Can someone help me rnnn please??
Answer:
No, they are the same triangles
Step-by-step explanation:
They both have a side length of 3 and 5 and an angle that measures 60 degrees. The triangles are just flipped in different directions.
If they were to draw an additional triangle that would make it seem different, they could expand the angle and make it obtuse to get a triangle with 1 wide corner.

WHAT HAPPENS WHEN NON-METALLIC ELEMENTS ARE COMBINED
5x + y = -3
x + 4y = 26
Slove this using elimnation
Answer:
x=-2 y=7
Step-by-step explanation:
Multiple -5 for the second equation to get -5x-20y=-130. Adding -5x-20y=-130 to 5x+y=-3 should get you -19y=-133. Divide both sides by -19 to get y=7. Subsitute 7 in for y for the first equation. Subtract 7 on both sides to get 5x=-10. Divide both sides by 5 to get x=-2. So, x=-2 and y=7.

D, 1056 Cubic inches
Step-by-step explanation:
Multiply 11x16 to get the 2-d area of it's base. after multiply by 8 to get its hieght. You have the volume of the shape with the step-down filled. To find the volume with the step down empty, divide by 4 to get the area of 1/4. then multiply by 3 to find 3/4 of the rectangular prism
{[(11×16×8)÷4]3} <== Equation
x = 12 − y
2x + 3y = 29
Your local dry cleaners is running a special. The dry cleaner is offering a 13% discount for any drop off that is over $40. Also, they are running a neighborhood special of an additional 5% off. Given this information, determine the decay factor corresponding to each percent decrease.
a.
34.8; 33.06
c.
0.87; 0.95
b.
0.384; 0.3306
d.
87; 95
Answer:
a. 34.8; 33.06
Step-by-step explanation:
The computation is shown below;
since in the question it is mentioned that that if the price is $40 so if offered the 13% discount
So the 13% discount on $40 is
= $40 - 13% of $40
= $34.80
Now additional 5% is also provided
So,
= $34.80 - 5% of $34.80
= $33.06
Therefore the first option is correct

A watercolor painting is 25 inches long by 12 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 3 inches to each side of the length and the width. What is the area of the mat?
Answer:
the area of the mat = total area added minus the original area of the water color painting.
Step-by-step explanation:
length of the mat is:L = 20 in + 1 in + 1 in because 1 in is added to each sideL = 22 inwidth of the mat is:w = 9 in + 1 in + 1inw = 11 in
Area mat = (22 in x 11 in) - ( 20 in x 9 in)
area mat = 62 sq in is the area of the mat

You are traveling in a car. Your speed is 30 miles per hour. What is your speed in feet per minute?
Answer:
.5
Step-by-step explanation:
30 miles a hour divide by 60 so your going half a mile a minute
Your speed in feet per minute is 2640 ft/min.
What is unit rate?A unit rate means a rate for one of something.
Given that, Your rate of speed is 30 miles for every 1 hour
We know, 1 mile = 5280 feet
Therefore, 30 miles = 30x5280 = 158400 feet
That means, you are travelling 158400 feet for every hour
In an hour, there are 60 minutes,
Therefore, you are travelling 158400 feet in every 60 minutes.
In 60 minutes = 158400 feet
In 1 minute = 158400/60 = 2640 feet
That means you are travelling 2640 feet in every 1 minute.
Hence, your speed in feet per minute is 2640 ft/min.

Someone please help asap!!! It’s due in 45 minutes, how am I supposed to know where to shade when doing these?
Answer:
If you want to know the process on how to graph and shade, start by graphing the inequalities. Assume that the inequality signs are just =, so the equation is y=mx+b. Let's use 1) as an example. When the sign is < or >, it's a dotted line. If the sign is ≥ or ≤, it's a solid line. Once you're done graphing the inequalities, choose a random coordinate on the graph. Let's use (0,0). Now, plug in the x- and y-value into the equations. 0<-6(0)+3 and 0≤0-2. Simplify it to get 0<3 and 0≤-2. Because the inequality is true for y<-6x+3, you would shade the side of the graph that includes (0,0). Because the inequality isn't true for y≤-x-2, you would shade the side of the graph that doesn't include (0,0). The shaded parts of both inequalities should overlap somewhere and that's the area you need to officially shade.
Here's the worked example:

I was looking for 4(x-4), but 4(x-2)(x+2) also works
Answer:
4(x - 2)(x + 2) (Answer B)
Step-by-step explanation:
4x^2 - 16 is the difference of two squares, a case in which there is a simple formula to remember: a^2 - b^2 = (a - b)(a + b)
4x^2 - 16 = (2x - 4)(2x + 4)
This can be further simplified: 2(x - 2)(2)(x + 2) = 4(x - 2)(x + 2) (Answer B)

Find a polynomial f(x) of degree 5 that has the following zeros. 1, 8, -7, 5, -4. Leave your answer in factored form
Answer:
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)
Step-by-step explanation:
The zeros of the function are written in the form
f(x) = (x-a)(x-b)..... where the a,b are the zeros
f(x) = (x-1) (x-8) (x - -7)(x-5) ( x--4)
Rewriting
f(x) = (x-1) (x-8) (x +7)(x-5) ( x+4)

what does mrs freeman pay for the meal
Answer:
Lin's father pay for the meal is $18.19
Step-by-step explanation:
Given:
Lin’s father is paying for a $20 meal.
He has a 15%-off coupon for the meal.
After the discount, a 7% sales tax is applied.
Now, to get the amount Lin's father pay for meal.
So, we deduct the 15% discount first:
$20 - 15% of $20.
Then, adding 7% sales tax:
$17 + 7% of $17
Therefore, Lin's father pay for the meal is $18.19.
