Which equation has the correct sign on the product?
A. (-9)(-9) = -81
B. (-12)(4) = 48
C. (31)(-10) = -310
D. (26)(3) = -78
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
A. (-9)(-9) = -81
negative times a negative is a positive incorrect sign
B. (-12)(4) = 48
negative times a positive is a negative incorrect sign
C. (31)(-10) = -310
positive times a negative is a negative correct sign
D. (26)(3) = -78
positive times a positive is a positive incorrect sign
Answer:
C. (31)(-10) = -310
Step-by-step explanation:
This equation has the correct sign, because multiplying a positive number and negative number gives you a negative number.
The other answer choices have the wrong signs.
Multiplying 2 negatives together gives a positive, so A is wrong.
Multiplying a negative by a positive gives a negative, so B is wrong as well.
D is wrong because multiplying 2 positive numbers gives a positive number.
So, C is correct.
Use the Distributive Property to simplify the expression.
1/4(8+x+4)
Answer:
3=1/4x
Step-by-step explanation:
1/4(8+x+4)
=2+1/4x+1
=3+1/4x
The expression after simplification will be 3+x/4
What is Distributive Property?According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
Given an expression, 1/4(8+x+4)
Solving by using Distributive Property,
= 1/4 × 8 + 1/4 × x +1/4 × 4
= 2 + x/4 + 1
= 3 + x/4
Hence, the expression after simplification will be 3+x/4

can someone help me please.
Answer:
Yellow = 2/3(Blue)
Step-by-step explanation:
You only really need the first row of the table since it shows the volume of yellow to the volume of blue.
Before we write the equation we have to find the ratio and to do that we divide.
Divide the amount of yellow by the amount of blue:
3.5/ 5.25 = 0.666 = 2/3
now we can write the eqaution:
Yellow = 2/3(Blue)
If Sara ran 34 km in 300 minutes, what was her speed in km/hr?
Answer:
6.8 km/hr
Step-by-step explanation:
If Sara ran 34 km in 300 minutes, then, in one hour, she would run
=> 34 : 300
=> ? : 60
=> 300 / 5 : 34 / 5
=> 60 : 6.8
So, if she travels 6.8 km in 60 minutes, her speed is 6.8 km/hr

Answer:
1/5 divided by 1/10 is 15. The friend's error was that they did not keep, change, and flip. They did 1 divided by 1 which equals 1, and then 5 divided by 10 which equals 50. This is what gave them 1/50.

Step-by-step explanation:
The common difference, d, is 3, because the number of squares goes up by 3 each time.
d = 3
Number of squares in nth figure is:
a(n) = 4 + d(n - 1)
4 is the initial number of squares, d is how many it goes up each time, and we take n-1 because you need to account for the initial number of squares.
a(n) = 4 + d(n - 1)
For n = 200
a(n) = 4 + d(n - 1)
a(200) = 4 + 3(200-1)
a(200) = 4 + 3(199)
a(200) = 4 + 597
a(200) = 601
Compare the decimal numbers 0.896 and 0.689.

0.689 = 0.896
Answer:
0.896 > 0.689
explanation: 0.689 is less than 0.896 because the tenths place depends on how close it is to one. And 0.8 is more than 0.6.

Raul is performing an experiment. He pours water into a glass and measures the temperature of the water at 72.3°F. Then he adds a few ice cubes to the glass of water. He measures the temperature of the water again and finds that it has changed by -39.1°F.
Simplify the expression in (-30) + 70 + (-9) + 2 +(-0.1) + 0.3 = 2 + (-9) + 70 + (-0.1) + 0.3 + 70
Answer:
When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.
Step-by-step explanation:
Answer:
[70 + (-30)] + [2 +(-9)] + [0.3 + (-0.1)]
=
40 + (-7) + 0.2
=
33 + 0.2
=
33.2°F
The temperature of the water dropped to 33.2°F after Raul added the ice cubes.
