Answer:

w = -4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Equality Properties

Step-by-step explanation:

Step 1: Define equation

-5 - 3w = 7

Step 2: Solve for w

Add 5 to both sides: -3w = 12
Divide -3 on both sides: w = -4

Step 3: Check

Plug in w to verify it's a solution.

Substitute: -5 - 3(-4) = 7
Multiply: -5 + 12 = 7
Add: 7 = 7

And we have our final answer!

2. Pam is making fruit baskets. She has 30 apples and 24 bananas.

Digiron [165]

Answer:

Six

Step-by-step explanation:

$\dfrac{\text{apples}}{\text{bananas}} =\dfrac{30}{24}$

Find the greatest common factor of each number.

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30

Factors of 24 = 1, 2, 3, 4, 6, 8, 12, 24

The greatest common factor of 30 and 24 is 6.

Jane can make six fruit baskets if she divides the fruit evenly among them.

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining Bismuth-210 transforms i

Luden [163]

Answer:

Approximately 76.5 mg.

Step-by-step explanation:

Given,

The initial quantity of the Bismuth-210, P = 233 mg,

Also, the rate of decay per day, r = 13 %

Thus, the quantity of the Bismuth-210 after 8 days would be,

$A=P(1-\frac{r}{100})^8$

$=233(1-\frac{13}{100})^8$

$=233(1-0.13)^8$

$=233(0.87)^8$

$=76.4733194697$

$\approx 76.5\text{ mg}$

Those 2 questions I need help with . find sec θ and tanθ

Zielflug [23.3K]

STEP - BY - STEP EXPLANATION

What to find?

The the value of secθ.

Given:

(4, 3)

⇒(x, y) = (4, 3)

Step 1

Draw a sketch.

Step 2

Substitute the values into the trig. ratio formula below.

$tan\theta=\frac{opposite}{adjacent}$

From the sketch above, opposite = 3 and adjacent = 4

$tan\theta=\frac{3}{4}$

Step 3

Find the value of the hypotenuse side using Pythagoras theorem.

let h be the hypotenuse side.

$\begin{gathered} h^2=4^2+3^2 \\ \\ =16+9 \\ \\ =25 \\ \\ h=5 \end{gathered}$

Hence, hypotenuse = 5

Step 4

Substitute the values into the formula below:

$\begin{gathered} cos\theta=\frac{adjacent}{hypotenuse} \\ \\ =\frac{4}{5} \end{gathered}$

But,

$sec\theta=\frac{1}{cos\theta}=\frac{1}{\frac{4}{5}}=\frac{5}{4}$

ANSWER

secθ= 5/4

tanθ=3/4
