Answer:

26.8?

Step-by-step explanation:

4/5 is .80

7+7 equals 14

14.80

6+6 equals 12

14+12 is 26.

26+.80 is 26.8

The answer is 6.6 inches

AREA OF TRIANGLE = 1/2 X BASE X HEIGHT

=> 39.6=12XH/2

=> 39.6X2=12XH

=> 79.2 = 12XH

=> 79.2/12= H

=> 6.6

Solution:

Given:

Area of triangle formula: 1/2 x Base x Altitude

Substitute the area and the base:

Simplify the LHS:

Divide 6 both sides:

Answer:

1. 9

2. 25

3. No (Explanation below)

Step-by-step explanation:

1. Original PT Formula is c=√a²+b²

BUT you're looking for the leg so you now have the formula of a=√c²-b² *c being the hypotenuse

a= √ 15² - 12²

a= √ 225 - 144

a= √81

a= 9

2. 16 + 9 = 25

* you're not looking for an angle therefore you are most likely looking for the length of the side. Simply add the AD and DC together to get the answer. If you were looking for an angle it'll be 180°.

3. NO because a right angle is an angle of exactly 90°, whether it be at a corner of a square/rectangle, a triangle, or where two perpendicular lines intersect. Angle ABC is an obtuse angle as it measures more than 90°

Answer:

emma: 6 toys, sally: 13 toys, james: 23 toys

Step-by-step explanation:

if emma had x toys, sally would have (x-3) toys. and we know that if james had 6 more toys, he would have the same amount as both girls combined. so in this case in terms of x, james would have (x+x-3-6) toys, after simplification we get 2x-9 toys..

since we know that the three of them have 52  nerf toys as total, we can set up the equation:

x= number of toys emma has

2x-9+x+x-3=52  

         4x-12=52

               x=16

emma has 16 toys, and sally has (16-3)=13 toys. finally, james has (2*16-9)=23 toys. 16+13+23=52

Answer:

25.4

Step-by-step explanation:

If double of the number 'x' is 50.8, (2x=50.8)

Then the original number must be half of that value, (x=50.8/2)

50.8/2 = 25.4

we know the 100% or total is 50 hours, and walking was only 10 hours.

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 50&100\\ 10&x \end{array}\implies \cfrac{50}{10}=\cfrac{100}{x}\implies 5=\cfrac{100}{x}\implies 5x=100 \\\\\\ x=\cfrac{100}{5}\implies x=20[/tex]

Answer:

Step-by-step explanation:

x² - 24x + 5 = 0

x² - 24x = -5

Now divide the co efficient of x by 2 and square the quotient and add to both sides

24/2 = 12

12² = 144. Now add 144 to both sides of the equation.

x² - 24x + 144 = 5 + 144

x² - 24x  + 144 = 149

x² - 2*12*x + 12² = 149

(x  - 12)² = 149

Both sides take square root

x - 12  = ±√149

x = 12 ± √149

Answer:

The number in the middle is 60.

Step-by-step explanation:

The 2nd number = A

The 3rd number = B

The 4th number = C

Given:

(1) 130 + A + B = 300

(2) A + B + C = 200

(3) B + C + 10 = 100

Now, the work:

(2) can be modified to become A + B = 200 - C

Now, we can insert that into (1) and get the following;

130 + (200 - C) = 300

Open parentheses, simplify, you get C = 330 - 300.

C = 30

Using (3), we use above answer to get B + 30 + 10 = 100

Calculate, and get B = 100 - (30 + 10)

Simplify,

B = 60

There is your answer!

The inequality represent the situtation is 10.5 + x < 33.

In Algebra, inequality is a Mathematical statement that shows the relation between two expressions using the inequality symbol.

Given

Samuel is running a 3-mile race.

He would like to finish the race in under 33 minutes.

He has already run for 10.5 minutes.

Let, x be the number of the minutes left for the race.

The inequality represent the situtation is;

Answer: $973.75

Step-by-step explanation:

Price of T-shirts = $7.50

Price of Shorts = $9.00

Proce of Windbreakers = $12.25

35 T-shirts = 35 × $7.50 = $262.5

45 pairs of shorts = 45 × $9 = $405

25 windbreakers = 25 × $12.25 = $306.25

Total cost = $262.5 + $405 + $306.25

Answer:

Y= 200

Step-by-step explanation:

Just divide 30 by 0.15

Hope that helps!

Answer: y = 30/0.15

Step-by-step explanation:

First, convert 15% to a decimal by dividing by 100 to get 0.15. The word "of" in an equation means multiply, so the equation would be y*0.15 = 30. To isolate the variable you're trying to solve for, divide both sides by 0.15. The 0.15 on the left side of the equation cancels out, leaving you with a final equation of y = 30/0.15.

Step-by-step explanation:

the slope-intercept form of a line (= linear function) is

y = ax + b

"a" is the slope of the line and represents the ratio "y coordinate change / x coordinate change" when going from one point to another on the line.

"b" is the y-intercept (the y value when x = 0; in other words, the y value where the line intercepts the y axis).

so, for the slope, let's compare 2 points. and let's pick just the first 2.

(1, 8) to (2, 11).

x changes by +1 (from 1 to 2).

y changes by +3 (from 8 to 11).

so, the slope is +3/+1 = 3/1 = 3

and our equation looks like

y = 3x + b

to get b, we use one point. I pick the first one for the smallest numbers :

8 = 3×1 + b = 3 + b

5 = b

the full line equation is therefore

y = 3x + 5
