Answer:

2 hours per day

Step-by-step explanation:

19.5 - 5.5 = 14

14 / 7 = 2 hours per day

Mary needs to rehearse 2 hours per day for the next 7 days to meet her total rehearsal goal.

To calculate the total rehearsal time for Mary:

She has rehearsed for 5.5 hours.

She wants to rehearse a total of 19.5 hours.

Therefore, 19.5 - 5.5 = 14 hours

She needs to rehearse an additional 14 hours in the upcoming week.

To find out how many hours Mary must rehearse per day in the next 7 days:

14 / 7 = 2 hours/day

Answer:1.33

Step-by-step explanation:

Byron spent $1.38 more than Cassandra on other groceries, as we subtracted Cassandra's spending ($11.50) from Byron's ($12.88) to determine the difference.

The question asks us to determine how much more money Byron spent compared to Cassandra on their grocery shopping. To find this out, we need to compare the total amount of money each person spent. We have the cost of other groceries for each person, but the cost of yogurt is not given. To solve this problem, we just need to compare the cost of other groceries since that is the only information provided.

Byron spent $12.88 on other groceries.

Cassandra spent $11.50 on other groceries.

To find out how much more Byron spent, we subtract Cassandra's total from Byron's total:

$12.88 - $11.50 = $1.38

Therefore, Byron spent $1.38 more than Cassandra on other groceries.

Answer:

22, 17, and 44.

Step-by-step explanation:

So what you do is you will have three equations that we will put together.

1. x. The first number is x because they don't give us anything about it.

2. x-5. It says that the second number is 5 less than the first number.

3. 2x. It says that the third number is 2 times the first number.

x+x-5+2x=83.

4x-5=83.

4x=88.

x=22.

That is the first number. To find the second and third, you will plug 22 into the x.

2. 22-5=17.

3. 2(22)=44.

22, 17, 44 are your answers.

Final answer:

By setting up equations based on the information provided, we solved for x as the first number and then used it to determine the other two numbers. The three numbers are 22, 17, and 44.

Explanation:

The sum of three numbers is 83. This is the first equation we'll use to solve the problem. Let's denote the first number as x. According to the question, the second number is 5 less than the first, which gives us the second equation y = x - 5. For the third number, it is given as 2 times the first, hence the third equation is z = 2x.

Now, we'll combine all three equations to express the sum:

x + (x - 5) + 2x = 83

Simplifying, we combine like terms:

4x - 5 = 83

Adding 5 to both sides gives us:

4x = 88

Dividing by 4, we find the first number:

x = 22

Now we'll use x to find the other two numbers:

y = 22 - 5 = 17

z = 2 × 22 = 44

Therefore, the three numbers are 22, 17, and 44.

Answer:

x = 12 and y = 0

Step-by-step explanation:

Use elimination by adding the equations together.

-2x + 15y =-24

2x + 9y =  24

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

24y = 0

y=0

Then substitute y = 0 into one equation to find x.

-2x + 15(0) = -24

-2x + 0 = -24

-2x = -24

x = 12

Answer: x = 12 y = 0

Answer:

Part 1) The radius of the circle is [tex]17\ units[/tex]

Part 2) The points (15,14) and (-15,-16) lies on this circle

Step-by-step explanation:

Part 1

we know that

The distance between the center of the circle at point (-7,-1) and the point (8,7) is equal to the radius of the circle

so

the formula to calculate the distance between two points is equal to

[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]

substitute the values

[tex]r=\sqrt{(7+1)^{2}+(8+7)^{2}}[/tex]

[tex]r=\sqrt{(8)^{2}+(15)^{2}}[/tex]

[tex]r=\sqrt{289}}[/tex]

[tex]r=17\ units[/tex]

Part 2

we know that

If the point (-15,y) lies on the circle, then the ordered pair must be satisfy the equation of the circle

The equation of the circle is equal to

[tex](x+7)^{2}+(y+1)^{2}=17^{2}[/tex] -----> equation of the circle in center radius form

substitute the value of x=-15 in the equation and solve for y

[tex](-15+7)^{2}+(y+1)^{2}=289[/tex]

[tex]64+(y+1)^{2}=289[/tex]

[tex](y+1)^{2}=289-64[/tex]

[tex](y+1)^{2}=225[/tex]

[tex]y+1=(+/-)15[/tex]

[tex]y=-1(+/-)15[/tex]

so

[tex]y=14[/tex]

[tex]y=-16[/tex]

therefore

The points (15,14) and (-15,-16) lies on this circle

see the attached figure to better understand the problem

Step-by-step explanation:

we know that

The inscribed angle measures half that of the arc comprising

so

[tex]m<A=\frac{1}{2}(arc\ KE+arc\ EW)[/tex]

substitute the values and solve for x

[tex](x+45)\°=\frac{1}{2}(x+20+3x)\°[/tex]

[tex](2x+90)\°=(4x+20)\°[/tex]

[tex]4x-2x=90\°-20\°[/tex]

[tex]2x=70\°[/tex]

[tex]x=70\°/2=35\°[/tex]

Find the measure of the arc KW

[tex]arc\ KW=(arc\ KE+arc\ EW)=(4x+20)\°[/tex]

substitute the value of x

[tex]arc\ KW=4(35\°)+20\°=160\°[/tex]

Step-by-step explanation:

Two creek crossings are separated by distance A = 7.2 inches on the map.

