jane will run less than 32 miles this week. So far she has run 19 miles. what are the possible numbers of additional miles she will run ?use t for the number of additional miles she will run.
Answer:
Jane will run more than 30 miles this week, as thus far she ran 22.
Step-by-step explanation:
X + 22>30
X>8
She runs more than 8 miles.
Answer:
Well, it depends.
Step-by-step explanation:
In the problem, it doesn't specify if the miles she runs is a positive integer or not, but I will assume that it is.
There are number of miles: 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, and 31.
So t = 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, and 31
A rectangular prism has a length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm. A similar prism has a length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm. The dimensions of the smaller prism are each multiplied by what factor to produce the corresponding dimensions of the larger prism? 3 4 4 5
Answer: 3.5
Step-by-step explanation:
Given: Dimensions of larger prism = length of 4.2 cm, a width of 5.8 cm, and a height of 9.6 cm.
Dimensions of smaller prism = length of 14.7 cm, a width of 20.3 cm, and a height of 33.6 cm.
Scale factor = [tex]\dfrac{\text{Size of image}}{\text{Size of original figure}}[/tex]
Since, smaller figure is the original figure and the bigger one is the image.
So, scale factor = [tex]\dfrac{14.7}{4.2}=3.5[/tex] [Taking lengths
Hence, the factor to produce the corresponding dimensions of the larger prism = 3.5

Answer:
12 and 93.
Step-by-step explanation:
Let the grandsons age be x then Mr. Roger's age = 8x - 3.
Five years ago the grandson's age was x-5 and Mr Rogers was 8x - 8 years old , so:
8x - 8 - (x - 5) = 81
8x - 8 - x + 5 = 81
7x = 81 + 8 - 5 = 84
x = 12.
So the grandson is 12 and Mt Rogers is 8*12 - 3 = 93.

Answer:
The correct answer is:
[tex]+6x^{2}\\-9y^2[/tex]
Step-by-step explanation:
We are given the term:
[tex]3x^{2} +5y^{2} [\text{ \ }] +3 [\text{ \ }] +4y^{2} +6 = 9x^{2} -y^{2} +9[/tex]
We have to fill in to the empty spaces such that the above equation gets satisfied.
First of all, let us simplify the LHS (Left Hand Side):
[tex]3x^{2} +5y^{2} [\text{ \ }] +3 [\text{ \ }] +4y^{2} +6\\\Rightarrow 3x^{2} +5y^{2} +4y^{2} [\text{ \ }] [\text{ \ }] +6 +3\\\Rightarrow 3x^{2} +9y^{2} [\text{ \ }] [\text{ \ }] +9[/tex]
Now, let us equate the LHS and RHS (Right Hand Side):
[tex]\Rightarrow 3x^{2} +9y^{2} [\text{ \ }] [\text{ \ }] +9 = 9x^{2} -y^{2} +9[/tex]
Equating the coefficients of [tex]x^{2}\ and\ y^{2}[/tex] in LHS and RHS:
One box will have value = [tex]9x^{2} -3x^{2} =+6x^{2}[/tex]
Other box will have value = [tex]-y^{2} -9y^{2} =-10y^{2}[/tex]
The correct answer is:
[tex]+6x^{2}\\-9y^2[/tex]
So, if we fill the boxes with above values, the expression will be simplified as given.

Which statement about the graph are true
Answer:
None of the above
Step-by-step explanation:
the x coordinate tells us the duration, and the y-coordinate tells us the total cost of a phone call. The y coordinate of point aA represents the total cost of an 8 minutes phone call. not 8 phone calls. point a tells us that the cost is $2 for an 8-minute phone call, so the cost per minute is 2/8=$0.25, not $0.3.

