are these ratios equivalent? 45/75 and 3/5

Answers

Answer 1
Answer: Yes, 45/75 simplifies to 3/5
Answer 2
Yes, because if you multiply 45 and 5, it is 225. If you multiply 75 and 3, it is also 225. Just multiply right numerator with left denominator, then multiply left numerator with right denominator.

If the area of a circle is
7.7 cm2, what is the
circumference of the
circle? (I need a step-by-step answer for further understanding please!!)

Answers

Answer:

Since area =7.7

[tex]area = \frac{22}{7} {(r)}^{2} \\ {(r)}^{2} = 2.45 \\ r = 1.57[/tex]

Then the circumference is

[tex]c = 2pi\times r \\ = 2 \times 3.14 \times 1.57 \\ = 9.859[/tex]

solve for x.... please help

Answers

Answer:

x = 5

Step-by-step explanation:

Both angles add to 180, so by knowing that we can say...

16x - 5 + -5 + 22x = 180

Now simplify and solve

38x - 10 = 180

      38x = 190

          x = 5

Plss helpppp I need it now

Answers

The formula is
SA=x/360 multiplied by pi multiplied by the squared radius
So therefore you substitute the values you have into the equation so:
SA= 300/360 x pi x 13 squared (radius is half of diameter so half of 26 is 13)
Therefore the answer should be
442.440
442.4 to one decimal place

Maya has a sandbox that is 4 1/2 feet long, 3 feet wide, and 1/2 foot deep. How many cubic feet of sand does she need to fill the sandbox completely?

A. 13 and 1/2

B. 6 and 3/4

C. 5 and 1/4

D. 8

Answers

We need to find the area. So we multiply the dimensions.

3x1/2=1.5

1.5x4 1/2=6.75

Decimal was my go-to so we need to convert back to a fraction.

6.75= 6 3/4

So the answer is B.

सीमा रेखाको समीकरण 2x + 3y = 6 र हल समूहमा
बिन्दु (0,0) भएको असमानता पत्ता लगाउनुहोस् ।
Find the inequality whose boundary line is
2x+3y= 6 and the solution set contains (0,0).​

Answers

Given:

The boundary line of an inequality is:

[tex]2x+3y=6[/tex]

The solution set contains (0,0).

To find:

The inequality.

Solution:

The boundary line of an inequality is

[tex]2x+3y=6[/tex]

Since (0,0) is in the solution set, therefore (0,0) satisfies the required inequality.

Taking LHS, we get

[tex]LHS=2x+3y[/tex]

Substitute x=0 and y=0.

[tex]LHS=2(0)+3(0)[/tex]

[tex]LHS=0+0[/tex]

[tex]LHS=0[/tex]

The right hand side of the given equation is 6.

[tex]RHS=6[/tex]

We know that,

[tex]0<6[/tex]

[tex]LHS<RHS[/tex]

[tex]2x+3y<6[/tex]

The boundary line is not a dotted line, it means the points on the boundary line are also included in the solution set. So, the inequality sign must be [tex]\leq [/tex].

[tex]2x+3y\leq 6[/tex]

Therefore, the required inequality is [tex]2x+3y\leq 6[/tex].
