Share 120 hours in the ratio 5:7.
When 120 hours shared in the ratio it gives 50 hours : 70 hours
Lets add up the ratio= 5 + 7 =12
Now for 5/12 of the time = 5/12 × 120
= 50 hours
And for 7/12 of the time = 7/12 × 120
= 70 hours
What is ratio?A ratio in mathematics describes the amount of times one number is present in another. For instance, the proportion of oranges to lemons in a bowl of fruit is eight to six if there are eight oranges and six lemons (that is, 8:6, which is equivalent to the ratio 4:3). The proportions of oranges to the overall amount of fruit are 8:14 for oranges and 6:8 (or 3:4) for lemons (or 4:7).
The quantities in a ratio can be of any form, including counts of people or things, measures of lengths, weights, or times, etc. Both numbers must be positive in the vast majority of situations.

The water level of a river was measured each day during a two-week period. The graph models the linear relationship between the water level of the river in feet and the number of days the water level was measured. Which statement best describes the y-intercept of the graph?
Answer:
c
Step-by-step explanation:
The y-intercept of a graph is the point where the graph touches the y-axis.
The best describes the y-intercept of the graph is (a) the initial water level of the river is 16 ft
From the attached graph, we observe that the graph crosses the y-axis at y = 16
This value represents the initial value of the graph.
In other words, the initial water level of the river
So, the y-intercept means that:
The initial water level of the river is 16 ft
Hence, the true statement is (a)

Answer:
1,7
Step-by-step explanation:
7x = 9x-2
2 = 2x
x = 1
y = 7
Answer:
(1,7)
Step-by-step explanation:
okay, since the equations are both equal to y we can set the equations to be equal to each other and solve for x
9x - 2 = 7x
subtract 9x from both sides
-2 = -2x
divide both sides by -2
x = 1
now that we have the x-value we can plug it back in to get a y-value
y = 7x
y = 7(1)
y = 7

Doz of egg is $0.85
5 lb of flour is $1.95
5 lb of sugar is $2.05
3 lb of shortening is $3.35
To find the cost of the ingredients of 1 pt (2cup) milk, 4 eggs, 2 lb (4cup) flour, 1 lb (2cup) sugar and 1 lb shortening
1 gallon = 8pt, then half gallon is 4pt
4 pt of milk cost is $2.12
Then cost of 1 pt of milk cost, 2.12/4 = $0.53
Total cost of ingredients is $0.53+ $0.283+ $0.78+ $0.41+ $1.1167 = $3.1197

What do you mean by shortening?
Any fat that is solid at room temperature and used to create flaky pastry and other foods are known as shortening.
Long before the creation of contemporary, shelf-stable vegetable shortening, the concept of shortening may be traced back to at least the 18th century.
Lard was the main component used to shorten dough in past eras. It behaves as though it has short fibers, which is why it is termed shortening since it makes the finished dish crumbly.
