4.13

Step-by-step explanation:

good luck

Answer:

x = 3, y = 5

Step-by-step explanation:

Since the ordered pairs are equal, then equate the x and y coordinates

x + 2 = 5 ( subtract 2 from both sides )

x = 3

y - 1 = 4 ( add 1 to both sides )

y = 5

Answer: 28.8%

Step-by-step explanation:

First find out what her speed is:

Speed = Distance / Time

= 50 / 45

= 1.11 meters/second

Now her speed is:

= 50 / 35

= 1.43 meters/ second

The percentage increase in her speed is:

= (New speed - Old speed) / Old speed

= (1.43 - 1.11) / 1.11

= 0.288

= 28.8%

Answer:

4

Step-by-step explanation:

50/5+2-[3+9]-3+7

=10+2-12-3+7

=12-12-3+7

=-3+7

=4

Answer:

the correct answer is 4

Step-by-step explanation:

first your going to calculate the parentheses

[3+9]=12

which leaves the equastion as

50/5+2-12-3+7

then multiply and divide going left-right

50/5=10

which makes the equastion

10+2-12-3+7

then add and subtract going left to right so it would be

10+2=12-12=0-3=-3+7=4

Answer:

(c) The triangles are similar, so the sides are proportional:  DE = BC. Therefore, the slope of AD is the same as the slope  of AB

Step-by-step explanation:

Given

See attachment for proper format of question

Required

Why is the slope between A and D the same

From the question, we understand that:

[tex]\triangle ADE[/tex] and [tex]\triangle ABC[/tex] are similar

This implies that similar sides are proportional.

i.e.

[tex]AD \to AB[/tex]

[tex]AE \to AC[/tex]

[tex]DE \to BC[/tex]

Slope (m) is calculated as:

[tex]m = \frac{Rise}{Run}[/tex]

So, the slope of [tex]\triangle ADE[/tex] is:

[tex]m = \frac{DE}{AE}[/tex]

Slope of [tex]\triangle ABC[/tex] is:

[tex]m = \frac{BC}{AC}[/tex]

Since the triangles are similar, then:

[tex]m = m[/tex]

i.e.

[tex]\frac{DE}{AE} = \frac{BC}{AC}[/tex]

Hence, (c) is true

Answer:

Slope: 3, Y-intercept: 8

Step-by-step explanation:

=> Slope: Change in y / Change in x

Change in y = +6

Change in x = +2

Slope = 6 / 2

Slope = 3

=> A value of y in the data set where x = 0

Y-intercept: 8

Answer:

≈ 18.8 cm

Step-by-step explanation:

The arc length is calculated as

arc = circumference of circle × fraction of circle

The central angle is equal to the arc subtending it, that is 60°

  arc = 2πr × [tex]\frac{60}{360}[/tex]

        = 2π × 18 × [tex]\frac{1}{6}[/tex]

        = 36π × [tex]\frac{1}{6}[/tex]

        = 6π ≈ 18.8 cm ( to 1 dec. place )

Answer:

x=5.886 , x=1.614

Step-by-step explanation:

Given data

2w^2 - 15w + 19 = 0

a= 2

b= -15

c= 19

The expression for the Quadratic Formula is

x=(-b±√(b²-4ac))/(2a)

substitute

x=(-(-15)±√((-15)²-4*2*19))/(2*2)

x=(15±√225-152))/(4)

x=(15±√73))/(4)

x=(15±8.544))/(4)

x=(15+8.544))/(4) , x=(15-8.544))/(4)

x=23.544/4 , x=6.456/4

x=5.886 , x=1.614

Answer:

67%

Step-by-step explanation:

Let the percentage of the first solution = x

7 gallons + 4 gallons = 11 gallons

Our system of equation is

Seven gallons of a sugar solution was mixed with 4 gallons of a 80 percent sugar solution to make an 72 percent sugar solution.

7 gallons × x % + 4 gallons × 80% = 72% × 11 gallons

= 7x + 3.2 = 7.92

Collect like terms

7x = 7.92 - 3.2

7x = 4.72

x = 4.72/7

x = 0.6742857143

Converting to percentage

0.6742857143 × 100

= 67.42857143%

Approximately, the percent concentration of the first solution is 67%

Answer:

.05 or 1/20

Step-by-step explanation:

If you meant 3/10 divided by 6 then the answer is .05 aka 1/20

May I have brainliest if this helped you?

Hope this helped!!

Bella was here :)

You either meant the fraction 3/10 by 6 or 3 divided 10 divided by 6

Since I am not sure which one, I will do the work for both

1. 3/10 / 6

Convert 6 into a fraction

6 = 5 10/10

5 10/10=50/10

3/10 / 50/10

3/10 * 10/50 = 30/500

30/500= 3/50

3/50

2. 3 divided by 10 divided by 6

3 divided by 10 = 0.3

0.3 divided by 6 = 0.05

0.05

Answer:

you owe $5

Step-by-step explanation:

65% wins means $65

35% losses means -$70

Answer:

You owe 5 cents.

Step-by-step explanation:

(the amount of money won)(the number of successful rolls)+(the amount of money lost)(the number of unsuccessful rolls)=expected value

65% of rolls are successful which means that  13/20 of the rolls are successful (simply convert to a fraction).

35% of the rolls are unsuccessful which means that 7/20 of the rolls are unsuccessful.

Using the equation above we can use,

(1)(13/20)+(-2)(7/20)

to find the expected value.

(1)(13/20)+(-2)(7/20)=0.05

Answer:

[tex]x + y = 5 \\ 5 \times 5 = 25[/tex]

Answer:

The average rate of change is: 0.25

Step-by-step explanation:

Given

See attachment for graph

Required

The average rate of change between 1930 and 1950

Average rate of change (m) is calculated as:

[tex]m = \frac{f(b) - f(a)}{b - a}[/tex]

In this case,

[tex][a,b] = [1930,1950][/tex]

So, we have:

[tex]m = \frac{f(1950) - f(1930)}{1950 - 1930}[/tex]

[tex]m = \frac{f(1950) - f(1930)}{20}[/tex]

From the attached graph;

[tex]f(1950) = 45[/tex]

[tex]f(1930) = 40[/tex]

So, we have:

[tex]m = \frac{45- 40}{20}[/tex]

[tex]m = \frac{5}{20}[/tex]

[tex]m = 0.25[/tex]

Answer:

answer: 150 in sq

Step-by-step explanation:

All we have to do to these is multiply 2.5 by the base and height then multiply base × height so 2.5 × 8 = 20 2.5 × 3 = 7.5

20 × 7.5 = 150 Hope this helps!
