Answer:

40%

Step-by-step explanation:

40%

40*40%= 16

16 is the difference between the 40 and 56.

The percentage increase in the speed of the car from 40 km per hour to 56 km per hour will be 71.43%.

The amount of something is expressed as if it is a part of the total which is a hundred. The ratio can be expressed as a fraction of 100. The word percent means per 100. It is represented by the symbol ‘%’.

A car is travelling at 40 kilometres per hour.

The car increases its speed to 56 kilometres per hour.

Then the percentage increase in the speed of the car will be

[tex]\rm P = \dfrac{40}{56} \times 100\\\\P = 71.4285\% \approx 71.43\%[/tex]

Answer:

A. Bracelets take 3 minutes, and necklaces take 8 minutes.

Step-by-step explanation:

If Mary made 3 necklaces at that rate, it would add up to 24 minutes. A bracelet takes 3 minutes to make, and she made 2, so that would take 6 minutes. Add 24 to 6 and you'll get 30 minutes. I hope this helped :^)

Step-by-step explanation:

yt

Answer:

y=6x-4

Step-by-step explanation:

The equation of line in the slope intercept form is y = 6x - 8 , where the slope of the line is m = 6

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

Let the slope of the line m = 6

Let the y intercept of the line be = -8

Now , equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

Substituting the values in the equation , we get

y = 6x - 8   be equation (1)

Hence , the equation of line is y = 6x - 8

Given

8 total balls

Added up

Probability of 2 same colored balls is 13/28

Based on the amount that you bid and its percentage out of what you would pay, the amount that you were willing to pay more was $15

The winning bid of $35 is only 70% of what you would have paid at most.

Your maximum bid would therefore have been:

= 35 / 70%

= $50

The amount that you were then willing to pay more than your bid was:

= Maximum bid - Winning bid

= 50 - 35

= $15

In conclusion, you were willing to pay $15 more.

Answer:

2.2

Step-by-step explanation:

the equation was not the only way that could change in a single year of growth

we have:(x, y1)=(1,0)

(x2,y2)=(0,1)

then the equation of circle is

(x-1)(x-x2)+(y-y1)(y-y2)=0

=(x-1)(x-0)+(y-0)(y-1)=0

=x2-x+y2-y=0

=x2++y2-x-y=0.

Hence this is the answer.

Step-by-step explanation:

you do 984.20-381.80=602.4

then divide 602.4 by 1/4

which 1/4=25.

then you get $24.09

Answer:

Step-by-step explanation:

984.20-381.80= 602.40

602.40 left in savings.

602.40*1/4= 150.60 transfer to checking account.

602.40-150.60= 451.80 left in the savings account.

Answer:

st=pq su=rp and for the other ones angle q is 75 degrees so just add 59 and 75 then subtract it from 180 because that's how many degrees is in a triangle and angle s is 59

[tex]\huge\underline{\overline{\mid{\bold{\red{ANSWER}}\mid}}}[/tex]

Both triangles are congruent, Hence Angles of both triangle will be equal,

We have got two angles,

LP = 59°, LT = 75°

let the third angle be x

The sum of all angles of a triangle is 180°

So,

59° + 75° + x = 180

x = 46°

a) ST = 8m

b) SU = 7m

c) mLR = 75°

d) mLQ = 46°

e) mLS = 59°

Answer:

3a^2 - 6b + 2ab

Step-by-step explanation:

Put all the like terms together

(4a^2 - a^2) - (7b + b) + 2ab

then simplify

(4a^2 - a^2) = 3a^2

(-7b + b) = -6b

then rewrite

3a^2 - 6b + 2ab

Answer:

3a^2 - 6b + 2ab

Step-by-step explanation:

Add like terms together so shifting the equation a little to make it easier to add:

4a^2 - 7b + 2ab - a^2 + b

4a^2 - a^2 - 7b + b + 2ab

3a^2 - 6b + 2ab

The curve is y = sqrt{x}.

Replace x in the curve with 1 and then with 4 to find your point.

y = sqrt{1}

y = 1

First point (1, 1).

y = sqrt{4}

y = 2

Second point (4, 2).

The equation is [tex]L + B = \$800[/tex]

Andrea will donate $200 for business scholarships and $600 for liberal arts scholarships.

Step-by-step explanation:

Given

Represent Liberal Arts with L and Business with B

From the question, we have that:

[tex]L = 3 * B[/tex]

and

[tex]Total = \$800[/tex]

Required

Determine how much she donates for each

The total L + B is 800

i.e.

[tex]L + B = \$800[/tex]

Substitute 3 * B for L

[tex]3 * B + B = \$800[/tex]

[tex]3 B + B = \$800[/tex]

[tex]4B = \$800[/tex]

Solve for B

[tex]B =\$800/4[/tex]

[tex]B =\$200[/tex]

Recall that :

[tex]L = 3 * B[/tex]

[tex]L = 3 * \$200[/tex]

[tex]L = \$600[/tex]
