JJ decides to leave a tip that is 15% of the original price for his meal. How much should he leave as tip for the $5.50 cheeseburger and $2.50 milkshake? Express your answer to the hundredths place?
Answer: $9.20
Step-by-step explanation: To get the answer, you add both the cost and multiply it by .15. Then you add the product to the number you got adding the cost of the food.
Answer:
$1.20
Step-by-step explanation:
He has to leave 100% of the cost which is $5.50 + 2.50 or $8.00.
He wants to leave 115% of the $8 he has to leave.
So you set it up like
x/8 = 115/100
Then you solve for x
8(115) = 920
920/100 =9.2
So he will leave $9.20.
It then asks for just how much the tip is that he will leave so
9.2 - 8 = 1.2
So the tip is $1.20.
1. 4 2/3 x 4/5
2. 8⋅2−7−5
3. 7(6+8)−4
4. 10−2+(6⋅2−4)

A rectangle has a width of 9 units and a length of 40 units. What is the length of a diagonal? 31 units 39 units 41 units 49 units
Answer: 41 units
Step-by-step explanation: took the quiz
The length of the diagonal is 41 units.
To find the length of a diagonal.
What is rectangle?A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.
Let a right triangle with legs length 9 units and 40 units and hypotenuse is the diagonal length c.

What is X2 + 3(4) - 1 = 47?
Answer:
x=6, -6
Step-by-step explanation:
take the root of both sides then solve
Answer:
x = 18
Step-by-step explanation:
2x + 3(4) - 1 = 47
Begin by combining your like terms
2x + 12 - 1 = 47
2x + 11 = 47
Isolate your variable (x) by using inverse operations
2x = 36
x = 18
Simplify the following expression five to the power of -3
The tens digit of a two digit number is five more than the units digit. Seven times the sum of the digits of this number is 3 less than the number itself. Find the number.
Answer:
94
Step-by-step explanation:
Let the unit's digit = [tex]y[/tex]
Let the ten's digit = [tex]x[/tex]
Then the number will be equal to [tex]10x+y[/tex]
Now, using the given statement:
[tex]x=y+5 ..... (1)[/tex]
[tex]7(x+y) = 10x+y-3\\\Rightarrow 7x+7y=10x+y-3\\\Rightarrow 6y-3x=-3 ..... (2)[/tex]
Now, using the equation (1) in equation (2):
[tex]6y-3(y+5) =-3\\\Rightarrow 3y-12=0\\\Rightarrow y =4[/tex]
By equation (1):
[tex]x = 4+5 \\\Rightarrow x =9[/tex]
Therefore, the number is :
[tex]10x+y= 10\times 9 +4 = \bold{94}[/tex]

The graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2 what is the zero of f ?
Answer:
Check the explanation.
Step-by-step explanation:
As the graph of a linear function f passes through the point (-2,-10) and has a slope of 5/2.
As the slop-intercept form is given by:
[tex]y = mx+b[/tex]
where m is the slope and b is the y-intercept.
substituting the values (-2, -10) and m = 5/2 in the slop-intercept form to determine y-intercept.
[tex]y = mx+b[/tex]
[tex]-10=\frac{5}{2}\left(-2\right)+b[/tex]
[tex]-\frac{5}{2}\cdot \:2+b=-10[/tex]
[tex]-5+b=-10[/tex]
[tex]-5+b+5=-10+5[/tex]
[tex]b=-5[/tex]
And the equation of the line in the slope-intercept form will be:
[tex]y = mx+b[/tex]
putting b = -5 and slope = m = 5/2
[tex]y = mx+b[/tex]
[tex]y=\frac{5}{2}x+\left(-5\right)[/tex]
[tex]y=\frac{5}{2}x-5[/tex]
Determining the zero of function.
As we know that the real zero of a function is the x‐intercept(s) of the graph of the function.
so let us determine the value of x (zero of function) by setting y = 0.
[tex]0=\frac{5}{2}x-5[/tex]
[tex]\frac{5}{2}x-5=0[/tex]
[tex]\frac{5}{2}x=5[/tex]
[tex]5x=10[/tex]
[tex]x=2[/tex]
Therefore, the zeros of the function will be:

Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa can Ben make with 5/6 cup of green chilies
Answer:
The number of batches Ben can make with 5/6 cup of green chilies is [tex]2\frac{1}{2}[/tex] batches of salsa.
Step-by-step explanation:
From the question,
Ben needs 1/3 cups of chilies for a batch of salsa.
To determine how many batches of salsa he can make with 5/6 cup of green chilies,
Let the number of batches Ben can make with 5/6 cup of green chilies be x.
Now,
If 1/3 cups of green chilies is needed for 1 batch,
Then, 5/6 cups of green chilies will make x batches
1/3 × x = 5/6 × 1
x = 5/6 ÷ 1/3
x = [tex]\frac{5}{6} \div \frac{1}{3}[/tex]
x = [tex]\frac{5}{6} \times \frac{3}{1}[/tex]
x = [tex]\frac{15}{6}[/tex]
x = [tex]\frac{5}{2}[/tex]
x = [tex]2\frac{1}{2}[/tex]
Hence, the number of batches Ben can make with 5/6 cup of green chilies is [tex]2\frac{1}{2}[/tex] batches of salsa.

Help i need to past this test to get my permit
Answer:
See below for answers
Step-by-step explanation:
1st Problem:
Because the figure is a triangle, it's interior angles will add up to 180 always. Since it's a right triangle, we know one of the angles is 90, but we'll need to set up an equation to solve for x.
90+(2x-2)+(x+5)=180
2x-2+x+5=90
3x+3=90
3x=87
x=29
Therefore, B) 29, is the correct answer
2nd Problem:
Given side lengths of a, b, and c, if a+b<c, then it's a triangle. Since 8+8 is not less than 16, the sides do not make a triangle. The hypotenuse, c, must always be the longest length.
Therefore, A) Not a triangle, is the correct answer
3rd Problem:
To find angle x, we need the last interior angle of the triangle. Since the interior angles of a triangle add up to 180, we once again set up an equation to find the missing interior angle:
21+34+y=180
55+y=180
y=125
Since the missing interior angle is 125 degrees, it is supplementary to angle x, where supplementary angles add up to 180 degrees as well. So we would subtract 125 from 180 to get x. 180-125=55, so angle x is 55 degrees. Therefore, C) 55, is the correct answer.
4th Problem:
Again, use the Interior Angle Theorem to get x:
58+47+x=180
105+x=180
x=75
Therefore, A) 75, is the correct answer
5th Problem:
3,4,5 is a Pythagorean Triple, so it is a right triangle as 3^2+4^2=5^2. It is also scalene because none of the sides are equal to each other.
Therefore, B) Yes, scalene, is the correct answer
