Answer 1

Answer:

x=3

Step-by-step explanation:

so in order to solve this question we are going to plug in u for 2^x

3((2^x)/2)=2^x+4

3u/2=u+4

3u=2u+8

u=8

we can put 2^x back into the equation in order to find x

2^x=8

2^x=2^3

x=3

The length of a rectangle is 3 m less than double the width, and the area of the rectangle is 44 m. Find the dimensions of the rectangle

Answers

Answer:

Length of Rectangle is 3 cm less than twice the width

Area is 44 m2 ; let W = width;  2W - 3 = Length

Arect = L times W

44 = W ( 2W - 3 )

44 = 2W2 - 3W

0 = 2W2 - 3W - 44

Factoring

0 = ( 2W - 11 )( W +4)

2W - 11 =0   ;            W + 4 = 0

       W = 11/2                 W = -4  (width can not be a negative number)

Therefor: width is 11/2  and length is 8

What is the value of x? *
31°
53°

Answers

Answer:

X = 96

Step-by-step explanation:

This one is pretty simple

So we're dealing with angles here.

So what we want to do is add the two angles and it =180

Here's the equation so it makes more sense:

[tex]A+B=180[/tex]

so we'd place in those numbers

[tex]53+31=180[/tex]

add the two angles together

[tex]53+31=84[/tex]

than we'd subtract from 180 getting the value of X

[tex]180-84=96[/tex]

[tex]x=96[/tex]

X= 96

I am doing angel right now and I’ve don’t that one before it isn’t that hard.

(y+7) what does that equal

Answers

You don’t know because y isn’t an actually number unless you know what it’s supposed to equal. For example, if y=18, y+7 would be 25 but since you don’t know what y is, it’s undefined.
(y+7) is undefined and cannot rlly be added together since y isn’t really a number. Remove the parenthesis and ur answer is simply : y+7

Answer: The value of x is 6.

Step-by-step explanation:

In the figure we have two secants.

A secant is a line that intersects a circle in exactly two points.

For the figure attached below:

[tex]a\times b=c\times d[/tex]

So for the given figure,

[tex]x\times 8=4\times (4+8)\\\\\Rightarrow\ x=\dfrac{4\times12}{8}\\\\\Rightarrow\ x=6[/tex]

Hence, The value of x is 6.

Hello again, hehelol12.

PQ is equal to CB. So the length of PQ must be 9.

Angle PQR is equal to CBA. Therefore the measure of angle PQR is 46.

I hope this helps!

Step-by-step explanation:

since they are congruent triangles, all your have to done is the compare the longest side of the first triangle is equal to that of the other; the smallest side of the first triangle is equal to that of the second, and so for the corresponding angles

using the above method,

Answer:

a) from mere observation line PQ is the longest therefore it is equal to the length of the longest side of the other triangle. so line PQ = 9

b) again, ang PQ is the smallest, using the method, ang PQ = 46 degrees

but mind you, you could use a ruler to measure the length to find the longest more accurately.

A carpenter lays 18 square feet of tile in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?

Answers

Answer:

x=24

Step-by-step explanation:

there are different ways to solve the problem

set up a proportion:

16/(2/3)=x/1

cross multiply

(2/3)x=16

(3/2)(2/3)x=(3/2)(16)

x=24 square feet per hour

a carpenter lays 16 square feet in 40 minutes (2/3 of an hour)

this means he lays 4 square feet every 10 minutes

8 square feet in 20 minutes

12 square feet in 30 minutes

24 square feet in 60 minutes

Explain why dividing each side of \small 3x^2=6x by \small 3x is not a reliable way to solve the equation.

Answers

Answer:

See Explanation

Step-by-step explanation:

Given

[tex]3x^2 = 6x[/tex]

Required

Why dividing by [tex]3x[/tex] is not reliable

The reason is that, the given expression is a quadratic equation and as such, it will most likely have two solutions.

So, when the expression is divided by [tex]3x[/tex], the solution will be [tex]x = 2[/tex], leaving out the other possible solution.

The right way is:

[tex]3x^2 = 6x[/tex]

Subtract 6x from both sides

[tex]3x^2 - 6x = 6x - 6x[/tex]

[tex]3x^2 - 6x = 0[/tex]

Factorize

[tex]3x(x - 2) = 0[/tex]

Split

[tex]3x = 0\ or\ x - 2 = 0[/tex]

Solve for x in both cases:

[tex]x = 0\ or\ x = 2[/tex]

Answers

Answer:

Red

Step-by-step explanation:

Let x = number of laps and Let y = time taken to complete laps

She is able to run one lap in 7 minutes

Given this information we want to create an equation

the equation would be

7x = y

Now that we have created an equation we want to find how many laps she can run in 56 minutes.

The time is represented by 7 so we plug in 56 into y

so now we have

7x = 56

Finally we solve for x

*divide each side by 7*

56/7 = 8

7x / 7 = x

we're left with x = 8 meaning that she can run 8 laps in 56 minutes

In conclusion the answer is the Red one

The amount after 3 years at 5.5% is therefore:
