Answer:

5.5

Step-by-step explanation:

Sales tax = tax rate × Cost of meal

Sales tax = $1.32

Tax rate = x%

Cost of meal = $24

Sales tax = tax rate × Cost of meal

1.32 = x% × 24

1.32 = x/100 × 24

1.32 = 24x/100

1.32 * 100 = 24x

132 = 24x

x = 132/24

x = 5.5%

= 5.5

Answer:

b=7/33 c= 14/33

Step-by-step explanation:

Repeat all 21 they are repeating decimals

for b its 100x-x=21.21 repeating the 21 -0.21 repeating the 21 = 100x-1x=(21+0.21)-0.21= (100-1)x=21+0.21-0.21 [ stop repeating the 21's up to here] and 99x=21+0 = 99x=21 = 99x/99=21/99 both 99's cancel leaving 3x7 divided by 3x33 = x= cancel both 3's leaving 7 over 33 This should help you learn to solve c good luck

Answer:

61

Step-by-step explanation:

1/5 = .2

so you do 12.2 / .2 which gives you 61

Answer:

Your answer is 61

Step-by-step explanation:

Step 1.  Convert 12.2 into a fraction. (I chose to put 12.2 over 10 so in the end it's 122/10.)

Step 2. Layout your problem

Remeber when dividing fractions it Keep, Change, Flip.

122/10 x 5/1

Step 3. Solve

122/10 x 5/1 = 61

Answer:

40.5

Step-by-step explanation:

a cube has 6 faces so 6.75 x 6 = 40.5

Answer and explanation:

Given the above, we find y in terms x

change in y change in x = 0.5

The formula for a straight line is y= mx+b where m is slope of the line and b is the y intercept

We substitute given values above in the straight line equation:

y=mx+b

1.5= 0.5×3+b

1.5=1.5+b

b= 0

y in terms of x for the line is therefore given by the formula :

y=0.5x+0

Answer:

C (The lower left one)

Step-by-step explanation:

I saw that the vertex was equal to (-1,1) and that is the only answer that makes sense

The graph of the function y = x shifted 1 unit up and moved 1 unit to the left

so the new function is now y = (x + 1) + 1.

The set of ordered pairings (x, y) where f(x) = y makes up the graph of a function.

These pairs are Cartesian coordinates of points in two-dimensional space and so constitute a subset of this plane in the general case when f(x) are real values.

By observing the figure we conclude that it shifted 1 unit up and moved 1 unit to the left.

If the original graph was y = x now it is y = (x + 1) + 1.

Answer:

[tex]c=\frac{3}{7}f[/tex]

Step-by-step explanation:

Clare uses [tex]9\frac{1}{3}[/tex] cups of flour to make 4 cakes.

Noah follows the same recipe so the ratio of the ingredients used will be proportional.

If Noah uses f cups of flour for c cakes,

[tex]\frac{c}{f} =\frac{4}{9\frac{1}{3}}[/tex]

[tex]\frac{c}{f} =\frac{4}{\frac{28}{3}}[/tex]

[tex]\frac{c}{f} =\frac{4\times 3}{28}[/tex]

[tex]c=\frac{3}{7}f[/tex]

Therefore, relation between cake and flour used is,

Probability of an event is the measure of its chance of occurrence. The experimental probability of Janice rolling the number four is 0.2

Experimental probability calculates the probability of some event from the results of experiments.

For an event E, we get the experimental probability of that event

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]

where, [tex]P_e(E)[/tex] is denoting experimental probability of occurrence of E.

For this case, we're specified that:

The event in consideration is "Rolling the number 4"

The times she rolled the number 4 is: 12

She got four 12 times in 60 rolls of the considered cube.

Thus, we have:

Thus, we get:

[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}} = \dfrac{12}{60} = \dfrac{1}{5} = 0.2[/tex]

Thus, the experimental probability of Janice rolling the number four is 0.2

-17 - (-7) = -24

a = -24

Answer:

b) a = -10

Step-by-step explanation:

a + (-7) = -17

simplify

a - 7 = -17

add 7 to both sides of the equation

a - 7 + 7 = -17 + 7

a = -17 + 7

a = -10

Answer:

(-3,-1)

Step-by-step explanation:

6x-12y=-6

6x=12y-6

x=2y-1

9(2y-1)-6y= -21

18y-9-6y=-21

12y= -12

y=-1

6x-12(-1)=-6

6x+12= -6

6x=-18

x=-3

Answer:

x = -3 ; y = -1

Step-by-step explanation:

Let 9x - 6y = -21 be eqn.1 & let 6x - 12y = -6 be eqn.2 .

Lets find the value of x from eqn.1

[tex]9x - 6y= -21[/tex]

[tex]=> 3(3x - 2y) = -21[/tex]

[tex]=> 3x - 2y = \frac{-21}{3} = -7[/tex]

[tex]=> x = \frac{2y - 7}{3}[/tex]

Now , lets put the value of x (which we got from eqn.1) in eqn.2 :-

[tex]6x - 12y = -6[/tex]

[tex]=> 6(x - 2y) = -6[/tex]

[tex]=> x - 2y = \frac{-6}{6} = -1[/tex]

(Putting x here)

[tex]=> \frac{2y - 7}{3} - 2y = -1[/tex]

[tex]=> \frac{2y - 7 - 6x}{3} = - 1[/tex]

[tex]=> -4 y - 7 = -1 \times 3 = -3[/tex]

[tex]=> -4y = 7 - 3 = 4[/tex]

[tex]=> y = \frac{-4}{4} = -1[/tex]

Now , lets find the value of x.

[tex]x = \frac{2y - 7}{3}[/tex]

Putting y = -0.5 gives ,

[tex]x = \frac{[2 \times (-1)] - 7}{3}[/tex]

[tex]=> x = \frac{-2 - 7}{3} = \frac{-9}{3} = -3[/tex]

Answer:

Supplementary angles and adjacent angle

Step-by-step explanation:

Both angles x° and angle 157° are supplementary ; this is because the sum of both angles should add up to 180°.Looking closely, each both angles will combine to form angle on a Straight line which from angle theorem adds up to 180°.

Also both angles x° and 157° are adjacent angles most simply because they share a common vertex(this can be interpreted as the point of intersection of the two lines which makes up the diagram.)

Step one:

Given data

A kangaroo hops 2 kilometers in 3 minutes

The rate/speed is

rate/speed= 2/3 km per minute

Required

the time taken to cover 3 km

Step two:

We know that

rate= distance/time

2/3= 3/t

cross multiply we have

2t=3*3

2t=9

divide both sides by 2

t= 9/2

t= 4.5 minutes
