Answer:

x = √29

Step-by-step explanation:

25 + 4 = c^2

29 = c^2

√29 = √c^2

√29 = c

Answer: 65°

Step-by-step explanation: We are assuming that these lines are ║.

If two parallel lines are cut by a transversal,

then alternate interior angles are congruent.

Since x and 65 lie on alternate side of the transversal and

on the interior of the two lines, we know that x = 65.

Answer:

27/70

Step-by-step explanation:

This is simple: First, you multiply the numerators. 3x9 is 27. That is the numerator to your answer.

Next, you multiply the denominators. 7x10 is 70. That's the denominator to the answer.

Put them together and you get 27/70.

Answer:

x = 6 lb

Step-by-step explanation:

Let

Total weight of the candy = x

3/20x + 1.2 lb + 3/5x + 0.3 lb = x

3/20x + 3/5x + 1.5 lb = x

3x+12x/20 + 1.5 lb = x

15/20x + 1.5 = x

1.5 = x - 15/20x

1.5 =20x -15x /20

1.5 = 5/20x

1.5 = 1/4x

x = 1.5 ÷ 1/4

= 1.5 × 4/1

= 6

x = 6 lb

Step-by-step explanation:

x/y=constant

12/4=3

x/1=3

x=3

Here, if x varies directly as y. When y=1, then x=3.

Given that, x varies directly as y.

Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. Proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.

If x= 12 when y= 4

Here, x varies directly as y is x∝y

⇒ x=ky

⇒ 12=k(4)

⇒ k=3

So, x=3y

When y=1, we have

x=3(1)

⇒ x=3

Here, if x varies directly as y. When y=1, then x=3.

Points scored by Adam, Bethany and Charles are 25, 17 and 30 respectively.

Algebra is a study of mathematical expressions, in which numbers and quantities are represented in formulas and equations by letters and other universal symbols.

Given that,

Adam scored 8 more points than Charles,

And Bethany scored 5 more points than Adam.

Also, total score is 72.

Let points scored by Adam is x,

Then point scored by Charles = x-8,

And point scored by Bethany = x+5.

Since, total score = 72

x + x-8 + x+5 = 72

3x - 3 = 72

3x = 75

x = 25

Points scored by Adam is x = 25,

Point scored by Charles = x-8 = 17,

And point scored by Bethany = x+5 = 30.

Answer:

The missing sides are 50 inches and 48 inches long.

Step-by-step explanation:

Let the lengths of the other two sides be x inches and y inches

And let x represent the length of the longest side.

From the question,

The difference between the lengths of the other two sides is 2 inches. That is,

x - y = 2 ...... (1)

The three sides of the right triangle are x, y, and 14 inches long.

From the Pythagorean theorem, " In a right triangle, the square of the longest side equals sum of squares of the other two sides"

Here, the longest side is x

Hence, we can write that

x² = y² + 14²

∴ x² = y² + 196 ...... (2)

Now, we have two equations, we can then solve simultaneously.

From equation (1)

x - y = 2

∴ x = y + 2 ...... (3)

Put this into equation (2)

x² = y² + 196

(y+2)² = y² + 196

y² + 4y + 4 = y² + 196

4y + 4 = 196

4y = 196 - 4

4y = 192

y = 192/4

y = 48

To determine x, we will substitute the value of y into equation (3)

x = y + 2

∴ x = 48 + 2

x = 50

Hence, x = 50 and y = 48

Since the lengths of the other two sides are x inches and y inches,

Hence, the missing sides are 50 inches and 48 inches.

12 is its average rate of change from x = 2 to x = 10.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

Given the function defined by y = x^2

now,

its average rate of change from x = 2 to x = 10,=

=10^2-2^2/10-2

Answer:

Calories from both fat and carbohydrates = 900 calories/day

Step-by-step explanation:

Number of calories eaten by Sandra per day = 2000 calories/day

Calories from fat = [tex]\frac{1}{4}[/tex] of the total number of calories per day

OR

Calories from fat = [tex]\frac{1}{4}\times 2000 = 500\ calories/day[/tex]

Calories from carbohydrates = [tex]\frac{1}{5}[/tex] of the total number of calories per day

OR

Calories from carbohydrates = [tex]\frac{1}{5}\times 2000 = 400\ calories/day[/tex]

To find the total number of calories from both fat and carbohydrates, we need to add the calories from fat and calories from carbohydrates as calculated above.

Calories from both fat and carbohydrates = Calories from fat + Calories from carbohydrates = 500 + 400 = 900 calories/day

Step-by-step explanation:

by minusing the both values it'll be 240

The rate at which the storage space of the mobile gets filled by the movie is - 60 MB per minute.

Given that,
A student buys a movie to watch on her phone
it will download at a constant rate.
After 3 minutes, she checks her phone and sees that she has 2,345 MB of space available.
She checks her phone after 7 minutes and notices that she now has 2,105 MB of space available.

The rate of change is defined as the change in value with the rest of the time is called rate of change.

Here,

Rate = (storage available after 3 minutes) - (storage available after 7 min)]
             ---------------------------------------------------------------------------------------------
                                              Time interval

Rate = (2,345 - 2105 ) / (3 - 7)
Rate = - 240 / - 4
Rate = - 60

Where negative sign shows that the amount of storage getting reduced.

Thus, the rate at which the storage space of the mobile gets filled by the movie is - 60 MB per minute.
