Can someone round this to the nearest tenth
3.14 x 4 x 4 x 7
or
3.14 x 7 x 7 x 4
A- 124.6
B- 87.9
C- 97.5
D- 78.9

Answers

Answer 1

Answer:

I think its A

Step-by-step explanation:

I did the math and thats what i got even rounded up

Answer 2

The value of the expression 3.14 x 4 x 4 x 7 is  351.4 and for expression 3.14 x 7 x 7 x 4  is 615.4.

To round the expression to the nearest tenth, we need to evaluate it first. Let's calculate each expression:

3.14 x 4 x 4 x 7 = 351.36

3.14 x 7 x 7 x 4 = 615.44

Now, let's round each result to the nearest tenth:

Rounding 351.36 to the nearest tenth gives us 351.4

Rounding 615.44 to the nearest tenth gives us 615.4

Based on the given options, neither result matches exactly.

However, option A (124.6) is the closest rounded value to 351.4.

Matthew had to make a bridge for his math class. It had to be at least 1 1/2 feet long. Harold made a bridge that was 2/13 times as long as Matthew’s. Write and solve an equation that will help you figure out how long Harold’s bridge was. Explain the steps you took to solve the problem.

Answers

Answer:

Step-by-step explanation:

2 / 13 = 15.38% or 15.38..... If Matthew's bridge is 1 1/2 feet long which is 45.72cm then 45.72 + 15.38 = 61.1cm > convert into feet > 1.55194 ft.

Isolate the variable:

4x/4 = 48/4

Simplify:

X=12

Hope this helps!

Answer:

x = 12

Step-by-step explanation:

Step one: Inverse the equation to eliminate the coefficient*.

*The coefficient is the number or variable that multiplies another variable (associated with it). In this case, it is four that is the coefficient.

48/4 = 12

x = 12

Check for answer:

4*12 = 48

The answer is x = 12.

A group of friends is roping off a soccer field in a back yard. A particular full-size soccer field is a rectangle with a length of 100 yards and a width of 50 yards. To fit the field in the back yard, the group needs to reduce the size of the field so its perimeter is 60 yards.
What is the Area of the soccer field in the back yard?

Answers

Answer:

200 ft

The original perimeter would be 300, so divided by 5, it would be 60. 100/5 is 20, 50/5 is 10. 20*10 is 200.

b. 3/8 or 4/9

Answers

Answer:

for a it would be 11/18 and for b it would be 4/9

Step-by-step explanation:

This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.

Two angle measurements of a triangle are 62° and 28°. What is the measurement of the third angle?

Here are your options!
90°, 110°, 10°, 62°

Answers

Answer:

90°

Step-by-step explanation:

the sum of the angle measurements of a triangle always equals 180°

so if you add the 2 you have you would get 90°

then you subtract that from 180°

x= 180°- (62°+ 28°)

Answer:

the third angle would measure 90 degrees

Step-by-step explanation:

the answer is 90 degrees because 62+28=90 and the area of a triangle is 180 degrees so 180-90=90

Answers

Answer:

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

A linear relationship is a relationship with a constant rate of change represented by a graph that forms a straight line that passes through the origin (0, 0) and is represented by y = kx. The rate of change is either positive, negative, zero, or undefined.
