4 0

Answer:

1/2

Step-by-step explanation:

The slope of the points (4,-3) and (3,-1) is -2

The slope of a line perpendicular to said points would be the opposite reciprocal which would be 1/2

heres how you'd find the initial slope of the points

(4, -3)

-1  +2

(3, -1)

Slope= rise/run= 2/-1= -2

Sue wants to plan a meal with 71 grams of fat and 1755 calories. If hot dogs have 13 grams of fat and 145 calories each and if b
Lena [83]

Answer:

Sue must use 3 hotdogs and 4 half-cup serving of baked beans.

Step-by-step explanation:

Let the number of hot dogs be represented by h

Let the number of baked beans be represented by b

Hot dogs have 13 grams of fat and 145 calories each

Baked beans have 8 grams of fat and 330 calories per half cup serving

Sue wants to plan a meal with 71 grams of fat and 1755 calories.

Grams of Fat from Hotdog + grams of fat from baked beans=71

13h+8b=71....(I)

Similarly,

Calories from hot dog + Calories from baked beans=1755

145h+330b=1755....(II)

We then solve Equations (I) and (II) simultaneously.

13h+8b=71....(I)

145h+330b=1755....(II)

Multiply equation 1 by 145 and equation 2 by 13

1885h+1160b=10295

1885h+4290b=22815

Subtracting

-3130b=-12520

b=4

Substitute b=4 into (I)

13h+(8X4)=71

13h=71-32

13h=39

h=3

Sue must use 3 hotdogs and 4 half-cup serving of baked beans.

The diameter of a circle is 10 kilometers. What is the circle's radius?<br> d=10 km
alexandr402 [8]

Step-by-step explanation:

Let diameter of the circle be d and radius be r.

\therefore \: r =  \frac{d}{2}  \\  \\   \therefore \: r =  \frac{10}{2}  \\  \\ \therefore \: r = 5 \: kilometers.

Hence radius of the circle is 5 kilometers.

Find the value of x. Round your answer to the nearest tenth.
BlackZzzverrR [31]

Answer:

10.39 or 10.4

Step-by-step explanation:

Since this is a right triangle, you have the formula a squared +b squared = c squared where a and b are the legs and c is the hypotenuse. You plug in the values and you should get sqrt of 108 for x.
