Answer:

We need 4/5 cups of oil

Step-by-step explanation:

We can use ratios to solve.  Put the amount of oil over the number of batches

2/3  cup          x cups                    

---------------- = --------------

2.5 batches      3 batches

Using cross products

2/3 * 3 = 2.5 *x

2 = 2.5 x

Divide each side by 2.5

2/2.5 = 2.5x/2.5

.8 =x

Changing this back to a fraction

4/5 =x

We need 4/5 cups of oil

Create equivalent fractions:

23/x = 40/17

Cross multiply and divide:

x = 9.8

Answer:

Option D. Segment BC

Step-by-step explanation:

we know that

The external secant is a segment contained by a secant segment with an endpoint on the circle and at the fixed point outside the circle

In this problem

AC is a secant segment and BC is a external secant

EC is a secant segment and DC is a external secant

Without a diagram, an external secant segment is defined as the portion of a secant line that lies outside the circumference of a circle, extending from the point of tangency to another point outside the circle.

An external secant segment is part of a secant line that extends from the point of tangency on the circle's circumference to the point outside the circle where the secant line ends. Without the specific diagram referenced in the question, we can use the given information to assume that segments A, B, C, and D may connect in some way to a circle, since secant lines and segments are defined in relation to circles.

Typically, a secant line will intersect the circle at two points, while an external part of the secant would be the part that lies outside the circle. Given options A. segment EC, B. segment AC, C. segment ED, and D. segment BC, the segment that would qualify as an external secant segment is the one that extends from the circle's edge without entering the circle itself again.

Answer:

c

Step-by-step explanation:

Answer:

y = 7/5x + 18/5

Step-by-step explanation:

so we have y = mx + b

f(1) = 5

f(-4) = -2

so let's find b

so like if you do (5 - (-2))/(1 - (-4)) you get (5 + 2)/(1 + 4) = 7/5

y = 7/5x + b

so now we can plug in a value like f(1) = 5

5 = (7/5)1 + b

b = 18/5

The Correct statements are

B.⇒The circumcenter of triangle is the point where perpendicular bisector of sides meet.

Because three sides of triangle acts as a chord of the circle,and perpendicular bisector of chords intersects at the center of the circle.

C:⇒ Give any three non collinear points , there exist only one circle that passes through all the three points.

Join these points you will get two line segment .Draw perpendicular bisector of these segments.The point where these perpendicular bisectors meet is center of the circle.

E:⇒ The incenter of triangle is the point where internal bisector of angles meet.

Internal bisector of angle divide angle into two equal parts.The three line segements which is bisector of three angles meet at a point called Incenter of triangle.

The answer would be 10 units.

I hope this helped!

Answer: 10

Step-by-step explanation:

You need to apply the Pythagorean Theorem:

[tex]a^2=b^2+c^2[/tex]

Where "a" is the hypotenuse and "b" and "c" are the legs of the right triangle.

Since you need to calculate the value of the hypotenuse, you need to solve for "a":

[tex]a=\sqrt{b^2+c^2}[/tex]

You know the lenght of two sides of the right triangle (6 and 8) Then, you can  substitute these values into [tex]a=\sqrt{b^2+c^2}[/tex].

Therefore, the hypotenuse of this right triangle is:

 [tex]a=\sqrt{6^2+8^2}[/tex]

 [tex]a=10[/tex]

Answer:

m∠A = 42°

Step-by-step explanation:

* Lets revise some facts in the circle

- If the vertex of an angle on the circle and the two sides of the

 angle are chords in the circle, then this angle is called

 an inscribed angle

- Each inscribed angle subtended by the opposite arc, the arc name

 is the starting point and the ending point of the angle

# Ex: ∠CAB is subtended by arc CB

- There is a relation between the inscribed angle and its

  subtended arc, the measure of the inscribed angle equals half

  the measure of its subtended arc

* Now lets solve the problem

- ∠CAB is an inscribed angle subtended by arc CB

∴ m∠CAB = (1/2) measure of arc CB

∵ The measure of arc CB = 84°

∴ The measure of ∠A = 1/2 × 84° = 42°

* m∠A = 42°

9/30 cubic feet

Multiply the base area times the height to find the volume, which is the amount of packing material required.

First, multiply the numerators, or the top numbers. 9 * 1 = 9

Then, multiply the denominators, or the bottom numbers. 10 * 3 = 30

So, the amount of packing material required is 9/30 cubic feet.

Answer:

The glue stick with 3/8

Step-by-step explanation: if you make the denominators for both equations the same 1/5 would turn into 8/40 and 3/8 would turn into 15/40. This means that 3/8 would be 7% bigger  

The second glue stick has [tex]\( \frac{7}{40} \)[/tex] more glue than the first glue stick.

To compare the amount of glue left in each glue stick, we need to find a common denominator for [tex]\( \frac{1}{5} \)[/tex] and [tex]\( \frac{3}{8} \)[/tex].

The least common denominator (LCD) for 5 and 8 is 40.

Now, let's rewrite [tex]\( \frac{1}{5} \)[/tex] and [tex]\( \frac{3}{8} \)[/tex] with the common denominator of 40:

[tex]\[ \frac{1}{5} = \frac{1 \times 8}{5 \times 8} = \frac{8}{40} \]\[ \frac{3}{8} = \frac{3 \times 5}{8 \times 5} = \frac{15}{40} \][/tex]

Now, we can compare the amounts:

- Glue stick 1: [tex]\( \frac{8}{40} \)[/tex] left.

- Glue stick 2: [tex]\( \frac{15}{40} \)[/tex] left.

