How many teams haven't won a super bowl
A. 2
B. 12
C. None
D. 3

Answer:

8/17

Step-by-step explanation:

total students = 34

no of girls = 16

no of boys = 18

probability to choose a girl to answer the question = no of girls/total students

=16/34

=8/17

Step-by-step explanation:

It's the coordinates that the two lines cross at.

Answer:

x = 101/20, y = 1/4

Step-by-step explanation:

Solve the following system:

{-y + 5 x = 25 | (equation 1)

3 y + 5 x - 1 = 25 | (equation 2)

Express the system in standard form:

{5 x - y = 25 | (equation 1)

5 x + 3 y = 26 | (equation 2)

Subtract equation 1 from equation 2:

{5 x - y = 25 | (equation 1)

0 x+4 y = 1 | (equation 2)

Divide equation 2 by 4:

{5 x - y = 25 | (equation 1)

0 x+y = 1/4 | (equation 2)

Add equation 2 to equation 1:

{5 x+0 y = 101/4 | (equation 1)

0 x+y = 1/4 | (equation 2)

Divide equation 1 by 5:

{x+0 y = 101/20 | (equation 1)

0 x+y = 1/4 | (equation 2)

Collect results:

Answer: {x = 101/20, y = 1/4

Answer:

A

Step-by-step explanation:

Check the solution by substituting x = [tex]\frac{\pi }{2}[/tex] into the left side of the equation

2sin²x - sinx - 1

= 2sin²([tex]\frac{\pi }{2}[/tex] ) - sin ([tex]\frac{\pi }{2}[/tex] ) - 1

= 2(1)² - 1 - 1

= 2 - 1 - 1

= 0

= right side

[tex]\frac{\pi }{2}[/tex] is therefore a solution to the equation

Answer:

Angles 5 and 6 are next to each other and sum up to 180°.

Answer:

6cm

Step-by-step explanation:

Given data

Width= 4.6cm

Length= 9cm

Volume= 82.8cm^3

The expression for the volume is given as

V= lwh/3

82.8= 9*4.6*h/3

cross multiply

82.8*3= 9*4.6*h

248.4= 41.4h

h= 248.4/41.4

h= 6cm

Part (a)

The angles would stay the same. This is because similar figures keep the same shape, but the size will shrink or grow.

A real world application is to simply move your head closer to the page and the figure will appear to get larger. The angles themselves stay the same but the side lengths will get larger.

====================================================

Part (b)

While the angles stay the same under a dilation operation, the side lengths do not. As the instructions state: "The side lengths are 3 times longer" (paraphrased).

So we multiply each side length in the diagram by 3

Refer to the diagram below. I've used the resize feature to enlarge the image to make figure DEFG

Answer:

Step-by-step explanation:

angle 4 is congruent to angle 4 because they are alternate interior angles.

angle 5 is congruent to angle 3 because they are alternate interior angles.

angle 1+angle 2+angle 3 is equal to (=) angle 1+angle 2+angle 3

angle 1+angle 2+angle 3=180 degree(being sum of interior angles of a trianngle)

Answer:

y = -3x+ 4

one equation two unknows can not solve uniquely

4y = -12x + 16

y = -3x+ 4

is the solution set

Step-by-step explanation:

Answer:

[tex]x = \frac{ 16 - 4y}{12}[/tex]

Step-by-step explanation:

12x + 4y = 16

12x + 4y - 4y = 16 - 4y

12x = 16 - 4y

[tex]\frac{12x}{12} = \frac{ 16 - 4y}{12}[/tex]

[tex]x = \frac{ 16 - 4y}{12}[/tex]

Answer:

Then the solution is (-1/4, 3)

Step-by-step explanation:

Start by eliminating the fractional coefficient 1/4:  multiply all 3 terms in the second equation by 4.  This results in equation (b), below:

4x - 3y = -10   (a)

4x = y -4         (b)  

Substitute y - 4 for 4x in equation (a):

y - 4 - 3y = -10

Combining like terms, we get -2y = -10 + 4, or -2y = -6, or y = 3.

Since x = (1/4)y - 1, if y = 3, then x = (1/4)(3) - 1, or x = 3/4 - 1, or x = -1/4

Then the solution is (-1/4, 3)

Answer:x

permiter=6

area=24

Step-by-step explanation:

Answer:

x = 8, area = 364 km^2, perimeter = 80 km

Step-by-step explanation:

to start, we have to recognize that opposite sides of a rectangle are congruent.

therefore ➪

2x + 10 = 4x - 6

2x + 16 = 4x

16 = 2x

x = 8

now just plug that in and you'll find ➪

length = 26km

width = 14km

area = l * w

area = 26 * 14

area = 364 km^2

perimeter = 2(l + w)

perimeter = 2(14+26)

perimeter = 80 km

Answer: Coupon B gives the lower price

The price of coupon B is  3.75 dollars   less than the price of coupon A.

======================================================

Explanation:

15% off means she saves 15% of the original price.

15% of 95 = 0.15*95 = 14.25

Rachel saves $14.25 if she goes with coupon A.

We can see that coupon B gives the lower price because we have more in savings (since 18 is larger than 14.25).

If she goes with option A, then she spends 95-14.25 = 80.75 dollars. If she goes with option B, then she spends 95-18 = 77 dollars. Going with option B means she saves 80.75-77 = 3.75 dollars

Or you could note that 18-14.25 = 3.75 is another way to find out how much is saved when comparing the two coupons.

Answer:

x = 10

Step-by-step explanation:

The secant- secant angle 3x is half the difference of the intercepted arcs, that is

3x = [tex]\frac{1}{2}[/tex] (4x + 50 - 30 )

3x = [tex]\frac{1}{2}[/tex] (4x + 20) = 2x + 10 ( subtract 2x from both sides )

x = 10

Answer:

H: 41

Step-by-step explanation:

upfront charge = 36

each cone costs .52

sell price 1.40

(sell price - cone cost) * number of cones - upfront cost =0 to find where break even is

-36+(1.40-.52)*x=0

-36+.88x=0

.88x=36

x=40.90

need to round up to break even to 41

Answer:

Option C 41 is correct answer.

Given:

Cost of rent of the equipment = 36 $

Cost on ingredients of each cone = 0.52 $

Selling price of each cone = 1.40

To find:

Number of cones(let = x) joel must sell in order to make a profit?

1.40x > 36+ 0.52x

subtracting 0.52 x from both the side,

1.40x - 0.52x > 36

0.88x > 36

dividing both side by 0.88,

x > 36/0.88

x> 40.909090....~ 41

Option C 41 is correct answer.

Answer:

x= 15

Step-by-step explanation:

Answer:

The answer is 3

Step-by-step explanation:

It's just wisdom I mean think about it it

1.5 then 3

⭐ Initially, we have to find the reason why it was -1.5:

[tex]\large {\text {$ \sf f (n+1) = -2 f(n) $}}[/tex]

➡️ Having n, then we'll find the value of n, then we'll replace it with the found result.

[tex]\large {\text {$ \sf f (x+1) = -2.x = -1,5 $}}[/tex]

⌛ So, we will have to find what x is worth in this case:

[tex]\large {\text {$ \sf f ( 0,75 +1 ) = -2 \cdot 0,75 $}}[/tex]

[tex]\large {\text {$ \sf f ( 0,75) = -1,5 $}}[/tex]

→ Knowing this...

[tex]\large {\text {$ \sf f ( 1,5 + 1 ) = -2 \cdot 1,5 $}}[/tex]

[tex]\large {\boxed {\boxed {\sf f ( 2,5 ) = -3 }}}[/tex]     [tex]\checkmark[/tex]
