The required inequality would be 99x + 84 ≤ 1,150. so the correct option is C.
What is a solution set to an inequality or an equation?If the equation or inequality contains variable terms, then there might be some values of those variables for which that equation or inequality might be true. Such values are called solution to that equation or inequality. Set of such values is called solution set to the considered equation or inequality.
Given;
The cost of the shirt she bought = $ 84,
And the cost of each watch she bought = $ 99,
Now Suppose she bought x watches,
So, the cost of x watches = 99x dollars,
Also, her total spending = 84 + 99x
Since she has a total budget of $1,150,
That is her spending can not be exceed $ 1,150, ( or spending must be less than or equal to $ 1150 )
⇒ 99x + 84 ≤ 1,150
Hence the required inequality would be 99x + 84 ≤ 1,150. so the correct option is C.

Which statement best describes a line in slope-intercept form when the coefficient of the x-term is positive
Answer:
The line will be going 'uphill' from left to right
Step-by-step explanation:
we know that
The equation of the line into slope intercept form is equal to
y=mx+b
where m is the slope
b is the y-intercept
If the coefficient of the x-term is positive
then
the slope is positive
therefore
If the values of x increases, the values of y increases
If the values of x decreases, the values of y decreases
The line will be going 'uphill' from left to right

Sue travels by bus or walks when she visits the shops. The probability that she catches the bus to the shops is 0.4. The probability she catches the bus from the shops is 0.7. Show the probability that Sue walks at one way is 0.72
Answer:
Proved,
P(A∪B)=0.72
Step-by-step explanation:
Sue travels by bus or walks when she visits the shops.
Probability( catch the bus to the shop ), P(A) = 0.4
Probability( catch the bus from the shop ), P(B) = 0.7
Both A and B are independent events.
Therefore,
P(A∩B) = 0.4×0.7
= 0.28
Probability Sue walks one way = 1 - P(A∩B)
= 1 - 0.28
= 0.72
Hence, the probability that Sue walks at one way is 0.72
The probability that Sue walks one way is 0.18, derived by subtracting the probability that Sue takes a bus one way (0.82) from 1.
Explanation:The question refers to the probability involving Sue's mode of transport to and from the shops. To show the probability that Sue walks one way, we need to first determine the probability that she takes a bus either to or from the shops, since taking a bus one way implies she walked the other way.
The probability that Sue takes a bus to the shops OR from the shops, but not both, can be calculated using the formula: P(A U B) = P(A) + P(B) - P(A ∩ B). In this case, A represents the probability Sue takes a bus to the shop (0.4) and B represents the probability she takes a bus from the shop (0.7). P(A ∩ B) is the probability she takes a bus both ways, which is 0.4 * 0.7 = 0.28.
Therefore, the probability she takes the bus one way is P(A U B) = 0.4 + 0.7 - 0.28 = 0.82.
Since Sue either takes a bus or walks, the sum of these two probabilities should be 1. Therefore, the probability Sue walks one way is 1 - the probability she takes the bus one way = 1 - 0.82 = 0.18, not 0.72 as suggested in the question.

Evaluate the expression when a=3 and b=4
[tex]2a^{2} +b=[/tex]
Answer:
The answer to this problem is 22.
Step-by-step explanation:
To solve this problem, we simply need to plug in the values given for a and b into the expression given and simplify.
We are given that a=3 and b=4, thus, these are the numbers we will plug in before we simplify.
2a^2 + b =
2(3)^2 + 4
Next, we should follow the rules of PEMDAS. This tells us that we should solve the parentheses first, but since there are no parentheses, we can move onto exponents.
If we simplify, we get:
2(9) + 4
Next, we should perform the multiplication.
18 + 4
Finally, we can add together the remaining terms.
18 + 4 = 22
Therefore, your answer is 22.
Hope this helps!

