Answer:

a=2.55

b=0.576

c=912.87

f=2.295

Step-by-step explanation:

=15/100*17

=2.55

=17/100*15

=2.55

=1.2/100*48

=0.576

=12/100*480

=57.6

=147/100*621

=912.87

=125/100*549

=686.25

=80/100*2.55

=2.04

=40/100*2a

=40/100*(2*2.55)

=0.4*(5.1)

=2.04

=36/100*2.5(2.55)

=0.36*6.375

=2.295

=1.5/100*80(2.55)

=0.015*(204)

=3.06

The high temperature for the day was 5.4°F

Step-by-step explanation:

-18.3 + 23.7= 5.4

The high temperature for the day is 5.4° F.

Temperature is a degree of hotness or coldness the can be measured using a thermometer. It's also a measure of how fast the atoms and molecules of a substance are moving. Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.

Given that, The morning temperature in Finland was -18.3° F.

The temperature rose 23.7° F during the day before reaching its high temperature for the day.

Now, -18.3°+23.7°

= 5.4° F

Therefore, the high temperature for the day is 5.4° F.

Answer:

D.

Step-by-step explanation:

Pretend the y-axis is a wall, on the left side it is decreasing and on the right it is increasing, so A. and B. aren't correct. C. and D. are left, x<0 means on the left side of the y-axis because x (any number) is less than 0 and on the left side it is decreasing so C. isn't correct so D. is your answer because x>0 means x is greater than 0 so it's on the left side of the y-axis.

Answer:

Area of larger circle = [tex]\pi *r^2=3.14(11^2)=379.94[/tex]

Area of smaller circle = [tex]\pi *r^2=3.14(3^2)=28.26[/tex]

Probability that it lands in the shaded area (smaller circle):

28.26 ÷ 379.94 = 0.07438... = 0.07 (nearest hundredth)

The range of a function is the possible output values the function can have.

The range of the function is all real values except 0

The function is given as:

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

When the denominator of the function is 0, the function would not have a real value.

This means that:

[tex]\mathbf{y \ne 0}[/tex]

i.e. the value of y cannot be 0.

Hence, the range of the function is all real values except 0

Step-by-step explanation:

10 choose 3

theres really no simple way to do that with work unless you have a fancy calculator.

Answer:  No

Step-by-step explanation:

The question is whether 3(4x+2) could ever equal 6(2x+2).  So let's set them equal to each other and find if there is a value of x, the days, where they are equal.

3(4x+2) = 6(2x+2)

12x + 6 = 12x+2

6 = 12??  No

They will bnever be at the same height.  They are growing at the same rate (12x) but starting at different heights (6 and 12)

Answer:

a) slope / m = 3

b) y-intercept / b = 0

c) Proportional

Step-by-step explanation:

a)

( y1 - y2 ) / ( x1 - x2 )

( 6 - 12 ) / ( 2 - 4 )

( -6 ) / ( -2 )

6 / 2

3

b)

y = mx + b

6 = 3(2) + b

6 = 6 + b

0 = b

c)

Proportional is when it crosses origin ( 0, 0 ).

Not proportional is when it does not cross origin.

Answer:

121

Step-by-step explanation:

Since the two lines are parallel, they will have the same angles, so all we need to do is find the angle that is next to 59°. Let's label this y °.

In other words, y °, the angle next to 59°, is equal to x°.

Since we are dealing with angles of a straight line, we know that the two angles of either line will add up to be 180°.

So, 59° + y ° = 180°

Isolate y by subtracting 59 from 180.

180 - 59 = 121

y ° = 121

So, x° = 121°

Answer:

x = 3

Step-by-step explanation:

6x - 7y = 4

We are given that y = 2

6x - 7(2) = 4

6x - 14 = 4

Add 14 on both sides to leave the 6x alone

6x = 18

Divide by 6 to isolate x and find the value of x

x = 3

We can further prove this by putting in the value of x

6(3) - 7(2) = 4

18 - 14 = 4

Which is correct
