Which expression shows the result of applying the distributive property to 7(x + 11)?
Answer:
7x+77
Step-by-step explanation:
7(x+11)
=(7)(x+11)
=(7)(x)+(7)(11)
=7x+77
The equivalent expression from the distributive property is 7x+77.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the expression is 7(x + 11). From the distributive property, the expression will be calculated as:-
E = 7(x+11)
E=(7)(x+11)
E=(7)(x)+(7)(11)
E=7x+77
Therefore, the equivalent expression from the distributive property is 7x+77.

Christy spent 25 of her money on a shirt. She has $21.75 left. How much did she spend on the shirt?
A. $8.70
B. $7.25
C. $14.50
D. $29
Christ spent a total amount of $ 14.50 on the shirt.
Finding the amount spent on the shirt
Here we use the linear equation concept to solve the problem.
Since we do not know the amount that Christ has assume that with a variable and form a linear equation using the data given.
Now solve the resultant equation for the value of the variable and find the amount spent by Christ on the shirt as given below
Here we have
Christy spent 2/5 of her money on a shirt.
She has $21.75 left
Let 'x' be the amount that Christy has
From the data,
Christy spent 2/5 of her money on a shirt.
Amount spent by Christy = 2/5 of x = 2x/5
Remaining amount = x - 2x/5
From the data,
Chrisy is left with $ 21.75
=> x - 2x/5 = 21.75
=> 3x/5 = 21.75
=> 3x = 108.75
=> x = 36.25
Amount the that she spent 2x/5 = 2 (36.25)/5 = 14.50
Therefore,
Christ spent a total amount of $ 14.50 on the shirt.

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius. Use 3.14 for pi and round your answer to the nearest hundredth. (Hint: You may only enter numerals, decimal points, and negative signs in the answer blank)
Answer:
volume = 254.34 cubic inches
Step-by-step explanation:
r = diameter /2 = 6/2 = 3 in
h = 3 × r = 3 × 3 = 9
volume = pi× r^2 × h

Answer:
only C is non-linear
Step-by-step explanation:
A linear equation is of the form;
y = mx + c
we have single powers of x and y; also, there is no product of x and y
Thus, we have;
a; 12x + 3y = 7
y =( -12x + 7)/3
this shows we have a linear equation
b. y + x = 4x + 5
y = 4x-x + 5
y = 3x + 5
This is a linear equation
c. y = 8/x^2
This is non-linear; we already have one power of x as 2
Find m∠STU and m∠TUA
Answers:
angle STU = 65 degreesangle TUA = 123 degrees=========================================================
Explanation:
Let's find the expression for angle TUS in terms of x
Angle TUA has the expression 11x+2. It will add to angle TUS to get 180 degrees
(angle TUS) + (angle TUA) = 180
angle TUS = 180 - (angle TUA)
angle TUS = 180 - (11x + 2)
angle TUS = 180 - 11x - 2
angle TUS = -11x + 178
Now focus on the interior angles of triangle TUS. We have these three angles
T = 5x+10U = -11x+178S = 58For any triangle, the interior angles always add to 180, so,
T+U+S = 180
(5x+10) + (-11x+178) + (58) = 180
(5x-11x) + (10+178+58) = 180
-6x + 246 = 180
-6x = 180-246
-6x = -66
x = -66/(-6)
x = 11
Use this x value to find the angle measures we're after:
angle STU = 5x+10 = 5*11+10 = 55+10 = 65 degreesangle TUA = 11x+2 = 11*11+2 = 121+2 = 123 degrees--------------------------
As an alternative route, you can apply the remote interior angle theorem. This says that adding two interior angles leads to the exterior angle that isn't adjacent to either one.
In this case, we would say
(angle STU) + (angle TSU) = angle TUA
that leads to the equation
(5x+10) + (58) = 11x+2
Solving this should lead to x = 11 to generate the angles mentioned earlier.

i hope that this is what you are looking for^_^
This is just a fancy way your teacher saying that when you have an equation y=[tex]4^{x}[/tex]+1, what is y when x=-1,0,3.
We just need to solve by substituting the x in respectively.
x=-1, y=[tex]\frac{5}{4}[/tex]

if an ordered pair was added to the table, which of the following pairs would result in the table becoming not a function.
Please help
Answer:
C or D
Step-by-step explanation:
✔️If the ordered pair (8, 3) was added to the table, we would have two one input value, 8, having two different outputs, 4 and 3 respectively. The table therefore ceases to be a function. Each input value in a function must have only one output value. Otherwise, it ceases to be a function.
✔️Also, if we look at other options, we would see that we also have another orders pair that can make the table not to be function anymore once it's added to the table.
The ordered pair (-3, 4), when added, will make us have one input value, -3, having two output values, 4 and 6 respectively. This will make the table not to become a function.
✔️Therefore, there are two correct options, they are C or D.

A couch was originally priced $500 dollars and on sale for 70% off what is the price for after the discount
Answer: the answer would be $150
Step-by-step explanation:
Answer:$150.00
Step-by-step explanation:
If you think about a item going down by 70%, it means that you are paying only 30% of the total price.
100%-70%=30%
So 30% of $500 is what you are paying.
30%=30/100=0.3
So you multiply 0.3x500
Which is equal to 150

C) 17/20
Step-by-step explanation:
In the center of a growing city is an old church and a high-rise office building separated by a plaza. Two surveyors are collaborating on the job of determining how high the tip of the church spire is above the plaza. Each surveyor has a theodolite mounted on a tripod. One surveyor is in the entrance way of the high-rise. The top of his tripod is 165cm above plaza level. The second surveyor is directly above the first, and (amazingly) the top of her tripod is exactly 100m above the top of her colleague's tripod. The first surveyor measures the angle of elevation of the tip of the spire as 50∘. The second surveyor measures the angle of depression of the tip of the spire as 30∘. (The diagram on the right is not drawn to scale. Points A and F are at plaza level. You'll have to supply all the necessary measurements on the diagram for yourself.)

You work at a frozen yogurt shop during the summer. You need to order 5-ounce and 8-ounce cups. The storage room will only hold 10 more boves. A box of 5 ounce cups cost $100 and a box of 8-ounce cups costs $150. A maximum of 1200 is budgeted for yogurt cups. Write a system of linear inequalities that shows the number of bonus of 5 ounce and 8 ounce cups that could be bought. Graph your result
Answer: 5 Boxes
The way i did it: f+e =10
Value equation...:100f+150e=1250
Modify:100f+100e=1000
Substract the 1st from the 2nd to solve for e
50e=250
e=5 boxes
f+e=10 so f equals 5 boxes
