Answer:

Slope (m) =

ΔY

ΔX

= 0.25

θ =

arctan( ΔY ) + 180°

ΔX

= 194.03624346793°

ΔX = 1 – 5 = -4

ΔY = 2 – 3 = -1

Distance (d) = √ΔX2 + ΔY2 = √17 = 4.1231056256177

Equation of the line:

y = 0.25x + 1.75

y =

1 x

+ 7

When x=0, y = 1.75

When y=0, x = -7

Three more than twice the sum of a number and half the number equals 105. Which equation models this relationship?

AlekseyPX

Answer:2(x+1/2x)+3=105

Step-by-step explanation: that is how i got my answer. If not a similar answer i would go with 2x+3=3x+105.

You can automatically eliminate the first answer. The second one has a random 5, so eliminated. and the last one just isn't correct.

£70 is divided between Natasha, Richard & Stephen so that Natasha gets twice as much as Richard, and Richard gets three time

Mekhanik [1.2K]

Answer:

£42

Step-by-step explanation:

The ratio of Richard's amount to Stephen's amount is ...

R : S = 3 : 1

The ratio of Natasha's amount to Richard's amount is ...

N : R = 2 : 1 = 6 : 3

Then the ratio of all three amounts is ...

N : R : S = 6 : 3 : 1

The proportion of the total that Natasha gets is ...

6/(6+3+1) = 6/10

so she gets ...

(6/10)×£70 = £42

Natasha gets £42.

Last month, when Joe took his puppy to the veterinarian, the puppy weighed 5.4 pounds. This month, the puppy weighed 7.56 pounds

tino4ka555 [31]

Answer:

40%

Step-by-step explanation:

We are given that last month, Joe's puppy weight 5.4 pounds while this month, the puppy weighed 7.56 pounds.

We are to find the percentage increase of the weight of the puppy

We know that the formula of percentage increase if given by:

Percentage increase = (new value - initial value)/initial value × 100

So substituting the given values to get:

Percentage increase in puppy's weight = $\frac{7.56-5.4}{5.4} \times 100$ = 40%
