What ratio is equivalent to 80:88

Answer:

x = 24

Step-by-step explanation:

Here, The Right angled triangle is given

So, The sum of angles of right angled triangle is 180

Now,

2x + 42 + 90 = 180

2x + 132 = 180

2x = 180 - 132

2x = 48

x = 48/2

x = 24

2x + 42 + 90 = 180

2(24) + 42 + 90 = 180

48 + 42 + 90 = 180

180 = 180

Hence, L.H.S = R.H.S

There were 30 boys in Orchestra.

We have,

Total students in Orchestra= 75

Ratio of Girls to Boys = 3 :2

So, Number of Girls in Orchestra

= 3/5 x 75

= 3 x 15

= 45

and, Number of Boys in Orchestra

= 2/5 x 75

= 2 x 15

= 30

Thus, 30 Boys were in Orchestra.

Answer:  0.0386

Step-by-step explanation:

Given: The population of 400 tall women has a mean height[tex](\mu)[/tex] of 179.832 cm and a standard deviation[tex](\sigma)[/tex] of 12.192 cm.

Let X be a random variable that represents the height of woman.

Sample size : n= 50

The probability that the mean for this sample group is above 182.88 will be :

[tex]P(\overline{X}>182.88)\\\\=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{182.88-179.832}{\dfrac{12.192}{\sqrt{50}}})\\\\ =P(Z>1.7678)\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=1-P(Z<1.7678)\\\\=1-0.9614\ \ \ [\text{By p-value table}]\\\\= 0.0386[/tex]

Answer:

Wouldn't it be just 2 since it's already solved

Step-by-step explanation:

It is given that,

Distance, d = 15 m

Speed of Kim,v = 1.5 m/s

We need to find the equation that gives the relationship between Kim's distance from the starting line d and the time t. Speed of an object is given by :

speed = distance/time

⇒ [tex]t=\dfrac{d}{v}[/tex]

Putting all the values,

[tex]t=\dfrac{15\ m}{1.5\ m/s}\\\\t=10\ s[/tex]

Hence, this is the required solution.

Answer: 6

Step-by-step explanation: The y-intercept is 6 and the slope is -2.

First, we subtract 10x.

5y = -10x+30

Then we divide by 5.

y = -2x + 6

Now we have everything we need!

So the y-intercept is 6.

Hope this helps! :)

The y-intercept is "6".

Given:

[tex]10x+5y=30[/tex]

y-intercept

[tex]10x+5y=30[/tex] y-intercepts

When y-intercepts the value it indicates that x=0 then

[tex]\to 10x+5y=30\\\\\to 10(0)+5y=30\\\\\to 5y=30\\\\\to y=\frac{30}{5}\\\\\to y=6[/tex]

When the y-intercept is value will be "6".

Answer:

y = x + 4

Step-by-step explanation:

For a line to be Parallel it has to have the same slope but different y intercept

Answer:

1

Step-by-step explanation:

This equation is written in the

y = mx + b,

where "m" is the slope, and "b" is the y-intercept.

In this case, m=1, hence the "x" has no coefficient; therefore, the slope of the given line is 1.

When 2 lines are parallel, they run next to each other, for infinitely long, yet they never touch. This means that 2 parallel lines have the same slope. Hence a line running parallel to the given one will also have a slope of 1.

Answer:

No, he won't

Step-by-step explanation:

Given

Target = 480 pages in 28 days

Rate = 60 pages in 4 days

Required:

Determine if he'll reach his target

The rate can be expressed using:

[tex]Rate = \frac{Pages}{Days}[/tex]

So, we have:

[tex]Rate = \frac{60\ pages}{4\ days}[/tex]

Multiply the fraction by [tex]\frac{7}{7}[/tex]

[tex]Rate = \frac{60\ pages}{4\ days} * \frac{7}{7}[/tex]

[tex]Rate = \frac{60\ pages * 7}{4\ days * 7}[/tex]

[tex]Rate = \frac{420\ pages}{28\ days}[/tex]

This can be interpreted as: 420 pages in 28 days

And his target is 480 pages in 28 days

Hence, he wont finish the book at that rate

[tex]\displaystyle \frac{x^2+3x+2}{1-x}<0[/tex]

Step-by-step explanation:

Rational Inequality

We are given the solution of rational inequality:

(-2,-1) U (1,∞)

The first set suggests a limited zone than can be obtained by a quadratic equation of the form:

[tex](x-a)(x-b)<0[/tex]

Where a and b are the roots of the equation, which coincide with the endpoints of the interval. Thus, to get the interval, we can use:

[tex](x+2)(x+1)<0[/tex]

Operating:

[tex]x^2+3x+2<0[/tex]

The second set is an open infinite interval, that can be modeled as a third binomial that changes signs in x=1 and is in the denominator, so x=1 is not included.

Thus, one possible inequality is:

[tex]\mathbf{\displaystyle \frac{x^2+3x+2}{1-x}<0}[/tex]

The solution to the inequality (-2,-1)U(1, ∞) is (-2, ∞)

An inequality is an expression used to show the relationship between two or more numbers and variables.

A rational inequality is an inequality that contains a rational expression.

Given the inequality (-2,-1)U(1, ∞).

The solution to the inequality is (-2, ∞)
