Steps:-

  • First rewrite
  • Then convert to fractions
  • Then divide both

\\ \rm\rightarrowtail 5:8::7;9

\\ \rm\rightarrowtail 5/8:7/9

\\ \rm\rightarrowtail \dfrac{5(9)}{8(9)}:\dfrac{7(8)}{9(8)}

\\ \rm\rightarrowtail \dfrac{45}{72}:\dfrac{56}{72}

\\ \rm\rightarrowtail \dfrac{45}{56}

Answer:

5/8 is smaller.

Step-by-step explanation:

A ratio is just a different type of fraction, a 5:8 ratio means 5/8 which is 0.625. A 7:9 ratio equals 7/9 which is 0.777777

Then to compare them you see which is smaller or bigger.

0.77777  is bigger than 0.625 so we know that 0.77777777 which was the 7:9 ratio is the bigger one.

The sum of Cathy's and Tony's ages is 65. Eight years ago, Cathy's age was 2/5 of Tony's age. How old are they now?
Viktor [21]
Let
x------> Cathy's<span> ages
</span>y------> Tony's ages

we know that
x+y=65-----> x=65-y-----> equation 1
y-8=(2/5)*(x-8)-----> equation 2

substitute equation 1 in equation 2
y-8=(2/5)*(65-y-8)---> y-8=22.8-0.4y----> y+0.4y=22.8+8
1.4y=30.8-----> y=22
x=65-y-----> x=65-22----> x=43

the answer is
Cathy's ages is 43 years 
Tony's ages is 22 years

Find the area of the sector of a circle with radius 2 inches formed by a central angle of 4.3 radians: (in square inches)
aleksandr82 [10.1K]

Answer:

8.6 in²

Step-by-step explanation:

The area of the entire circle is A = πr², or A = π(2 in)².

This corresponds to a central angle of 2π radians, or 6.28 radians.

The area of the sector described above is just a certain fraction of that:

4.3 rad

-------------- * Area of circle = 0.685(4 * 3.14) = 8.6 in²

6.28 rad

If a math problem asks you about how much something is for division , will the problem make you estimate?
postnew [5]

Answer:

Yes

I hope this answers your question!

Step-by-step explanation:

How do you estimate a division problem?

You can use multiplication to check your division answer this way.

1) Do the division problem.

2) Multiply the quotient times the divisor.

3) If there is a remainder, add it to the multiplication product.

4) Compare this answer to the dividend. They should be the same number (630 = 630).

A dolphin jumped up out of the water and back into the water in a parabolic path. (H) height (t) seconds . H=-8(t-0.5)^2+2 . How
tigry1 [53]

Answer:

4 seconds

Step-by-step explanation:

using the vertex formula of a quadratic,

a(x-h)^{2} + k, where (h,k) is the vertex

h = -8(t-0.5)^{2}+2    h is height and t is time in seconds

the vertex (maximum height) of the dolphin is (h,k) or (0.5, 2)  

Height of 1/2

time of 2 seconds

it will take 2 additional seconds to reach the water again.

this can also be solved using quadratic equation, but since it was already set up in vertex form, i'd use that.
