$\bf \cfrac{45}{63}\implies \cfrac{9\cdot 5}{9\cdot 7}\implies \cfrac{9}{9}\cdot \cfrac{5}{7}\implies 1\cdot \cfrac{5}{7}\implies \cfrac{5}{7}$

Answer: OPTION A.

Step-by-step explanation:

You have the folllowing fraction given in the problem:

$\frac{5}{7}$

To find an equal fraction, you must multiply the numerator and the denominator by the same number.

OPTION A. The product is obtained by multiplyin 5 by 9 and the produc 63 is obtained by multiplyin 7 by 9. Then, you obtain:

$\frac{5*9}{7*9}$ = $\frac{45}{63}$

The fraction of OPTION B is not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

The fraction of OPTION C is not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

The fraction of OPTION D is not not obtained by multiplying the numerator and the denominator of originl fraction by the same number.

A cable 20 feet long connects the top of a flagpole to a point on the ground that is 16 feet from the base of the pole. How tall

timurjin [86]

Think of it like a triangle.

The flagpole is vertical and is at 90° to the ground. This makes a right-angle to the ground, which is flat.

Since we have two sides of the triangle already, and they are in a ratio of ?? : 16 : 20 = ?? : 4 : 5, that means that because the triangle is a right-angled triangle, the third and last side must be 3 to complete the ratio! (This is called 'Pythagoras')

Since the other sides were divided by 4 to get the simple ratio, we must multiply 3 to get the actual ratio! 3 × 4 = 12 ft tall flagpole.

Ben and Josh went to the roof of their 40-foot tall high school to throw their math books off the edge.

krok68 [10]

Answer:

Josh's book lands first
Ben's lands about 0.648 seconds later

Step-by-step explanation:

Using the given equation for v=60 and s=40, the height of Ben's book is ...

h(t) = -16t² +60t +40

We want to find t when h(t) = 0, so we're looking for the solution to ....

0 = -16t² +60t +40

Using the quadratic formula, we find the positive value of t to be ...

t = (-60 -√(60² -4(-16)(40)))/(2(-16)) = (15 +√385)/8 ≈ 4.3277

Similarly, the height of Josh's book is ...

0 = -16t² +48t +40

t = (-48 -√(48² -4(-16)(40)))/(2(-16)) = (12 +√304)/8 ≈ 3.6794

The time before Josh's book lands is shorter by ...

4.3277 -3.6794 ≈ 0.6482 . . . . . seconds

Josh's book reaches the ground first, by about 0.648 seconds.

How to find the area of this figure

stiv31 [10]

Answer:

45 square units.

Step-by-step explanation:

Applying the pythagoras theorem:

Base of the bigger triangle = $\sqrt{15^2 - 9^2}$ = $\sqrt{144}$ = 12 units

Area of a triangle is given by $\frac{1}{2}$ × base × height

The area of the bigger triangle is $\frac{1}{2}$ × 12 × 9 = 54 square units.

The area of the smallest triangle is $\frac{1}{2}$ × (12 - 10) × 9 = 9 square units.

The area of the figure( required triangle) is 54 - 9 = 45 square units.

What happens to the volume of a square pyramid if the base dimensions remain the same, but the height is cut to one third of the

Nadya [2.5K]

The volume becomes 1/3 of the original. With a rectangular base, volume of a pyramid is V=(length*width*height)/3. Cutting the height to 1/3 of the original length will make the total volume 1/3 of the original volume.
