There are 144 square inches in 1 square foot. How many square inches are in 2.5 square feet?
Answer:
360 square inches
Step-by-step explanation:
There are 360 square inches in 2.5 square feet.
To find out how many square inches are in 2.5 square feet, we need to multiply the number of square feet by the conversion factor.
Given that there are 144 square inches in 1 square foot, we can set up a proportion to solve for the number of square inches in 2.5 square feet:
1 square foot = 144 square inches
2.5 square feet = x square inches
Setting up the proportion:
1 square foot / 144 square inches = 2.5 square feet / x square inches
Cross-multiplying the proportions:
(1 square foot) x square inches = 144 square inches (2.5 square feet)
Simplifying the equation:
x square inches = 144 square inches (2.5 square feet)
Multiplying the values:
x square inches = 360 square inches
Therefore, there are 360 square inches in 2.5 square feet.

point 1 and -2 lies in the dash quadrant
Given:
The point is (1,-2).
To find:
The quadrant in which the point (1,-2) lies.
Solution:
We know that,
In first quadrant, both coordinates are positive, i.e., (x,y).
In second quadrant, x coordinate is negative but the y-coordinate is positive, i.e., (-x,y).
In third quadrant, both coordinates are negative, i.e., (-x,-y).
In fourth quadrant, x coordinate is positive but the y-coordinate is negative, i.e., (x,-y).
Where, x and y are two non-negative values.
In the given point (1,-2) the x coordinate is positive but the y-coordinate is negative.
Therefore, the point (1,-2) lies in fourth quadrant.

It is Marcie's first turn to roll. Which ratio shows the theoretical probability that she will not land on a star space? 1/6 1/3 1/2 2/3
Answer:
[tex]P(Not\ Star) =\frac{2}{3}[/tex]
Step-by-step explanation:
Given
See attachment
Required
Theoretical probability that a roll will not land on a star
From the attachment, we have:
[tex]n = 12[/tex] --- Total space
[tex]Star = 4[/tex]
So, the theoretical probability that a roll will land on a star is:
[tex]P(Star) = \frac{n(Star)}{n}[/tex]
[tex]P(Star) = \frac{4}{12}[/tex]
[tex]P(Star) = \frac{1}{3}[/tex]
Using the complement rule, the probability that it will not land on a star is:
[tex]P(Not\ Star) = 1 - P(Star)[/tex]
[tex]P(Not\ Star) = 1 - \frac{1}{3}[/tex]
Take LCM
[tex]P(Not\ Star) =\frac{3-1}{3}[/tex]
[tex]P(Not\ Star) =\frac{2}{3}[/tex]

Answer:
17,000m
or 7 km
Step-by-step explanation:
distance covered in 4 days = total distance x 2 x 4 days
convert the total distance to meters
(1000m x 2) + 125 = 2125m
total distance = 2125 x 2 x 4 = 17,000m or 7km

Answer:
4026
Step-by-step explanation:
Remember PEMDAS:
P - parenthesis
E - exponents
MD - Multiplication and Division (Left to Right)
AS - Addition and Subtraction (Left to Right)
------------------------
Start off by doing the parenthesis (7.1 x 10-5)
We must perform multiplication first so 7.1 x 10 is 71. From there you subtract 5 so 71 - 5 is 66!
So far we have: 66(6.7 x 10-6)
But we aren't done yet!
You must solve (6.7 x 10-6)
Same goes here, multiplication is done first so we would do 6.7 x 10 which is 67. Next, 67-6 which is 61.
We now have (66)(61)
When there is no sign of multiplication or division and the numbers are next to each other like this, you perform multiplication. So, 66x61 is 4026.
Thus, the answer is 4026!

