Answer:
68,000,000
Step-by-step explanation:
Look at the hundred thousands place. If it's a 5 or higher you round up and if it's lower you round down. Since there is 4 in the hundred thousands place you round down. Everything to the right turns into a zero.
Answer:
She made 7 field goals
Step-by-step explanation:
With the data we can make 2 equations
1 x + 2 y= 26
x+y=19 and y=19-x
Where,
x= free throws
y=field goals
Replacing y in the first equation
1 x + 2 (19-x)= 26
1 x + 38-2x= 26
1 x - 2x= 26 - 38
- 1x= -12
x=12
y=19-12
y=7
Answer:
45 in, 30 in and 25 in
Step-by-step explanation:
Add the parts of the ratio : 9 + 6 + 5 = 20 parts
Divide the perimeter by 20 to find one part of the ratio.
= 5 ← 1 part of the ratio
9 parts = 9 × 5 = 45
6 parts = 6 × 5 = 30
5 parts = 5 × 5 = 25
45 inches, 30 inches and 25 inches are the measures of each side
Answer:
56
Step-by-step explanation:
Just substitute 7 for p in the expression 9p - 7: 9(7) - 7 = 56
Answer:
c = 42.5
Step-by-step explanation:
The legs of the triangle are a and b and the hypotenuse is c
Let a be the shorter leg
The hypotenuse is 5 more than the longest leg
c = b+5
The shortest leg is 20
a = 20
We can use the Pythagorean theorem
a^2 +b^2 = c^2
Substituting in what we know from above
20 ^2 + b^2 = (b+5)^2
FOIL (b+5)^2 = b^2 +5b+5b +25 = b^2+10b+25
400 + b^2 = b^2+10b+25
Subtract b^2 from both sides
400+b&2-b^2 = b^2 -b^2 +10b+25
400 = 10b+25
Subtract 25 from both sides
400-25 = 10b+25-25
375 = 10b
Divide by 10
375/10 = 10b/10
37.5 = b
But we want to find c
c=b+5
c = 37.5+5
c = 42.5
