Shade the model to show the decimal 0.542 using 100 grid and 10 grid
kherson [118]

0.542=0.500 + 0.040+0.002

          = \frac{5}{10} + \frac{4}{100} +\frac{2}{1000}

         =5 tenth + 4 hundredths + two thousandths

One tenth = \frac{1}{10}

One Hundredth= \frac{1}{100}

Three houses are mapped on a coordinate grid.
Licemer1 [7]

Step-by-step explanation:

Let us consider the task to find the angle between vectors ES and EJ (the first letters are taken to name the vectors).

\overrightarrow{ES} = (4;4) - (4; -3) = \overrightarrow{(0; 7)}

ES

=(4;4)−(4;−3)=

(0;7)

​

\overrightarrow{EJ} = (-5; -4) - (4; -3) = \overrightarrow{(-9; -1)}

EJ

=(−5;−4)−(4;−3)=

(−9;−1)

​

cos \alpha=\frac{\overrightarrow{ES}*\overrightarrow{EJ}}{|\overrightarrow{EJ}|*|\overrightarrow{ES}|}cosα=

∣

EJ

∣∗∣

ES

∣

ES

∗

EJ

​

cos(a) = (0*(-9)+7*(-1)) / (7*9.055) = -0.11043;

a = 96,34°

Solution: 96 degrees.

Jake drove 66 miles in 2/5 hour. what's the unit rate in miles per hour?
Ad libitum [116K]

Answer:

He was going about 26 miles an hour.

Step-by-step explanation:

This is a fraction equal to

66 miles ÷ 2.5 hours

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 2.5

66 miles ÷ 2.5

2.5 hours ÷ 2.5

=

26.4 miles

1 hour

=

26.4 miles

hour

= 26.4 miles per hour
