8z + 15 = -1 | z = ?

Mathematics
1 answer:
Fiesta28 [93]3 years ago
6 0

Answer:

z = -2

Step-by-step explanation:

Step 1: Write equation

8z + 15 = -1

Step 2: Solve for <em>z</em>

  1. Subtract 15 on both sides: 8z = -16
  2. Divide both sides by 8: z = -2

Step 3: Check

<em>Plug in z to verify it's a solution.</em>

8(-2) + 15 = -1

-16 + 15 = -1

-1 = -1

Anyone know how to do it
Morgarella [4.7K]

Answer:

Surface area of cube = 6x²

surface area of cube = surface area of sphere

it means that 6x²=4πr²

x²=

\frac{4\pi {r}^{2}  }{6}  =  \frac{4 \pi9}{6}  =  \frac{4\pi3}{2}  = 6\pi

x =   \sqrt{6\pi}

\sqrt{6\pi}  =  \sqrt{k\pi}

6\pi = \pi \: k

k = 6

Answer:

  1. FALSE
  2. TRUE
  3. TRUE

Step-by-step explanation:

<u>1.</u>

  • Non-standard units can be used to measure volume
  • Examples : m³, in³, cm³, mm³, L

<u>2.</u>

  • The volume of a rectangular prism can be found by multiplying the length, width, and height
  • <u>V = lwh</u>

<u />

<u>3.</u>

  • If there are smaller units, then naturally more of the units will be used
  • If there are larger units, then less of the units will be used

Find the exact value of secθ if cscθ=-4/3 and the terminal side of θ lies in Quadrant III.
Anton [14]
Quadrant is III so, sign would be negative for Sec.
Now, we know, csc = H / P
So, H = 4, P = 3
Calculate for B, 
B² = H² - P²
B² = 4² - 3²
B² = 16 - 9
B = √7

We know, sec Ф = H / B = 4 / √7
We can write it as: -4√7 / 7  [ -ve sign for 3rd quadrant ]

In short, Your Answer would be Option B

Hope this helps!

Five times the sum of 3 and twice some numbers is 70. What is the number?
Anna11 [10]
Let x represent some number
Sum of 3 and twice some number = 3 +2x
Five times the sum of 3 and twice some number: 5(3+2x)

5(3+2x)=70
15+10x=70
Subtract 15 from both sides to have 10x by itself
10x=55
Divide 10 on both sides to get x by itself
x=55/10
x=5.5

Hope this helped
