Answer:
1) 1/23 2) 6/23 3) 2/23 4) 0/23 5) 7/23
Step-by-step explanation:
There are 23 marbles in total.
1) 1/23 There is 1 white marble.
2) 6/23 There are 6 red marbles.
3) 2/23 There are 2 yellow marbles.
4) 0/23 There are 0 purple marbles.
5) 7/23 There are 7 black marbles.
Answer:
Rhombus
Rectangle
Square
Step-by-step explanation:
A parallelogram is a shape of four sides, quadrilateral, that has equal and opposite sides. In this case, the problem is asking to name three kinds of parallelograms to complete the hierarchy.
In the hierarchy, quadrilaterals come first because a quadrilateral is a polygon of four edges, no matter if the sides of the polygon are irregular.
Then comes the parallelograms that are quadrilaterals with equal, opposite sides.
And some types of parallelograms are:
Rhombus in which all the sides are equal but the angles are not right angles
Rectangle that has right angles
Square all the sides are equal and it has right angles
The equation is a = 4d and the solution is a = 32. This means that Arthur saves $32 per week.
An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that;
Saving per week= $8
Now,
To write an equation that shows how to find the amount “a” Arthur saves, we need to use the given information. We are told that Arthur saves 4 times the amount D’ John saves in the same week.
We can write this as:
a = 4d
where a is the amount Arthur saves and d is the amount D’John saves. We are also told that D’John saves $8 per week. We can substitute this value into the equation and solve for a. We get:
a = 4d a = 4(8) a = 32
Therefore, by the equation the answer will be a = 4d, a = 32 and Arthur saves $32 per week.
