Answer:
Janice needs 1$ more.
Step-by-step explanation:
Multiply both price rates by 5.
(.80x5)+(1.40x5)
(4)+(7)
Add to find the total cost.
11$
Subtract the cost from the budget.
11-10=-1$
Janice needs 1$ more.
Applying the Pythagorean theorem, the length of b, to the nearest tenth, is: 11.2.
<h3>What is the Pythagorean Theorem?</h3>
The Pythagorean theorem is the theorem that is applied when finding any length of a right triangle. Where a and b are the smaller sides of the right triangle, and c is the longest side (hypotenuse) of the right triangle, the Pythagorean theorem states that: a² + b² = c².
We are given the following regarding a right triangle:
a = 10 (one of the smallest side)
c = 15 (the longest side/hypotenuse)
Plug in the values into a² + b² = c²:
10² + b² = 15²
100 + b² = 225
Subtract 100 from both sides
100 + b² - 100 = 225 - 100
b² = 125
Square both sides
√b² = √125
b ≈ 11.2
The length of b, to the nearest tenth, is: 11.2.

Step-by-step explanation:
Correct answer: "Diagonal AC is congruent to itself by the Reflexive Property of Equality."
Insert the sentence above before the sentence "Triangles BCA and DAC are congruent according to the Angle-Side-Angle (ASA)".
The congruence of two angles is already proved, so you need to prove that the corresponding pair of sides is congruent. Then you have 3 pairs of congruent elements for the Angle-Side-Angle (ASA) Theorem.
