, -4) and is parallel to 3x+4x=2y-9
Answer:
[tex]\large\boxed{y=\dfrac{7}{2}x-18}[/tex]
Step-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
Convert the equation of a line 3x + 4x = 2y - 9 to the slope-intercept form:
[tex]3x+4x=2y-9[/tex]
[tex]7x=2y-9[/tex] add 9 to both sides
[tex]7x+9=2y[/tex] divide both sides by 2
[tex]\dfrac{7}{2}x+\dfrac{9}{2}=y\to y=\dfrac{7}{2}x+\dfrac{9}{2}[/tex]
Parallel lines have the same slope. Therefore we have the equation:
[tex]y=\dfrac{7}{2}x+b[/tex]
Put the coordinates of the point (4, -4) to the equation:
[tex]-4=\dfrac{7}{2}(4)+b[/tex]
[tex]-4=7(2)+b[/tex]
[tex]-4=14+b[/tex] subtract 14 from both sides

Multiply. Write your answer in simplest form. −2/3 x(2 1/2 )x(−3)=
Answer:
The correct answer is 5
Step-by-step explanation:
To find this, start by multiplying them in any order. For ease, we'll multiply the first and last.
-2/3 * -3 = 2
Now we take that and multiply it by the remaining term.
2 * 2 1/2 = 5
Final answer:
Multiplying −2/3 by 2 1/2 and then by −3 results in the answer 5 after converting the mixed number to an improper fraction, considering the signs during multiplication, and simplifying the result.
Explanation:
To multiply the given numbers and write the answer in simplest form, let's break down the math step by step.
Firstly, convert the mixed number 2 1/2 into an improper fraction. To do this, multiply the whole number by the denominator of the fraction and add the numerator. This gives us 2 x 2 + 1 = 5, so 2 1/2 becomes 5/2.
Now, let's look at the multiplication operation:
−2/3 × (5/2) × (−3) = ( −2 × 5 × −3 ) / ( 3 × 2 )
When multiplying, we multiply the numerators together and the denominators together, which results in:
(−2 × 5 × −3) / (3 × 2) = (+2 × 5 × 3) / 6 = 30 / 6
When considering the signs, remember that when two numbers with the same sign multiply, the result is positive (e.g., −2 × −3 = +6), and when two numbers with opposite signs multiply, the answer is negative (e.g., −3 × 2 = −6).
The final step is to simplify the fraction 30/6, which simplifies to 5, since 30 divided by 6 equals 5.
Therefore, the answer is 5.
