Answer:
This year the parking lot should have 16 spaces for RVs
Step-by-step explanation:
we know that
using proportion
solve for r
Multiply in cross
therefore
This year the parking lot should have 16 spaces for RVs
x ----> the number of car spaces
r ----> the number of RV spaces
we know that
----> equation A
----> equation B
substitute equation A in equation B
solve for r

Answer:
C. 10
Step-by-step explanation:
You can take the blank as x
so 361.2 / x = 36.12
multiply by x
361.2 = 36.12x
divide
x = 10
Answer:
Step-by-step explanation:
Given: ΔDFE is isosceles with base FE; FB ≅ EC.
To prove: ΔDFB ≅ ΔDEC
Proof: It is given that ΔDFE is isosceles with base FE; FB ≅ EC, thus
From ΔDFB and ΔDEC, we have
FB≅EC (Given)
DF≅DE (Definition of isosceles triangle)
∠DFE≅∠DEF⇒∠DFB≅DEC (because DF≅DE, therefore base angles are equal)
Thus, by SAS rule,
ΔDFB ≅ ΔDEC
Statements Reasons
1. FB≅EC (Given)
2. DF≅DE (Definition of isosceles triangle)
3.∠DFE≅∠DEF
⇒∠DFB≅DEC (because DF≅DE, therefore base angles are equal)
4. ΔDFB ≅ ΔDEC SAS rule
To add complex numbers, it is necessary to group the similar terms (real and real, then imaginary and imaginary) before simplifying. This will be done as follows:
(-4 + i) + (10 - 5i)
Grouping similar terms:
(-4 + 10) + (i - 5i)
6 - 4i
From the choices, the correct answer is C.
Answer:
<u>Step-by-step explanation:</u>
Insert x = 13 and y = 1:
x² + 2hxy + 12y² = 0
(13)² + 2(13)(1) + 12(1)² = 0
169 + 26h + 12 = 0
26h + 181 = 0
26h = -181
