Answer:

64"

Step-by-step explanation:

Pythagoras theorem

√(80²-48²)

√4096

=64

Answer:

Width = 64"

Step-by-step explanation:

It forms a right angled triangle. We can use Pythagorean theorem to find the base of the triangle

Base² + altitude² = Hypotenuse²

base² + 48² = 80²

base² +  2304 = 6400

           base² = 6400 - 2304

            base² = 4096

           base = √4096

base =  64

Width = 64"

Answer:

62 degrees

Step-by-step explanation:

Cos ? = 25 / 54

25 / 54 = 0.4629

Cos-1 of 0.4629 is 62.4215

Round to the nearest degree

62.4215 = 62

Answer:

√24 because it's lies on between of√16 and√25.

The only square root that falls between 4 and 5 is √24.

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

We can estimate the value of each square root and see which one falls between 4 and 5:

The value of √10 is less than 4 because √10 is, 3.16

√14 is less than 4.5 because  √14 value is 3.76

√24  is greater than 4.5 because √24 value  is 4.89

√32  is greater than 5 because 5 x 5 = 25, and √32 is slightly smaller than 5.

Therefore, the only square root that falls between 4 and 5 is √24.

Answer:

Step-by-step explanation:

Use the equation x = -b/2a => x = -12/6 = -2.

Answer:

the third choice.  x>_-6

Step-by-step explanation:

1. When you have the square root of (x+6), it shifts the graph 6 units to the left.  

2.  So the x values would start and include -6 and continue growing to the right.

3. So the domain (x values) of the equation is x is greater than or equal to -6

Answer:

u can add or mutiply all them together

Answer:

40.6

Step-by-step explanation:

0.7(58)

Answer:

40.6

Step-by-step explanation:

When finding a percentage of something you have to turn the percentage into a decimal. You divide by 100 so 70/100 is equal to 0.70. Simply mutiply this by 58 so .7*58=40.6

70% of 58 = 40.6

Answer:

Part A:

y=70+10x

13 weeks

Step-by-step explanation:

200=70+10x

-70    -70

_______________

130=10x

x=13

Answer:

200-70= x

x/10=W

Step-by-step explanation:

$200 is the amount he wants save.

He already saved $70. (subtracting 70 from 200 gives me 130)

130 is what he still needs so if i divide that by 10 ( the amount hes putting in each week). this leaves me with 13. 13 is the amount of weeks left until he reaches his goal.

Answer:

∠x = 70°

Step-by-step explanation:

Given that PQ||BR

Line PQ and BR with transversal AC,

∠x + ∠ACR = 180°     {Co-interior angles}

⇒∠x + 110° = 180°       {From what I can see it looks like 110.}

⇒∠x = 180° - 110°

⇒∠x = 70°

a) We were told that relationship between the value of the car and its age is linear. This means that it can be represented with a linear equation such as

y = mx + c

y is the dependent variable and in this case, it is the value of the car, V

x is the independent variable and in this case, it is the age of the car, a

The above equation is the slope intercept form equation where

m represents slope

c represents y intercept

The formula for determining slope is expressed as:

m = (y2 - y1)/(x2 - x1)

We were told that a 5 year old car is worth 14000. This means that

When x1 = 5, y1 = 14000

Also, the same car is worth 11400 after 2 years. This means that the car is worth 11400 after 7 years. Thus,

when x2 = 7, y2 = 11400

Thus,

slope, m = (11400 - 14000)/(7 - 5) = - 2600/2

m = - 1300

We would find the y intercept, c by substituting m = - 1300, x = 5 and y = 14000 into the slope intercept equation. Thus,

14000 = - 1300 * 5 + c

14000 = - 6500 + c

c = 14000 + 6500

c = 20500

Thus, by substituting m = - 1300 and c = 20500 into the slope intercept equation, the linear equation representng this scenario is

y = - 1300x + 20500

By replacing with the given variables,

V = - 1300a + 20500

b) When the car was new, it means that a = 0. By substituting a = 0 into the equation, we have

V = - 1300 * 0 + 20500

V = 20500

The value of the car was $20500 when it was new

Answer:

B) P = 8x + 4

Step-by-step explanation:

Formula:

P= 2( l + w)

P = 2( x + 2 + 3x)

P = 2(4x + 2)

P = 8x + 4

Answer: -15 divided by 0.3 is the same as -15/3/10 but to solve we can do -15 times 10/3 witch is -150/3=-50

Step-by-step explanation:

Answer:

(X2+3)2

Step-by-step explanation:

First, you have to substitute in what f(x) equals for y since f(x) stands for y.

By doing this, the equation turns into (x2+3)2, because x2+3 is y, and 2 because the original equation way y2.

After you substitute, the answer is (x2+3)2.

189

Equation for surface area is 2bs +b squared ( b is base and a is side)

Step-by-step explanation:

2bs+b squared

2 * 7 * 10=140

B squared = 7 squared which is 49

140 + 49=189.
