Answer:

  1.8 miles

Step-by-step explanation:

In the first half hour, Sandra hikes 9/10 = 0.9 miles. She hikes that distance again in the second half-hour. After an hour, Sandra has hiked ...

  2 × 0.9 miles = 1.8 miles

__

If you like, you can consider it a "unit rate" problem. To find miles per hour, divide miles by hours:

  (9/10 mi)/(1/2 h) = (9/10)(2/1) mi/h = 9/5 mi/h = 1.8 mi/h

Sandra hikes 9/5 or 1.8 miles in an hour.

Answer:

C

Step-by-step explanation:

Use Δ ABC to find AB then Δ ABD to find DB

Δ ABC  is isosceles since ∠ CAB = ∠ CBA = 45° , then CB = CA = 2

Using Pythagoras' identity in Δ ABC , then

AB² = 2² + 2² = 4 + 4 = 8 ( take square root of both sides )

AB = [tex]\sqrt{8}[/tex] = 2[tex]\sqrt{2}[/tex]

----------------------------------------------------------------

Using the sine ratio in Δ ABD with the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{AB}{DB}[/tex] = [tex]\frac{2\sqrt{2} }{DB}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

[tex]\sqrt{3}[/tex] × DB = 4[tex]\sqrt{2}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

DB = [tex]\frac{4\sqrt{2} }{\sqrt{3} }[/tex] ( multiply numerator/ denominator by [tex]\sqrt{3}[/tex] to rationalise denominator )

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

     = [tex]\frac{4\sqrt{6} }{3}[/tex] → C

Answer:

Rise over Run, the slope in this graph would be 3/4

Step-by-step explanation:

You count the number of spaces it takes to move up, then you move right, towards the line. You write the rise number on top and the number moving right (run) on the bottom, (rise over run).

1 1/2 x 12

Key: Keep, change, flip.

So 1 1/2 you have to make it into a improper fraction.

1 1/2 to 3/2 x 12/1 = 3/2 x 1/12 = 1/2 x 1/4 = 1/8

Hope this answer helps :)

Answer:

41

Step-by-step explanation:

The absolute value function always gives a positive result, that is

| - a | = | a | = a

Given

6r - | - 8 + v | ← substitute v = 1 and r = 7 into the expression

= 6(7) - | - 8 + 1 |

= 42 - | - 1 |

= 42 - 1

= 41

Answer:

b) simplify the constant

c)isolate the variable by dividing the coefficient

Step-by-step explanation:

Answer:X = 48

Step-by-step explanation:

Solve for  

x

by simplifying both sides of the equation, then isolating the variable.

The value of x in the equation given 3x/4 - 9 = 27, is 48.

Given is an equation, 3x/4 - 9 = 27, we need to find the value of x,

To find the value of x, we can solve the given equation step by step. Let's go through the process:

Start with the equation:

3x/4 - 9 = 27

To eliminate the fraction, we can multiply both sides of the equation by 4:

4 × (3x/4 - 9) = 4 × 27

Simplifying, we have:

3x - 36 = 108

Add 36 to both sides of the equation to isolate the variable:

3x - 36 + 36 = 108 + 36

Simplifying further:

3x = 144

Divide both sides of the equation by 3 to solve for x:

(3x) / 3 = 144 / 3

This gives us:

x = 48

Therefore, x equals 48 in the given equation: 3x/4 - 9 = 27.

Answer:

12 coins

Step-by-step explanation:

Points scored by collecting 7 coins = 581

Number of coins required to collect 996 points

Let Number of coins = c

7 coins = 581 points

c coins = 996 points

Cross multiply :

581 * c = 996 * 7

581c = 6972

Divide both sides by 581

581c / 581 = 6972 / 581

c = 12

Hence, number of coins required to collect 996 points is 12

Answer:

Step-by-step explanation:

Let p represent the number of pounds of plastic bricks in the mix. Then the number of pounds of wooden blocks is (10-p), and the total cost is ...

  10p +5(10-p) = 80

  5p = 30 . . . . . . . . . subtract 50

  p = 6 . . . . divide by 5; there are 6 pounds of plastic bricks in the mix

4 pounds of wooden blocks and 6 pounds of plastic bricks should be used to make a 10-lb mix worth $80.

Answer:

The coordinates of point B' are (3, 9)

Step-by-step explanation:

If the point (x, y) translated by a vector <a, b>, then its image is (x + a, y + b)

Let us use this rule to solve the question

In Δ ABC

∵ The coordinates of vertex A are (1, 3)

∵ The coordinates of vertex B are (2, 5)

∵ The coordinates of vertex C are (5, 3)

∵ Δ ABC is translated by the vector <1, 4>

→ By using the rule above add the x-coordinate of point B by 1

   and the y-coordinate of point B by 4

∴ B' = (2 + 1, 5 + 4)

∴ B' = (3, 9)

∴ The coordinates of point B' are (3, 9)

Answer:

30 and 10

Step-by-step explanation:

Given ratio of age = 3 : 1 = 3x : x ( x is a multiplier )

Six years ago their age ratio was

3x - 6 : x - 6 = 6 : 1 ← express in fractional form

[tex]\frac{3x-6}{x-6}[/tex] = [tex]\frac{6}{1}[/tex] ( cross- multiply )

6(x - 6) =3 x - 6

6x - 36 = 3x - 6 ( subtract 3x from both sides )

3x - 36 = - 6 ( add 36 to both sides )

3x = 30 ( divide both sides by 3 )

x = 10

Thus their present ages are

mother = 3x = 3 × 10 = 30

daughter = x = 10

Answer:

Volume of square pyramid=120,000 m³

Step-by-step explanation:

We are given: Base of square pyramid = 60 m

Height of square pyramid = 100 m

We need to find Volume of square pyramid.

The formula used is: [tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h[/tex]

Where a is base and h is height of square pyramid

Putting values in formula and finding volume of square pyramid

[tex]Volume \ of \ square \ pyramid=\frac{1}{3}a^2h\\Volume \ of \ square \ pyramid=\frac{1}{3}(60)^2(100)\\Volume \ of \ square \ pyramid=\frac{1}{3}(3600)(100)\\Volume \ of \ square \ pyramid=120,000\ m ^3[/tex]

Step-by-step explanation:

Jimmy's group : has 841 students

Lauren's group: has 351 students

9 vans  16 buses

8 vans 5 buses              

Vans: V

Buses: B

9v + 16b = 841

9v + 16b = 841

        -16b     -16b

9v/ 9 = 841 /9 - 16b/9

8( 841/9 - 16b/9) +5b = 351

v - (841/ 9 - 16b / 9 )

8 (841 / 9 - 16b/9) +5b =  351

6728/9 - 128b / 9 +5b = 351

-128b/9 + 45b/9 = -83/9b

6728/9 -83/9

- 6728/9   +83/9 = 3159/9 - 6728/9

(9)83b / 9 = -3569 (9)/9

-83b = -3564

-83        -83

B = 43 students

8v + 5b = 351  

8v + 5 (43) = 351

8v + 215 = 315

      -215      -215

8v = 136

8        8

V = 17 students

43 students can fit on a bus and 17 students can fit in a van.
