Let the number of marbles Stevie has = x.

Given Freddie has twice as many marbles as Stevie

Number of marbles Freddie has = 2x.

Given Danny has 5 more marbles than Freddie .

Number of marbles Danny has = 2x+5.

In total they have 55 marbles

x+2x+2x+5=55

Adding like terms :

5x+5=55

Subtracting 5 both sides

5x=50

Dividing both sides by 5

x=10

Number of marbles Danny has = 2x+5=2(10)+5=20+5=25

Evaluate each expression if A=Z, B=5, X=4, and N=10. what is the answer for [a+8 (b-2)]^2÷4
nalin [4]

Hi!

<h3>Put in the values. </h3>

[z+8(5-2)]^2/4

<h3>Now use PEMDAS to solve. </h3>
  • Parentheses - Subtraction

[z+8*3]^2/4

  • Parentheses - Multiplication

[z+24]^2/4

  • Exponents

z+576/4

  • Division

<u>z+144</u>

<h2>When you evaluate [a+8 (b-2)]^2÷4, you get z + 144</h2>

Hope this helps! :)

The angle of elevation from a buoy in the water to the top of a lighthouse is 68degrees. If a buoy is 300 ft from the base of th
Katen [24]

Answer:

The height of the lighthouse is 742.5\ ft

Step-by-step explanation:

Let

h -----> the height of the lighthouse

we know that

The tangent of angle of 68 degrees is equal to divide the height of the lighthouse by the horizontal distance from the buoy to the base of lighthouse

so

tan(68\°)=\frac{h}{300}

Solve for h

h=(300)tan(68\°)=742.5\ ft

Calculate the average (arithmetic mean) for the data set (rounded to the nearest tenth
Ugo [173]

The right answer is 19.9

Step-by-step explanation:

Given data set is;

(18, 23, 17, 25, 15, 18, 18, 16, 27, 25, 18, 19)

Sum of terms = 18+23+17+25+15+18+18+16+27+25+18+19 = 239

Number of terms in data set = 12

Average = \frac{Sum\ of\ terms}{Number\ of\ terms}

Average = \frac{239}{12}

Average = 19.91

The average of data set is 19.91

The right answer is 19.9
