Raul can spend not more than $ 38.22 on the pair of jeans

<em><u>Solution:</u></em>

Raul plans to spend no more than $78.00 on two shirts and a pair of jeans

He bought the two shirts for $19.89 each

Therefore,

cost of 2 shirts = 19.89 x 2 = $ 39.78

Let "x" be the cost of pair of jeans

Then we frame a inequality as:

cost of 2 shirts + cost of pair of jeans \leq 78

39.78 + x\leq 78

Here we have used "less than or equal to" symbol, because he spend no more than $ 78

Solve the inequality for "x"

39.78 + x\leq 78\\\\Subtract\ 39.78\ from\ both\ sides\\\\x\leq 78-39.78\\\\x\leq 38.22

Thus, he can spend not more than $ 38.22 on the pair of jeans

A drink is made by mixing 650 ml of water with 150 ml of fruit juice.
Luda [366]
<h2>○=> <u>Correct answer</u> :</h2>

\boxed{\color{hotpink}\tt18.75\%} of the drink is fruit juice

<h3>○=> <u>Steps to derive correct answer</u> :</h3>

Quantity of water in a drink = 650 ml

Quantity of fruit juice in a drink = 150 ml

Total quantity of both items in the drink :

=\tt 650 + 150

\color{plum}=\tt 800 \: ml

Thus, the total quantity of both items in the drink = 800 ml

Let the percentage of of fruit juice in the drink be x%.

Which means :

=  \tt\frac{x}{100}  \times 800 = 150

= \tt \frac{x \times 800}{100}  = 150

=\tt  \frac{800x}{100}  = 150

=\tt 8x = 150

=\tt x =  \frac{150}{8}

\hookrightarrow\color{plum} \bold{x = 18.75\%}

Then, the percentage of water in the drink :

= \tt100 - 18.75

\color{plum}= \tt81.25\%

Thus, the percentage of water in the drink = 81.25%

<h3>○=> <u>Therefore</u> :</h3>

▪︎Percentage of fruit juice in the drink = 18.75%

▪︎Percentage of water in the drink = 81.75%

Find 2004-04-02-04-00_files/i0340000.jpg. Round the answer to the nearest tenth.
lesya692 [45]

<span>The problem is to calculate the angles of the triangle. However, it is not clear which angle you have to calculate, so we are going to calculate all of them
</span>
we know that
Applying the law of cosines
c²=a²+b²-2*a*b*cos C------> cos C=[a²+b²-c²]/[2*a*b]
a=12.5
b=15
c=11
so
 cos C=[a²+b²-c²]/[2*a*b]--->  cos C=[12.5²+15²-11²]/[2*12.5*15]
cos C=0.694------------> C=arc cos (0.694)-----> C=46.05°-----> C=46.1°

applying the law of sines calculate angle B
15 sin B=11/sin 46.1-----> 15*sin 46.1=11*sin B----> sin B=15*sin 46.1/11
 sin B=15*sin 46.1/11-----> sin B=0.9826----> B=arc sin (0.9826)
B=79.3°

calculate angle A
A+B+C=180------> A=180-B-C-----> A=180-79.3-46.1----> A=54.6°

the angles of the triangle are
A=54.6°
B=79.3°
C=46.1°

Q(x)=4x2-3x3+8x is it a cubic trinomial​
Norma-Jean [14]

Answer:

Yes

Answer:    x = 0

Step-by-step explanation:

Yes it is.

Down is the answer how to solve this equation and the steps.

Step  1  :

Equation at the end of step  1  :

 qx -  (((4 • (x2)) -  3x3) +  8x)  = 0  

Step  2  :

Equation at the end of step  2  :

 qx -  ((22x2 -  3x3) +  8x)  = 0  

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  qx + 3x3 - 4x2 - 8x  =  

 x • (q + 3x2 - 4x - 8)  

Equation at the end of step  4  :

 x • (q + 3x2 - 4x - 8)  = 0  

Step  5  :

Theory - Roots of a product :

5.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

5.2      Solve  :    x = 0  

 Solution is  x = 0

Solving a Single Variable Equation :

5.3     Solve   q+3x2-4x-8  = 0

In this type of equations, having more than one variable (unknown), you have to specify for which variable you want the equation solved.

Answer:  x = 0

Hope this helps.
