Answer:
40
Step-by-step explanation:
First, we must know that ab is the same as:
a × b
Now, since a is given as 8, we can substitute a with 8. This is shown below:
ab = 8 × b
Similarly, b is given as 5. So, we can substitute b with 5:
ab = 8 × 5
With this, we can now evaluate ab as shown below:
ab = 8 × 5
= 40

Answer: C
Step-by-step explanation:
Answer:
B. SSA
Step-by-step explanation:
Since segments JK and RQ are parallel, they are similar by both extending at the same angle and both segments formed by the parallel lines being proportional segments.Since the lengths of segments KZ and ZR are given, they are similar because they are proportional.Since vertical angles are always equivalent by the Vertical Angles Theorem, angles JZK and RZQ are congruent.Because we have 2 sides with a non-included (not in-between the two sides) angle, the triangles are similar by SSA Similarity.
I hope this helps!
The diameter of a cylinder is 8cm and the height is 2. What is the Volume? (NOTE: V=r2h)
Step-by-step explanation:
diameter= 8
radius=diameter/2
=8/2
=4
height=2
Volume =r2h
=4*2*2
=16
therefore the volume of the cylinder is 16 cm^3

58. Graph the function y=x^2+3x-18. How many real roots does the function have?
59. In #58, what value or values of the roots satisfy the function (if any exist)
9514 1404 393
Answer:
58. 2 real roots; see attached for a graph
59. -6, 3
Step-by-step explanation:
58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.
__
59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.
The radius of a circle is 18 yards. What is the circle's area?
Use 3.14 for .
Solution:
We know that:
Radius: 18 yardsπr² = Area of circleπ = 3.14Finding the area of the circle:
(π)(r²) = Area of circle=> (3.14)(18²) = Area of circle=> (3.14)(324) = Area of circle=> Area of circle = 3.14 x 324 = 1017.36 yards²[tex] \large{|\underline{\mathbb{\red{G}\blue{I}\orange{V}\pink{E}\blue{N}\purple{}\green{ : }\red{}\blue{}\orange{-}}}}[/tex]
Radius = 18 yards[tex] \large{|\underline{\mathbb{\red{T}\blue{O }\orange{ \: }\pink{ F}\blue{I}\purple{N}\green{D }\red{ : }\blue{ - }\orange{-}}}}[/tex]
Area of circle[tex] \underbrace{\mathbb{CALCULATION}}[/tex]
[tex] \qquad \sf \dashrightarrow \: Area\:of \:circle = \pi {r}^{2} [/tex]
[tex] \qquad \sf \dashrightarrow \: Area\:of \:circle = 3.14 \times {18}^{2} [/tex]

Solve algebraically
Answer:
n < - 0.6
Step-by-step explanation:
- 4n + 0.3 > 2.7
- 4n > 2.7 - 0.3
- 4n > 2.4
[tex]\frac{-4n}{-4}[/tex] < [tex]\frac{2.4}{-4}[/tex]
n < - 0.6
n ∈ ( - ∞ , - 0.6 )
-4n+0.3 > 2.7
-4n+0.3 -3.2 > 2.7-3.2 (Subtract 0.3 from both sides)
-4n > 2.7 - 0.3
-4n > 2.4
-4n/-4 > 2.4/-4 (Divide both sides by -4)
n > -0.6

A minor league baseball pitcher threw 18 strikes in his first 40 pitches for a strike percentage of 45%. He wants to raise this percentage to 60% by throwing a certain number of strikes in a row. To model this, he thought of the rational expression x+18x+40. What does x represent in this expression?
Answer:
The total number of strikes the pitcher will throw throughout the game.
Step-by-step explanation:
A.The number of consecutive strikes the pitcher must throw to raise his percentage to 60%.
B. The total number of strikes the pitcher will throw throughout the game.
C.The total number of balls the pitcher will throw throughout the game.
D. The number of balls that the pitcher has already thrown.
Given expression:
x+18x+40
In the expression, x represent the total number of strikes the pitcher will throw throughout the game.
The correct answer is A. The total number of strikes the pitcher will throw throughout the game.

