Answer:

rock climb costs $7

Step-by-step explanation:

2 laser tags +3 rock climb = $31 ( 1 )

4 laser tags + 1 rock climb = $27 (2)

multipy (1) by -2 and add the equations

-4 laser tags -6 rock climb = $ -62

4 laser tags + 1 rock climb = $27

-6 rock climb +1 rock climb = -62+27

-5 rock climb = -35 divide both sides by -5

1 rock climb = $7

A circle has a radius of 5 in. A central angle that measures 150° cuts off an arc.

Slav-nsk [51]

Answer:

Part 1) The exact value of the arc length is $\frac{25}{6}\pi \ in$

Part 2) The approximate value of the arc length is $13.1\ in$

Step-by-step explanation:

step 1

Find the circumference of the circle

The circumference of a circle is equal to

$C=2\pi r$

we have

$r=5\ in$

substitute

$C=2\pi (5)$

$C=10\pi\ in$

step 2

Find the exact value of the arc length by a central angle of 150 degrees

Remember that the circumference of a circle subtends a central angle of 360 degrees

by proportion

$\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in$

step 3

Find the approximate value of the arc length

To find the approximate value, assume

$\pi =3.14$

substitute

$\frac{25}{6}(3.14)=13.1\ in$

Consider the image of EFGH for the translation (x, y) → (x – 3, y + 1). What is the ordered pair of F′?

omeli [17]

Answer:

$F'(-1,3)$

Step-by-step explanation:

The rule for the translation is given as

$(x,y)\rightarrow (x-3,y+1)$

The coordinates of F are (2,2).

We substitute these coordinates into the translation rule to find the coordinates of F'.

$F(2,2)\rightarrow F'(2-3,2+1)$

$F(2,2)\rightarrow F'(-1,3)$

What's -8 + (-1 1/8)

gogolik [260]

I think the answer is 9.375 if it needs to be in decimal form. If it needs to be in fraction form it would be improper, 9 3/8 would be the fraction. Hope it helps!

HELP!!!!!!!!!! WILL GIVE BRAINLY!!!!!!!

atroni [7]

Answer:

141 $in^{2}$

Step-by-step explanation:

Area of a trapezium = $\frac{h}{2}$ (a + b)

h = height

a and b = upper and and lower lengths

Area of a trapezium = $\frac{9}{2}$ (10 + 16)

= $\frac{9}{2}$ × 26

= 117 $in^{2}$

Area of a triangle = $\frac{1}{2}$ × base × height

= $\frac{1}{2}$ × 6 × 8

= $\frac{1}{2}$ × 48

= 24 $in^{2}$

Total area = Sum of the areas of both the shapes

= 117 + 24

= 141 $in^{2}$
