<h3>what is unitary method?</h3>

It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

There are two situation in Unitary method:

There are 5 ice-creams. 5 ice-creams cost $125.

Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.

Step 2: To find the cost of 3 ice-creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.

Given:

If she had 12 quarters, then

12 * .25 = $3 ( quarters)

4 * .05 = $.2 ( in nickels)

Hence, she have 12 quarters.

the triangles below are congruent and their corresponding parts are marked. name all the corresponding congruent angles and side

GuDViN [60]

Answer:

See explanation

Step-by-step explanation:

The triangles below are congruent and their corresponding parts are marked.

a) Angles marked with one arc are congruent, so $\angle B\cong \angle Z.$

Angles marked with two arcs are congruent, so $\angle A\cong \angle Y.$

Angles marked with three arcs are congruent, so $\angle C\cong \angle X.$

b) Sides marked with one segment are congruent, so $\overline {AC}\cong \overline {YX}.$

Sides marked with two segments are congruent, so $\overline {BC}\cong \overline {ZX}.$

Sides marked with three segments are congruent, so $\overline {AB}\cong \overline {YZ}.$

c) Name teo congruent triangle following the congruence of angles:

$\triangle BCA\cong \triangle ZXY$

HELP ME THIS IS SO CONFUSING

Harrizon [31]

Answer:

365 degrees :)

Step-by-step explanation:

It's a multiple of 5, but with no zeros, so that means the ones place is 5. The hundreds place is two less than 5, so that's 3. And the tens place is two times the 3, so that gives you 365!

Mice21 [21]

Answer:

Let the truck is driven X miles per day

Charges of company A will be = 90+0.4X

Charges of company B will be =30+0.7X

Let us find out value of X when charges of both companies are same

which means that 90+0.4 X= 30+0.7X

90-30 = 0.7X-0.4X

60 = 0.3X

60/0.3 = X

X= 200

The charges of both companies will be same if truck is driven 200 miles per day

Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B)