16. Rihanna is the founder and CEO of Fenty Beauty on the release day of her new product,
Flyliner Longwear Liquid Eyeliner, she sold 400 eyeliners
and averaged 50 eyeliner sales
per day after that.
Which equation models the number of Flyliner Eyeliners, f, did Rihanna sell after d days.
A. f = 400 + 50d
B. f = 50 + 400d
C. d = 50 + 400f
D. d = 400 + 50f
Answer:
A. f = 400 + 50d
Step-by-step explanation:
First, let's understand each quantity/variable.
d: The variable, d, represents the number of days.f: f represents the total amount of eyeliners sold after each day.400 eyelines sold: This means that Rihanna sold 400 eyeliners on the first day of the release of her liquid eyeliner. This is known as the y-intercept.50 eyeliner sales per day: This means that after her first day, Rihanna sold 50 eyeliners each day. This can be represented as 50d.Now that we understand these variables, we can conclude that the equation would be A. f = 400 + 50d because to find the total, we have to add the 400 eyeliners sold at the beginning to the 50 eyeliner sales per day.
Have a lovely rest of your day/night, and good luck with your assignments! ♡
Is this angle supplementary or congruent? Please help.
Answer:
supplementary
Step-by-step explanation:
we have,
3x+15+2x=180
=> 5x +15 = 180
=> 5x = 180-15
=> 5x = 165
=> x = 165/5
=> x= 33
so, 3x+15 = 3*33+15
=> 99+15
=>114
2x = 2*33
=> 99
now we can check if these angles are supplementary
114 + 99 = 180
so, they are supplementary

the expression 53.7124×103 as a single number
Answer:
53712.4
Step-by-step explanation:
[tex]53.7124 * 10^{3}[/tex] This is the scientific notation, and since we do not have a negative exponent, we can assume that the decimal is going to move to the right, because when it's negative, the decimal will move to the left, making a smaller number.
So, when we move the decimal 3 times to the right, we find it sitting at 53712.4

Pls help me by answering these :(
Answer:
1) 21
2a) -23/30
2b) 6/55
Step-by-step explanation:
1) 3(x + 2) + 5x + 7
expand the brackets:
= 3x + 6 + 5x + 7
collect like terms:
= 8x + 13
when x = 1, (just substitute 1 for x)
8(1) + 13
= 8 + 13
= 21
2a)
-9/10 + 2/15
put both fractions on the same denominator (often we can just multiply each denominator by the other one):
so -9/10 * 15/15
= -135/150
and 2/15 * 10/10
= 20/150
now they're both on the same denominator and we can add the numerators:
-135 + 20 = -115
so our answer is:
-115/150
which we can simplify to:
-23/30
2b)
3/11*2/5
Multiplying fractions is very simple, as it doesn't require to have the same denominators. We can just multiply the numerators by each other and same for the denominators:
3*2 = 6
11*5 = 55
therefore, our answer is:
6/55
A)
3(x+2) + 5x + 7
3x + 6 + 5x + 7
3x + 5x + 6 + 7
put x = 1
3(1) + 5(1) + 6 + 7
3 + 5 + 6 + 7
21
B)
a)
[tex]\sf \rightarrow -\dfrac{9}{10} + \dfrac{2}{15}[/tex]
[tex]\sf \rightarrow -\dfrac{9(15)}{150} + \dfrac{2(10)}{150}[/tex]
[tex]\sf \rightarrow -\dfrac{135}{150} + \dfrac{20}{150}[/tex]
[tex]\sf \rightarrow \dfrac{-135+20}{150}[/tex]
[tex]\sf \rightarrow \dfrac{-115}{150}[/tex]
[tex]\sf \rightarrow \dfrac{-23}{30}[/tex]
b)
[tex]\sf \rightarrow \dfrac{3}{11} \ * \ \dfrac{2}{5}[/tex]
[tex]\sf \rightarrow \dfrac{3*2}{11 *5}[/tex]
[tex]\sf \rightarrow \dfrac{6}{55}[/tex]

Answer:
The distance between points R and S is [tex]\sqrt{ 29 }[/tex] units
Step-by-step explanation:
Coordinates of point R = (-1, 3)
Coordinates of point S = (4, 1)
Now, by distance formula:
[tex]d(R, S) = \sqrt{ \{4 -( - 1) \}^{2} + {(1 - 3)}^{2} } \\ \\ = \sqrt{ \{4 + 1 \}^{2} + {( - 2)}^{2} } \\ \\ = \sqrt{ \{5 \}^{2} + {( - 2)}^{2} } \\ \\ = \sqrt{ 25 + 4 } \\ \\ \implies \huge \orange{d(R, S) = \sqrt{ 29 } \: units}[/tex]
So, you are correct.
