Answer:
Ans(1) 167 (rounded off)
ans(2) 32 (rounded off)
Step-by-step explanation:
1. Pgs read in 12 mins= 40
Pgs read in 1 min= 40/12 =10/3
Pgs read in 50 mins= 10/3 ×50= 166.6
So, when rounded off, Susan can read 167 pgs in 50 mins./ (ans)
2. 2 inches distance= 7 miles
1 inch distance= 7/2 miles
9 inches distance= 7/2 × 9= 31.5
so, when rounded off, the cities are 36 miles apart in real life/ (ans)

StartFraction 800 divided by 8 Over 35 divided by 8 EndFraction = StartFraction 100 Over 4.375 EndFraction StartFraction 100 divided by 8 Over 800 divided by 8 EndFraction = StartFraction 12.5 Over 100 EndFraction StartFraction 35 times 8 Over 800 times 8 EndFraction = StartFraction 280 Over 6400 EndFraction StartFraction 35 times 8 Over 100 times 8 EndFraction = StartFraction 280 Over 800 EndFraction
Answer:
0.35(800)=x
x=number of tickets sold in advance
Step-by-step explanation:
Answer:
Divide 35÷100 which equals 0.35 then multiply 0.35×800 which equals 280 so the answer is 280 so the equation is 0.35×800=280.

A) what is the simplified product of seven-fourths divided by eight-fifths as an improper fraction
B) what is this number as a mixed number
Answer:
A)First were going to put our numbers in perspective.
[tex]\frac{7}{4}[/tex] ÷ [tex]\frac{8}{5}[/tex]
But to find the improper fraction, we have to cross multiply these numbers.
[tex]\frac{7}{4}[/tex] × [tex]\frac{8}{5}[/tex]
7 x 5 = 35.
4 x 8 = 32.
Now we have our improper fraction is [tex]\frac{35}{32}[/tex]
B)To turn our improper fraction into a mixed number, we will use division.
We know that the 32 can only go into 35 one time. We also know that the bottom number always stays the same. So our equation will look somewhat like this.
[tex]1\frac{?}{32}[/tex]
Now to fine the top number we will have to subtract 35 from 32 because we already know that 32 can go into 35 one time, so 35 - 32 = 3. So are mixed number will look like this.
[tex]1\frac{3}{32}[/tex]
This is our answer!
Answer:
7/4 ÷ 8/5
A. First, we need to do the reciprocal of 8/5.
7/4 x 5/8 = 35/32
B. Now, we need to convert it into a mixed number. Divide 35 by 32. 32 goes into 35 one time. 35 - 32 = 3, so remainder 3. We use 1 as the whole number since 32 goes into 35 one time. We use the remainder 3 as the numerator, and 32 as the denominator.
1 3/32

Rewrite 24.5 as a mixed number in lowest terms.
Rewrite 0.85 as a fraction in lowest terms.
Answer:
49/2, 17/20
Step-by-step explanation:
24.5=245/10=245÷5/10÷5=49/2
0.85=85/100=85÷5/100÷5=17/20
Answer:
Mixed numbers
a) 24 1/2
b) 85/100 = 17/20
Step-by-step explanation:
a) as they asked mixed number we only have to create a fraction for the decimal 0.5 = 1/2 and rewrite 24 1/2 = 24.5
If the question asked for lowest terms 24/5 then 24.5% = 245/1000 = 49/200
b) rewrite 0.85 as a fraction in lowest terms
0.85 = 85% = 85/100 = 17/20

m = (y2-y1)/(x2-x1) = (-12--16)/(6-2) = (-12+16)/4 = 1
E.

m = (y2-y1)/(x2-x1) = (-17--19)/(6-2) = (-17+19)/4 = 1
The greatest unit rate is the largest slope

From an 18-pound cut of meat, Mr. Rand cuts off steaks weighting 1 pound 15 ounces, 3 1/8 pounds, and 4 1/2 pounds. He divides up the rest into 9-ounces patties and sells them at 3 for $3.12. How much money does he receive for the patties?
Answer is in the picture
The amount of money received by him will be $15.60.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division
The amount will be calculated as follows:-
The cut off amount = 18 - ( 1(15/16) -3(1/8)-4(1/2) = 8(7/16)
Now 16 ounces make a pound so divide by 16 we get:-
(135/16) ÷ ( 9 / 16 ) = ( 135/16 ) x ( 16 / 9 ) = 15
Dividing 15 by 3 we get 5 packs of 3 patties for $3.12
So amount = 3.12 x 5 = $15.60
Therefore the amount of money received by him will be $15.60.

Answer: 10 inches
Step-by-step explanation:
If the two triangles are similar, that means their sides are proportional to each other.
JK = 15JL = 15 + 6 = 21JM = 14The proportion would look like this:
[tex]\frac{JK}{JL} =\frac{JN}{JM}\\[/tex]
Substitute in the values:
[tex]\frac{15}{21} =\frac{JN}{14}[/tex]
Cross-multiply and solve for JN:
[tex]21*JN=15*14\\JN=\frac{15*14}{21} =\frac{210}{21} =10[/tex]
Answer:
10 inches
Step-by-step explanation:
JM=14<JL=21
And you know that JN=X<JK=15
You also know that JM=14>JN=x
KL=6 so NM=4
JM= (14) - NM (4)= 10

Step-by-step explanation:
We need to use the formula :-
2 (l + b) × h ---> For Lateral surface area
2(30+30) h = 7200
2×60×h = 7200
120 × h = 7200
h = 7200/120
h = 60 cm
Now, volume = l×b×h
= 30×30×60

find the first four terms and the tenth term
a) 3n^2
Step-by-step explanation:
3n^2
First term => n=1 => 3(1)^2 =>3
Second term => n=2 => 3(2)^2 =>3x4=12
Third term => n=3 => 3(3)^2 =>3x9=27
Fourth term => n=4 => 3(4)^2 =>3x16=48
Tenth term => n=10 => 3(1)^2 =>3x10=300
Answer:
{3, 12, 27, 48, 300}
Step-by-step explanation:
For the first four terms, n = {1, 2, 3, 4}. For the tenth, n = {10}.
Then, applying the formula a(n) = 3n^2 to n = {1, 2, 3, 4, 10}, we get:
{3(1)², 3(2)², 3(3)², 3(4)², 3(10)²} = {3, 12, 27, 48, 300}
