If the two smaller numbers equal the biggest number, it can't be a triangle. The two sides have to be bigger than the bigger side
a) 6 cm, 6 cm , 12cm 6 + 6 = 12. N0 TRIANGLE
b) 19 cm, 27 cm, 10cm. 19 + 10 = 29 YESS TRIANGLE
c) 3cm, 7cm, 19cm 3 + 7 = 10 N0 TRIANGLE
d) 20ft, 10ft, 5ft 10 + 5 = 15 N0 TRIANGLE

THE ANSWER IS B

The answer of the second problem is B) 29cm since 10 + 17 = 27 and it has to be a bigger number

What is the measure of AC?

Mama L [17]

Answer:

The answer would be 12

Step-by-step explanation

The answer would be 12 because the meter is calibrated to display 12 when it gets that 5 V signal internally and the range is set to AC. ... You don't say if you are measuring a battery or a power supply and if you are using a digital meter or a small analogue one.

Police use the formula [math]v=2 \sqrt{5 L}[/math] to estimate the speed of a car, v, in miles per hour, based on the length, L,

Len [333]

Answer:

$V(L=45) = 2\sqrt{5*45ft}= 2 \sqrt{225}= 2*15 =30 \frac{mi}{hr}$

And if we compare this value with the speed limit of 35 mi/h then the police officer should believe that the motorist was not speeding, since his speed was lower than 35 mi/hr.

Step-by-step explanation:

Estimate the speed at which the motorist was traveling before braking

For this case we have the following formula for the spped of a car:

$V= 2 \sqrt{5L}$

Where L represent the length and v the velocity in miles/hr.

For this case we know that a police officer measures the car’s skid marks to be 45 feet long, so then L =45 ft, and we can finde the velocity of the car replacing L=45 ft and we got:

$V(L=45) = 2\sqrt{5*45ft}= 2 \sqrt{225}= 2*15 =30 \frac{mi}{hr}$

If the posted speed limit is 35 miles per hour and the motorist tells the officer she was not speeding, should the officer believe her? Explain

And if we compare this value with the speed limit of 35 mi/h then the police officer should believe that the motorist was not speeding, since his speed was lower than 35 mi/hr.

the population of South Africa is four times the population of Greece. if the population of south Africa is 44 million, write an

bixtya [17]

From the problem statement, the population of South Africa is four times the population of Greece.

The population of Greece is 11 million

<em>Given data</em>

Population of South Africa is 44 million,

Let the population of Greece be x

Hence the population of South Africa will be = 4*x

Hence the expression becomes

44million = 4x

Let us divide both side by 4 to find the population of Greece

x= 44million/4

x = 11 million

Hence the population of Greece is 11 million
