Answer:

4 servings

Step-by-step explanation:

Yogurt in the container = 1 5/8 pounds

A serving = 3/8 pounds

how many servings of yogurt are in the container?

Servings in the yogurt container = total yogurt in the container / yogurt per servings

= 1 5/8 ÷ 3/8

= 13/8 × 8/3

= 13/3

= 4.33

To the nearest whole serving

= 4 servings

Step-by-step explanation:

Hey there!

By looking at the figure, the given "2x" and "6x + 28" are co-interior angle.

So,

2x + 6x + 28 = 180°. ( sum of co-interior angle is 180°)

8x + 28°=180°

8x = 180° - 28°

8x = 152°

[tex]x = \frac{152}{8} [/tex]

X = 19°

Therefore, X = 19°.

Hope it helps...

Answer:

x=19

Step-by-step explanation:

These are same-side interior angles. The Same-Side Interior Angles Theorem states that if two parallel lines are cut by a transversal, then the same side interior angles are supplementary. This means that the sum of the two angles is equal to 180°.

2x+6x+28=180°

8x=180-28

8x=152

x=19

Answer:

The correct linear function is c(x) = 5.50 + 20.50x.

Step-by-step explanation:

It's a linear function, so that means it uses y=mx+b. It says "per ticket" which means that the ticket cost is the slope, or m, of the equation. The service fee would be added on as a one-time fee, making it the y-intercept, or b. In order to find the cost of the tickets, you had to subtract the service fee from the total cost, then divide by how many tickets were purchased. You can set this up by plugging in what you know.

[tex]108=5.50+5x[/tex]

Subtract the 5.50 from both sides, leaving us with:

[tex]103.50=5x[/tex]

Now, this equation tells us how much 5 tickets cost, but we want how much it is per ticket. That means now we have to divide both sides by 5:

[tex]20.50=x[/tex]

Thus, one ticket is $20.50.

[tex]c(x)=5.50+20.50x[/tex]

The linear function is c(x) = 5.50x + 20.50

Let the cost of the tickets be represented by x

Therefore, 108 = 5.50 + 5x

Collect like terms

5x = 108 - 5.50

5x = 103.50

Divide both side by 5

5x/5 = 103.50/5

x = 20.50

Therefore, a ticket costs $20.50

In conclusion, the total cost, when x tickets are ordered will be c(x) = 5.50x + 20.50.

Answer:

the expression has three factors

Step-by-step explanation:

(2-7y)(y+15)

2y+30-7y-105

-5y+30-105

The expression (2 – 7)(y + 15) has 1 factor.

A number or algebraic expression that evenly divides another number or expression, i.e., leaves no remainder, is referred to as a factor.

An expression which has the highest power of one of the variable is called one degree or linear polynomial.

The given expression is;

(2 – 7)(y + 15)

As, the expression has variable 'y', which has the highest power of one. It means the expression is a one degree polynomial.

The factor of polynomial is always equal to its degree; here in this case it is one.

Therefore, the expression (2 – 7)(y + 15) has only one factor.

Parallelograms PQRS and QRTU have the same base QR and height. it proves that areas are equal as base × height remains constant.

To prove that the area of parallelograms PQRS and QRTU are equal,

Use the concept that parallelograms with the same base and between the same parallel lines have equal areas.

Parallelograms PQRS and QRTU

Same base QR

Between the same parallel lines PT and QR

Proof,

Draw a diagram with parallelograms PQRS and QRTU sharing the common base QR and being situated between parallel lines PT and QR.

Since PQRS and QRTU share the same base QR and are between the same parallel lines PT and QR, their heights (perpendicular distances from base QR) are equal.

Let's call this height 'h'.

The area of a parallelogram is given by the formula:

Area = base × height.

For PQRS, its area would be: Area of PQRS = QR × h.

For QRTU, its area would be: Area of QRTU = QR × h.

Since both parallelograms have the same base 'QR' and the same height 'h', their areas are equal.

Therefore, it is proved that the area of parallelograms PQRS and QRTU are equal.

Answer: |81-x|<5

Step-by-step explanation:

Given: Temperature of an enclosure for a pet corn snake should be an average of 81° F.

Temperature in the enclosure should not vary by more than 5° F.

Let x= Temperature in the enclosure

Then, difference between average and current temperature should less the 5.

i.e. |81-x|<5     (required absolute value equation  )

hence, the absolute value equation could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure:

|81-x|<5

Using absolute value, it is found that the equation that could be used to determine the minimum and maximum temperatures recommended for the corn snake enclosure is:

[tex]|T - 81| = 5[/tex]

[tex]|x| = x, x \geq 0[/tex]

[tex]|x| = -x, x < 0[/tex]

In this problem, the temperature T should be within 5º F of 81ºF, hence, the absolute value of the difference between T and 81 should be of 5, that is:

[tex]|T - 81| = 5[/tex]