The area of a circle is 81pi in.squared. What is the circumference, in inches? Express your answer in terms of pi
Answer:
18π
Step-by-step explanation:
the area of a circle is :
A= r²*π where r is the radius
here r² =81⇒ r= 9
the circumference of a circle is :
P= 2*r*π
P= 18π
Answer:
18 pi inches
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
81 pi = pi r^2
Divide by pi
81 = r^2
Take the square root of each side
sqrt(81) = sqrt (r^2)
9 = r
We want the circumference
C = 2 * pi * r
C = 2 * pi * 9
C = 18 pi

frnds pls help me
I want answer with full process pls help me
pls frnds do it fast pls help me
Answer:
Original number is 52.
Step-by-step explanation:
1) Two digit number xy,
it can be written as 10x + y.
2) The sum of the digits of a two-digit number is 7.
x + y = 7
3) The digits are interchanged the reversed number is yx,
the new number can be written as 10y + x.
4) The original number is 10x + y, so the tens digit of the original number is x.
5) Five times the tens digit of the original number is 5*x.
6) The reversed number is five times the tens digit of the original number:
10y + x = 5*x
7) We have system of two equations
x + y = 7 ----> x = 7 - y
10y + x = 5*x ---> 10y - 4x = 0
10y - 4x = 0
10y - 4(7 - y) =0
10y - 28 + 4y = 0
14y = 28
y = 2
x = 7 - y = 7 - 2 = 5
x = 5
Original number is 52.
New number 25.
Check:
Original number is 52, the tens digit is 5.
The reversed number (25) is five times the tens digit of the original number find the original number .
25 = 5*5 True

What is the weight (in grams) of a liquid that exactly fills a 465 milliliter container if the density of the liquid is 0.982grams over milliliter? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
Answer: 456.63 grams
Step-by-step explanation:
First, we know that we have 465 mL of a liquid. Secondly, we know each mL of the liquid = 0.982 grams. Thus, we can simply multiply 465*0.982 to get 456.63.
Hope it helps <3
The weight in grams of the liquid in a container is required.
The weight in grams of the liquid in the container is 456.63 grams.

A ladder is 8m long. It leans against a wall with one end on the ground 6m from the wall. How far up the wall does the ladder reach?
Step-by-step explanation:
Use pythagoras theorem
a^2=b^2+c^2
a^2=64+36
a=10m
The length up to the wall of the ladder will be around 5.2915.
What is Pythagoras theorem?The Pythagoras theorem is a theorem used to find out any length of a right-angle triangle.
Pythogoroous theorem is
Hypotenuse² = base² + perpendicular²
Given that a ladder leans against a wall so the ladder will act like a hypotenuse.
Let 6m be the base then we have to find the perpendicular.
Hypotenuse² = base² + perpendicular²
perpendicular² = Hypotaneous² - base²
perpendicular = [tex]\sqrt{ (Hypotenuse)^2 - (base)^2}[/tex]
Given hypotenuse is 8m and the base is 6m.
perpendicular² = 8² - 6²
perpendicular² = 28
perpendicular = √(28) = 5.2915 hence this much be far up the wall does the ladder reach.

Answer:
$2,459.21
Step-by-step explanation:
(see attached for reference)
recall that the formula for compound interest is:
A = P [ 1 + (r/n)^ (nt) ]
where,
A = Final amount ( we are asked to find this)
P = principal amount = given as $2,340
r = Annual Interest Rate = given as 5% = 0.05
n = number of times compounded in a year = 4 (compounded quarterly)
t= time = 1 year
Substituting the values into the equation,
A = P [ 1 + (r/n)^ (nt) ]
A = 2,340 [ 1 + (0.05/4)^ (4·1) ]
A = $2,459.21

