The value of the sum of 0.74 and 0.19 is 0.93 and there are 9-tenths in the sum.
What is sum?A summation, also known as a sum, is the outcome of adding two or more numbers or quantities. There are always an even number of terms in a summation. There could be only two terms, or there could be one hundred, a thousand, or a million.
Given:
Add 0.74 and 0.19,
Write the above phrase in mathematical form as shown below,
0.74 + 0.19
convert this into fractions as shown below,
74 / 100 + 19 / 100
Here the denominator is the same, so add the numerator,
(74 + 19) / 100

A shipping container will be used to transport several 130-kilogram crates across the
country by rail. The greatest weight that can be loaded into the container is 26500
kilograms. Other shipments weighing 11400 kilograms have already been loaded into
the container. What is the greatest number of 130-kilogram crates that can be loaded
into the shipping container?
Answer:
Thebecks u
Step-by-step explanation:
its 93
The greatest number of 130-kilogram crates that can be loaded into the shipping container is 116.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
The weight that can be loaded on the container
= Total weight capacity of container - Weight that is already present on the container
= 26,500 kilograms - 11,400 kilograms
= 15,100 kilograms
Now, the number of crates that can be put in the container,
Number of crates
= Weight that can be loaded on the container / Weight of a crate
= 15,100 kilograms / 130 kilograms
= 116.1538 ≈ 116
Hence, the greatest number of 130-kilogram crates that can be loaded into the shipping container is 116.

Grandma made an apple pie. Josh and his brother Joe ate most of it and had 1/5 of it left. Then, three friends came over and shared the leftover pie. How much of the pie did each friend eat?
Answer:
1/15
Step-by-step explanation:
Total pie = x
Total pie left = 1/5x
Then, three friends came over and shared the leftover pie
How much of the pie did each friend eat?
Pie eaten by each of the three friends = leftover pie / 3 friends
= 1/5x ÷ 3
= 1/5x * 1/3
= 1/15x
Each of the three friends ate 1/15 of the pie

Trigonometric Ratios
The ratios of the sides of a right triangle are called trigonometric ratios.
The longest side of the triangle is called the hypotenuse and the other two sides are the legs.
The sine ratio is defined as:
[tex]\displaystyle \sin\theta=\frac{\text{opposite leg}}{\text{hypotenuse}}[/tex]
It's required to calculate the sine of angle C. The opposite leg to angle C is 16 and the hypotenuse is 20, thus:

Helen spent 7.75 to purchase 23 snack sized bags of chips (c) and pretzels (p). Chips cost 0.25 and pretzels cost 0.50. How much of each type of snack did she get?
Answer:
15 chips and 8 pretzels
Step-by-step explanation:
According to the problem, calculation of the given data are as follows,
Total spent = $7.75
Number of snacks = 23
Chips cost = $0.25
Pretzels cost = $0.50
Let number of chips = X
So, number of pretzels = 23 - X
So, we can calculate number of snacks by using following equation
0.25X + 0.50 ( 23 - X) = $7.75
0.25X + 11.50 - 0.50X = 7.75
0.25X - 0.50X = 7.75 - 11.5
-0.25X = -3.75
X = -3.75 ÷ -0.25 = 15
Hence, Number of chips = 15
Number of Pretzels = 23 - 15 = 8

The table shows the relationship between the diameter in kilometers of an oil spill and the time in days. A quadratic function can be used to model this relationship.
What is the best prediction of the time required for the oil spill to reach the diameter of 10 km?
A) 147 days
B) 200 days
C) 205 days
D) 233 days
Answer:
205 is my answerrrrrrrrrrr
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 147 days. Then the correct option is A.
What is a quadratic equation?The quadratic equation is given as ax² + bx + c = y. Then the degree of the equation will be 2.
The table shows the connection between the width in kilometers of an oil slick and the time in days. A capability can be utilized to show this relationship.
The equation at (2.4, 1) will be given as,
2.4 = a (1)² + b (1) + c
2.4 = a + b + c ...1
The equation at (9.4, 2) will be given as,
9.4= a (2)² + b (2) + c
9.4 = 4a + 2b + c ...2
The equation at (21.1, 3) will be given as,
21.1 = a (3)² + b (3) + c
21.1 = 9a + 3b + c ...
Solve equations 1, 2, and 3 with the calculator, then we have
a = 2.35, b = -0.05, c = 0.1
Then the equation is given as,
y = 2.35x² - 0.05x + 0.1
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be
y = 2.35(10)² - 0.05(10) + 0.1
y = 235 - 0.5 + 0.1
y = 235.5
The value of y is nearer to the value of 233. Then the value of y will be 233 days.
The best prediction of the time required for the oil spill to reach a diameter of 10 km will be 233 days. Then the correct option is D.
