$768.54 (Approximate)

Step-by-step explanation:

Trey is taking out a loan for $85000. It is a 20-year loan with an APR of 5.85%.

Therefore, if we consider the interest rate is simple interest, then using the simple interest formula, the sum will become after 20 years

[tex]85000(1 + \frac{5.85 \times 20}{100}) = 184450[/tex] dollars.

To evaluate the expression 4c - x with c=5 and x=-4, substitute the values to get 4*5 - (-4), which simplifies to 20 + 4, resulting in a value of 24.

To evaluate the expression 4c-x when c=5 and x=-4, substitute the given values for the variables c and x into the expression.

Step 1: Substitute c = 5 into the expression.

4 × 5 - x

Step 2: Substitute x = -4 into the expression.

4 × 5 - (-4)

Step 3: Carry out the multiplications and additions.

20 - (-4) = 20 + 4

Step 4: Add the numbers.

20 + 4 = 24

Therefore, when c = 5 and x = -4, the value of the expression 4c - x is 24.

The value of the expression 4c-x when c=5 and x=-4 is 24.

To evaluate the expression (4c - x) when (c = 5) and (x = -4), follow these steps:

1. Substitute (c = 5) into the expression: [tex]\(4 \times 5 - x\)[/tex]

2. Substitute (x = -4) into the expression: [tex]\(4 \times 5 - (-4)\)[/tex]

3. Simplify the multiplication: (20 - (-4))

4. Simplify further by changing the double negative to addition: (20 + 4).

5. Add the numbers: (20 + 4 = 24).

Therefore, when (c = 5) and (x = -4), the value of the expression (4c - x) is (24). The process involves substituting values, simplifying, and performing addition to obtain the final result.

900 × 2 ?

Step-by-step explanation:

900 × 2 ? i dont know but i hope its correct?

The solution is [tex](-1,5)[/tex] and [tex](7,-3)[/tex]

Step-by-step explanation:

The expression is [tex]x^{2} +y^{2} -x+3y-42=0[/tex] and [tex]x+y=4[/tex]

Using substitution method we can solve the expression.

Let us substitute [tex]x=4-y[/tex] in [tex]x^{2} +y^{2} -x+3y-42=0[/tex]

[tex](4-y)^{2} +y^{2} -(4-y)+3y-42=0[/tex]

Expanding and simplifying the expression, we get,

[tex]\begin{array}{r}{16-8 y+y^{2}+y^{2}-4+y+3 y-42=0} \\{2 y^{2}-4 y-30=0}\end{array}[/tex]

Let us use the quadratic equation formula to solve this equation,

[tex]\begin{aligned}y &=\frac{4 \pm \sqrt{16-4(2)(-30)}}{2(2)} \\&=\frac{4 \pm \sqrt{16+240}}{4} \\&=\frac{4 \pm 16}{4} \\y &=1 \pm 4\end{aligned}[/tex]

Thus, [tex]y=5[/tex] and [tex]y=-3[/tex]

Substituting y-values in the equation [tex]x+y=4[/tex], we get the value of x.

For [tex]y=5[/tex] ⇒ [tex]x=4-5=-1[/tex]

For [tex]y=-3[/tex] ⇒ [tex]x=4+3=7[/tex]

Brad spends about the same amount of time doing homework as he does watching videos. The other statements are not true.

The circle graph shows how Brad spends his time outside of school. To determine which statements are true, we need to compare the different activities.

A. To compare working and homework, we can see that Brad spends about ⅔ of his time working and ⅓ of his time on homework. So, A is not true since Brad spends more time on homework than working.

B. To compare watching videos and reading with playing the piano and soccer, we can see that Brad spends about 1/6 of his time on watching videos and reading, and about 3/6 of his time on playing the piano and soccer. So, B is not true since Brad spends more time playing the piano and soccer than watching videos and reading combined.

C. To compare doing homework and watching videos, we can see that Brad spends about ⅓ of his time on both activities. So, C is true since Brad spends about the same amount of time doing homework as he does watching videos.

