which number is greater -4.2 or -4.2???. sorry don't have to much points

Answer:

29/10 or 2 9/10

4 4/5 - 1 9/10

make them into improper fractions

4 4/5 = 24/5

1 9/10 = 19/10

24/5 - 19/10 we need to get common denominators

24/5 × 2 = 48/10

48/10-19/10 = 29/10 = 2 9/10

Answer:

The value of x for the point that divides the line segment AB into a ratio of 2:3 is (B) -0.4

Step-by-step explanation:

It is given that we need to find the x value for the point that divides the line segment AB into a ratio of 2:3 from the option given in the question.

Now, let us find the difference between the values of x of point A and of point B;

=> 5 - (-4)

=> 5 + 4

=> 9

Now, let us divide 9 by 5 so that we get the ratio 2:3;

=> 9/5

=> 1.8

Further, for getting the segments as 2 + 3;

=> 1.8 × 2

=> 3.6

and

=> -4 + 3.6

=> -0.4

Therefore, the value of x for the point that divides the line segment AB into a ratio of 2:3 is (B) -0.4

If two of the angles in a scalene triangle are 54° and 87°, the value of the other angle is 39°.

A scalene triangle is a triangle that has three unequal sides.

We have,

Two angles of a scalene triangle are 54° and 87°

We know that,

A scalene triangle has all its three angles different in measures and obeys the angle sum property.

i.e Sum of the three interior angles = 180 degrees.

Let M is the other angle.

M + 54° + 87° = 180°

M = 180 - 141

M = 39°

Thus the value of the other angle is 39°.

No the given two ratios not form a proportion.

Any relationship that has a constant ratio is said to be proportional. For instance, the ratio of proportionality is the average number of apples per tree, and the number of apples in a crop is proportional to the number of trees in the orchard.

Two equivalent fractions are typically used to represent a proportion. For instance: The ratios on either side of the equal sign can be seen in the equation. Because inches and feet are consistent units, each ratio compares the same units, and as a result, all ratios are equivalent. Two quantities are compared to form a ratio. An equality of two ratios is a proportion.

The interest rate of $9000 and $6000 investment are 3.5% and 3% respectively.

let's assume the interest rates X and Y on $9,000 and $6,000 investments.

The $9000 is invested at an interest rate that is 0.5% higher than the $6000.

Therefore,

9000(X) = 6000(Y) + 135

X = Y + 0.005

In canonical form:

9000X - 6000Y = 135

X - Y = 0.005

or X = 0.005 + Y

Then,

9000( 0.005 + Y) - 6000Y = 135

Then Y = 0.3 , therefore X = 0.3

So, X = 3.5% (the rate on $9,000 investment) and;

Y = 3% (the rate on $6,000 investment).

The total volume of the juice in milliliters is 5750ml.

Here, we know that, using unit conversion,

1 liter = 1000 milliliters

Juice contained in Can A is 2.5 liters.

converting it into milliliters,

2 liters = 2 x 1000ml

2 liters = 2000ml

the juice volume becomes 2500ml in Can A.

Juice contained in Can B is 3 liters and 250 milliliters

converting it into milliliters,

3 liters and 250ml = 3 x 1000ml + 250ml

3 liters and 250ml = 3250ml.

the juice volume becomes 3250ml in Can B.

When both Cans are mixed,

Total volume of the juice = volume of juice of can A + volume  juice of can B

Total volume = 2500ml + 3250ml

Total volume = 5750ml.

Answer:

[tex]y=-8[/tex]

Step-by-step explanation:

Recall the slope formula:

[tex]m=\frac{x_{2} -x_{1}}{y_{2} -y_{1}}[/tex]

Since all of the x and y values are -8, we can easily plug in the values.

[tex]m=\frac{-8+8}{-8+8}=0[/tex]

(The second -8 on the top and bottom is positive because adding when subtracting negatives, you must add. For example -1-(-1) would become -1+1=0)

Recall the point-slope formula:

[tex]y-y_{1} = m(x-x_{1} )[/tex]

Now substitute and solve.

[tex]y-(-8)=0(x-(-8)[/tex]     Substitute

The average amount of money spent by students in the cafeteria last week was between $2.25 to $3.25

An equation is used to show the relationship between numbers and variables. An equation can be linear, quadratic depending on the degree.

Let x represent the average amount of money spent by students.

The absolute value inequality is given by the equation:

|x - 2.75| = 0.5

Hence:

x - 2.75 = 0.5 or -(x - 2.75) = 0.5

x = 3.25 or x = 2.25

1) common form of slope-interception form: y=slope*x+interception;

2) if according to the condition slope=4/3, thenthe slope-interception form is y=4/3*x+interception;

3) it is possible to calculate the interception if to substitute given coordinates (-9;-6) into the slope-interception form:
