w+2/3=2 5/6 what is w

Answer:

34

Step-by-step explanation:

We know the straight line is equal to 180°, and the three angles that make it are (x+12),100°, and x. We can use the equation 180=(x+12)+100+x to find x.

180=(x+12)+100+x

We can remove the parentheses and combine x plus x to 2x.

180=100+2x+12

100+12=112

so

180=112+2x

-112 -112

Answer:

1. 22 * 3 = t

2. 4 + 7 = f

Step-by-step explanation:

Addison brought 66 treats to school and Brady caught 11 fish last weekend.

To determine how many treats Addison brought to school, we can write the following equation: t/22 = 3, where t represents the number of treats. To solve for t, we can multiply both sides of the equation by 22 to get t = 3 * 22 = 66. Therefore, Addison brought 66 treats to school.

To determine how many fish Brady caught last weekend, we can write the equation: f - 4 = 7, where f represents the number of fish. To solve for f, we can add 4 to both sides of the equation to get f = 7 + 4 = 11. Therefore, Brady caught 11 fish last weekend.

Answer:

18.18 miles.

Step-by-step explanation:

A truck uses 1 tablespoon of gasoline to drive 125 yards.

Now, 1 gallon of gasoline contains 256 tablespoons of gasoline.

So, the truck uses 1 gallon i.e. 256 tablespoons of gasoline to drive (256 × 125) = 32000 yards.

Now, 1-mile distance contains 1760 yards.

Therefore, the truck uses 1 gallon of gasoline to drive [tex]\frac{32000}{1760} = 18.18[/tex] miles. (Answer)  

The lengths of the three sides of the triangle are 7m, 7m, and 12m.

Let the length of the two equal sides be 'x'.

The third side measures 2m less than twice the common length, so it is (2x - 2)m in length.

Given that the perimeter of the triangle is 26m, we can set up the equation:

x + x + (2x - 2) = 26

Simplifying the equation:

4x - 2 = 26

4x = 28

x = 7

So, the lengths of the three sides are 7m, 7m, and (2x - 2)m = (2 * 7 - 2)m = 12m.

#SPJ11

Final answer:

The triangle with two sides of equal length and a perimeter of 26 m has sides measuring 7 m, 7 m, and 12 m.

Explanation:

To solve for the lengths of the sides of the triangle described in the question, we can set up an equation based on the information given. Since two sides of the triangle have the same length, we can call that common length 'x'. The third side is described as being '2 m less than twice the common length', which can be written as '2x - 2'. The perimeter of the triangle, which is the sum of the lengths of all sides, is given as 26 m.

Therefore, the perimeter equation would be:

x + x + (2x - 2) = 26

This simplifies to:

4x - 2 = 26

Adding 2 to both sides, we get:

4x = 28

Dividing both sides by 4, we find x:

x = 7

Now we know that the two sides of equal length are both 7 m, and the third side is:

2x - 2 = 2(7) - 2 = 12

So the lengths of the three sides of the triangle are 7 m, 7 m, and 12 m.

Answer:

51.06

Step-by-step explanation:

So

P=$925

R=2.3%

T=2.4

So to get the answer we would need to multiply all of these together so first we would do 925 times 2.3% which would be 21.275. Then we would do 21.275 times 2.4 then we would get the answer of 51.06.

Joyce: y = 2x + 7

Haley: y = 3x

From looking at these two equations, we can assume that Haley will eventually catch up and pass Joyce because she sells items for $3 whereas Joyce had a head start of $7, but only sells items for $2.

Using substitution, we plug in y = 3x into y in the first equation: 3x = 2x + 7

This leaves us at x = 7.

y = 3(7) or 21.

The point at which Haley's and Joyce's money will be exactly the same is (7, 21). After this point, Haley will have more money.

