Evaluate the expression. 7 x (33 - 18) need a anwser fast

Answer:

12 pieces

Step-by-step explanation:

75 divided by 6 1/4= 12 pieces

To find the x-intercept of the linear equation y = 1/4x + 5/4, substitute y = 0 into the equation and solve for x. The x-intercept is -5.

To find the x-intercept of the graph of the equation y = 1/4x + 5/4, we need to set the y-value to 0 and solve for x.

So, by substituting y = 0 into the equation, we get 0 = 1/4x + 5/4.  

Now, we can solve for x by isolating x on one side of the equation. Subtracting 5/4 from both sides gives us -5/4 = 1/4x. Multiplying both sides by 4 gives us -5 = x, or x = -5.

Therefore, the x-intercept of the graph is -5.

The original selling price of the ski set is $585.71.

Step 1: Determine the final sale price after the first markdown

The one-day sale price of the ski set is $328, and the first markdown is 20%. To find the final sale price after the first markdown, we can set up the equation:

0.80 × Original Price = $328

Solving for the original price, we get:

Original Price = $328 / 0.80 = $410

Therefore, the final sale price after the first markdown is $410.

Step 2: Determine the original selling price

The final sale price after the first markdown is $410, and the second markdown is 30%. To find the original selling price, we can set up the equation:

0.70 × Original Price = $410

Solving for the original price, we get:

Original Price = $410 / 0.70 = $585.71

Therefore, the original selling price of the ski set is $585.71.

The speed at which the satellite travel is 6.80 miles per second

Step-by-step explanation:

Given as :

The distance cover by satellites = 29 [tex]\frac{1}{2}[/tex]  miles

Or, The distance cover by satellites  = [tex]\frac{59}{2}[/tex] miles

The Time taken by satellite to travel with this speed = 4[tex]\frac{1}{3}[/tex] sec

Or, The Time taken by satellite to travel with this speed = [tex]\frac{13}{3}[/tex] seconds

Let the Speed with which the satellite travel = s miles per second

Now, As we know

Speed = [tex]\dfrac{\textrm Distance}{\textrm Time}[/tex]

Or, s = [tex]\frac{\frac{52}{2}}{\frac{13}{3}}[/tex]

or, s = [tex]\frac{59\times 3}{2\times 13}[/tex]

∴ s = 6.80 mps

So, speed = s = 6.80 miles per second

Hence The speed at which the satellite travel is 6.80 miles per second Anwser

Problem 1

A = 5! = 5*4*3*2*1 = 120 ways to arrange the math books

B = 4! = 4*3*2*1 = 24 ways to arrange the French books

C = 2! = 2*1 = 2 ways to arrange the biology books

D = 3! = 3*2*1 = 6 ways to arrange the three blocks of books, each block a different subject

E = A*B*C*D = 120*24*2*6 = 34560 different ways to arrange the books such that the subjects stick together

-------------

========================================

Problem 2

Group all the math books to form one "book". This is the same as taking out the 5 math books and replacing it with one single math book. This single math book acts as a placeholder for all of the five books together as one block.

We have

1 math "book"

4 French books

2 biology books

So there are 1+4+2 = 7 "books" total and

7! = 7*6*5*4*3*2*1 = 5040 different ways to arrange those "books"

Within the math block of books, there are 5! = 120 ways to arrange things.

So overall we have 120*5040 = 604800

Answer:

The set of integer between 4 and 8 = { 5, 6, 7 }.

Step-by-step explanation:

Set:

A set is a well-defined  collection of distinct objects, elements encloses in curly bracket.  

For example.

set of vowels = { a, e, i, o, u }

set of any three Capital alphabets = { A, B ,Z }

set of cars = { Ferrari, Volvo, Mercedes, Audi }

Now we want set of integer between 4 and 8

Integer: All the positive and negative natural numbers are called integers.

-1, -2, -3, 1, 2, 3, 4, 5, 6 ,7 , 8 ..

The set of integer between 4 and 8 = { 5, 6, 7 }.

Answer:

Step-by-step explanation:

if I understand correctly the problem is

(2*X)-(3/4)=1/2

to solve for x we need to isolate it, the first step in doing so is getting rid of the 3/4

2*X-3/4+3/4=1/2+3/4

simplify

2*X=1 1/4

the next step is getting rid of the 2

(2*X)/2=(1 1/4)/2

simplify

Answer:

The amount charged is proportional to the ears of corn

Step-by-step explanation:

Now I'm going to explain, but write it in your own words. It's proportional because the amount charged is completely reliant on how many ears of corn you are buying.

So for every 1 ear of corn, you pay about 33 cents

or

For every 2 ears of corn, you pay about 67 cents

After 5.11 years, amount due reach $65,000 or more

Solution:

Given that a loan of $46,000 is made.

Rate of interest charged is 7% compounded annually

Need to determine number of years in which the amount due reach $65,000 or more.

