I'm pretty sure that's just asking what 9x457 is, and that's 4,113.

2hours at 30km/h 7 hours at 65 km/h 1/2 hours at 46 km/h 45 minutes at 80 km/h 1 1/2 hours at 55km/h fors numbers 1-5, calculate

N76 [4]

Answer:

60 km

455 km

23 km

60 km

82.5 km

Step-by-step explanation:

Time = t

Speed = s

Distance is given by

$d=s\times t$

t = 2 hours

s = 30 km/h

$d=30\times 2=60\ \text{km}$

Distance driven is 60 km.

t = 7 hours

s = 65 km/h

$d=65\times 7=455\ \text{km}$

Distance driven is 455 km

t = $\dfrac{1}{2}\ \text{hours}=0.5\ \text{hours}$

s = 46 km/h

$d=46\times 0.5=23\ \text{km}$

Distance driven is 23 km

t = 45 minutes = $\dfrac{45}{60}=0.75\ \text{hours}$

s = 80 km/h

$d=80\times 0.75=60\ \text{km}$

Distance driven is 60 km

t = $1\dfrac{1}{2}\ \text{hours}=1.5\ \text{hours}$

s = 55 km/h

$d=55\times 1.5=82.5\ \text{km}$

The distance driven is 82.5 km

If a data set has 20 data values, the number of values in the upper quartile is .

tresset_1 [31]

Sample Response: First, Allan should write the fractions as decimals by dividing the numerator by the denominator. Then he can plot the points on the number line. Reading the plotted points from left to right gives the points in order, from least to greatest.

Consider the equation below

s344n2d4d5 [400]

Answer: B

Step-by-step explanation:

Let's solve the given equation. Then we can see which other equation has the same answer.

-5n+31=-14n-5

36=-9n

n=-4

We need to fina another equation that gives n=4 as the answer.

A. Incorrect

3-6n+3n=-3+4-4n

3-3n=1-4n

n=-2

B. Correct

$\frac{11}{4} n+2=-3+\frac{3}{2}n$

$\frac{5}{4}n=-5$

$n=-4$

C. Incorrect

1=0.75n+3.25

-2.25=0.75n

n=-3

D. Incorrect

-1-22n=-20n-9

8=2n

n=4