Answer:

57

Step-by-step explanation:

The midsegment is one half the length of the third side of the triangle, that is

6x + 3 = [tex]\frac{1}{2}[/tex](3x + 87)

Multiply both sides by 2 to clear the fraction

12x + 6 = 3x + 87 ( subtract 3x from both sides )

9x + 6 = 87 ( subtract 6 from both sides )

9x = 81 ( divide both sides by 9 )

x = 9

Thus

midsegment = 6x + 3 = 6(9) + 3 = 54 + 3 = 57

Jason needs to ride 0.75 miles more to reach the end of the path

Solution:

Given that Jason begins at the start of a path and rides his bike [tex]11\frac{1}{2}[/tex] miles on the path

From given information,

[tex]\text{Total length of path } = 12\frac{1}{4} \text{ miles } = \frac{4 \times 12 + 1}{4} = \frac{49}{4} \text{ miles }[/tex]

[tex]\text{Distance covered already } = 11\frac{1}{2} \text{ miles } = \frac{11 \times 2 +1}{2} = \frac{23}{2} \text{ miles }[/tex]

To find: Distance in miles Jason must ride to reach the end of the path

Thus subtracting distance already covered from total distance, we get the distance Jason must ride to reach the end of the path

[tex]\text{Distance needed } = \text{Total length of path } - \text{Distance already covered }\\\\\text{Distance needed } = \frac{49}{4} - \frac{23}{2}\\\\\text{Distance needed } =\frac{49}{4} - \frac{23 \times 2}{2 \times 2}\\\\\text{Distance needed } =\frac{49}{4} - \frac{46}{4} = \frac{49-46}{4} = \frac{3}{4} = 0.75[/tex]

Thus Jason needs to ride 0.75 miles more to reach the end of the path

Answer:DE and BC

Step-by-step explanation:

The equation for line perpendicular to y = -3x - 2 and passing through the point (9,7)  in slope intercept form is:

[tex]y = \frac{x}{3}+4[/tex]

Solution:

Given that we have to write the equation for line perpendicular to y = -3x - 2 and passing through the point (9,7)

Let us first find the slope of line

The equation of line in slope intercept form is given as:

y = mx + c -------- eqn 1

Where, "m" is the slope of line and "c" is the y - intercept

Given equation of line is:

y = -3x - 2

On comparing the above equation with eqn 1

m = -3

We know that product of slope of a line and line perpendicular to it is equal to -1

Therefore,

[tex]-3 \times \text{ slope of line perpendicular to given line } = -1\\\\\text{ slope of line perpendicular to given line } = \frac{1}{3}[/tex]

Now find the equation of line passing through the point (9, 7)

[tex]\text{Substitute } (x, y) = (9, 7) \text{ and } m = \frac{1}{3} \text{ in eqn 1 }[/tex]

[tex]7 = \frac{1}{3} \times 9+c\\\\7=3+c\\\\c = 4[/tex]

[tex]\text{Substitute } m = \frac{1}{3} \text{ and } c = 4 \text{ in eqn 1 }[/tex]

[tex]y = \frac{1}{3}x+4\\\\y = \frac{x}{3}+4[/tex]

Thus the equation of line in slope intercept form is found

Answer:

x = -5

Step-by-step explanation:

8x+32=1/5(25x−15)−4x

8x + 32 = 5x - 3 - 4x

8x + 32 = x - 3

7x = -35

x = -5

Answer:

x = -5

Step-by-step explanation:

Let's expand the parentheses on the right side first:

(1/5) * (25x - 15) = (1/5) * 25x - (1/5) * 15 = 5x - 3

Now put this back in:

8x + 32 = 5x - 3 - 4x

Move all the x terms to one side and all the constants to one side:

8x - 5x + 4x = -3 - 32

Combine like terms:

7x = -35

Divide both sides by 7:

x = -35/7 = -5

Thus, the answer is -5.

Sarah bought 4 first class tickets and 4 coach tickets for a total of 8 tickets, using her entire budget of $5080.

Sarah purchased tickets for a total of 8 people with a mix of coach and first class tickets. The cost for coach tickets was $290 each, and the cost for first class tickets was $980 each. With a total airfare budget of $5080, we need to determine how many of each type of ticket she bought.

