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 true statement is: -1.9 > -6.0
Let the second car meets the first car after n hours.
Second car starts with 8km/h, After succeeding hours his speed increases by 0.5 km.
So, Distance travelled by second car = 8 + 8.5 + 9
..... 8+(n-1) 0.5.....(1)
eqn. (1) sum of n terms Of A.P with first term 8
and common difference 0.5.
Sum of all the terms in equation 1 is also equals to the distance travelled by the first car for n hours, i.e. 10n km .
Now, we have (n/2) {16+(n-1) 0.5} = 10n........(2)
From equation (2) we get, n= 9
Hence, Both the cars will meet after 9 hours.
Hope it helps!
The answer is b. 777777777777( dont mind the 7's)
I believe D). 5 is the answer. If you clearly think about it, it actually might make sense. You just count the lines pointing from up to down.
