Answer:

189

Step-by-step explanation:

ratio is 8:9

multiply ratio by 21 to get 168:189

The number of people who threw the cabbage should be considered as the 189 when the ratio is given.

Since

The ratio of the number of people who threw tomatoes onto the stage to the number of people who threw cabbage was 8 to 9.

And,  168 people threw tomatoes onto the stage

So

[tex]= 168 \times 9 \div 8[/tex]

= 189

hence, The number of people who threw the cabbage should be considered as the 189 when the ratio is given.

Answer:

ΔT = -23.8°

Step-by-step explanation:

Given :-

To Find :-

Solving :-

The value of θ from the given equation is 48.59degrees

Given the trigonometry function

Sin(θ)=3/4

We are to find the value of theta that will make the expression true

Take the arcsin of both sides

arcsin Sin(θ)= arcsin(3/4)

θ = arcsin(3/4)

θ = 48.59

Hence the value of θ from the given equation is θ = 48.59 defense

Answer: y=2.17(2.96)

Step-by-step explanation: i took the test

Answer:   y = (x-2)/3

This is equivalent to y = (1/3)x - 2/3

=================================================

To get this answer, we need to swap x and y in the original equation. Then solve for y to get the inverse.

y = 3x+2

x = 3y + 2 ... x and y swapped

x-2 = 3y

3y = x-2

y = (x-2)/3

y = x/3 - 2/3

y = (1/3)x - 2/3

This final equation has slope 1/3 and y intercept -2/3

Using the slope concept, it is found that the boat traveled at a speed of 138 feet per minute.

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

At point A, we have that the vertical change is of 245 ft with an angle of 12º, hence the position in feet is given by:

[tex]\tan{12^\circ} = \frac{245}{x_A}[/tex]

[tex]x_A = \frac{245}{\tan{12^\circ}}[/tex]

[tex]x_A = 1152.6[/tex]

At point B, we have an angle of 28º, hence:

[tex]\tan{28^\circ} = \frac{245}{x_B}[/tex]

[tex]x_B = \frac{245}{\tan{28^\circ}}[/tex]

[tex]x_B = 460.7[/tex]

The distance in feet the boat traveled in 5 minutes was of:

[tex]d = x_A - x_B = 1152.6 - 460.8 = 691.8[/tex]

Velocity is distance divided by time, hence:

v = 691.8/5 = 138.

The boat traveled at a speed of 138 feet per minute.

The number is missing in the last step in the quadratic equation is 200. Then the correct option is D.

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

The quadratic equation is 8x² + 80x = −5

On adding and subtracting 200 on both sides, we have

8x² + 80x + 200 = −5 + 200

8 (x² + 10x + 25) = −5 + 200

Thus, the number is missing in the last step in the quadratic equation is 200. Then the correct option is D.

Answer:

Step-by-step explanation:

Zero has one square root which is 0. Negative numbers don't have real square roots since a square is either positive or 0. The square roots of numbers that are not a perfect square are members of the irrational numbers. This means that they can't be written as the quotient of two integers.

Answer:

False

Step-by-step explanation:

Every linear equation in two variables can be written as y=mx+c. 

Here, for each value of x there is a unique value of y. 

Also, x & y are in direct variation.

Hence, xy  will always remain constant.

Consequently, the graph will maintain a definite slope making it a straight line. 

∴ The given statement is false. 

Answer:

False

Step-by-step explanation:

=> y = 2x + 5

=> y - 2x = 5

=> - 2x + y = 5

=> (-2x + y) = 5

=> (-2/5)x + y/5 = 1

=> x/(-5/2) + y/5 = 1, it is in form of x/a + y/b = 1, a is intercept of x.

So, here, x intercept is -5/2.

Method 2;

=> y = 2x + 5

=> y = 2(x + 5/2)

=> y = 2{x - (-5/2)}, says, x intercept is - 5/2 & not - 2/5

Answer:

The correct option is;

A). Randomized block design

Step-by-step explanation:

In a randomized block design the experimental units or subjects of the experiment are separated into subgroups known as blocks with the property that the the variability (difference) of the parameters within the blocks are lesser than the variability between block, such that the treatment of the research or experiment are assigned differently to each block

The groups can therefore comprise of the following;

Group 1

15 men and 15 women to perform water aerobics for 30 minutes twice a week

Group 2

15 men and 15 women to perform water aerobics for 60 minutes once a week

Therefore, the effect of the experiment will be much less attributed to gender than to the durations of the water aerobic exercise.

24.84/7.2 = 3.45

The unit rate is $3.45 per gallon

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here: Linda pays $24.84 for 7.2 gallons of gas.

Thus unit rate ( dollars per gallon) = $24.84/7.2

                                                          =$3.45 per gallon
