can you please not delete this? im actually VERY confused and would like people to not just delete anything i ask : ) and to the person who deleted my question, im asking for people to explain it, not answer for me.
Explanation:
The green, light blue, and red bars all indicate scores that are 70 or higher.
We add up the heights of those bars to find out how many people passed.
green bar = height of 2light blue bar = height of 5red bar = height of 1So 2+5+1 = 8 people passed.
Unfortunately 2 people (dark blue bar) got below 70 so they didn't pass.

13) Seven more than the quotient of a number and 2 is 10.
14) Five less than twice a number is 7.
15) One less than the product of four and a number is 11.
16) Six less than six times a number is 12.
17) Ten more than the quotient of a number and 3 is 12.
18) Seven more than twice a number is 1.
19) The sum of 9 and the quotient of x and 7 is 11.
20) The product of 8 and the difference of n and 3.
Answer:
13) 7 + x/2 = 10
14) 2x - 5 = 7
15) 4x - 1 = 11
16) 6x - 6 = 12
17) x/3 + 10 = 12
18) 2x + 7 = 1
19) 9 + x/7 = 11
20) 8(n - 3)
Step-by-step explanation:
The quotient of x and 2 = x ÷ 2 = x/2
The product is the result of multiplying two or more other numbers
The sum is the result of adding two or more numbers
The difference is the result of subtracting one number from another
13) 7 + x/2 = 10
14) 2x - 5 = 7
15) 4x - 1 = 11
16) 6x - 6 = 12
17) x/3 + 10 = 12
18) 2x + 7 = 1
19) 9 + x/7 = 11
20) 8(n - 3)
Freddie needs to buy 3 dozen cookies for a party. The first 20 cookies cost $0.27 each. The rest cost $0.17 each.
How much will Freddie spend on cookies?
$2.72
$5.40
$8.12
$9.72
Answer:
$8.12 is the total amount Freddie will spend on the cookies.
Step-by-step explanation:
3 dozen = 36 cookies
20 x $0.27= $5.4
we still need 16 more cookies
16 x $0.17= $2.72
add $5.4 and $2.72 together. which = $8.12
Does the equation r = 3 represent a function? Choose one option from each drop-down menu to explain your answer. For an equation to represent a function, multiple different inputs cannot have the same outputs The equation x = 3 represents a function because! Choose... inputs have Choose... outputs. Choose... the same multiple different
Answer:
This relation is NOT a function. In order for an equation to represent a function, every x in the range of the function must only have one y -value.
only answer if yk how to do this
Answer:
x = 25
scalene, acute
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
[tex]\implies (2x+11)+(3x-7)+(2x+1)=180[/tex]
[tex]\implies 2x+11+3x-7+2x+1=180[/tex]
Collect like terms:
[tex]\implies 2x+3x+2x+1+11-7=180[/tex]
Combine like terms:
[tex]\implies 7x+5=180[/tex]
Subtract 5 from both sides:
[tex]\implies 7x=175[/tex]
Divide both sides by 7:
[tex]\implies x=25[/tex]
Substituting found value of [tex]x[/tex] into the three angle expressions:
∠A = (2 x 25) + 11 = 61°
∠B = (3 x 25) - 7 = 68°
∠C = (2 x 25) + 1 = 51°
This is a scalene triangle as it has three different angles and three different side lengths (non-congruent).
It is also an acute triangle as all interior angles are less than 90°

5/13 = t - 6/13 PLS ANSWER ASAP
Step-by-step explanation:
[tex] \frac{5}{13} = t - \frac{6}{13} [/tex]
[tex]t - \frac{6}{13} = \frac{5}{13} [/tex]
[tex]t = \frac{5}{13} + \frac{6}{13} [/tex]
[tex]t = \frac{11}{13} [/tex]
Answer:
t = 83/13
Step-by-step explanation:
5/13 = t-6
1.Add 6 to both the side of the equation
5/13 +6 = t -6 + 6
t =83/13

Last night, the two dinner specials at Aisha's favorite restaurant were salmon filet and steak. The restaurant served 55 specials in all, 40% of which were salmon filets. How many salmon filets did the restaurant serve?
Answer:
22 salmon filets.
Step-by-step explanation:
First of all, the restaurant served 55 specials.
You would then take 40% of 55 and you would get 22. (or do 0.4 x 55)
The 40% were the salmon filets, and so you get your answer.
the other 60% are steaks, but we aren't looking for that.

