Yes, because she can do 120 in four minutes and in one minute she can do 30 and 120 plus 30 is i fifty

Jake makes 9 loaves of olive bread. he uses 30 grams of olives in each loaf. he started with 1 kilogram of olives. how many gram

dmitriy555 [2]

Jake started with an initial amount of 1 kg of olives or 1000 grams.

He made 9 loaves of olive bread and each bread requires 30 grams of olive, therefore total amount of olives used is:

9 * 30 grams = 270 grams

Therefore Jakes is left with:

<span>1000 grams – 270 grams = 730 grams</span>

Unsure of what i need to do for question 1 and 2

AfilCa [17]

Answer:

f(1)=0; f(0)= -2; f(-1)=(-4); f(2)=2

Step-by-step explanation:

For the first four questions, f(1) means that x= 1, so you need to look at the graph, find the point where x= 1, and find the corresponding y value which is 0. You do this same process for each of the rest.

For 5 and 6: when they say f(x) = some value, this is the y value. So look at the graph: when y = 4, you can see that x = 3. When y = -6, you can see that x= -2.

The following set of random numbers represents 20 simulations of three daily

babunello [35]

The number of simulations in which was there was an on-time departure for all three flights is; 6

<h3>How to carry out number simulations?</h3>

We are given;

Number of Simulations = 20

Numbers that represent late departure = 0, 1, 2 or 3

Numbers that represent On-time departure = 4, 5, 6, 7, 8 or 9.

Now, the 20 simulations as seen online are;

339 931 317 444 432 858 194 192 649 709

742 626 702 258 955 880 505 854 774 132

To know the number of simulations that were on-time departure, we need to find the ones that don't include 0, 1, 2 or 3.

Looking at the simulations, the ones that represent on-time departure are 444, 858, 649, 955, 854, 774.

Thus, there are 6 simulations in which was there an on-time departure for all three flights

SOMEONE CAN HELP ME , PLEASE I NEED THIS NOW

Rudik [331]

You have 2 shapes, a rectangle and a half circle.

Area of rectangle = 3 x 8 = 24

Area of a half circle = 1/2 x pi x r^2

Area of half circle = 1/2 x 3.14 x 4^2

Area of half circle = 25.12

Total area = 24 + 25.12 = 49.12 square units
