Answer:
-43
Step-by-step explanation:
If a = 6.
B= -1 - 7a. a=6. 7a=42
B = -1 - 42 = -43
Toy rubber balls are packaged in a cylinder that holds 3 balls. The diameter of each ball is 4.5 cm. Find the volume of the cylinder. Use 3.14 for π. (Round to the nearest tenth as needed.)
Answer:
214.6 cm³Step-by-step explanation:
Volume formula:
V = πr²hGiven:
d = 4.5 cmh = 3*4.5 cmFind the volume:
V = 3.14*(4.5/2)²*(3*4.5) = 214.6 cm³ (rounded)
Answer :-
Total height = 4.5 × 4.5 × 4.5 = 91.125 cm
Radius = Diameter/2
Radius = 4.5/2 = 2.25 cm
Volume = πr²h
Volume = π (2.25)² × 91.125
Volume = π × 12.25 × 91.125
Volume = 1116.2 π cm³
soultion for 3x-5=2x+3-(x-4)
Answer:
6
Step-by-step explanation:
Initial problem:
3x - 5 = 2x + 3 - (x - 4)
First, distribute the minus sign to the parentheses:
3x - 5 = 2x + 3 - x + 4
Next, combine like terms:
3x - 5 = x + 7
Subtract x from both sides:
2x - 5 = 7
Add 5 to both sides:
2x = 12
Divide both sides by 2:
x = 6

Answer:45 ish
Step-by-step explanation:
What value of b makes the expression x^2 + bx + 4 a perfect square?
1
0
2
4
Answer:
b=4 makes the equation a perfect square.
Step-by-step explanation:
As long as you factorize out the equation, you'll get a result of (x+2)^2. This multiplied using foil gives you, x^2 + 2x + 4. Making it a perfect square. You could also have -2 = b which makes a perfect square, but that's not in the options.
Answer:
4
Step-by-step explanation:
The constant term 4 is obtained by
adding (half the coefficient of the x- term)²
4 = 2²
Then b = 4
x² + 4x + 4 = (x + 2)² ← a perfect square

Volume of a Cylinder
4 ft.
12 ft
Answer:
504 ft^3
Step-by-step explanation:
Ok, so we have the equation for the cylinder as well as the rectangular prism. Basically we're just going to find the volume of each of them separately and then add them together.
Let's start with the cylinder:
V(cylinder) = pi*r^2*h
pi = 3
d = 4ft
r = d/2 = 4/2 = 2ft
h = 12ft
V(cylinder) = (3)*(2^2)*(12)
V(cylinder) = 3*4*12
V(cylinder) = 144 ft^3
Now the rectangular prism:
V(rectangular prism) = l*w*h
l = 10ft
w = 6ft
h = 6ft
V(rectangular prism) = 10*6*6
V(rectangular prism) = 360 ft^3
Now we can add them together:
V(total) = 360 + 144
V(total) = 504 ft^3
Marketing company said 259 emails on Monday 431 emails on Tuesday and some emails on Wednesday if the company sent about like 1300 emails over three days about how many emails did the company send on Wednesday
Answer:
610
Step-by-step explanation:
Given:
259 emails on Monday431 emails on Tuesday? emails on WednesdayTotal emails = 1300Add:
259 + 431 = 690
Subtract:
1300 - 690 = 610
So, on Wednesday 610 emails were sent out.

If de=4x+10 Ef=2x-1 and df= 9x-15 find df
Step-by-step explanation:
Assuming that de + ef = df, we can create the expression:
(4x + 10) + (2x - 1) = 9x - 15
Combine like terms to get:
6x + 9 = 9x - 15
The rest is basic algebra after this point.
6x + 9 = 9x - 15
-6x +15 -6x +15
______________
24 = 3x ----> x = 8
Next, plug the x value into the df equation to find df.
df = 9(8) - 15
df = 72 - 15
df = 57
A fisherman can row upstream at 1 mph and downstream at 4 mph. He started rowing upstream until he got tired and then rowed downstream to his starting point. How far did the fisherman row off the entire trip took 5 hours?
He rowed for 4 miles
it took him 4 hours to get upstream which is 4 miles and since he can do 4 miles per hour down stream it only took him an hour to get back to the starting point which is 5 hours in total.

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]
Name the marked angle ( < KLI ) in 2 different ways[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
You can name the angle as < ILK too.Why? Well, to name an angle you only need to focus on keeping the vertex of the angle (the middle point where the angle gets formed) in the middle while naming. In this case the vertex is L. Then you can just shift the places of the 2 arms of the angle ( I & K ) & yea, then you'll get the name of the angle as < ILK.10.

answer choices are:
A. 46°
B. 67°
C. 115°
D. 134°
Answer:
134°
Step-by-step explanation:
∠BAC = ∠BCA because it is an isosceles triangle
∠XCA = ∠XAC . Congruent angles
∠XAC = 1/2(46) = 23° . because CE bisects ∠ C
∠XCA = 23°
180° - 23° - 23° = 134° . Sum of all angles in a triangle is 180°

6 (-2g - 1) = (13g + 2)
what is g?
Answer: g = -0.32
Step-by-step explanation:
Given
6 (-2g - 1) = (13g + 2)
Expand parentheses and apply the distributive property
6 · (-2g) - 6 · 1 = 13g + 2
-12g - 6 = 13g + 2
Add 12g on both sides
-12g - 6 + 12g = 13g + 2 + 12g
-6 = 25g + 2
Subtract 2 on both sides
-6 - 2 = 25g + 2 - 2
-8 = 25g
Divide 25 on both sides
-8 / 25= 25g / 25
