The answer is (A) 24

Step-by-step explanation:

we can convert the 80 and the 3/10 into fractions then we can find the least common denominator of 10 and 80, it is 80 so 3 times 8 its 24 so the fraction should be 24/80 and there is you answer.

what number must be added to 3 and 8 so that the ratio of the first number to the second number is equal to 3 :4​
Grace [21]
The answer is 12.
Steps
If that number is x
(3+x)/(8+x)=3/4
"Cross multply"
4(3+x)=3(8+x)
12+4x=24+3x
x=12
To check: add 12 to 3 and 8. 3+12=15 and 8+12=20. 15/20=3/4

Step-by-step explanation:

Firstly convert the diameter into cm

t480812.5cm³hus 3.5×100=350cm

Volume=

\frac{\pi {d}^{2} h}{4}

\frac{3.14 \times (350) {}^{2} \times 5 }{4}

=480812.5cm³

Answer:

The answer to your question is:  9.01 x 10⁸ ice cream cones

Step-by-step explanation:

Data

# of ice cream cones = 1700

5.3 x 10 ⁵ minutes ---------- 1 year

# of ice cream cones purchased in one year = ?

                              1700  cones ---------------------  1 min

                                 x                ----------------------  5.3 x 10 ⁵ minutes

             x = (5.3 x 10 ⁵)(1700)/1 = 901 000 000 ice cream cones

In scientific notation

                                   9.01 x 10⁸ ice cream cones

Please help, I dont know how to do this​
Mrrafil [7]

Answer:

\frac{y-2}{4}

Step-by-step explanation:

Let's start by factoring everything:

\dfrac{\frac{y^2+y}{y^2-2y}}{\frac{4y+4}{y^2-4y+4}}=

\dfrac{\frac{y(y+1)}{y(y-2)}}{\frac{4(y+1)}{(y-2)^2}}=

Now, you can cancel out some terms:

\dfrac{\frac{y+1}{y-2}}{\frac{4(y+1)}{(y-2)^2}}=

Now, when you divide a fraction by another fraction, that is the same as multiplying the first fraction by the reciprocal of the second one:

\frac{y+1}{y-2}\cdot \frac{(y-2)^2)}{4(y+1)}=

\frac{y-2}{4}

Hope this helps!

Answer:

a) 7/4 b) 15/2

Step-by-step explanation:

a) Scale Factor = Image / Object

Take the side of Triangle ABC that's BC Why? Because it corresponds with the Image Triangle ADE's DE

= 21/12 = 7/4

b) 7/4 = 10+ x / 10

Cross Multiply

= 4 ( 10 + x ) = 70

= 40 + 4x = 70

= 4x = 70-40

= 4x = 30

= 4x/4 = 30/4

x = 15/2
