Answer:
It would be $12 overestimate
Step-by-step explanation:
$2.19 rounded to one significant figure would be $2.00
$2.00 multiplied by 6 would be $12
However since 19 cents is over $2, this means it's a definite overestimate

AB is a chord of a circle of radius 5cm the distance of AB from the centre is 3cm then AB is?
Answer:
8 cm
Step-by-step explanation:
We first want to draw a diagram with the given information.
I am unsure if the image shows below, or if it is an attachment.
We then see we have a right triangle. What is a theorem that is commonly associated with right triangles?
So we use the pythagorean theorem to find the missing leg of the triangle has a length of 4 cm. But how does this help us? Well, when finding the distance from the center of a circle to a chord, we always find the line that is perpendicular to the chord and divides it in half (and passes through the center), and find the length.
So, the leg of length 4 we just found? That's half of our answer.
Since 4 × 2 = 8, we know that the length of AB is 8 cm.
Eric is keeping track of rain water. On Monday it rained 1 3/4cm. On Tuesday it rained 2 1/8cm. How much more did it rain on Tuesday than on Monday
Answer:
It rained 3/8 cm more on Tuesday than Monday.
Step-by-step explanation:
What I first did is convert the fraction 3/4 into 6/8 (multiply both sides by two) so I could get a common numerator to solve the two fractions. Then, I gave one whole from the 2 wholes in 2 1/8 to 1/8 to make it easy to subtract with 6/8 (I wuldn't like to do 1/8-6-/8) and made it into 9/8. Then it's simple subtraction (oh yes and don't forget to turn the 2 into 1 since it lost a whole) and voila! 3/8 cm
A-b =56
A:b is equal to 9:2
Answer:
A = 72
B = 16
Step-by-step explanation:
Ratio problems can often be worked by considering them in terms of "ratio units." Here, the difference in ratio units is 9-2 = 7. The difference between the actual numbers is A -B = 56. This means each ratio unit stands for an actual number value of 56/7 = 8
Then the ratio of actual values is ...
A : B = (9·8) : (2·8) = 72 : 16
Check: These actual values of A and B have a difference of 72-16 = 56.
(A, B) = (72, 16)

Step-by-step explanation:
Using the y=mx+b format, we can define the slope as 1...
1) y=1x+b or y=x+b
The y-intercept ( aka b )
2) y=x+4

[tex]\text{Slope intercept form:}[/tex] [tex]\text{y = (m)x + (b)}[/tex] [tex]\text{[m = Slope; b = y-intercept]}[/tex]
To find the equation of the line, substitute the slope and the y-intercept in the slope intercept form formula.

Grams of butter : grams of flour
= 170 : 250
= 170 / 250
= 17 / 25

Mumble. The square root is something called "monotonic", which means that [tex]a > b \Leftrightarrow \sqrt a > \sqrt b[/tex]
A neat trick to solve this will be: go back from 17 till you find a perfect square, then add 1 to it:
In our case it's easy to do it, since the number before 17 is a perfect square already ([tex]16=4^2[/tex]), so we can pick it as the lower bound, and then add 1 to the base to find the next one ([tex]4+1= 5)[/tex]

Solve for X

6
2x – 18
U
4x - 29
PLEASE HELP!
Answer:
x = 15
Step-by-step explanation:
SV = ST + TU + UV , substitute values
4x - 29 = 13 + 6 + 2x - 18 , that is
4x - 29 = 2x + 1 ( subtract 2x from both sides )
2x - 29 = 1 ( add 29 to both sides )
2x = 30 ( divide both sides by 2 )
x = 15
The points S, T, U, and V are collinear points. Then the value of the variable x will be 15.
What are collinear points?If the points are in a line, then the points are collinear points.
Let A, B, C, and D are collinear point. Then the condition of the collinear will be
AB + BC + CD = AD
The line segment SV is given.
And the point T and U lies on the line segment SV.
The length of ST is 13, the length of TU is 6, the length of UV is 2x - 18, and the length of SV is 4x - 29.
It is clear that the points S, T, U, and V are collinear points.
ST + TU + UV = SV
13 + 6 + 2x - 18 = 4x - 29
2x + 1 = 4x - 29
2x = 30
x = 15
The value of the variable x will be 15.

what is x of the rectangle?
Answer:
x = 8
Step-by-step explanation:
Since this is a rectangle, we know that each corner's angle is 90 degrees. (The box thing at the bottom right shows this.)
Since the two angles that make up angle E sum up to 90, we can make an equation:
(9x - 6) + (2x + 8) = 90
11x + 2 = 90
11x = 88
x = 8

5 people build 3 huts in 21 days . Find the number of people that will build 6 huts in 15 days ?
3 huts are built by 5 people in 21 days.
So 1 hut is built by 5 people in 7 days.
That is to say, 1 hut requires 5*7 = 35 man-days.
Which means 6 huts need 6*35 = 210 man-days.
If the time available is 15 days, 6 huts will need 210 man-days/15 days = 14 people.
Answer = 14 people.
In class VIII, there are 140 students. The ratio of boys to girls is 4:3. a) Find number of girls. b) Find number of boys.
Answer:
A) 60 girls B)80 boys
Step-by-step explanation:
Pretend that the ratio is a fraction. If there are 4 boys for every 4 girls, than pretend that you add the 4 and the 3 together, thus giving you 7 as your denominator. Start with the girls, giving you a fraction of 3/7, multiply by 140, you get 60 as the number of girls. 140-60=80, giving you 80 boys.

H is 3 units above and 1 unit to the right of the origin. K is 1 unit above and 3 units to the right of the origin. And N is 0 units above and 2 units to the right of the origin.
Answer:
Point H is (1,3)
Step-by-step explanation:
The x co - ordinate lies to the right and the y co-ordinate lies above . We are given H is 3 units above and 1 unit to the right of the origin so the co-ordinates of H are ( 1,3).
As this particular order (x,y) is used to represent the the point it is called ordered pair.
The ordered pairs of the other points are
Point A is (4,5)
Point C is (5,4)
Point H is (1,3)
Point K is (3,1)
Point N is (2,0)

43.185.is the upper bound of 43.18 which is corrected to 2 decimal places.
What is upper bond?An element greater than or equal to all the elements in a given set
We need to find the upper bound of 43.18 cm correct to 2 decimal places
2 decimal place = 0.01
0.01 ÷ 2 = 0.005
So now add 43.18 and 0.005.
43.18 + 0.005 = 43.185.
