HELP ASAP !!!!!!) Write an expression that would represent 2 times a number increased by 5.
Answer:
y=2x+5
Step-by-step explanation:
Suppose a charity received a donation of 15.2 million. If this represents 34% of the charity's donated funds, what is the total amount of its donated funds?
Round your answer to the nearest million dollars.
Answer:
45 million
Step-by-step explanation:
Let [tex]x[/tex] be the total amount of its donated funds. We can set up the following equation:
[tex]0.34x=15.2\:[\text{million}][/tex]
Solving for [tex]x[/tex], we get:
[tex]x=\frac{15.2\:[\text{million}]}{0.34},\\x=44.7\:\text{million}\approx \boxed{45\:\text{million}}[/tex]
Answer:
45 million dollars (44.706...)
Step-by-step explanation:
15.2 ÷ 0.34 = 44.706
To check our answer:
44.706 × 0.34 = 15.2

Jamie has already recorded 6 baseball cards and 9 football cards based on these data what is most likely the number of baseball cards in the deck?
Answer:
3 baseball + 9 football 9+3 = 12
3 out of 12 were base ball
3/12=0.25

please help :( it doesnt make any sense
Please helppppppppppppppppppppppppppo
Answer:
The correct answer is choice D.
Step-by-step explanation:
Since the parabola opens sideways, that means the function will feature [tex]y^2[/tex] and not [tex]x^2[/tex], so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of [tex]y^2[/tex] is positive. Using all of this information, you'll find that the correct answer is D: [tex]x = \frac{1}{12} y^2[/tex].

F(x)= -3x2^-3x, f(-2)
Answer:
-6
Step-by-step explanation:
We know that the equation is f(x)=-3x^2-3x.
This means when we plug -2 in, the equation will be f(-2)=-3(-2)^2-3(-2). Simplify this to get -3(4)+6. Simplify this to get -12+6 which is equal to -6. Therefore, f(-2)=-6

2) Poe Tayto wants to
know how long it will take an investment of $1,000
to earn $500 in interest if the yearly interest rate is 4.75%. Please answer fast and show work I will mark you as brain
Answer:
It will take 8.73 years.
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $1,000
Future value (FV)= $1,500
Interest rate (i)= 4.75% compounded annually
To calculate the time required for the initial investment to reach the objective, we need to use the following formula:
n= ln(FV/PV) / ln(1+i)
n= ln(1,500/1,000) / (1.0475)
n= 8.73
It will take 8.73 years.

Use SOH-CAH-TOA to find the missing side. Step by step.
Answer:
[tex]180.49[/tex]
Step-by-step explanation:
SOH-CAH-TOA:
In right triangles only:
The sine of an angle is equal to its opposite side divided by the hypotenuse. (o/h)
The cosine of an angle is equal to its adjacent side divided by the hypotenuse. (a/h)
The tangent of an angle is equal to its opposite side divided by its adjacent side. (o/a)
Since we're given an angle, its opposite side, and its adjacent side, we'll use tangent to solve for [tex]x[/tex]:
[tex]\tan 14^{\circ}=\frac{45}{x},\\x=\frac{45}{\tan 14^{\circ}},\\x\approx \boxed{180.49}[/tex].

A.
9
B.
45
C.
53
D.
65
Answer:
B
Step-by-step explanation:
Substitute x = 11 into the expression
5(11 - 2)
= 5 × 9
= 45 → B
Answer:
45
Step-by-step explanation:
A function is given to us .And we need to find its value at x = 11. So on substituting x = 11 , we have ,
The given function :-
[tex]:\implies[/tex] f(x) = 5(x-2)
On putting x = 11 :-
[tex]:\implies[/tex] f(11) = 5 ( 11 - 2)
[tex]:\implies[/tex] f(11) = 5 × 9
[tex]:\implies[/tex] f(11) = 45
Hence the value at x = 11 is 45 .Rylee drew a blue line that was 6 2/7 long and a red line that was 3 4/7 long. How much longer was the blue line than the red line?
