If 2 bags of chips cost $1.50, 1 bag of chip costs half that price.

construction = divide the figure into two parts.

now we have triangle abd and bdc.

first calculate the area of abd.

area of triangle= 1/2×base ×height

area of triangle= 1/2×18×7.5

area of triangle=67.5cm²

second calculate area of bdc

area of triangle=1/2×15.6×11.7

area of triangle=91.26cm²

area of the figure=area of abd + area of bdc

area of the figure=67.5cm²+ 91.26cm²

area of figure=158.76 cm².

Answer:

104

Explanation:

1. Split the figure by the line the larger portion creates.

2. Calculate the area of the left-hand side... 7 · 8 = 56cm squared.

3. You know that the total length of the figure is 15cm. You've already "used" 7cm of that. So... 15 - 7 = 8.

4. Now, we simply do 6 · 8 = 48. Almost there!

5. Finally, add the values of the left side and the right side (48 + 56 = 104)

6. YOUR ANSWER IS 104 cm squared.

Answer:

Step-by-step explanation:

Let's solve your system by substitution.

5x+3y=35;2x+4y=28

Step: Solve 5x+3y=35 for x:

5x+3y=35

5x+3y+−3y=35+−3y(Add -3y to both sides)

5x=−3y+35

5x/ 5 = −3y+35/ 5  (Divide both sides by 5)

Step: Substitute  −3/ 5 y+7 for x in 2x+4y=28:

2x+4y=28

2( −3/ 5 y+7)+4y=28

14/ 5 y+14=28   (Simplify both sides of the equation)

14/ 5 y+14+−14=28+−14   (Add -14 to both sides)

14/ 5 y=14

14/ 5 y/ 14/ 5 = 14/ 14/ 5

(Divide both sides by 14/5)

y=5

Step: Substitute 5 for y in x= −3/ 5 y+7:

x= −3/ 5 y+7

x= −3/ 5 (5)+7

x=4  (Simplify both sides of the equation)

Answer:

x=4 and y=5

Answer:

Equation 2: x - 2y = 1

Step-by-step explanation:

The equations easiest to use substitution are the ones that have the variable multiplied by one, as in the case of Eq. 2 where x is 1x, so if you substitute a zero for x, we know that y has to be -1/2 for the equation to be true.  Furthermore, if you substitute a 0 for y you automatically know that x = 1.

If you try to substitute anything for x in equation 1, let's say x = 1, you still have to multipy by 3, then the rest of the problem would be more steps.

Answer: The computer worth $ 492.38 after 5 years.

Step-by-step explanation:

If the value of an item depreciates by r% then the value of the item after t years is given by :-

[tex]V=V_0(1-\dfrac{r}{100})^{t}[/tex]

, where [tex]V_0[/tex] = initial value.

Given: [tex]V_0[/tex] =$1,250, r=17% , t= 5 years

Then, the value of computer after 5 years = [tex]1250(1-\dfrac{17}{100})^5[/tex]

[tex]=1250(0.83)^5\\\\=1250(0.39390)\\\\\approx492.38[/tex]

Hence, the computer worth $ 492.38 after 5 years.

Slope- intercept form       y = 200 x + 500

Step-by-step explanation:

Explanation:-

Given that the equation

        200x - y + 500 = 0

where   y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours

The slope-intercept form

                 y = m x +C

Given equation  200x - y + 500 = 0

                           200 x + 500 =y

                        y = 200 x + 500

Slope of the equation m = 200 and y-intercept 'C' = 500

Answer:

0.753

Step-by-step explanation:

I just took the test lol

The value of log₃(⁷/₁₆) when log₃4 = 1.262 and log₃7 = 1.771 is;

log₃(⁷/₁₆) = -0.753

We are given;

log₃4 = 1.262

log₃7 = 1.771

We want to find log₃(⁷/₁₆)

Now, from properties of logarithm too, we have;

logₐ(x/y) = logₐx - logₐy

Thus;  log₃(⁷/₁₆) =  log₃7 -  log₃16

Also, we know that; logₐx² = 2logₐx

Thus; log₃16 =  log₃4²

log₃16 = 2log₃4

Thus; log₃(⁷/₁₆) = log₃7 - 2log₃4

Plugging in the relevant values gives;

1.771 - 2(1.262) = -0.753

Answer:

1. Proportional

2. Not proportional

3. Proportional

Step-by-step explanation:

We have three questions with 2 ratios and are asked if they are proportional or not.

To define proportionality, basically its if the two ratios equal the same value when put in a certain way.

And that way is :

[tex]\frac{x}{y} =\frac{x}{y}[/tex]

You will substitute the numbers with the letters, in which you will cross multiply :

[tex]\frac{x * y}{x*y}[/tex]

So subtitute :

1.

[tex]\frac{1}{3} *\frac{7}{21}[/tex]

[tex]\frac{1*21}{7*3}[/tex]

[tex]21=21[/tex]

Therefore 1. is proportional.

2.

[tex]\frac{3}{4} *\frac{24}{18}[/tex]

[tex]\frac{4*24}{3*18}[/tex]

[tex]\frac{96}{54}[/tex]

96 = 54

Therefore 2. is not proportional.

3.

[tex]\frac{1}{5} *\frac{6}{30}[/tex]

[tex]\frac{1*30}{5*6}[/tex]

[tex]\frac{30}{30}[/tex]

30 = 30

Therefore 3. is proportional.

Answer: 10

Step-by-step explanation:

To find a common denominator, simply multiply the denominator and numerator of one fraction by the denominator and numerator of the other.  Then repeat.

3*2/5*2 = 6/10

1*5/2*5=5/10

As you can see, the denominator of both fractions is 10.

Answer:

71° F

Step-by-step explanation:

Consider the rational part of f(t)

[tex]\frac{40t^3}{t^3+100}[/tex]  ( divide numerator and denominator by t³

= [tex]\frac{40}{1+\frac{100}{t^3} }[/tex]

As t → infinity then [tex]\frac{100}{t^3}[/tex] → 0 , the expression simplifies to

[tex]\frac{40}{1+0}[/tex] = [tex]\frac{40}{1}[/tex] = 40

Thus after driving for a long time

f(t) = 31 + 40 = 71° F
