Answer:
11a. 3,117
11b. 33
Step-by-step explanation:
11a. -165 + 3217 + 65
The easiest way to do this would be,
-165 + 65 = -100 than -100 + 3217
-100 + 3217 is the same as 3217 - 100
-100 + 3217 = 3,117
11b. 173 + (-43) + (-97)
this is the same as 173 - 43 - 97
173 - 43 = 130 and 130 - 97 = 33
Tram Fancy Balloons has offered to sell its balloon bouquet for a fixed down payment of $30 and an additional charge of $3 25 per bouquet
Write an algebraic rule that will determine the cost of "c" balloon bouquets
Answer:
y = 30 + 3.25c
(where y is the total cost in dollars, and c is the number of balloon bouquets)
Step-by-step explanation:
Let y = total cost (in dollars)
Let c = number of balloon bouquets
Given:
Fixed payment = $30Charge per bouquet = $3.25⇒ y = 30 + 3.25c
Y inetercept:-
Fixed payment=30Rate of change=3.25

Answer: Choice C
f(x) = x+5
===========================================
Explanation:
The input x = -3 has 5 added to it to get x+5 = -3+5 = 2
The diagram shows the "-3" in the input oval pointing to "2" in the output oval.
Through similar steps, we have the input -2 map to the output 3. Also, the input 0 points to the output 5.
The input -5 should map to 0, but 0 isn't in the output list. So we ignore -5 in the input oval.
Estimate the difference of 621 - 267
by rounding to the nearest hundred.
Answer:
300
Step-by-step explanation:
621 rounds to 600 because 21 is smaller than 50. 267 round to 300 since 67 is bigger than 50.
600-300=300
A local road has a grade of 10%. The grade of a road is its slope expressed as a percent. Find the slope of the road as a fraction, and then simplify.
Answer:
1/10
Step-by-step explanation:
You can convert a percentage to a fraction by dividing it by 100%.
__
10% = 10%/100% = 10/100 = 1/10

What’s the chord BC?
Answer:
D) 3.8 cm
Step-by-step explanation:
There are several ways this problem can be solved. Maybe the easiest is to use the Law of Cosines to find angle BAC. Then trig functions can be used to find the length of the chord.
__
In triangle BAC, the Law of Cosines tells us ...
a² = b² +c² -2bc·cos(A)
A = arccos((b² +c² -a²)/(2bc)) = arccos((8² +6² -3²)/(2·8·6)) = arccos(91/96)
A ≈ 18.573°
The measure of half the chord is AB times the sine of this angle:
BD = 2(AB·sin(A)) ≈ 3.82222
The length of the common chord is about 3.8 cm.

Another solution can be found using Heron's formula to find the area of triangle ABC. From that, its altitude can be found.
Area ABC = √(s(s-a)(s-b)(s-c)) . . . . where s=(a+b+c)/2
s=(3+8+6)/2 = 8.5
A = √(8.5(8.5 -3)(8.5 -8)(8.5 -6)) = √54.4375 ≈ 7.64444
The altitude of triangle ABC to segment AC is given by ...
A = 1/2bh
h = 2A/b = 2(7.64444)/8 = 1.911111
BD = 2h = 3.822222

Using an exponential function, it is found that there will be 8290 landlines in 5 years.
What is an exponential function?A decaying exponential function is modeled by:
[tex]A(t) = A(0)(1 - r)^t[/tex]
In which:
A(0) is the initial value.r is the decay rate, as a decimal.In this problem, we have that the initial value and the decay rate are given as follows:
A(0) = 25300, r = 0.2.
Hence the function is given by:

Coordinate pairs are organized like (x,y).
x tells us the location of the point in relation to the x-axis, the axis that is horizontal.y tells us the location of the point in relation to the y-axis, the axis that is vertical.To determine a coordinate pair, we can determine each coordinate individually, then put them together.
Solving the QuestionNotice how the red point sits on the very edge of the graph.
When we look at the x-axis, we can see that it occurs at the number 0 on the x-axis. In other words, the red point occurs when x=0.
When we look at the y-axis, we can see that it lines up with the number 2. In other words, the red point occurs when y=2.
Therefore, when we put the two coordinates together like (x,y), we get (0,2).

Which property is illustrated by the following statement? A. Reflexive B. Commutative C. Transitive D. Symmetric
Answer:
D. Symmetric
Step-by-step explanation:
The symmetric property of congruence says, for objects A and B, ...
if A ≅ B, then B ≅ A.
__
The symmetric property of congruence makes your statement true:
if ΔHXA ≅ ΔRGI, then ΔRGI ≅ ΔHXA
__
Additional comment
The other answer choices involve other properties:
Reflexive -- an object is congruent to itself: ΔHXA ≅ ΔHXA
Commutative -- certain operations allow the order of their operands to be reversed: A +B = B +A for addition; AB = BA (for scalar multiplication)
Transitive -- if A ≅ B and B ≅ C, then A ≅ C.
The property which is illustrated by the given statement is Symmetric property.
What is Reflexive property?Reflexive property states that for any number, c, the number is equal to itself.
Or in case of expressions, a + b = a + b.
Symmetric property states that, for any numbers m and n,
If m = n then n = m.
Transitive property states that, for any numbers m, n and o,
If m = n and n = o, then m = o.
Commutative property is for operation of numbers.
a + b = b + c
Given statement is If, ΔHXA ≅ ΔRGI, then ΔRGI ≅ ΔHXA.
This is symmetric statement.
Hence the correct option is D.

The top of a rectangular table has an area of 11 square feet. It has a length that is 3.5 feet more than the width. Find the dimensions of the table top.
The length of the table is ____ feet and the width of the table is ____ feet.
Step-by-step explanation:
If we let the width be w, then the length is w+3.5.
This means that w(w+3.5)=11
w^2 + 3.5w - 11 = 0
2w^2 + 7w - 22 = 0 (multiply both sides by 2)
(2w+11)(w-2)=0
w = -11/2 or w = 2 (disregard w = -11/2 as distance is positive)
This means that w=2, and thus the length is 2+3.5=5.5

Answer:
42 cm
Step-by-step explanation:
So, the dimensions of the square are 6*6, so we can find the area of that easily. 6*6 is 36. Now, we have to find the area of the triangle. Since 6 of the 8 cm across were used for the square, we only have 2 cm left to work with. The height of the triangle is 6. The formula to find the area of a triangle is 1/2(b)h. That would mean 1/2*2, which is 1, and then 1*6, which is 6. Finally, we add the areas of both shapes, which is 6 and 36, and we get 42.

A -4

no
-- 9
Answer:
x = - 43.5
Step-by-step explanation:
Step 1 : Simplify the given equation.
(8x - 20) - 16 = 10x + 51
8x - 20 - 16 = 10x + 51
8x - 36 = 10x + 51
Step 2 : Add/Subtract the alphabetical terms and numerical terms separately.
8x - 36 = 10x + 51
Step 3 : Add 36 on both sides.
8x = 10x + 51 + 36
8x = 10x + 87
Step 4 : Subtract 10x on both sides.
8x - 10x = 87
- 2x = 87
Step 5 : Divide - 2 on both sides.
x = 87/-2
x = - 87/2 (answer in terms of fraction)
x = - 43.5 (answer in terms of decimal)
Hence,
The value of x is - 43.5