D. To compare playing piano with playing football and soccer combined, we can see that Brad spends about 1/6 of his time on playing piano, and about 4/6 of his time on playing football and soccer combined.

Answer:

The slope of given relationship is 7 and it is not - 3  

Step-by-step explanation:

Given as :

The distance cover while walking = d = 21 miles

The speed rate of walking = s = 3 miles per hour

Let The time taken to cover 21 miles = t hours

Now, According to question

∵ Distance = Speed × Time

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

Or, t = [tex]\dfrac{d}{s}[/tex]

Or, t = [tex]\dfrac{\textrm 21 miles}{\textrm 3 miles per hour}[/tex]

∴  t = 7 hours

So,  The time taken to cover 21 miles = t = 7 hours

Answer:

The answer that gives the best estimate is (1,1)

Step-by-step explanation:

i) As can be seen on of the lines intercepts the y axis at (0,-1). So the y

 intercept or [tex]c_{1}[/tex] = -1. Therefore the equation for this line can be written as

 y = [tex]m_{1}[/tex] x + [tex]c_{1}[/tex]    ⇒    y = [tex]m_{1}[/tex] x - 1 . It can also be seen from this graph that the

 line passes through the point (2 , 2). Substituting these values for x and y  

 respectively we get  2 = 2[tex]m_{1}[/tex] - 1    ∴ [tex]m_{1}[/tex] = [tex]\frac{3}{2}[/tex].  The equation of the first line

 can be written as y = [tex]\frac{3}{2}[/tex] x - 1   ⇒ 2y - 3x = -2

ii) As can be seen on the other line the intercept on the y axis is at (0,2). So

  the y  intercept or [tex]c_{2}[/tex] = 2. Therefore the equation for this line can be  

  written  as  y = [tex]m_{2}[/tex]x + [tex]c_{2}[/tex]    ⇒    y = [tex]m_{2}[/tex] x + 2 . It can also be seen from this  

   graph that  the  line passes through the point (1 , -1). Substituting these

   values for x and  y   respectively we get  1 = 1[tex]m_{2}[/tex] + 2    ∴ [tex]m_{2}[/tex]  = -1 .  The

   equation of the second line  can be written as y = - x + 2   or x + y = 2

iii) Solving the two equations of the two lines respectively as found in i) and

  ii)  we get y = 0.8. We multiply equation in ii) by 3 to get 3x + 3y = 6 and  

  when we add this to equation in i) we get 5y = 4 which means that y = 0.8.

  If we substitute this value in ii) we get 0.8 + x = 2 , therefore x = 1.2.

iv) Therefore we get the solution of the two lines, which is the intersection

    of the two lines as (1.2, 0.8). So the answer that gives the best estimate

    is (1,1)

Answer:

mAngle2 = 50°

Step-by-step explanation:

A relative schematic has been attached bellow describing the problem.

In this case, we will be working with Supplementary angles. The latter denote angles which when summed together equal to 180°.

From the schematic we can identify the following Supplementary pairs as:

∠1 and ∠2

∠2 and ∠(18x+4)

∠(18x+4) and ∠(7x+1)

∠(7x+1) and ∠1

So lets start by finding the value of [tex]x[/tex] as follow. Since we know the supplementary pairs we have that

[tex](18x+4)+(7x+1)=180\\18x+7x+4+1=180\\25x+5=180\\25x=180-5\\25x=175\\x=\frac{175}{25} \\x=7[/tex]

Now we similarly know that ∠2 and ∠(18x+4) are supplementary. So lets replace the value of [tex]x[/tex] in ∠[tex]18x+4[/tex], we have

[tex]18(x=7)+4=126+4=130[/tex]

So finally we have

[tex]<2 + 130=180\\<2=180-130\\<2=50[/tex]

Thus we can say that ∠2 = 50° (which matches the second options from the available ones).

Answer:

12 bottles were sold in the second hour.

Step-by-step explanation:

This problem can be solved by implementing an equation in one variable.

