Alexxx [7]

Answer:Least common multiple (LCM) of 3 and 4 is 12. Least common multiple or lowest common denominator (lcd) can be calculated in two way; with the LCM formula calculation of greatest common factor (GCF), or multiplying the prime factors with the highest exponent factor. Least Common Multiple of 3 and 4 with GCF Formula.

Describe a sequence of transformations that exhibits the similarity between the pair of figures shown.

kow [346]

Answer:

Reflection across the x-axis followed by dilation by a scale factor of $\frac{1}{4}$ with the center of dilation at the origin

Step-by-step explanation:

Rectangle EFGD has vertices at points E(-6,8), F(0,8), G(0,1) and D(-6,1).

1 transformation - reflection across the x-axis with the rule

$(x,y)\rightarrow (x,-y)$

So, the image rectangle E''F''G''D'' has vertices with coordinates

$E(-6,8)\rightarrow E''(-6,-8);$
$F(0,8)\rightarrow F''(0,-8);$
$G(0,1)\rightarrow G''(0,-1);$
$D(-6,1)\rightarrow D''(-6,-1).$

2 transformation - dilation by a scale factor of $\frac{1}{4}$ with the center of dilation at the origin. This transformation has the rule

$(x,y)\rightarrow (\frac{1}{4}x,\frac{1}{4}y)$

Thus,

$E''(-6,-8)\rightarrow E'(-\frac{3}{2},-2);$
$F''(0,-8)\rightarrow F'(0,-2);$
$G''(0,-1)\rightarrow G'(0,-\frac{1}{4});$
$D''(-6,-1)\rightarrow D'(-\frac{3}{2},-\frac{1}{4}).$

These are exactly vertices of rectangle E'F'G'D'.

Mindy is driving 32mi / h as she nears an elementary school. A first grade student runs into the street after a soccer ball, and

kifflom [539]

Answer:

11 meters is her approximate reaction distance.

Step-by-step explanation:

Speed of the car of Mindy = 32 mile/hour = $\frac{32\times 1609.34 m}{3600 s}$

1 mile = 1609.34 m

1 hour = 3600 seconds

Duration for her reaction last after student runs into street in front of her = $\frac{3}{4} seconds$

Distance covered three -quarters of a second = d

$d=\frac{32\times 1609.34 m}{3600 s}\times \frac{3}{4} s$

d = 10.73 m ≈ 11 m

11 meters is her approximate reaction distance.

The average temperature for 5 days was 100 degrees, and then it was cold for 1 day. That brought the average down to 90 degrees

Alona [7]

Answer:

40

Step-by-step explanation:

5 days temperature = 100

So the temperature have to add to 500

6 days temperature = 90

500 + ? = 540

?=40