In our case

Amount due A = $65000

Loan Amount that is principal P = $46000

Rate of interest r = 7%

Formula for Amount compounded anually is as follows:

[tex]\mathrm{A}=P\left(1+\frac{r}{100}\right)^{n}[/tex]

Substituting the values in above formula we get

[tex]\begin{array}{l}{65000=46000\left(1+\frac{7}{100}\right)^{n}} \\\\ {\frac{65000}{46000}=\left(\frac{107}{100}\right)^{n}} \\\\ {\Rightarrow 1.4130=(1.07)^{n}}\end{array}[/tex]

Applying log on both sides, we

[tex]\begin{array}{l}{\ln 1.4130=n \ln 1.07} \\\\ {=>\frac{\ln 1.4130}{\ln 1.07}=\mathrm{n}} \\\\ {=>\mathrm{n}=\frac{0.34571}{0.067658}=5.1096=5.11}\end{array}[/tex]

Hence after 5.11 years , amount due reach $65,000 or more

Answer:

The amount invested in the mutual fund that earned 5% was $1,000

The amount invested in the mutual fund that earned 3% was $1,800

Step-by-step explanation:

Let

x ----> the amount invested in the mutual fund that earned 5%

y ----> the amount invested in the mutual fund that earned 3%

we know that

[tex]x+y=2,800[/tex] ----> [tex]y=2,800-x[/tex] ----> equation A

[tex]5\%=5/100=0.05[/tex]

[tex]3\%=3/100=0.03[/tex]

[tex]0.05x+0.03y=104[/tex] ----> equation B

Solve the system by substitution

substitute equation A in equation B

[tex]0.05x+0.03(2,800-x)=104[/tex]

Solve for x

[tex]0.05x+84-0.03x=104[/tex]

[tex]0.05x-0.03x=104-84[/tex]

[tex]0.02x=20[/tex]

[tex]x=\$1,000[/tex]

Find the value of y

[tex]y=2,800-x[/tex]

[tex]y=2,800-1,000=\$1,800[/tex]

therefore

The amount invested in the mutual fund that earned 5% was $1,000 and the amount invested in the mutual fund that earned 3% was $1,800

Answer:

C. y +3 = x +3

Step-by-step explanation:

We need to find in below option x has direct variation with y.

We solve for each;

A. [tex]2y = 3x-7[/tex]

From above equation we can state that 2 times y is equal to 7 less than 3 times of x.

Hence it doesn't represent direct variation.  

B. [tex]y-4 = x+6[/tex]

Solving above expression we get;

[tex]y-4 = x+6\\y = x+6+4\\y=x+10[/tex]

From above equation we can state that y is equal to 10 more than x.

Hence it doesn't represent direct variation.

C. [tex]y+3 = x+3[/tex]

Solving above expression we get;

[tex]y+3 = x+3\\y = x+3-3\\y=x[/tex]

From above equation we can state that y is equal to x.

Hence it represent direct variation.

D. [tex]4y+1 = 4x-1[/tex]

Solving above expression we get;

[tex]4y+1 = 4x-1\\4y = 4x-1-1\\4y=4x-2[/tex]

From above equation we can state that 4 times y is equal to 2 less than 4 times of x.

Hence it doesn't represent direct variation.

Hence the Answer which represent direct variation of x and y is,

C. [tex]y+3 = x+3[/tex]

Answer:

The value of sin t is [tex]\frac{7}{25}[/tex]

Step-by-step explanation:

Given as :

cos (t) = [tex]\frac{24}{25}[/tex]

Since sin² t + cos² t = 1

So, sin² t = 1 - cos² t

or,  sin² t = 1 - ([tex]\frac{24}{25}[/tex])²

or,  sin² t = [tex]\frac{25^{2} - 24^{2} }{25^{2} }[/tex]

Or,  sin² t = [tex]\frac{625 - 576}{625}[/tex]

Or ,   sin² t = [tex]\frac{49}{625}[/tex]

Or, sin t = [tex]\sqrt{\frac{49}{625} }[/tex]

So, sin t = [tex]\frac{7}{25}[/tex]

Hence The value of sin t is [tex]\frac{7}{25}[/tex]   Answer

Answer:

Monthly Salary = $2,600

Step-by-step explanation:

Monthly rent on monthly salary = 25%

Monthly rent = $650.

To determine the monthly sale, we have to use the unitary method.

25% monthly rent on monthly salary means out of $100, Deja spends $25 on her rent.

Therefore,

Deja spends $25 on her rent, when the monthly salary   = $100

Deja spends $1 on her rent, when the monthly salary      = [tex]\frac{100}{25}[/tex]

Deja spends $650 on her rent, when the monthly salary = [tex]\frac{100*650}{25}[/tex]

= [tex]\frac{65000}{25}[/tex]

= $2,600

Her monthly salary is $2,600.

Answer:

∠A=67°

∠B=70°

Step-by-step explanation:

The correct question in English is

Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.

we know that

The measure of the interior angles in a triangle must be equal to 180 degrees

so

∠A+∠B+∠C=180°

substitute the given values

[tex](3x+1)\°+(3x+4)\°+(2x-1)\°=180\°[/tex]

solve for x

[tex](8x+4)\°=180\°[/tex]

[tex]8x=180-4[/tex]

[tex]x=22[/tex]

Find the measure of each angle

∠A=(3(22)+1)=67°

∠B=(3(22)+4)=70°

∠C=(2(22)-1)=43°

Answer:

$25.30

Step-by-step explanation:

The final bill was $25.30 if you get a haircut that cost $23.if you tip the barber 10% of the total haircut cost.

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

It is given that:

You get a haircut that cost $23.if you tip the barber 10% of the total hair cut cost.

Let x be the final bill amount.

The value of x can be found as follows:

x = $23 + 10% of $23

x = 23 + (10/100)23

x = 23 + 0.1(23)

x = 23 + 2.30

x = $25.30

Thus, the final bill was $25.30 if you get a haircut that cost $23.if you tip the barber 10% of the total haircut cost.
