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]

So, Volume of square pyramid=120,000 m³

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: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:

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:

It is only 3,9.

Step-by-step explanation:

You need to substitute each pair into the equation to find if both side have the same answer, 3,9 is the correct answer because both sides are equal:

2(9) = 7(3)-3

18= 18

The answer is (3,9).

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

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

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:

  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.

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.

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