Since [tex]\( \frac{15}{40} \)[/tex]is greater than [tex]\( \frac{8}{40} \)[/tex], the second glue stick has more glue left.

Alternatively, we can also subtract the fractions to find the difference:

[tex]\[ \frac{15}{40} - \frac{8}{40} = \frac{15 - 8}{40} = \frac{7}{40} \][/tex]

B

[tex] \frac{1}{27} [/tex]

EXPLANATION

The given expression is

[tex] {3}^{ - 3} [/tex]

Use the negative index property;

[tex] {a}^{ - m} = \frac{1}{ {a}^{m} } [/tex]

We apply this property to get:

[tex]{3}^{ - 3} = \frac{1}{ {3}^{3} } [/tex]

This gives us:

[tex]{3}^{ - 3} = \frac{1}{3 \times 3 \times 3 } [/tex]

[tex]{3}^{ - 3} = \frac{1}{27} [/tex]

The correct option is B.

For this case we must evaluate the following expression:

[tex]3 ^ {3}[/tex]

We have by definition of properties of powers that:

[tex]a ^ {- 1} = \frac {1} {a ^ 1} = \frac {1} {a}[/tex]

Then, rewriting the expression:

[tex]3 ^ {- 3} = \frac {1} {3 ^ 3} = \frac {1} {27}[/tex]

ANswer:

[tex]3 ^ {- 3} = \frac {1} {27}[/tex]

Answer:

William is 18, Monica is 6... 6 x 3=18 Three times as old.. in 6 years William will be 24, Monica will be 12.. Twice as old... 12 x 2= 24

Step-by-step explanation:

Answer:

Current age of Monica=6 years

and current age of William=18 years

Step-by-step explanation:

Let Monica's current age be x years and William's current age be y years.

William is 3 times elder than Monica.

⇒  y=3x

In 6 years William will be twice as old as Monica.

⇒ y+6=2(x+6)

⇒ y+6=2x+12

⇒3x+6=2x+12

⇒ x=6

Hence, y=3×6=18

That means, current age of Monica=6 years

and current age of William=18 years

Answer:

$335.15

Step-by-step explanation:

(2012 price) - 11.1% · (2012 price) = (2013 price)

$377(1 - 0.111) = (2013 price)

$377 · 0.889 = $335.15 = (2013 price)

The average price of that type of smartphone in 2013 was $335.15.

Answer:

Price of smartphone in 2013 is $335.153.

Step-by-step explanation:

We are given the following information in the question.

Price of smartphone in 2012 = $377

Decline percentage of average price of phone from 2012 to 2013 = 11.1%

We have to calculate the the average price of mobile in 2013:

Formula:

Decrease in average price = [tex]\text{Price of smartphone in 2012}\times \text{Decline percent in average price}[/tex]

[tex]= \displaystyle\frac{11.1}{100}\times 377\\\\ =41.847\$[/tex]

Average price of smartphone in 2013 = [tex]\text{ Average price of smartphone in 2012 - Decrease in price of smartphone}\\= 377 - 41.847\\= 335.153[/tex]

Thus, the price of smartphone in 2013 is $335.153.

Answer:

8.94 inches or [tex] 8\frac { 1 5 } { 1 6 } [/tex] inches

Step-by-step explanation:

We know that the current height of the photo is [tex]3\frac{1}{4}[/tex] inches and the customer wants it to be enlarged by a factor of [tex]2\frac{3}{4}[/tex] its current height.

[tex]  3\frac { 1 } { 4 } = 3.25 [/tex]

[tex] 2 \frac { 3 } { 4 } = 2.75 [/tex]

To find the enlarged height, we will multiply the scale factor with the photo's current height.

Enlarged height = [tex]3.25 \times 2.75 = 8.94 inches or [tex] 8\frac { 1 5 } { 1 6 } [/tex] inches

Answer:

1. C.

2. B.

3. Add 6.1 to both sides

Step-by-step explanation:

1. Your equation here is "w + 2 < -1"

You must get w by itself, so to do that, subtract 2 from both sides.

w + 2 < -1

w < -3

Notice that the symbol is "w is less than -3" not "w is less than or equal to -3," so our plot must have a closed circle (or no open circle).

The larger the number behind the negative sign, the smaller it is.

ex: -3 is smaller than -1

So, the answer is C.

2. Here, you have the inequality -15 > q - 5

To find out which number set best fits the inequality, substitute the numbers in for the q value.

[I'll skip to answer B.]

B.'s number set is {-11, -12, -14}

So, plug in each value for q

For -11:

-15 > (-11) - 5

-15 > -16

This works.

(As I mentioned earlier, the larger the number in front of the negative, the smaller it is.)

For -12:

-15 > (-12) - 5

-15 > -17

This works as well

For -14:

-15 > (-14) - 5

-15 > -19

This works too

Thus, the answer is B.

3. And finally, you have the equation p - 6.1 = 10

To solve for p, make sure its alone on one side of the equation.

To do this, add 6.1 to both sides.

This is the first (and pretty much only) step to solve this equation

I hope this helps!!! :)

Step-by-step explanation:

90 is 50% of 180

50% = half

90 • 2 = 180

The expression is 180 is 50 percent of 90

From the question, we have the following parameters that can be used in our computation:

90 is 50 percent of what number

Represent the percentage with x

So, we have

90 is 50 percent of x

Mathematically, we have

50% * x = 90

So, we have

x = 90/50%

Express percentage as decimal

x = 90/0.50

Evaluate the expression

x = 180

Hence, the number in the percentage is 180
