Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter
How do you do 4 divided by 0.8 in place value
Answer:
5
Step-by-step explanation:
because that is the correct answer
4 divided by 0.8 is equal to 5.
To divide 4 by 0.8 using place value, you can follow these way
Convert the decimal divisor, 0.8, into a whole number by multiplying both the tip and the divisor by a power of 10.
Since there's only one decimal place in0.8, you can multiply both figures by 10 to exclude the decimal
0.4 x 10 = 40( multiplying the tip by 10)
0.8 x 10 = 8( multiplying the divisor by 10)
Now we've the division problem as 40 divided by 8.
Divide the converted tip by the converted divisor
= 40 ÷ 8
= 5
Thus, 4 divided by 0.8 is equal to 5.

2) Use the formula of triangular prism: (Base x height x length) ÷ 2
3) Use the formula of cylinder: π x [tex]radius^{2}[/tex] x height
--------------------------------------------------------------------------------------------------
1)
width = 5 cmheight = 9 cmlength = 23 cmwidth x height x length
= 5 x 9 x 23
= 1035

h =
Answer:
[tex]h = - 12[/tex]
Step-by-step explanation:
1) Add 1 to both sides.
[tex] \frac{h}{6} = - 3 + 1[/tex]
2) Simplify -3 + 1 to -2.
[tex] \frac{h}{6} = - 2[/tex]
3) Multiply both sides by 6.
[tex]h = - 2 \times 6[/tex]
4) Simplify 2 × 6 to 12.
[tex]h = - 12[/tex]
Therefor, the answer is h = -12.
Answer:
h = - 12
Step-by-step explanation:
Add 1 to both sides of the equation
ℎ/6 − 1 + 1 = − 3 + 1
Simplify
ℎ/6 = − 3 + 1
h/6 = -2
Multiply all terms by the same value to eliminate fraction denominators
6 ⋅ ℎ/6 = 6 ( − 2 )
Cancel multiplied terms that are in the denominator
ℎ = 6 ( − 2 )
Multiply the numbers
ℎ = − 12

An expression is shown.
1 3/7 divided by 1 1/3
What is the value of the expression as a mixed number?
Answer:
1 ¹⁄₁₄
Step-by-step explanation:
[Step 1] [convert mixed fractions to improper fractions]
1 3/7 divided by 1 1/3 →
a b/c = b + a(c) / c = (b + ac) / c.
3 + 1(7) / 7 divided by 1 + 1(3) / 3 →
10 / 7 divided by 4 / 3.
[Step 2] [flip the numerator and denominator(take the reciprocal) of the fraction you are dividing by and multiply]
10 / 7 divided by 4 / 3 →
a / b → b / a = 1 / (a / b) = (a / b) ^ -1.
10 / 7 multiplied by (3 / 4).
When you multiply 2 fractions, you multiply across. Numerator × Numerator / Denominator × Denominator.
a / b × c / d = (a × c) / (b × d).
10 / 7 multiplied by (3 / 4) →
10 / 7 × 3 / 4 →
(10 × 3) / (7 × 4) →
30 / 28.
[Reduce completely until the denominator or numerator is prime or can only be divided by one and itself to remain an integer]
30 / 28 →
15 / 14.
[Find the difference between the numerator and denominator and that will be the numerator of the mixed fraction or the remainder, the denominator will be the same denominator of the improper fraction and the whole part will be how many times the denominator can fit in the numerator of the improper fraction]
[Or you can do long division and you will add the quotient (top number above long division bar) and the remainder.]
a / b = (# times b fits into a) + (remainder / b).
15 / 14 = (# times 14 fits into 15) + (1 / 14).
15 / 14 = 1 + (1 / 14)
15 / 14 = 1 ¹⁄₁₄
