Erin calculated the average speed of her most recent run to be 120/16 miles per hour how is this friction expressed as a decimal

Contact [7]

Answer:

$\dfrac{15}{2}$

Step-by-step explanation:

The average speed of the Erin is 120/16 mph

Here,

Numerator = 120

Denominator = 16

mph = miles per hour

We need to find an expression expressed as a decimal.

So,

$\dfrac{120}{16}=\dfrac{2\times 3\times 2\times 2\times 5}{2\times 2\times 2\times 2}\\\\=\dfrac{15}{2}$

So, the final answer is $\dfrac{15}{2}$ .

Plz Help ASAP!

Part A:

From the graph, it seems that the lines intersect at (3,-1)... This seems to be the solution...

Part B:
g(x) is a negative line, and the slope is 2 (from rise/run). Y int. = 5. So, the equation is -2x+5. Plug in some numbers for this; say 1 and 2. The coordinates would be (1,3) and (2,1).

Part C:
The 2 graphs seem to intersect at (0,5), so this is the solution...

ALL of this is based on only looking at the graph, which is no better than drawing lines on the sand.. For example, the y intercept for g(x) could be 4.9 or 5.1, and I don't know the equation for f(x)... Based on the info I have, gave my best answers..

Hope this helps..

Julie used her gift card for the local coffee shop to buy iced teas for herself and five friends. After she and one friend place

valentina_108 [34]

Answer:

One glass of iced tea cost $2.72

Step-by-step explanation:

Let,

x be the amount of gift card.

y be the amount of one glass of iced tea.

According to given statement;

Julie and her friend bought tea and remaining balance was $14.85

x - 2y = $14.85 Eqn 1

All the six members bought tea and remaining balance was $3.97

x - 6y = $3.97 Eqn 2

Subtracting Eqn 2 from Eqn 1

$(x-2y)-(x-6y)=14.85-3.97\\x-2y-x+6y=10.88\\4y=10.88$

Dividing both sides by 4

$\frac{4y}{4}=\frac{10.88}{4}\\y=2.72$

Hence,

One glass of iced tea cost $2.72

ASAP help and explain plz

Since x is across from 148, and arcs opposite inscribed angles = 2×angle, then we can find x first.
We could set the 2 angles equal to 180 or their arcs equal to 360.
360 - (2×148) = x-arc
x-arc = 360 - 296 = 64
x = x-arc ÷2 = 64/2 = 32
Now for angle A we plug in for x:
A = 2x+1 = 2(32)+1 = 65°