At a DBE lecture of 100 students, there are 29 women and 23 men. Out of these students, 4 are teachers and 24 are either men or teachers. Find the number of women teachers attending the lecture.
Answer:
We operate the principle of sets to solve the problem. We are given the number of women to be 28 and men to be 23. The intersection will be while the union of both sets will be 24. To calculate the number of women teachers attending the lecture we first sum up the number of women and men and subtract from the intersection of both sets which gives us 3. Therefore, the number of teachers that are men are 3 while the number of women teachers are 1.
Step by step explaination:
Given the following, Let the set for men be represented by MM, that of women be represented by WW and that of teachers represented by TT.
Therefore, number of men i.e n(MM)= 23,
number of women i.e n(WW)= 29
number of teachers i.e n(TT)=4
number of men or teachers i.e n(MM U TT)= 24
Therefore, we have:
n(MM U TT)=n(MM) + n(TT) - n(MM n TT)
Therefore:
n(MM n TT)=n(MM) + n(TT) -n(MM U TT)
n(MM n TT)= 23+ 4 - 24 = 3
There fore number of men that are teachers are n(MM n TT)= 3 .
Therefore, from the number of teachers n(TT)=4
the number of teachers that are men are 3 while the number of women teachers are 1.
The diagonal of a square is x units. What is the area of the square in terms of x? One-half x squared square units x squared square units 2x square units One-half x square units
Answer:
[tex]\frac{x^2}{2}[/tex] square units [one-half x squared square units]
Step-by-step explanation:
As shown in the diagram attached to this response,
Since a square has all sides equal, let the sides of the square be each of a units.
The area, A, of the square = a x a = a²
i.e
A = a² --------------(i)
Now,
The diagonal is x units such that applying Pythagoras rule gives;
x² = a² + a²
x² = 2a²
a² = [tex]\frac{x^2}{2}[/tex] ----------------(ii)
Substitute the value of a² in equation (ii) into equation (i) to get;
A = [tex]\frac{x^2}{2}[/tex]
Therefore, the area of the square is [tex]\frac{x^2}{2}[/tex] square units

Answer:
So for the table , .3 + .1 + .25 + .35= 1.
and 10 green pins. read my explanation please cause i worked a lot on this.
Step-by-step explanation:
So first we add the probability of purple and gray getting picked.
.35 + .25= .6
And we know that the probability of green is 3 times yellow.
So. yellow can be x. and the equation would look like this.
3x + x +.6= 1
x equals .1, because 3x + x or 3(.1) + .1= .4
So, .3 + .1 + .25 + .35= 1.
This should be enough info to complete the table. Now b.)
So we know 14 purple pins... and the probability of that is .35
so if 14 = .35 what equals .25?
(I'm going to convert these decimals into percents for problem b until we get the answer, and then i'll make it back to a decimal form)
Okay, so
14= 35%
and that means .4 equals 1% or .01 probability
so now we times .4 to 25% to find out how many green pins are there.
.4 * 25= 10
So there are 10 green pins.

Answer:
Area of shaded part = 41.09733550
Perimeter of shaded part = 35.82011867
Step-by-step explanation:
Area of shaded part = ((πr^2) 4) - (bh ÷ 2)
Area of shaded part = ((π(12)^2) ÷ 4) - ((12)(12) ÷ 2)
Area of shaded part = (452.3893421 ÷ 4) - (144 ÷ 2)
Area of shaded part = (113.0973355) - (72)
Area of shaded part = 41.09733550
Perimeter of shadedpart:
AC = √a^2 + b^2
AC = √12^2 + 12^2
AC = √144 + 144
AC = √288
AC = 16.97056275
Perimeter of whole circle ÷ 4:
C=2πr
C=2π(12)
C=75.39822369
C ÷ 4 = 75.39822369 ÷ 4
C ÷ 4 = 18.84955592
Perimeter of shaded part:
18.84955592 + 16.97056275 = 35.82011867

Sylvia, John, and Peter invested their savings in a bank. The ratio of the investment of Sylvia’s to John's is 1: 3 and that of John’s to Peter’s is 4: 5.
What is the investment ratio of Sylvia : John : Peter ?
Answer:
The ratio is 4:12:15.
Step-by-step explanation:
we need to make the first ratio (Sylvia's to John's) comparable to second one (John's to Peter's). Since John is in both ratios, we use his number to make it the same. 3 and 4 can both be multiplied into 12. So, multiply the first ratio by 4 and the second by 3.
[tex](1:3) * 4 = 4:12\\(4:5) * 3 = 12:15[/tex]
Put it together, and you get 4:12:15.
Hope it helps :P
