Answer:
Length of beads altogether in the necklace = 3.75 cm
Step-by-step explanation:
Length of the beads used in a necklace = [tex]\frac{5}{4}[/tex] cm
Number of beads used in the necklace = 3
Therefore, length of beads in the necklace = Length of each bead × Number of beads used
= [tex]\frac{5}{4}\times 3[/tex]
= [tex]\frac{15}{4}[/tex]
= 3.75 cm
Length of the beads altogether in the necklace = 3.75 cm
Which expression is equivalent to the expression below? Select all that apply.
-2/5(15 - 20d + 5c)
1. -30 + 40d - 10c
2. -6 + 8d - 2c
3. -2c + 8d - 6
4. 6 - 3d + 2c
Answer:
2 and 3
Step-by-step explanation:
To simplify this expression, you will need to use the distributive property.
Multiply -2/5 by 15 = - 6, -2/5 by -20d = 8d, and -2/5 by 5c = -2c.
you can switch these around to get -6 + 8d - 2c and -2c + 8d - 6.
Hope this helps :)

Nick poured 3/4 fluid ounce of vineger into each ten 1-fluid -ounce test tubes test tubes to use in an experiment for Science Night each circle represent 1 fluid ounce how many fluid ounces did nick pour
Answer:
7.5 fluid ounces
Step-by-step explanation:
Fraction of fluid ounce poured into each test tube
Number of test tubes filled = 10
The number of fluid ounces poured is the product of the amount poured into each test tube and the number of test tubes filled
Therefore, total amount poured :
(3/4 fluid ounces) * 10
0.75 * 10
= 7.5 fluid ounces

given f(x)=3(2-x)+5 what is the value of f(-5)?
Answer:
26
Step-by-step explanation:
given f(x)=3(2-x)+5 what is the value of f(-5)?
f(x)=3(2-(-5))+5 x minus a negative is a plus 2 - -5 = 2 +5
= 3(7) + 5

Answer:
[tex]x=44[/tex]
m∠1=118°
m∠2=62°
Step-by-step explanation:
Part A: They are supplementary angles, so
[tex]2x+30+62=180[/tex]
Simplify like terms,
[tex]2x+92=180[/tex]
We subtract 92,
[tex]2x=88[/tex]
Divide by 2,
[tex]x=44[/tex]
Part B:
[tex]m[/tex]∠[tex]1=2x+30[/tex] because ∠2 is vertical to 2x+30.
Plug in 44 for x,
[tex]m[/tex]∠[tex]1=2(44)+30[/tex]
Simplify,
[tex]m[/tex]∠[tex]1=118[/tex]
[tex]m[/tex]∠[tex]2=62[/tex]° because it is a vertical angle to the 62° angle.
Answer:
Solution given:
2x+30+62=180°[linear pair]
2x=180-92°
x=88/2=44°
Now,
<1=2x+30=2×44+30=118°[vertically opposite angle]
<2=62°[vertically opposite angle]
[vertically opposite angle]

Which of the following is the correct input-output table for the function? Y=6x+5
Answer:
The answer is table b.
Step-by-step explanation:
To solve this question, you can mentally calculate each value of each table, until you come to a wrong one. When you do, move on. To give an example:
Table a:
x input value: 1
y output value: 12
y true output value: 11
I did this by substituting the value of x in the equation given, so:
y = 6(1) + 5 = 11
Simply do this in your mind for each value, and you'll get your answer if every value in the table is correct!

NOT TO THE PEOPLE WHO JUST WANT MY POINTS!
Answer:
Its A
Step-by-step explanation:
To determine whether x and y have a proportional relationship, see if the line through these points passes through the origin (0, 0). The points are on a line that passes through the origin. So, x and y have a proportional relationship.
Hope this helps, and please mark brainliest.

Answer:
D. 74⁻⁶ (74^-6)
Step-by-step explanation:
Looking at the expression, I remember the following: 1 over an exponent (as a fraction) is the same thing as a negative exponent. None of these answers involve an exponent except for D (although A does involve a negative number). So D, which is 74⁻⁶, is the answer here.

-3x2 - 16x + 12
-3x2 - 16x + 12 =
Answer: −(3x−2)(x+6)
Step-by-step explanation:
We know it's factored because...
−(3x−2)(x+6)
If we multiply, then we get what we started with.
-3x * x = -3x^2
2 * x = 2x
-3x * 6 = -18x
2 * 6 = 12
-3x^2 - 18x + 2x + 12
-3x^2 - 16x + 12

During halftime of a football game, a slingshot launches T-shirts at the crowd. A T-shirt is launched from a height of 4 feet with an initial upward velocity of 80 feet per second. The T-shirt is caught 41 feet above the field. How long will it take the T-shirt to reach its maximum height? What is the maximum height? What is the range of the function that models the height of the T-shirt over time?
9514 1404 393
Answer:
time to max height: 2.5 seconds
max height: 104 ft
range of function: [4, 104]
Step-by-step explanation:
The equation for ballistic motion is ...
h(t) = -16t^2 +v0·t +h0 . . . . where v0 is the initial upward speed and h0 is the initial height
For the given parameters, the height function is ...
h(t) = -16t^2 +80t +4
The time for maximum height is ...
-b/(2a) = -80/(2(-16)) = 2.5 . . . seconds
The maximum height is ...
h(2.5) = (-16·2.5 +80)(2.5) +4 = 104 . . . feet
The range of the function is from the minimum height (at launch) to the maximum height:
4 ft ≤ h(t) ≤ 104 ft.