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

The information is ,

Let's say the equation looks like this: A

Right now, A is valued at

The two stream crossings' separation is indicated on the map as A.

And on the chart, 3 inches equals 0.75 miles, therefore the distance between the two stream crossings is 1.8 miles.

hence, 3 / 0.75 inches Equals 1 mile.

In the map, 1 mile equals 4 inches after simplifying the calculation.

The two creek crossing's distance on the map is therefore equal to 1.8 x 4.

The two stream crossings will be separated by 7.2 inches on map A.

Hence, the distance on the map is 7.2 inches.

ANSWER

f(x) is an odd function.

EXPLANATION

The given function is symmetric with respect to the origin.

Hence it is an odd function.

We can also see from the graph that,

[tex]f(1) = 2[/tex]

and

[tex]f( - 1) = - 2[/tex]

This implies that,

[tex]f( - 1) = - f(1)[/tex]

Since

[tex]f( - x) = - f(x)[/tex]

the function is odd.

The correct answer is A.

Answer:

36°

Step-by-step explanation:

∠A + ∠B + ∠C = 180°

∠A:∠B:∠C = 8:10:12 = 8x:10x:12x

8x + 10x + 12x = 180

                20x = 180

                    x =     9

∠A =   8x =  8 × 9 =  72°

∠B = 10x = 10 × 9 =  90°

∠C = 12x = 12 × 9 = 108°

∠C - ∠A = 108 -72 = 36 °

The difference between the largest and the smallest angle is 36°.

Part b) The dilation is an enlargement, because the corresponding sides of the image are larger than the corresponding sides of the original figure.(the scale factor is greater than 1)

Part c) The scale factor is [tex]3[/tex]

Step-by-step explanation:

Part a) Write the similarity statement

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional

so

[tex]\frac{AB}{A'B'}=\frac{BC}{B'C'} =\frac{AC}{A'C'}[/tex]

substitute the values

[tex]\frac{9}{27}=\frac{12}{36} =\frac{15}{45'}[/tex]

[tex]\frac{1}{3}=\frac{1}{3} =\frac{1}{3'}[/tex] ----> is true

therefore

the figures are similar

Part b) The dilation is an enlargement, because the corresponding sides of the image are larger than the corresponding sides of the original figure. (the scale factor is greater than 1)

Part c) we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z------> the scale factor

x-----> corresponding side of the image

y------> corresponding side of the original figure

so

[tex]z=\frac{x}{y}[/tex]

we have

[tex]x=A'B'=27\ units[/tex]

[tex]y=AB=9\ units[/tex]

substitute

[tex]z=\frac{27}{9}=3[/tex]

The scale factor is greater than 1

therefore

Is an enlargement

Answer:(A) ab/a’b’=bc/b’c’=ac/a’c’ (B) Figure a’b’c’ is an enlargement because it increase it’s sides larger than 1. (C) So we have to divide to get the scale factor for both of these figures 18/6=3 then you found the scale factor 3.

We are given that the area of a home bakes pizza is [tex] 6 2 5 \pi cm ^ 2[/tex].

Here, we are assuming that the pizza is circular and we know that the area of a circle is given by: [tex]\pi r^2[/tex]

So equating the given value to find the value of the diameter.

[tex]\pi r^2[/tex] [tex]=625\pi[/tex]

[tex]r^2=625[/tex]

[tex]r=\sqrt{625}[/tex]

[tex]r=25[/tex]

If the radius is 25 cm, then  diameter = 25 × 2 = 50 cm

Answer:

The diameter of the pizza= 50 cm

Step-by-step explanation:

Points to remember

Area of circle = πr²

Where r is the radius of circle

It is given that, area of pizza is 625π cm²

A pizza is like a circle.

Find the radius of pizza

Area = πr²= 625π cm²

r² = 625π/π = 625

r = √625 = ±25

radius r = 25cm

To find the diameter of pizza

Diameter = 2r  = 2 * 25 = 50 cm

Meters

Step-by-step explanation:

Because centimeters are to small to be a reasonable measurement for a car so you would have to use meters

The measure of Angle 1 is 35 degrees and the measure of Angle 2 is 55 degrees.

When two angles are complementary, their measures add up to 90 degrees. Let's define these two angles as follows: Angle 1 = x and Angle 2 = 2x - 15 (since it is 15 degrees less than twice the measure of Angle 1). You set up an equation based on the fact that the two angles add up to 90 degrees: x + 2x - 15 = 90. Solving this equation, you get 3x = 105, so x = 35. Thus, Angle 1 = 35° and Angle 2 = 2(35) - 15 = 55°.

Answer:

3 sin(41t) - 3 sin(t)

Step-by-step explanation:

The general formula to convert the product of the form cos(a)sin(b) into sum is:

cos(a) sin(b) = 0.5 [ sin(a+b) - sin (a-b) ]

The given product is:

6 cos(21t) sin(20t) = 6 [ cos(21t) sin(20t) ]

Comparing the given product with general product mentioned above, we get:

a = 21t and b = 20t

Using these values in the formula we get:

6 cos(21t) sin(20t) = 6 x 0.5 [ sin(21t+20t) - sin(21t-20t)]

= 3 [sin(41t) - sin(t)]

= 3 sin(41t) - 3 sin(t)

Therefore, second option gives the correct answer
