Julie sees a ride that spins 10 turns each minute. She says it will spin 40 turns in 4 minutes. Is Julie correct? Explain.

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

1 minute = 10 turns

4 minutes = 40 turns

• This is direct proportion. As one side increases by a value so must the other. In this case 1 min has become 4 mins. This has been multiplied by 4. So 10 must be multiplied by 4 too. 4 × 10 = 40 turns.

Answer 2

Triangle HIJ is dilated by a scale factor of 55 to form triangle H'I'J'. Side I'J' measures 7575. What is the measure of side IJ? (marking brainliest)

Answers

Answer:

If triangle HIJ is dilated about the center of the triangle to create triangle H'I'J', dilated line A'B' will be parallel to AB.Option (D) is correct.

Given:

The options are as follows,

(A). be perpendicular to AB.

(B). lie on the same line as AB.

(C). shift four units to the left.

(D). be parallel to AB.

Step-by-step explanation:

If we dilate triangle HIJ then the dilated triangle  is bigger than the triangle HIJ.

The triangle HIJ is similar to triangle  to each other.

So the line  is parallel to side AB.

M < 7 is the answer because if m was equal to seven the equation would be 19 > 19 which cannot be correct so m must be less than 7

Option d. m>7 is the correct answer.

Given,

     2m+5>19

or, 2m+5+(-5)>19+(-5)      [adding both side with a negative number doesn't

                                           change the inequality sign]

or, 2m>14

or, (2m/2)>(14/2)             [also dividing both sides by a non-negative number     doesn't change the inequality sign]

or, m>7.

Hence, m>7 is the correct answer to the given question.

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.


Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.


Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

A right triangle is drawn on graph paper. The length of the legs measure 1.5 centimeters and 2 centimeters. The length of the hypotenuse measures 2.5 centimeters. Write an equation using the triangle’s side lengths to show the Pythagorean Theorem holds true for the triangle.

Answers

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.

In this case, let's denote the lengths of the legs as a = 1.5 centimeters and b = 2 centimeters, and the length of the hypotenuse as c = 2.5 centimeters.

The equation using the triangle's side lengths to show the Pythagorean Theorem holds true for the triangle is:

a^2 + b^2 = c^2

Substituting the given values, we have:

(1.5)^2 + (2)^2 = (2.5)^2

2.25 + 4 = 6.25

6.25 = 6.25

Therefore, the equation holds true, confirming that the Pythagorean Theorem is satisfied for the given right triangle.

\(\huge{\mathfrak{\colorbox{black}{\textcolor{lime}{I\:hope\:this\:helps\:!\:\:}}}}\)

♥️ \(\large{\textcolor{red}{\underline{\mathcal{SUMIT\:\:ROY\:\:(:\:\:}}}}\)

The Pythagorean Theroem states a^2+b^2=c^2. It is true because 1.5^2+2^2=2.5^2. 2.25+4=6.25.

2/3m X 2 = 4/6m

4/6m + 5/6m = 11/6m=1 5/6m

Answer:

50, 40, 30, 250, 350

Step-by-step explanation:

1/2 = 0.5, 0.5 x 100 = 50 (0.5 -> 5 -> 50)

2/5 = 0.4 (10 / 5 [the denominator] = 2, 0.2 x 2 [the numerator] = 0.4), 0.4 x 100 = 40 (0.4 -> 4 -> 40)

3/10 = (10 / 10 [the denominator] = 1, 0.1 x 3 [the numerator] = 0.3), 0.3 x 100 = 30 (0.3 -> 3 -> 30)

5/2 = 2.5 (2 1/2), 2.5 x 100 = 250 (2.5 -> 25 -> 250)

7/2 = 3.5 (3 1/2), 3.5 x 100 = 350 (3.5 -> 35 -> 350)

Note: I'm not sure if I understand the question completely, but I changed the fraction into a decimal and multiplied it by 100. Not sure what it means by "Divide fraction".

Answer:

According to the question , firstly we have to divide the fraction and then convert them into percentage

So , let's do it :-

We need to find a common multiple, for the denominator. Let us choose 6, so we do not have to deal with large numbers.

Note that we do not change 4/6, since it already has a denominator of 6.

Answer:

y=180-x is correct and finally y+x=180-46 is also correct

Step-by-step explanation:

Since all triangles add up to 180 degrees(so y+x+46=180 degrees), it cannot be the first one. The second one is correct because of fact families. And the x+y=46 is also incorrect because x+y+46 is 180 not x+y=46.

The two seventh grade classes at VSH Middle School collected the most box tops for a school

rd period class collected
3,760 box tops and Mr. Thie’s 4th period class collected 2,301. How should they divide the money so
that each class gets the same fraction of the prize money as the fraction of the box tops that they
collected
I'll marry whoever get the best answer ;) (❤´艸｀❤)

Answers

All together, the students collected 3,760+2,301+1,855=7,916 box tops.

Mr. Aceves’ class collected 3760/7916 of the box tops.

Mrs. Baca’s class collected 2301/7916 of the box tops.

Mr. Canyon’s class collected 1855/7916 of the box tops.

The amount for Mr. Aceves’ class is 3760/7916×600≈284.99

The amount for Mrs. Baca’s class is 2301/7916×600≈174.41

The amount for Mr. Canyon’s class is 1855/7916×600≈140.60

So $284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

They didn’t say anything about diving the box tops, it’s a trick question you want to divide the money between the 2 classes so you would do 600/2 and you get 300

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

The collapse of the New York Stock Exchange triggered the Great Depression. Four-million Americans were put out of work and the economy went down the drain. European countries felt the affects of the Great Depression as well. Since the start of the Treaty of Versailles, Germany was stuck taking loans from the U.S. so that they could pay reparations to the French and British. The reparations were then used by France and Great Britain to payback the U.S. for war debts. The Germans were already struggling and the withdraw of American investments in German industries made it worse, "American investors withdrew their money from German industries, which unavoidably led to bankruptcy. At the same time, German and other European exports to the U.S. dropped to almost zero." (Klapsis 190). Germany tanked and citizens began to look for a way out. Desperation allowed for fascist leaders, like Hitler to slowly come to power. Fascism comes in stages. The first stage is the idea that the current system is not working as it should. These ideas were already floating around at the time, "In the late 19th and early 20th centuries, thinkers and publicists discredited reigning liberal and democratic values in the name of something new that promised to transcend and join them" (Paxton 11). The promise of a better future was very appealing to people who were struggling at the time. When Hitler first gained power, he significantly reduced the unemployment rate in Germany and boosted their economy. The desperation of the people disappeared, and the Nazi party gained support from the citizens. Had it not been for the Great Depression, fascist groups would never have had the chance to gain support from people and take power.
