Answer:

True speed of the car is 87 km/h.

Step-by-step explanation:

Speed = 100 km/h

hike in speed = 25 %

Let the true speed is v.

[tex]v + 15% of v = 100 \\\\v + 0.15 v = 100 \\\\1.5 v = 100\\\\ v = 87 km/h[/tex]

Answer:

Answer B as the difference between the values is the same

Answer:

The perimeter is 36.2 units.

Step-by-step explanation:

M (4,4), N (5,-7) and O (-6,-6)

The distance formula is

[tex]d =\sqrt{(x''-x')^2 + (y''-y')^2}\\\\MN =\sqrt{(5 -4)^2 + (- 7 - 4)^2}\\\\MN = 11.05 \\\\MO =\sqrt{(-6 -4)^2 + (- 6 - 4)^2}\\\\MO = 14.14\\\\ON =\sqrt{(-6-5)^2 + (- 6 + 7)^2}\\\\ON = 11.05[/tex]

The perimeter is given by

P = MN + NO + MO

P  = 11.05 + 14.14 + 11.05 = 36.24 units

Answer:

Y = 2/3x-8/3

Step-by-step explanation:

y − 4 = 2/3 ( x − 3)

y − 4 = 2/3x -2

y  = 2/3x +2

~~~~~~~~~~~~~~~~~

-2 = 2/3(1) + b

b = -2 2/3 = -8/3

Answer:

The total charge with the discount is $182

The refund is $78

Step-by-step explanation:

Given data

Charge= $260

Discount=30%

Let us find the amount of the 30%

=30/100*260

=0.3*260

=$78

The new charge after the discount is

=260-78

=$182

The total charge with the discount is $182

The refund is $78

Answer:

two

Step-by-step explanation:

The number of solutions is the number of times the graphs intersect.

The line and the parabola intersect two times, so there are two solutions

Answer:

a=2

b=10.5

c=4

d=17.5

Step-by-step explanation:

so 3.5 miles per hour and the columns are miles and then hours

so an equation can be 3.5 (mi/hr) * t (time) = distance

so for a): 3.5*t=7

t=2

b) 3.5*3=distance

distance is 10.5

c) 3.5*t=14

t=4

d) 3.5*5=d

d= 17.5

Answer:

x-8

Step-by-step explanation:

since we dont know how much gas is in the tank, lets make that X.

and since we subtract 8 gallons from how much is in the tank, we make that X-8

Answer:

Inequality:

x < 8

The Graph Would be the Hallow Dot on the 8,  then it would go the left way.

Answer:

Four times 3 less than the number is 6 more than the number.

Step-by-step explanation:

4(x - 3 ) => four times  3 less than the number

x + 6 => 6 more than the number.

4(x - 3 ) = 6 + x  => four times 3 less than the is 6 more

                             than the number.

Answer:

Step 1: Put the numbers in order.

1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.

Step 2: Find the median.

1, 2, 5, 6, 7, 9, 12, 15, 18, 19, 27.

Step 3: Place parentheses around the numbers above and below the median.

Not necessary statistically, but it makes Q1 and Q3 easier to spot.

(1, 2, 5, 6, 7), 9, (12, 15, 18, 19, 27).

Step 4: Find Q1 and Q3

Think of Q1 as a median in the lower half of the data and think of Q3 as a median for the upper half of data.

(1, 2, 5, 6, 7), 9, ( 12, 15, 18, 19, 27). Q1 = 5 and Q3 = 18.

Step 5: Subtract Q1 from Q3 to find the interquartile range.

18 – 5 = 13.

Answer:

Q1 : Ruppell's Giffrons

Q2 :

sperm whales

dolphins

missing birds

Ruppell's Giffrons

Step-by-step explanation:

I don't know if I can see the full picture, as it is clearly cut off.

my answers are based on what I can see :

Giffrons, migrating birds, dolphin and sperm whale.

here are the reasons for my 2 answers :

sea level = elevation of 0 ft. so, this is "point" 0.

Q1 now asks about what of the listed animals can move the farthest away from 0.

and distance is always positive. now matter the direction we are going. if we go from 0 to +5, the distance is 5. and if we go from 0 to -5, the distance is also 5.

so, we are looking for the animal with the largest absolute value of elevation it can reach.

and that are the Ruppell's Giffrons with 37000 ft. 37000 is much farther away from 0 than e.g -3000. and so on.

Q2 wants us to sort the animals based on their reachable elevations.

by the way, the correct words would be "lowest to highest". as this is how elevation works on scales.

and remember, negative values get actually larger in their absolute values, when we make them smaller.

-2 is smaller than -1.

therefore, the animal that can get the lowest of all here is the sperm whale.

then comes the dolphin.

then the migration birds.

and then the Ruppell's Giffrons.

The Brown Spider Monkey can travel at the greatest distance from sea level compared to the other mentioned animals. The order of elevations from least to greatest would be Blue Whale, Mountain Lion, Mountain Goat, and Brown Spider Monkey.

The animal that can travel at the greatest distance from sea level is the Brown Spider Monkey. It is found in the tropical rainforests of South America and can live at elevations of up to 9,000 feet (2,700 meters) above sea level. The other animals mentioned, Mountain Goat, Blue Whale, and Mountain Lion, are all restricted to lower elevations.

In terms of elevations from least to greatest, the order would be:

Blue Whale - Lives in the ocean at sea level

Mountain Lion - Found in various habitats including mountains and plains

Mountain Goat - Lives in mountainous regions

Brown Spider Monkey - Found in the tropical rainforests at high elevations

[tex]m\angle F\approx 100^{\circ}[/tex]

Step-by-step explanation:

For any triangle, the Law of Cosines is given by [tex]c^2=a^2+b^2-2ab\cos C[/tex], where all three variables are interchangeable.

Therefore, we have:

[tex]f^2=g^2+h^2-2gh\cos F,\\960^2=380^2+820^2-2(380)(820)\cos F,\\\cos F=-\frac{131}{779},\\F=\arccos(-\frac{131}{779})\approx \boxed{100^{\circ}}[/tex]
