Trina uses 1/2 of sugar and 3/4 cup of flour in a recipe. How many cups of sugar would she need if she uses 3 cups of flour?

Good Morning

4hours .........1136 miles

1 hour ...........x

Cross-Multiply

4x= 1136*1

4x= 1136

x= 1136/4

x= 284

The train is traveling 284 miles per hour

I hope that's help !

Happy Sunday :)

Final answer:

To find the unit rate of the train's speed, divide the total distance traveled by the total time taken.

Explanation:

To calculate the unit rate at which the train is traveling per hour, you can apply a straightforward formula: divide the total distance covered by the total time taken. In this specific instance, the train covered a distance of 1136 miles within a time frame of 4 hours.

So, the unit rate for the train's speed is determined as follows:

Total distance traveled (1136 miles) divided by the total time taken (4 hours) equals 284 miles per hour.

This unit rate, expressed as 284 miles per hour, is a crucial metric for assessing the speed at which the train is moving. Understanding unit rates is valuable not only in transportation but also in various fields like economics, physics, and everyday calculations where quantities are compared with respect to time.

Answer:

25%

Step-by-step explanation:

To find the percent of large buttons, divide the number of large buttons by the total, and divide that by 100:

(20/80) x 100

0.25 x 100

= 25

So, 25% of the buttons were large.

Answer:

25 percent of the buttons were large

The given statement:

Only regular polygons with an even number of sides are symmetrical is a FALSE STATEMENT.

Step-by-step explanation:

A symmetrical figure or a polygon means that if it is into halves such that the halves looks similar or match exactly then the figure is said to be symmetrical.

We know that a regular polygon with 'n' number of sides has exactly n number of axis of symmetry.

Hence, no matter whether the regular polygon has even number of sides or odd number of sides it will be symmetrical.

Answer: false

Final answer:

Mac was somewhat correct in utilizing a protractor to duplicate angle TAR. However, in geometric construction, angles are usually duplicated using a compass and straight edge.

Explanation:

In terms of duplicating angle TAR to create angle MAC, Mac was somewhat correct in his use of a protractor to measure and recreate the angle. However, the exact correctness of his construction could be contingent upon additional elements. In simple terms, yes, you can duplicate an angle by using a protractor. You would simply need to measure the degree of the original angle and then replicate this on a separate point using the same degree measurement. Nonetheless, in proper geometric construction, an angle is duplicated using a compass and a straight edge rather than a protractor.

For instance, if Angle TAR measures 30 degrees, Mac will set his protractor at an intersect point M to measure and create angle MAC, that also measures 30 degrees. It's essential to note that while the measure of the angles are identical, the lengths of the sides of the angles will not necessarily be identical unless defined to be so.

Yet, using a protractor is not necessarily the exact method of angle duplication as described in classic geometric construction. There, one uses a compass and straightedge to duplicate an angle. This process generally involves drawing an initial line, creating an arc crossing the angle's sides with a compass, and then duplicating this arc on the other line to assure both angles are comparable.
