Weatherman Glenn Burns predicts there to be 4.25 inches of rain on Saturday. On Saturday, it actually rains 6.5 inches. How much percent error was Glenn Burns from being accurate?
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.

is 976. find the number.
Answer:
awd
Step-by-step explanation:
The given conditions can be satisfied by the numbers 16 and 61.
What is place value?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.

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
If the line has a positive slope then its direction will be to the rightIf the line has a negative slope then its direction will be to the leftThe y-intercept (0, b) is the the point of intersection between the line and the y-axis
If the line cuts the y-axis at a point above the x-axis, then b is positiveIf the line cuts the y-axis at a point down the x-axis, then b is negativeTo 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
Raju’s father’s age is 5 years more than three times Raju’s age. Find Raju’s age,
if his father is 44 years old. ( 13 years)
please help
Answer:
Step-by-step explanation:
In order to find the answer, let's work backwards to find the original. We have to do the opposite to get to the Raju's age. We will start with his fathers age. (44) Then we will subtract five from it so that it will be divisible by three.
44 - 5 = 39
Then we just have to divide by 3.
44/3 = 13
His age is 13 years old.
There were some people on a bus. Half of the people get off at the first stop and 11 people get on. Now there are 20 people on the bus. How many people were on the bus to begin with?
Answer:
18 people
Step-by-step explanation:
18/2=9
9+11=20
Answer:
18.
Step-by-step explanation:
this is because in order to find out how many were on the bus, you simply do 20 - 11 = 9. Than you must multiply 9 by 2 which equals 18. That gives you your answer.

A triangle has an area of 12 square units and a height of 8 units. Find its base.
Answer:
3
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!!!
The lengths of the sides of a triangle are 7. and 10. If the length of the longest side of a similar triangle is 25. what is the length of the shortest side of this triangle?
Answer: 17.5

7:10 = x:25
times both sides by 25
25(7/10) =x
than solve for x
X = 25 × (7/10)
X = 17.5

48 divided by what equals eight
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

Harvey flew south 300 miles. He changed planes and then flew east 500 miles. If he travels a straight path back home, how many miles will he fly? Round to the nearest mile.
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.

Help Asap !Solve For X In The Diagram.
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