The equation will utilize the given values including total bottles of juice, the amount of juice sold in the first hour and amount of juice remaining at the end.

The equation will also consist of the value to be found out, the amount of juice sold in the second hour.

The value to be found out is substituted by a variable.

The equation is then solved by transfer of values and/or variable on the opposite side of the equal sign.

When a value/ variable is transferred on the opposite side of the equal sign, the sign of the value/ variable becomes the opposite.

The negative sign becomes positive and multiplication becomes division, and vice-versa.

1. In the first hour, \frac{3}{15} of all the juice was sold.

\frac{3}{15} of 30 is calculated as

\frac{3}{15} x 30 = 6

6 bottles are sold in the first hour.

2. At the beginning of the second hour, the amount of juice remaining is assumed to be a.

3. As per the question, at the end of second hour, the remaining juice is \frac{6}{15}.

\frac{6}{15} of 30 is calculated as

\frac{6}{15} x 30 = 12

12 bottles are remaining at the end of the second hour.

4. Alternatively, at the end of second hour, 30 - 6 - a of the juice is remaining.

We get, 24 - a bottles are remaining at the end of the second hour.

We equate the above expression with 12, we get the following equation.

24 - a = 12

Next, we transfer a from left side to the right side of the equation.

24 = 12 + a

Next, we transfer 12 from right side to the left side of the equation.

24 - 12 = a

=> 12 = a

OR

a = 12

Hence, 12 bottles were sold in the second hour.

Mario sold 2/5 of his juice in the second hour after having sold 3/15 in the first hour and ending with 6/15 of the juice left.

Mario started with 30 bottles of juice and sold 3/15 of them in the first hour. To find out how many bottles that is, we multiply the total number of bottles by the fraction sold: 30 bottles x 3/15 = 6 bottles. After the first hour, Mario had 30 bottles - 6 bottles = 24 bottles left.

By the end of his shift, Mario had 6/15 of his original juice left. Again, we multiply the total number of bottles by the fraction left: 30 bottles x 6/15 = 12 bottles. So, at the end of his shift, Mario had 12 bottles unsold.

To find out how many bottles were sold in the second hour, we subtract the number left at the end from the number left after the first hour: 24 bottles - 12 bottles = 12 bottles sold in the second hour. To express this amount as a fraction of the original 30 bottles, we divide 12 by 30 to get 12/30, which simplifies to 2/5. Thus, Mario sold 2/5 of his juice in the second hour.

m∠A = 90°, m∠B = 60°, m∠C = 30°

Step-by-step explanation:

step 1

see the attached figure to better understand the problem

In this problem we have a right triangle, because the Pythagorean Theorem is satisfied

so

[tex]BC^2=AB^2+AC^2[/tex]

therefore

[tex]m\angle A=90^o[/tex]

step 2

Find the measure of angle B

we know that

In the right triangle ABC

[tex]cos(B)=\frac{AB}{BC}[/tex] ----> by CAH (adjacent side divided by the hypotenuse)

substitute the given values

[tex]cos(B)=\frac{12}{24}[/tex]

[tex]m\angle B=cos^{-1}(\frac{12}{24})=60^o[/tex]

step 3

Find the measure of angle C

we know that

[tex]m\angle B+m\angle C=90^o[/tex] ----> by complementary angles

we have

[tex]m\angle B=60^o[/tex]

substitute

[tex]60^o+m\angle C=90^o\\m\angle C=30^o[/tex]

Answer:

It is irrational

Step-by-step explanation:

if you combine a rational and irrational number it cannot be rational.

Adding a rational and an irrational number always results in an irrational number. The rational number doesn't affect the irrationality of the irrational number.

The result of adding a rational and an irrational number is always an irrational number. For example, if you add the rational number 2 (which can be expressed as a ratio of two integers) and the irrational number sqrt(2) (which cannot be expressed as a ratio of two integers).

The result is 2 + sqrt(2), which is an irrational number.

Because the rational number doesn't affect the irrationality of the irrational number, the sum remains irrational.
