Answer:

The base is 90 sq

Step-by-step explanation:

Formula for Area= 1/2*b*h

where b is unknown and area = 54sq

1/2 *b*12 = 54sq

12b = 54*2

12b /12 = 54*2/12

b = 9sq

Answer:

x = 44.8

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj/ hyp

cos 48 = 30/x

x cos 48 = 30

x = 30 / cos 48

x=44.83429

Rounding to the nearest tenth

x = 44.8

Answer:

156.7 mi

Step-by-step explanation:

Applying

Pythagoras theorem

a² = b²+c²............... Equation 1

Where c = distance to the earth horizon from point P

From the diagram in the question,

Given: a = (3959+3.1) mi = 3962.1 mi, b = 3959 mi

Substitute these values into equation 1

3962.1² = 3959²+c²

solve for c

15698236.41 = 15673681+c²

c² = 15698236.41-15673681

c² = 24555.41

c = √ 24555.41

c = 156.7 mi

Answer:

5

Step-by-step explanation:

5 ^ 1/3  * 25 ^ 1/3

Rewriting 25 and 5^2

5 ^ 1/3  * 5^2 ^ 1/3

We know that a^b^c = a^ (b*c)

5 ^ 1/3  * 5^ 2/3

We know a^b  * a^c = a^(b+c)

5^ ( 1/3 + 2/3)

5^1

5

Answer:

B

Step-by-step explanation:

Explanation:

The x coordinates are -4 and 14. They add up to -4+14 = 10. Then this cuts in half to get 10/2 = 5. This is the x coordinate of the midpoint.

We'll follow this same idea for the y coordinates as well.

10+0 = 10 which cuts in half to 10/2 = 5, and this is the y coordinate of the midpoint.

Therefore, the midpoint is (5,5).

Coincidentally, the x and y coordinates are the same for the midpoint (both are 5). This won't always happen.

Answer:

2 feet

Step-by-step explanation:

for area of a triangle it's (height times width) divided by 2, and 10 times 2 divided by 2 is 10

Answer:

Length of base of triangle = 2 feet

Step-by-step explanation:

Given:

Area of triangle = 10 square feet

Height of triangle = 10 feet

FInd

Length of base of triangle

Computation:

⇒ Area of triangle = (1/2)(Base)(Height)

⇒ 10 = (1/2)(Base)(10)

⇒ 10 = Base(5)

⇒ Length of base of triangle = 10 / 5

Length of base of triangle = 2 feet

The 2nd cage can have minimum 4 hamster

The 1st cage can have minimum 8 hamster

The fewest hamsters David can have are 15

A number system is defined as a system of writing to express numbers.

Given that David has 4 cages of hamsters.

The second cage has 1/2 as many hamsters as the first.

The third cage has 1/2 as many hamsters as the second.

The fourth cage has 1/2 as many hamsters as the third.

Let the first cage has n number of hamsters

the first cage has n/2 number of hamsters

the second cage has n/4 number of hamsters

the third cage has n/8 number of hamsters

the third cage has n/16 number of hamsters

4=n+n/2+n/4+n/8+n/16

n=15

Hence, the fewest hamsters David can have are 15

Answer:

8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

This is a special right triangle with angle measures 90-60-30 degrees

The side lengths are like the following :

The side length that sees 90 degrees is represented with x

The side length that sees 60 degrees is represented with x[tex]\sqrt{3}[/tex]

The side length that sees 30 degrees is represented with 2x

the side that sees 90 degrees is given as 16 so x = 8 and so  a = 8[tex]\sqrt{3}[/tex]

Answer:

5sqrt2

Step-by-step explanation:

Using the pythagorean theorem, we get 5^2+5^2=c^2. C is the diagonal here. 25+25=c^2, c^2=50. c=sqrt50. Simplifying it, we get the diagonal as 5sqrt2.

Answer:

ion even know

Let’s start with the easy part: half of the base is 3.

Therefore, 3 x h + 1 = 18

3 x h = 3h and 3 x 1 = 3

3h + 3 = 18

To solve these equations, you have to do the inverse. First you would need to minus 3:

3h = 15

3h is a simpler way of saying 3 x h, so the inverse would be a divide.

h = 5

Answer:

Hello the answer is 5x - y = 30!

Step-by-step explanation:

m = (0 (-5))/(6 - 3) = (0 + 5)/(3) = 5/3

y = mx + b

O = (5/3)(6) + b

O = (30/3) + b

O = 10 + b

-10 = b

3y = 5x - 30

3y + 30 = 5x

5x - 3y = 30

Answer:

Question 4:  [tex]y=\displaystyle -\frac{4}{5}x[/tex]

Question 5: [tex]y=-5x-3[/tex]

Step-by-step explanation:

Hi there!

Linear equations are typically organized in slope-intercept form: [tex]y=mx+b[/tex] where m is the slope of the line and b is the y-intercept (the y-coordinate of the point where the line crosses the y-axis).

Question 4

1) Determine the slope (m)

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex] where two points that pass through the line are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

In the graph, two easy-to-identify points on the line are (-5,4) and (5,-4). Plug these into the equation:

[tex]\displaystyle m=\frac{-4-4}{5-(-5)}\\\\\displaystyle m=\frac{-4-4}{5+5}\\\\\displaystyle m=\frac{-8}{10}\\\\\displaystyle m=-\frac{4}{5}[/tex]

Therefore, the slope of the line is [tex]\displaystyle -\frac{4}{5}[/tex]. Plug this into [tex]y=mx+b[/tex] as the slope (m):

[tex]y=\displaystyle -\frac{4}{5}x+b[/tex]

2) Determine the y-intercept (b)

On the graph, we can see that the line crosses the y-axis when y is 0. Therefore, the y-intercept (b) is 0. Plug this into [tex]y=\displaystyle -\frac{4}{5}x+b[/tex]:

[tex]y=\displaystyle -\frac{4}{5}x+0\\\\y=\displaystyle -\frac{4}{5}x[/tex]

Question 5

1) Determine the slope (m)

[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Two easy-to-identify points are (-1,2) and (0,-3). Plug these into the equation:

[tex]\displaystyle m=\frac{-3-2}{0-(-1)}\\\\\displaystyle m=\frac{-3-2}{0+1}\\\\\displaystyle m=\frac{-5}{1}\\\\m=-5[/tex]

Therefore, the slope is -5. Plug this into [tex]y=mx+b[/tex]:

[tex]y=-5x+b[/tex]

2) Determine the y-intercept (b)

On the graph, we can see that the line crosses the y-axis at the point (0,-3). The y-coordinate of this point is -3. Therefore, the y-intercept (b) is -3. Plug this into [tex]y=-5x+b[/tex]:

[tex]y=-5x+(-3)\\y=-5x-3[/tex]

Answer:

It's a square with four equal sides each side is 6cm. The angles at the four edges are all same have 90° between each two sides. You can calculate the area of the four triangles by using the formula 1/2 × hight × base. The hight will be 6 divided by 2 which is equal 3cm, and the base will be 6cm. So the area of each triangle is 1/2×3×6=9cm^2.
