Answer:

7

Step-by-step explanation:

they asked how much the braclet cost, but they stated it in the question that the neckelss cost 5 dollers anr she has 12. so in you subtract 5 from 12 you get 7.

Answer:

The correct answer is 1/2×8×3.

Answer:

45

Step-by-step explanation:

7+11= 18

18/2=9

9*5=45

Answer:

B.

Step-by-step explanation:

Answer:

x ≈ 25.1

Step-by-step explanation:

Using the sine ratio in the right triangle

sin26° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{11}{x}[/tex] ( multiply both sides by x )

x × sin26° = 11 ( divide both sides by sin26° )

x = [tex]\frac{11}{sin26}[/tex] ≈ 25.1 ( to 1 dec. place )

"Correct" Answer:

53

Step-by-step explanation:

It's automadically 90 degrees because it's an acute angle, so you add 11 + 26 which gives you 37. Subtract 90 from 37 and it gives you 53, the variable.

26 + 11 = 37

90 - 37 = 53

Answer:

Step-by-step explanation:

First replace f(x) with y

[tex]y=-2x+2[/tex]

Then switch the variables

[tex]x=-2y+2[/tex]

Solve for the new y value

[tex]x-2=-2y\\[/tex]

[tex]-\frac{x-2}{2} =y[/tex]

Step-by-step explanation:

Answer:

B. False

Step-by-step explanation:

We are given the statement,

'The shapes of the horizontal cross-sections of the cone are all congruent'.

Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.

Further, the radius of the circle vary depending on the position form where the cone is cut i.e.

If cut from the top, the circle is approximately equal to a point.

If cut from the middle, the radius of the circle is less than the radius of the cone.

If cut from the bottom, the radius of the circle is equal to the radius of the cone.

Now, 'two figures are congruent if they overlap each other'.

Since, the circles have different radius, they will not overlap each other.

Thus, all the cross-sections of the cone would not be congruent.

Hence, the given statement is false.

Step-by-step explanation:

The solution is, the given statement is B. False.

A cross-section is a shape formed by cutting a solid (such as a cone, cylinder, or sphere) with a plane. If a cylinder-shaped object is cut by a plane parallel to its base, the resulting cross-section is a circle. As a result, the object intersected.

here, we have,

We are given the statement,

'The shapes of the horizontal cross-sections of the cone are all congruent'.

Now, if we cut the cone horizontally, the cross-sectional shape is a 'circle'.

Further, the radius of the circle vary depending on the position form where the cone is cut i.e.

If cut from the top, the circle is approximately equal to a point.

If cut from the middle, the radius of the circle is less than the radius of the cone.

If cut from the bottom, the radius of the circle is equal to the radius of the cone.

Now, 'two figures are congruent if they overlap each other'.

Since, the circles have different radius, they will not overlap each other.

Thus, all the cross-sections of the cone would not be congruent.

Hence, the given statement is false.

Answer:

  126.9°

Step-by-step explanation:

The sine of an angle is the same as the sine of its supplement. The other solution in the interval is ...

  180° -53.1° = 126.9°

Answer:

  B.  The area of P is 9 times the area of Q.

Step-by-step explanation:

The areas of similar figures are related by the square of the scale factor of their linear dimensions. The ratio of side lengths is ...

  side of P : side of Q = 6 : 2 = 3 : 1

So, the ratio of areas is ...

  area of P : area of Q = 3² : 1² = 9 : 1

The area of P is 9 times that of Q.

Answer:

It's a square

good luck, i hope this helps :)

Answer:

f(3) = 1

Step-by-step explanation:

To find f(3), plug in 3 as x and simplify the expression:

f(x) = 2x - 5

f(3) = 2(3) - 5

f(3) = 6 - 5

f(3) = 1

So, f(3) = 1

Answer: 25 girls

Step-by-step explanation:

Answer:

Your answer would be 189

Step-by-step explanation:

if you break the figure in to smaller parts you get for the two triangles 12*9/2. There are two of them, so that gets you 12*9/2+12*9/2, and all that equals 108. Finally, there is one more square in the middle, which equals 81, so 108+81=189, which is your answer.

Answer:

5 triangles are in a heptagon.

Answer: 1875km 840m

Step-by-step explanation:

From the question, we are informed that Gupty travelled 75km 800m by car and travelled 1800km 40m by aeroplane.

The distance that she travel altogether will then be:

= 75km 800m + 1800km 40m

= 1875km 840m

Answer: $94.49

Step-by-step explanation:

125.99 x 25/100

125.99 x 0.25

you save = $31.50

final price = original price - discount

final price = 125.99 - 31.4975

final price = $94.49

Answer:

5

Step-by-step explanation:

16 + 11x = 71

16 + -16 + 11x = 71 + -16

16 + -16 = 0

0 + 11x = 71 + -16

11x = 71 + -16

11x = 55

x = 5
