a. You have to just add up the ingredients to find the total cups of ingredients.

So...

1 1/2 + 3/4 + 1/8 = 1 4/8 + 6/8 + 1/8 = 1 11/8 = 2 3/8

b. You can use 3 or 4 cup mixing bowls because their capacity is more than the total cups of ingredients.

the answer is b

X is a bigger number and the difference between x and y is 7, so x-y=7. And it says that the sum of two numbers is 31 so x+y=31

The speed of a car after accelerating for 8 seconds is inversely proportional to its weight. The car weighs 1600 kg and accelera

STatiana [176]

Answer:

With 800 extra kg load: speed = 66.667 km/h

With 2400 extra kg load: speed = 40 km/h

Step-by-step explanation:

Let's call the weight of the car W = 1600 kg, and its speed after accelerating for 8 seconds with this weight S = 100 km/h

If we load the car with 800 extra kg, the total weight will be:

W2 = W + 800 = 2400 kg

The relation between the weights is:

W2 / W = 2400 / 1600 = 1.5

If the weight increased 1.5 times, the relation between the speeds will be 1/1.5 (as they are inversely proportional), so:

S2 / S = 1 / 1.5

S2 = S / 1.5 = 66.667 km/h

If we load the car with 2400 extra kg, the total weight will be:

W3 = W + 2400 = 4000 kg

The relation between the weights is:

W3 / W = 4000 / 1600 = 2.5

If the weight increased 2.5 times, the relation between the speeds will be 1/2.5, so:

S3 / S = 1 / 2.5

S3 = S / 2.5 = 40 km/h

Help <3 ;3

Tomtit [17]

Hello,

Rational numbers are numbers that can be represented by fractions that consist of integers.

In this case, B. -7/3 is already a fraction that consists of integers, so it is a rational number.
C. square 3 is = $3^{2}$ = 9, which can be represented by 9/1, so it is also a rational number.

A and D are incorrect as they cannot be represented by fractions that consist of integers.

The answers are B and C.

Hope this helps!

How to determine if the function has x-axis sym, y-axis sym, and origin sym y^2 -xy =2

n200080 [17]

To check for symmetry on the x axis, replace y with –y

-y^2 –x(-y) =2

Apply the product rule, since the equation is not identical tot eh original equation it is not symmetric about the x axis

Now do the same for y axis by replacing x with –x

Again using product rule the equations are not identical, so it is not symmetric about the y axis

To check the origin,

Replace both x & y with –x & -y

Again using product rule, the equations are not identical so it is not symmetric about the origin
