plsss beggg i need this right now. deadline now at 6:00 pm and it's 5:03 here so please answer this :(​

Answer:

Step-by-step explanation:

Expression evaluated by the student is,

(-4 + x)

For x = [tex]-9\frac{1}{2}[/tex]

Value of the expression will be,

(-4 + x) = [tex]-4+(-9\frac{1}{2})[/tex]

           = [tex]-4-9-\frac{1}{2}[/tex]

           = [tex]-13-\frac{1}{2}[/tex]

           = [tex]-13\frac{1}{2}[/tex]

While student evaluated the value of the expression as [tex]-5\frac{1}{2}[/tex].

Mistake done by the student may be in the first step [tex][-4+(-9\frac{1}{2})][/tex].

He might have subtracted [tex](-9\frac{1}{2})[/tex] from (-4).

Answer:

12:45 pm

Step-by-step explanation:

First we find out the amount of time it takes to drive 90 miles at 60 mph.

speed = distance/time

time * speed = distance

time = distance/speed

time = 90 miles / 60 mph

time = 1.5 hour = 90 minutes

It takes 1.5 hour, or 90 minutes, to drive 90 miles at a speed of 60 mph.

To get there at 2:00 pm, he should have left at 12:30 pm.

He got there 15 minutes late, so he must have left 15 minutes late.

He left at 12:45 pm.

Answer: 12:45 pm

Answer:

Step-by-step explanation:

Median - The middle number in a list of numbers starting from least to greatest.

Knowing this, we can start.

The first step is to rewrite all the numbers from least to greatest

15, 19, 28, 32, 43, 52, 66, 72, 72, 81

Now cross off a number from the least and greatest until there is 1 or 2 numbers left

19, 28, 32, 43, 52, 66, 72, 72

28, 32, 43, 52, 66, 72

32, 43, 52, 66

43, 52

If you are left we 1 number, that is your answer. If you are left with 2 numbers, there is an extra step

In the case that you have 2 numbers, you need to add them together, and divide by 2

43 + 52 = 95

95 ÷ 2 = 47.5

Thus 47.5 is our answer

Answer:

median is 55

Answer:

15!

Step-by-step explanation:

so 40 people volentered to bring cakes, but 10 brought 2. So (30*1)+(10*2)=50 cakes. So, 30 percent of 50 cakes would be 15. To double check, times 50 by 100 and then 30 percent would become 30 (making super sure the actual answer is 15)

All angles make up 540°.

Use an algebra expression to clarify this.

9x+7x+15+5x-25+6x+25+6x-3=540

Add like terms.

33x+12=540

33x=528

x=16

The quotient and remainder of the polynomial after division are u²+5u-2 and 0 respectively.

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables.

Given is a polynomial p(u) =u³+3u²-12u+4  which is to be divided by g(u)=u-2

When we divide the polynomial, we get,

Quotient = u²+5u-2

And for this remainder will be zero

Hence, the quotient and remainder of the polynomial after division are u²+5u-2 and 0 respectively.

Answer:

x= 154°

I hope it's helps you

Answer:

x=154

Step-by-step explanation:

The figures provides us with a variable and the number 154.

In this situation, the value of x and the given angle are  corresponding angles.

The theorem of corresponding angles states that if a transversal is cut by two parallel lines the corresponding angles are CONGRUENT.

When an angle is congruent, they are equal to each other.

So in this case, x=154, x≅154.

Since the quadrilateral is inscribed into circle, its opposite angles are supplementary:

Substitute the values and solve for x:

Answer:

According to the property of Cyclic Quadrilateral

5x - 22 + 8x + 7 = 180

(5x + 8x) - (22 - 7) = 180

13x - 15 = 180

13x = 180 + 15

13x = 195

x = 195/13

x = 15

Answer:

She has to make 25 consecutive free throws

Step-by-step explanation:

Let the number of consecutive throws be x

So, that would mean the number of free throws would total 25 + x

while the number of free throws made would be 15 + x

So for us to have an 80% raise ;

That would mean;

(15 + x)/(25 + x) * 100 = 80

100(15 + x) = 80(25 + x)

1500 + 100x = 2000 + 80x

2000-1500 = 100x-80x

20x = 500

x = 500/20

x = 25

Answer:

2.2

Step-by-step explanation:

if force equals mass times acceleration then you divide 7.92(the force) by 3.6(the mass) to find out what would be multiplied by 3.6 to get 7.92.

Sorry if I'm wrong.

The acceleration of an object with F=7.92 newtons and m=3.6 kilograms is 2.2 m / s²

Force is a pull or push upon an object that causes motion .

Mathematically, force is express as follows:

F = ma

where

m = mass

a = acceleration

Force is measured in Newton.

Let's find the acceleration of an object with F =7.92 newtons and m = 3.6 kilograms.

7.92 = 3.6a

divide both sides by 3.6

a = 7.92 / 3.6

a = 2.2 m / s²
