Answer:

1. 31.14

2. 46

Step-by-step explanation:

1. Using order of operations, we first simplify what's in the parentheses, so we do 4.1-(-6.2), or 4.1+6.2. This gives us -5+3.8(10.3). Next is multiplication, so we do 3.8(10.3), which gets us to -5+39.14. Lastly, we add, to get 31.14.

2. First, we solve in the parentheses. Within the parentheses, we do multiplication first, so we first do 3*-2, to get us 8-4(-6+(-13))÷2. Then, we solve inside the parentheses, so we do -6+(-13), to get 8-4(-19) ÷2.

Next, since multiplication and division are on the same level, we go from left to right, so we do -4*-19 first, to get 8+76÷2. Now we do division, to get 8+38. Lastly, we add, to get 46.

Compute using significant digits. What is the area of a parallelogram with length 17.25 mm and width 5.065 mm?
Dmitriy789 [7]

Answer: Option 'a' is correct

Step-by-step explanation:

Since we have given that

Length of parallelogram =17.25 mm

Width of parallelogram =5.065 mm

As we know the formula for " Area of parallelogram"

Area of parallelogram is given by

Area= length \times breadth\\\\17.25\times 5.065=87.03 \   mm^2

Hence, option 'a' is correct .

Evaluate each expression for g = -7 and h = 3 and match it to its value. 1. g + h 2 2. g - h 46 3. h - g -21 4. gh -4 5. g + h2
Ivanshal [37]

Answer:

1. -4

2. -10

3. 13

4. -21

5. 2

6. 46

Step-by-step explanation:

To evaluate the expression, substitute g= -7 and h = 3. Then simplify using order of operations.

1.  g-h = -7 + 3 = -4

2. g-h = -7 - 3 = -10

3. h-g = 3 - -7 = 3+10 = 13

4.gh = -7(3) = -21

5. g+h^2 = -7 + 3^2 = -7+9 = 2

6. g^2-h = (-7)^2 -3 = 49 -3 = 46
