Answer:

Step-by-step explanation:

It cannot be A or B because you already have both of your angles, and it cannot be C because the sides do not line up. By the process of elimination it will be D.

Answer:

Step-by-step explanation:

AAS = angle angle side

we already have the 2 angles so it cant be A or B. we need to find the equal corresponding side lengths. C is incorrect because side BC is not corresponding to side DF. therefore, it is D. sorry im bad at explaining but i hope this helped :)

A van travels from Town A to Town B. It uses 1 gallon of gas for every 24 miles traveled. A) How many gallons of gas does the va

Setler79 [48]

Answer:

A) $\frac{x}{8}$ gallons

B) Distance between Town A and Town B is $48y$ miles

Step-by-step explanation:

We know, number of gallons = $\frac{DistanceTravelled}{MilesPerGallon}$

if miles per gallon (mpg) is given as 24 & total distance travelled is 3x miles, then, using formula we have:

Number of Gallons = $\frac{DistanceTravelled}{MilesPerGallon}=\frac{3x}{24}=\frac{x}{8}$

Now, given is number of gallons = 2y & we know mpg is 24; <em>so what is the distance?</em>

We use the same formula and solve for distance (let distance between A and B be "D"):

$NumberOfGallons=\frac{DistanceTravelled}{MilesPerGallon}\\2y=\frac{D}{24}\\D=2y*24\\D=48y$

Fifty-five percent of the members of the junior varsity swim team wear glasses. Of the team memebers who do not wear glasses, 30

GarryVolchara [31]

the probability that a randomly chosen member of the JV swim team does not wear glasses and is in the 10th grade is 14%.

Given, the members of the junior varsity swim team wear glasses is 55%.

And the members of junior varsity swim team who do not wear glasses and in 10th grade is 30%.

Let the total no. of members be x.

So, the members of the junior varsity swim team wear glasses (55%),will be

$0.55x$ .

The total number of members not wearing glasses, will be

$x - 0.55 x = 0.45 x$ .

Now, the no. of members not wearing glasses and in 10th grade will be,

$\frac{0.45x\times30}{100} =0.135x$

We know that the probability of an event E, P(E) will be,

$P(E)=\frac{No.\ of Favourable\ outcomes}{total \ no. \ of \ outcomes}$

So, the probability for no. of members not wearing glasses and in 10th grade will be,

$P(E)=\dfrac{0.135x}{x}$

$P(E)=0.135\\\\P(E)=13.5 \%$

Hence the nearest whole percent of probability is 14%.

The slope of the lines that passes through the points (-10,0) and (-13,3)

goldenfox [79]

Answer:

-1

Step-by-step explanation:

The formula to find the slope of a line is:

$\frac{y_{2}- y_{1} }{x_{2} -x_{1} }$

where (x1, y1) and (x2, y2) are points on the line. We can substitute the points (-10, 0) and (-13, 3) into the formula and simplify:

$\frac{3-0}{-13-(-10)} =\frac{3}{-13+10} =\frac{3}{-3} =-1$

This means the slope of the line is -1.

oksano4ka [1.4K]

Answer:

instead of just pointing out the highest speed or one speed, list all the different speeds or increasing/decreasing and the different intervals

ie for minutes 2 to 3, her speed was 30 mph . . . from minutes 6 to 8, her speed was decreasing at a constant rate of -2 mph/min