Let's denote the number of first class tickets as x and the number of coach tickets as y. The two equations representing the situation are:

From the first equation, we can express y in terms of x: y = 8 - x. Substituting this into the second equation gives us:

980x + 290(8 - x) = 5080

Solving for x will give us the number of first class tickets, and using the value of x, we can find y, the number of coach tickets. After simplifying and solving, we find that:

980x + 2320 - 290x = 5080

690x = 2760

x = 4

Thus, Sarah bought 4 first class tickets. To find the number of coach tickets (y), we substitute x into the first equation:

y = 8 - 4

y = 4

Therefore, Sarah also bought 4 coach tickets.

Step-by-step explanation:

we know that    

The compound interest formula is equal to  

[tex]A=P(1+\frac{r}{n})^{nt}[/tex]  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  

n is the number of times interest is compounded per year

in this problem we have  

[tex]t=?\ years\\P=\$200\\A=\$500\\ r=1.98\%=1.98/100=0.0198\\n=4[/tex]  

substitute in the formula above

[tex]500=200(1+\frac{0.0198}{4})^{4t}[/tex]  

[tex]2.5=(1.00495)^{4t}[/tex]  

Apply property of exponents

[tex]2.5=[(1.00495)^{4}]^t[/tex]  

Apply log both sides

[tex]log(2.5)=log[(1.00495)^{4}]^t[/tex]  

[tex]t=log(2.5)/log[(1.00495)^{4}][/tex]  

[tex]t=46.4\ years[/tex]

Final answer:

To find when the investment of $200 at a 1.98% annual interest rate compounded quarterly will reach $500, we use the compound interest formula and solve for t, representing time in years.

Explanation:

The subject is Mathematics, specifically focusing on the concept of compound interest. To find out when the investment will reach $500, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(nt)[/tex]

Where:
A = the amount of money accumulated after n years, including interest.
P = the principal amount (the initial amount of money).
r = the annual interest rate (decimal).
n = the number of times that interest is compounded per year.
t = the time the money is invested for in years.

In the case of the student's question:

P = $200

n = 4 (since the interest is compounded quarterly)

A = $500

We rearrange the formula to solve for t:

t = (log(A/P)) / (n×log(1+r/n))

Substitute the given values:

t = (log(500/200)) / (4×log(1+0.0198/4))

Use a calculator to compute t, which will give us the number of years it takes for the investment to reach $500.

Answer:

cos θ = -(√3)/2

tan θ = -1/√3

Step-by-step explanation:

[tex]\frac{\pi }{2} <\theta <\pi \ \ \ sin \ \theta = \frac{1}{2} \\[/tex]

Part A: find cos θ:

Using Pythagorean identity

sin²θ + cos²θ = 1

cos²θ = 1 - sin²θ = 1 - (1/2)² = 1 - 1/4 = 3/4

cos θ = ±√(3/4) = ±(√3)/2

∵(π/2) < θ < π  ⇒ ∴ cos θ = -(√3)/2

Part B: find tan θ:

sec θ = 1/(cos θ) = -2/√3

Using Pythagorean identity

tan²θ + 1 = sec²θ

tan²θ = sec²θ - 1 = 4/3 - 1 = 1/3

tan θ = ±√(1/3) = ± 1/√3

∵(π/2) < θ < π  ⇒ ∴ tan θ = -1/√3

Answer:

5 years

Step-by-step explanation:

We are given;

We are required to determine the time taken for the value of the car to depreciate to half the original value.

Therefore;

$6,250 = $12,500(1 - r/100)^n

0.5 = (1 - 13/100)^n

0.5 = 0.87^n

Introducing log on both sides;

log 0.5 = n log 0.87

Therefore;

n = log 0.5 ÷ log 0.87

  = 4.977

  = 5 years

Therefore, it takes 5 years for the value of the car to depreciate to half the initial value.

0.75/0.125 = 6

6 x 0.125 would add up to be 0.75

To divide decimals, move the decimal point in both numbers to turn the divisor into a whole number. Multiply both numbers by the same power of 10 to get rid of the decimals. Then, divide the resulting whole numbers to get the answer.

To divide decimals, we can move the decimal point in both numbers to turn the divisor into a whole number. In this case, we can multiply both numbers by 1000 to get rid of the decimals. So, 0.75 becomes 750 and 0.125 becomes 125. Now, we can divide 750 by 125 to get the answer. Therefore, 0.75 divided by 0.125 is equal to 6.
