Answer: Sylvia should use 35 pounds of Kona coffee and 65 pounds of Columbian coffee
Step-by-step explanation:
Let x represent the number of pounds of Kona coffee that Sylvia should use.
Let y represent the number of pounds of Columbian coffee that Sylvia should use.
Sylvia wants to mix 100 pounds of Breakfast Blend coffee. This means that
x + y = 100
She is using two types of coffee to create the mixture. Kona coffee sells for $51 per pound and Columbian coffee sells for $11 per pound and the mixture would sell for $25 per pound.
This means that
51x + 11y = 2500 - - - - - - - - 1
Substituting x = 100 - y into equation 1, it becomes
51(100 - y) + 11y = 2500
5100 - 51y + 11y = 2500
- 51y + 11y = 2500 - 5100
- 40y = - 2600
y = - 2600/-40
y = 65
x = 100 - y
x = 100 - 65 = 35
Answer:
The correct option is;
The sum of angles A and B are supplementary to angle C
Step-by-step explanation:
The statements are analysed as follows
1. Angle A is congruent to itself reflective property
Which shows that ΔABC and ΔADE have a common and equal angle
2. Segment ED and CB are parallel
From the transversal line passing EB and CB which shows that the angles ∠ADE and ∠ABC are equal and also ∠AED and ∠ACB are equal
The statement is used to prove similarity between the ΔABC and ΔADE
3. The sum of angles A and B are supplementary to angle C
The above statements relates to only ΔABC and i does not show similarity between ΔABC and ΔADE.
Answer:
45% chance there will be rain tomorrow.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
11:9 odds that there will be no rain
In 11+9 = 20 experiments, in 11 there will be no rain and 9 there will be rain.
Percent change there is rain:
Desired outcomes:
9 experiments(rain)
Total outcomes:
20 experiments
Probability
45% chance there will be rain tomorrow.
0.08 (50h) Is The Tax. The reason I am correct would be: because 0.08 = 8%, and 0.08 * 50h Gives You 8% Of 50h.
10 is the population mean.
The SRS he takes, the simple random sample, is the 60 horses with colic. The population would be all of the horses seen at the clinic. Therefore the mean of the horses seen at the clinic would be the population mean.