Erica babysits for 4 1/2 hours and is paid $27 . If the people she babysits for have $31.50 to pay her, how long can they stay out?
Answer:
5.25 hours or 5 1/4 hours
Step-by-step explanation:
According to the scenario, calculation of given data are as follows,
Total time = 4 1/2 hours or 270 mins
Total payment = $27
First we calculate the time for $1, then
So, $27 = 270 mins
$1 = 270 ÷ 27 = 10 mins
Now, we can calculate total time in $31.50 by using following formula,
Total time in $31.50 = 10 mins × 31.50
= 315 mins
= 5.25 hours or 5 1/4 hours
Last year the schools newspaper so if full page ad for $16.50 each of H half page is $9.60 each day school they plan to increase the cost of 8 x 50% which expressions represent the total amount the school newspaper will earn from selling the same number of four and half page ad this year
Question isn't well formatted, however. From what can be gathered form the question :
Options are given
Answer:
4(1.5 * 16.50) + (1.5 * 9.60)
$113.40
Step-by-step explanation:
Last year:
Cost of full page ad = $16.50
Cost of half page ad = $9.60
50% increase in ad price this year :
Price, this year :
Full page = 1.50 * 16. 50 = $24.75
Half page = 1.50 * $9.60 = $14.4
Expression :
4(1.5 * 16.50) + (1.5 * 9.60)
Cost of a 4 and 1/2 page ad :
Full page = 4 * $24.75 = $99
Half page = 1 * $14.4 = $14.40
Total cost = $(99 + 14.40) = $113.40
[tex] \bigstar \: \underline{ \underline{ \tt{Question}}} : [/tex] In the given figure , M and N are the centres of two intersecting circles. Prove that :
i. PQ [tex] \perp[/tex] MN
ii. PR = RQ
~Thanks in advance! <3
Answer:
See Below.
Step-by-step explanation:
We are given two intersecting circles with centers M and N.
And we want to prove that: I) PQ ⊥ MN and that II) PR = RQ.
Since MP and MQ are radii of the same circle:
[tex]MP\cong MQ[/tex]
Likewise, since NP and NQ are radii of the same circle:
[tex]NP\cong NQ[/tex]
And by the Reflexive Property:
[tex]PQ\cong PQ[/tex]
Therefore, by SSS Congruence:
[tex]\Delta MPN\cong \Delta MQN[/tex]
By CPCTC:
[tex]\displaystyle \angle PMN\cong \angle QMN[/tex]
And by the Reflexive Property:
[tex]MR\cong MR[/tex]
And since they are the radii of the same circle:
[tex]MP\cong MQ[/tex]
Therefore, by SAS Congruence:
[tex]\Delta MPR\cong \Delta MQR[/tex]
Therefore, by CPCTC:
[tex]PR\cong RQ[/tex]
Note that PQ is a chord in Circle M.
Therefore:
[tex]\text{Segment $MN$ bisects chord $PQ$}[/tex]
In a circle, a segment that passes through the center of the circle that is perpendicular to a chord also bisects the chord.
And conversely, a segment that passes through the center of a circle that bisects a chord in the circle is also perpendicular to the chord.
So:
[tex]\displaystyle PQ\perp MN[/tex]
Answer:
Step-by-step explanation:
First step is to prove triangle MPN ad MQN are congruent.
MP=MQ, radius of circle M
NP=NQ, radius of circle N
we have two S in SAS and for A, we need to prove angle MPN = MQN
consider triangle QMP, it is isosceles so angle MPQ = MQP
consider triangle QNP; it is isosceles so angle QPN = PQN
combining the two above
angle MPN = MPQ+QPN = MQP+PQN = MQN
By SAS, triangle MPN and MQN are congruent
By symmetry, MN is perpendicular to PQ
It also disects PQ so PR = RQ

While on an 8.0 h trip, a car traveled for 3.5 h at an average speed of 90 km/h before stopping for 1.0 h. The car then traveled for 2.0 h at an average speed of 80.0 km/h For the last 1.5 h, the car traveled at an average speed of only 70.0 km/h. What was the average speed of the car for the entire 8.0 h trip?
Answer:
72.5 km/h
Step-by-step explanation:
Multiply the km/h by how many hours your going at that speed/total number of hours on trip.
(90x(3.5/8))+(80x(2/8))+(70x(1.5/8))
39.375+20.5+13.125
72.5km/h

Cross multiplication: Write your 2(or more) equivilent fractions, and write your variable as x or any other letter. If your variable is in the numerator, take the denominator and multiply it with the other fraction's numerator and divide your answer with the denominator of the other fraction. If x is in the denominator, switch your variable with the other fractions numerator and solve the same way you would if the variable was in the numerator-(sorry if I made it to complex, but the idea is really simple:)

A baseball bat that originally sold for $65 is on sale at a 15% discount. Which single gift card amount would cover the complete cost of the discounted bat? Select all that apply.
A
$10
B
$15
C
$50
D
$60
E
$80
Answer:
A
$10
Step-by-step explanation:
15% of $65 is 9.75
so $10 would cover the given amount
We want to see which card can cover completely the cost of a bat after a discount is applied. We will see that the correct options are:
D and E.
The baseball bat is originally sold for $65.
It has a discount of a 15%, then the new price is given by:
P = $65*(1 - 15%/100%) = $65*(1 - 0.15) = $65*0.85 = $55.25
So the gift cards that cover the whole cost of the discounted bat are these ones with a value equal or larger than $55.25
The correct options are:
D: $60
E: $80
With these two you could pay the complete cost of the discounted bat.
