Answer:
90kg
Step-by-step explanation:
it is so because, to decrease a number by a ratio you have to multiply with the smallest number and divide with the biggest one. For example 117 in the ratio 7:3. 117×3=351 which is divided by 7 and is equal to 50.14.
The value 117kg decreased in the ratio 10:13 will be 90kg
Ratios and proportionGiven the ratio 10:13. To reduce 117kg in this ratio, we will follow the steps:
Step 1: Multiply 117 by the smallest value
117 * 10 = 1170
Step 2: Divide the result by the largest value to have:
Value = 1170/13
Value = 90kg
Hence the value 117kg decreased in the ratio 10:13 will be 90kg

Frozen chickens will be sold by a major chain of supermarkets only if their weight
is at least 1.2 kg and not more than 3.4
kg.
(a) Represent this information on a number line.
Write an inequality to describe this.
Answer:
In the number line it should be between 1.2 and 3.4
intervals of 0.2
for e.g: 3.4 3.2 3.0 2.8 2.6 2.4 2.2 2.0 1.8 1.6 1.4 1.2
Step-by-step explanation:
Assume chicken to be x
1.2 [tex]\leq[/tex] x < 3.4
Inequality shows a relationship between two numbers or two expressions.
The inequality to describe the chicken that can be sold only when the chicken weighs between 1.2 kg to 3.4 kg is
1.2 ≤ x ≤ 3.4
Where x is the number of chicken.
What is inequality?It shows a relationship between two numbers or two expressions.
There are commonly used four inequalities:
Less than = <
Greater than = >
Less than and equal = ≤
Greater than and equal = ≥
Example:
2 < 3
3x > 2x
3x + 4 > 4x
We have,
Number of chickens that can be sold = x
Chicken is sold only if the chicken weighs between 1.2 kg and 3.4 kg.
This can be represented by inequality as,
1.2 ≤ x ≤ 3.4
Thus,
The inequality to describe the chicken that can be sold only when the chicken weighs between 1.2 kg to 3.4 kg is

What is the volume of the cargo area of the moving truck?
A. 696 cubic feet
B. 756 cubic feet
C. 824 cubic feet
D. 888 cubic feet
Answer:
888sq. ft
Step-by-step explanation:
Volume of a rectangular prism = length * width * height
For the given diagram
area of the truck = area of the bigger + area of smaller prism
area of the bigger prism = 6 * 9 * 16
area of the bigger prism = 864sq. ft
Area of smaller prism = 2 * 2 * 6
Area of smaller prism = 24 sq. ft
Area of the figure = 864 + 24
Area of the figure = 888sq. ft

Answer:
1/14
Step-by-step explanation:
According to SOH CAH TOA;
Cos theta = adjacent/hypotenuse
Since theta = <J
Adjacent = 2
Hypotenuse = 28
Cos <J = adj/hyp
Cos<J = 2/28
Cos<J = 1/14
Hence the value of cosine J is 1/14