Answer:
The volume of the cylinder is 150.72 cm³ ⇒ last answer
The volume of the cone is 314 cm³ ⇒ 1st answer
The volume of the pyramid is 160 cm³ ⇒ 2nd answer
The volume of the pyramid is 48 cm³ ⇒ 3rd answer
Step-by-step explanation:
* Lets revise the volumes of some shapes
- The volume of the cylinder of radius r and height h is:
V = π r² h
- The volume of the cone of radius r and height h is:
V = 1/3 π r² h
- The volume of the pyramid is:
V = 1/3 × its base area × its height
* Lets solve the problem
# A cylinder with radius 4 cm and height 3 cm
∵ V = π r² h
∵ π = 3.14
∵ r = 4 cm , h = 3 cm
∴ v = 3.14 (4)² (3) = 150.72 cm³
* The volume of the cylinder is 150.72 cm³
# A cone with radius 5 cm and height 12 cm
∵ V = 1/3 π r² h
∵ π = 3.14
∵ r = 5 cm , h = 12 cm
∴ V = 1/3 (3.14) (5)² (12) = 314 cm³
* The volume of the cone is 314 cm³
# A pyramid with base area 16 cm² and height 30 cm
∵ V = 1/3 × its base area × its height
∵ The area of the base is 16 cm²
∵ The height = 30 cm
∴ V = 1/3 (16) (30) = 160 cm³
* The volume of the pyramid is 160 cm³
# A pyramid with square base of length 3 cm and height 16 cm
∵ V = 1/3 × its base area × its height
∵ The area of the square = s²
∵ The area of the base = 3² = 9 cm²
∵ The height = 16 cm
∴ V = 1/3 (9) (16) = 48 cm³
* The volume of the pyramid is 48 cm³
a right cylinder with radius 4 cm
and height 3 cm = 150.72 cu cm
a pyramid with base area
16 sq cm and height 30 cm = 160 cu cm
a pyramid with a square base of

Answer:
BD=AD-AB=6-4=2
Step-by-step explanation:
You have a line segment AD that measures 6 units
AB is part of it and it is 4 units
There is only one part left of AD and it is BD so you just find what's left of 6 if 4 is already spoken for.
For this case we have that the radius of the large circle is given by AD = 6, while the radius of the small circle is given by AB = 4. We want to know the length BD, that is, the difference of the radius of the big circle and the small one.
[tex]BD = AD-AB = 6-4 = 2[/tex]
So, [tex]BD = 2[/tex]

Lines g and h are parallel and m 1 = 45°
What is m 2 8?
Answer:
m<5 = 45 deg
Step-by-step explanation:
Since lines g and h are parallel, you have a transversal cutting parallel lines. Then, corresponding angles are congruent.
Angles 1 and 5 are corresponding angles, so they are congruent, and their measures are equal.
m<5 = m<1 = 45 deg.
Angles 5 and 8 are vertical angles, so they are congruent, and their measures are equal.
m<8 = m<5 = 45 deg

Answer:
The correct answer is third option
π(3)(5) + π3²

Points to remember
Surface area of cone = πrl + πr²
Where r is the radius of the cone and l is the slant height of cone
To find the correct answer
Here r = 6/2 = 3 in
l = 5 in
Surface area = πrl + πr²
= π(3)(5) + π3²

2. Invert the proper fraction and change division to multiplication
[tex]x = \dfrac{15}{2} \times \dfrac{4}{3}[/tex]
3. Multiply numerators and denominators

4. Divide the numerator and the denominator
[tex]x = 10[/tex]
The quotient is what you get after you invert the denominator in Step 2 and then multiply the two fractions in Step 3.

So let's solve, this first convert the mixed fraction into an improper fraction that is its ideal form to solve an equation
[tex]7\frac{1}{2} = \frac{15}{2}[/tex]
therefore,

Do the minimal of the two functions have the same x-value?
Which of the function has the greater minimum?
The given function F(x) = x^2-8x+7 has a minimum point of (4, -9). This is found by using the formula for the vertex of a quadratic function.
Explanation:This question seems to be incomplete as only one function, F(x) = x^2-8x+7, is provided. However, I can still help you find the minimum of this function. A quadratic function, such as this one, has a minimum or maximum at its vertex. The x-coordinate of the vertex (h) can be found using the formula h = -b/2a.
In this function, a = 1 and b = -8, so h = 8/2 = 4. So the minimum point of the function is at x = 4. To find the corresponding y value, we substitute x = 4 in our function. F(4) = 4^2-8*4+7 = -9. So the minimum point of F(x) = x^2-8x+7 is (4, -9).