Answer:
49
Step-by-step explanation:
PEMDAS
Parentheses first or as symbols, ( and ), Exponents next, and there are no exponents, then Multiplication and Division from left to right, and lastly, Addition and Subtraction from left to right.
5 x (6 + 4) - 1
=5 x (10) - 1
=5 x 10 - 1
=50 - 1
=49
Answer:
49!
Step-by-step explanation:
PEMDAS
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
Start with parentheses, so 6+4. 10.
Then your equation is 5 x 10 - 1.
Then Multiplication, since there are no exponents- 5 x 10 = 50.
Then since there’s no division, skip to addition.
Since there is no addition either go to subtraction, 50 - 1.
50 - 1 = 49.
5 x (6 + 4) - 1 = 49
pls help me i dont understand
Answer:
1. Because every angle on the opposite of 6 and 7 are corresponding to those 2 angles, meaning they are going to be the same value.
2. The sum of the listed angles 6, 7, 10 and 11 is 360 degrees because they are all right angles.
3. In a parallelogram the the opposite angles are congruent, and the sum of the interior are all an equal number, adding up to 360, each being 90 degrees on its own.

Answer: the answer to #3 is a= 4
Step-by-step explanation:
I have to answer each question with a separate box
Answer:
3) a = 4
4) m = 10
5) x = 2
6) (correct as is)
9) t = 14
Step-by-step explanation:
3:
Step 1: Add 4 to both sides.
[tex]8+4=3a-4+4[/tex] [tex]12=3a[/tex]Step 2: Divide both sides by 3.
[tex]12/3 = 3a/3[/tex] [tex]a = 4[/tex]4:
Step 1: Subtract 9 from both sides.
[tex]m/5 + 9 - 9 = 11 - 9[/tex] [tex]m/5 = 2[/tex]Step 2: Multiply both sides by 5.
[tex]m/5 * 5 = 2 * 5[/tex] [tex]m = 10[/tex]5:
Step 1: Subtract 13 from both sides.
[tex]13+7x-13=27-13[/tex] [tex]7x=14[/tex]Step 4: Divide both sides by 7.
[tex]7x/7 = 14/7[/tex] [tex]x=2[/tex]6: (correct as is)
9:
Step 1: Subtract 5t from both sides.
[tex]42+5t-5t=8t-5t[/tex] [tex]42=3t[/tex]Step 2: Divide both sides by 3.

what is the constant term in the expression 6 x 3^y + 8x^2 + 5x + 7
Answer:
The constant term is 7
Answer:
Step-by-step explanation:
The constant term is 7. this is because x and y are unknowns and change depending on the other. As 6x^3y will change depending on what x or y is so will: 8x^2 and 5x therefore 7 is the constant term.
On a piece of paper, use a protractor to construct △ABC with m∠A=30° , m∠B=60° , and m∠C=90° .
Which statements about the triangles are true?
Select each correct answer.
AC BC
AC>AB
Answer:
BC > AC and BC < AB.
Step-by-step explanation:
Given that,
To construct △ABC with m∠A=30°, m∠B=60°, and m∠C=90°.
We have to find,
The statements about the triangles are true.
According to the question,
In △ABC
This means that the side opposite to the right angle in the triangle is AB.
Since, the side opposite to the right angle is the hypotenuse and is the longest side of the triangle, thus AB cannot be shorter than any other side of the triangle.
Then, BC < AB.
And, In the triangle △ABC ,
tan60° =
tan60° =
By comparing the equations,
Then, BC > AC
Hence, The required correct statement in △ABC are BC > AC and BC < AB
Answer:
ac<ab & ac>bc
