Answer:

  the prediction was about 35% too low

Step-by-step explanation:

We generally define percent error as the difference between a measurement and an actual value, as a fraction of the actual value. Here, the actual value is 6.5 inches, so we can compute the error to be ...

  (4.25 -6.5)/6.5 × 100% = -34.6%

Burns' prediction was about 35% too low.

Step-by-step explanation:

b= 2 [tex]\frac{A}{Hb}\\[/tex] =   2 · [tex]\frac{12}{8}[/tex] = 3

Answer:

base= 3

Step-by-step explanation:

You need to work backwards to solve this problem

A= 1/2bh

with the information given, the equation should look like this:

12= 1/2b8

To get rid of the fraction, you flip it, and you multiply both sides by that (1/2 fliped is 2)

so  2* 12= 1/2b8 *2

-----------------------------------------------------------------------------

** You can see that the 1/2 and the two cancel each other out. This is why:

1/2* 2/1= 2/2

2/2=1

1 * b8 is just b8

----------------------------------------------------------------------------

So now you have:

24= b8

you want to get b by itself, so you use inverse operations ( you divide both sides by 8)

24/8= b8/8

your final answer is 3=b

you can plug in 3 into the original equation to check your answer!!!

Answer:

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

Here C = 32π , thus

πd = 32π ( divide both sides by π )

d = 32

Thus a coin with diameter 32 mm should fit through a slot of 35 mm

Answer:

Step-by-step explanation:

The given conditions can be satisfied by the numbers 16 and 61.

The foundation of our entire number system is place value. In this approach, the value of a digit in a number is determined by where it appears in the number.

Given, The sum of the digits of two numbers is 7. The product the number and its reverse number are formed by Interchanging the digits is 976.

Let "xy" be the given two-digit number.

Thus,

x +y =7....(1)

and (10x+y)(10y + x) = 976

100xy + 10y² + 10x² + xy = 976

101xy + 10y² + 10x² = 976

From equation 1

707x - 101x² + 490 +10x² - 140x + 10x² = 976

-81x² + 567x = 486

x² - 7x + 6 = 0

Thus x = 1, 6

y = 6,1

Therefore, The number that satisfies the given conditions is 16 or 61.

let the distance of the trail be x

and let the time be t

given that franks average speed is 2 miles per hour

the distance covered by Frank is x-3

the time taken by Frank to cover the distance is

we know that speed=distance/time

Answer:

The graph of the system of equations solves the equation  [tex]\frac{1}{2}[/tex] x - 4 = -2x + 1 ⇒ D

Step-by-step explanation:

Let us revise some important notes about the slope and y-intercept of a line

The form of the linear equation is y = m x + b, where m is the slope and b is the y-intercept

The y-intercept (0, b) is the the point of intersection between the line and the y-axis

To solve our question without any calculation, let us find the direction of the slopes and their y-intercepts

∵ The direction of the blue line is to the left

→ That means m in the equation is negative

∴ Its slope is negative

∵ The line intersects the y-axis at point (0, 1)

→ That means b in the equation = 1

∴ The number in the equation is 2

→ Look at the answer we have only one answers have negative slope and

   y-intercept = 1 in the right hand side ⇒ D

∴ The equation of the blue line is represented by the left side -2x + 1

→ That means the equation of the red line is represented by the left side

∵ The direction of the red line is to the right

→ That means m in the equation is positive

∴ Its slope is positive

∵ The line intersects the y-axis at point (0, -4)

→ That means b in the equation = -4

∴ The number in the equation is -4

→ Only D has a positive slope and y-intercept = -4 in the left side

∴ The equation of the red line is represented by [tex]\frac{1}{2}[/tex] x - 4

The graph of the system of equations solves the equation  [tex]\frac{1}{2}[/tex] x - 4 = -2x + 1

Another way:

You can solve each equation to find the value of x, then substitute it in one side of the equation to find y , the values of x and y must be (2, -3) as the point of intersection of the two lines in the graph

Answer:

X = 5

Step-by-step explanation:

suppose that angle TSU is y so

23x+5+y = 180

23x+y = 175

now again in traingle TSU

55+14x-5+y = 180

x = 130-y /14

substitute the value of x in 1st equation

ans will be 5

Answer:

x = 6.111

Step-by-step explanation:

The supplement of <AST = 180 - (23x - 5) That supplement is inside the triangle.

Solution

Add the three angles together to get 180

180-(23x - 5) + 14x-5 + 55 = 180         Remove the brackets

180 - 23x + 5 + 14x - 5 + 55 = 180      Combine

-9x + 55 + 180 = 180                        Subtract 180 from both sides.

-9x + 55 = 0                                     Subtract 55 from both sides

-9x = - 55                                         Divide by -9

x = -55/-9

x = 6.111

Check

180 - (23*6.111 - 5) + 14*6.111 - 5 + 55= 180

180 - 140.555 + 5 + 85.555 -5  + 55 = 180

39.445 + 85.555 + 55 = 180

180 = 180

Answer:

583 miles

Step-by-step explanation:

Let's draw this out (see attachment).

The straight line path creates the hypotenuse of a right triangle with legs of lengths 300 and 500. So, we use the Pythagorean Theorem, which states that for a right triangle with legs a and b and hypotenuse c:

a² + b² = c²

Here, a = 300 and b = 500. Then:

300² + 500² = c²

90000 + 250000 = c²

340000 = c²

c = √340000 ≈ 583.1 ≈ 583 mi

Thus, the answer is 583 miles.

Answer:

6

Step-by-step explanation:

6 is the answer because 6 times 8 equals 48, so if you divide 48 by 8 then the quotient would equal 6.

The number 48 should be divided by 6 to equal eight is 48 ÷ 6 = 8

To find what number 48 should be divided by to equal eight, we can set up the division equation and solve for the unknown value.

Let's represent the unknown number by 'x':

48 ÷ x = 8

Now, to find the value of 'x,' we can isolate it by performing the inverse operation of division, which is multiplication. We can multiply both sides of the equation by 'x':

x * (48 ÷ x) = x * 8

On the left side, 'x' cancels out with the 'x' in the denominator, leaving us with:

48 = 8x

Next, we can solve for 'x' by dividing both sides by 8:

48 ÷ 8 = 8x ÷ 8

6 = x

Therefore, the number 48 should be divided by 6 to equal eight:

48 ÷ 6 = 8
