Answer:

x=1.75 hour

Step-by-step explanation:

200km=2.5

140km=x

2.5 * 140=200x

350=200x

x=350/200

x=1.75

the time it will take is x=1.75 hour

The sum of the three interior angles of a triangle is 180°. Suppose one angle is 68° and the remaining two angles are the same m

disa [49]

Answer: 56 degree

Step-by-Step Explanation:

Let measure of unknown angle be ‘x’

One angle = 68 degree
Sum of all angles is 180 => 68 + 2x = 180

Therefore,
68 + 2x = 180
2x = 180 - 68
2x = 112
x = 112/2
=> x = 56

Therefore, the measure of the missing angles is 56 degrees each.

Answer:

12 pencils

Step-by-step explanation:

let no. of pencils bought be x.

54 - 0.75x - 2.50 = 42.50

9 = 0.75x

x = 12

determina la medida de cada uno de los angulos del triángulo ABC si se conoce que (3x+1)° (3x+4)° y (2x-1)°

Triss [41]

Answer:

∠A=67°

∠B=70°

∠C=43°

Step-by-step explanation:

The correct question in English is

Determines the measurement of each of the angles of the triangle ABC if it is known that A=(3x+1)°,B=(3x+4)° and C=(2x-1)°.

we know that

The measure of the interior angles in a triangle must be equal to 180 degrees

∠A+∠B+∠C=180°

substitute the given values

$(3x+1)\°+(3x+4)\°+(2x-1)\°=180\°$

solve for x

$(8x+4)\°=180\°$

$8x=180-4$

$x=22$

Find the measure of each angle

∠A=(3(22)+1)=67°

∠B=(3(22)+4)=70°

∠C=(2(22)-1)=43°

Which statement is best supported by the dot plot? Choose ONE and explain your

maksim [4K]

Answer:

The statement that is best supported by the dot-plot is iii)

The mode of the number of miles Amanda skated in July is equal to the

mode of the number of miles skated in August.

This is a true statement.

The mode of the number of miles Amanda skated in July is equal to 1.

The mode of the number of miles Amanda skated in August is equal.

Step-by-step explanation:

i) The range of the number of miles Amanda skated in August is less than the

range of the number of miles she skated in July.

This is a true statement.

the range of the number of miles Amanda skated in August is 1 to 3

the range of the number of miles Amanda skated in July is 1 to 4

ii) The distribution of data is approximately symmetrical in both sets of data.

This is NOT a true statement.

the distribution of data of the number of miles Amanda skated in August

is not symmetrical.

the distribution of data of the number of miles Amanda skated in August

is approximately symmetrical.

iii) The mode of the number of miles Amanda skated in July is equal to the

mode of the number of miles skated in August.

This is a true statement.

The mode of the number of miles Amanda skated in July is equal to 1.

The mode of the number of miles Amanda skated in August is equal.
