What does the variable r represent in the equation 10r+4=8
Kryger [21]

Answer:

The value of variable r in the equation 10r+4=8 is \mathbf{r=0.4}

Step-by-step explanation:

We need to find the value of variable r in the equation 10r+4=8

Step 1: Write the equation

10r+4=8

Step 2: Subtract 4 on both sides

10r+4-4=8-4\\10r=4

Step 3: Divide both sides by 4

\frac{10r}{10}=\frac{4}{10}\\r=0.4

So, The value of variable r in the equation 10r+4=8 is \mathbf{r=0.4}

In ΔEFG, the measure of ∠G=90°, EF = 95 feet, and FG = 26 feet. Find the measure of ∠F to the nearest degree.
Firdavs [7]

Answer:

74.4°

Step-by-step explanation:

Given

  • ∠G=90° => ΔEFG is a right triangle
  • EF = 95 feet
  • FG = 26 feet

Use sine law to find ∠F

As we know:

Sin(GEF)/ GF = Sin(EGF)/EF

<=> Sin(GEF) / 26 = Sin(90)/95

<=>Sin(GEF) / 26 = 1/95

<=> Sin(GEF)  = 26/95

<=> ∠GEF ≈ 15.8°

=> ∠F = 180° - ∠G - ∠GEF

∠F = 180° - 90° - 15.8° = 74.4°

Hitman42 [59]

The amount each friend does pay is £9.75

<h3>How to calculate the pay of each friend using fractions and arithmetic operations?</h3>

We are going to find 5% of the total amount paid and divide it by the numbers of all the friends to determine the amount paid by each one of them.

From the given information:

  • The 5% of 130 = £6.5
  • Total amount paid = £130 + £6.5 = £136.5

Therefore, the cost of each friend is = \dfrac{136.5}{14}

The cost of each friend = £9.75
