Step-by-step explanation:

If she's represented by diamonds, then that's 2/25 which is 8%, C

Answer:

Step-by-step explanation:

8%

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:

Step-by-step explanation:

[tex]\frac{9}{6}[/tex] ÷ [tex]\frac{1}{2}[/tex] = 3

Answer:Number of Spearmint gum = 27 pieces

Step-by-step explanation:

step 1

Let the total number of peppermint gum and spearmint gum in the container = X

Ratio of peppermint gum to  spearmint gum=  2 : 3.

Total ratio = 2+ 3=5

Step 2

we were given that  peppermint gum= 18 pieces , so total number of gums  will be calculated as

Ratio of peppermint/ Total ratio x Total number of gums = Number of peppermint

2/5 x X= 18

X=(18X 5) / 2 = 45

X=  Total number of gums = 45

Number of spearmint gum  will now be

Ratio of spearmint/ Total ratio x Total number of gums = Number of spearmint

3/5 x 45= 27

Therefore Number of Spearmint gum = 27 pieces

Answer: 96

seth got 18 more than frank

in terms of ratio he got 3 more than frank

this means that 3 is equal to 18

so we find the whole ratio to fing the total

Answer:

im pretty sure it would be -8-(-6)=-2 for the first one

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:

  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:

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)

The linear function will be represented as h(x) = -3x - 10.5. The correct option is A.

The terms "linear function" in mathematics refer to two different but related ideas: A linear function is a function with a graph that is a straight line in calculus and related fields.

The given data in the table is:-

X   -7.5     -3.5      -1         2

Y    12         0       -7.5    -16.5

The linear function can be written as:-

y = mx + c

m = ( 0 - 12 ) / ( -3.5 + 7.5 )

m = -12 / 4

m = -3

The y-intercept will be:-

y = mx + c

0 = ( -3 x -3.5 ) +c

c = -10.5

The linear function is:-

h(x) = -3x - 10.5

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:?

Step-by-step explanation:

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

Quantity of water used to make a medicine :-

[tex]= \texttt{1 \: litre }[/tex]

[tex] =\texttt{ 1×1000 \: ml}[/tex]

[tex] =\texttt{\color{hotpink} 1000 \: ml}[/tex]

This quantity of water required to make a medicine = 1000 ml

Quantity of sucrose used to make a medicine = 150 ml

Quanity of saline solution used to make a medicine = 600 ml

The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-

[tex] = \texttt{1000 : 150 : 600}[/tex]

Cutting each common zero in this ratio, we get :-

[tex] = \texttt{100 : 15 : 60}[/tex]

Dividing each number in the ratio by 5, we get the ratio :-

[tex] =\texttt{ \color{hotpink}20 : 3 : 12}[/tex]

Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .

Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12

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

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.

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

V = 17 students

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